Of the new anthracycline derivatives, epirubicin is the antibiotic whose antitumor activity is comparable to that of doxorubicin while its cardiotoxicity is reduced by half. We therefore incorporated into our continuing study on anthracycline antitumor effects and toxicity a group of 22 evaluable patients, mean age 52 years, with advanced breast cancer, all of whom had previously undergone chemotherapy, radiotherapy and/or hormonal therapy. Epirubicin was administered at a dose of 120 mg/M2 every 3 weeks, for a maximum of 10 such cycles. The left ventricular ejection fraction (LVEF), determined by radionuclide ventriculography, was measured periodically in all patients. We observed 2 complete responses and 13 partial responses (CP + PR = 69%) of 61 weeks' mean duration; in 3 cases lesions remained stationary while the disease progressed in 4 patients. No patients died of acute toxicity. The main side effects were severe alopecia in 82% of the subjects and moderate degrees of nausea without vomiting in 41%. After 6 treatment cycles, 4 patients showed mild cardiotoxicity and at an epirubicin cumulative dose of 1,200 mg/M2 2 patients developed congestive heart failure (CHF). Hematological toxicity was in no case so severe as to require a reduction in the dose but only a postponement of treatment by 3 to 5 days in 9% of cycles. Without increasing hematological or cardiac toxicity, epirubicin, at a dose of 120 mg/M2, has shown itself to be a highly effective agent against advanced breast cancer.

Epirubicin is a new anthracycline with a potentially more favorable toxicity profile than the parent compound, doxorubicin. Accordingly, the feasibility and toxicity of 6 courses of adjuvant chemotherapy with cyclophosphamide (C), epirubicin (E), and 5-fluorouracil (F) were assessed in 10 patients with Stage 2 (node positive) breast cancer. Doses of C and F were 600 mg/m2 and E was 75 mg/m2. Moderate granulocytopenia (median count = 610/mm3) occurred on day 14 of the first 21 day treatment course and was the main toxicity encountered with treatment, although there were no episodes of granulocytopenic fever. Grade 3 or 4 vomiting occurred in 40% and significant alopecia in 30% of patients. Four patients experienced transient asymptomatic decreases in calculated radionuclide cardiac ejection fraction of greater than or equal to 10% but no signs or symptoms of cardiac failure were observed. If epirubicin proves to be less cardiotoxic than doxorubicin, this combination would merit further evaluation as potential adjuvant therapy for early breast cancer.

From February 1983 to January 1985, 497 patients with advanced breast cancer were randomly allocated to receive either epirubicin or doxorubicin in the following combination chemotherapy regimen: fluorouracil (5-FU) 500 mg/m2 intravenous (IV) on days 1 and 8; epirubicin or doxorubicin 50 mg/m2 IV on day 1; cyclophosphamide 500 mg/m2 IV on day 1 (FEC or FAC). Cycles were repeated every 21 days until progression or to cumulative doses of 700 mg/m2 for epirubicin and 550 mg/m2 for doxorubicin. Dose reductions were applied according to the standard criteria. Activity was evaluated in 443 patients (222 in the FEC arm and 221 in the FAC arm). The two experimental groups were comparable in age, performance status, menopausal status, histology, previous treatments, and site of the disease. The overall response rate (complete response and partial response [CR + PR]) was not significantly different: 53.6% for FEC and 56.5% for FAC. The median time to progression was 273 days for FEC and 314 days for FAC; the median survival time was 591 and 613 days, respectively. Leukopenia, anemia, nausea, and vomiting were significantly lower in patients treated with FEC. As for cardiotoxicity, four cases of congestive heart failure (CHF) were recorded among patients treated with FAC while only one was observed in the FEC group. These results indicate that epirubicin in a combination chemotherapy regimen is as active as doxorubicin and is significantly less toxic.

Phase II study of 5'-DFUR was conducted in 195 patients with malignant tumors by the Osaka Chemotherapy Cooperative Study Group. Five CR and 20 PR cases were obtained out 133 evaluable cases and the total response rate was 18.8% (15.8% in gastric, 38.1% in breast) One PR was observed for each of head & neck and esophageal cancer. It was noteworthy that four CR were observed in breast cancer. Adverse reaction was observed in 61 out of 151 cases (40.4%), and major side effects were digestive symptoms such as diarrhea (22.5%), nausea-vomiting (11.9%) and anorexia (10.6%). These results suggest that 5'-DFUR can be useful for the treatment of malignant tumors.

5'-DFUR was administered orally to advanced or recurrent cancer patients at a daily dosage of 600-1200 mg divided into 3 or 4 times a day. Out of 13 evaluable cases 2PR, 2MR, 4NC and 5PD were observed, response rate was 15.4%. PR were obtained in one gastric cancer case and one breast cancer case. Side effects were observed in 6 cases out of 14 cases (42.9%) and major adverse reaction was gastro-intestinal toxicities such as anorexia, nausea-vomiting and diarrhea. Two leukocytopenia and one erythrocytopenia were observed. This study indicated that 5'-DFUR would be useful as a new anticancer agent.

