Breast cancer remains a major cause of morbidity and early death in women worldwide. Despite the responsiveness of advanced breast cancer to a number of chemotherapeutic and hormonal agents, long term outcome remains poor. The introduction of paclitaxel with a novel mechanism of action has kindled a ray of hope. Combination of paclitaxel with anthracyclines are being tried, with varying degree of success. Twenty patients with metastatic or locally advanced breast cancer were treated with Paclitaxel (175 mg/m2) and Epirubicin (80 mg/m2) administered sequentially. Each patient received 3 to 6 such cycles at 3 weekly intervals. A response rate of 85% (95% Confidence Interval (CI) 69%-100%) was observed in these patients with 25% (95% CI 6%-44%) achieving complete response. A response rate of 100% was observed in the six patients with locally advanced disease who had not received any chemotherapy earlier. Grade III neutropenia occurred in 5 patients and was reversible in all the cases. This combination is well tolerated. Its efficacy is being compared in a randomised trial with CAF regime in advanced breast cancer in our center.

Two cases of recurrent breast cancer are reported in which chemotherapy with mitoxantrone proved remarkably effective. Case 1 was a 61-year-old postmenopausal female. At 32 postoperative months, multiple metastases of lung and bone were found. Following unsuccessful treatment with anthracyclin and an antiestrogenic agent, we used MVP modified therapy (mitoxantrone (MIT) 16 mg and vincristine (VCR) 1.6 mg once per 4 weeks and medroxyprogesterone acetate (MPA) 1,200 mg/day) and 5'-deoxy-5-fluorouridine (5'-DFUR) 800 mg/daily. After 12 cycles were performed, the patient showed a partial response (PR) (nearly complete response (CR)) on a chest X-ray and bone scintigram. Case 2 was a 49-year-old premenopausal female. At 42 postoperative months, a local recurrence was found and resection was performed. However, after endocrine therapy with goserelin acetate (ZOL) and chemotherapy with CAF (cyclophosphamide, adriamycin and 5-FU) and UFT, local recurrence and pleural effusion were found 6 months after surgical operation. We then used MVP modified chemotherapy and endocrine therapy with ZOL. The patient showed a PR at 9 cycles after therapy. MVP modified chemotherapy is considered an effective treatment for recurrent breast cancer, especially for adriamycin or epirubicin resistant breast cancer.

A huge mass measuring 13 x 12 cm and wide cutaneous edema were detected in the right breast of a 51-year-old woman. Under a diagnosis of locally advanced breast cancer (T4bN2M1, stage IV) with liver metastases, we attempted sequential neoadjuvant chemotherapy. After three courses of CAF therapy (cyclophosphamide, doxorubicin (DXR), 5-FU), the primary tumor was decreased by 56% and the liver metastases had disappeared. A minor pathologic response was observed. Subsequently, three courses of docetaxel (TXT) administration were carried out. The primary tumor was then decreased by 75% and the axillary metastases had disappeared. Histopathological examination showed gross viable tumor cells in the residual tumor and positive axillary lymph nodes. The only toxic effect was nausea (grade 1) and no major adverse effects were observed. Neoadjuvant chemotherapy with sequential DXR followed by TXT is a useful treatment for locally advanced breast cancer.

A controlled randomized trial was conducted to compare the effectiveness of a conventional dose of CAF therapy with that of a low dose of adriamycin (ADR) therapy for the treatment of advanced Breast Cancer. The doses of medication for the conventional CAF therapy were 100 mg/body of cyclophosphamide (CPA) p.o. daily fort wo weeks, 30 mg/m(2) of ADR and 500 mg/m(2) of 5-fluorouracil (5-FU) i.v. on days 1 and 8 for induction, and 200 mg/body of 5-FU and 20 mg/body of tamoxifen (TAM) p.o. daily for maintenance. Those for the low dose ADR therapy were 15mg/m(2) of ADR i.v. at two-week intervals for one year and 200 mg/body of 5-FU and 20 mg/body of TAM p.o. daily. Eighty patients were entered in this trial. All patients were randomly divided into two groups with stratification for estrogen receptor status. Of 78 patients among them, 38 undergoing the CAF therapy and 40 undergoing the low dose ADR therapy, were evaluated for efficacy assesment. The background factors analyzed were well balanced in both groups. The response rate was 47%(6CR, 12PR out of 38) in the CAF group and 43% (3CR, 14PR out of 40) in the low dose ADR group. There was no significant difference in response rates and survival rates as determined by the Kaplan Meier method between the two groups. The CAF therapy had significantly more toxicity than the low dose ADR therapy. Therefore, it was concluded that this low dose ADR therapy can be regarded as a treatment of choice for advanced breast cancer.

A 52-year-old Japanese woman developed dermatomyositis. She had undergone a standard radical mastectomy for left breast cancer 21 years earlier. Though no physical sign of recurrent breast cancer appeared clinically, levels of tumor markers were abnormally elevated. Therefore, tamoxifen and CAF therapy were given. Further, the clinical course of dermatomyositis almost paralleled the level of serum tumor markers and the clinical course of her recurrent breast cancer. These markers were useful for detecting the recurrence, following the metastatic disease, and monitoring her response to therapy.

