We have previously shown that the risk of major depression in patients with malignant melanoma undergoing interferon-alpha (IFN-alpha) therapy can be reduced by pretreatment with the antidepressant, paroxetine. Using dimensional analyses, the present study assessed the expression and treatment responsiveness of specific clusters of neuropsychiatric symptoms over the first three months of IFN-alpha therapy. Forty patients with malignant melanoma eligible for IFN-alpha treatment were randomly assigned to receive either paroxetine or placebo in a double-blind design. Neuropsychiatric assessments were conducted at regular intervals during the first twelve weeks of IFN-alpha therapy and included the 21-item Hamilton Depression Rating Scale, the 14-item Hamilton Anxiety Rating Scale and the Neurotoxicity Rating Scale. Neurovegetative and somatic symptoms including anorexia, fatigue and pain appeared within two weeks of IFN-alpha therapy in a large proportion of patients. In contrast, symptoms of depressed mood, anxiety and cognitive dysfunction appeared later during IFN-alpha treatment and more specifically in patients who met DSM-IV criteria for major depression. Symptoms of depression, anxiety, cognitive dysfunction and pain were more responsive, whereas symptoms of fatigue and anorexia were less responsive, to paroxetine treatment. These data demonstrate distinct phenomenology and treatment responsiveness of symptom dimensions induced by IFN-alpha, and suggest that different mechanisms mediate the various behavioral manifestations of cytokine-induced "sickness behavior."

Malignant melanoma is rapidly increasing in the United States. Metastatic disease responds poorly to currently available chemotherapy. Pyrazine diazohydroxide (PZDH) is a new agent inhibiting DNA synthesis that is active in mouse tumor models and human xenografts and lacks cross resistance with multiple standard agents. In this phase II trial, patients with no prior chemotherapy or immunotherapy for metastatic disease and performance status (SWOG) of 0-1, were treated with pyrazine diazohydroxide at a dose of 100 mg/m2/day by i.v. bolus injection over 5-15 minutes for 5 consecutive days every 6 weeks. There were 23 eligible patients entered on this trial with 74% having PS of 0 and 91% having visceral metastases. There were no confirmed anti-tumor responses. The overall response rate is 0% (95% CI 0%-15%). Median overall survival is six months (95% CI 5-8 months). The most common toxicities were hematologic and consisted of lymphopenia, thrombocytopenia, anemia, and leukopenia. Fatigue. and nausea and vomiting were the next most common toxicities. Pyrazine diazohydroxide by this dose and schedule has insufficient activity in the treatment of disseminated malignant melanoma to warrant further investigation.

Sleep difficulty is a prominent concern of cancer patients, yet there has been no large study of the prevalence and nature of sleep disturbance in cancer patients. This cross-sectional survey study examined: (a) the prevalence of reported sleep problems in patients attending six clinics at a regional cancer centre; (b) sleep problem prevalence in relation to cancer treatment; and (c) the nature of reported insomnia (type, duration, and associated factors). For three months, all patients attending clinics for breast, gastrointestinal, genitourinary, gynecologic, lung, and non-melanoma skin cancers were offered a brief sleep questionnaire. Response rate was 87%; the final sample size was 982. Mean age of respondents was 64.9 years (SD 12.5). The most prevalent problems were excessive fatigue (44% of patients), leg restlessness (41%). insomnia (31%), and excessive sleepiness (28%). Chi square tests showed significant variation among clinics in the prevalence of most sleep problems. The lung clinic had the highest or second-highest prevalence of problems. The breast clinic had a high prevalence of insomnia and fatigue. Recent cancer treatment was associated with excessive fatigue and hypersomnolence. Insomnia commonly involved multiple awakenings (76% of cases) and duration > or = 6 months (75% of cases). In 48% of cases, insomnia onset was reported to occur around the time of cancer diagnosis (falling within the period 6 months pre-diagnosis to 18 months post-diagnosis). The most frequently identified contributors to insomnia were thoughts, concerns, and pain/discomfort. In a multivariate logistic regression analysis, variables associated with increased odds of insomnia were fatigue, age (inverse relationship), leg restlessness, sedative/hypnotic use, low or variable mood, dreams, concerns, and recent cancer surgery. This study provides new information about sleep-related phenomena in cancer patients, information which will be useful in planning supportive care services for cancer patients.

