A promising interferon plus four-drug chemotherapy regimen for metastatic melanoma.
Authors: Pyrhönen S , Hahka-Kemppinen M , Muhonen T
Published: February 2017

PURPOSE

The goal of this study was to determine the therapeutic efficacy and toxicity of a four-drug chemotherapy regimen combined with natural leukocyte interferon alfa (IFN-alpha) for metastatic melanoma.

PATIENTS AND METHODS

Between December 1988 and December 1991, 48 consecutive unselected patients with metastatic melanoma were entered onto this phase II study. Forty-five of these patients were assessable for response and 46 for toxicity. The four-drug chemotherapy regimen was as follows: dacarbazine (DTIC) 200 mg/m2 days 1 to 5, vincristine 1 mg/m2 days 1 and 4, bleomycin 15 mg days 2 and 5 intravenously (IV), and lomustine (CCNU) 80 mg day 1 orally. IFN-alpha, initiated day 8, was administered 3 x 10(6) IU/d, subcutaneously (SC) for 6 weeks, followed by 6 x 10(6) IU three times per week. A small protocol modification was adopted from the 21st patient onwards whenever there was more than 2 months' stabilization or progression with the original protocol: IFN therapy was split into 2-week treatment periods interrupted by a 2-week rest period.

RESULTS

Among the 45 assessable patients, the objective response rate was 62% (95% confidence limit, 48 to 77); six patients (13%) achieved a complete response (CR) and 22 (49%) a partial response (PR). Metastases in such sites as liver also responded favorably (one CR, six PR, one stable disease [SD], two progressive disease [PD]). After splitting IFN therapy for nonresponders, in two patients PD and in another two patients SD changed into regression. Three of the six patients with a CR have suffered a relapse, but the other three have been off treatment for 7, 18, and 31 months without recurrence. Most of the symptomatic patients also experienced rapid relief of symptoms. Overall toxicity of this mainly outpatient regimen seemed to be acceptable. One patient died of a septic fever with grade 4 leukopenia and thrombocytopenia. The most frequent side effects were transient fever, nausea/vomiting, fatigue, and grade I/II hematologic toxicity.

CONCLUSION

Results demonstrate a remarkably high response rate in combining IFN-alpha and four chemotherapeutic agents. The apparent schedule-dependency of responses must be further explored in a controlled phase III study.

Published: February 2017

PURPOSE

A clinical trial for patients with gastric cancer amenable to curative resection was undertaken to determine feasibility and response to preoperative systemic chemotherapy followed by postoperative intraperitoneal (IP) chemotherapy.

METHODS AND MATERIALS

Thirty-eight patients with resectable gastric tumor received two cycles of protracted intravenous (IV)-infusion fluorouracil (5FU), 200 mg/m2/d, for 3 weeks with weekly IV leucovorin 20 mg/m2 and IV cisplatin 100 mg/m2 days 1 and 29. Resection of the gastric tumor followed within 3 weeks of completion of systemic chemotherapy. Those who had all visible tumor removed with clear margins received two cycles of IP floxuridine 3,000 mg (total dose) per day for 3 days and IP cisplatin 200 mg/m2 with IV sodium thiosulfate on the fourth day of IP therapy.

RESULTS

Thirty-seven of 38 patients (97%) received two cycles of systemic chemotherapy. Thirty-five of 38 patients (92%) underwent laparotomy for gastric tumor resection. Thirty-three patients (87%) had gastric resections performed; 29 (76%) had all visible tumor removed with microscopically negative margins. No operative mortality was encountered. Twenty-six patients (68%) received IP treatment. IV neoadjuvant treatment was well tolerated and resulted in 68% of the patients reporting improvement in abdominal pain, 45% objective remissions by computed tomography (CT), 38% objective remissions by gastroscopy and biopsy, and 8% had complete surgical pathologic response. Neutropenic sepsis during the IP treatment phase contributed to the only treatment-related death. Four of 29 completely resected patients (14%) have had tumor recurrence. The median follow-up time of patients remaining alive is now 19 months. The median survival for 38 patients entered onto this protocol has not been reached at 17+ months.

CONCLUSION

This novel approach to the treatment of adenocarcinoma of the stomach is feasible. The neoadjuvant systemic therapy results in significant primary tumor regression. The determination of whether systemic or IP components of the program contribute to decreased recurrence or increased survival awaits a prospectively randomized clinical trial.

There were several production errors in the report by Etienne et al, "Pharmacokinetics and Pharmacodynamics of Medroxyprogesterone Acetate in Advanced Breast Cancer Patients," published in the July 1992 issue (J Clin Oncol 10:1176–1182, 1992). In the abstract (p 1176), the abbreviation "Css minutes" should have been "Css min" for minimum steady-state concentration. The P value for the second footnote to Table 2 (p 1178) should have been ".99." In the Discussion section, the fourth sentence of the second paragraph (p 1180) should have read: "As concerns the 70 patients who received 1,000 mg/d orally, MPA concentrations ranged from 10 to 269 ng/mL (Fig 1)."

Published: February 2017

PURPOSE

The Pediatric Oncology Group (POG) conducted a randomized phase II study to evaluate the activity of carboplatin and iproplatin in children with progressive or recurrent brain tumors.

