Cytarabine and neurologic toxicity.
Authors: Baker W J , Royer G L , Weiss R B
Published: February 2017

Cytarabine is an effective drug in the treatment of certain hematologic malignancies and its common toxicities are myelosuppression and gastrointestinal disturbance. In the past decade, neurotoxicity has been an increasingly recognized cytarabine effect. Intrathecal (IT) cytarabine may result in myelopathy that is incompletely reversible. Combined IT drug and cranial irradiation may lead to necrotizing leukoencephalopathy. Intravenous (IV) therapy may cause a peripheral neuropathy that varies greatly in its severity. The high IV cytarabine doses now commonly used can cause seizures, cerebral dysfunction, or an acute cerebellar syndrome with an incidence up to 14%. Patient age (greater than 60 years) appears to be the most important risk factor, but drug dose/schedule, cumulative drug dose, renal and hepatic dysfunction, and concomitant use of neurotropic antiemetic agents may also influence the risk of neurotoxicity. A better understanding of the pathophysiology and pharmacology of such cytarabine-induced neuronal injury will allow this drug to be used with greater efficacy and safety.

Five hundred forty-three patients with completely resected malignant melanoma who were considered to have a significant risk of developing recurrent disease were randomized to one of four study groups. One group received levamisole 2.5 mg/kg on 2 consecutive days weekly for 3 years, a second group received bacillus Calmette-Guérin (BCG) for 3 years. A third group alternated 8-week courses of BCG and levamisole for 3 years and a fourth group underwent clinical assessment at the same frequency as the three treatment groups. The median duration of follow-up is 8.5 years. The percentage of reduction in the death rate and the recurrence rate in the treatment groups compared with the control group was calculated using the Cox proportional hazards model and adjusted for age, sex, and stage as covariants. The patients treated with levamisole were estimated to have a 29% reduction in both the death rate (P = .08) and the recurrence rate (P = .09) compared with patients receiving no further treatment. Fifty-five patients discontinued levamisole early because of gastrointestinal intolerance or arthralgia, myalgia, fever, and immune leukopenia. The patients treated with BCG alternating with levamisole experienced a 10% reduction in the death rate and a 6% reduction in the recurrence rate, and the patients treated with BCG alone experienced a 4% reduction in the death rate and a 3% increase in the recurrence rate compared with the control group. The degree of improvement experienced by the patients that were treated by levamisole is of sufficient magnitude to warrant further investigation of this dose of levamisole as adjuvant treatment in patients with melanoma.

Between 1981 and 1986, 200 consecutive patients with metastatic nonseminomatous testicular cancer were entered into the Swedish Norwegian Testicular Cancer (SWENOTECA) project from 14 hospitals. The treatment plan was four chemotherapy cycles (cisplatin, vinblastine, and bleomycin) followed by surgical resection of residual tumor masses. After a median observation time of 75 months, the overall 5-year survival rate was 82%. In a univariate analysis, the following parameters influenced the prognosis significantly: the extent of the disease (Medical Research Council [MRC] grouping); the prechemotherapy levels of serum alpha-fetoprotein (AFP), human chorionic gonadotropin (HCG), and lactate dehydrogenase (LDH); the patients' age; the presence of extrapulmonary hematogeneous metastases; and/or particularly large lymph node metastases. Patients fared better when more than 3 weeks elapsed between orchiectomy and start of chemotherapy as compared with those who were treated within this interval. The place of treatment (a large oncology unit v smaller units) also represented a significant prognostic factor for patients with large-volume (LV) and very-large-volume (VLV) disease combined. Multivariate analysis (Cox regression proportional hazards model) performed in all 193 assessable patients showed the following adverse prognostic factors: high-volume metastatic burden, age older than 35 years, prechemotherapy AFP greater than 500 micrograms/L and/or HCG greater than 1,000 U/L, and an interval between orchiectomy and start of chemotherapy of less than 3 weeks. The place of treatment also significantly influenced the final outcome. If patients with LV and VLV disease were combined, the presence of two of the following risk factors represented an additional prognostic factor: AFP greater than 1,000 micrograms/L, HCG greater than 10,000 U/L, liver metastases, brain metastases, bone metastases, retroperitoneal tumor greater than or equal to 10 cm, and mediastinal tumor greater than or equal to 5 cm.

Published: February 2017

In a prospective phase III multicenter trial, 213 patients with advanced measurable or nonmeasurable gastric cancer were randomized to receive methotrexate (MTX), fluorouracil (5-FU), and Adriamycin (doxorubicin; Farmitalia Carlo Erba, Milan, Italy) (FAMTX) or 5-FU, Adriamycin, and mitomycin (FAM). The results show a significantly superior response rate (41% v 9% [P less than .0001]), and survival (median, 42 weeks v 29 weeks [P = .004]) for FAMTX. There was a cumulative thrombocytopenia in FAM and not in FAMTX. The FAMTX protocol should be the reference treatment in future clinical trials that seek to improve the therapeutic outcome in advanced gastric cancer.

