Authors: McCaffrey J A , Mazumdar M , Bajorin D F , Bosl G J , Vlamis V , Motzer R J
Published: February 2017

PURPOSE

To evaluate the efficacy and toxicity of ifosfamide- and cisplatin-containing chemotherapy as first-line salvage treatment for patients with germ cell tumors (GCT).

PATIENTS AND METHODS

Fifty-six patients with advanced GCT resistant to one prior cisplatin-containing regimen were treated with a salvage chemotherapy regimen of ifosfamide, cisplatin, and either vinblastine or etoposide (VeIP/VIP).

RESULTS

Twenty of 56 (36%) assessable patients achieved a complete response (CR). Thirteen (23%) are alive and continuously free of disease at a median follow-up time of 52 months; the median survival duration was 18 months. Among patients with a testis primary tumor site and a prior CR to first-line therapy, 65% are alive and 41% continuously disease-free, and the median survival time has not been reached. In contrast, for patients with an extragonadal primary tumor or with a testis primary tumor site and an incomplete response (IR) to first-line therapy, 31% are alive and 15% continuously free of disease, with a median survival time of 12 months (P < .03).

CONCLUSION

Ifosfamide- and cisplatin-containing therapy achieves a durable CR in a minority of patients with resistant GCT as first-line therapy. Patients with a primary testis site who relapsed from a CR to first-line cisplatin therapy have a better prognosis than patients with an extragonadal primary tumor site or an IR to first-line therapy. Risk-directed clinical trials to improve response and survival in both subsets are warranted.

PURPOSE

Although important predictors of survival in myeloma patients have been identified, it is well recognized that better prognostic factors for this disease are needed. Because cytogenetics play a dominant role in the outcome of patients with acute leukemia, their prognostic value was evaluated in a large group of newly diagnosed and previously treated myeloma patients receiving autotransplants.

METHODS

A total of 427 either newly diagnosed (26%) or previously treated patients (74%) received tandem transplants, supported by mobilized peripheral-blood stem cells. Numerous variables, including cytogenetics, were analyzed for their impact on complete remission, event-free survival (EFS), and overall survival (OS).

RESULTS

Abnormal karyotypes were detected in 37% of our patients and were very complex, irrespective of the duration of standard therapy before the first autotransplant. In addition to previously recognized unfavorable implications of partial or complete deletion of chromosome 13 and 11q abnormalities, we now observed that the presence of any translocation likewise portended poor outcome (unfavorable karyotypes). On multivariate analysis, the absence of an unfavorable karyotype was the most favorable variable for both EFS (P = .0001) and OS (P = .0001). Other favorable factors were duration of standard therapy and a low beta-2 microglobulin (B2M) level before the first autotransplant. A risk-based classification system was developed according to the number of these favorable variables present, showing highly significant differences in event-free and overall survival.

CONCLUSION

Cytogenetics play a dominant role in myeloma and were independent of previously recognized important prognostic factors, such as B2M and duration of prior standard therapy.
Irradiation in the setting of collagen vascular disease: acute and late complications.
Authors: Morris M M , Powell S N
Published: February 2017

PURPOSE

Based on reports of greater toxicity from radiation therapy, collagen vascular diseases (CVDs) have been considered a contraindication to irradiation. We assessed the complications of radiation therapy in patients with CVD.

PATIENTS AND METHODS

A total of 209 patients with documented CVD were irradiated between 1960 and 1995. One hundred thirty-one had rheumatoid arthritis (RA), 25 had systemic lupus erythematosus (SLE); 17 had polymyositis or dermatomyositis; 16 had scleroderma; eight had ankylosing spondylitis; five had juvenile RA; three had discoid lupus erythematosus; and four had 4 mixed connective tissue disorders (MCTD). The mean follow-up duration of curative cases was more than 6 years. Doses ranged from 10 to 87.6 Gy, with a median of 45 Gy.

RESULTS

Overall, 263 sites were assessable in 209 patients. Significant (> or = grade 3) acute toxicity was seen in 10% of irradiated sites. Severe late effects were associated with significant acute reactions and with non-RA CVDs (6% v 21% at 5 years). No difference was seen in late effects according to timing of CVD onset, presence of concurrent vascular insults, radiation dose, or other technical factors, or by measures of disease activity.

CONCLUSION

RA does not appear to have an elevated rate of late toxicity. While non-RA CVD is significantly associated with increased radiation late effects at standard doses, radiation-related mortality remains exceedingly rare. The choice of therapeutic modality in this radiosensitive group of patients should be made on a case-by-case basis.
Detection of metastatic neuroblastoma in bone marrow: when is routine marrow histology insensitive?
Authors: Cheung N K , Heller G , Kushner B H , Liu C , Cheung I Y
Published: February 2017

PURPOSE

To measure the sensitivity of histologic examination in detecting metastatic solid tumor in bone marrow.

PATIENTS AND METHODS

A total of 145 patients with stage 4 neuroblastoma underwent 840 marrow examinations, each consisting of six sites (four aspirates and two biopsies), from October 1990 to June 1996 at Memorial Sloan-Kettering Cancer Center. Metastasis was detected by either histology (aspirate by Wright-Giemse and biopsy by Hematoxylin-Eosin stains) or immunostaining of aspirates using anti-G(D2) monoclonal antibodies.

