Sixty women with breast cancer (mean age: 61 years; range 36-78 years) were treated with Epirubicin (4'epi-Doxorubicin), 60 mg m-2, as single drug therapy. The drug was administered as 2 hours' constant rate infusions. The pharmacokinetics of the drug during the first course of treatment was evaluated by measurements of the plasma concentration of Epirubicin at the end of the infusion period. There was a five-fold inter-individual variation of the dose-normalized maximum plasma concentration, which increased with increasing age of the patients. There was no correlation between this pharmacokinetic parameter and degree of obesity. An increase in maximum plasma concentration was associated with an increasing degree of alopecia (p = 0.025). Also the degree of nausea and vomiting showed a tendency to increase with increasing maximum plasma concentration (p = 0.07). Fifty four of the sixty patients entered in the present study were evaluable for clinical response. There was one CR (complete remission). Seventeen patients achieved PR (partial response), and twenty five patients had SD (stable disease). Eleven patients did not respond to treatment. The median maximum plasma concentrations were 322, 316, 336 and 288 ng ml-1 in patients with CR, PR, SD and PD, respectively. The results in the present study showed that 60 mg m-2 of Epirubicin given as a constant rate infusion over 2 hours is a useful alternative to more aggressive combination drug therapy for the treatment of breast cancer.

The simultaneous occurrence of breast cancer and pregnancy is rare. Little data are available about cytostatic treatment in patients with breast cancer during pregnancy. We report on a 31-year-old woman with a 28-week pregnancy and a T3 N+ Mx breast cancer treated with weekly doxorubicin chemotherapy. This was a well tolerated treatment without toxicity or complications for the mother. A partial response of the tumor was observed after 4 treatment courses. A normal baby was delivered. Doxorubicin and its metabolites were not detected in amniotic fluid collected through amniocentesis. Macroscopic and pathologic examinations of the placenta were normal. Although larger experiences are needed, weekly doxorubicin seems to yield satisfactory results without additional risks of fetal distress or malformations when given in women during the second and third trimester of pregnancy.

Doxorubicin (ADM) and epirubicin (epi-ADM) were tested at a dose of 150mg given intraarterially to 31 patients (ADM 14, epi-ADM 17) with advanced breast cancer. The clinical response rate was 78.6% in ADM (1 CR and 10 PR) and 76.5% in epi-ADM (1 CR and 12 PR). The histological response rate of 57.1% was also obtained in ADM and 56.3% in epi-ADM. No significant differences were evident between the two drugs. As for side effects, hair loss and gastrointestinal disorders were frequently documented low grade and less following administration of epi-ADM as compared to ADM. A more favorable prognosis seems possible with epi-ADM compared with ADM. Intra-arterial infusion chemotherapy with epi-ADM appears to be effective for the treatment of advanced breast cancer and is less toxic that ADM.

A case of metachronous lung metastasis treated by the combination therapy of Etoposide, Epiadriamycin and CDDP (modified EAP) is reported. A 47-year-old female who had undergone standard radical mastectomy for left. breast cancer was shown to have multiple metastases to the right. lung two years and seven months after surgery. The metastatic lesions disappeared after six series of modified EAP (VP 16 450 mg + ADR 40 mg + CDDP 100 mg/body) x 6 in seven months. Major side effects such as leukopenia and thrombocytopenia were not observed during the course. No recurrence had been noted for 14 months since the disappearance of the metastatic lesions. It is thus emphasized that the effect of EAP may be expected for the treatment of breast cancer.

Doxorubicin is an essential component of the treatment of aggressive lymphoma, childhood solid tumors, bone and soft tissue sarcomas, and breast cancer and additional indications are emerging. On the other hand, daunorubicin has occupied the central position of interest in the treatment of acute leukemia. Epirubicin has a spectrum very similar to doxorubicin but lesser toxicity. The ability to protect against cardiotoxicity with ICRF-187 further enhances clinical interest in exploiting modifications in doze intensity to therapeutic advantage. Idarubicin has at least equivalent activity to daunorubicin and doxorubicin in leukemia. New areas of research in relation to anthracycline antibiotics include introduction of new the analogs, insight into mechanisms of resistance, the reversal of multidrug resistance in vitro, the protection of cardiac toxicity, and the study of other important biochemical reactions relevant to cytotoxicity. Orally active anthracyclines such as idarubicin and compounds which lack cross-resistance with the parent drugs or have other mechanisms for cytotoxicity are being developed. It is likely that these modifications will lead to an expanding therapeutic spectrum for these already widely useful drugs.

