The combination of chemotherapy and immunotherapy seems to improve response rate in metastatic melanoma. We investigated the effects on toxicity and immunological effects of a single dose of dacarbacin (DTIC; 850 mg/m2) or cisplatin (CDDP; 100 mg/m2) added to subsequent immunotherapy with interferon-alpha (IFN-alpha) and interleukin-2 (IL-2). Twelve patients, who did not respond to IFN-alpha/IL-2 alone were studied. Six received DTIC and IFN-alpha/IL-2, and six received CDDP and IFN-alpha/IL-2. DTIC did not add significant toxicity except for nausea. Significant thrombocytopenia was observed in two patients after CDDP. Although CDDP led to grade 3 nephrotoxicity in two patients, the IL-2-induced fluid retention was less severe than with IFN-alpha/IL-2 alone. Pharmacokinetics of IL-2 were not altered by DTIC, but higher IL-2 serum levels were found in patients with grade 3 nephrotoxicity after CDDP. The IL-2-related induction of secondary mediators (interferon-gamma, tumour necrosis factor-alpha, soluble CD25) was not impaired by chemotherapy and the induction of neopterin was significantly higher after addition of CDDP. One partial response was observed after addition of DTIC to IFN-alpha/IL-2, and one after addition of CDDP. The addition of a single dose of DTIC or CDDP to IFN-alpha/IL-2 is fairly well tolerated and does not abolish induction of secondary mediators. Randomized trials are necessary to test the clinical efficacy.

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)

The therapy of metastatic melanoma is limited by poor responses to known chemotherapeutic agents. The report of Mulder et al. (Proc ASCO 1992; 11: 347) raised the possibility of the known interaction between 5-fluorouracil and interferon-alpha2a improving response rates in melanoma. This study was designed to examine the effects of 5-fluorouracil plus interferon-alpha2a alone without the confounding effects of dacarbazine. Doses were chosen based on the earlier study rather than the higher doses used in colon cancer. Therapy for metastatic melanoma with 5-fluorouracil and interferon-alpha2a is manageable in terms of toxicity. The major toxicities were lethargy, nausea/anorexia and flu-like symptoms. These were thought to be primarily attributable to interferon-alpha2a. Only one case of severe diarrhoea occurred. The response rate of 14% is similar to the reported results of interferon-alpha2a treatment alone. On these data, there is no evidence of synergy using this dose and schedule.

The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is characterized by hyponatraemia due to water retention resulting from the persistent release of antidiuretic hormone (vasopressin). It may occur in a variety of malignant and non-malignant conditions, in particular in association with oat cell carcinoma, pulmonary and cerebral diseases. We report the case of a male patient affected by melanoma of the right temporal region with brain metastasis who developed acute headache, drowsiness, nausea, vomiting and pathological reflexes. Clinical and laboratory investigations led us to the diagnosis of SIADH. Restriction of fluid intake obtained a good clinical improvement with normalization of laboratory alterations; after 2 months the patient experienced a new episode of SIADH which was promptly treated. As melanoma has been occasionally observed in association with SIADH it should be included in the list of tumours that can cause this particular syndrome.

Inspired by the high response rates achieved with the DBCT regimen (dacarbazine [DTIC], carmustine [BCNU], cisplatin and tamoxifen [TAM]), we administered the nitrosourea compound fotemustine, cisplatin and TAM (FCT regimen) to 69 patients with metastatic melanoma. Fotemustine (100 mg/m2) and cisplatin (100 mg/m2) were administered every 4 weeks, preceded by TAM 160 mg daily for 7 days from the second course onwards. Pharmacokinetic blood sampling was performed in 14 patients during the initial two cycles to compare the pharmacokinetic behaviour of fotemustine with or without TAM. Previous chemo- or radiotherapy was allowed, and patients with brain metastases or concomitant other malignancies were included. Four complete and 11 partial responders were observed among 66 evaluable patients, yielding a response rate of 22.7% (95% confidence interval 12.9 32.5%). The median survival time was 6.4 months (range 0.1-52+ months). The main toxicities were thrombocytopenia, protracted nausea/vomiting and ototoxicity. Renal toxicity was generally mild, but possibly contributed to two deaths. Seven patients experienced deep venous thrombosis during the study. TAM had no influence on the pharmacokinetics of fotemustine. The activity of the FCT regimen was clearly inferior to that initially reported with DBCT treatment. However, a recent publication concludes that the latter achieves a considerably lower response rate when administered to a larger patient group. We believe our results reflect the true activity of FCT and similar regimens when administered routinely to unselected patients. Considering the number of potentially serious side effects, we cannot recommend the moderately active FCT regimen as a palliative treatment option for melanoma patients.

