The prospective controlled Phase III clinical trial tested the therapeutic value of the cis-platinum-adriamycin-cyclophosphamide combination (CAP), compared with the combination including cyclophosphamide, methotrexate, 5-fluorouracil, vincristine and prednisolone (CMFVP), in untreated metastatic breast cancer. One hundred and twenty-three patients (greater than 2 cycles) were evaluated: 61 on the CAP, and 62 on the CMFVP schedule. An objective response (CR + PR) to CAP combination chemotherapy was achieved in 72% of patients (43/61), with a high rate (36%) of complete remissions. In terms of metastatic site, the response rate appeared to be particularly high in soft tissue and visceral organ (lung, liver) metastases. In the CMFVP group, an objective response was noted in 26 of 62 patients (42%), with 16% complete remissions. The difference in overall therapeutic response - and in the complete remission rate as well - was statistically significant to the advantage of the CAP regimen (P less than 0.01). The duration of remissions was 6-28 + months (means = 14) for the CAP, and 4-15 + months (mean = 9) for the CMFVP schedule. Toxic side effects were more pronounced in the CAP group, particularly myelosuppression, with anemia prevailing. Side effects of CMFVP treatment were moderate. In 39 CMFVP previously treated cases, CAP was administered as second-line treatment, and an objective response was observed in 51% of cases (20/39). Results of this controlled trial showed the advantage of the CAP combination chemotherapy in the treatment of metastatic breast cancer.

Mitoxantrone (Novantrone; dihydroxyanthracenedione) is an anthraquinone previously shown to be active in human breast cancer. It appears to have less toxicity than doxorubicin. Results of this phase II-III randomized cross-over trial to determine the relative efficacy and toxicity of mitoxantrone in comparison to doxorubicin, are presented. Patients with measurable, recurrent breast cancer with limited prior chemotherapy with or without radiotherapy for metastatic disease, and who had not been exposed to prior doxorubicin, were randomized to receive either mitoxantrone or doxorubicin every three weeks with cross-over on progression. Response rates, duration of remission, time to treatment failure, and drug toxicity, including cardiac toxicity evaluated with serial radionuclide angiocardiography, were evaluated. Differences in the response rates for the two groups were not statistically significant. Neither time to treatment failure nor duration of response are significantly different (p greater than 0.05). With respect to toxicity, mitoxantrone treated patients consistently exhibited a lower incidence and less severe drug toxicity as compared to their doxorubicin-treated counterparts. Cardiac toxicity was carefully monitored and thus four patients on doxorubicin have had drug related congestive heart failure, as compared to none on mitoxantrone. In summary, mitoxantrone appears to be as active as doxorubicin in patients with stage IV breast cancer previously treated with chemotherapy; however, mitoxantrone causes significantly less nausea, vomiting, stomatitis and alopecia at doses which induce equal or greater myelosuppression than doxorubicin, and appears to be less cardiotoxic.

One hundred one eligible children with soft-tissue sarcomas arising within the retroperitoneal space have been registered on Intergroup Rhabdomyosarcoma Study Committee (IRS) studies I and II and followed for at least 2 years or until death. The most common presenting symptoms and signs were pain in the abdomen or lower extremities, and/or an abdominal mass, usually noted by a parent or a physician seeing the child for other complaints. The median age at diagnosis was 6.5 years and the sex ratio (M/F) 1.7:1. Histologic types were embryonal or botryoid rhabdomyosarcoma (RMS) in 58 patients, alveolar RMS in 8, pleomorphic RMS in 2, undifferentiated sarcoma in 20, extraosseous Ewing's sarcoma in 4 and unspecified sarcoma in 9. Median tumor size was 10 cm, significantly larger than the 7.5 cm noted in the IRS studies as a whole (P less than 0.05). One patient had complete tumor removal (Group I); 12 had grossly complete removal with microscopic residual tumor (Group II). Fifty-one patients had residual local tumor after biopsy or partial resection (Group III) and 37 patients had distant metastases at diagnosis (Group IV). Treatment included surgery, radiation therapy (RT) and combination chemotherapy with vincristine and actinomycin D with or without cyclophosphamide and Adriamycin (doxorubicin) according to protocol. Thirty-nine of 99 patients (39%) had major difficulties in the delivery of specified RT. Seventy patients received sufficient therapy to be evaluable for treatment response. Forty-one (58%) achieved a complete remission and 16 (23%) achieved partial remission. Twenty-four of 41 children (59%) achieving a CR have relapsed. The proportion of children who remained relapse-free at 2 and 3 years of follow-up was 44% or 42%, respectively. Overall, 40 children have developed recurrent sarcoma and the median disease-free interval and overall survival times were 54 and 88 weeks, respectively. Most children experienced severe myelosuppression; there were three early deaths from infection which occurred during granulocytopenic periods. One third of the patients experienced cystitis. Children with soft-tissue sarcomas arising in the retroperitoneal space have a poor prognosis associated with large tumors which, because of location and/or extent (Groups III or IV), are unresectable and difficult to treat.