Published: February 2017

This report provides strong evidence for conducting a controlled randomized clinical trial of autologous bone marrow transplantation versus conventional chemotherapy in childhood neuroblastoma, which is disseminated beyond the intracavity nodes, and which is diagnosed in children older than 12 months of age. On the basis of two Pediatric Oncology Group (POG) studies, one a surgery plus conventional chemotherapy study (POG 8441) and the other an elective autologous transplant pilot protocol (POG 8340), there was no significant prognostic benefit of switching in remission from the surgery plus chemotherapy protocol to the transplant protocol (P = .91) or of switching in remission from the surgery plus chemotherapy protocol to any transplant (P = .75). The analysis is based on 116 patients achieving a complete or partial remission, 32 of whom received transplants on the pilot protocol, and 17 of whom received transplants outside the pilot protocol. While potential selection bias precludes cause-effect conclusions, these data strongly suggest that a large randomized trial of autologous bone marrow transplantation should be conducted before accepting this form of therapy as standard.

Published: February 2017

The study population included 136 patients with stage IA, IB, IIA, IIB, or IIIA1 Hodgkin's disease. The median follow-up is 7.5 years. Among the 30 patients with peripheral IA disease, all patients achieved a complete response (CR) with radiation therapy, and no patient has relapsed. Patients of other stages were randomized to receive radiation therapy or mechlorethamine, vincristine, procarbazine, and prednisone (MOPP). Among the 51 patients randomized to receive radiation therapy, 49 (96%) achieved complete remission, 17 (35%) have relapsed, and 10 (20%) have died. Fifty-two of the 54 (96%) assessable patients randomized to receive MOPP obtained CRs, seven (13%) have relapsed, and four (7%) have died. The projected 10-year disease-free survival of patients randomized to receive radiation therapy is 60%; for those randomized to receive MOPP, it is 86% (P2 = .009 in favor of MOPP). The projected 10-year overall survival for patients randomized to radiation therapy is 76%, and for MOPP-treated patients it is 92% (P2 = .051 in favor of MOPP). When the randomized patients with massive mediastinal disease or stage IIIA1 disease were excluded from the analysis, the disease-free (67% for radiation v 82% for MOPP) and overall survival (85% for radiation v 90% for MOPP) were not significantly different between the two arms. Subset analysis showed significant superiority of MOPP in the treatment of the following patient groups: stage IIIA1 or massive mediastinal disease, no B symptoms, initial erythrocyte sedimentation rate greater than 20 mm, four or more sites of disease, and younger than age 40 years. Preliminary analysis of this ongoing study shows that MOPP chemotherapy is at least as effective as radiation therapy in the treatment of the specific groups of early-stage Hodgkin's disease patients randomized. The final assessment of these two diverse treatment options will depend largely on the long-term survival and the incidence of early- and late-treatment complications for which patients are continuing to be observed.
Effective treatment of small-noncleaved-cell lymphoma with high-intensity, brief-duration chemotherapy.

Published: February 2017

Small-noncleaved-cell (SNC) lymphoma is a high-grade, biologically aggressive neoplasm notable for poor response to therapy, high relapse rate, and less than a 20% long-term survival. We treated 20 patients with SNC lymphoma with a novel chemotherapeutic regimen using intensive doses of chemotherapy at frequent intervals in the inpatient setting. All patients were previously untreated. Sixteen patients (80%) had stage IV disease. Most patients (95%) had at least one other characteristic associated with poor prognosis (bulky [greater than 10 cm] disease, multiple extranodal sites, poor performance status), and 85% had two or more characteristics associated with poor prognosis. Seventeen patients (85%) achieved a complete response (CR) to therapy, including all three patients with human immunodeficiency virus (HIV)-associated disease. There have been three relapses, all occurring less than 18 months after treatment, and two of three relapses occurred in patients who were unable to complete therapy. At a median follow-up of 29 months, 13 patients (65%) remain disease-free; the calculated 5-year actuarial disease-free survival is 60%. Toxicity, chiefly myelosuppression, was severe but manageable. There were two treatment-related deaths, both in elderly patients with poor performance status and advanced-stage disease. These data suggest that such a dose-intensive approach improves the response and survival of patients with SNC lymphoma.

From October 1984 to November 1987, 34 patients aged from 1 year 1 month to 7 years 7 months with resistant or relapsed neuroblastoma (NB) (group 1, 10 patients), unselected disseminated NB (group 2, 14 patients), or selected disseminated NB (group 3, 10 patients) received myeloablative therapy (MAT) followed by unpurged autologous bone marrow transplantation (ABMT) at the end of an intensive protocol, which included high-dose chemotherapy and surgery to the primary tumor. Median time from diagnosis to MAT and ABMT was 6 months (5 months from last relapse to MAT and ABMT in the relapsed patients). The MAT regimen included vincristine, fractionated total body irradiation (TBI), and melphalan. Seventeen patients were grafted in complete remission (CR), five in very good partial remission (VGPR), 10 in partial remission (PR), and two in progressive disease (PD). The acute toxic death rate was 2.9%. The overall progression-free survival was 29%. The median progression-free survival was 20 months for the 17 patients grafted in CR, 6 months for the five patients grafted in VGPR, and 12 months for the 10 patients grafted in PR.

