    Notes: Abstract To evaluate toxicity and efficacy of chemotherapy in elderly patients (≥65 years of age) with advanced colorectal cancer, data from two consecutive trials conducted between 1984 and 1995 at the National Institute for Cancer Research were analysed comparing the results of treatment in those 65 years of age or older and in those younger than 65 years. Of 215 patients recruited, 82 elderly patients (median age 70 years, median performance status 1) received one of the following regimens based on 5-fluorouracil (5-FU): (1) weekly 5-FU 600 mg/m2 i.v. bolus (30 patients); (2) weekly 5-FU 600 mg/m2 bolus plus leucovorin (LV) 500 mg/m2 2-h i.v. infusion (28 patients); (3) Weekly 5-FU 2600 mg/m2 24-h continuous i.v. infusion plus LV 100 mg 4-h i.v. infusion and 50 mg orally every 4 h for five doses (24 patients). Overall, 1071 chemotherapy cycles were administered with a median number of 12 courses per patient. The main side effects were diarrhoea, observed in 38% of patients, stomatitis in 24% of patients and hand-foot syndrome in 13% of patients, and haematological toxicity affected only 15% of patients. No patient suffered grade IV toxicity. In three patients chemotherapy was discontinued because of toxicity (two patients suffered grade III diarrhoea, one patient grade III hand-foot syndrome). No significant difference in toxicity was evident between patients older than or younger than 65 years. Analysis of median dose intensity demonstrated no difference between the two groups. Overall objective response was observed in 18% (95% confidence limits 11–29) of elderly patients (15/82) in comparison with 23% (95% CL 17–32) of patients 〈65 years of age (31/133 pts). In conclusion, chemotherapy in elderly patients with advanced colorectal cancer is a safe and effective treatment with acceptable toxicity and comparable objective response rates.

    Notes: Abstract  To verify whether the association of granulocyte-macrophage colony-stimulating factor (GM-CSF) and erythropoietin (EPO) would allow both the acceleration and the dose escalation of the cyclophosphamide/epidoxorubicin/5-fluorouracil (CEF) regimen as first-line therapy in advanced breast cancer patients, we conducted a dose-finding study. Cohorts of three consecutive patients received cyclophosphamide (Ctx, dose range 800 –1400 mg/m2), epidoxorubicin (Epidx, dose range 70–100 mg/m2), and 5-fluorouracil (5-Fu, 600 mg/m2, fixed dose) given as an intravenous bolus on day 1 every 14 days; GM-CSF at 5 μg/kg given as a subcutaneous injection from day 4 to day 11; and EPO at 150 IU/kg given as a subcutaneous injection three times a week. In no single patient was any dose escalation allowed. A total of 14 patients entered the study. At the 4th dose level (Ctx 1400 mg/m2, Epidx 100 mg/m2, 5-Fu 600 mg/m2), two patients had dose-limiting mucositis and one patient developed dose-limiting neutropenia. Therefore, the 3rd cohort received the maximum tolerated dose, i.e. Ctx at 1200 mg/m2, Epidx at 90 mg/m2, and 5-Fu at 600 mg/m2, given every 18.5 (±2.5) days. Toxicity was moderate and manageable in an outpatient setting. Only 1 admission at the 4th dose level was required. Throughout the 4 dose levels there was no toxicity-related death; grade IV leukopenia ranged from 24% to 75% of cycles and grade IV thrombocytopenia ranged from 6% to 8%. No grade IV anemia was recorded. Increasing the doses of Ctx and Epidx while maintaining a fixed dose of 5-Fu with the support of both EPO and GM-CSF allows safe acceleration and dose escalation of CEF chemotherapy. Further controlled studies will evaluate the activity and efficacy of this strategy.

    Notes: Abstract In order to better explore the toxicity and the activity of high dose epirubicin (120 mg/m2, 3 weeks) we analyzed a population of 127 metastatic breast cancer patients, treated in a randomized clinical trial conducted to evaluate the cardioprotective effect of dexrazoxane against epirubicin induced cardiotoxicity. All the patients had a diagnosis of metastatic breast cancer, an ECOG performance status ≥2 and normal hematologic, renal, hepatic and cardiac function. No prior adjuvant chemotherapy including anthracycline was allowed. Epirubicin was given at the dose of 120 mg/m2 i.v. bolus every 3 weeks. One hundred twenty five patients were evaluable for toxicity and response. Seventeen patients (11%) had a complete response and 47 patients (37%) a partial response, for an overall response rate of 48%. The median progression free and overall survivals were 8.3 months and 18.3 months, respectively. Grade 3 and 4 leukopenia were observed in 8% and 7% of the patients, respectively. The most frequent nonhematological grade 3 toxicities were alopecia (87%), nausea and vomiting (16%), and mucositis (8%). Cardiotoxicity, defined as occurrence of congestive heart failure, decrease in resting left ventricular ejection fraction (L-VEF) to ≥45, or 20 EF units decrease from baseline L-VEF, was observed in 19% of the patients, after a median cumulative dose of epirubicin of 720 mg/m2 (range 120–1440). This study confirms in a large series of patients the activity of high dose epirubicin; however, the high incidence of cardiotoxicity requires a careful evaluation of cardiac risk factors before treatment.

    Notes: Abstract Background: On the basis of our previous experience, we designed this study to determine the activity and toxicity of outpatient treatment with autologous tumor-infiltrating lymphocytes (TIL) together with intermediate-dose recombinant interleukin-2 (rIL-2) and low-dose recombinant interferon alfa-2a (rIFN-α2a), for patients with metastatic melanoma. Methods: Between April 1992 and October 1994, we processed 38 melanoma samples derived from 36 patients with metastases. Proliferative cultures of expanded lymphocytes (TIL) were infused only once into patients with metastatic melanoma. rIL-2 was administered subcutaneously for 1 month, starting on the day of TIL infusion, at an escalating dose of 6–18 × 106 IU/m2/day for the first week and at the maximum-tolerated dose for the subsequent 3 weeks and then, after a 15-day interval, for 1 week/month for 3 months. rIFN-α2a was administered subcutaneously at 3 × 106 IU three times each week until progression. Results: Of 38 melanoma samples, 19 (50%) resulted in proliferative cultures and were infused. The median number of expanded lymphocytes was 18 × 109 (range, 1–43 × 109), and the median period of culture was 52 days (range, 45–60). rIL-2 was administered at doses ranging between 6 and 18 × 106 IU/m2/day. Toxicity was mild or moderate, and no life-threatening side effects were encountered. Two of 19 treated patients experienced complete responses of their metastatic sites (soft tissue), 10 had stable disease, and 7 showed progressive disease. The response rate was 11% (95% confidence interval, 2–35%). Conclusions: Outpatient treatment with TIL plus rIL-2 and rIFN-α2a is feasible, although, within the context of the small sample size, the activity of the combination was no different from the reported activity of any of the components used alone.