Recently 5'-DFUR (5'-deoxy-5-fluorouridine) was developed as a new anticancer drug in Japan. The compound was active against various murine tumors by oral administration and the toxicity was almost comparable to the other prodrugs of 5-fluorouracil (5-FU). 5'-DFUR is converted to 5-FU in vivo by pyrimidine nucleoside phosphorylase which was found to exist relatively much in tumor tissues compared to normal ones except intestinal tract. In the phase I study, the dose-limiting toxicities were gastro-intestinal (GI) ones such as nausea, vomiting, anorexia etc., and the MTD was 2,100 mg/body/day (oral administration). In the multi-institutional phase II studies, clinical activity of 5'-DFUR was found in head and neck, thyroidal, esophageal, gastric, colo-rectal, gall-bladder and breast cancers at daily doses of 800-1,200 mg/body. The main side effects were consisted of GI-toxicities in which diarrhea appeared most frequently (26.3%). This diarrhea, however, disappeared rapidly by decreasing the dosage or termination of treatment. In the comparative clinical studies of 5'-DFUR with tegafur against advanced breast cancer cases, 5'-DFUR was found superior to tegafur in the clinical responses. From these results, 5'-DFUR was judged as an useful new anticancer drug.

The present paper concerns two multicenter studies on adjuvant therapy with medroxyprogesterone acetate (MAP) for operable N+ breast cancer. The patients entered the study between April 1979 and March 1986. One hundred and fifty-one premenopausal patients were randomly assigned to receive either polychemotherapy (CMF) or CMF + MAP. One hundred and thirty-eight postmenopausal patients were randomized to receive either MAP h.d. or no treatment. CMF was administered according the following schedule: cyclophosphamide mg 100/ms p.o. 1-4 days; methotrexate mg 40/ms i.v. and fluorouracil mg 600/ms i.v. 1st and 8th days. The cycle was repeated six times every 28 days. MAP was administered at 1000 mg X 2/daily p.o. for 30 days and afterwards 500 mg X 2/daily for 5 months. In the premenopausal study after a median follow-up of 36 months no difference was observed in the incidence of recurrence, site of recurrence, actuarial 5-year disease-free survival (DFS) or overall survival (OS). In the postmenopausal study a statistically significant lower number of recurrences was observed in MAP-treatment patients after a median follow-up of 37 months. The effect of MAP was limited to patients with less than or equal to 3 metastatic axillary lymph nodes. In addition, there are suggestions that only patients with ER+ tumors draw some advantage from the treatment. On the other hand, no difference exists in the OS. The treatments were substantially well tolerated. The MAP + CMF regimen induces lower vomiting compared to the CMF alone. The most frequent MAP side-effects were vaginal spotting (16%) and tremors (12%). We conclude that MAP h.d., like tamoxifen and aminoglutethimide, can improve the DFS of operable N+ breast cancer in postmenopausal patients.

Epirubicin (4'-epidoxorubicin) is an antineoplastic agent derived from doxorubicin. The compounds differ in the configuration of the hydroxyl group at the 4' position. Epirubicin, like doxorubicin, exerts its antitumor effects by interference with the synthesis and function of DNA and is most active during the S phase of the cell cycle. Epirubicin is administered by intravenous (IV) injection. It is metabolized by the liver and primarily eliminated in the bile. About 10% of the drug is eliminated in the urine. Dosage adjustments are recommended for patients with liver metastases or elevated liver function tests. The elimination half-life of epirubicin is 30 to 40 hours. Clinical studies indicate activity in breast cancer, non-Hodgkin's lymphomas, ovarian cancer, soft-tissue sarcomas, and pancreatic cancer. There is also evidence of activity against gastric cancer, small-cell lung cancer, and acute leukemia. Epirubicin has limited activity as a single agent against head and neck tumors or non-small-cell lung cancer, but may be beneficial in combination with other agents. The overall activity of epirubicin appears to be comparable with that of doxorubicin. However, more studies are needed to define its role in combination chemotherapeutic regimens. The acute dose-limiting toxicity of epirubicin is myelosuppression. Nausea, vomiting, and alopecia are also common. Epirubicin may cause transient cardiac arrhythmias and alterations of the electrocardiogram. Chronic therapy is limited, but available data indicate that epirubicin can be administered in higher cumulative doses than doxorubicin before cardiotoxicity limits further therapy.

The antiemetic effectiveness of haloperidol plus dexamethasone was compared with that of prochlorperazine plus dexamethasone in a prospective study of patients receiving chemotherapy for breast cancer. Chemotherapy consisted of cyclophosphamide, doxorubicin or methotrexate, and fluorouracil in all patients. Patients who received the doxorubicin-containing combination experience significantly more nausea and vomiting than those who received the chemotherapy combination containing methotrexate. There was no significant difference between the two antiemetic regimens in the overall incidence of post-chemotherapy nausea and vomiting, but patients who received haloperidol and dexamethasone did have a lower incidence of severe vomiting. Neither regimen is highly effective, especially for the combination containing doxorubicin, and cannot be recommended as standard antiemetic therapy for this population of patients.

Twenty-five women with advanced breast cancer were treated in a phase II trial of iproplatin 275 mg/m2 administered intravenously every 4 weeks. All patients had measurable or evaluable indicator lesions, and had undergone treatment with no more than one previous chemotherapy regimen, including adjuvant chemotherapy. Two of the twenty-four evaluable patients (8%) experienced major therapeutic responses. One patient had a complete regression of pulmonary nodules lasting 18+ months; another had a partial regression of metastatic disease in the liver (4 months). The inevaluable patient was ineligible for the study because of previous radiation to the indicator lesions on her chest wall; nonetheless, she experienced a 10 month partial regression of those nodules. Myelosuppression was generally dose limiting; thrombocytopenia was more profound, but leukopenia was more prolonged. Nausea, vomiting, diarrhea, and general malaise were prominent toxicities, and led to discontinuation of therapy in 4 patients. Iproplatin has limited activity in previously treated women with advanced breast cancer.
