Twenty-eight and 24 patients with advanced breast cancer were treated with Aminoglutethimide (AG) or AG + Tamoxifen (AG + TAM) from June 1984 to June 1989, respectively. Evaluated cases were 25 and 21 treated with AG or AG+TAM, respectively. Objective response was seen in 5/25 (20.0%) for AG treatment with 9, 13, 16, 20 and 31 months remission and 4/21 (19.1%) for AG + TAM treatment with 6, 7, 12 and 26 months remission. Response rate according to dominant site of metastases were 1/10 in soft tissue, 2/7 in bone, 2/7 in lung and pleura treated with AG, 1/9 in soft tissue, and 3/5 in lung treated with AG + TAM treatment. Two of the 5 responding patients in AG treatment group had prior tamoxifen treatment and 3 out of 4 responding patients in AG + TAM treatment group had prior chemoendocrine therapy with tamoxifen and FAC chemotherapy. Main toxic side effects were lethargy and/or rash, and drug discontinuation was required in 3 cases of AG treatment group and 2 cases of AG + TAM treatment group. Serial determination of serum hormone levels during AG or AG + TAM treatment revealed a decrease in estrone and an increase in androstenedione in many cases of both treatment groups. This data suggested that AG treatment may be favorable for endocrine treatment for advanced breast cancer patients, but the response to AG was not augmented by adding TAM.

From September 1983 to March 1988, 57 patients with locally-advanced breast cancer were treated at the Istituto Nazionale per la Ricerca sul Cancro in Genoa, Italy. All patients received 3 cycles of induction chemotherapy with estrogenic recruitment before surgery (diethylstilbesterol-DES-FAC) and 6 additional cycles of chemotherapy (3 DES FAC alternating with 3 DES CMF) after surgery. Stage III A (15) patients reached 86% local relapse-free survival (LRFS), 68% disease-free survival (DFS), and 85% overall survival (OS). Stage III B (42) patients had 82% LRFS, 59% DFS, and 33% OS at 5 years. The first site of relapse was locoregional in 35% of the patients: 19% chest wall recurrence, 3.5% chest wall and lymph nodes, and 7% regional nodes; 5% of the cases presented synchronous local and systemic recurrence; distant metastases represented 21% of the initial relapse rate. This therapy appears to improve the prognosis of III A patients more than that of III B patients. Unsatisfactory results were obtained in inflammatory cancer, with 54% of local recurrences. The present study indicates that radiotherapy is necessary to improve local control and to increase DFS in inflammatory breast cancer. Moreover, the use of radiation therapy also improves the results in III A and III B patients.

Phase II studies of p.o. Idarubicin administration, a new daunorubicin analogue (4-demethoxy-daunorubicin), have shown antitumor activity in 23%-31% of previously treated metastatic breast cancer patients, while in untreated patients a response rate of 41% was observed. Our Phase II study has shown an overall response of 23% [1 complete response (CR), 9 partial response (PR), 10/43] with a daily dose of 15 mg/m2 p.o. on days 1,2,3. On the basis of these results we have recently included Idarubicin in combination chemotherapy of breast cancer, substituting Adriamycin by Idarubicin in an FAC schedule. Of 50 consecutive metastatic breast cancer patients who entered the study, 42 patients who received greater than 2 cycles were evaluable. There were 22 premenopausal and 20 postmenopausal patients (mean = 51 years). In 25 patients a performance status of 0-2 (ECOG) was registered and in 17 patients it was 3. Previous radiation had been administered in 34, hormonal therapy in 18, and adjuvant chemotherapy (CMF 5, CMFVP 3) in 8 patients; 22 patients had predominant metastatic sites in soft tissues, 18 in visceral organs, and 2 in the bones. The FIC schedule was administered as follows: 5-fluorouracil 500 mg/m2 i.v. days 1 and 8, Idarubicin 15 mg/m2 p.o. days 1, 2 and 3, and cyclophosphamide 500 mg/m2 i.v. day 1. An objective response was observed in 23 (5 CR, 18 PR) out of 42 patients (53%, CR 12%). Soft tissue metastases responded in 55% (12/22), visceral organs in 61% (11/18), and no response was observed in bone lesions (0/2). The median remission duration was 8 months (3-16+). Toxicity was mild, expressed mainly in the form of nausea/vomiting, grade I and II in 64% of the patients. Alopecia was very mild (grade I and II in 23% of the patients). Leukopenia grade I-II was observed in 21% of the patients. In 4 patients reversible ECG changes occurred. Left ventricular ejection fraction did not show any pathological changes. The Idarubicin-containing combination chemotherapy we have used has the following characteristics: easier administration (p.o. anthracycline, no risk of tissue extravasation), lower toxicity (cardiotoxicity, alopecia, and myelosuppression in particular), and a notable antitumor activity.