Published: February 2017

Between 1984 and 1989, 159 patients presenting with advanced germ cell cancer were entered on a randomized clinical trial comparing the efficacy and toxicity of etoposide and bleomycin and either standard-dose cisplatin (20 mg/m2 daily for 5 days) or high-dose cisplatin (40 mg/m2 daily for 5 days). Of the 159 patients, 153 were assessable for toxicity and response. As expected, patients receiving the high-dose cisplatin regimen experienced significantly more neurotoxicity, ototoxicity, nausea and vomiting, and myelo-suppression. Four patients (3%) died related to therapy. Despite the toxicity encountered, dose intensity was maintained. Overall, 84% of patients in the high-dose arm received 80% or more of the projected dose of cisplatin, etoposide, and bleomycin; and 90% of patients on the standard-dose arm received 80% or more of the projected dose. Of the 76 eligible patients randomized to receive the high-dose cisplatin regimen, 52 (68%) became disease-free with chemotherapy alone or with subsequent resection of residual teratoma or cancer. Of the 77 patients randomized to the standard-dose arm, 56 (73%) became disease-free with chemotherapy alone or with surgery. Median follow-up is now 24 months. Eleven patients (three high-dose and eight standard-dose) relapsed from disease-free status. Overall, 74% of patients receiving the high-dose cisplatin regimen are alive, and 63% are continuously free of disease. Of the patients receiving the standard-dose cisplatin regimen, 74% are alive, and 61% are continuously free of disease. This randomized prospective trial in advanced germ cell cancer achieved dose intensity of the most active single agent in this disease. This dose intensity did not translate into an improved survival or cure. We conclude that dose escalation of cisplatin beyond standard doses results in excess toxicity with no accompanying therapeutic benefit.

Published: February 2017

A total of 59 eligible patients with localized Ewing's sarcoma of the pelvic and sacral bones were entered into a multimodal Intergroup Ewing's Sarcoma Study (IESS-II) (1978 to 1982) and compared with a historical control series of 68 patients entered into an earlier multimodal Intergroup Ewing's Sarcoma Study (IESS-I) (1973 to 1978). High-dose intermittent multiagent chemotherapy (vincristine, cyclophosphamide, Adriamycin [doxorubicin; Adria Laboratories, Columbus, OH], and dactinomycin) was given to all patients for 6 weeks before and for 70 weeks following local therapy. All patients who had a tumor biopsy or incomplete resection performed received a dose of 55 Gy to the tumor bed. With a median follow-up time of 5.5 years, two of 59 patients (3%) had a local recurrence, five patients (8%) had a local recurrence and metastases, and 17 patients (29%) developed metastases only. There was significant statistical evidence of an advantage in relapse-free survival (RFS) and survival (S) for patients on IESS-II versus IESS-I, P = .006 and P = .002, respectively. At 5 years, the comparison between IESS-II versus IESS-I was 55% versus 23% for RFS and 63% versus 35% for S.

We have conducted a phase I study with autologous monocytes activated ex vivo and administered intraperitoneally in nine patients with peritoneal carcinomatosis. Blood monocytes were collected by leukapheresis and then purified by counterflow elutriation (up to 10(9) cells, with a purity of greater than 90%). Ex vivo activation was obtained by incubating these cells with 1 micrograms liposomal MTP-PE/10(6) monocytes for 18 hours in hydrophobic culture bags at 37 degrees C in 5% carbon dioxide humidified air. The activated monocytes were then infused in the peritoneal cavity once a week for 5 consecutive weeks through an implanted peritoneal infusion system, Port-A-Cath (Pharmacia Deltec, St Paul, MN), on an intrapatient dose-escalating schedule (10(7) to 10(9) monocytes). No severe adverse reactions occurred. Toxicity was mild, the chief acute reactions being fever (27%), chills (13%), and abdominal pain (25%). None of the side effects led to dose reduction. No consistent change in hemostatic function, liver function, or renal function was observed. Significant increases in granulocyte counts, neopterine, and acute phase reactants (fibrinogen, C-reactive protein) occurred in the peripheral blood. In vitro monocyte activation was demonstrated by the relapse of procoagulant activity and monokines (interleukin-1 [IL-1], IL-6, and tumor necrosis factor-alpha [TNF alpha]) in the supernatants of cultured monocytes. Evidence for in vivo monocyte activation was provided by the increase of these monokines in the peritoneal fluids. Kinetic studies with indium-111 (111In)-labeled activated autologous monocytes in five patients suggest that these infused monocytes may remain in the peritoneal cavity for up to 7 days. This locoregional immunotherapeutic approach seems to be encouraging in view of adjuvant therapeutic modality in ovarian cancer patients with minimal residual intraabdominal disease following second-look laparotomy.

