Fifty-six evaluable patients with advanced ovarian carcinoma (FIGO III or IV), without prior cytotoxic chemotherapy, were studied to assess the activity of single-agent moderate-dose cyclophosphamide, 40 mg/kg to a maximum dose of 3000 mg, given intravenously as a bolus injection every 3 weeks. All patients were treated as outpatients. Moderate-dose cyclophosphamide resulted in 36 (64%) objective responses (19 CR, 17 PR). Nausea and severe vomiting occurred in all patients, but no patient needed hospitalization for this complication. Other side-effects observed were alopecia (100%), leukocytes less than or equal to 2500/microliters (18%), chemical cystitis (11%) and sepsis (4%). The median duration of response was 11 months, and the estimated median survival by the life-table method for responders was 16 months and for non-responders 4 months (P less than 0.001). Clinical trials previously performed by our group comparing cyclophosphamide alone, either vs cis-platinum, adriamycin and hexamethylmelamine or vs Hexa-CAF, showed a better remission rate with the use of moderate-dose cyclophosphamide alone. Therefore we suggest further investigation of this agent in a moderate dose in disseminated ovarian carcinoma.

Rosenberg et al discovered in the coordination complexes of platinum a new, novel type of potential antitumor agent. Cisplatin [cis-dichlorodiammine platinum (II)4 proved active against a variety of rodent tumors and acted synergistically when combined with other chemotherapeutic agents. Initial clinical tests by Hill et al in 1971, showed cisplatin to be active against malignant lymphoma, Hodgkin's disease, and certain other malignancies. Significant nephrotoxicity, nausea, and vomiting were noted. Since then, cisplatin has been tested alone and in combination chemotherapy and has proven an efficacious anticancer agent in squamous cell carcinoma of head and neck, ovarian carcinoma, disseminated testicular cancer, and others. Its therapeutic value was acknowledged when approved in 1978 by the U.S. FDA for treatment of the latter cancer. The current clinical literature indicates clearly that the full potential of this drug has not yet been realized. Hydration and diuresis have served to mitigate much of the nephrotoxicity, while significant strides toward amelioration of the nausea and vomiting have also been achieved. Literally, thousands of chemically-related congeners have been synthesized, and many have shown marked potency against rodent tumors. Very few, however, have been evaluated clinically, vis-a-vis malonato trans(-)-1,2-diaminocyclohexane platinum(II); this appears a most promising and fertile area of future investigation.

cis-Diammine-1,1-cyclobutane dicarboxylate platinum II (CBDCA, JM8), an analogue of cisplatin showing reduced toxicity in preclinical studies, was evaluated in 60 patients. Doses were given initially every 3 weeks and escalated from 20 to 520 mg/m2. Following this, doses were given every 4 weeks and escalated from 300 to 500 mg/m2. The dose-limiting toxicity, thrombocytopoenia, occurred in four-fifths of patients treated at 520 mg/m2, with the nadir occurring 3 weeks after treatment. Leucopoenia and anaemia also occurred but were less severe. Vomiting occurred in all patients receiving over 120 mg/m2 but seldom persisted beyond 24 h. Serial measurements of 51Cr-EDTA clearances, urinary N-acetylglucosaminidase, urinary leucine aminopeptidase, and beta 2-microglobulin did not reveal significant evidence of nephrotoxicity. Detriment to the audiogram has not been seen in the first 13 patients studied. Pharmacological studies showed that most of the dose of platinum was excreted in the urine, and that impairment of renal function may be associated with drug retention and an increased risk of myelosuppression. The previous therapy and age of the patient also affected the tolerance of the drug. Clinical responses were seen in patients with ovarian carcinoma receiving greater than 120 mg/m2. A further dose escalation was performed on a 4-week schedule in patients under 65 with good renal function. The maximum dose it was possible to administer repeatedly without incurring myelosuppression was in the range 400-500 mg/m2. JM8 is not significantly nephrotoxic and is less emetic than cisplatin. It has antitumour activity in man and deserves wider evaluation, along with the other analogues under study in various centres, as an alternative to cisplatin.

Corynebacterium parvum has been administered i.p. to 14 patients with advanced ovarian cancer. Two patients had responded completely to cytoreductive surgery and combination chemotherapy prior to immunotherapy, and one patient with residual disease had received only a single course of C. parvum due to i.p. catheter malfunction. Among the 11 patients with residual disease evaluable for response, from three to eight i.p. treatments with C. parvum produced surgically confirmed tumor regression in five patients (45%) with three partial responses and two complete responses of 5 and 12 months duration. All responders had (a) multiple tumor nodules less than 0.5 cm at the initiation of immunotherapy, and (b) severe abdominal pain and fever after C. parvum injection. Overall, 58 courses of immunotherapy were associated with abdominal pain (91%), fever (67%), nausea (52%), vomiting (31%), and hypotension that responded promptly to i.v. infusion of fluids (10%). Use of i.p. cathethers was associated with two episodes each of infection and intraabdominal bleeding. Administration of C. parvum i.p. has augmented the ability of human peritoneal cells to lyse human ovarian carcinoma cell lines in the presence of specific rabbit heteroantiserum. C. parvum administered i.p. has inhibited the growth of human ovarian carcinoma and may prove useful for modulating the activity of human effectors for antibody-dependent cell-mediated cytotoxicity.

