[Multiple neoplasms in gastric cancer patients: patterns of development, results of treatment].

Patterns of polyneoplasia development were analyzed in radically operated gastric cancer patients. The second tumors were revealed in 99 of 1255 patients (7,9%) as soon as patients with early gastric cancer manifested primary-multiple malignant tumors almost two times more (15,4%). Among second tumors there were predominantly tumors of the colon, urogenital system, head and neck and also lymphoproliferative diseases.