RESULTS

The absence of tumor by histology at a single marrow site was a poor guarantee of the absence of disease. The number of false-negative sites increased as the percent of G(D2)-positive tumor cells in the marrow decreased: zero of six if tumor cell count was > or = 1%, and approximately six of six sites if < or = 0.003%. Sensitivity was comparable between marrow aspirate and biopsy. A lower bound (LB) for the probability of false-negative histology was calculated from the (1) discordance among the six marrow samplings and (2) comparison with immunofluorescence. When disease was extensive (eg, at diagnosis), the LB was 0.13 and 0.3, respectively. After treatment, it increased to 0.37 and 0.8. Examining multiple marrow sites can decrease the LB to 0.15. However, at least three sites have to be negative at relapse, six at diagnosis, and more than 50 during treatment or off-therapy follow-up. The marginal decrease in the LB by additional samplings rapidly diminished to less than 0.05 after two sites.

CONCLUSION

Except at diagnosis and relapse when gross disease is present, marrow sampling by histology has limited sensitivity. Current practice grossly underestimates the true prevalence of marrow disease.
Detection of circulating melanoma cells by specific amplification of tyrosinase complementary DNA is not a reliable tumor marker in melanoma patients: a clinical two-center study.
Authors: Gläser R , Rass K , Seiter S , Hauschild A , Christophers E , Tilgen W
Published: February 2017

PURPOSE

Recently, the reverse-transcription polymerase chain reaction (RT-PCR) of tyrosinase messenger RNA (mRNA) was reported to be a useful tool for the detection of circulating tumor cells in the peripheral blood of melanoma patients. Our aim was to evaluate critically the diagnostic value of this marker by investigating a significant number of patients in different stages of the disease in a two-center study.

PATIENTS AND METHODS

Different techniques of blood collection, RNA isolation, and RT-PCR were compared, and the detectability of tyrosinase mRNA was tested using nine different melanoma cell lines. The sensitivity of the method was confirmed by blood spiking experiments and the specificity by restriction enzyme analysis. Subsequently, a total of 153 blood samples from 137 individuals (30 healthy subjects, five basal cell carcinoma, and 102 melanoma patients) were investigated.

RESULTS

The detection level of melanoma cells differed between the cell lines tested. However, we could reproducibly detect single melanoma cells by spiking whole blood samples from healthy volunteers. One of 43 patients with primary melanoma (2.3%), zero of 15 patients with regional metastasis (0%), and 12 of 44 patients with advanced disease (27.3%) were found to be RT-PCR positive. All blood samples obtained from controls and patients with basal cell carcinoma were tyrosinose mRNA negative.

CONCLUSION

Our data support the recent doubts that the detection of circulating tumor cells in melanoma patients using the tyrosinase mRNA RT-PCR is not sensitive enough to be used either as a melanoma progression marker in early stages of the disease or to monitor therapy in advanced stages of the disease.
Preirradiation paclitaxel in glioblastoma multiforme: efficacy, pharmacology, and drug interactions. New Approaches to Brain Tumor Therapy Central Nervous System Consortium.
Authors: Fetell M R , Grossman S A , Fisher J D , Erlanger B , Rowinsky E , Stockel J , Piantadosi S
Published: February 2017

PURPOSE

The purpose of this study was to determine the response rate of paclitaxel administered at maximal tolerated doses (MTD) in patients with newly diagnosed glioblastoma multiform.

PATIENTS AND METHODS

All patients in this multicenter study were 45 years or older and had measurable residual tumor on postoperative MRI scans. Up to 3 cycles of paclitaxel were administered as a continuous 96-hour intravenous infusion prior to radiation, provided that the tumor did not enlarge on serial MRIs. The initial 10 patients were treated with the previously recommended phase II dose of 140 mg/m2. Less than anticipated toxicity led to the development of a phase I/II study in 24 patients in which paclitaxel doses were escalated separately in patients receiving (+EIAED) or not receiving (-EIAED), concomitant enzyme-inducing antiepileptic drugs. Paclitaxel plasma steady-state concentrations (Css) were measured during the first cycle of chemotherapy. Response was the primary efficacy endpoint for this study, although survival was also assessed.

RESULTS

The MTD was 140 mg/m2 in the -EIAED, and 200 mg/m2 in the +EIAED patient groups. The mean Css for the -EIAED patients treated at 140 mg/m2 was 38 nM, whereas the mean Css for +EIAED patients were 17 nm at 140 mg/m2, 27 nM at 175 mg/m2, 46 nM at 200 mg/m2, and 51 nM at 230 mg/m2. One patient, who had a verified partial response, had his diagnosis changed to an anaplastic oligodendroglioma on subsequent central neuropathologic review. None of the 15 assessable glioblastoma patients treated at or above the MTD doses showed a radiographic response to paclitaxel. The median survival of eligible patients on this protocol was 355 days (95% CI, 255 to 485 days), which is similar to the survival of comparable patients treated with conventional therapy.

CONCLUSIONS

These results suggest that (1) paclitaxel given as a 96-hour infusion at the MTD has minimal activity in patients with untreated glioblastoma, (2) the concomitant administration of EIAEDs alters the pharmacology of paclitaxel, resulting in a lower Css, reduced systemic toxicity, and higher dose requirements, (3) this study design, in which a new agent is given prior to radiation therapy (with serial monitoring of MRI), did not adversely affect survival in this patient population.
Germ-line BRCA1 mutations in women with sporadic breast cancer: clinical correlations.
Authors: Garcia-Patiño E , Gomendio B , Provencio M , Silva J M , Garcia J M , España P , Bonilla F
Published: February 2017

PURPOSE

Sporadic nonhereditary breast cancer is recognized as the most common form of this malignancy. Presence of germ-line mutations in the BRCA1 gene of these tumors is an infrequent event. We undertook the present study to evaluate the prevalence of germ-line mutations in patients diagnosed with sporadic breast cancer, and to delimit the clinical spectrum of this subgroup of patients with germ-line mutations and their differences with respect to patients with no evidence of BRCA1 gene mutations.

