Following extensive phase II trials of the combination of dacarbazine and interferon-alpha 2a we performed a prospective, randomized, controlled trial of this combination versus dacarbazine alone as systemic therapy for symptomatic, measurable metastatic malignant melanoma. The two treatment arms were well matched for age, sex, performance, status, relapse-free survival, prior therapy and sites of disease. Therapy consisted of dacarbazine given in combination in escalating doses of 200 mg/m2, 400 mg/m2 and 800 mg/m2 i.v. every 3 weeks, or alone at 800 mg/m2 i.v. every 3 weeks. Interferon was administered subcutaneously starting at 3 mU daily on days 1-3, 9 mU daily on days 4-70, then 9 mU three times per week. Therapy was continued for at least 6 months unless overt progressive disease was observed. Eighty seven patients were randomized to the combination and 83 patients to dacarbazine alone. Response rates were respectively, complete 7% and 2%, and partial 14% and 15%, for a total response rate of 21% (95% confidence limits 13-31%) and 17% (95% confidence limits 10-27%). Median duration of response was 258 and 286 days, and survival of the whole groups 229 and 269 days respectively. Toxicity was worse in the combination arm, with more patients experiencing fatigue, nausea and anorexia, flu-like symptoms and neutropenia. However quality of life was not significantly different in either group, except that fatigue, as measured at week 12 by LASA scales, and activity, as measured by the functional living index, were both improved in the combination.(ABSTRACT TRUNCATED AT 250 WORDS)

Melanoma is rare in Singapore with an age-standardised rate (ASR) of 0.4-0.8 per 100,000 per year. Thirteen patients with metastatic or locally advanced melanoma were referred to the Department of Medical Oncology, Singapore General Hospital between Feb 1991 and Nov 1993. Ten patients were given combination chemotherapy comprising carmustine (BCNU), cisplatin, dacarbazine (DTIC) and tamoxifen. The remaining 3 patients either rejected chemotherapy or were too ill to receive chemotherapy. Patient characteristics were as follows: there were 6 males and 4 females; age range 29-75 years; all were Chinese; sites of primary disease: extremities 8, retroorbital 1, vagina 1; sites of metastases: lymph nodes 6, skin 2, pulmonary 3, liver 1. All received the same combination chemotherapy comprising iv BCNU 150 mg/m2 q8wk, iv DTIC 220 mg/m2 x 3 days q4 wk, iv cisplatin 25 mg/m2 x 3 days q4 wk and tab tamoxifen 40 mg daily. There were 6 partial responses and no complete responses, giving a response rate of 60% with a median survival of 11.5 months. Three patients with sites of disease in the vagina, retroorbital region and metastatic liver disease had progressive disease despite chemotherapy and one died of treatment related sepsis. The 6 responders include those with metastases to the skin, nodes and/or lung. Treatment was generally tolerable. Two patients experienced delays of their subsequent cycles of treatment by 1-2 weeks due either to neutropenia and/or thrombocytopenia. This regimen is a fairly active combination against metastatic melanoma, particularly those with metastases to the nodes, skin and the lung. Those with involvement of other sites tend to respond poorly.

From May 1991 to January 1996, 54 patients with advanced malignant melanoma were enrolled into a phase II trial testing the new nitrosourea cystemustine, administrated intravenously as a 15 min infusion every 2 weeks at 90 mg/m2 for three cycles followed by 60 mg/m2. Out of the 54 enrolled patients, 10 were Ineligible, leaving 44 fully evaluable patients (World Health Organization criteria). Twenty one patients had already received first-line palliative chemotherapy and/or immunotherapy. The median age was 62 years (range 30-74 years) and the median performance status was 0 (grade 0, 19 patients; grade 1, 21 patients; grade 2, 4 patients). Five patients with partial responses (lasting 16-29 weeks, mean duration 24 weeks), nine with stable disease and 28 showing progression were observed, giving an overall response rate of 11% (confidence interval 3.8-24.6%). Toxicity was mild and consisted mainly of neutropenia (39% grade III-IV), thrombocytopenia (42% grade III-IV); febrile aplasia was rare. Cystemustine administered to this schedule appears to have limited clinical activity and acceptable toxicity in untreated or second-line advanced malignant melanoma.

The use of interleukin-2 (IL-2) and interferon-alpha (IFNalpha) in combination with chemotherapy for the treatment of advanced malignant melanoma has generated considerable interest. In particular, the relatively high number of durable complete responses has suggested this may be a significant advance in the treatment of malignant melanoma. We report our experience at the University of Colorado in 43 patients, including many with poor prognostic factors. Patients received cisplatin 20 mg/m2 on days 1-4, vinblastine 1.6 mg/m2 on days 1-4, dacarbazine 800 mg/m2 on day 1, IL-2 9 x 10(6) IU/m2 per day intravenously over 24h on days 1-4 and IFNalpha 5 x 10(6) IU/m2 per day subcutaneously on days 1-5 every 3 weeks. The median follow-up for all patients was 34 months. Responses were seen in 20 patients (47%, 95% confidence interval 31-62%) and comprised five complete responses (CRs) (12%) and 15 partial responses (PRs) (35%). Two patients achieving a CR remain disease free at 45 and 47 months follow-up. In addition three patients who obtained a surgical CR and another with only minor residual changes on computed tomography scan have not progressed at 27, 30, 40 and 27 months, respectively. Toxicity was manageable, but all patients had at least one grade 3 or 4 toxicity, predominantly hypotension and neutropenia. There were no treatment-related deaths. In conclusion, the response rate and duration is within the range previously reported for biochemotherapy. The results of ongoing randomized studies are awaited to better define the value of biochemotherapy in the treatment of advanced melanoma.

