In 37 cases of locally advanced breast cancer, arterial administration of adriamycin (ADR), given a total dose of 150 mg in a single dose of 30 mg or 50 mg, was attempted as means of preoperative chemotherapy, and its tumor contraction action in the primary breast cancer and side effects were studied. On the basis of the "Assessement Criteria of Therapeutic Effects on Advanced and Recurrent Breast Cancer" by the Japan Breast Cancer Society, complete response (CR) was noted in 3 cases, and partial response (PR) in 25 cases, with an efficacy rate (CR+PR) of 75.7% (28/37 cases). There was no significant difference in the efficacy rate between the two groups and histological effects were statistically similar. Besides, regarding the difference in the route of administration, the clinical effects were more significant in the group administered from two routes of subclavian artery and internal thoracic artery than in the group injected only from the the subclavian artery. As for side effects, alopecia, leukocytopenia, anorexia, nausea and vomiting were found at high frequencies, and local toxicity was also recognized at a considerable rate, but there was no difference between single dose groups, and these adverse effects were considered to be permissible as far as the total dose up to 150 mg.

The clinical efficacy of two combination chemotherapies, "CAF" (cyclophosphamide, adriamycin, fluorouracil) and "CMcF" (cyclophosphamide, mitomycin C, fluorouracil) were evaluated on the patients with disseminated breast cancer. Two dosage levels were prepared for each combination. After the investigators decided the dosage levels for the patients, patients were assigned to either combination chemotherapy, CAF or CMcF. Among those patients, 138 cases were evaluable. The objective response rates according to "Assessment Criteria of Therapeutic Effects on Advanced or Recurrent Breast Cancer" by Japan Breast Cancer Society were as follows; High dose schedule: CAF 48.4% (15/31) CMcF 40.9% (9/22) Low dose schedule: CAF 31.7% (13/41) CMcF 15.9% (7/44) In both dosage levels, CAF produced higher response rate than CMcF: The toxicities commonly encountered in all treatment groups were anorexia, nausea and vomiting, as well as leucopenia. Alopecia in CAF and thrombocytopenia in CMcF were characteristic side effects.

12 patients with metastatic cancer were treated with the substituted indazole carboxylic acid Lonidamine at oral daily doses of 270 mg/m2. Toxicity, consisting mainly of myalgias, somnolence, hyperesthesia, anorexia and vomiting, generally decreased or disappeared over time despite continuing drug administration at unmodified dosage. Myalgias and hyperesthesias were markedly relieved with prednisone 5 mg twice daily. No laboratory abnormalities were seen. Partial responses were observed in a patient with hypernephroma and in a patient with breast cancer. Disease-oriented phase II studies with this new anticancer agent are warranted.

Lonidamine, a substituted indazole carboxylic acid with unique effects on cellular respiration, was studied in 27 patients with advanced malignancies. Of the 18 evaluable patients, 5 had small-cell lung cancer, 3 had non-small-cell lung cancer, 3 sarcoma, 2 breast cancer, and 5 other tumour types. All but 1 had had extensive prior treatment. A partial response was seen in 1 patient with metastatic synovial sarcoma, and tumour growth inhibition was demonstrated in 2 other cases. The major toxicity encountered was myalgia (66.6%) which was incompletely ameliorated by prednisone and required dose reduction in 2 patients and cessation of drug in 3. Other toxicities included auditory changes, anorexia, nausea and vomiting, diarrhoea, skin sensitivity, and conjunctivitis. No added toxicity was seen, when Lonidamine was combined with other chemotherapeutic agents. No correlation between Lonidamine dose and serum lactate levels was seen, although 4 patients showed a progressive increase in lactate levels over time, thought to be related to their increasing tumour burden. 5 patients demonstrated a dramatic fall in serum testosterone levels 4-8 weeks after starting Lonidamine which was accompanied by an increase in luteinizing hormone levels in 3 patients. In summary, modest antitumour activity was demonstrated in 3 patients; moderate toxicity was seen in most patients, but was usually tolerable. Further studies of Lonidamine are warranted in less heavily treated patients, alone or in combination with other chemotherapeutic agents.

In a total of 277 patients with advanced breast cancer treated between July 1977 and November 1983 at Cancer Institute Hospital, there were 26 cases (9.4%) showing hypercalcemia (Ca greater than or equal to 11.0 mg/dl). All these patients had bone metastasis examined by either X-ray films or bone scintigram during clinical course of the disease and confirmed at the time of autopsy, thus an overall incidence of hypercalcemia in 149 patients with bone metastasis was 17.4%. Major clinical signs due to hypercalcemia were gastrointestinal symptoms such as anorexia, nausea and vomiting, renal dysfunction and neurological symptoms but there was no definitive correlation in between clinical signs and values of serum calcium. Among various treatments performed, a combination of hydration, steroids and calcitonin was the most effective. Mean survival time from the diagnosis of hypercalcemia was 288 + days for responders, and 28.8 days for non-responders (p less than 0.001). Seven patients expired due to hypercalcemia and were died suddenly, while others died of renal failures.