METHODS

We studied 105 patients diagnosed with breast cancer, selected from among our living patients; those with carcinoma-in-situ and those with a definite family history of breast or ovarian cancer were excluded. Genomic DNA, obtained from peripheral-blood lymphocytes, was studied for BRCA1 mutations by polymerase chain reaction/single-strand conformation polymorphism (PCR-SSCP) and direct DNA sequencing. Fourteen clinicopathologic parameters were analyzed in each patient.

RESULTS

Six (5.7%) frameshift mutations that corresponded to truncating proteins and three missense mutations, the functional meaning of which remains speculative, were identified. The patients with germ-line mutations were found to have a more advanced age at diagnosis, as well as a longer median survival (51 months).

CONCLUSION

Women with sporadic breast cancer of late onset may display a significant incidence of germline BRCA1 mutations, which occur at a rate not previously determined in this group of patients. The presence of variations in the sequence of the BRCA1 gene could influence the longer survival observed in these patients.
High-dose chemoradiotherapy and anti-B-cell monoclonal antibody-purged autologous bone marrow transplantation in mantle-cell lymphoma: no evidence for long-term remission.
Authors: Freedman A S , Neuberg D , Gribben J G , Mauch P , Soiffer R J , Fisher D C , Anderson K C , Andersen N , Schlossman R , Kroon M , Ritz J , Aster J , Nadler L M
Published: February 2017

PURPOSE

The role for high-dose therapy and autologous stem-cell transplantation in mantle-cell lymphoma (MCL) is unknown. We retrospectively analyzed patients with chemosensitive disease who underwent high-dose chemoradiotherapy and anti-B-cell monoclonal antibody-purged autologous bone marrow transplantation (ABMT) for MCL in first remission, as well as following relapse from conventional therapy.

PATIENTS AND METHODS

Between August 1985 and April 1996, 28 patients underwent ABMT using a uniform ablative regimen with cyclophosphamide and total-body irradiation (TBI) and a bone marrow-purging regimen. Re-review of original tissue demonstrated that all patients had morphologic, phenotypic, and genotypic characteristics of MCL. MCL was the original diagnosis in 21 patients, whereas seven patients had a prior diagnosis of diffuse small cleaved-cell lymphoma.

RESULTS

Twenty patients received multiple regimens before ABMT, while eight underwent ABMT in first complete remission (CR)/partial remission (PR) following CHOP induction. At bone marrow harvest, only 18% of patients were in CR and overt BM infiltration was present in 57%. Following cyclophosphamide/TBI, no treatment-related deaths were seen. Nineteen of 28 patients have relapsed at a median time of 21 months (range, 3 to 70). Of eight patients transplanted in first CR/PR, five have relapsed. Nine patients are in continuous CR with a median follow-up time of 24 months (range, 10 to 135). Disease-free survival (DFS) and overall survival (OS) are estimated to be 31% and 62% at 4 years, respectively.

CONCLUSION

ABMT using cyclophosphamide/TBI conditioning may at best be effective in only a small fraction of patients with relapsed MCL. The lack of plateau with a median follow-up time of 24 months suggests cure may not be achievable. The role of this therapy in patients in first remission requires more study using better induction therapy to enhance the CR rate before ABMT.
Intermediate-dose intravenous methotrexate with intravenous mercaptopurine is superior to repetitive low-dose oral methotrexate with intravenous mercaptopurine for children with lower-risk B-lineage acute lymphoblastic leukemia: a Pediatric Oncology Group phase III trial.
Authors: Mahoney D H , Shuster J , Nitschke R , Lauer S J , Winick N , Steuber C P , Camitta B
Published: February 2017

PURPOSE

To determine whether early intensification with 12 courses of intravenous methotrexate and intravenous mercaptopurine (IVMTX/IVMP) is superior to 12 courses of repetitive, low-dose oral MTX with I.V. MP (LDMTX/IVMP) for prevention of relapse in children with lower-risk B-lineage acute lymphoblastic leukemia (ALL).

PATIENTS AND METHODS

Seven hundred nine patients were entered onto the study. Vincristine, prednisone, and asparaginase were used for remission induction. Patients were randomized to receive intensification with either IVMTX 1,000 mg/m2 plus IVMP 1,000 mg/m2 (regimen A) or LDMTX 30 mg/m2 every 6 hours for six doses with IVMP 1,000 mg/m2 (regimen B). Twelve courses were administered at 2-week intervals. Triple intrathecal therapy (TIT) was used for CNS prophylaxis. Continuation therapy included standard oral MP, weekly MTX, and TIT every 12 weeks for 2 years.

RESULTS

Six hundred ninety-nine (99%) patients achieved remission. Three hundred forty-nine were assigned to regimen A and 350 to regimen B. The estimated 4-year continuous complete remission (CCR) rate for patients treated with regimen A is 80.3% (SE = 2.9%) and with regimen B is 75.9% (SE = 3.1%). By log-rank analysis, regimen A demonstrated superior CCR (P = .013). Transient neutropenia/thrombocytopenia, bacterial sepsis, neurotoxicity, stomatitis, and hospitalizations were more frequent among patients treated on regimen A.