Sixteen patients with stage IV melanoma, who were heavily pretreated, received 11 mg/m2/day of intravenous Irofulven for five consecutive days every 28 days. There were no objective tumor responses, although one patient exhibited stable disease after 4 cycles. The most common toxicities were grade 1/2 nausea, vomiting, fatigue, anemia, and thrombocytopenia. One patient required a dose reduction for an elevated creatinine while another patient required cessation of treatment because of acute ataxia that may have been related to Irofulven. Based upon these data, Irofulven does not demonstrate significant antitumor activity to warrant further investigation in advanced melanoma.

Twenty patients with either melanoma ( 7) or kidney cancer ( 13) were treated with outpatient bolus interleukin (IL)-2 18-22 MIU/m2 IVPB for 3 consecutive days for 6 consecutive weeks followed by a 2-week rest break (on an 8-week cycle). Patient characteristics included 16 males/4 females, eleven patients had received no prior systemic therapy, median ECOG performance status = 1, and most common disease sites being lung, lymph node, subcutaneous, bone, and liver. Two patients with melanoma (29% response rate) (95% CI: 8-64%) and two with kidney cancer (15%) (95% CI: 3-43%) have achieved partial responses. Two minor responses in kidney cancer were also seen. The most common toxicities were nausea, fatigue, rigors, fever, and myalgias/arthralgias. No cardiac events occurred, and no patients required hospitalization due to toxicity. IL-2 at this outpatient dose and schedule is well tolerated and displays some evidence of activity in melanoma and kidney cancer. Larger patient numbers are required to corroborate these response rates and to determine whether complete responses are possible.

Experimental studies have demonstrated that thalidomide (Thal), a drug developed as a sedative, has antitumoural properties. The possible antitumour mechanisms of action involve: inhibition of angiogenesis, cytokine-mediated pathways, modulation of adhesion molecules, inhibition of cyclooxygenase-2 and stimulation of immuno response. Therefore, Thal is under clinical evaluation in oncology. This paper provides an overview of the data currently available in literature regarding, in terms of activity and toxicity, the use of Thal in cancer patients. Multiple myeloma is so far the most responsive malignancy. A moderate activity has been documented in certain solid tumours: glioblastoma multiforme, renal cell carcinoma and malignant melanoma. Tolerability is generally satisfactory with peripheral neuropathy being the most relevant dose-dependent toxicity. The more frequent, but moderate side effects are: somnolence, constipation, dizziness and fatigue. More studies are needed to properly evaluate the anticancer activity of Thal alone or in combination with other anticancer treatments. Preliminary studies suggest promising results of Thal in combinations with corticosteroids and cytotoxic drugs as front-line therapy of multiple myeloma. Regarding therapy of solid tumours in the adult, combination with chemotherapy, radiation therapy and molecular-targeting compounds are under investigation.

Yondelis (ET-743) is a novel anticancer agent isolated from the marine ascidian Ecteinascidia turbinata. ET-743 possesses potent antitumour activity and a novel mechanism of action at the level of gene transcription. We conducted two sequential phase I dose escalation and pharmacokinetic studies of ET-743 given as a 1- or a 3-h intravenous (i.v.) infusion. Seventy-two adults with metastatic or advanced solid tumours received ET-743 in escalating doses between 50 and 1100 microg/m(2), initially as a 1-h infusion, and later at doses between 1000 and 1800 microg/m(2) as a 3-h infusion every 3 weeks. The maximum tolerated dose (MTD) of ET-743 was 1100 microg/m(2) for the 1-h infusion schedule and 1800 microg/m(2) when given as a 3-h infusion. Dose-limiting toxicities (DLTs) were fatigue, neutropenia and thrombocytopenia. Transient non-cumulatives grade 3-4 increase in transaminases (not considered DLT) and grades 3-4 nausea and vomiting were frequently observed. Other toxicities (maximum grade 3) included anaemia, increased lactate dehydrogenase (LDH), bilirubin and alkaline phosphatase serum levels, and phlebitis; there were no toxic deaths. One pCR (melanoma), CR (uterine leiomyosarcoma), one PR (colon stromal sarcoma) and a MR (37% tumour shrinkage, gastric stromal sarcoma) were observed. A further 9 patients with colorectal, mesothelioma, bile duct carcinoma and bladder cancer had SD which lasted for six or more treatment cycles. ET-743 pharmacokinetics were linear with the 3-h infusion schedule. The haematological and hepatic toxicities of ET-743 were dose-dependent and not cumulative. Based on the current trial, the recommended dose of ET-743 for phase II studies is 1650 microg/m(2) given as a 3-h infusion.