Two hundred and fifty evaluable patients with breast cancer entered a protocol combining neoadjuvant and consolidation therapy by vinblastine (V), thiotepa (T), methotrexate (m) and 5-fluorouracil (f) (VTMF) with or without Adriamycin (A) (Doxorubicin; Adria Laboratories, Colombus, OH USA), and radiation therapy as exclusive locoregional treatment. Tamoxifen was given to 195 patients, 130 post menopausal and 65 pre-menopausal, and was omitted in 55 patients (31 postmenopausal and 24 pre-menopausal). There were 19 stage I, 86 IIa, 51 IIB, 36 IIIA and 58 IIIB. Primary chemotherapy induced tumor volume regression of more than 75% in 41% of the patients and complete clinical regression in 30% of the patients. The 5 years DFS rates were 100% for stage I, 82% for stage IIA, 61% for stage IIB, 46% for stage IIIA and 52% for stage IIIB patients. Among the 72 primary relapses there were 39 distant metastases, 6 locoregional and distant metastasis and 27 isolated locoregional metastases. The actuarial rate of locoregional recurrence is 13% for T2, 18% for T3, 19% for T4. At 5 years the rate of breast preservation was 94%. Cosmetic results are excellent or good for most patients. The 5 years overall survival (OS) were 95% for stage I, 94% for stage IA, 80% for stage IIB, 60% for stage IIIA and 58% for stage IIIB. In multivariate analysis tumor regression appears as an independent and significant factor. This parameter should be preserved in many patients with infiltrative breast cancer.

Between January 1977 and December 1989, 140 patients of Stage III breast cancer were treated in Sapporo Medical College. Sixty-six of these patients received intra-arterial infusion chemotherapy. The anticancer drugs were mainly given by two routes, infusion into the internal mammary artery and the subclavian artery. Continuous infusion of 5-FU and intermittent injections of ADR, MMC, 4'-epi-ADR or THP-ADR were jointly or individually made in each artery. The 5-and 10-year overall survival rates were: infusion group 49.2% and 49.2%, non-infusion group 64.0% and 45.0%, respectively. Intra-arterial infusion chemotherapy seems to be useful because non-infusion group contained mostly Stage IIIa and conversely the infusion group contained mostly Stage IIIb. A significant difference was seen between 5-FU infusion group and MMC.ADR group (p=0.026). MMC group, MMC + ADR combination group and 4'-epi-ADR group were marginally significantly different in terms of survival rates of the anticancer drugs of Stage IIIb.

The effects induced by the antiandrogen Cyproterone Acetate (CPA) on the proliferation of EVSA-T human breast cancer cells endowed with androgen receptors were studied. Kinetic analyses were carried out by two autoradiographic techniques measuring the percentage of cells in S-phase and the growth fraction (GF). The exposure of the cultures to CPA for 24 h caused a marked inhibition on S-phase cells without significantly affecting the CF. The accumulation of cells in G1-phase, confirmed by cytometric analysis, was rescued to the S compartment by replacing the culture medium 24 h after CPA administration. Exposure of EVSA-T to Doxorubicin or Methotrexate after CPA and medium change at the time of maximal proliferative recruitment, led to an enhancement of cytotoxicity as demonstrated by colony survival assay.

The aim of the present study is to confirm the antitumor activity of orally administered idarubicin (IDA) in patients with advanced breast cancer. Doxorubicin (ADRIA) was chosen as control treatment and the patients were randomized to receive either IDA or ADRIA according to a 2:1 ratio. Sixty-three patients, 77% of whom were pretreated with chemotherapy excluding anthracyclines, entered the study. The doses were: IDA 45 mg/m2 orally on 3 consecutive days every 28 days: ADRIA 75 (60) mg/m2 intravenously every 21 days. A complete + partial response (CR + PR) was observed in 11/37 (30%) evaluable cases treated with IDA and in 6/19 (32%) cases treated with ADRIA. If all the patients were included, the CR + PR remission rates were 27.5 and 27%, respectively. There were no significant differences as regards time to remission, duration of remission and survival. None of 10 cases who crossed over the treatments responded to the second therapy. The most frequent side effects of IDA were myelosuppression and nausea/vomiting. The only significant statistical difference between the two anthracyclines was the lower incidence of alopecia after IDA. Although there were 3 cases of cardiotoxicity after ADRIA, 2 of which severe, no case of clinical cardiotoxicity was observed after IDA. The present study confirms that orally administered IDA is an active agent in advanced breast cancer.

Nineteen evaluable patients with advanced breast cancer were treated with a combination of doxorubicin and etoposide. Patients had measurable disease, received only mild pretreatment and most had good general conditions at start of therapy. Strict criteria for dose adjustments according to nadir counts were applied. A 42% response rate was obtained. Toxicity was mild and treatment well-tolerated. Doxorubicin-etoposide is an active regimen for patients with breast cancer and warrants further testing in a larger patient population with less stringent criteria for evaluation and treatment monitoring.