PATIENTS AND METHODS

The study was designed to evaluate the activity of these agents and to compare the toxicities associated with their use. Treatment consisted of carboplatin 560 mg/m2 at 4-week intervals or iproplatin 270 mg/m2 at 3-week intervals.

RESULTS

The major toxicity observed was myelosuppression, particularly thrombocytopenia, for both agents. Ototoxicity (grade 1 or 2) was seen in 2.5% of patients treated with carboplatin and 1.3% of patients treated with iproplatin. The majority of patients with low-grade astrocytic neoplasms treated with carboplatin (nine of 12 patients) or iproplatin (eight of 12 patients) demonstrated tumor response or prolonged stable disease that persisted off-therapy. The duration of stable disease produced by carboplatin was particularly striking, ranging from 2 months to 68 + months (median, 40 + months). Neither drug demonstrated appreciable activity in the treatment of medulloblastoma (two of 26 responses to carboplatin, one of 14 responses to iproplatin), ependymoma (two of 17 responses to carboplatin, none of seven responses to iproplatin), high-grade glioma (two of 19 responses to carboplatin, one of 14 responses to iproplatin), or brain-stem tumors (one of 23 responses to carboplatin, none of 14 responses to iproplatin).

CONCLUSION

Carboplatin is active against low-grade gliomas. Further evaluation of the role of carboplatin in the preirradiation treatment of children with low-grade gliomas of the optic pathway is currently underway in a clinical trial.
Phase I-II study of high-dose epirubicin in advanced non-small-cell lung cancer.
Authors: Feld R , Wierzbicki R , Walde P L , Shepherd F A , Evans W K , Gupta S , Shannon P , Lassus M
Published: February 2017

PURPOSE

A phase I multicenter trial was performed to determine the maximum-tolerated dose (MTD) of epirubicin, given on 3 consecutive days every 3 weeks to previously untreated patients with advanced non-small-cell lung cancer (NSCLC).

PATIENTS AND METHODS

After appropriate staging and a baseline multiple-gated angiogram (MUGA) scan, at least four patients were entered at each dose level, starting at 35 mg/m2 of epirubicin given intravenously (IV) daily for 3 days (105 mg/m2) and escalating by 5 mg/m2 per injection in each dose level (15 mg/m2 per course). Epirubicin was administered up to a maximum dose of 60 mg/m2/d for 3 days (180 mg/m2). The MTD was determined to be 55 mg/m2/d for 3 days (165 mg/m2) after treating a total of 35 (33 assessable) patients. Nadir granulocyte counts and associated febrile episodes comprised the dose-limiting toxicity, but there were no treatment-related deaths. A phase II trial was performed using a dose of 50 mg/m2/d for 3 days (150 mg/m2) every 3 weeks with no dose escalation, but with dose reduction for toxicity as required. A total of 30 patients were entered onto this phase of the study.

RESULTS

The major toxicity, as in the phase I trial, was neutropenia with five febrile episodes, again with no treatment-related deaths. An overall response rate of 12 of 63 (19%) was noted in the combined patient population of the phase I-II trial, with 95% confidence intervals of 10% to 31%. When the response rate was analyzed by histology, only one of 17 (6%) patients with squamous histology, as compared with 11 of 46 (24%) with non-squamous histology, responded, but this did not reach statistical significance (P = .15).

CONCLUSIONS

High-dose epirubicin is tolerable and is an active single agent in NSCLC. It should be combined with relatively nonmyelosuppressive agents such as cisplatin to try to obtain higher response rates and extend the survival in this disease.
Concomitant administration of recombinant human interleukin-2 and recombinant interferon alfa-2A: an active outpatient regimen in metastatic renal cell carcinoma.
Authors: Figlin R A , Belldegrun A , Moldawer N , Zeffren J , deKernion J
Published: February 2017

PURPOSE

A phase II trial of interleukin-2 (IL-2) and interferon alfa (IFN-alpha) in metastatic renal cell carcinoma (RCCa) was conducted. A lower dosage of IL-2 was given via continuous intravenous (IV) infusion, a route with documented tumor activity associated with less toxicity, with the purpose of improving the therapeutic index of this treatment in an outpatient setting.

PATIENTS AND METHODS

Thirty patients with metastatic RCCa were treated with the combination of IL-2 and IFN-alpha-2A. IL-2 was administered on days 1 through 4 of each treatment week, as a continuous IV infusion at a dose of 2 x 10(6) U/m2/d. IFN-alpha-2A was administered intramuscularly or subcutaneously on days 1 and 4 of each treatment week, at a dose of 6 x 10(6) U/m2/d. One treatment course included 4 weeks of treatment followed by a 2-week rest. Patients received therapy as outpatients except for the first 4 days of treatment, cycle 1 only. All patients were assessable for toxicity and response assessment. A total of 105 courses of therapy were administered, 51% at full dose.

RESULTS

Sixteen patients experienced toxicities resulting in dosage modification. The major treatment-limiting toxicities were gastrointestinal, neurologic, and fatigue. Nine patients (30%) had partial remissions (PRs) with a median duration of responses of 12+ months. The median time to response was 11 weeks. Two partial responders whose sites of metastatic disease were renal fossa and mediastinal lymph nodes (LN), respectively, were found to have achieved a pathologic complete remission (pCR) after surgery. A third patient with a pCR of axillary LN was rendered into a surgical complete remission (sCR) with salvage nephrectomy. Median survival of patients obtaining a PR has not been reached with a median follow-up time of 19+ months.