Eighty-one patients with a variety of refractory disseminated malignant neoplasms have been treated in the first multiple fixed-dose phase I trial of recombinant leukocyte A interferon (IFL-rA). Each patient received IFL-rA by intramuscular injection, three times weekly for 28 days. Dosages were escalated in different patients from 1 to 136 x 10(6) units per injection. The toxic reactions seen with IFL-rA resembled those of nonrecombinant leukocyte interferon and included fever, chills, fatigue, anorexia, myalgia, headache, occasional nausea and vomiting, and dose-dependent reversible leukopenia and hepatic transaminase elevations. The pharmacokinetics of IFL-rA were also comparable with nonrecombinant leukocyte interferon. Objective evidence of antitumor activity was seen in non-Hodgkin's lymphoma, chronic lymphocytic leukemia, Hodgkin's disease, breast cancer, and melanoma, indicating that IFL-rA, the first genetically engineered biological response modifier available for testing in cancer patients, is biologically active in vivo.

In twenty-nine cases of primary breast cancer preoperative treatment using CPA and FT-207 (or 5-FUDS) was performed to determine their efficacy. Daily dose of each anticancer drugs was as follows: CPA 50-200 mg, FT-207 200-600 mg, 5-FUDS 200 mg, p.o.. The total doses were CPA 1.8 g, FT-207 5.0g, 5-FUDS 3.4 g in average. In 11 cases (37.9%) reduction in tumor size was obtained. According to Ohboshi's criteria, over Grade II a effect was seen in 5 cases (17.2%), while Grade III effect was not seen in any of the cases. Effective cases were more frequently observed among those which received CPA at 25 mg/kg or more, or FT-207 (5-FUDS) at 80 mg/kg or more. Main side effects were G. I tract symptoms such as anorexia and nausea. To obtain definitive conclusion on the clinical significance of use of CPA and FT-207 (5-FUDS) as preoperative chemotherapy for breast cancer, further studies are required.

Thirty-three patients with metastatic breast cancer who have failed prior combination chemotherapy including adriamycin, cyclophosphamide, 5-fluorouracil and methotrexate, were treated with AZQ given on a 5-day I.V. schedule repeated every 4 weeks. The starting doses were 6 or 8 mg/m2/day for poor- and good-risk patients, respectively. There were two partial responses among 29 evaluable patients. Both had soft tissue and/or lymph node involvement. Six patients had stable disease. Myelosuppression, predominantly thrombocytopenia, was dose-limiting. Other toxicities were mild, including nausea, vomiting, anorexia, diarrhea, stomatitis, and malaise. Our results indicate that AZQ given on the 5-day schedule is unlikely to be effective in the treatment of refractory breast cancer.

A phase II trial was conducted in 57 patients with advanced metastatic breast cancer given 2-N-methyl 9-hydroxy-ellipticine (NMHE) as 100 mg/m2 weekly. Evaluation of response, after at least 4 injections, was possible in 46 patients. Two complete regressions (of 3 and 12 months) and 7 regressions of over 50 p. cent were observed, a total regression rate of 19 p. cent. Regression was mainly observed in cutaneous or subcutaneous metastases. No objective regression was noted for pulmonary or hepatic metastases. Bone metastases were not taken in account when assessing response to treatment. Absence of haematological changes must be emphasized. The most frequent side effects were anorexia, nausea +/- vomiting and dryness of mouth. Major toxicity was intravascular haemolysis, observed in 6 of 175 patients receiving NMHE in the Institut Gustave-Roussy, always controlled by symptomatic treatment. This product, of acceptable efficacy in breast cancer treatment, will probably occupy an original place in anti-cancer chemotherapy because of its lack of myelotoxicity.

In 96 patients (95 women--1 man) with osseous metastases from breast cancer suitable for analysis an objective remission was obtained with hydroxy-9-methyl-2-ellipticinium (100 mg/m2 weekly) in 31 cases. These responses lasted from 3 to 17 months. The main characteristic of this compound is its lack of marrow toxicity, a property of value in osseous lesions where marrow is so frequently involved, making difficult the use of conventional chemical drugs. The principal unpleasant drawback is an inhibition of the salivary secretion which causes other side effects such as tongue mycosis, anorexia, and asthenia. Less frequently immunologic disorders and a few cases of renal insufficiency were observed.