Eighty-three patients (median age, 56 years and Karnofsky performance status greater than or equal to 70) were treated with carboplatin (Carbo) and fluorouracil (5Fu) for stage III and IV head and neck squamous cell carcinoma (HNSCC). 5Fu (1 g/m2/d) was administered from day 1 to 4 by continuous infusion. Carbo was given on day 1 and, in order to evaluate its maximum-tolerated dose (MTD), the dose level was progressively increased from 250 mg/m2 to 450 mg/m2. The effectiveness of this association and its potential role in local control were also evaluated. Three patients received Carbo at a dose of 250 mg/m2, 13 received 300 mg/m2, one received 330 mg/m2, 12 received 350 mg/m2, six received 375 mg/m2, 26 received 400 mg/m2, 18 received 420 mg/m2, and four received 450 mg/m2. Two (13 of 83) or three courses (64 of 83), repeated every 4 weeks, were administered. The overall (primary tumor and node) response and complete response (CR) rates were 33% and 14%, respectively. For primary tumor, the response rate (RR) was 57% with 32% CR and 18% pathologic complete response (PCR); the RR was higher for patients with oropharyngeal tumor (76%, P = .037) and for patients treated with Carbo greater than or equal to 350 mg/m2 (65%, P = .02); the tumor size (T1 + T2 v T3 + T4) was a good prognostic factor for RR (90% v 46%, P = .001), CR (65% v 20%, P less than .001), and PCR (45% v 8%, P less than .001). For nodes, the RR was 33% with 11% CR. Grade 3-4 neutropenia and thrombocytopenia were experienced by 17% and 28% of the patients treated with 420 mg/m2 of Carbo and by 50% of the patients treated with 450 mg/m2. The MTD can be fixed at 420 mg/m2 and the proposed dose at 400 mg/m2. Thirty-eight patients were treated with surgery plus radiotherapy, 33 with radiotherapy alone, and seven with surgery alone. The median follow-up is 12 months. The 18-month disease-free survival (DFS) is 78% for overall complete responders and 39% for the others (P = .04). There is no primary tumor recurrence among the 12 patients with a primary tumor PCR treated by radiotherapy alone for tumor control (median follow-up, 17.3 months). The association of Carbo-5Fu is a safe induction chemotherapy regimen for HNSCC. The proposed dose of Carbo for future treatment is 400 mg/m2.(ABSTRACT TRUNCATED AT 400 WORDS)
Objective antitumor activity of acivicin in patients with recurrent CNS malignancies: a Southwest Oncology Group trial.

Published: February 2017

Acivicin (AT-125) is a glutamine antagonist with dose-limiting, schedule-dependent CNS toxicity and predictable CSF penetration after intravenous administration. Because of these properties, a trial in CNS malignancies was initiated. Thirty-two patients with recurrent or residual malignant astrocytomas were treated with AT-125. The majority of patients had glioblastoma multiforme (24) and had received prior nitrosoureas (21). The median age was 50 years, and Southwest Oncology Group (SWOG) performance status was 2. The major determinant of response was based upon radiologic criteria using computed tomographic (CT) scanning and/or magnetic resonance imaging (MRI) scans. The tumor mass was measured in two perpendicular planes, which yielded the largest cross-sectional area. Standard solid tumor criteria for response were used. All responding patients also had a stable or tapered dose of corticosteroids with stable or improved performance status and neurologic examination. There were four objective responses (12%): one complete remission (3 1/2+ years) and three partial remissions (57, 86, and 322 days). Two patients had improvement in disease that did not meet requirements for a partial remission. Toxicity was mild and primarily consisted of nausea, vomiting, and lethargy. Two patients were removed from study due to neurotoxicity (depression and hallucinations). The strict response criteria used in this trial were not those that have been used in testing other active agents such as carmustine (BCNU). We conclude that AT-125 has objective antitumor activity in malignant astrocytomas and warrants further study.

Published: February 2017

Sixty-two patients with advanced-stage Hodgkin's disease and a median age of 12 years (range, 3 to 22 years) were treated with four cycles of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) alternating with four cycles of doxorubicin, vinblastine, bleomycin, and dacarbazine (ABVD) followed by low-dose radiotherapy (RT). We determined the feasibility, immediate safety, and rapidity of response of patients to this regimen, as well as the relationship between prognostic factors and the rate of complete remission (CR), event-free survival (EFS), and overall survival. Therapy was well tolerated, and the major toxicity was hematopoietic. At the end of chemotherapy, 54 of 62 patients (87%) were in CR by clinical restaging, with a biopsy of residual disease where necessary. The actuarial 3-year EFS is 77% (SE, 11%), with a median follow-up of 35 months, and the survival is 91% (SE, 7%). With respect to EFS, female patients and those with stage II or III disease fared statistically better than males and patients with stage IV disease, respectively. Six patients have died: three of progressive Hodgkin's disease, one of secondary acute myelocytic leukemia (AML), one of secondary non-Hodgkin's lymphoma (NHL), and one of overwhelming bacterial sepsis. The Pediatric Oncology Group (POG) is currently engaged in a randomized study of these eight cycles of chemotherapy with and without RT to assess the role of RT in achieving comparable results.
Prognosis in T2N0M0 stage I breast carcinoma: a 20-year follow-up study.
Authors: Rosen P P , Groshen S , Kinne D W
Published: February 2017