CONCLUSION

Intensification with IVMTX/IVMP is more effective than LDMTX/IVMP for prevention of relapse in children with B-precursor ALL at lower risk for relapse.
Phase II trial of preoperative radiation therapy and chemotherapy for patients with localized, resectable adenocarcinoma of the pancreas: an Eastern Cooperative Oncology Group Study.
Authors: Hoffman J P , Lipsitz S , Pisansky T , Weese J L , Solin L , Benson A B
Published: February 2017

PURPOSE

A prospective, multiinstitutional trial was initiated in 1991 to examine the tolerance to and efficacy of a program of preoperative chemoradiotherapy (CTRT) and surgical resection for patients with localized adenocarcinoma of the pancreas.

PATIENTS AND METHODS

Fifty-three patients were assessable for analysis, with a median follow-up of 52 months for survivors. Radiation therapy (RT) totaling 5,040 cGy in 180 cGy fractions with mitomycin 10 mg/m2 day 2 and fluorouracil (5-FU) 1,000 mg/m2/d continuous infusion days 2 through 5 and 29 through 32 were given as preoperative adjuvant therapy. Twelve patients did not proceed to surgery (one death, one toxicity, three local progression, six distant metastases, one intercurrent illness), whereas 41 patients underwent surgery. Of these, 17 patients did not have resection (11, hepatic and/or peritoneal metastases and six local extension that precluded resection). Twenty-four patients had tumor resection (19 Whipple, four total pancreatectomy, one distal pancreatectomy).

RESULTS

Treatment toxicity was primarily hematologic, although a comparable number suffered biliary tract complications, either from obstruction or cholangitis as a result of an occluded stent or the primary tumor. There was one postoperative death. Median survival for the entire group and for the 24 patients with resection was 9.7 and 15.7 months. This survival rate reflected the advanced state of most resected cancers (positive peritoneal cytology, three patients; margins within 2 mm, 13 patients; involved lymph nodes, four patients; and need for superior mesenteric vein (SMV) resection, four patients). Tumor progression was most frequent at metastatic sites.

CONCLUSION

This preoperative CTRT protocol was feasible and safe in a cooperative group setting. Entry of patients with advanced tumors probably accounted for the suboptimal resectability and survival results.
Phase I study of bryostatin 1 in patients with relapsed non-Hodgkin's lymphoma and chronic lymphocytic leukemia.
Authors: Varterasian M L , Mohammad R M , Eilender D S , Hulburd K , Rodriguez D H , Pemberton P A , Pluda J M , Dan M D , Pettit G R , Chen B D , Al-Katib A M
Published: February 2017

PURPOSE

To define, in a phase I study in relapsed non-Hodgkin's lymphoma (NHL) and chronic lymphocytic leukemia (CLL), the maximum-tolerated dose (MTD), major toxicities, and possible antitumor activity of bryostatin 1, a macrocyclic lactone.

PATIENTS AND METHODS

Bryostatin 1 was delivered by 72-hour continuous infusion every 2 weeks to patients with relapsed NHL or CLL, at doses that ranged from 12 microg/m2 to 180 microg/m2 per course. Correlative investigations included evaluations of total protein kinase C (PKC) in peripheral blood and lymphoid differentiation in patient tumor tissue.

RESULTS

Twenty-nine patients were treated, including three patients with CLL and 26 with NHL. Generalized myalgia was the dose-limiting toxicity (DLT) and occurred in two of three patients treated with bryostatin 1 at 180 microg/m2 per course. Myalgias were dose-related and cumulative, and often started in the thighs and calves, improved with activity, were somewhat responsive to analgesics, and often took weeks to resolve once taken off study. Six patients were treated at the MTD of 120 microg/m2 per course. Myalgia, headache, and fatigue were common. Hematologic toxicity was uncommon. Total cumulative doses of bryostatin 1 up to 1,134 microg/m2 have been administered without untoward toxicity. Eleven patients achieved stable disease for 2 to 19 months. An in vitro assay for total PKC evaluation in patient peripheral-blood samples demonstrated activation within the first 2 hours with subsequent downregulation by 24 hours, which was maintained throughout the duration of the 72-hour infusion.

CONCLUSION

This phase I study defined the MTD and recommended phase II dose of bryostatin 1, when administered over 72 hours every 2 weeks, to be 120 microg/m2 (40 microg/m2/d for 3 days). Generalized myalgia was the DLT. Future studies will define the precise activity of bryostatin 1 in subsets of patients with lymphoproliferative malignancies and its efficacy in combination with other agents.
Dose-titration, multicenter study of oral transmucosal fentanyl citrate for the treatment of breakthrough pain in cancer patients using transdermal fentanyl for persistent pain.
Authors: Christie J M , Simmonds M , Patt R , Coluzzi P , Busch M A , Nordbrock E , Portenoy R K
Published: February 2017

PURPOSE

Supplemental, "as-needed," administration of an opioid is a common approach to the problem of breakthrough pain in cancer patients. Oral transmucosal fentanyl citrate (OTFC) is undergoing investigation as a new treatment for breakthrough pain. The primary purpose of the study was to demonstrate that a single-unit dose of OTFC can safely and effectively treat breakthrough pain. A secondary goal was to determine appropriate dosing guidelines.

PATIENTS AND METHODS

This was a multicenter, randomized, double-blind, dose-titration study in 62 adult cancer patients using transdermal fentanyl for persistent pain. Consenting patients provided 2 days of baseline data to evaluate the performance of their usual breakthrough pain medication. Patients then randomly received 200 microg or 400 microg OTFC in double-blind fashion. (Patients were always assigned, rather than randomized, to 200 microg if 400 microg represented > 20% of around-the-clock medication.) Pain intensity (PI), pain relief (PR), and global satisfaction scores were recorded. OTFC was then titrated until the patient received adequate PR for each episode using one OTFC unit. Orders to titrate up were ignored one third of the time to improve the blind. Two days of baseline data were compared with 2 days of OTFC data after titration identified an effective dose of OTFC.