One hundred thirty-three consecutive, previously untreated patients who had metastatic breast cancer were treated with a combination of 5-fluorouracil, doxorubicin (Adriamycin), and cyclophosphamide (FAC). They were randomly assigned to receive nonspecific immunotherapy with a heptavalent pseudomonas vaccine. Sixty-five patients were treated with pseudomonas vaccine, whereas 68 did not receive immunotherapy. In addition, all patients with estrogen receptor-positive tumors or tumors with an estrogen receptor status were also treated with tamoxifen. To allow clinical assessment of hormone sensitivity in vivo, tamoxifen was started 6 weeks before chemotherapy except in patients who had life-threatening disease. After the initial 6 weeks of tamoxifen, 3% of patients had achieved a complete remission, 9% a partial remission, while 16% achieved a minor response. The maximum response after tamoxifen and chemotherapy included complete remissions in 20% of patients and partial remissions in 61% of patients for an overall remission rate of 81%. The median response duration was 15 months, and the median survival time, 27 months. There were no differences in remission rate, remission duration, or survival time between the groups treated with or without pseudomonas vaccine. Eleven patients with limited metastatic disease received radiotherapy consolidation to initially involved sites. In these patients the median time from radiotherapy to progression of disease was 33 months, and the median survival time was 46 months. We conclude that nonspecific immunotherapy with pseudomonas vaccine failed to increase remission rate or survival time. Furthermore, the addition of tamoxifen to FAC chemotherapy did not improve the remission rate or duration compared to a recent, historical control group of patients treated with only FAC chemotherapy.

Nine 44- to 67-year-old patients with inflammatory breast carcinoma were treated over 2 weeks with intratumoral injections of Propionibacterium granulosum KP-45 (KP). This period of immunotherapy was succeeded by four courses of chemoimmunotherapy (FAC: 5-fluorouracil, adriamycin, and cyclophosphamide + intratumoral KP). Inflammatory symptoms disappeared in three patients during immunotherapy and in the remaining six patients during the following chemoimmunotherapy. Finally, 3 to 4 months after starting the therapy, all nine patients were free from inflammatory symptoms and it became possible to perform radical (seven cases) or simple (two cases) surgery. Thereafter routine therapy (radiotherapy, fractionated dose of 5500 R, followed by 10 FAC courses + single injections of KP for each FAC course) was used. After 19 to 32 months observation time all patients are still in complete remission with no local recurrences. Only one patient showed distant metastases during the observation period.

The case of a 36 year old patient in whom breast cancer was diagnosed in February 1983 is reported. At the time of the diagnosis bone metastases, were already present. Therapy was started on the basis of a FAC-regimen (Ftorofur-, Adriamycin-Cyclophosphamide), where after the patient developed clinical and laboratory signs of hepatic lesion. At the time of the first FAC-course the suspicion of viral hepatitis of cholestatic type was raised; HBsAg was consistently negative. In the 3rd week after completion of the second FAC-course clinical signs of cholestatic hepatitis with high fever and leucopenia of increasing severity were suggestive of drug-induced hepatitis. Cyclophosphamide was incriminated, therefore, this component was omitted from the subsequent FAC-course. Nevertheless, the clinical manifestations reappeared in a more pronounced form. This time, too steroids were administered, with beneficial effect. In view of the complaints pointed to bone-metastases further cytostatic treatment, Vepesid monotherapy was started, but after the first course the patient developed hepatitis and died. Necropsy revealed, in addition to extensive bone-metastases, microscopic signs of drug-induced hepatitis. The types of liver damage caused by the cytostatic agents used in this study are reviewed. No hepatitis has been reported in connection with these drugs (Adriamycin + Ftorofur or Vepesid) thus far. The diagnostic criteria of drug-induced hepatitis are outlined. It is pointed out that with the eves more extensive use of cytostatic therapy a growing incidence of this complication should be taken into account.

A clinical phase II study was performed to evaluate the therapeutic efficacy of simultaneously administered aminoglutethimide and polychemotherapy in 31 patients with predominant bone metastases of breast cancer. The majority of patients was postmenopausal and pretreated with hormones and (or) chemotherapy. In 28 evaluable patients an overall objective response rate of 61% was achieved. Patients who received aminoglutethimide and polychemotherapy containing anthracyclines as FAC- or AV-regimen showed the highest objective response rate (67%). Thus, simultaneous combination of aminoglutethimide and polychemotherapy containing anthracycline derivatives is the most effective therapeutic regimen for those patients who were either pretreated or have progressive bone metastases with confinement to bed or have concomitant visceral metastases.