CONCLUSION

IL-2 and IFN-alpha-2A is well tolerated in the outpatient treatment setting and demonstrates significant clinical activity against RCCa.
Competing events determining relapse-free survival in limited small-cell lung carcinoma. The French Cancer Centers' Lung Group.
Authors: Arriagada R , Kramar A , Le Chevalier T , De Cremoux H
Published: February 2017

PURPOSE

We report results in terms of relapse-free survival (RFS), obtained in patients with limited small-cell lung carcinoma (SCLC) treated by four consecutive alternating protocols, using a competing risk approach with local recurrences, distant metastases, and death unrelated to cancer as competing events.

PATIENTS AND METHODS

Two hundred two patients with limited SCLC were included in four consecutive protocols alternating radiotherapy and chemotherapy (CT). The alternating schedule consisted of six cycles of CT (doxorubicin, etoposide [VP16213], and cyclophosphamide [CAVP16], plus methotrexate in the first protocol; cisplatin replaced methotrexate in the other three protocols) and three courses of thoracic radiotherapy at a total dose of 45, 55, 65, and 61 Gy in the four consecutive protocols, respectively (accelerated hyperfractionation was used in the first course of the fourth protocol). A 1-week rest followed each CT cycle and each course of radiotherapy. Seventy-six percent of patients were in complete remission at the end of the induction treatment. RFS variables were determined according to a model assuming competing risks to define the first cause of failure (local disease, distant metastasis, or intercurrent death).

RESULTS

No significant differences were observed between the four treatment groups. Overall results showed a 2-year cumulative incidence rate of failure of 75%. When analyzed, the first cause of failure was local recurrence only, 33%; distant only, 25%; distant and local simultaneously, 9%; and intercurrent death, 8%.

CONCLUSIONS

The methodology of competing risks allowed an unequivocal description of first events in limited SCLC. The extent of the local problem has been relatively overshadowed by the use of conventional descriptive methods.
Relationships between carboplatin exposure and tumor response and toxicity in patients with ovarian cancer.
Authors: Jodrell D I , Egorin M J , Canetta R M , Langenberg P , Goldbloom E P , Burroughs J N , Goodlow J L , Tan S , Wiltshaw E
Published: February 2017

PURPOSE

The study was undertaken to define the relationship between tumor response and carboplatin area under the curve (AUC) in patients with ovarian cancer; to study the relationship between carboplatin AUC and myelosuppression in the same population; to establish the true impact of carboplatin AUC, prior therapy, and pretreatment platelet and WBC counts on toxicity; and to define an optimal carboplatin exposure for treating patients with ovarian cancer.

METHODS

With the equation AUC = dose/(glomerular filtration rate [GFR]+25), carboplatin AUC (course 1) was calculated for 1,028 patients (450 previously untreated) who received single-agent carboplatin (40 to 1,000 mg/m2) for advanced ovarian cancer. GFR was measured (chromium-51-edathamil [51Cr-EDTA] or creatinine clearance) in all patients.

RESULTS

Regression analysis showed that carboplatin AUC, prior treatment, and Eastern Cooperative Oncology Group grade performance status (PS) are predictors of tumor response, thrombocytopenia, and leukopenia. Pretreatment platelet and WBC counts are additional predictors of thrombocytopenia and leukopenia, respectively. Although the likelihood of tumor response increased with increasing carboplatin AUC, this relationship was nonlinear. In all patient subsets, the likelihood of complete response (CR) or overall response did not increase significantly above a carboplatin AUC of 5 to 7 mg/mL x minutes. At any given carboplatin AUC, thrombocytopenia occurred more frequently than leukopenia, although both approached 100% as carboplatin AUC increased. Both thrombocytopenia and leukopenia were more frequent in pretreated than in untreated patients regardless of pretreatment count. At any carboplatin AUC, the influence of PS on likelihood of response and toxicity was profound.

CONCLUSION

Carboplatin dosing by AUC will lead to more predictable toxicity, and increasing carboplatin AUC above 5 to 7 mg/mL x minutes does not improve the likelihood of response but does increase myelotoxicity. Therefore, careful evaluation of high-dose carboplatin therapy in a prospective, randomized trial is needed before such treatment becomes accepted practice.
Significance of epidermal growth factor receptor in advanced ovarian cancer.
Authors: Scambia G , Benedetti Panici P , Battaglia F , Ferrandina G , Baiocchi G , Greggi S , De Vincenzo R , Mancuso S
Published: February 2017

PURPOSE

The purpose of this study was to investigate the significance of epidermal growth factor receptor (EGF-R) expression in a group of advanced ovarian carcinomas.

PATIENTS AND METHODS

The study was conducted on 72 previously untreated patients with International Federation of Gynecology and Obstetrics (FIGO) stage III-IV disease. The median follow-up was 24 months (range, 4 to 75 months). EGF-R was measured by a radioreceptorial assay. A cutoff of 1.5 fmol per milligram of protein was chosen to define EGF-R positivity. Medians and life tables obtained with the Kaplan and Meier method were analyzed by the log-rank test. The risk of progression was estimated by Cox's proportional hazards model.