RESULTS

Most patients (76%) found a safe and effective dose of OTFC. There was no meaningful relationship between the around-the-clock opioid regimen and the effective dose of OTFC. In open-label comparisons, OTFC produced a faster onset of relief and a greater degree of PR than patients' usual breakthrough medication. Somnolence, nausea, and dizziness were the most common side effects associated with OTFC.

CONCLUSION

Most patients find a single OTFC dosage that adequately treats breakthrough pain. The optimal dose is found by titration and is not predicted by around-the-clock dose of opioids.
Maximum-tolerated dose, toxicity, and efficacy of (131)I-Lym-1 antibody for fractionated radioimmunotherapy of non-Hodgkin's lymphoma.
Authors: DeNardo G L , DeNardo S J , Goldstein D S , Kroger L A , Lamborn K R , Levy N B , McGahan J P , Salako Q , Shen S , Lewis J P
Published: February 2017

PURPOSE

Lym-1, a monoclonal antibody that preferentially targets malignant lymphocytes, has induced remissions in patients with non-Hodgkin's lymphoma (NHL) when labeled with iodine 131 ((131)I). Based on the strategy of fractionating the total dose, this study was designed to define the maximum-tolerated dose (MTD) and efficacy of the first two, of a maximum of four, doses of (131)I-Lym-1 given 4 weeks apart. Additionally, toxicity and radiation dosimetry were assessed.

MATERIALS AND METHODS

Twenty patients with advanced NHL entered the study a total of 21 times. Thirteen (62%) of the 21 entries had diffuse large-cell histologies. All patients had disease resistant to standard therapy and had received a mean of four chemotherapy regimens. (131)I-Lym-1 was given after Lym-1 and (131)I was escalated in cohorts of patients from 40 to 100 mCi (1.5 to 3.7 GBq)/m2 body surface area.

RESULTS

Mean radiation dose to the bone marrow from body and blood (131)I was 0.34 (range, 0. 1 6 to 0.63) rad/mCi (0.09 mGy/MBq; range, 0.04 to 0.17 mGy/ MBq). Dose-limiting toxicity was grade 3 to 4 thrombocytopenia with an MTD of 100 mCi/m2 (3.7 GBq/m2) for each of the first two doses of (131)I-Lym-1 given 4 weeks apart. Nonhematologic toxicities did not exceed grade 2 except for one instance of grade 3 hypotension. Ten (71 %) of 14 entries who received at least two doses of (131)I-Lym-1 therapy and 11 (52%) of 21 total entries responded. Seven of the responses were complete, with a mean duration of 14 months. All three entries in the 100 mCi/m2 (3.7 MBq/m2) cohort had complete remissions (CRs). All responders had at least a partial remission (PR) after the first therapy dose of (131)I-Lym-1.

CONCLUSION

(131)I-Lym-1 induced durable remissions in patients with NHL resistant to chemotherapy and was associated with acceptable toxicity. The nonmyeloablative MTD for each of the first two doses of (131)I-Lym-1 was 100 mCi/m2 (total, 200 mCi/m2) (3.7 GBq/m2; total, 7.4 GBq/m2).
Topotecan for the treatment of advanced epithelial ovarian cancer: an open-label phase II study in patients treated after prior chemotherapy that contained cisplatin or carboplatin and paclitaxel.
Authors: Bookman M A , Malmström H , Bolis G , Gordon A , Lissoni A , Krebs J B , Fields S Z
Published: February 2017

PURPOSE

Topotecan, a topoisomerase I inhibitor, was evaluated in a multicenter, phase II study of women with epithelial ovarian carcinoma who relapsed after one or two prior regimens that included platinum and paclitaxel.

PATIENTS AND METHODS

Topotecan 1.5 mg/m2 daily was administered as a 30-minute infusion for 5 consecutive days on a 21-day cycle. Eligibility criteria included bidimensionally measurable disease, Eastern Cooperative Oncology Group performance status of 2 or less, and adequate bone marrow, liver, and renal function. Efficacy was assessed by independent radiologic review.

RESULTS

One hundred thirty-nine patients were treated; 81% were platinum resistant. Sixty-two patients had received one prior regimen and 77 patients had received two prior regimens. Nine patients were not assessable for response; however, all patients were included in the response analysis. The overall response rate was 13.7%; 12.4% in platinum-resistant and 19.2% in platinum-sensitive patients. Stable disease lasted at least 8 weeks in 27.3% of the patients. The median duration of response and time to progression were 18.1 and 12.1 weeks, respectively. The median survival was 47.0 weeks. Grade 4 neutropenia occurred in 82% of the patients (34% of the courses) and thrombocytopenia in 30% of the patients (9% of the courses). Infectious complications occurred in 6% of the courses. Nonhematologic toxicities were mild. There were no drug-related toxic deaths.

CONCLUSION

As a single agent, topotecan has modest activity in women with advanced epithelial ovarian carcinoma who have progressed or not responded after one or two prior regimens with platinum and paclitaxel. Further investigation of combination regimens is indicated in the primary therapy for ovarian cancer based on the mechanism of action and tolerability.
Docetaxel and cisplatin in metastatic urothelial cancer: a phase II study.
Authors: Sengeløv L , Kamby C , Lund B , Engelholm S A
Published: February 2017

PURPOSE

Docetaxel and cisplatin has documented single-agent activity and different toxicity profiles in patients with metastatic urothelial cancer. We performed a phase II study in which docetaxel was combined with cisplatin to evaluate response rate, toxicity, and survival.