In this phase II study we assessed the efficacy of bryostatin-1 (NSC 339555) in metastatic melanoma patients when given intravenously either once a week at a dose of 25 microg/m2 per day over 24 h for 3 weeks or at 40 microg/m2 per day over 72 h every 2 weeks. Treatment courses were repeated every 4 weeks. Patients who had received one prior chemotherapy regimen for advanced melanoma, with or without biotherapy, were randomized to one or the other bryostatin-1 dose schedules until 12 patients were registered to each arm. Because there was one confirmed response among the 12 patients who received the 72 h dose schedule, 25 more patients were added to that arm. No prophylactic medications were given. Objective tumour measurements were used to assess the efficacy of the regimen. The National Cancer Institutes common toxicity criteria were used to grade reactions. In total, 49 patients with metastatic melanoma, none having symptomatic brain metastasis, were studied. Of these, 12 patients received the 24 h bryostatin-1 regimen, while the remaining 37 received the 72 h regimen. One patient receiving the 72 h regimen had a partial response lasting over 7 months. Muscle pain occurred in over 90% of the patients and was the dose-limiting side effect of the 72 h regimen. Grade 3/4 nausea and vomiting were more common on the 24 h regimen than on the 72 h one (35% versus 5% of patients). There was no therapy-related thrombocytopenia. Neutropenia was mild and mainly limited to patients receiving the 72 h regimen. Bryostatin-1 has limited activity against melanoma when given by 72 h intravenous infusion.

This randomized phase II trial was performed to define the activity and toxicity of the combination of dacarbazine (DTIC), carmustine (BCNU), cisplatin (DDP) and tamoxifen (DBDT regimen) versus DTIC alone in patients with metastatic melanoma. Sixty patients with metastatic melanoma were randomly assigned to receive BCNU 150 mg/m2 intravenously (i.v.) on day 1, cisplatin 25 mg/m2 i.v. daily on days 1 to 3, DTIC 220 mg/m2 i.v. daily on days 1 to 3 and tamoxifen 160 mg orally daily for 7 days prior to chemotherapy (DBDT arm; arm A). Treatment cycles were repeated every 28 days, while BCNU was given every two cycles. The DTIC arm (arm B) patients received DTIC alone 1200 mg/m2 i.v. on day 1, repeated every 21 days. Patients were evaluated every two cycles; responding patients continued the treatment for a maximum of 12 cycles. The overall response rate was 26% in the DBDT arm and 5% in the DTIC arm. Complete responses were 2.5% for DBDT and 0% for DTIC. The median progression-free survival and the median survival were 4 and 9 months, respectively for DBDT, and 2 and 7 months for DTIC. DBDT was associated with significant haematological toxicity: 33% of the patients experienced a grade III or IV neutropenia and 28% a grade III or IV thrombocytopenia. In conclusion, the overall response rate obtained with DBDT was greater than that obtained with DTIC alone; however, this combination increases toxicity with limited impact on overall survival.

Cerebral metastases from melanoma are correlated with a poor prognosis. Temozolomide is an oral alkylating agent that can cross the blood-brain barrier and in phase II and III trials, patients with advanced metastatic melanoma achieved overall response rates of 13 to 21%. The present study evaluated the efficacy and toxicity of temozolomide-based chemotherapy in patients with cerebral metastases from melanoma. Twenty-five patients (median age 48 years) with histologically confirmed stage IV melanoma and cerebral metastases treated with temozolomide-based chemotherapy. 10 patients received temozolomide plus docetaxel, nine patients temozolomide plus cisplatin and six patients temozolomide as single agent. Six patients achieved an objective response (24%). All responses were partial. The disease was stable in five patients (20%) and 13 patients progressed (52%). The median response duration was 6.9 months (range 1.8 to 16 months). The median time to progression (TTP) for all patients was 2 months, compared with a median TTP of 3.9 months, among responders and a median TTP of 1.8 months, for patients who remained stable or progressed (P<0.0001). The median survival time for the entire patient population was 4.7 months. The median survival for responders was 5.5 months and for non-responders was 3.6 months. The difference was statistically significant (P<0.05). The toxicity was mild. The most frequently reported adverse event were myelotoxicity and nausea and vomiting. Four patients developed grade 3/4 leukopenia, two grade 4 neutropenia, and one patient developed grade 3 thrombocytopenia. There was no treatment discontinuation caused by toxicity. Temozolomide-based chemotherapy may have a role in patients with cerebral metastases from melanoma. Further exploration is required. Toxicity was manageable.