In a study of prognosis in node-negative breast carcinoma, we investigated 293 T2N0M0 patients treated by mastectomy and axillary dissection with a median follow-up of 19.8 years. The probability of surviving 20 years considering all causes of death was 41.3% +/- 3.0%. Recurrence-free survival (Kaplan-Meier estimate) was 68.6% +/- 3% at 10 years and 63.2% +/- 3.1% at 20 years. The estimated probability of cure determined by the method of Brinkley and Haybittle was 63% (95% confidence interval [Cl], 55% to 72%). Prognosis was related to primary tumor size with the best separation (P = .06) when tumors from 2.1 to 3.0 cm (33% chance of recurrence at 20 years) and from 3.1 to 5.0 cm (44% chance of recurrence at 20 years) were compared. The histologic tumor type was prognostically important. Recurrence at 20 years was not significantly different for patients with invasive duct (34%) and lobular (42%) carcinoma. Women with special types (medullary, mucinous, papillary, etc) of carcinoma had a 25% chance of recurrence. Subsequent contralateral breast carcinoma was diagnosed in 29 patients, and four of these were fatal, accounting for only 4.6% of breast carcinoma deaths. Thirty-two patients (10.9%) developed a nonmammary malignant neoplasm (NMMN) after the ipsilateral breast carcinoma, and 69% of these lesions were fatal. Although the chances of recurrence at 20 years related to tumor size and type did not differ statistically in the series, there were trends that suggest that T2N0M0 patients can be stratified into recurrence risk groups based on tumor size and histologic type. These factors should be taken into consideration in the design and analysis of clinical adjuvant therapy trials. Measures for the early detection of common NMMNs should be included in the routine follow-up of T2N0M0 breast carcinoma patients.
Lack of efficacy of high-dose leucovorin and fluorouracil in patients with advanced pancreatic adenocarcinoma.

Published: February 2017

Leucovorin potentiates the cytotoxicity of fluorouracil (5-FU) in experimental tumor systems and appears to enhance the effectiveness of 5-FU in patients with colon cancer. Twenty-two eligible patients (18 previously untreated) with advanced pancreatic adenocarcinoma were treated in a phase II trial of leucovorin 500 mg/m2/d for 6 days by continuous intravenous infusion with 5-FU 370 mg/m2/d by rapid intravenous injection on 5 consecutive days, beginning 24 hours after initiation of leucovorin infusion. Among the 20 assessable patients, there were no complete or partial regressions, although there was one minor response lasting 4 months. Three patients had stable disease for 5, 20, and 21 months, respectively. Median survival was 10 weeks. Toxicity was predominantly mucosal; stomatitis grade 2 or worse was seen in five patients, and diarrhea grade 2 or worse was seen in four. Hospitalization for toxicity was necessary in four previously untreated patients and three previously treated patients. The median WBC nadir was 4.6 (range, 1.4 to 9.6) x 10(3)/microL, and the median platelet nadir was 147.0 (range, 69.0 to 240.0) x 10(3)/microL. This combination of leucovorin and 5-FU did not demonstrate meaningful therapeutic activity in patients with adenocarcinoma of the pancreas and was associated with moderate to severe toxicity. It should not be considered a standard treatment for patients with this disease.

Published: February 2017

PURPOSE

Because there is a compelling need to develop new agents for intrathecal use, we investigated the safety, efficacy, and CSF pharmacokinetics of diaziquone (AZQ) following intrathecal administration in patients with refractory meningeal malignancies.

PATIENTS AND METHODS

Thirty-nine patients received 45 courses of intrathecal AZQ. Two schedules were studied; twice-weekly administration of a 1- or 2-mg dose and "concentration times time" (C x T) administration of 0.5 mg every 6 hours for three doses, administered once weekly.

RESULTS

Dose-limiting toxicity consisting of headache, nausea, or vomiting occurred in only three patients and only at the 2-mg, twice weekly dose. The schedules of 1 mg twice-weekly and 0.5 mg every 6 hours for three doses were well tolerated. Thirty-seven courses were assessable for response. The overall response rate was 62%. Complete responses (CRs) occurred in 14 of 37 courses (38%) and partial responses (PRs) occurred in nine of 37 courses (24%). Among patients with meningeal leukemia, CRs were observed in 11 of 26 courses (42%) and PRs in nine of 26 courses (35%). There was no difference in response rate related to dose or schedule. The pharmacokinetic behavior of intrathecally administered AZQ was characterized by biexponential disappearance from ventricular CSF, with mean half-lives of 18.2 and 78.6 minutes. The mean clearance rate was 0.37 mL/min.

CONCLUSION

Intrathecal AZQ is safe, well tolerated, and highly active against refractory meningeal malignancies.

PURPOSE

Fludarabine (2-fluoro-arabanoside-monophosphate) is a new antimetabolite chemotherapeutic agent. We performed a multicenter, phase II study of this drug in previously treated patients with refractory or relapsed non-Hodgkin's lymphoma (NHL) to determine its response rate by histologic classification.

