Cisplatin and dacarbazine are used widely in the treatment of metastatic melanoma. To evaluate high-dose cisplatin and dacarbazine, 32 patients with metastatic melanoma were treated with cisplatin 50 mg/m2 and dacarbazine 350 mg/m2 daily for three days repeated at 28-day intervals. Their median age was 43.5 years (range, 25 to 73 years), and their median Karnofsky performance status was 80% (range, 70% to 100%). Measurable and evaluable disease sites (number of patients) included lymph nodes (22), lung (17), soft tissue (16), liver (13), bone (seven), spleen (four), adrenal gland (three), skin (three), and other sites (five). Patients received a median of two cycles of therapy (range, one to eight cycles). Thirty patients were evaluable for response. No complete responses were observed. Five patients had a partial response (17%; 95% confidence interval, 3% to 30%) for 16+, 12+, 7, 6.5, and 3 months. Responding sites of disease included lymph nodes (five of 22), lung (three of 17), and soft tissue (two of 16). Hematologic toxicity (Grade greater than or equal to 3) included neutropenia (16 of 32 patients, 30 of 90 cycles), thrombocytopenia (eight of 32 patients, 12 of 90 cycles), and anemia (five patients). Nine episodes of neutropenia and fever were seen in four patients; two had bacteremia. Nonhematologic toxicity (Grade greater than or equal to 3) included hypotension (two patients), nausea and vomiting (four), neuropathy (two), ototoxicity (four), and hypomagnesemia (nine). The low objective response rate and severe toxicity of this regimen preclude its standard use in patients with metastatic melanoma. A review of cisplatin-based therapy in metastatic melanoma suggests that there is no dose-response relationship. The use of high-dose cisplatin (greater than 100 mg/m2) in the treatment of metastatic melanoma is not recommended.

Fifteen patients with metastatic malignant melanoma, including 10 who had not previously received systemic therapy, were treated with recombinant alpha2-interferon (IFN-alpha 2) in a dose of 20 million IU/m2 by 30-min i.v. infusion daily for 5 days each 14 days. Evaluable metastatic sites included lung, subcutaneous tissue, liver, nodes, adrenals, and bone. Subjective toxicity was generally mild to moderate, with fever (38.2-40.2 degrees C), occasional rigors, fatigue, myalgia, headache, and nausea. Objective toxicity included transient neutropenia and elevation of hepatic enzymes, particularly gamma-glutamyl transpeptidase. In 1 of the 10 patients receiving more than one cycle, IFN dosage was reduced because of toxicity, but later reescalated. All patients were evaluated for response. No overall partial or complete responses were observed, but two site responses (lung and subcutaneous tissue) were seen. Median survival from start of IFN treatment was 19 weeks. High doses of IFN were reasonably well tolerated in this study, but the results suggest little activity against malignant melanoma.

Four children with yolk sac tumor were treated with an aggressive combination chemotherapy program. Three children had presacral primary tumors, one having pulmonary metastases, and one had a testicular primary tumor with pulmonary metastases. Three children were treated when they had measurable disease, and one had no measurable disease. The chemotherapy program consisted of a 6-wk induction period with vincristine (VCR), cis-diamminedichloroplatinum (DDP), and bleomycin. Maintenance therapy consisted of VCR, actinomycin D, and cyclophosphamide (cytoxan) every 3-4 wk as tolerated. Treatment was discontinued after 12 mo of complete remission. All three patients with evaluable disease had a partial response (PR) to induction therapy. Two underwent surgical exploration following induction therapy, one a laparotomy and the other a thoracotomy, and were found to have only scar tissue at the sites of presumed residual disease. The third child with measurable disease progressed to a clinical complete response (CR) during maintenance therapy. Two patients have had no evidence of disease (NED) for 42+ and 41+ mo since starting therapy (28+ and 27+ mo since completing treatment). Two patients are NED 11+ and 7+ mo since starting therapy and remain on treatment. We have encountered no significant renal or pulmonary toxicity, and there have been only two hospitalizations during maintenance therapy for fever and neutropenia. These preliminary results employing different induction and maintenance chemotherapy programs and planned second-look surgical intervention appear encouraging.