PATIENTS AND METHODS

Eligibility criteria included performance status (World Health Organization [WHO]) less than 3; normal bone marrow, liver, and renal function; and no concurrent malignancy or symptomatic peripheral neuropathy. Docetaxel (Taxotere; Rhône-Poulenc Rorer, Paris, France) 75 mg/m2 was combined with cisplatin 75 mg/m2 every third week. Patients received premedication with prednisolone and clemastine.

RESULTS

A total of 25 patients were assessable for response and toxicity. Median age was 64 years; five patients had locoregional disease only and 20 had metastatic disease. Response was achieved in 15 patients (60%; 95% confidence interval [CI], 39% to 79%), including seven patients (26%) who achieved a complete response. Overall median survival time was 13.6 months (range, 1.5 to 26.4+). The most frequent toxicity was nausea and vomiting (80% of patients). Neutropenia grade 3 or 4 was observed in 56% of patients, but only one had febrile neutropenia. Mucositis and diarrhea were encountered in 13% of cycles, mostly grade 1 or 2. Peripheral neuropathy and skin changes grade 1 and 2 were observed in 76% and 36%, respectively. Fluid retention and hypersensitivity reactions were infrequent and mild.

CONCLUSION

The combination of docetaxel and cisplatin is effective and feasible in patients with metastatic urothelial cancer with a manageable safety profile.
Quality-of-life benefit in chemotherapy patients treated with epoetin alfa is independent of disease response or tumor type: results from a prospective community oncology study. Procrit Study Group.
Authors: Demetri G D , Kris M , Wade J , Degos L , Cella D
Published: February 2017

PURPOSE

To evaluate prospectively the effectiveness of epoetin alfa as an adjunct to chemotherapy in patients with cancer based on changes in quality-of-life parameters and hemoglobin levels, and to correlate these changes with antitumor response.

PATIENTS AND METHODS

Two thousand three hundred seventy patients with nonmyeloid malignancies who received chemotherapy were enrolled onto this study from 621 US community-based practices. Patients received epoetin alfa 10,000 U three times weekly, which could be increased to 20,000 U three times weekly depending on the hemoglobin response at 4 weeks. Treatment continued for a maximum of 16 weeks in patients who showed evidence of hematologic response.

RESULTS

Two thousand two hundred eighty-nine patients (97%) were eligible for efficacy analyses. Epoetin alfa therapy was associated with improved quality-of-life parameters; these improvements correlated significantly with hemoglobin levels and were independent of tumor response. Provider-reported Karnofsky performance scores did not correlate with the improved quality-of-life changes. Epoetin alfa therapy was also associated with a significant increase in hemoglobin levels and decrease in transfusion use. Tumor type, chemotherapy agent/regimen, prior chemotherapy, baseline hemoglobin level, and baseline erythropoietin level were not predictive of a positive response to treatment. Epoetin alfa was well tolerated.

CONCLUSION

Epoetin alfa appears to have a beneficial impact on patient-reported functional capacity and quality of life in patients with cancer who received chemotherapy independent of tumor response. Concordantly, epoetin alfa appeared to increase hemoglobin levels and decrease transfusion use. Patients responded across all tumor types. The results suggest that epoetin alfa effectively improves functional outcomes in patients with cancer who receive chemotherapy.

PURPOSE

To assess the feasibility, toxicity, and efficacy of hyperfractionated accelerated radiation therapy (HART) for non-small-cell lung cancer (NSCLC).

PATIENTS AND METHODS

Thirty patients from six institutions with stage IIIA or IIIB NSCLC were enrolled between November 1993 and August 1995. Radiation therapy (total dose, 57.6 Gy in 36 fractions) was delivered over 15 days with the use of three daily fractions with a 4-hour interval between fractions and an 8-hour interval between on-cord fields. Patients were not treated on weekends.

RESULTS

Twenty-eight patients (93%) completed radiation therapy. Treatment-related toxicities of grade 3 or greater included esophagitis in six patients and grade 3 skin reaction in three patients. The overall objective response rate was 54%, and the response rate within the radiation field was 64%. With a minimum follow-up of 19 months in surviving patients, the median survival and 1-year survival rate are 13 months and 57%, respectively. The median relapse-free survival and 1-year relapse-free survival rate are 7 months and 23%, respectively. No transverse myelitis or late toxicities of grade 4 or greater have been observed.

CONCLUSION

HART, delivered to a total dose of 57.6 Gy over 15 total days, is practical and well tolerated. Survival appears similar to that seen with modern combined modality regimens. A phase III trial is under way.

PURPOSE

To review our experience using full-dose external reirradiation given with a curative intent for patients with unresectable head and neck carcinoma (HNC).

PATIENTS AND METHODS

Between January 1980 and December 1996, 169 patients who presented with unresectable nonmetastatic HNC in a previously irradiated area were included in this series. The median time between the first and the second irradiation was 33 months. Reirradiation protocols were as follows: radiotherapy alone (65 Gy over 6.5 weeks at 2 Gy/d), 27 patients; Vokes protocol, ie, five to six cycles of radiotherapy (median total dose, 60 Gy; 2 Gy/d) with simultaneous fluorouracil (5-FU) and hydroxyurea, 106 patients; and bifractionated radiotherapy (median total dose, 60 Gy; 2 x 1.5 Gy/d) with concomitant mitomycin, 5-FU, and cisplatin, 36 patients. The median cumulative dose of the two irradiations was 120 Gy. Eighty-five percent of the tumors were squamous cell carcinoma, 14% undifferentiated carcinoma of nasopharyngeal type, and 1% adenocarcinoma. Forty-four percent were local recurrences, 23% nodal recurrences, 14% both local and nodal, and 19% second primary tumors.