Methylglyoxal-bis(guanylhydrazone) (MGBG), an inhibitor of polyamine synthesis, was administered to 35 patients with hormone-resistant advanced adenocarcinoma of the prostate in doses of 500 or 600 mg/m2 per week intravenously. Of 31 patients with bidimensional measurable soft-tissue lesions, 25 had an adequate trial, defined as four or more doses. Six (24%; 95% confidence limits, 8% to 32%) patients achieved a partial remission (greater than or equal to 50% reduction in tumor size) in soft-tissue disease. Response was noted to start after one to two doses and persisted for a median of three months (range, 1 to 4 months). Toxicity was tolerable, and significant myelosuppression was not observed. The lack of response in osseous metastases may be secondary to the short duration of remission or to the presence or inducibility of the enzyme ornithine decarboxylase in bone. Since some animal prostatic cancer tumor models are sensitive to cytotoxic drugs that produce polyamine inhibition, clinical trials of MGBG combined with other inhibitors of the polyamine pathway should be explored.

Forty-two patients with advanced testis carcinoma without previous chemotherapy were treated with VAB-4, and 41 were evaluable. The program consisted of three in-hospital inductions 16 weeks apart, and outpatient treatments every three weeks. Of the patients, 80% achieved complete remissions (CR). Chemotherapy alone induced CR in 61%, partial remissions (PR), in 24% and minor response (MR), in 15%. An additional 20% of patients (six PRs and 2 MRs) achieved CR following resection of residual tumor deposits. With a median follow-up of 27 months, the median duration of CR has not been reached. Of those achieving CR to chemotherapy alone, 12% had relapses. Bulk and extent of metastatic disease, histology of primary tumor, and tumor markers at the beginning of therapy influenced the frequency of CR. Of those with minimal disease, 90% achieved CR. The CR rate was 67% for those with advanced thoracic disease and 29% for those with advanced abdominal disease. Patients who had embryonal carcinoma and those who had no elevation of alpha-fetoprotein had a higher frequency of CRs. Myelosuppression with a leukocyte count drop less than 1000/mm3 occurred in three patients, and no patient had chronic renal failure or pulmonary fibrosis. One patient died from sepsis while in complete remission.

Thirty-six men with Stage III or bulky Stage II malignant germ cell tumors of the testis who received no prior chemotherapy were treated with the VAB-6 protocol without maintenance and 34 were evaluable. The VAB-6 regimen is a 3-4 month program beginning with successive inductions at 3-4 week intervals: day 1, cyclophosphamide 600 mg/m2 of body surface, bleomycin 30 mg, vinblastine 4 mg/m2 and dactinomycin 1 mg/m2 intravenously; days 1-3, bleomycin 20 mg/m2/day X 3 by continuous 24-hour intravenous infusion; and day 4, cis-platinum 120 mg/m2 intravenously. Complete responders receive a fourth induction and are followed thereafter without further chemotherapy. Incomplete responders have resection of residual disease one month after the third induction. If the resected specimen contains malignant tissue, an additional two inductions are given. Thirty-one of 34 (91%) evaluable patients achieved complete remission and 28 remain in complete remission with median follow up of 24+ months. Chemotherapy alone was most effective in patients with minimal metastatic disease, with no teratoma in primary tumor, and with pure seminoma. Patients with advanced metastatic deposits or with teratoma in the primary tumor frequently required combined chemotherapy and surgery to achieve disease free status. Myelosuppression was the principal potentially serious toxicity. With effective induction, maintenance chemotherapy is not necessary.