The purpose of our study was to investigate the efficacy and toxicity of paclitaxel in patients with relapsed or refractory epithelial ovarian cancer in the context of a large multicentre study performed in the UK and Eire. Patients with previously treated epithelial carcinoma of the ovary or fallopian tube who fulfilled the eligibility criteria were entered in the study. Eligibility criteria included: measurable or evaluable disease; Eastern Cooperative Oncology Group (ECOG) performance status 0-2; up to three prior chemotherapy regimens, one of which had to contain a platinum agent; adequate haematological, renal and hepatic function; and no significant cardiac history. Patients received either 175 mg m-2 or 135 mg m-2 paclitaxel. The lower dose was administered to patients who had received more than two prior chemotherapy regimens. Paclitaxel was given by i.v. infusion over 3 h every 21 days. Response was assessed at three-cycle intervals or earlier if required. A total of 155 patients were registered for the study in the UK of whom 140 were eligible for response and toxicity evaluation, and 12 patients were assessed for toxicity only. Hair loss was the most frequently reported toxicity, with 74% (119/152) of patients reporting grade 3 alopecia. The most frequently reported serious toxicity was neutropenia, with 49% (74/152) of patients experiencing neutropenia grade 3 or 4. The response rate was 16% [two complete responders (CR), 20 partial responders (PR)], the median duration of response was 275 days and median survival was 244 days. Paclitaxel is active in relapsed and platinum-resistant epithelial ovarian cancer. It is well tolerated and can be given in an out-patient setting. The UK and Eire experience is very similar to that of US investigators in this group of patients. Further work is required to assess the optimal use of the drug in both first- and second-line therapy.

The objective of this phase II, multicenter, prospective study was to evaluate the safety and the response rate of paclitaxel administered to patients with ovarian cancer. Eligible patients had histologically proven ovarian carcinoma and measurable or evaluable disease and had received at least one platinum-containing regimen and no more than three prior chemotherapy regimens. Paclitaxel was given as a continuous intravenous (i.v.) infusion over 3 hours every 3 weeks. Dose was determined by the number of prior chemotherapy regimens. Patients with one or two prior chemotherapy regimens received 175 mg/m2 (group A) and patients with three prior chemotherapy regimens 135 mg/m2 paclitaxel (group B) after premedication. Treatment was repeated every 3 weeks. An interim safety analysis for the first 99 evaluable patients, 72 treated with 175 mg/m2 and 27 treated with 135 mg/m2 paclitaxel, is reported here. Median number of courses analyzed per patient was four (range, 1 to 6) in the two groups, for a total of 393 courses evaluable for toxicity (286 in group A, 107 in group B). World Health Organization (WHO) grade 3-4 neutropenia was observed in 29.6% of courses in group A and in 23.3% in group B. Two group A patients, 1 at courses 3 and 4 and 1 at course 6, experienced WHO grade 2 fever or infection associated with a WHO grade 4 neutropenia.(ABSTRACT TRUNCATED AT 250 WORDS)

TAXOL (paclitaxel), a new cytotoxic agent of the taxane class, has demonstrated activity against ovarian cancer. To address questions of a dose-response effect and the value of premedication to prevent hypersensitivity reactions during brief TAXOL infusions, a trial with a 2 x 2 factorial design was begun in patients with relapsed ovarian cancer. From July 1991 through March 1992, 407 patients who had failed one or two prior platinum regimens and who had measurable or evaluable disease were randomized to either 175 or 135 mg/m2 TAXOL administered by either 24- or 3-h infusion. Premedication to prevent hypersensitivity reactions, consisting of steroids, antihistamines, and H2-blockers, was administered to all patients before TAXOL. Toxicity and response data on 298 and 286 patients, respectively, are presented. Overall response rate was 18.5% (53 of 286 patients, 95% confidence interval 13.9% to 23.2%). The results suggest that TAXOL can be given safely over 3 h with premedication. Neutropenia appears to be related more to schedule than to dose, although neuropathy is primarily dose-related. Responses occurred more frequently in those who received 175 mg/m2, but analysis of all accrued patients is necessary before a final conclusion can be drawn. Studies administering TAXOL over 3 h at maximally tolerated doses are warranted.

