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.

A phase II study of 5'-DFUR was conducted in uterine cervical cancer and ovarian cancer by the cooperative study group consisting of 26 institutions. Forty-four cases with uterine cervical cancer and 40 cases with ovarian cancer were enrolled. A daily dose of 800-1,200 mg was administered orally for more than 8 weeks. In 34 evaluable cases with uterine cervical cancer, the overall efficacy rate was 20.6%: CR was shown in 2 cases, PR in 5 cases, MR in 2 cases, NC in 17 cases and PD in 8 cases. Histologically, the response rate was 27.3% in large cell non-keratinizing type, 20.0% in small cell non-keratinizing type and 15.4% in keratinizing type of squamous cell carcinoma. The overall response rate was 20.7% in squamous cell carcinoma, while 25.0% in adenocarcinoma. In 31 evaluable cases with ovarian cancer, the overall efficacy rate was 16.1%: PR was shown in 5 cases, MR in 3 cases, NC in 11 cases and PD in 12 cases. Histologically, the response rate was 16.7% in serous cystadenocarcinoma, 25.0% in endometrioid adenocarcinoma and 33.3% in undifferentiated carcinoma. No responses were observed in cases with mucinous cystadenocarcinoma, clear cell adenocarcinoma, mature cystic teratoma with malignant transformation and mesodermal mixed tumor. Some adverse effects were observed in 43.2% (32 out of 74 cases evaluated for adverse effects), but those of grade 4 were not observed. Most of them were gastro-intestinal disturbances such as diarrhea and anorexia. Diarrhea of grade 3 was observed in 12.2% and anorexia of grade 3 in 5.4%. Severe myelosuppression or hepatic toxicity was not observed. These results suggested that 5'-DFUR is a useful anticancer drug against uterine cervical cancer and ovarian cancer.

A late phase II study of CPT-11, a new derivative of camptothecin, in uterine cervical cancer and ovarian cancer was carried out by a cooperative study group at 26 institutions. Out of 144 patients enrolled, total cases were 110, involving 55 uterine cervical cancers and 55 ovarian cancers. In uterine cervical cancer, 5 cases of complete response (CR) and 8 cases of partial response (PR) were observed, with a response rate of 23.6% and a CR rate of 9.1%. In ovarian cancer, 13 cases of PR were observed, response rate was 23.6%. Both in uterine cervical cancer and ovarian cancer, the 95% confidence interval of response rate was 12.4-34.8%. In cases having undergone previous chemotherapy including platinum, derivatives, the response rate in ovarian cancer was 23.1% (12/52). In cases of uterine cervical cancer having previous radiotherapy, the response rate was 26.8% (11/41). In ovarian cancer of various histological types, a response was observed for not only serous cystadenocarcinoma but also mucinous cystadenocarcinoma, etc. A response was observed in distant metastatic lesions such as lung metastasis as well as primary lesion in uterine cervical cancer and ovarian cancer. Major adverse reactions were leukopenia, nausea and vomiting, diarrhea and anorexia, and these incidences (grade 2 or more) were 87.3, 60.3, 44.0 and 67.2%, respectively. Since some patients experienced severe adverse reactions, caution should be taken in treatment with CPT-11. Besides these reactions, alopecia was observed (33.1%), but severe adverse reactions such as nephropathy were not found. No significant difference in the efficacy and adverse reactions were observed between administration methods; A, 100 mg/m2 once weekly and B, 150 mg/m2 once every 2 weeks. Both were thought to be clinically useful. These results suggest that CPT-11 is clinically effective against uterine cervical cancer and ovarian cancer.

Altretamine is a National Cancer Institute-designated group C antineoplastic agent used in the treatment of advanced ovarian cancer. Altretamine is a highly lipid-soluble drug available only for oral administration as a capsule. The drug is activated through metabolic oxidation to intermediate methylol derivatives and formaldehyde. It is unclear which metabolite is the major species responsible for cytotoxicity or the primary mechanism of cytotoxicity. As a single agent in the treatment of ovarian cancer, altretamine demonstrates a response rate similar to other active agents in this disease (21-39 percent). The major utility of altretamine is in combination with other agents such as cyclophosphamide, doxorubicin, fluorouracil, melphalan, and cisplatin. However, few randomized trials have evaluated the contribution of altretamine in these multiagent combinations. Dose-limiting toxicities include gastrointestinal (nausea, vomiting, anorexia), hematologic, and neurotoxic (peripheral neurotoxicity). The therapeutic role of altretamine is limited because of a toxicity profile similar to that of cisplatin, one of the more active agents in ovarian cancer. Its use should be reserved for patients who are not candidates for more standard platinum-based regimens.

An early Phase II study of CTP-11, a new derivative of Camptothecin, in gynecologic cancers was carried out by a cooperative study group of 9 institutions. Forty-six patients were enrolled, and there were 14 cases of ovarian cancers, 7 of cervical cancer, 6 of uterine body cancers and 1 of endometrial stromal sarcoma which satisfied study criteria. The response rate in ovarian cancers was 21.4%, and in cervical cancers 42.9%, among an overall rate of 21.4%. Three out of 6 patients with objective response had undergone previous chemotherapies including cisplatin, suggesting that CPT-11 was effective for patients with no response or refractory to these therapies. Leukopenia was a major adverse reaction with an incidence of 60.0% (grade 2 or more). Gastrointestinal symptoms such as nausea vomiting, anorexia and diarrhea were frequently observed (grade 2 or more; 13.3-43.3%). These were generally tolerable except in a few cases. Besides these reactions, alopecia was also observed (33.3%), but severe adverse reactions such as nephropathy were not. These results suggested that CPT-11 was effective against ovarian cancer and cervical cancer. The recommended dose regimen for a late phase II study is considered to be 100 mg/m2 once weekly and 150 mg/m2 once every 2 weeks.

