[High-dosage methylprednisolone as an antiemetic in cytostatic-induced vomiting].

The antiemetic efficacy of 375 mg methylprednisolone given as slow i.v. push injection was assessed in 27 tumor patients receiving strongly emetic cytostatic treatment. 13 of 27 patients were partially or completely protected from nausea and vomiting. Only minor side effects from methylprednisolone were observed: two patients complained of increased fatigue and four patients experienced facial rash with swelling 1 to 24 hours after the injection of methylprednisolone. High-dose methylprednisolone is an effective antiemetic treatment for patients receiving cancer chemotherapy.

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.

Continuous infusion of high-dose metoclopramide for the prevention of nausea and vomiting in patients receiving cancer chemotherapy.

Fourteen patients undergoing strongly emetic cancer chemotherapy received a total of 33 continuous infusions of high-dose metoclopramide to prevent nausea and vomiting. Metoclopramide 2 mg/kg was given as an i.v. infusion over 15 min followed by continuous infusion over 13 h of 5 mg/kg. The antiemetic response could be evaluated in 12 patients receiving their first continuous metoclopramide infusion. Six patients were partly or completely protected from acute gastrointestinal disturbances. Three patients experienced a short-lived extrapyramidal syndrome during the continuous metoclopramide infusions. Other side effects observed were mild. Thus, high-dose metoclopramide given as a continuous infusion is an effective antiemetic treatment in patients receiving cancer 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.

[Simultaneous or sequential hormono/chemotherapy and a comparison of various polychemotherapies in the treatment of metastatic breast cancer].

Since in the treatment of advanced breast cancer chemotherapy and the various hormonal manipulations seem recently to have reached a plateau of effectiveness when used alone, it is widely assumed that the combination of both treatment modalities could improve therapeutic results. The outcome is reported of a study encompassing 109 pre- and 297 postmenopausal evaluable cases with previously untreated metastatic breast cancer. The patients were randomized either to a concurrent chemo/hormonotherapy or to the hormonal treatment alone, chemotherapy being delayed until the occurrence of tumor progression. All patients were further randomized to 3 chemotherapy regimens (LMFP, LMP/FVP, LMFP/ADM) representing three different degrees of intensity. Pre-menopausal patients tend to live longer with the concurrent combination of both modalities, whereas postmenopausal patients fare better when chemotherapy is delayed until the occurrence of tumor progression with hormonotherapy alone. However, the differences in survival are statistically significant only in postmenopausal patients with a less aggressive tumor ("low-risk"). The more aggressive cytotoxic combinations elicit higher response rates than "minimal chemotherapy", but the differences translate only marginally into different survivals. These findings are discussed with regard in particular to their importance in establishing widely acceptable therapeutic rules for the treatment of advanced breast cancer.

[Prevention of cytostatic-related hair loss by hypothermia of a hairy scalp using a cooling cap].

82 patients treated with adriamycin alone or in combination with other cytostatic agents underwent scalp hypothermia by application of a gel cap. The cap ws applied 10 minutes before the injection of the drugs and maintained until 30 minutes after the administration of the chemotherapy. Prevention of hair loss was achieved in 47 patients (57%). The prophylaxis was successful in 16 out of 21 males (76%) compared with 31 out of 61 female patients (p less than 0.05). No statistically significant difference was found between patients receiving higher or lower doses of adriamycin or between patients wtih or without liver dysfunction. The tolerance of the gel cap was excellent; only one patient did not tolerate the cap because of anxiety during application.

[Stomach cancer. Spontaneous course, therapy and prognosis].

The incidence of gastric cancer in Switzerland has decreased remarkable in the last fifty years and now constitutes 4% of all newly diagnosed neoplasms. Nutrition plays an important role in the pathogenesis of this tumor. The pathology, natural history and the staging of stomach cancer are reviewed, with special emphasis on early gastric cancer. Radiological and gastroscopic diagnosis is correct in almost all cases. Surgery remains as it was 100 years ago when Billroth performed the first gastrectomy, the only curative treatment. In the last few years combination chemotherapy for gastric cancer has been markedly improved, and with modern cytostatic regimens objective tumor responses are achieved in one third to half of patients. The value of adjuvant chemotherapy in radically resected patients remains to be proven. The poor prognosis of gastric cancer can be improved by early diagnosis, better understanding of the pathogenesis of this tumor, elimination of carcinogens from our food and incorporation of effective systemic treatment in the primary treatment plan for stomach cancer.

Levonantradol, a new antiemetic with a high rate of side-effects for the prevention of nausea and vomiting in patients receiving cancer chemotherapy.

Levonantradol, a new antiemetic compound pharmacologically related to the cannabinoids, was given to 17 patients who had experienced severe and protracted nausea and vomiting during previous courses of cancer chemotherapy, and to six patients receiving a first course of strongly emetic cytostatic treatment. Eight patients were partially protected from acute gastrointestinal disturbances. Of the 23 patients, 21 exhibited some toxicity, with six patients exhibiting major affective side-effects and 13 patients complaining of pain at the injection site. Levonantradol is an active antiemetic compound. Due to the rate of side-effects observed in our study however, we would not recommend use of this agent as an antiemetic drug.

Combination hormonotherapy with tamoxifen and fluoxymesterone in patients with advanced breast cancer relapsing on hormonotherapy.

33 patients were treated with a combination of tamoxifen and fluoxymesterone (10 mg t.i.d. each) after progression on prior hormonotherapy (HT). 6 of 22 patients (27%) exhibiting a partial response (PR) or stable disease (NC) on previous HT responded to the combination (median time to relapse 7 months, range 3.5 to 17+ months). 11 (50%) maintained NC (median duration 5 months, range 2% to 9.5 months). No response has been seen in 11 patients who experienced progressive disease during prior hormonal manipulation or who were not evaluable for response to prior HT. The overall response rate was 18% for the patient population as a whole (responders and nonresponders to previous HT), which most probably would be similar to the response rate if these patients received only fluoxymesterone.