RESULTS

EGF-R was detected in 54% of primary tumors. When EGF-R was analyzed in different tissue specimens of the same tumor, consistent findings were noted in 88% (seven of eight) of cases. A lower concordance rate (nine of 15; 60%) was found between primary tumors and omental metastases, with a tendency toward higher EGF-R levels in the latter. The EGF-R expression did not significantly correlate with age, stage, grading, and residual tumor after primary surgery. In the univariate analysis, stage IV disease, postoperative residual tumor diameter greater than 2 cm, presence of ascites, and EGF-R positivity were found to be significantly associated with a greater risk of disease progression. In the multivariate analysis, only the postoperative residual tumor and the EGF-R expression remained significantly associated with a high risk of progression.

CONCLUSION

Data reported here suggest that the presence of EGF-R in advanced ovarian tumor at the time of the primary surgery identifies a subset of patients with a particularly poor prognosis.
Surveillance after orchidectomy for patients with clinical stage I nonseminomatous testis tumors.
Authors: Sturgeon J F , Jewett M A , Alison R E , Gospodarowicz M K , Blend R , Herman S , Richmond H , Thomas G , Duncan W , Munro A
Published: February 2017

PURPOSE

This study was designed to determine the proportion of patients with clinical stage I nonseminomatous germ cell tumors of the testis (NSGCTT) managed with surveillance after orchidectomy who have more advanced disease and, therefore, require further treatment, the time to progression, the sites of progression, and the efficacy of treatment delayed until progression was recognized.

PATIENTS AND METHODS

One hundred five patients were observed prospectively without further treatment after orchidectomy and full clinical staging. Treatment was given immediately upon detection of marker-positive, clinical, or radiologic evidence of disease.

RESULTS

Thirty-seven patients (35.2%) have required further therapy for disease progression, occurring from 2 to 21 months after diagnosis. Thirty-six patients have been successfully treated. Overall, 104 patients (99%) remain alive and free of disease at 12 to 121 months after orchidectomy. Progression occurred in the retroperitoneum in 25 of 37 patients who developed further disease on surveillance. The presence of vascular invasion in the primary tumor was predictive of an increased risk of progression.

CONCLUSION

Surveillance is a valid alternative to immediate retroperitoneal lymph node dissection in patients with clinical stage I NSGCTT but should be recommended only under the close supervision of physicians experienced in the diagnosis and treatment of testicular cancer.
Treatment of recurrent gliomas and metastatic brain tumors with a polydrug protocol designed to combat nitrosourea resistance.
Authors: Levin V A , Prados M D
Published: February 2017

PURPOSE

The study was undertaken to evaluate a chemotherapy protocol against recurrent malignant gliomas that was designed to combat presumed chloroethyl-nitrosourea (NU) resistance.

PATIENTS AND METHODS

All patients had malignant gliomas and had failed prior therapy. Patients were stratified as having either glioblastoma multiforme (GM) or anaplastic gliomas (AG) and as having failed radiotherapy (RT) only or both RT and chemotherapy. Chemotherapy consisted of six drugs: before lomustine (CCNU), thioguanine (TG), dibromodulcitol (mitolactol; DBD), and procarbazine (PCB) were given to enhance CCNU-induced tumor-cell kill and to reduce alkyltransferase repair of ethylated DNA. A fluorouracil-hydroxyurea (FUHU) combination was given 2 weeks later to kill cells that began to cycle after the challenge of the first four drugs (TPDC-FUHU chemotherapy).

RESULTS

Of the 88 assessable patients, 37 had GM, 38 had AG, and 13 had other primary and metastatic brain tumors. For GM patients, 61% had a partial response (PR) or stable disease (SD) for a median of 9.3 months if RT only failed, and 58% had a PR or SD for a median of 5.1 months if they had previously been treated with an NU. For AG patients, 92% had a PR or SD for a median of 15 months if RT only had failed, but only 38% had a PR or SD for a median of 10.6 months if they had been previously treated with a NU. Activity was also seen against other recurrent or progressive primary and metastatic brain tumors.

CONCLUSIONS

TDPC-FUHU chemotherapy is a highly effective form of chemotherapy for both recurrent GM and AG patients. This study suggests but does not prove that this combination may be superior to other NU-based treatments for recurrent malignant glioma patients who fail RT. Because of the activity of this chemotherapy, we intend to evaluate more fully this approach in a randomized study.
Inflammatory breast cancer: a review.
Authors: Jaiyesimi I A , Buzdar A U , Hortobagyi G
Published: February 2017

PURPOSE

The natural history of inflammatory breast cancer and the recent advances in its management were reviewed.

DESIGN

The English medical literature from 1924 to 1990 was reviewed using the Cancerline and Medline retrieval systems, and through a manual review of bibliographies of identified articles.

RESULTS

The majority of patients with inflammatory breast cancer treated only with local therapies died 18 to 24 months after diagnosis. A combined modality approach with chemotherapy, surgery, and radiation therapy has improved disease-free and overall survival rates for inflammatory breast cancer. Approximately 35% to 55% of patients treated with combined modality regimens remain disease-free and alive at 5 years.

