The objective of this trial was to evaluate the activity and tolerability of biomodulation of 5-fluorouracil by leucovorin, methotrexate, and platinum in patients with advanced measurable disease. Thirty-five patients with histologically or cytologically proven adenocarcinoma of the pancreas were treated with methotrexate (100 mg/m2 in 500 ml 5% dextrose in a 2-hour infusion, day 1), 5-fluorouracil (800 mg/m2/day, i.v. in continuous infusion from days 2 to 5) plus 1-leucovorin (7.5 mg/m2 given per os every 6 hours, from days 2 to 5) and platinum (60 mg/m2 i.v., day 2), every 28 days. Four partial responses (12%; exact 95% confidence interval: 1-23%) were obtained in 34 evaluable patients with a median survival time of 49 weeks (range, 20-77 weeks). Ten (29%) of 34 patients had stable disease. Median time to treatment failure from the beginning of therapy was 11 weeks (range, 4-59 weeks) and median survival time was 20 weeks (range, 4-77 weeks). The most common grade III-IV toxicities were diarrhea (15%), stomatitis (41%), and vomiting (17%). Hematologic toxicity was mild. There were no therapy-related deaths. In conclusion, this trial did not report an increase or improvement in response rate and survival rates, and this regimen cannot be recommended as effective therapy for advanced pancreatic cancer.

The activity of lonidamine (a derivative of indazole-carboxylic acid and a new drug with a characteristic antitumor activity) was evaluated In non-small-cell lung cancer (NSCLC). Twenty-five patients with NSCLC with or without prior treatment received lonidamine at the dose of 450 mg/daily p.o. up to progression. Objective responses obtained were: 3 (12%) partial responses and 3 (12%) minor responses with a mean duration of 13.7 weeks for partial responses. Mean duration of treatment was 20 weeks (range 4-97+). During to the drug's characteristics, bone marrow toxicity was not observed; myalgia and mild testicular pain were the most significant side effects.

In 1990 the Italian Non-Hodgkin's Lymphoma Cooperative Study Group (NHLSG) started a multicenter study on the role of interferon (IFN) in multiple myeloma (MM). The schedule of treatment was based on the assumption that melphalan plus prednisone (MP) would be better for good-prognosis patients, whereas poor-prognosis patients would benefit from polychemotherapy. Accordingly, IFN was included randomly for the induction treatment of good-prognosis patients and randomly as maintenance of the response achieved in both groups. Up to now 78 patients of the 124 enrolled have completed the induction treatment and are evaluable for response and response duration. The overall response rate was 59%. Sixty-two percent of good-prognosis patients obtained objective response, 9/14 (64%) with MP and 9/15 (60%) with MP+IFN. Up to now, with a median follow-up of 9 months from the evaluation of response, no difference has been recorded between the maintenance and no maintenance groups on relapse rate, neither in good- nor in poor-prognosis patients.

Aim This phase II trial evaluated the biomodulation of 5-fluorouracil (5-FU) plus folinic acid (FA) with or without ifosfamide (IFO) in chemotherapy-naive patients with colorectal cancer. Patients and methods Forty-eight patients were randomized to receive: FA (25 mg/m2 iv bolus days 1 to 3), followed by 5-FU (750 mg/m2 iv bolus days 1 to 3), arm A; or FA (25 mg/m2 iv bolus days 1 to 3), followed by 5-FU (750 mg/m2 iv bolus days 1 to 3) plus IFO (2,000 mg/m2 in 1000 mL 5% dextrose in a 2-hr infusion, days 1 to 3), arm B. Mesna was added during and after IFO to prevent hemorrhagic cystitis. Treatment was repeated every 21 days in both arms. Results Forty-five patients were assessable for response: in arm A, 5 patients achieved a partial response (overall response, 25%), and in arm B, 2 patients achieved a complete and 1 a partial response (overall response, 12%). Time to failure was 3.5 months (range, 1–38) in patients treated with 5-FU plus FA, and 3 months (range, 1–21) in patients treated with the IFO combination. The median survival time was 13.5 months (range, 1–49 months) in arm A and 16 months (range, 1–43 months) in arm B. Diarrhea, stomatitis and vomiting were the most common nonhematologic toxicities in both arms. The most notable hematologic toxicity was leukopenia; 15% and 20% of patients experienced grade 4 in arm A and arm B, respectively. Conclusions IFO does not increase the activity of the 5-FU plus FA combination in advanced colorectal cancer.