RESULTS

Mucositis grade 3 (World Health Organization [WHO]) was found in 32% and grade 4 in 14% of cases. Four patients presented with neutropenia or thrombocytopenia (grade 3 or 4 WHO). Late toxicities (> 6 months) were as follows: cervical fibrosis (grade 2 to 3 Radiation Therapy Oncology Group [RTOG]), 41%; mucosal necrosis, 21%; osteoradionecrosis, 8%; and trismus, 30%. Five patients died of carotid hemorrhage, apparently in complete remission. Six months after the onset of reirradiation, 37% of patients were in complete response. Patterns of failure were local only (53%), nodal only (20%), metastatic only (7%), and multiple (20%). Median follow-up time was 70 months. Overall survival rate (Kaplan-Meier) was 21% (95% confidence interval [CI], 15% to 29%) at 2 years and 9% (95% CI, 5% to 16%) at 5 years. Median survival time was 10 months for the entire population. Thirteen patients, of whom 12 were treated with the Vokes protocol, were long-term disease-free survivors. In a multivariate analysis, the volume of the second irradiation was the only factor significantly associated with the risk of death: relative risk=1.8 (95% CI, 1.13 to 5.7) (P=.01).

CONCLUSION

Full-dose reirradiation combined with chemotherapy was feasible in patients with inoperable HNC. The incidence and severity of late toxicity was markedly increased in comparison to that observed after the first irradiation. Median survival was better than that generally obtained using palliative chemotherapy alone. A small proportion of patients were long-term disease-free survivors.

PURPOSE

To assess the efficacy of neoadjuvant methotrexate, cisplatin, and vinblastine (MCV) chemotherapy in patients with muscle-invading bladder cancer treated with selective bladder preservation.

PATIENTS AND METHODS

One hundred twenty-three eligible patients with tumor, node, metastasis system clinical stage T2 to T4aNXMO bladder cancer were randomized to receive (arm 1, n=61 ) two cycles of MCV before 39.6-Gy pelvic irradiation with concurrent cisplatin 100 mg/m2 for two courses 3 weeks apart. Patients assigned to arm 2 (n=62) did not receive MCV before concurrent cisplatin and radiation therapy. Tumor response was scored as a clinical complete response (CR) when the cystoscopic tumor-site biopsy and urine cytology results were negative. The CR patients were treated with an additional 25.2 Gy to a total of 64.8 Gy and one additional dose of cisplatin. Those with less than a CR underwent cystectomy. The median follow-up of all patients who survived is 60 months.

RESULTS

Seventy-four percent of the patients completed the protocol with, at most, minor deviations; 67% on arm 1 and 81% on arm 2. The actuarial 5-year overall survival rate was 49%; 48% in arm 1 and 49% in arm 2. Thirty-five percent of the patients had evidence of distant metastases at 5 years; 33% in arm 1 and 39% in arm 2. The 5-year survival rate with a functioning bladder was 38%, 36% in arm 1 and 40% in arm 2. None of these differences are statistically significant.

CONCLUSION

Two cycles of MCV neoadjuvant chemotherapy were not shown to increase the rate of CR over that achieved with our standard induction therapy or to increase freedom from metastatic disease. There was no impact on 5-year overall survival.
Downregulation of transcription factor AP-2 predicts poor survival in stage I cutaneous malignant melanoma.
Authors: Karjalainen J M , Kellokoski J K , Eskelinen M J , Alhava E M , Kosma V M
Published: February 2017

PURPOSE

The transcription factor, activator protein (AP)-2, a 52-kd DNA-binding protein, is suggested to inhibit tumor growth through the activation of p21. To test this hypothesis, we analyzed AP-2 and p21 protein expressions in stage I cutaneous malignant melanomas to clarify their significance with regard to tumor progression and survival.

PATIENTS AND METHODS

A consecutive series of 369 clinical stage I cutaneous malignant melanoma patients were investigated using immunohistochemistry. The detected expression levels were correlated with each other, with clinicopathologic data, and with melanoma survival.

RESULTS

The loss of AP-2 expression was significantly associated with low p21 expression (P=.007), high tumor thickness (P=.001), high Clark's level (P=.046), high tumor-node-metastasis (TNM) category (P=.006), recurrent disease (P=.001), and male sex (P=.03). Tumor thickness, Clark's level, TNM category, bleeding, AP-2 index, and sex were all important predictors of both recurrence-free survival (RFS) and overall survival (OS) of melanoma in this order. In Cox's multivariate analysis, high tumor thickness (P=.0001), low AP-2 index (P=.0153), and bleeding (P=.0143) predicted poor RFS. Poor OS was predicted by high tumor thickness (P=.0008) and bleeding (P=.0092).

CONCLUSION

The loss of AP-2 expression seems to be associated with malignant transformation and tumor progression in cutaneous malignant melanoma. This tumor-suppressive action of AP-2 may be mediated through p21 regulation. Furthermore, decreased AP-2 expression is independently associated with elevated risk of subsequent metastatic behavior of stage I cutaneous malignant melanoma.
Prognostic factors in the treatment of human immunodeficiency virus-associated non-Hodgkin's lymphoma: analysis of AIDS Clinical Trials Group protocol 142--low-dose versus standard-dose m-BACOD plus granulocyte-macrophage colony-stimulating factor.