Vinorelbine (Navelbine; Burroughs Wellcome Co, Research Triangle Park, NC; Pierre Fabre Medicament, Paris, France), a semisynthetic vinca alkaloid, and ifosfamide have each shown activity as a single agent and in various combination-chemotherapy regimens against non-small cell lung cancer. Vinorelbine usually has been given on a once-weekly schedule. We designed a phase I study adding escalating doses of vinorelbine on a novel schedule of 3 consecutive days to ifosfamide in a dose-intensive regimen with granulocyte colony-stimulating factor. The goals were to define the dose-limiting toxicity and maximum tolerated dose of vinorelbine and to document the toxicity profile and the overall response and survival rates observed. Eligibility criteria included histologically or cytologically documented stage IIIB or stage IV non-small cell lung cancer, measurable or evaluable disease, and no prior chemotherapy. Treatment consisted of escalating doses of vinorelbine (starting at 15 mg/m2) on days 1, 2, and 3 and ifosfamide at 2 g/m2 and decreased to 1.6 g/m2 on days 1, 2, and 3. Granulocyte colony-stimulating factor was administered subcutaneously at 5 micrograms/kg on days 5 through 11 in all patients. Cycles were repeated every 21 days. Forty-two patients were treated. The median age was 58 years (age range, 34 to 75 years); 41 patients had a performance status of 0 or 1. Dose-limiting neutropenia was observed in two of three patients at the initial dose level of ifosfamide 2 g/m2 and vinorelbine 15 mg/m2. Ifosfamide was therefore decreased to 1.6 g/m2, and vinorelbine was subsequently escalated, with a maximum administered dose of 35 mg/m2. The recommended phase II dose was ifosfamide 1.6 g/m2 on days 1, 2, and 3 with vinorelbine 30 mg/m2 on days 1, 2, and 3, given with granulocyte colony-stimulating factor support, on a 21-day cycle. At the recommended phase II dose myelosuppression remained the most common toxic effect, with grade 3 or 4 neutropenia of brief duration occurring in 20 patients. Final analysis has not yet been completed, but responses have been observed at several dose levels. The maximum tolerated dose of vinorelbine given on days 1, 2, and 3 is 30 mg/m2 when given with ifosfamide at 1.6 g/m2 on days 1, 2, and 3 and granulocyte colony-stimulating factor support. Myelosuppression is the dose-limiting toxic effect. Future analyses of the data will report the overall response and survival rates in these patients.

The aim of this phase II study was to determine the efficacy of high-dose ifosfamide with moderate dose etoposide in childhood osteosarcoma. From January 1992 to January 1995, 27 children (15 male, 12 female) with relapsed or refractory evaluable osteosarcoma were included in a phase II study of two courses of ifosfamide 3g/m2/day and etoposide 75 mg/m2/day for 4 days. Median age was 14 years (7-19 years). All but one had received high-dose methotrexate and doxorubicin as first-line treatment. 22 patients had previously received ifosfamide. This regimen was given as first-line in 1 patient, second-line in 23 and third-line in 3. Evaluable disease was lung metastases in 21 patients, local relapse in 5 and adenopathy in 1. There were six complete responses, seven partial responses, three minor responses, six stable disease and five progressive disease (including one mixed response). Response rate was 48% (95% confidence interval, 29-67%). Duration of response was not available (10 responding patients had other treatments). Response rate was equivalent in the subgroup of 22 patients who had previously received ifosfamide (4 CR, 6 PR). Among 3 patients who received the phase II regimen as third-line chemotherapy, there was 1 PR. All but 4 patients had a well tolerated grade 4 neutropenia. Transient mild confusion or seizures were each observed once. 5 patients are alive 15-31 months after the beginning of chemotherapy. This combination of drugs at this dosage has tolerable toxicity, is efficient and deserves evaluation in phase III studies.

