[Organ-preserving principle in the surgical treatment of primary multiple cancer of the large intestine].

This paper presents the analysis of 193 surgical cases of multifocal cancer of the colon. The choice of the radical surgery in synchronous tumors depended on the involved portions of the colon, distance between the lesions, cancer dissemination and general condition of the patient. Out of radical interventions, extensive colon resections (atypical and subtotal) made up 18% only (16 of 89 patients). In metachronous cancer, colon resection (n-67) was performed with due consideration of the second tumor site and lymph outflow from the affected zone (39 typical radical operations and 28 resections with removal of interintestinal anastomosis). Postoperative lethality in synchronous cancer reached 11.2%, in metachronous 10.4%, 5-year survival was 59.3% and 57.7%, respectively. The latter figures appeared only a little lower that in solitary colon cancer (63%).