CONCLUSION

Induction combination chemotherapy administered with radiation therapy, mastectomy, both, or with additional chemotherapy favorably alters the natural history of inflammatory breast cancer. New drug combinations and high-dose chemotherapy with autologous bone marrow support are being evaluated to improve further patient survival.
Cisplatin-based combination chemotherapy in the treatment of poorly differentiated carcinoma and poorly differentiated adenocarcinoma of unknown primary site: results of a 12-year experience.
Authors: Hainsworth J D , Johnson D H , Greco F A
Published: February 2017

PURPOSE

We previously reported excellent responses to cisplatin-based chemotherapy in a minority of patients with poorly differentiated carcinoma (PDC) or poorly differentiated adenocarcinoma (PDA) of unknown primary site. We have continued to study and to treat these patients, and now report clinical characteristics, treatment results, and prognostic factors in a large group of patients identified prospectively.

PATIENTS AND METHODS

Between February 1978 and December 1989, we treated 220 patients with PDC or PDA of unknown primary site. The median age was 39 years; 48% of patients had predominant tumor location in the mediastinum, retroperitoneum, or peripheral lymph nodes. Specialized pathologic studies resulted in the identification of specific tumor types in only a few cases. All patients received cisplatin-based chemotherapy; between 1978 and 1984, 116 patients received cisplatin, vinblastine, and bleomycin (PVeB) +/- doxorubicin, and 104 patients treated since January 1985 received cisplatin and etoposide +/- bleomycin.

RESULTS

One hundred thirty-eight patients (63%) had objective responses to therapy, and 58 (26%) had complete response. Thirty-six patients (16%) are currently disease-free at a median of 61 months following therapy (range, 11 to 142 months). Actuarial 10-year survival is 16%. Favorable prognostic factors identified by Cox regression analysis include: (1) predominant tumor location in the retroperitoneum or peripheral lymph nodes, (2) tumor limited to one or two metastatic sites, (3) no history of cigarette use, and (4) younger age.

CONCLUSION

Patients with PDC or PDA of unknown primary site represent another group of patients for whom potentially curative therapy is available. Patients with this syndrome should be distinguished from patients with well-differentiated adenocarcinoma of unknown primary site, and should receive a trial of cisplatin-based chemotherapy.
Identification of estrogenic tamoxifen metabolite(s) in tamoxifen-resistant human breast tumors.
Authors: Wiebe V J , Osborne C K , McGuire W L , DeGregorio M W
Published: February 2017

PURPOSE

We have shown previously that acquired tamoxifen resistance in an in vivo experimental model is associated with reduced tamoxifen accumulation, isomerization of trans-4-hydroxytamoxifen, and tamoxifen-stimulated tumor growth. The purpose of this study is to isolate and verify the presence of estrogenic tamoxifen metabolites in human breast tumors using high-performance liquid chromatography (HPLC) and mass-spectrometry (MS) techniques.

PATIENTS AND METHODS

In the present study, we used HPLC and MS to identify the presence of estrogenic metabolites in tumor samples excised from athymic nude mice and in human breast tumors isolated from patients receiving adjuvant tamoxifen therapy.

RESULTS

We identified the presence of metabolite E, a known estrogenic metabolite of tamoxifen, in tamoxifen-resistant MCF-7 human breast tumors implanted in athymic nude mice, as well as in tumors from patients with clinical resistance. Additionally, we separated another estrogenic metabolite, bisphenol, by HPLC, and this was also tentatively confirmed by MS analysis.

CONCLUSION

These data suggest that cellular tamoxifen metabolism to estrogenic metabolites may in part contribute to stimulating the growth of hormone-responsive breast tumors following prolonged exposure to tamoxifen. Further evaluation of the relationship between cellular metabolism and acquired tamoxifen resistance is warranted.
A randomized comparison of cisplatin alone or in combination with methotrexate, vinblastine, and doxorubicin in patients with metastatic urothelial carcinoma: a cooperative group study.
Authors: Loehrer P J , Einhorn L H , Elson P J , Crawford E D , Kuebler P , Tannock I , Raghavan D , Stuart-Harris R , Sarosdy M F , Lowe B A
Published: February 2017

PURPOSE

A prospective randomized trial was performed to determine if the addition of methotrexate, vinblastine, and doxorubicin to cisplatin (M-VAC) imparted a response rate or a survival advantage over single-agent cisplatin in patients with advanced urothelial carcinoma.

PATIENTS AND METHODS

From October 1984 through May 1989, 269 patients with advanced urothelial carcinoma were entered onto this international intergroup trial and randomized to receive intravenous (IV) cisplatin (70 mg/m2) alone or with methotrexate (30 mg/m2 on days 1, 15, 22), vinblastine (3 mg/m2 on days 2, 15, 22) plus doxorubicin (30 mg/m2 on day 2). Cycles were repeated every 28 days until tumor progression or a maximum of six cycles. There were 246 fully assessable patients of whom 126 were randomized to cisplatin alone and 120 were randomized to the M-VAC regimen.

RESULTS

As expected, the M-VAC regimen was associated with a greater toxicity, especially leukopenia, mucositis, granulocytopenic fever, and drug-related mortality. Response rates were superior for the M-VAC regimen compared with single-agent cisplatin (39% v 12%; P less than .0001). Similarly, the progression-free survival (10.0 v 4.3 months) and overall survival (12.5 v 8.2 months) were significantly greater for the combined therapy arm.

