Comparative studies on the behaviour of the plasmatic clotting system and platelet function in surgically treated cancer patients.

By measuring 18 functional parameters of blood coagulation the dynamic pattern of pre- and postoperative blood coagulation was studied in a total of 43 patients with primarily operable solid tumours. The results were compared with those obtained in patients having benign diseases in the same anatomical regions. Results were discussed preferably from the tumourbiological point of view. Changes of blood coagulation occuring in operated cancer patients with benign diseases. Compensatory processes operating in the haemostatic system provide a well balanced coagulation even in cancer patients. Patients with gastric cancer having low adenine nucleotide levels in platelets had a significantly higher risk to die postoperatively than those with normal levels. This indicates metabolic disorder on cellular levels than haemostatic dysfunctions.

[Clinical evaluation of Ftorafur (author's transl)].

The new soviet antimetabolite Ftorafur (N1-2'-Furanidyl-5-Fluorouracil, FFU) has been clinically evaluated in 18 selected patients with various solid tumours. Several of them had been treated before with other drugs. FFU was given to 8 patients as a monotherapy whereas 10 patients received the drug in combination with other therapeutic measures. A total response rate of 9/18 was seen. Three out of 8 patients treated with FFU alone have responded objectively. Due to its low toxicity FFU became a clinically interesting drug which is suitable for long-lasting administration. Its therapeutic activity is similar to that of 5-Fluorouracil. FFU is especially effective in carcinomas of the breast and the gastro-intestinal tract. It can be applied locally or safely be combined with other drugs or with irradiation.

[The present state of chemotherapy of gastric cancer (author's transl)].

The therapeutic results in stomach cancer are still very poor. Especially in advanced stages of the disease, cytostatic treatment is of little value. The most promising drugs available at present are 5-fluoroaracil or its analogues, Mitomycin C, and Chromomycin A3. Proper combinations of cytostatics are expected to become more therapeutic tools. Further chances of improving therapeutic results are seen in the combination of surgery with irradiation and chemotherapy. Such efforts should include individualization of the therapy with regard to factors of the tumor-host relationships influencing the prognosis, and utilization of tumor-biological data.

Comparison of testosterone decanoate, drostanolone and testololactone in disseminated breast cancer--a randomized clinical study.

It can be said that a single hormone therapy with testosterone decanoate, drostanolone, and testosterone gave similar rates of objective responses in metastatic breast cancer. The presented randomized study has been done to prove whether an additional chemotherapy to hormone applications would further improve therapeutic results. During an observation period of 10 to 16 weeks testosterone decanoate and testolactone in combination with cyclophosphamide have more benefitial effects on the patients than drostanolone plus cyclophosphamide. The combination therapy augmented the rate of objective responses from 22-25 percent to 46-55 percent.

[Cancer chemotherapy of inoperable bronchial carcinomas (author's transl)].

The nowadays' therapeutic results in bronchogenic cancer are rather poor. However, chemotherapy-promises some improvements in remission rates and survival. These results are achievable as well as by mono and by polychemotherapy. The current clinical studies are aimed at optimal application regimes of the drugs beeing at hand. Cyclophosphamide, Methotrexate and Adriamycin are the most effective drugs for montherapy. Alkylants and Methotrexate are especially effective in the oat cell carcinomas. Many cases seem to be more benefited by polychemotherapy than by monotherapy. However, a randomized clinical trial is presented which shows that a montherapy with Adriamycin gave the same results as polychemotherapy. In the case of bronchogenic carcinoma a simultaneously given polychemotherapy is more effective than a sequentially given one. Novel approaches aiming at further improvement of therapeutic results should more consider individual tumour-biological parameters of the tumour-host relationships and possbilities of pharmacological influences upon hemostasis, tumour vascularisation and immunological defense system.
