Adriamycin in the treatment of cancer.

Adriamycin is a new anticancer antibiotic with a wide spectrum of activity against solid tumours. The results obtained with this agent in 159 patients with histologically confirmed advanced metastastic malignancies are reported. Encouraging results were obtained in patients with sarcomas of bone and soft tissue (12/22). Response was also seen in mesothelioma (3/9) and lung cancer (5/15). A variety of other neoplasms was also treated and results obtained in neuroblastoma, testicular tumours, stomach carcinoma, breast cancer and nephroblastoma are reported. Treatment is discussed, with reference to response rates and toxicity. Results in 72 patients with advanced breast cancer, who received adriamycin in combination with other chemotherapeutic agents, are presented. Seventeen patients with primary liver cancer were also treated with adriamycin. To date, this is the only chemotherapeutic agent that appears to significantly improve survival times in patients with this resistant form of cancer. The prophylactic use of adriamycin against osteogenic sarcoma is also discussed.

A clinical trial of the oral form of 4'-demethyl-epipodophyllotoxin-beta-D ethylidene glucoside (NSC 141540) VP 16-213.

A clinical trial of the oral form of VP 16-213 (NSC-141540), a semisynthetic podophyllotoxin, was undertaken. In 20 patients, treatment was started at 200 mg/day p.o. for 5 days; courses were repeated after a rest period of 16 days. Five patients were treated at the same dose, repeated with only 9-day rest periods. Subsequently, 65 patients were given 300-400 mg/day for 5 days, with rest periods of 9 days between courses. The side effects encountered included anorexia, nausea and vomiting, stomatitis, diarrhea, leukopenia, thrombocytopenia, alopecia, and pruritus. Substernal discomfort with or without palpitations was reported by 18 patients; no explanation for this symptom could be found. No complete remissions (CR) were observed. Parital remissions (PR) and improvement (IMP) were seen as follows: small cell carcinoma, lung (10 patients)--2 PR, 3 IMP; adenocarcinoma, lung (4 patients)--1 PR; alveolar cell carcinoma, lung (1 patient)--1 IMP; mesothelioma (4 patients)--1 IMP; ovarian cancer (12 patients)--3 PR, 3 IMP; breast cancer (20 patients)--4 IMP; colon cancer (8 patients)--2 IMP; bladder cancer (4 patients)--2 IMP; histiocytic lymphoma (7 patients)--2 PR, 3 IMP; chronic myeloid leukemia (1 patient)--1 IMP.