CONCLUSION

Although a more toxic regimen, we found M-VAC to be superior to single-agent cisplatin with respect to response rate, duration of remission, and overall survival in patients with advanced urothelial carcinoma.
Prognosis and treatment of lymphoblastic lymphoma in adults: a report on 80 patients.
Authors: Morel P , Lepage E , Brice P , Dupriez B , D'Agay M F , Fenaux P , Gosselin B , Bauters F , Gisselbrecht C
Published: February 2017

PURPOSE

We analyzed prognostic factors in 80 adult patients with lymphoblastic lymphoma (LBL).

PATIENTS AND METHODS

Twenty-one patients received six monthly courses of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) and maintenance chemotherapy for 12 months. The LNH-84 protocol (30 patients) consisted of four courses of high-dose CHOP followed by consolidation for 4 months. Both FRALLE (22 patients) and LALA (seven patients) protocols were two intensive chemotherapy regimens for acute lymphoblastic leukemia (ALL) that included an induction with daunorubicin, vincristine, cyclophosphamide, prednisolone (and asparaginase for the FRALLE regimen), consolidation, and maintenance chemotherapy that lasted for 2 years.

RESULTS

Sixty-six patients (82%) achieved a complete remission (CR). The CR duration rate and overall survival rate at 30 months were estimated to be 46% and 51%, respectively, with a median follow-up of 55 months. Only two of 37 relapses occurred after 26 months. Chemotherapy protocol did not influence CR rate, CR duration, and survival. A higher CR rate was associated with an age of less than 40 years, lactic dehydrogenase (LDH) level of less than two times the upper limits of normal, and no or one extranodal site of disease. Short survival was associated with a failure to achieve CR, age older than 40 years, B symptoms, LDH level more than two times the upper limits of normal, and hemoglobin level of less than 100 g/L. Bone marrow involvement had no prognostic value. We could not evaluate precisely the prognostic value of Ann Arbor stage because inclusion criteria differed among treatment groups.

CONCLUSION

Our findings suggest that age and LDH are two important pretreatment prognostic factors for adult LBL, and that the optimal prognostic staging system remains a controversial issue.
Hepatic arterial infusion of floxuridine in patients with liver metastases from colorectal carcinoma: long-term results of a prospective randomized trial.
Authors: Rougier P , Laplanche A , Huguier M , Hay J M , Ollivier J M , Escat J , Salmon R , Julien M , Roullet Audy J C , Gallot D
Published: February 2017

PURPOSE

A multicentric randomized study that compared patients who received intrahepatic arterial infusion (HAI) to a group of patients who did not receive HAI (control group) was performed for unresectable hepatic metastases from primary colorectal carcinoma.

PATIENTS AND METHODS

One hundred sixty-six patients were assigned randomly to HAI of floxuridine (5 fluoro-2'deoxyuridine [FUDR]) 0.3 mg/kg/d for 14 days every 4 weeks or to the control group; this latter group, depending on the investigator's choice, was either under observation or received systemic fluorouracil (5-FU). The same regimen of systemic 5-FU also was administered to the HAI group in the event of extrahepatic progression. No crossover from the control group to the HAI group was permitted. The mean duration of follow-up was 54 months (range, 31 to 72), and 163 patients were analyzed.

RESULTS

A significant improvement was observed in the survival rate for the 81 patients assigned to HAI group (P less than .02) with a 1-year survival rate of 64% versus 44% in the control group (82 patients). The 2-year survival rate was 23% versus 13%. The median survival was 15 months versus 11 months for the HAI group and the control group, respectively. Survival was better for patients with a less than 30% liver involvement, and for those treated in more specialized centers. The hepatotoxic effects of HAI were observed in 47 patients (chemical hepatitis [n = 28], and biliary sclerosis [n = 19]). The 1-year rate of sclerosing cholangitis was equal to 25%. Gastrointestinal toxicity was infrequent and consisted of gastritis or diarrhea.

CONCLUSIONS

Therapy with HAI of FUDR improves the survival of patients with liver metastases over colorectal carcinoma. However, the methods that are used to diminish the toxicity of HAI and efficient systemic chemotherapy, such as a combination of 5-FU and leucovorin, are required to prevent extrahepatic metastases.

PURPOSE

A single-institution phase II study was undertaken to evaluate the efficacy and toxicity of interleukin-2 (IL-2) administered by subcutaneous injection.

PATIENTS AND METHODS

Twenty-seven unselected patients (15 male) with a mean age of 60 years (range, 42 to 76 years) who had advanced renal cell cancer were treated as outpatients. IL-2 was given once a day, 5 days per week for 6 weeks. During the first 5-day cycle, 18 x 10(6) IU was given once daily; in the following cycles, the doses in the first 2 days were reduced to 9 x 10(6) IU. After a 3-week rest period, treatment was repeated in patients who had a response or stable disease (SD). To prevent pyretic reactions, patients also received acetaminophen (250 to 500 mg given orally every 4 to 6 hours).

RESULTS

After 6 weeks, 26 patients were assessable for response. Two patients (8%) had a complete remission (CR), four (15%) had a partial remission (PR), and 13 (50%) had SD. A second cycle of 6 weeks was given to 19 patients; one patient with a PR and six with SD showed progression. Duration of the CR was 17+ and 19+ months, and length of the PR was 2, 8, 11, and 11+ months. The median survival of the patients who were nonresponders and responders was 10 and 20+ months, respectively, and for all patients was 13 months. One patient died as a result of myocardial infarction and brain stem ischemia. Systemic side effects in the other patients were tolerated and accepted, and included transient inflammation and local induration at the injection sites, fever and chills, and nausea.