PATIENTS AND METHODS

Sixty-two assessable patients were given 18 mg/m2 by intravenous (IV) bolus injection daily for 5 days, every 28 days. Forty-eight percent had previously had one chemotherapy regimen, and the remainder had had two regimens; 42% had had radiation.

RESULTS

Patients received 273 cycles of fludarabine chemotherapy, with a median of two cycles and ranging up to 25 cycles. Sixty patients were assessable for response, including nine complete responses (CRs; 15%) and nine partial responses (PRs; 15%). The response rate for patients with lower-grade histology was 52% (13 of 25); the greatest response rate was seen in those with follicular small cleaved-cell lymphoma, including seven of 11 treated. Five responders remain in unmaintained remission; the median survival of responders is greater than 30 months. Toxicity included mild neutropenia and a 10% incidence of grade 3 neurologic toxicity with occasional reversible visual and auditory changes.

CONCLUSION

Fludarabine is active in patients with previously treated NHL (particularly low-grade histologies). Future studies will examine its activity in combination with other chemotherapeutic agents in previously untreated patients.

Published: February 2017

PURPOSE

Despite substantial progress in the treatment of acute myeloid leukemia (AML), fewer than 25% of patients survive free of leukemia for more than 5 years without allogeneic bone marrow transplantation (BMT). In this study we analyzed the results of one or more cycles of high-dose cytarabine-based consolidation chemotherapy as compared with allogeneic BMT in first remission.

PATIENTS AND METHODS

The results in 28 adult patients, aged 16 to 45 years, who underwent a closely HLA-matched BMT for AML in first remission were compared with those in 54 consecutive, age-matched, adult patients treated with one or more cycles of high-dose, cytarabine-based consolidation chemotherapy.

RESULTS

After a median follow-up of 4 years, the actuarial risk of leukemic relapse was considerably lower in the transplant group than in the group treated with consolidation chemotherapy (32% +/- 26% v 60% +/- 14%; P = .05). Treatment-related mortality, however, was much higher in the group treated with BMT (32% v 6%, P = .002). The actuarial disease-free survival at 5 years was not significantly different for the two groups (45% +/- 24% v 38% +/- 14%).

CONCLUSIONS

Our results show that BMT in first remission AML did not offer a disease-free survival advantage over intensive postremission consolidation chemotherapy. Larger studies are needed to identify patients who might benefit most from BMT.
High-dose recombinant tumor necrosis factor alpha in combination with interferon gamma and melphalan in isolation perfusion of the limbs for melanoma and sarcoma.
Authors: Lienard D , Ewalenko P , Delmotte J J , Renard N , Lejeune F J
Published: February 2017

PURPOSE

To determine the toxicity and the therapeutic efficacy of the combination of the recombinant tumor necrosis factor alpha (rTNF alpha), recombinant interferon gamma (rIFN-gamma), and melphalan, we designed a protocol using isolation limb perfusion (ILP) with hyperthermia for in-transit metastases of melanoma and recurrent sarcoma. The triple combination was chosen because of the reported synergistic antitumor effect of rTNF alpha with IFN-gamma and of rTNF alpha with alkylating agents.

PATIENTS AND METHODS

Twenty-three patients received a total of 25 ILPs with the triple combination. There were 19 females and four males with either multiple progressive in-transit melanoma metastases of the extremities (stage IIIa or IIIab; 19 patients) or recurrent soft tissue sarcoma (five). The rTNF alpha was injected as a bolus in the arterial line, and total dose ranged between 2 and 4 mg, under hyperthermic conditions (40 degrees C to 40.5 degrees C) for 90 minutes. The rIFN-gamma was given subcutaneously (SC) on days -2 and -1 and in the perfusate, with rTNF alpha at the dose of 0.2 mg. Melphalan (Alkeran; Burroughs Wellcome Co, London, England) was administered in the perfusate at 40 micrograms/mL.

RESULTS

Toxicity observed during three ILPs in a pilot study with rTNF alpha included only two severe toxicities: one severe hypotension with tachycardia and transient oliguria and one moderate hypotension for 4 hours followed by severe kidney failure with complete recovery on day 29. In all 18 ILPs performed in the triple combination protocol, the patients received continuous infusion dopamine at 3 micrograms/kg/min from the start of ILP and for 72 hours and showed only mild hypotension and transient chills and temperature. Regional toxicity attributable to rTNF alpha was minimal. There have been 11 cases with hematologic toxicity consisting of neutropenia (one grade 4 and one grade 3) and neutropenia with thrombocytopenia (one grade 4 and three grade 2). Twelve patients had been previously treated with melphalan in ILP (11) or with cisplatin (one). The 23 patients are assessable: there have been 21 complete responses (CRs; range, 4 to 29 months; 89%), two partial responses (PRs; range, 2 to 3 months), and no failures. Overall disease-free survival and survival have been 70% and 76%, respectively, at 12 months. In all cases, softening of the nodules was obvious within 3 days after ILP and time to definite response ranged between day 5 and 30.

