Randomized trial of low- versus high-dose medroxyprogesterone acetate in the induction treatment of postmenopausal patients with advanced breast cancer.

In a randomized trial, 210 postmenopausal women with advanced measurable breast cancer were allocated to two different schedules of medroxyprogesterone acetate (MPA). In the induction phase they received either 1,000 mg intramuscular (IM) MPA (high dose) daily or 500 mg IM MPA (low dose) twice weekly for four weeks. The maintenance treatment consisted of 500 mg MPA IM once weekly for all patients. In total, 184 patients were considered evaluable. The response rate was significantly higher (p = 0.004) for patients receiving high-dose MPA (30 [33%] of 91) as compared to the women receiving the low-dose regimen (14 [15%] of 93) and was consistent across all prognostic subgroups. These prognostic subgroups included soft-tissue and osseous metastases, two metastatic sites, patients greater than 60 years, disease-free interval greater than 60 months, no prior chemotherapy, patients with a response to the last hormonal treatment before MPA, unknown estrogen receptors, and positive progestin receptors. The two different schedules of MPA did not influence the time to progression and the survival. Toxicity was similar in both regimens. These results confirm that a higher response rate can be achieved with a more intensive MPA schedule. This treatment may represent an ideal second-line choice in the endocrine therapy of advanced breast cancer; however, its role as a first-line treatment remains to be defined.

Combination chemotherapy for non-small cell lung cancer with doxorubicin and mitomycin or cisplatin and etoposide.

The combinations of doxorubicin (40 mg/m2 iv every 3 weeks) and mitomycin (12 mg/m2 iv every 6 weeks) or cisplatin (80 mg/m2 iv every 3 weeks X 3, then every 6 weeks) and etoposide (80 mg/m2 iv on Days 1-3 every 3 weeks X 3, then every 6 weeks) were evaluated in a randomized phase II trial in 77 patients with measurable or evaluable non-small cell lung cancer. No patient had been pretreated with prior chemotherapy. The overall response rate for the doxorubicin and mitomycin regimen was 11% and for the cisplatin and etoposide regimen was 23%. Responses lasted a median of 5.5 months. Median survival was 7.0 months for the doxorubicin and mitomycin regimen and 8.0 months for the cisplatin and etoposide regimen. One treatment-related death was observed after doxorubicin and mitomycin in a patient who had received radiation therapy immediately prior to study entry. Otherwise, the hematologic toxicity of both chemotherapy regimens was moderate, with only six patients (10%) having World Health Organization grade 3 toxicity and no patients having World Health Organization grade 4 toxicity. However, subjective tolerance gastrointestinal upset) of the cisplatin and etoposide combination was poor.

[Breast cancer: a glimmer of hope?].

The current curability of breast cancer is reviewed. The four different stages of the disease are considered: operable breast cancer, primarily inoperable cases, local recurrences and advanced, metastatic disease. Despite progress in recent years, the latter three stages of the disease must still be regarded as incurable. Furthermore, it is still too early to provide a definite assessment of the relative merits of adjuvant chemotherapy in operable breast cancer. In view of the wellknown heterogeneity of the disease, a longer follow-up will be required for all the studies carried out in the last decade. However, currently available data suggest that adjuvant chemotherapy is increasing overall survival after radical surgery, at any rate in some subsets of patients.

Concurrent or sequential use of cytotoxic chemotherapy and hormone treatment in advanced breast cancer: report of the Swiss Group for Clinical Cancer Research.

In a trial of combined hormone treatment and cytotoxic chemotherapy 464 patients with advanced breast cancer were randomly allocated to either concurrent or sequential treatment. Cytotoxic drugs were given only if the antitumour activity of the hormone treatment was inadequate. Hormone treatment consisted of oophorectomy for premenopausal and tamoxifen administration for postmenopausal patients. Length of survival was better, though not significantly, in premenopausal patients (p = 0.29) treated concurrently and in postmenopausal women (p = 0.17) treated sequentially; the difference was highly significant (p = 0.003) only for postmenopausal women in the low-risk category. The findings suggest that postmenopausal women with metastatic breast cancer should probably be treated primarily by carefully monitored hormone treatment.

A phase II study of cisplatin in advanced gastric cancer.

Twenty patients with recurrent or metastatic gastric adenocarcinoma and prior chemotherapy were treated with cisplatin, 60-120 mg/m2 as a 6-hr infusion repeated every 3 weeks. There were 4 partial responses in 18 evaluable patients. Seven patients had stable disease. Time to progression ranged from 6 to 28 weeks. Median WBC nadir was 3.2 X 10(3)/mm3 (range, 1.5-7.1) and platelet nadir 120 X 10(3)/mm3 (range, 13-220). A transient increase in serum creatinine was observed in 6 cases, and nausea and vomiting in all. We conclude that this drug is active in stomach cancer and that it warrants further trials in combination chemotherapy.

Randomized trial of 3 different regimens of combination chemotherapy in patients receiving simultaneously a hormonal treatment for advanced breast cancer.

We report the results of a randomized trial carried out by the Swiss Group for Clinical Cancer Research (SAKK) and in which 230 patients with advanced breast cancer receiving concurrently a hormonal treatment (oophorectomy for pre- and tamoxifen for postmenopausal women) were randomly allocated to three different regimens of combination chemotherapy. The therapeutic results registered with the two more intensive combinations (LMP/FVP and LMFP/ADM) were similar with regard to response rates, time to progression and survival. The patients receiving the low-dose chemotherapy lmfp showed a statistically significant lower response rate (32%, P less than 0.001) and a shorter survival (P = 0.03) than the results observed in patients treated with the two other regimens. This difference was particularly pronounced, at least regarding survival, in the following subgroups: postmenopausal women, patients with a poor performance status, dominant visceral lesions, two sites of disease and a disease-free interval longer than 12 months. Patients with bony metastases as dominant lesion fared similarly with all three regimens of chemotherapy. This latter subset of advanced breast cancer patients should probably be spared too intensive cytotoxic treatment. This is, to our knowledge, the first report of a randomized trial showing an evident correlation between response rate and survival in various subgroups of patients with advanced breast cancer treated with different chemotherapeutic regimens.