CONCLUSION

Subcutaneous IL-2 is clinically active, has an acceptable toxicity, and can be given to patients with concomitant disease.

PURPOSE

A phase I trial was undertaken because interleukin-1 alpha (IL-1 alpha) possesses antiproliferative, immunostimulatory, antiinfection, myeloprotective, and myelorestorative properties that could be beneficial in cancer treatment.

PATIENTS AND METHODS

In this phase I trial, IL-1 alpha was administered intravenously (IV) during a 15-minute period daily for 7 days to patients with advanced solid malignancies.

RESULTS

The maximum-tolerated dose (MTD) of IL-1 alpha alone was 0.3 microgram/kg. A second group of patients received indomethacin plus IL-1 alpha based on preclinical studies, which indicated that indomethacin could abrogate IL-1 alpha-induced hypotension; however, the MTD of IL-1 alpha plus indomethacin was 0.1 microgram/kg lower than IL-1 alpha alone. Fever, chills, headache, nausea, vomiting, and myalgia were common but were not dose-limiting. Hypotension resulted from a marked decrease in systemic vascular resistance and required pressors at 0.3 and 1.0 micrograms/kg IL-1 alpha. Dose-limiting toxicities included hypotension, myocardial infarction, confusion, severe abdominal pain, and renal insufficiency. IL-1 alpha treatment caused a significant, dose-related increase in the total WBC count (mainly segmented neutrophils and neutrophilic bands). Bone marrow cellularity increased because of enhanced numbers of relatively mature myeloid cells and megakaryocytes. Platelet counts decreased during therapy but were significantly elevated above baseline values 1 to 2 weeks posttreatment; this may have been an effect of IL-6 that was shown to be induced by IL-1 alpha treatment. Significant increases in triglycerides, cortisol, C-reactive protein, thyroid-stimulating hormone and decreases in cholesterol, testosterone, and protein-C were observed with treatment.

CONCLUSION

We conclude that at doses of IL-1 alpha that can be given safely to cancer patients, significant, potentially beneficial hematopoietic effects occur.

PURPOSE

To evaluate the response rate and the immunorestorative properties of subcutaneously administered interferon alfa-2b (IFN-A2b) in patients with advanced renal cell carcinoma (RCC) and to correlate the immune status with the clinical responses.

PATIENTS AND METHODS

Twenty-six patients with advanced RCC were treated with recombinant IFN-A2b. The dose was increased progressively from 5 x 10(6) IU the first week to 10 x 10(6) IU the second week, and thereafter to 15 x 10(6) IU subcutaneously.

RESULTS

Four patients (15%) achieved partial responses (PRs), and five patients (19%) had stable disease (S), whereas 17 patients (65%) progressed. In all patients, blood was withdrawn before IFN treatment and monthly thereafter. T lymphocytes after isolation from peripheral blood were tested for proliferation in the autologous mixed lymphocyte reaction (autoMLR) and allogeneic mixed lymphocyte reaction (alloMLR), interleukin-2 (IL-2) production, expression of IL-2 receptors during the alloMLR, and the production of interleukin-1 (IL-1) by peripheral-blood monocytes. Twelve patients were assessable, four patients had a PR, one patient had S, and seven patients had progressive disease. Striking increases were demonstrated in all parameters 1 month after treatment with IFN-A2b in the four patients who responded and the patient with S. Namely, the autoMLR responses showed a mean increase of 250%, the IL-2 production 247%, the expression of IL-2-specific receptors 446%, the alloMLR responses 160%, and the production of IL-1 262%. On the contrary, the nonresponders did not show any change in their overall immune status, and in some, deterioration of the already depressed immunologic functions was observed.

CONCLUSIONS

Administration of IFN-A2b results in a marked potentiation of deficient cellular immune response in vitro in those patients with RCC who respond to the treatment. This may have prognostic significance, and certainly more patients are required to be studied for definite conclusions.

Published: February 2017

PURPOSE

The purpose of this study was to optimize the dose, schedule, and timing of recombinant granulocyte-macrophage colony-stimulating factor (GM-CSF) administration that would best abrogate myelosuppression in patients with sarcoma.

PATIENTS AND METHODS

Sarcoma patients who had experienced severe myelosuppression after chemotherapy with Cytoxan (cyclophosphamide; Bristol-Myers Squibb Co, Evansville, IN), Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), and dacarbazine ([CyADIC], cycle 1) were eligible. GM-CSF was administered during a 14-day period until 1 week before cycle 2 of CyADIC and was resumed 2 days after cycle 2 completion. The schedule subsequently was modified to allow the earlier administration of GM-CSF in which CyADIC was compressed from 5 days to 3 days, and GM-CSF was administered immediately after the discontinuation of CyADIC in cycle 2. To understand better the impact of GM-CSF on bone marrow stem cells, the proliferative status of bone marrow progenitors was examined during treatment. To evaluate the effects of GM-CSF on effector cells, select functions of mature myeloid cells were also examined.

