[The effectiveness of chemoradiotherapy of malignant tumors using platidiam]

The effectiveness of polychemotherapy (platidiam + chemoradiation treatment) for extensive cancer of the esophagus, stomach and lung was studied in 71 patients. Response rate in esophageal cancer patients after platidiam, methotrexate and prospidin was 31%, which increased to 65% after irradiation. In stomach cancer patients treated with platidiam, 5-fluorouracil and vincristine, antitumor effect was registered in 30% and a 50% regression of tumor following radiotherapy--in 37%. In small cell lung cancer group, chemotherapy (platidiam + cyclophosphamide + vincristine) was effective in 37.5% and in 83% when combined with radiotherapy.