A phase I trial of marcellomycin with a weekly dose schedule.

Marcellomycin, a new anthracycline antibiotic, was administered intravenously on a weekly schedule to 22 patients with advanced malignant solid tumors. Patients were treated at 6 dosage levels ranging from 5 to 30 mg/m2 weekly for 4 weeks. Courses were repeated after a 3-week rest period. Hematologic toxicity was dose-limiting but unpredictable. Of 10 patients treated with weekly doses of 27.5 mg/m2, 3 patients exhibited myelosuppression and 2 died in agranulocytosis. Moderate to severe nausea and vomiting occurred in 19 of 22 evaluable patients. Other toxic effects were non-acute and consisted of mild stomatitis, diarrhea, phlebitis and moderate fatigue in 1-3 patients each. In 17 patients evaluable for antitumor activity no partial or complete responses occurred. One patient with advanced breast cancer showed a mixed response. Marcellomycin given on a weekly dose schedule has unpredictable and erratic hematologic toxicity. The maximally tolerated dose appears to be between 27.5 and 30 mg/m2 weekly. However, no firm recommendations can be given for a dose level that results in tolerable, predictable and reversible toxicity.

Phase II study of amsacrine in solid tumors: a report of the EORTC Early Clinical Trial-Group.

A total of 239 patients with advanced solid tumors were treated in this phase II trial. Amsacrine was administered as a single i.v. dose of 120 mg/m2 repeated at 21-day intervals. The initial dose was reduced to 90 mg/m2 in the case of extensive prior therapy. Some antitumor activity was detected in head and neck cancer but the drug appears to lack significant efficacy in epidermoid lung cancer as well as in carcinoma of the breast, melanoma, renal cell cancer, colorectal cancer and non-seminomatous testicular cancer. Leukopenia was the major toxic effect encountered in this trial and was similar at 90 and 120 mg/m2.

Phase II trial of diaziquone (AZQ) in advanced malignant melanoma.

Forty-two evaluable patients with malignant melanoma received AZQ 27 mg/m2 i.v. every 4 weeks. In 5 patients with poor marrow reserve this dose was reduced to 20 mg/m2. Doses were rapidly escalated when no significant myelosuppression was encountered in previous courses. Twenty-five patients had received no prior chemotherapy. A single partial response was obtained for 3 months. Inconsistent myelosuppression was the main toxic effect in this trial. The median WBC and platelet nadirs were 3200/mm3 (900-19,500) and 105,000/mm3 (33,000-530,000) respectively. In 2 patients leukopenia was complicated by a transient episode of infection. One-third of the patients did not experience significant myelosuppression. Non-hematologic adverse reactions were generally mild to moderate and consisted of nausea and vomiting in 26 patients and alopecia in 1. It is concluded that at this dose schedule AZQ is ineffective against malignant melanoma.

Phase II study of doxifluridine in advanced colorectal adenocarcinoma.

Doxifluridine, a new fluoropyrimidine derivative, was tested in a cooperative phase II trial by the Swiss Group for Clinical Cancer Research in advanced measurable colorectal cancer. The drug was given in a five consecutive day schedule by a bolus intravenous injection at a dose of 4 g/m2 per day and repeated every three to four weeks. Of 42 eligible patients, 40 had no previous chemotherapy. Response was defined in 27 patients having received two or more courses of doxifluridine. Seven responses (26%) were observed. Responses were seen only in sigmoid and rectum primary tumors. Toxicity consisted mainly of leukopenia (53% of the evaluable patients), nausea and vomiting (38%). Other toxicities such as dermatitis, myocardial injury, and hair loss were also observed. Doxifluridine has therapeutic activity, albeit limited, in advanced rectosigmoid adenocarcinoma.

[Long-term outcome in nonmassive pulmonary embolism. Radiologic, scintigraphic and functional correlation].

54 cases of acute pulmonary embolism were followed for 3 to 4 years by serial chest radiography (plain film and tomography) to survey the radiographic outcome of complete and incomplete pulmonary infarcts in man. A perfusion lung scan (99Tcm-MAA), arterial blood gas analysis and spirometric data were recorded at similar time intervals to chest films in 30 patients. Our retrospective study showed that the most common long-term residual radiographic findings were linear pulmonary scars and localized pleural thickening. The analysis of the radiographic abnormalities with the lung scan showed a residual perfusion defect in 29% of cases, with complete clearing of the infarct on chest radiography. Long term impairment of pulmonary function, estimated with arterial blood gas analysis and spirometric tests, was never observed.

[The combination methyl-CCNU, vincristine, 5-fluorouracil and streptozotocin in the treatment of advanced colo-rectal adenocarcinoma].

Sixteen patients with advanced colo-rectal cancer were treated with the combination methyl-CCNU, vincristin, 5-fluorouracil and streptozotocin (MOF-Strepto). Seven cases were previously untreated. A partial remission was observed only in one patient (6%, confidence limits to 95%: 1-17%). Marked gastrointestinal and hematologic toxicity was registered. Based on this experience the authors are unable to confirm other pilot studies claiming major antitumor activity for MOF-Strepto in the treatment of advanced colo-rectal cancer.