CONCLUSION

This preliminary analysis of a phase II study suggests that high-dose rTNF alpha can be administered with acceptable toxicity by ILP with dopamine and hyperhydration. Tumor responses can be evidenced in melanoma and sarcoma. Furthermore, combination of rTNF alpha, rIFN-gamma, and melphalan seems to achieve high efficacy with minimal toxicity, even after failure of prior therapy with melphalan alone.
The Second Medical Research Council study of prognostic factors in nonseminomatous germ cell tumors. Medical Research Council Testicular Tumour Working Party.
Authors: Mead G M , Stenning S P , Parkinson M C , Horwich A , Fossa S D , Wilkinson P M , Kaye S B , Newlands E S , Cook P A
Published: February 2017

PURPOSE

To assess prognostic factors in a large population of patients with metastatic nonseminomatous germ cell tumors (NSGCT) arising in gonadal or extragonadal sites.

PATIENTS AND METHODS

Data from 795 patients treated with chemotherapy between 1982 and 1986 in 13 centers were analyzed. Particular emphasis was placed on exact tumor measurements (eg, size of nodal masses, number of lung metastases), and the diagnostic pathology was also reviewed. Cox regression analysis was performed on these data. The patients were treated with a variety of cisplatin-containing chemotherapy regimens, 86% of which included etoposide.

RESULTS

With median follow-up of 45 months, overall 3-year survival is 85%. The independently adverse features proved to be (1) the presence of liver, bone, or brain metastases; (2) raised marker levels (alpha-fetoprotein [AFP] level greater than 1,000 kU/L or beta subunit of human chorionic gonadotropin [HCG] greater than 10,000 IU/L [corrected]); (3) the presence of a mediastinal mass greater than 5 cm in diameter; (4) the presence of 20 or more lung metastases; (5) increasing age; and (6) absence of undifferentiated teratoma (embryonal carcinoma) or fibrous tissue from the primary tumor.

CONCLUSIONS

The first four factors were used to define a simple prognostic classification. A good-prognosis group having none of these features comprised 67% of our patient population and had a 3-year survival of 93%. The remaining 33% of patients having at least one of these features had a 3-year survival rate of 68%. These patient groups are currently the subjects of international randomized clinical trials.
Serum sialyl Tn as an independent predictor of poor prognosis in patients with epithelial ovarian cancer.
Authors: Kobayashi H , Terao T , Kawashima Y
Published: February 2017

PURPOSE

Monoclonal antibody (moAB) TKH-2 directed to the tumor-associated O-linked sialyl 2-6-alpha-N-acetylgalactosaminyl (sialyl Tn; STN) epitope was generated by immunization with ovine submaxillary mucin (Kjeldsen et al, Cancer Res 48:2214-2220, 1988). We investigated whether circulating serum levels of STN antigen might influence the prognosis of patients with ovarian cancer.

PATIENTS AND METHODS

Serum samples were obtained from 126 healthy nonpregnant women, 157 patients with benign gynecologic disease, and 89 patients with histologically proven epithelial ovarian cancer. Circulating serum STN-antigen concentrations (U/mL) were determined by a competitive radioimmunoassay kit (Otsuka Assay Laboratories, Tokushima, Japan) in a one-step procedure.

RESULTS

Serum antigen levels were elevated in 48.3% of the patients. The levels of STN antigen were significantly higher in the sera of patients with cancer when compared with levels in benign and healthy controls (P less than .05). The 5-year survival rate for patients with STN-negative (serum STN levels less than 50.0 U/mL) versus STN-positive (greater than or equal to 50 U/mL) tumors was 76.9% versus 10.8%, respectively (P less than .05). The progression-free interval (PFI) at 5 years was 51.9% versus 5.4%, respectively (P less than .05). The overall survival probability and PFI were worse in patients with STN-positive sera. Multivariate regression analysis revealed that stage, residual tumor size, positive STN, performance status, and histologic grade were the five important variables for predicting overall survival.

CONCLUSION

We conclude that a positive STN-antigen level in sera is an independent predictor of poor prognosis in ovarian cancer.

Authors: Margolin K A , Doroshow J H , Akman S A , Leong L A , Morgan R J , Somlo G , Raschko J , Pereira C , Yonemoto L , Ahn C
Published: February 2017

PURPOSE

To evaluate the antitumor activity of combination cisplatin (CDDP) and alpha-interferon (alpha-IFN) in advanced, measurable metastatic melanoma.

PATIENTS AND METHODS

Adult patients with metastatic melanoma were required to have bidimensionally measurable lesions and a Karnofsky performance status > or = 60%. Serum creatinine < or = to 1.5 mg/dL, creatinine clearance > or = 60 mL/min, adequate organ and bone marrow function, and radiologic proof of the absence of brain metastases were required. CDDP 40 mg/m2 intravenously (IV) on day 1 and day 8, and alpha-IFN 3 million units/m2 subcutaneously on days 1 to 5 and 8 to 12 were administered every 3 to 4 weeks.