Melanoma is an uncommon disease in Japan. The incidence, however, has been gradually increasing in the last two decades, as in many other countries worldwide. Ten patients with metastatic malignant melanoma were treated between March of 1997 and April of 1998 in the Department of Dermatology, National Cancer Center Hospital, with a combination chemotherapy consisting of dacarbazine (DTIC), nimustine hydrochloride (ACNU), cisplatin (CDDP), and tamoxifen (TAM). The patients characteristics were as follows: four were males and six females; the age range was 33-70 years; all were Japanese; sites of primary disease: extremities 4, primary unknown 3, nasal cavity 1, anus 1, scalp 1; sites of metastases: lymph nodes 6, pulmonary system 5, skin 2, liver 3, gall bladder 1, adrenal gland 1. The chemotherapy regimen included DTIC 220 mg/m2/i.v. on days 1 through 3, ACNU 60 mg/m2/i.v. on day 1, cisplatin 25 mg/m2/i.v. on days 1 through 3, and tamoxifen 10 mg p.o. twice daily. One patient achieved a complete response and 3 showed partial responses. The response rate was 40%. The four responders included those with metastases to the nodes, lung, and liver. The main toxicities were nausea, vomiting, leucopenia, anemia, and thrombocytopenia. This regimen is a fairly effective combination against metastatic melanoma.

Reduced glutathione (GSH) production by tumour cells has been proposed as a mechanism for resistance to alkylating agents. High levels of paracetamol can deplete intracellular GSH. We conducted a phase I trial of high dose paracetamol and carmustine (BCNU) in patients with advanced malignant melanoma to determine the optimal biological dose and the maximum tolerated dose (MTD) with the goal of increasing sensitivity to BCNU by GSH depletion. Groups of three to five patients received escalating doses of paracetamol (10, 15 or 20 g/m(2)) every 3 weeks. Every other cycle, BCNU (10 mg/m(2)) was given 6.5 h after administration of paracetamol and 45 min before a 20 h infusion of N-acetylcysteine. Once the MTD for paracetamol had been determined, the dose of BCNU was sequentially escalated in subsequent cohorts to 150 mg/m(2). GSH levels were measured in peripheral blood mononuclear cells (PBMCs) and, when available, in tumour biopsies. The MTD of paracetamol was 15 g/m(2). The dose of BCNU was safely escalated to 150 mg/m(2). The most common toxicity was grade II nausea/vomiting. At 15 g/m(2), peak paracetamol levels (median 253 microg/ml) were reached between 1 and 4 h. No changes in GSH levels in PBMCs were seen. There were two partial responses, including a dramatic decrease in hepatic metastases. Treatment of melanoma patients with paracetamol (15 g/m(2)) every 3 weeks and BCNU (150 mg/m(2)) every 6 weeks is safe. The observation of two partial responses has led to a phase II study to evaluate treatment with high dose paracetamol alone or in combination with BCNU.