Published: February 2017

PURPOSE

The overall results of chemotherapy in human immunodeficiency virus (HIV)-associated non-Hodgkin's lymphoma (NHL) have been poor. To define a subgroup of patients who may have a better outcome, an analysis of prognostic factors was performed of patients treated in AIDS Clinical Trials Group (ACTG) protocol 142, a phase III randomized trial of low-dose versus standard-dose methotrexate, bleomycin, doxorubicin, cyclophosphamide, vincristine, and dexamethasone (m-BACOD) plus granulocyte-macrophage colony-stimulating factor (GM-CSF) for the treatment of patients with newly diagnosed HIV-associated NHL.

MATERIALS AND METHODS

The following baseline variables were included as potential predictors of survival among 192 patients who received treatment: age; intravenous drug use (IVDU); specific type of sexual contact as risk factors (homosexual, bisexual, or heterosexual contact); prior AIDS diagnosis; CD4 cell count; serum lactic acid dehydrogenase (LDH); histology; Karnofsky performance status (KPS); stage; B symptoms; race (white/nonwhite); nodal involvement; extranodal involvement; number of extranodal sites; specific sites: bone marrow, liver, kidney, lung, or gastrointestinal tract; and treatment arm (standard-dose m-BACOD/low-dose m-BACOD).

RESULTS

Age greater than 35 years, IVDU, stages III/IV, and CD4 cell counts less than 100/microL were adverse prognostic factors in multivariate analyses using the Cox proportional hazards model. The median overall survival for patients with none or one of the adverse factors was 46 weeks, with two was 44 weeks, and with three or four was 18 weeks. At 144 weeks, 29.5% of patients with none or one, 16.9% with two, and 0% with three or four factors were alive (P < .001).

CONCLUSION

Long-term survival can be achieved in approximately one third of patients with HIV-associated NHL with favorable characteristics.
Residual disease detection using fluorescent polymerase chain reaction at 20 weeks of therapy predicts clinical outcome in childhood acute lymphoblastic leukemia.

Published: February 2017

PURPOSE

Ninety-five percent of children with acute lymphoblastic leukemia (ALL) will achieve a remission, but approximately 25% will relapse. Identifying these patients is difficult, as patients with adverse prognostic features at presentation are rare and the majority are standard risk. Analysis of minimal residual disease (MRD) may be able to determine those at risk of relapse, but the best method by which this can be accomplished has yet to be defined. The object of this study was to determine the predictive value of residual disease detection in a group of standard-risk patients with precursor-B ALL at a fixed point in therapy (week 20) using a simple fluorescent consensus immunoglobulin H (IgH) heavy chain polymerase chain reaction (PCR).

PATIENTS AND METHODS

Forty-two patients who presented with precursor-B ALL with standard-risk clinical features and treated according to either the Medical Research Council (MRC) UKALL X or XI protocols were assessed using a combination of both fluorescent consensus framework I and framework III Ig heavy-chain PCR. The results of the PCR were analyzed on an ABI 373 gene sequencer with genescan software (Applied Biosystems, Foster City, CA). Clonal rearrangements detected at presentation were looked for at week 20.

RESULTS

Of 42 patients, 35 had a clonal population detectable at presentation; of these, seven had more than two clonal rearrangements; this latter group showed a similar disease-free survival (DFS) to the group as a whole. Thirty of 35 patients were analyzed before their second course of intensification therapy at week 20. At this point, nine of 30 had a detectable clonal rearrangement, eight (89%) of whom have since relapsed with a median DFS of 27.5 months. Of the rest of the group (n=21), in whom no clonal rearrangement was detectable, only six (21%) have relapsed.

CONCLUSION

Fluorescent IgH PCR at week 20 provides a sensitive and specific means to predict ultimate relapse (57% and 89%, respectively) and is a simple yet promising technique for the identification of patients at risk of poor outcome.
Bone mass after treatment for acute lymphoblastic leukemia in childhood.
Authors: Nysom K , Holm K , Michaelsen K F , Hertz H , Müller J , Mølgaard C
Published: February 2017

PURPOSE

To study bone mass after childhood acute lymphoblastic leukemia (ALL) and determine if reduced bone mass is related to previous therapy or endocrine status at follow-up.

PATIENTS AND METHODS

We studied 95 survivors of childhood ALL who were in first remission a median of 11 years (range, 3 to 23 years) after diagnosis and who had never been irradiated outside a cranial field. The bone mass was measured by dual-energy x-ray absorptiometry. The results were compared with data on 396 local controls.

RESULTS

Adjusted for sex and age, the mean whole-body bone mineral content (BMC) and bone mineral areal density (BMDA) were both significantly reduced (0.4 SDs less than the predicted mean value). This was mainly caused by reduced bone mass in the 33 participants who were aged 19 years or older at follow-up. In these young adults, the mean height for age, bone area for height, and BMC for bone area were all significantly reduced. This indicated that the reduced whole-body bone mass was caused by both reduced bone size and reduced size-adjusted bone mass. Reduced bone size was related to previous cranial irradiation. Reduced size-adjusted bone mass was not significantly related to age at diagnosis or at follow-up, length of follow-up, cranial irradiation, cumulative dose of methotrexate or corticosteroids, or endocrine status at follow-up.

CONCLUSION

The whole-body bone mass was reduced 11 years after diagnosis of childhood ALL. If these abnormalities remain, survivors of childhood ALL will have an increased risk for osteoporotic fractures later in life.