RESULTS

Forty-two patients were entered onto this phase II trial and were assessable for response and toxicity. Three patients achieved complete responses (CRs) that lasted 31+, 5, and 8+ months. Seven patients had partial responses (PRs) and a median response duration of 4.4 months. The overall objective response rate was 24% (95% confidence interval, 12% to 39%). Toxicities were mild. Only 11% of the courses required dose reduction of alpha-IFN, and three of 128 courses required CDDP dose reduction for reversible nephrotoxicity.

CONCLUSION

The combination of moderate-dose CDDP and alpha-IFN as administered in this schedule is well tolerated and possesses encouraging activity in metastatic melanoma.
Breast cancer in patients irradiated for Hodgkin's disease: a clinical and pathologic analysis of 45 events in 37 patients.
Authors: Yahalom J , Petrek J A , Biddinger P W , Kessler S , Dershaw D D , McCormick B , Osborne M P , Kinne D A , Rosen P P
Published: February 2017

PURPOSE

To characterize the clinical and pathologic features of patients who developed breast cancer (BC) after treatment for Hodgkin's disease (HD). Recent epidemiologic studies have shown that women who are cured of HD have an increased risk of developing BC.

PATIENTS AND METHODS

The clinical data, mammograms, and pathologic specimens of 37 women who developed 45 BCs (eight bilateral events), and had a prior history of treatment for HD were analyzed.

RESULTS

The median age at diagnosis of HD was 27 years (range, 11 to 60). All patients received radiotherapy (RT) to the upper part of their body, and 10 also had chemotherapy for HD. The median interval from the treatment of HD to the diagnosis of BC was 15 years (range, 8 to 34). The median age at diagnosis of BC was 43 years (range, 27 to 75), 41% of patients were 39 years old or younger. Most mammograms (81%) showed abnormal findings of mass and/or microcalcifications. Of the eight patients (22%) with bilateral tumors, four were synchronous and four were metachronous. Involvement of the medial half of the breast occurred more frequently than in patients with primary BC (39% and 21%, respectively; P < .002). But, the histologic types, grades, presence of lymphocytic reaction, and lymphatic invasion were similar to those observed in 935 primary BC patients who were previously analyzed at our center. The 6-year actuarial relapse-free survival (RFS) for node-negative BC after HD was 85%. Node-positive patients had a significantly lower RFS of 33% (P = .002).

CONCLUSIONS

In comparison to patients with primary BC, patients who develop BC after HD are more likely to be younger, have bilateral disease, and have their tumors more frequently involve the medial half of the breast. Pathologic characteristics, nodal involvement, and prognosis are similar to those of primary BC. BC in women who were treated for HD is becoming an increasing problem, as more patients cured of HD reach a follow-up time of 10 to 15 years. Breast examination and mammography at an early age should be part of the follow-up program for women who are cured of HD.
Phase I/II study of iodine 131 metaiodobenzylguanidine in chemoresistant neuroblastoma: a United Kingdom Children's Cancer Study Group investigation.
Authors: Lashford L S , Lewis I J , Fielding S L , Flower M A , Meller S , Kemshead J T , Ackery D
Published: February 2017

PURPOSE

The goal of this study was to evaluate the toxicity of iodine 131 metaiodobenzylguanidine (mIBG) in metastatic neuroblastoma.

PATIENTS AND METHODS

A multicenter phase I study of 131I mIBG has been undertaken by the United Kingdom Children's Cancer Study Group (UKCCSG) in children with advanced chemoresistant neuroblastoma. Activity prescription was based on a prescribed whole-body radiation dose, which was established for individual patients by performing an initial tracer investigation with 75 MBq of 131I mIBG. An activity was derived from this pharmacokinetic study that would deliver an initial whole-body-absorbed radiation dose of 1 Gy. Subsequent dose escalations were based on observed toxicity.

RESULTS

Twenty-five patients, aged 1 to 10 years, were treated with prescribed whole-body dose levels of 1.0 Gy (n = 2), 2.0 Gy (n = 13), and 2.5 Gy (n = 10). This necessitated administration of 2.4 to 12.1 GBq of activity. Hematologic, hepatic, kidney, and adrenal toxicity were observed, with bone marrow suppression being the principal dose-limiting toxicity. Bone marrow toxicity increased with prescribed whole-body-absorbed radiation dose, with 80% of patients developing grade 3 or 4 thrombocytopenia at a prescribed whole-body radiation dose of 2.5 Gy. Objective evidence of tumor response was seen in soft tissue (primary or nodal disease), bone, and bone marrow, with an overall response rate of 33% (partial response, n = 8; static disease, n = 9; progressive disease, n = 7).

CONCLUSIONS

This study has established an effective method of activity prescription that predicts subsequent toxicity, with the maximally tolerated dose being sufficient activity to deliver a whole-body-absorbed radiation dose of 2.5 Gy. The objective response rate is comparable to other single agents in chemoresistant neuroblastoma and suggests that 131I mIBG may be a useful method for targeting radiotherapy in metastatic neuroblastoma.