The addition of cytokines, such as interferon alpha-2b and interleukin-2, to chemotherapy in metastatic melanoma has produced conflicting results in phase II and III trials. We report our experience with a chemoimmunotherapeutic regimen using subcutaneous cytokines. Twenty-eight patients with advanced melanoma (median age, 45 years; male to female ratio, 19 : 9) were treated. Doses were as follows: cisplatin, 20 mg/m intravenously (iv) days 1-4; vinblastine, 1.6 mg/m iv days 1-4; dacarbazine, 800 mg/m iv day 1; interferon alpha-2b, 5 MIU/m subcutaneously (sc) days 1-5; interleukin-2, 9 MIU/m sc days 1-5 and 8-12. Treatment was repeated every 3 weeks for a maximum of six cycles. The response was assessed after two cycles and toxicity at every cycle, according to World Health Organization (WHO) and National Cancer Institute (NCI) criteria, respectively. At a median follow-up of 8 months, only four patients (14%) were still alive. The overall response rate was 33%, with three (11%) complete responses lasting for 17, 14 and >24 months. There were six (22%) partial responses and three stable disease. Amongst the responders, three patients progressed at the level of the central nervous system. The median time to progression and overall survival were 3.5 and 9 months, respectively. The most common grade 3-4 toxicity was neutropenia, reported in 25 of the 28 patients (92%). Only two patients (7%) experienced neutropenic fever. Thrombocytopenia grade 3-4 occurred in seven of the 28 patients (25%), with only one patient needing transfusional support. One toxic death due to neutropenic fever occurred. It can be concluded that the chemoimmunotherapy schedule evaluated is active and may be considered for patients with metastatic melanoma who have a good performance status and a limited disease burden.

New therapies are needed to improve the prognosis of patients with metastatic melanoma. This study evaluates the safety and efficacy of weekly paclitaxel in patients with metastatic melanoma. Patients received paclitaxel at 80 mg/m over 1 h, weekly for 3 weeks, followed by a 1-week rest period. Disease status was assessed every other cycle. Treatment was continued until patients experienced either disease progression or unacceptable toxicity. Twenty-seven patients were enrolled in this phase II clinical trial. Of these patients, two were subsequently determined to be ineligible. All patients, however, were considered to be evaluable for toxicity and all patients were included for response assessment in an intention-to-treat analysis. Patients received paclitaxel for a median of two cycles (range, <1-8). None of the 27 patients showed a response to treatment. Eight patients had stable disease. The median progression-free survival was 1.8 months (95% confidence interval, 1.7-2.5 months) and the median survival was 7.6 months (95% confidence interval, 4.7-9.7 months). The most common grade 3 toxicity was neutropenia (four patients) and one patient had grade 4 neutropenia. Other treatment-related grade 3 toxicities included hypersensitivity reaction (one patient) and diarrhoea (one patient). Of note, five patients had peripheral neuropathy; however, in each case, the neuropathy was only grade 1. Weekly paclitaxel is relatively well tolerated and can maintain disease stability for some metastatic melanoma patients. Unfortunately, the anti-tumour activity of this single-agent therapy is low and additional treatment innovations are needed.

The aim of this study was to determine the efficacy and tolerability of a biochemotherapy regimen, including low-dose subcutaneous interleukin-2 and temozolomide, in patients with metastatic melanoma. Treatment consisted of temozolomide (150 mg/m per day on days 1-5), cisplatin (20 mg/m per day intravenously on days 1-4), vinblastine (1.5 mg/m per day on days 1-4), interleukin-2 (4.5 MU/m per day subcutaneously on days 5-8) and interferon-alpha2b (5 MU subcutaneously on days 5-9, 11, 13, 15, every 28 days). Thirty-six patients were included. Patients with poor prognostic factors were not excluded. Seventeen patients (47%) had been treated previously in an adjuvant setting with interferon-alpha. Four patients (11%) had been treated previously with chemotherapy and six (17%) had been treated with other biochemotherapy regimens. The distribution by American Joint Committee on Cancer staging was as follows: M1a in two patients (6%), M1b in 11 patients (31%) and M1c in 23 patients (64%). At inclusion, seven patients (19.4%) had cerebral metastases that had previously been treated with whole brain radiotherapy. For thirty-four evaluable patients, seven (20.5%) achieved an objective response. Overall, metastatic disease was substantially decreased or temporarily stabilized in 11 patients (32.4%; 95% confidence interval, 17.4-50.5). Responses were observed for all locations. The central nervous system was the initial site of relapse in two responding patients. The median survival was 10 months. The main toxicities noted were haematological (grades 3-4): neutropenia (1.8%), thrombocytopenia (1.8%) and anaemia (1.2%). It can be concluded that this regimen is well tolerated and has a modest activity despite the poor prognosis of our patient population. The low haematological toxicity rate obtained suggests that higher doses could be tried.