RESULTS

In the seven patients who were treated on the initial schedule, GM-CSF enhanced the rate of neutrophil recovery; however, severe neutropenia was not abrogated, By using the modified schedule in 17 patients, GM-CSF significantly reduced both the degree and the duration of neutropenia and myeloid (neutrophils, eosinophils, and monocytes) leukopenia. The mean neutrophil and mature myeloid nadir counts were 100/mm3 and 280/mm3 in cycle 1 and 290/mm3 and 1,540/mm3 in cycle 2 (P less than .01 and P less than .001). The duration of severe neutropenia (neutrophil count less than 500/mm3) and myeloid leukopenia (myeloid leukocyte count less than 1,000/mm3) were reduced from 6.2 and 6.8 days in cycle 1 to 2.8 and 1.4 days in cycle 2 (P less than .001). While 16 of 17 patients experienced severe myeloid leukopenia (less than 500/mm3) in cycle 1, only two of 17 experienced severe myeloid leukopenia in cycle 2 (P less than .001). Overall, severe neutropenia was abrogated in seven patients, which made them eligible for dose-escalation of Adriamycin. The fraction of cycling progenitors increased threefold on GM-CSF and decreased dramatically below the baseline within 1 day of GM-CSF discontinuation.

CONCLUSIONS

The modified schedule improved the beneficial effects of GM-CSF by enhancing myeloprotection and permitting dose-intensification of chemotherapy. The increased myeloid mass and quiescent progenitors at the initiation of chemotherapy suggest that GM-CSF might allow further chemotherapy dose-rate intensification by shortening the interval between courses.
Infants with neuroblastoma and regional lymph node metastases have a favorable outlook after limited postoperative chemotherapy: a Pediatric Oncology Group study.

Published: February 2017

PURPOSE

Infants less than or equal to 1 year of age with neuroblastoma (NB) have a favorable outlook with minimal to moderate therapy. Patients with complete or partial removal of the primary tumor but positive intracavitary lymph nodes (Pediatric Oncology Group [POG] stage C) have a higher risk for recurrent disease. To determine the importance of distinguishing infants with POG stage C NB from those with POG stage B disease and to assess the efficacy and toxicity of treating POG stage C infants with limited, postoperative chemotherapy, a study was conducted by the POG.

PATIENTS AND METHODS

Forty-four eligible POG stage C infants received cyclophosphamide 150 mg/m2 orally on days 1 to 7 and Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH) 35 mg/m2 intravenously (IV) on day 8 (CYC/ADR), every 3 weeks for five courses followed by second-look surgery. No continuation therapy was given if surgical and pathologic complete response (CR) was achieved. Secondary therapy with five courses of cisplatin 90 mg/m2 on day 1 followed by teniposide (VM-26) 100 mg/m2 on day 3 (CDP/VM) was given to infants with gross residual tumor after CYC/ADR and second-look surgery.

RESULTS

Thirty-four infants achieved CR after CYC/ADR alone, three after CYC/ADR and second-look surgery, two after CYC/ADR, surgery, and maintenance therapy, and two after alternative treatment with CDP/VM (total CR rate, 42 of 44). The 3-year survival and disease-free survival are both 93%. Toxicity was nominal.

CONCLUSIONS

Infants with POG stage C NB have a favorable outlook, which is similar to infants with POG stage B NB; the surgical staging procedure for distinguishing these infant subsets may not be necessary. Future studies should focus on the reduction of treatment toxicity and efficacy maintenance, and address methods to identify infants at risk for failure.
Radiosurgery as part of the initial management of patients with malignant gliomas.
Authors: Loeffler J S , Alexander E , Shea W M , Wen P Y , Fine H A , Kooy H M , Black P M
Published: February 2017

PURPOSE

Between May 1988 and May 1991, 41 patients with malignant gliomas were enrolled onto a prospective study designed to evaluate the role of radiosurgery as a component of initial management.

PATIENTS AND METHODS

Thirty-seven patients underwent radiosurgery according to the protocol and were assessable for survival and complications of treatment. Diagnoses included glioblastoma multiforme (GBM) in 23 (62%) cases and anaplastic astrocytoma in 14 (38%) cases. In 20 (54%) cases, surgical resection was attempted initially, whereas 17 (46%) patients underwent biopsy only. Patients in the study group received external-beam radiotherapy that consisted of 5,940 cGy given in 33 fractions to partial brain fields that encompassed the primary tumor with a 3 to 4 cm margin. Radiosurgery, used as a technique for boosting the dose to any residual contrast-enhancing mass lesion, was given 2 to 4 weeks after the completion of conventional radiotherapy. Minimum radiosurgical doses ranged from 1,000 to 2,000 cGy (median, 1,200 cGy), whereas maximum doses ranged from 1,250 to 2,500 cGy (median, 1,500 cGy). The median tumor volume at the time of radiosurgery was 4.8 cm3 (range, 1.2 to 72 cm3). Adjuvant chemotherapy was not given.

RESULTS

After a median follow-up of 19 months, only nine of 37 (24%) patients have died. Six patients (all glioblastoma multiforme) died of recurrent tumor, whereas death was attributable to complications of treatment in two cases and intercurrent disease in one case. Four patients with recurrent tumor failed at the margins of the radiosurgical treatment volume, whereas two patients progressed locally. One patient is alive with local and marginal failure. Seven (19%) patients underwent reoperation at a median time of 5 months (range, 1 to 14 months) after radiosurgery.

CONCLUSION

We conclude that radiosurgery is a useful adjunct to other modalities in the initial management of patients with small, radiographically well-defined malignant gliomas.