Fifty-two patients with locally advanced primary breast cancer (T3, T4, N2, N3) but no evidence of distant metastases were treated with three cycles of combination chemotherapy. The regimen consisted of 5-fluorouracil, Adriamycin, cyclophosphamide, and Bacillus Calmette-Guerin (FAC-BCG), followed by local therapy (simple mastectomy and/or radiotherapy to the breast/chest wall and the regional lymphatic system) and adjuvant chemotherapy for two full years. The results were compared with those in an historical control group of 52 patients matched for initial stage of disease who were treated by a simple mastectomy and postoperative radiotherapy only. Forty-nine (94%) of 52 FAC-treated patients and 48 (92%) of the control patients became free of clinically detectable disease. At the median follow-up time of 56 months, 37.5% of the FAC-treated patients and 19.5% of the control patients had remained free of disease. FAC-treated patients who completed 2 years of therapy and in whom adjuvant chemotherapy was started promptly after local treatment had a 48% disease-free survival rate of 4 years. In those in whom the initial manifestation was supraclavicular involvement, the estimated 5-year disease-free survival rate was 42% for patients treated with FAC and 9% for control patients. There were local recurrences in 25% of FAC-treated patients and 23% of control patients (not significant). Distant metastases developed in 50% of FAC-treated patients and 77% of control patients (p less than 0.01). The median disease-free interval was 25 months in the FAC-treated group and 11 months in the control group (p = 0.025). The greatest improvement in prognosis was in patients with supraclavicular involvement; the median disease-free survival was 26 months in FAC-treated patients and 6 months in the control group (p = 0.007). This multimodal approach effectively renders the majority of patients with locoregionally advanced breast cancer free of disease and prolongs the disease-free survival period.

Twenty-six patients with male breast cancer who were admitted to the Center of Oncology and Nuclear Medicine, Istanbul, Turkey, between 1980 and 1988, were analyzed retrospectively. Median age was 60 years. Most lesions were infiltrating ductal carcinomas (92%). Of 26 lesions, 9 were staged as stage II (35%), 14 as stage III (54%), and 3 as stage IV (11%). All but five patients underwent unilateral mastectomy (81%). Postoperative treatment consisted of radiation therapy combined with chemotherapy in 11 patients (42%), chemotherapy with or without hormonal therapy in 4 (15%), radiation therapy alone in 10 (38%). Radiation therapy was delivered for a mean total radiation dose of 52 +/- 2 Gy (range 30-60 Gy). Chemotherapy consisted of cyclophosphamide, methotrexate and 5-fluorouracil (CMF) in most patients (60%). FAC regimen (5-fluorouracil, Adriamycin, and cyclophosphamide) was given to 6 patients (40%). Six patients were known to have died of breast cancer during follow-up (23%). Fourteen patients were NED (no evidence of disease) at last follow-up (54%). Overall actuarial 5-year survival was calculated to be 37%, and median actuarial survival was 46.6 months. Actuarial 5-year disease-free survival was 27%, and median actuarial disease-free survival was 47.1 months. Only one patient had a local recurrence, and eight patients had 13 distant metastases (31%). Age (P = 0.023), tumor stage (P = 0.055) and nodal status (P = 0.013) were the most significant prognostic factors correlated with the overall survival.

Considering the recommended dose of the docetaxel/doxorubicin combination (75 mg/m2 and 50 mg/m2, respectively), we decided to proceed with a pilot program in untreated metastatic breast cancer aimed at defining a multidrug regimen that could be later randomly compared with a standard doxorubicin-containing polychemotherapy regimen with equidoses of doxorubicin such as the FAC protocol (5-fluorouracil 500 mg/m2, doxorubicin 50 mg/m2, and cyclophosphamide 500 mg/m2) in first-line metastatic and adjuvant treatment of breast cancer patients. We proceeded with a pilot phase II study of the TAC combination, which consists of docetaxel 75 mg/m2 as a 1-hour infusion preceded by doxorubicin 50 mg/m2 and cyclophosphamide 500 mg/m2, both given as an intravenous bolus. Three hundred seventy courses were delivered in 54 anthracycline-naive patients, among whom 62% had visceral metastases. Median relative dose intensity was above 98% for all drugs. Grade 4 neutropenia was the main toxicity (70% of cycles) and the incidence of febrile neutropenia and infection was acceptable (6% and 0.8% of cycles, respectively). Acute and chronic extrahematologic toxicities were mild, mostly grade 2, and the docetaxel-specific toxicities (fluid retention, nail changes, etc) were not major clinical problems; no patient was discontinued due to fluid retention. The major response rate was 73% overall and 79% in measurable disease. Time to progression and survival are still under evaluation. The TAC combination is an active and well-tolerated regimen that is the basis of two currently open, pivotal, randomized phase III trials comparing TAC with FAC in the metastatic and adjuvant treatment of breast cancer.
