Thirty-three patients with multiple myeloma (11 untreated, 15 refractory and seven relapsed patients) have received vincristine and adriamycin infusion therapy with oral dexamethasone (VAD). The median number of course received was five. In addition 16 patients with lymphoid malignancy have received a median of four courses of VAD. Three patients who relapsed after VAD have received further VAD therapy making 52 patient treatments assessable for toxicity. Ten per cent had nausea, 4 per cent vomiting, 4 per cent total alopecia, 25 per cent constipation, 33 per cent paraesthesiae, 8 per cent proximal myopathy, 33 per cent dyspepsia, 23 per cent proven bacteraemia, and 19 per cent chest infections. Infections were not usually associated with neutropenia. Shingles was seen in four patients with myeloma, but none of the patients with lymphoid malignancy. The response rate in myeloma was 9/11, for previously untreated patients, 3/7 for relapsed, and 8/15 for refractory patients. Responses have been seen in other lymphoid malignancies-1/2 patients with relapsed acute lymphoblastic leukaemia had a complete remission. Two out of seven patients with chronic lymphocytic leukaemia achieved a partial remission, and a further three had a clinical improvement. Three out of six patients with non-Hodgkin lymphoma and one patient with macroglobulinaemia achieved a partial remission.

Seventy-four patients with rheumatoid arthritis were treated with sulphasalazine. There was a significant improvement in clinical score, with substantial falls in serum C-reactive protein concentrations and erythrocyte sedimentation rate four weeks after starting the drug. Improvement was maintained in the 38 patients who remained on the drug for one year. The mean Rose-Waaler titre did not change. There was little difference between the results in seropositive and seronegative patients. The commonest adverse effect was dyspepsia, but five patients developed a megaloblastic anaemia and one patient neutropenia; all made a complete recovery. The results suggest that the drug has a disease-modifying action not attributable to its "salicylate" content. The mode of action might be by an antibacterial effect on gut flora.

Nine patients with poor-prognosis, alkylator-refractory stage III multiple myeloma (MM) were treated with a 23-h continuous infusion (CI) of a compatible mixture of vincristine (VCR) and epirubicin (EPI) daily for 4 days along with a daily 1-h infusion of high-dose methyl prednisolone (MP) to total of 5 days (VEMP); cycles were repeated every 2 weeks when possible, usually on an outpatient basis. WHO grade 3 or 4 neutropenia and infection were the predominant toxicities encountered, necessitating some treatment delays and dose reductions. Two patients died during treatment. Peripheral neuropathy necessitated discontinuation of the VCR in six patients without obvious loss of efficacy of the regimen. Skeletal muscle dysfunction and cardiomyopathy did not occur; trivial ECG abnormalities occurred during a minority of infusions but were of indeterminate relationship to the chemotherapy. Confusion occurred in two patients; alopecia was frequent but reversible, and mild/moderate dyspepsia and stomatitis were common but easily managed. Eight patients achieved a partial response (PR); another patient experienced early death during his second cycle before response assessment. The median survival from the first VEMP administration was 9 months (range, 1-64 + months), the median response duration was 7 months (range, 1-64 + months). Two patients experienced responses too short to be clinically relevant (< or = 2 months). An analysis of weekly paraprotein estimations suggests that the intended bi-weekly cycle length may be optimal. Six of these nine patients derived major benefit from this bi-weekly regimen, which deserves further exploration.

Ticlopidine is a thienopyridine derivative which reduces the risk of reversible ischaemia and stroke in patients who have previously experienced a cerebral ischaemic episode. In comparison with aspirin, ticlopidine produced a significant reduction in the risk of stroke in a multicentre clinical trial involving more than 3000 patients with previous transient or persistent minor ischaemia, and was superior to placebo for the prevention of stroke recurrence in more than 1000 patients who had experienced a major thrombotic stroke. The cost-utility ratio for ticlopidine in comparison with aspirin was estimated to be $US31 200 to 55,000 per quality-adjusted life-year gained. Diarrhoea is the most common adverse event in ticlopidine recipients (20 to 22% incidence versus about 10% with placebo), although skin rash, nausea, dyspepsia, bleeding events, abnormal liver function and haematological disturbances were also observed in clinical trials. Severe neutropenia is the most serious event: this developed in 0.85% of patients receiving ticlopidine in 2 large clinical studies (n = 4098) but resolved after treatment withdrawal. Fatal neutropenia, although rare, has been reported in some patients receiving ticlopidine. Thus, ticlopidine is effective in reducing the risk of recurrent cerebral ischaemia and stroke. It appears to provide a gain over aspirin for the prevention of stroke after reversible ischaemia, particularly during the first year of treatment (when the risk of stroke is greatest), although further data on its absolute relative benefit would be useful. The extent to which ticlopidine is prescribed will probably depend on individual clinicians' perception of its risk/benefit and cost-effectiveness profiles. Ticlopidine is likely to be particularly useful for stroke prophylaxis in patients who do not tolerate aspirin or who have an ischaemic episode during aspirin treatment, and for the prevention of stroke recurrence in patients who have previously experienced a major stroke.