A controlled randomized trial was conducted to compare the effectiveness of a CAF therapy including cyclophosphamide (CPA), adriamycin (ADR) and 5-fluorouracil (5FU) with that of CAF plus medroxyprogesterone acetate (MPA) therapy including CPA, ADR and 5FU plus MPA for the treatment of liver metastases from breast cancer. A total of 34 patients with unresectable liver metastases from breast cancer were divided into two treatment groups(CAF and CAF + MPA)with stratification for estrogen receptor status. The response rate was 13%(2PR in 16 patients)for CAF therapy and 22% (1 CR and 3 PR in 18 patients) for CAF plus MPA therapy. There was no significant difference in response rates, median survival periods and survival rates between the two treatment groups. However, CAF therapy had significantly more toxicity than did CAF plus MPA therapy. The findings of this study suggested that CAF plus MPA therapy is a well-tolerated and effective treatment for patients with liver metastases of breast cancer.

A multi-center, randomized controlled collaborative study was conducted in 310 institutions located thruoughout Japan for 3 years and 9 months from February 1985 until October 1988 to evaluate the efficacy of post-operative adjuvant therapy for patients who had previously undergone curative surgery for treatment of Stage III a breast cancer. Patients with estrogen receptor-positive [ ER(+)] breast cancer were treated with two types of regimens, ie, cyclophosphamide+adriamycin+fluorouracil (CAF; 2 cycles) +Futraful(FT) or CAF (2 cycles+FT+tamoxifen (TAM), and the clinical benefit of additional use of TAM was evaluated. Of the 509 ER(+) patients registered for the trial, 473 patients (92.9%) were eligible for evaluation.The 5-year survival rate was 77.2% for the CAF+FT group and 74.6% for the CAF+FT+TAM group, and the 5-year disease-free survival rate was 56.7% for the CAF+FT group and 59.2% for the CAF+FT+TAM group. Neither the survival rate nor the disease-free survival rate differed significantly between the groups. Analyses by factor revealed that the 5-year disease-free rate for lymph node-negative patients in the CAF+FT+TAM group was significantly higher than that for the corresponding patients in the CAF+FT group. No differences were noted in the incidence of adverse reactions between the two treatment groups, other than an increase in LDH (the frequency of which was higher in the CAF+FT+TAM group than in the CAF+FT group). Patients with estrogen receptor-negative [ ER(-)]breast cancer were treated with two types of regimens, ie, CAF+FT or CAF+FT+adriamycin(ADR), and the clinical benefit of the combined use of intermittent doses of ADR was evaluated. Of the 514 ER(-) patients registered in the trial, 478(93.0%) were eligible for evaluation. The 5-year survival rate was 64.9% for the CAF+FT group and 63.0% for the CAF+FT+ADR group, and the 5-year disease-free survival rate was 59.2% for both CAF+FT and CAF+FT+ADR groups. Neither the survival rate nor the disease-free survival rate differed significantly between the groups. There were no significant differences between these groups in analyses by nodal or menopausal status. The incidences of adverse reactions including anorexia, nausea/vomiting and alopecia were higher in the CAF+FT+ADR group than in the CAF+FT group.

Thirty-two patients with advanced breast cancer refractory to combination chemotherapy with cyclophosphamide (CPA), doxorubicin (ADR) and 5-fluorouracil (5-EU) (CAF) were treated with the combination of mitomycin C, etoposide, doxifluridine and medroxyprogesterone acetate as second line therapy. Observed responses included 6 patients (18.7%) with complete response (CR) and 7 (21.9%) with partial response (PR). Two (50%) out of 4 patients who had bone pain due to bone metastasis noted pain relief. CR or PR were obtained in 4 out of 12 patients who had not responded to the previous CAF therapy. While grade III myelosuppression was observed in 3 patients, other adverse effects were minimal. It is suggested that this combination therapy may be recommended for advanced breast cancer patients as a second therapy.

A 52-year-old woman complaining of breast tumor was diagnosed as having advanced breast cancer (T4bN1M1-Stage IV), with metastasis of multiple organs (lung, liver, mediastinal and unilateral axillary lymph nodes) after which she underwent tumorectomy. Postoperative adjuvant therapy was performed using combined chemoendocrine therapy (CAF + 5'-DFUR + MPA). Following the endocrine therapy, the metastatic lesions of the liver and lung had disappeared. The adverse effects were not remarkable. Complete remission was continued for 2 years and 3 months, and the patient enjoyed a favorable quality of life.

The patient was a 46-year-old women who was treated for axillary lymph node recurrence of breast cancer by a variety of methods, including surgery, chemotherapy, and radiotherapy, but who experienced recurrences in the cervical and mediastinal lymph nodes and skin, and developed hydrothorax and ascites. Although the recurrent foci responded to 4 cycles of CAF chemotherapy, there was concern that the foci would become refractory or resistant to chemotherapy. The administration of paclitaxel was therefore initiated. The patient received a dose of paclitaxel once a week for 5 consecutive weeks followed by a 1-week recovery period (one cycle). After two cycles of the paclitaxel treatment, a marked shrinkage of the lymph nodes and complete resolution of the hydrothorax and ascites were observed. Even though the patient exhibited bone marrow suppression and G-CSF was administered twice for neutropenia, there were no adverse effects except mild alopecia, again suggesting the possibility that paclitaxel is effective chemotherapy for recurrent breast cancer.