The Kirkwood high-dose interferon-alpha2b adjuvant therapy in high-risk-of-recurrence melanoma patients (stage IIb-III) demonstrated a benefit in terms of disease-free survival (DFS) (three trials out of three) and overall survival (OS) (two trials out of three). These important and exclusive results match with a grade 3-4 toxicity in about 75% of patients. This problem is the most limiting of this treatment. The aim of the study was to check these results and the feasibility of this treatment using the original Kirkwood schedule of 52 weeks, with appropriate dose modification, until unacceptable toxicity or progression of disease. From 23rd February 1998 until 29th July 2002, 26 patients were treated (mean age 45 years; range 25-70) with high-dose interferon-alpha2b adjuvant therapy. All patients were evaluated for toxicity, whilst 24 out of 26 (92%) were evaluated for OS and DFS. All patients were in stage IIB/III of the new American Joint Committee on Cancer (AJCC) classification. The sentinel node biopsy was performed in 19 out of 26 (73.1%) patients (clinical N0). At 31st December 2002, 20 out of 26 (77%) were still alive, whilst four (15%) had died and two (8%) were lost to follow-up. Of the patients still alive, 14 (70%) were disease free. The patients lost to follow-up refused to continue therapy for toxicity related treatment: one of them was disease free, whereas one was relapsed. There were 11 observed relapses (44%). The DFS ranged from 2 to 27 months. Among the patients, the maximal DFS is, at the time of writing, 59 months. The DFS mean is 29 months, the median is 19 months. The OS calculation will be performed at the end of 5 years observation. Now our attention is on therapy tolerability. In 18 patients out of 26 (69%) we noted at least one grade 3-4 toxicity, in accordance with literature data. The most common toxicities were haematological, hepatic, fever and asthenia. Overall, only two grade 4 events (one hepatic and one haematological) were reported. Grade 3 toxicity was hepatic in 23% of patients and haematological in 50%. Grade 2 toxicity was hepatic in 19%, haematological in 27% and fever in 50%. Grade 1 toxicities were hepatic, haematological and fever in 15, 15 and 35% of patients, respectively. Asthenia was severe in 54%, mild in 31% and not found in 15%. In 39, 4 and 15%, respectively, we have reported no hepatic, haematological or fever events. Less common toxicities were nausea, diarrhoea, headache, arthralgia, alopecia and one case of hypothyroidism. As a result of these reported toxicities, of 23 patients evaluable with regard to the protocol, 12 underwent dose reductions, six suspended treatment for disease progression, eight delayed treatment for toxicity, two interrupted treatment indefinitely for unacceptable toxicity or refused treatment, two refused to continue, two patients had no delay in treatment and three did not receive any delay or dose reduction. Of three patients still in therapy, just one has so far received a delay in treatment. Overall, only four patients (17%) interrupted therapy for toxicity related events, whereas 83% continued with the expected program: 52 weeks of therapy with appropriate dose modifications.

Melanoma is now the fifth most common type of cancer in North America. At present, there is no optimal treatment for this cancer. However, the lowering of the tyrosine level can inhibit the growth of melanoma. Unfortunately, this diet restriction cannot be humanly tolerated and causes vomiting, nausea, and severe body weight loss. To prevent these problems, we are studying a new approach involving the preparation intermolecularly crosslinked hemoglobin and tyrosinase for intravenous injection. In this article we describe the method of preparation and the structural and functional properties of polyhemoglobin-tyrosinase. We evaluate the effects of varying glutaraldehyde ratio, crosslinking time, and enzyme concentration on the enzyme activity of polyhemoglobin-tyrosinase. We also optimize the molecular weight distribution of polyhemoglobin-tyrosinase. The stability of polyhemoglobin-tyrosinase at 37 degrees C is much more stable when compared to noncrosslinked tyrosinase solution. Animal studies show that a higher degree of polymerization correlates with a longer circulation time of polyhemoglobin-tyrosinase, and the optimal crosslinking time is 24 hours. One intravenous injection of polyhemoglobin-tyrosinase lowers the plasma tyrosine to about 10% of its original level within one hour.

Melanoma is an increasingly common fatal skin cancer. Many groups are carrying out research on potential treatments for melanoma. One of these approaches has shown that lowering tyrosine can inhibit the growth of melanoma in cell cultures and of B16BL6 melanoma in mice. However, humans cannot tolerate tyrosine-restricted diets for lowering tyrosine because of nausea, vomiting and weight loss. We report here our preparation and characterization of a novel soluble polyhaemoglobin-tyrosinase complex. This preparation prevents native tyrosinase from having adverse effects and from rapid removal after injection. The preparation inhibited murine B16F10 melanoma cell growth in culture and delayed its growth in a mice model. Intravenous injection of the preparation lowers the systemic tyrosine level without causing adverse effects such as vomiting and weight loss in mice. It is therefore possible that this complex could be useful in the treatment of human melanoma.