THP-ADM is a new antitumor antibiotic which belongs to the anthracycline group. This agent was administered to 42 histology proven various malignant disease patients with a schedule of 60-80 mg per body (40-55 mg per m2) iv bolus, every three weeks. THP-ADM administration revealed mild upper GI toxicity (vomiting 19%, stomatitis 21%) and leukopenia (less than 2,000 per mm3) in 80% and thrombocytopenia (less than 60,000 per mm3) in 38% with good rebound. There was no signs or symptoms of cardiac failure including the patient who had received 740 mg per body (500 mg per m2). Definite response (CR, PR) was observed in ovarian carcinoma 4/11, cervix carcinoma 2/7, breast carcinoma 1/6, malignant lymphoma 5/5 and mesothelioma 1/2. Furthermore, some response (MR) was observed in lung metastasis from endometrial carcinoma 2/4, and stomach carcinoma 1/3. The above indicated usefulness of this agent and further study should be continued, especially a controlled study with adriamycin.

Acivicin [(alpha S,5S)-alpha-amino-3-chloro-4,5-dihydro-5-isoxazoleacetic acid; AT-125; NSC-163501] is a fermentation product of Streptomyces sviceus which is active in a variety of mouse tumor models including the L1210 and P388 leukemias, the M5076 ovarian carcinoma, and the MX-1 human breast tumor xenograft. Antitumor activity is probably mediated through the inhibition of enzymes catalyzing amido transfer from L-glutamine, especially CTP synthetase and XMP aminase. In mice, acivicin is absorbed systemically via the p.o., I.P., and S.C. routes and is predominantly excreted in the urine in unchanged form. Although a wide variety of toxicities, including myelosuppression, were noted in dogs and monkeys, vomiting, diarrhea, and pathologic lesions of the GI tract predominated in both species. A marked cumulative toxicity was noted in dogs with 16 mg/m2/day being the lethal dose on the daily x 5 schedule compared to 1000 mg/m2 on the single-dose schedule. An interesting phenomenon was noted in mice wherein older male mice were more resistant to the toxic effects of the drug than female or younger male mice. This sex and age difference in susceptibility to acivicin toxicity was shown to be correlated with differences in pharmacokinetics; older male mice cleared acivicin at approximately twice the rate of females or younger males. No sex differences in toxicity were noted in dogs or monkeys. Because of its activity in mouse tumor systems and acceptable preclinical toxicology patterns, the drug is being introduced into clinical phase I studies under the sponsorship of the National Cancer Institute.

Platinum derivatives are known as the most effective cytostatic agents in ovarian carcinoma. The steep dose-response curves described by Hryniuk and Levin [5] make them the ideal substances for dose escalation. We treated patients with advanced ovarian carcinoma with dose intensified carboplatinmonotherapy six times at AUC 5 (= +/- 400 mg/m2 in patients with normal renal function). Dose intensification was not done by increasing single doses, but by shortening the intervals between therapies (23, 21, 17, 14 days). In order to prevent leucopenia G-CSF was administered at a dose of 5 micrograms/kg s.c. Besides mild emesis no extramedullary toxicity especially no alopezia was documented. Up to an interval of 17 days therapy was safe; no thrombocytopenia < 49,000 x 10(6)/L and no leucopenia < 1000 x 10(6) was observed. With the intention to arrive at a 14-day interval and to attain further dose escalation we will treat future patients with a slightly reduced dose of carboplatin (AUC 4) in combination with escalating doses of cis-platinum, which is known for its low myelotoxicity.

Primary adenocarcinoma of the jejunum which accounts for only approximately 3% of all gastrointestinal tract malignancies, is distinctly unusual. Ovarian metastasis from a jejunal cancer is extremely rare. It has significant therapeutic and prognostic implications to differentiate primary ovarian carcinoma from metastatic disease to the ovary. A 49-year-old Japanese woman presented with intermittent nausea, vomiting, and palpable abdominal mass. Pelvic examination and imaging studies revealed a huge ovarian tumor, suspicious for malignancy. Upper GI series and barium enema were unremarkable. Exploratory laparotomy was done for presumed primary ovarian malignancy. Mucinous adenocarcinoma of the right ovary, measuring 25 x 18 x 12 cm, without other intraabdominal dissemination was found. Exploration of the upper abdomen revealed an annular constriction of the jejunum 30 cm distal to the ligament of Treitz. Partial jejunectomy with end-to-end anastomosis was done. Metastatic ovarian cancer from the primary jejunal adenocarcinoma was confirmed microscopically. Although small bowel malignancy is uncommon, small bowel follow-through examination or enteroclysis may be indicated in patients with positive stool for occult blood who have no abnormality in the upper gastrointestinal series and barium enema. In addition to the imaging studies, thorough exploration of the entire abdominal cavity is necessary at ceiliotomy in patients with ovarian malignancy to distinguish primary ovarian cancer from metastatic disease to the ovary.

In view of the single agent activity of both cisplatin and carboplatin in epithelial ovarian cancer, and their different toxicity profiles, we carried out a phase II study of low dose cisplatin (50 mg/m2) in combination with moderate dose carboplatin (300 mg/m2) in patients with advanced ovarian cancer. Fourteen patients, all of whom had bulky disease and over half of whom had Stage IV disease, were eligible for assessment of response and toxicity. An overall response rate of 71% was demonstrated (57% complete response, 14% partial response), which is at least equivalent to other regimens used in first line treatment of ovarian cancer. Toxicities encountered were nausea/vomiting and myelosuppression, however no serious renal neuro or ototoxicity was observed and the regimen does not cause significant alopecia. This combination may be a practical alternative to regimens which use high dose cisplatin to achieve similar efficacy.

We carried out a phase II study on single oral administration of UFT in 17 patients with ovarian carcinoma. Two PR cases were observed out of 13 evaluable cases for a response rate was 15.4%. Side-effects, appearing in 10 of the cases (58.8%) were mainly anorexia (17.6%), stomatitis (17.8%), nausea/vomiting (11.8%), leukopenia (11.8%) and thrombocytopenia (11.8%), but they were not serious. UFT proved useful in the treatment of patients with ovarian carcinoma.