The aim of this study was to determine the antitumour activity and toxicity of thalidomide in patients with metastatic melanoma. Between July 1999 and July 2001, 20 patients with metastatic melanoma were enrolled into this study. Patients were required to have progressive disease following standard therapies (unless there was a known contraindication for their usage) and to be free from symptomatic brain metastases. Thalidomide was administered orally at a starting dose of 200 mg/day, with increments of 100 mg every 7 days to a maximum dose of 800 mg/day. Patients experiencing intolerable side effects had their dose reduced to the maximum tolerated dose. Response and tolerance to treatment were assessed at 4 week intervals and therapy was continued until progression of disease or development of intolerable side effects despite appropriate dose reduction. All 20 patients were assessable for response. No objective response (complete or partial remission) was observed. In seven patients (35%), stable disease with a duration of 12-32 weeks (median 16 weeks) was seen. The median time to progression for all patients was 8 weeks (range 5-32 weeks) and the median overall survival was 20 weeks (range 7-130+ weeks). Treatment was generally well tolerated. Nine patients (45%) were able to tolerate the maximal planned dose of thalidomide (800 mg/day). Constipation, fatigue, somnolence and dryness of skin or mouth were the most common side effects. Thalidomide appears to possess cytostatic activity in patients with metastatic melanoma. Further studies of thalidomide in melanoma are warranted.

Malignant melanoma metastases in the gastrointestinal tract (GIT) are found in more than 60% of autopsies on patients who have died with disseminated melanoma; however, the rate of GIT metastases detected clinically averages only 2%. This discrepancy seems to be attributed to the nonspecific symptoms and signs of GIT involvement, which include weakness, fatigue, bleeding, anemia, and abdominal pain. Sometimes a diagnosis is only made when bowel obstruction occurs. We report a case of long-term survival after surgery for multiple melanoma metastases in the gastrointestinal tract and review the relevant literature. Both our case report and the literature review demonstrate the benefits of surgery for patients with melanoma metastases in the GIT. We also stress the need for meticulous follow-up, detailed history-taking, and rapid evaluation of any vague and unclear abdominal signs and symptoms for patients with melanoma.

BBR3464, a novel tri-nuclear platinum complex, forms long-range DNA adducts and is highly potent when compared with cisplatin in vitro. Preclinical studies demonstrated activity in cisplatin-resistant tumours and tumours with mutated p53 status. Phase I & II clinical studies gave preliminary indications of activity in melanoma, pancreatic, lung and ovarian cancers. The aim of this study was to determine the efficacy and confirm the toxicity of BBR3464 when given either as first- or second-line treatment for advanced disease in patients with gastric and gastro-oesphageal adenocarcinoma. Two multicentre, open label, Gehan design studies were conducted; one study used BBR3464 as first-line and the other as second-line treatment for metastatic or locally advanced disease. Nineteen first-line and 26 second-line patients were enrolled receiving a total of 74 and 53 infusions, respectively. Initially, seven patients in the second-line study received BBR3464 using the planned schedule of 1.1 mg/m2 every 4 weeks; however, 5 of these patients experienced dose-limiting grade 3 or 4 febrile neutropenia; subsequent patients in both studies were treated using the modified schedule of 0.9 mg/m2, every 21 days. In 1 of 17 evaluable, previously untreated patients, regression of multiple skin lesions was noted with stabilisation of lung metastases and maxillary sinus mass, lasting 155 days. In the first-line study, the median time to progression was 85 days [95% Confidence Interval (CI): 42, 127] (2.8 months) and in the second-line study, the median time to progression was 71 days [95% CI: 42, 109] and 38 days [95% CI: 32, 73] in the 1.1 and 0.9 mg/m2 dose level groups, respectively. Toxicity data were available for 45 patients. Neutropenia was the main toxicity seen (G3: 40%, G4: 40%). Febrile neutropenia was observed in six patients (15%) treated with 0.9 mg/m2 compared with five patients (71%) treated with 1.1 mg/m2 BBR3464. Other drug-related toxicities (G3/4) included: anaemia, thrombocytopenia, nausea, vomiting, diarrhoea, mucositis and fatigue. Diarrhoea and nausea/ vomiting were adequately controlled by the use of loperamide and antiemetics, respectively. Recruitment to the second-line study was closed early due to the poor response rate (1/17 evaluable, 6%; 95% CI: 1%, 27%) and short time to progression noted in the first-line study. Further studies with BBR3464 in this tumour type are not recommended.