CI-980 is a synthetic mitotic inhibitor that binds to the colchicine binding site of tubulin. It demonstrates broad activity against human and murine tumor models and shows no cross resistance with tumor models whose mechanism of resistance is mediated by P-glycoprotein (MDR-1). A phase I study was completed in 25 patients with solid tumors using a 24-hour infusion schedule, with courses repeated every 3 weeks. Eight dose levels were tested between 1.2 and 15.6 mg/m2. The maximum tolerated dose was 14.4 mg/m2. Neutropenia was dose-related but not dose-limiting; thrombocytopenia was infrequent. CNS toxicities were dose-limiting and consisted of dizziness, headache, loss of coordination, loss of consciousness, nervousness, and other symptoms. These events occurred near the end of the infusion and were reversible, usually within 24 hours. One patient who was to be treated at dose level 8 (intended dose was 19.2 mg/m2; actual dose was 15.6 mg/m2) became encephalopathic prior to completion of the infusion. Other adverse events included gastrointestinal toxicities (nausea, vomiting, anorexia, constipation, stomatitis, dyspepsia, bleeding, cheilitis), IV site erythema, fever, and fatigue. A partial response was observed in one patient with colon cancer and reductions in CA-125 levels were observed in 2 patients with ovarian cancer. Pharmacokinetics were linear and dose-proportional. Results indicate high systemic clearance and wide tissue distribution. Mean pharmacokinetic parameter values: T1/2 = 5.52 hours, plasma clearance 1163 mL/min/m2, and Vdss 376 L/m2.

In the present study, we examined the appropriate schedule of S-1 medication in the combination with radiation by investigating the safety, the clinical efficacy, and antitumor effects on tumors in nude mice. In the patients with oral squamous cell carcinoma (OSCC), S-1 was given orally according to a 4-week application followed by 2-week rest regimen (4-week regimen), or a 2-week application followed by a 1-week rest regimen (2-week regimen). Radiation was given (2 Gy/day; 5 days/week) for a total of 60 Gy. In nude mouse models, human oral cancer cell lines were used as subcutaneous xenografts in nude mice. The mice were treated by S-1 (10 mg/kg) and radiation (1 Gy) with a 4-week regimen or a 2-week regimen. Apoptotic cells were detected by TUNEL method. In the patients with OSCC, the response rate with the 4-week regimen was 100% and the response rate with the 2-week regimen was 92.3%. However, a high frequency of adverse effect was found in the 4-week regimen when compared to the 2-week regimen. Grade 3 toxicity of leukopenia, neutropenia and stomatitis were seen in 3 cases, grade 3 toxicity of anorexia and nausea were seen in 2 cases, and grade 3 toxicity of decrease of hemoglobin level, heartburn/dyspepsia and increase of bilirubin level were seen in a case of the 4-week regimen. On the other hand, grade 3 toxicity of stomatitis, anorexia, nausea, heartburn/dyspepsia and increase of bilirubin level were seen in a case of the 2-week regimen. In nude mouse models, the 2-week regimen was more effective than the 4-week regimen. In addition, significant increase in the percentage of apoptotic cells was observed in the tumors treated with the 4-week regimen when compared with the tumors treated with the 2-week regimen. No loss of body weight was observed in mice treated with the 2-week regimen during the experimental period. These results suggested that the 2-week regimen might reduce adverse effects, and enhance therapeutic effects compared to the 4-week regimen. Briefly, this 2-week regimen may be a useful concurrent chemo-radiotherapy improving the quality of life (QOL) of patients with OSCC.
