Eighteen patients with non-small cell lung cancer were entered into a phase II protocol of oral 4-demethoxydaunorubicin. All were evaluable for toxicity and 17 for response. The major toxicity was hematologic with eight patients developing an ECOG grade 3 or 4 toxicity. There were no responses to the treatment

A bolus intravenous dose of 5-fluorouracil of 600 mg/M2 was added exactly 1 hour after methotrexate administration in an established combination program including bleomycin and cisplatin for advanced squamous cell cancer of the head and neck. Results were no better than those observed previously with the three drugs, and hematologic and mucosal toxicities were slightly worse. The overall response rate was 41% in 34 patients with recurrent or metastatic disease, with only 6% complete remissions. Median time to disease progression for responding patients was 14 weeks, compared with 10 weeks for nonresponders. Partial response had little impact on survival. Among 12 patients with far-advanced disease confined above the clavicles without prior radiotherapy, 9 (75%) achieved partial remission, but the median survival, even with later surgery or irradiation, was only 34 weeks

Prior to 1974 gastric cancer was considered refractory to chemotherapy. Single agent 5-Fluorouracil, mitomycin, and the nitrosoureas produced modest response rates with no augmentation of survival as compared to historical controls. Combinations of these agents produced slight increases in survival. The addition of doxorubicin, which had no major impact as a single agent, to 5-Fluorouracil and mitomycin C in 1974 produced impressive response rates over 40%, although these early optimistic results were tempered in randomized multi-institutional trials. Nevertheless, median overall survivals appear to have increased with this regimen over historical controls, and the substitution of cisplatin or methyl-CCNU for mitomycin C in Phase II trials has produced equivalent results. Comparison with historical controls is problematic as it is unknown what role more aggressive surgery and supportive measures may have played in increasing survival. Encouraging results with combination therapy in advanced gastric cancer have suggested opportunities to employ combination chemotherapy as adjuvant therapy or together with radiation for locally advanced gastric cancer. The role of less cardiotoxic derivatives of doxorubicin remains to be more fully explored.

As of August 1984, 115 women with advanced breast cancer have been randomized to receive a combination of either cyclophosphamide, Novantrone (mitoxantrone) and 5-fluorouracil (CNF) or cyclophosphamide, Adriamycin (doxorubicin) and 5-fluorouracil (CAF). Seventy-one percent of all patients were post-menopausal and 44% of CNF patients and 57% of CAF patients were estrogen receptor (ER) negative. Slightly over 30% of all patients had received hormonal therapy or chemotherapy in an adjuvant setting. Hematologic toxicity was similar in regard to platelet counts but slightly lower nadirs were experienced with CNF therapy than with CAF. However, there were fewer dosage decreases with CNF. Significantly less nausea and vomiting were observed with the CNF regimen compared to CAF. Moreover, alopecia was reduced appreciably in patients who received CNF. The response rate to CNF for the first 38 eligible and evaluable patients was 42%, and for 53 eligible and evaluable patients who received CAF the response rate was 45%, a non-significant difference. Median response durations were similar also, 140 days for CNF and 168 days for the CAF regimen. Time to treatment failure was similar for both regimens. CNF is an effective regimen for patients with advanced breast cancer, with less toxicity than CAF.

Thirty patients with advanced refractory breast cancer received bisantrene 260 mg/m2 intravenously every 3 weeks. Reversible myelosuppression was the most commonly observed side effect. Four patients (13.3%) achieved objective partial response (90% confidence intervals 3-24%), while two patients (6.6%) had disease improvement with a PR + IMP rate of 19.9%. Seven additional patients (23.3%) had stabilization of disease. This drug has antitumor activity against breast cancer and warrants further study, particularly if problems with drug delivery are overcome.
