A new antitumor agent, UFT, was administered to one patient with endometrial cancer and one with ovarian cancer. Case 1:53 year-old female with advanced endometrial cancer with an invasion to the bladder. Histological diagnosis was endometrial carcinoma. UFT of 600 mg per day was administered orally daily for 28 days as one course. Palpable inguinal lymph nodes and suprapubic uterus mass were disappeared by one course of UFT. Case 2:50 year-old female with recurrent ovarian cancer invading to the rectum and uterus with a histological diagnosis of papillary tubular adenocarcinoma. One course of UFT produced 64% decrease in the pelvic tumor size, and additional one course 74% decrease. No marked side effects except stomatitis in case 1 were noticed during UFT administration. Although, unfortunately, these two patients died of ileus due to cancer, marked antitumor effects of UFT on endometrial cancer and ovarian cancer were elucidated.

Twenty-two patients with recurrent ovarian cancer were entered into a Phase II trial of edatrexate at a dose of 80 mg/m2 i.v. weekly for five consecutive weeks. One patient received an inadequate trial, and six did not complete one cycle due to adverse effects. There were 21 patients evaluable for toxicity and 15 for response. There were no objective responses, 10/15 (67%) had stable disease, 5/15 (33%) increasing disease. Toxicity was predominantly stomatitis and hematologic. Two patients developed skin rashes, and one experienced pulmonary toxicity felt to be related to the drug. Edatrexate administered in this dose and schedule has no demonstrated activity, but moderately severe toxicity in patients with previously treated advanced ovarian cancer.

In this Phase I study, the maximally tolerated doses (MTDs) of i.p. iododeoxyuridine (IdUrd) alone and in combination with i.v. calcium leucovorin (LV) were determined. The pharmacokinetics and pharmacological advantage of IdUrd were evaluated, and flow cytometric analysis allowed examination of the extent of incorporation of IdUrd into tumor cells with and without the addition of i.v. LV. Thirty-nine patients with advanced neoplasms primarily confined to the peritoneal space were enrolled in a dose-escalation trial using 4-h dwells of IdUrd administered i.p. daily for 4 days with and without an i.v. infusion of LV 500 mg/m2/day for 4.5 days. Twenty-three patients received single-agent therapy, and 13 patients received i.p. IdUrd in combination with i.v. LV. The MTD of single-agent IdUrd administered on this schedule was 4125 mg/m2/day for 4 days; and that of the IdUrd in combination was 3438 mg/m2/day. Dose-limiting toxicities were myelosuppression and stomatitis. During the period of the dwell, the peritoneal AUC (area under the curve) of IdUrd exceeded the plasma AUC of IdUrd by one or two orders of magnitude in all patients at all doses tested; there was a possible effect of LV on peritoneal AUC. The geometric mean pharmacological advantage (AUCperitoneal/ AUCplasma) was 181 at 625 mg/m2/day and 90 at 4538 mg/m2/day. Flow cytometric analysis suggests saturation of IdUrd measured in DNA at the 2500-3125 mg/m2 dose level, without an increase after the addition of LV. Twelve patients received 4-12 courses of therapy. One patient with recurrent ovarian cancer who received 16 courses of therapy experienced complete resolution of her ascites, near normalization of CA-125 levels, and improved quality of life; two patients with high-risk tumors receiving "adjuvant" therapy are disease-free at 3 and 6 years after treatment; other patients experienced transient clearing of ascites. The recommended Phase II dose of i.p. IdUrd using a 4-h dwell daily for 4 days is 3750 mg/m2/day alone or 3125 mg/m2/day in combination with continuous i.v. LV at 500 mg/m2/day for 4.5 days. Although flow cytometric data suggest that DNA incorporation of IdUrd is not affected by the addition of LV, the cytotoxicity of the combination regimen may be increased due to LV-enhanced, IdUrd-related inhibition of thymidylate synthase. For this reason, we recommend that efficacy studies of the combination continue in parallel with studies of IdUrd alone.
