    Notizen: Expression of the endochitinase encoding ech42 gene of the mycoparasite Trichoderma atroviride is subject to control by several environmental signals, including derepression by carbon starvation. In order to identify promoter areas involved in control by this condition, we prepared fusions of several mutant forms of the ech42 promoter to the Aspergillus niger goxA gene as a reporter. Removal of a 130-bp fragment comprising a binding site for the carbon catabolite repressor Cre1, an AGGGG element and three separate binding sites identical and highly similar, respectively, to those for the Aspergillus nidulans regulator of conidiation BrlA resulted in a three-fold increase in derepression under carbon starvation. A truncation of the promoter to 196 bp, which removed all of the observed DNA binding motifs, resulted in five-fold derepression. In vitro protein–DNA binding analyses showed that only the BrlA-like sites, but neither the AGGGG element nor the Cre1 binding site, bound proteins from cell-free extracts from carbon-starved mycelia of T. atroviride. Thus this study identifies a new regulator of chitinase gene expression in Trichoderma, a BrlA-like binding motif.

    Notizen: Summary 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.

    Notizen: Summary Sixty-eight patients with “advanced ovarian carcinoma” were entered into an ongoing phase-II trial for remission induction with cis-platinum (DDP) 80 mg/m2 i.v. on day 1 followed by forced saline diuresis, melphalan (L-PAM) 12 mg/m2 i.v. on day 2 and hexamethylamine (HMM) 130 mg/m2 p.o. x 14 days from days 8–21 in six monthly cycles following operative resection and/or staging. Fifty-one patients were evaluable for response, ten had not completed six courses and could not be assessed, two patients died early (one probably of toxicity), and five patients refused treatment and follow-up. Thirty-Two patients had serous, endometrioid or undifferentiated carcinomas of the ovary. Of these, 11 (35%) achieved a pathologically proven complete remission (CR), five (16%) were NED after second-look (residual disease in ovary or removed omentum with all other biopsies and cytology washings negative), eight (32%) achieved a partial remission (PR), and three (12%) had progressive disease. None of the seven patients with clear-cell carcinoma and none of the three patients with mixed Mullerian tumor of the ovary responded. Six of nine patients with tumors of uncertain origin or proven metastasis to ovary did not respond to treatment. These preliminary results indicate that advanced ovarian carcinomas form a heterogeneous group of recognizable neoplastic diseases with striking variation in response to treatment.

    Notizen: Abstract “Fatigue and malaise” (FM) is a frequent, non-specific symptom of cancer patients caused by the disease, its treatment and psychological distress. Since comprehensive quality of life assessment is often not feasible in multicentre clinical trials, short, but clinically relevant, quality of life indicators have to be defined. In a representative subsample of 127 patients in a phase-III randomized small-cell lung cancer trial comparing two different regimens of combination chemotherapy, quality of life was assessed at the beginning of each of the six treatment cycles with a self-rating questionnaire including an early version of the EORTC questionnaire, a mood adjective check list (Bf-S) and a single linear-analogue self-assessment scale (LASA) measuring general well-being. FM, measured with a five-item Likert subscale of the EORTC questionnaire, showed moderate to high intercorrelations with other EORTC subscales assessing disease symptoms, toxicity of treatment, role functioning, personal functioning, restriction of social activity, psychological distress, emotional (Bf-S) and general well-being (LASA). At baseline, FM was one of the most pronounced symptoms. Over the six cycles 43%–31% of the patients complained of moderate to severe fatigue. Over the first two cycles FM tended to decrease, slightly increasing during cycles 3 and 4 and decreasing again before cycle 6. In a multiple regression analysis over the six cycles, 53% of the variance of FM was explained by patient-rated symptoms of disease and toxicity (disease alone: 43%; toxicity alone: 35%). Initial performance status, previous weight loss, treatment arm, cycle number and age predicted the scores of FM over the six cycles. We conclude that, among other disease- and treatment-related scales, FM can be used as a global indicator of quality of life in small-cell lung cancer patients.

    Notizen: Summary Carboplatin, a new platinum analogue, was administered intravenously on a schedule of a single dose every five weeks to 23 patients with advanced malignant solid tumors. Patients were treated at six dosage levels ranging from 200–550 mg/m2 every five weeks. Thrombocytopenia was dose-limiting. At 550 mg/m2 Carboplatin, the median platelet nadir was 65 000/mm3. Leukopenia was common, but usually of mild to moderate degree. Gastrointestinal upset was commonly seen at all dose levels, but 35% of the patients experienced no vomiting. No significant increase of the serum creatinine following Carboplatin was seen. In 16 patients serial determinations of the creatinine clearance were performed. The median base line creatinine clearance was 87 (50–155) ml/min and dropped to a median lowest creatinine clearance of 69 (23–171) ml/min on day four (p 〈 0.05). The median creatinine clearance before the next Carboplatin treatment was 89 (42–155) ml/min. No significant proteinuria or electrolyte disturbances were noted. Carboplatin exhibited antitumor activity in ovarian, endometrial, thyroid and gastric carcinomas. The maximally tolerated dose appears to be 550 mg/m2 every five weeks. A starting dose of 450 mg/m2 seems to be appropriate for Phase II studies. In patients with impaired renal function and/or prior cis-Platin chemotherapy, Carboplatin at doses of 200–500