Forty-four patients with nonseminomatous germ cell tumors with "poor prognostic features" were entered on the VAB-5 regimen and 38 are evaluable. VAB-5 represents an intensified version of the VAB-4 protocol. Poor prognostic features were considered to be bulky metastases ( greater than 5 cm in diameter), palpable retroperitoneal disease, liver metastases, brain metastases, involvement of two or more parenchymal organs, pure choriocarcinoma, alpha fetoprotein or human chorionic gonadotropin serum levels over 1000 ng/ml, lactic acid dehydrogenase serum levels over 400 mg/dl, and failure to prior chemotherapy. Eighteen of 38 evaluable patients became free of neoplasm, 11 with chemotherapy alone, and seven with combined chemotherapy and surgery. Fourteen of 18 complete responders remain alive and free of disease with a median follow-up of 50 months. Complete remission with testis tumor occurred in 13/15 without and 5/15 with prior chemotherapy and in none of eight patients with primary extragonadal germ cell tumors. Thirty-one patients received antibiotics when they developed fever during myelosuppression. Ten patients developed transient serum creatinine levels over 2 mg/dl after cis-platinum and one required hemodialysis with subsequent recovery. All patients had severe mucositis after induction. An apparent improvement of results over prior VAB protocols in patients with poor prognostic features was compromised by significant increases in toxicity and such patients require special study to improve cure rates.

We employed human lymphoblastoid interferon (HLBI) in the treatment of 4 cases of renal carcinoma with pulmonary metastases. All of the cases were males aged 58 to 62. On initial examination, it was revealed that all 4 cases already had multiple metastatic lesions in the lung as well as in other organs such as brain and bone. HLBI was injected i.m. daily at a dosage of 6 X 10(6) units. Treatment was continued for 33 to 119 days, with the total dose being 198 X 10(6) units to 714 X 10(6) units. As to tumor response, minor response was obtained in 1 case, no change in 2 cases, and progressive disease in 1 case. In the case in which minor response was obtained, the size of the pulmonary metastases had reduced by 30% after 8 weeks of treatment with HLBI. As side effects, we observed fever in all cases, and also, anorexia, general malaise, asthenia, and myelosuppression. However, none of these symptoms were serious enough to require discontinuation of HLBI medication. From the results obtained in our own cases, we believe that HLBI may become a new antitumor agent effective for renal cell carcinoma.

Twenty-three patients with advanced measurable gastric cancer were treated with FAM-chlorozotocin in an attempt to demonstrate improvement in rate and duration of response over FAM (5-fluorouracil, Adriamycin and mitomycin C). Six (26%) partial responses were recorded with a median duration of two months. FAM-chlorozotocin was well tolerated with moderate myelosuppression as the major dose-limiting toxicity; the leukocyte nadir was 3.0 X 10(3)/mm3 (range, 0.9-6.0) and the platelet nadir was 100 X 10(3)/mm3 (range, 45-100). The authors were unable to find significant differences in prognostic factors such as performance status, sites of metastatic disease, intensity of therapy to account for the discrepancy in response rates between FAM (42%) and FAM-chlorozotocin (26%).

Eighteen patients with unresectable bronchogenic carcinoma were treated with amphotericin B (7.5 mg/m2 on day 1, 15 mg/m2 on day 2, and 30 mg/m2 on days 3 and 4) plus BCNU (250 mg/m2 on day 4 following amphotericin B) with courses of therapy repeated every 8 weeks. All patients had metastatic disease, and 5 had received prior chemotherapy. Antitumor responses were observed in 8 patients. Six patients had partial responses (greater than 50% decrease in tumor area): 1 of 3 with small cell undifferentiated carcinoma, 1 of 4 patients with large cell undifferentiated carcinoma, 2 of 7 patients with adenocarcinoma, and 2 of 4 patients with epidermoid carcinoma. Two patients had objective improvement (25--50% decrease in tumor area): 1 with small cell undifferentiated carcinoma and 1 with epidermoid carcinoma. The median duration of remission was 3 months. The median duration of survival was 7 months for patients achieving partial response, and only 2 months for other patients. Myelosuppression was the dose limiting toxicity. One patient died with hepatocellular dysfunction, possibly related to BCNU. Transient hypotension was observed in 2 patients. We conclude that amphotericin B plus BCNU produced an encouragingly high response rate in patients with bronchogenic carcinoma, and that a randomized phase III trial is warranted to determine whether amphotericin B enhances the antitumor effects of nitrosoureas or other known antitumor agents.