Forty-four patients with advanced, measurable, epithelial carcinoma of the ovary were treated with 97 courses of N-methylformamide (N-MF) at doses ranging from 600-800 mg/m2, intravenously, daily for 5 days every 28 days. Forty-one patients had prior surgery and had received one prior chemotherapy regimen. Only seven patients had received any prior radiation therapy. All patients were Gynecologic Oncology Group (GOG) performance status 0, 1, or 2. Three partial responses were seen. Hematologic adverse effects were extremely rare as predicted by early clinical trials. One major toxicity was a syndrome consisting of some combination of myalgias, arthralgias, pleuritic pain, abdominal pain, peripheral neuropathy, anorexia, lethargy, and declining performance status (pain-lethargy syndrome) that was reversible with discontinuation of the drug. This adverse effect was as common a reason as hepatic toxicity for discontinuation of N-MF. As reported in previous studies with this drug, hepatic toxicity was also common, usually reversible, and also a cause for discontinuation of the drug. The low level of clinical activity and the unpleasant adverse effects in this population of patients with previously treated ovarian cancer makes it unlikely that this drug will play any significant role in treatment of epithelial ovarian cancer.

The use of megestrol acetate in treatment of malignancy (endometrial carcinoma, ovarian cancer, prostate cancer, breast cancer, renal cell carcinoma, malignant melanoma), endometrial hyperplasia, benign prostatic hypertrophy, contraception, anorexia, cachexia and weight loss is reviewed, concluding with a toxicity profile. Megestrol acetate was introduced in 1971 for treatment of endometrial carcinoma. Megestrol acetate is probably effective in proportion to the number of cytoplasmic progesterone receptors, but it has not been tested in a Phase III trial. For ovarian cancer it has been reported to be effective in 1 trail at doses of 800 mg/day. Prostate cancer, although difficult to assess, responds to megestrol acetate at doses of 120 mg/day because of its suppression of gonadotropins, its inhibition of 5alpha-reductase and its binding to the dihydrotestosterone receptor. Megestrol acetate permits a lower dose of diethylstilbestrol, and thus lower toxicity. There is apparently a dose-response between megestrol acetate and breast cancer, along with a response dependent on the number and type of estrogen and progestin receptors. Responses are better in postmenopausal women, and additive with other agents such as tamoxifen and mitomycin C. The medium duration of effect is 6-8 months. It has no effect on renal cancer or malignant melanoma. Megestrol acetate can be considered as an effective medical alternative to surgery for endometrial hyperplasia or benign prostatic hypertrophy. As a contraceptive in inhibits sperm transport rather than ovulation, but also causes irregular bleeding. Megestrol acetate has few side effects, and has the advantage of stimulating appetite and weight gain, a benefit in cancer patients.

A phase I-II study of human recombinant interferon gamma (rIFN-gamma) was conducted in patients with various advanced cancer refractory to standard chemotherapies. In the phase I study, seven patients received 14 courses of escalating doses ranging from 2 X 10(6)U/m2 to 64 X 10(6)U/m2 by 1-hour intravenous infusion for 5 consecutive days. The toxicities were high fever with chills, anorexia, occasional nausea and vomiting, elevation of serum GOT, and dose-related leukopenia and neurotoxic symptoms such as heavy fatigue with somnolence or lethargy, both of which were reversible. The pharmacokinetics showed that the peak levels of serum rIFN-gamma activity were dose-related but decreased rapidly to below measurable levels within 6 hours after infusion in patients receiving less than 12 X 10(6)U/m2. Considering these data, the dosage of rIFN-gamma 6 X 10(6) U/m2 by daily intramuscular injection for more than 4 weeks was selected for the early phase II study. There was no partial response out of 11 evaluable patients but a stable condition was observed in 2 cases of renal cell carcinoma and one case each of breast cancer and ovarian cancer. All toxicities seen were similar to those observed in the phase I study, but no tachyphylaxis developed with continued dosage. The antitumor effect of rIFN-gamma remains to be evaluated in a further study employing higher doses.

Hexamethylmelamine (HMM) was selected for development as an antineoplastic agent because it demonstrated activity in a variety of preclinical tumor models. Its mechanism of action is unknown. It has been used in clinical trials since 1964. The clinical toxic effects have consisted of signs and symptoms involving the following systems: gastrointestinal (nausea, vomiting, anorexia), hematologic (leukopenia, mild anemia), and neurologic (critical depression, hallucinations, peripheral motor and sensory deficits). Antitumor activity against advanced ovarian cancer was demonstrated in phase I trials and the drug was quickly incorporated into trials which utilized drug combinations. The majority of these have consisted of phase II trials without an identified control population. As might be predicted, all of the HMM-containing combinations are active. However, the contribution of HMM to the antitumor activity of the combination remains conjectural. Thus, in spite of greater than 15 years of clinical trials with a drug that has single-agent activity, the questions regarding the role of HMM in the treatment of ovarian cancer remain unanswered.

Recombinant interferon alpha-2 (Sch 30500) was administered to 29 patients with advanced gynecological cancers (14 patients with cancer of the cervix, 8 with ovarian cancer, 4 with uterine sarcoma, 2 with endometrial cancer and 1 with unclassified cancer). No antitumor effects (CR and PR) were noted in 23 evaluable patients. Side effects observed were fever, tachycardia, diarrhea, chills, general fatigue, anorexia, nausea and vomiting. In some patients, leukopenia, decrease of hemoglobin and elevation of SGOT and SGPT were observed. No production of antibody for Sch 30500 was noted.