This study involved 25 elderly (> 65 years old) patients (pts) with unresectable non small cell lung cancer (NSCLC) who were not eligible for polychemotherapy. The diagnosis of NSCLC was histologically or cytologically documented, and all of them had measurable or evaluable disease. The median age of the patients was 71 (range 65-77); 9 had been pretreated. The pts received 25 mg/m2 of vinorelbine weekly or bi-weekly depending on the results of blood tests. The treatment continued until disease progression or tolerance. No complete response was achieved: 3 pts (12%) had a partial response (RP) (8-12-14 months), 13 (52%) stable disease (SD) with an improvement in symptoms, such as cough and/or pain, and 9 pts (36%) progressed. Compliance with the therapy was acceptable. The main toxicity was hematological: neutropenia was observed in 16 pts, with only 1 case of grade 4 neutropenia without sepsis; grade 1-2 anemia occurred in 8 patients. The other toxicities included grade 1-2 neurotoxicity in 8 pts, chemical phlebitis in 2 pts and grade 3 cardiotoxicity reversible with medical treatment in 1 patient. The median survival time was 10 months (lower quartile 5 months, upper quartile 23 months) (Kaplan and Meyer method). Vinorelbine can be considered a rational choice in elderly pts with advanced NSCLC who are not suitable for aggressive polychemotherapy, with the aim of improving their quality of life in terms of symptoms and outpatient treatment.

The aim of this study was to evaluate the toxicity and the activity of two non-cross-resistant platinum compounds: oxaliplatin (L-OHP) and cisplatin (CDDP) in platinum pretreated ovarian cancer patients. Chemotherapy consisted of L-OHP and CDDP given sequentially as 2 h infusions on day 1 at their standard recommended dose (130 mg/m2 for oxaliplatin, 100 mg/m2 for cisplatin) every 3 weeks. Dose reductions (20-35%) were planned according to baseline haematological and renal status, but the dose ratio between L-OHP and CDDP was always maintained at 1.3. Cycles were repeated until progression or treatment limiting toxicities. From September 1992 to November 1994, 25 patients with pretreated ovarian cancer entered this salvage programme. They had received a median number of three previous chemotherapy lines (1-7), one at least platinum based. Previously cisplatin had been given to 22 patients at a median total dose of 600 mg/m2 (170-1175), while 18 had received carboplatin to a median total dose of 1135 mg/m2 (200-2450). 9 patients had also received and were resistant to taxanes (paclitaxel, 6 patients, docetaxel, 3 patients), while the rest were considered ineligible for simultaneously ongoing single-agent taxane phase II trials. 13 and 12 patients, respectively, were considered to have platinum refractory and potentially sensitive disease, according to Markman's criteria. 77 cycles of L-OHP/CDDP were given, with a median of three cycles/patient (range 1-6) and were evaluable for toxicity. The limiting toxicity of the L-OHP/CDDP combination was a cumulative, sensory peripheral neuropathy, severe (> or = grade 3 CTC) after more than three cycles, but reversible within a few months of its discontinuation. Grade 3-4 (WHO scale) neutropenia and thrombopenia were seen in 35-40% of cycles, with one neutropenic treatment-related death (septic shock). 22 patients with measurable/evaluable disease were assessable for antitumoral activity. Two complete responses (CR) (8%) (one proven histologically at laparotomy (pCR)) and 8 partial responses (PR) (32%) for an overall objective response rate (ORR) of 40% (95% CI, 21-61%) (intent to treat). The median duration of response was 4 months. Seven responses were seen among 12 potentially platinum-sensitive tumours (58%, CI 95% 28-85%), while 3/13 platinum refractory patients (23%, CI 95% 5-54%) had an objective response. These encouraging results are the basis for new first- and second-line combination treatment programmes in ovarian carcinoma.
