[Long-term survival after gastrectomy and other surgeries for multiple primary cancers].

Long-term follow-up (from 10 to 32 years) of patients who have undergone surgeries for synchronous and metachronous polyneoplasia is analyzed. Gastrectomy with resection of the colon was performed in 2 patients, right-sided nephrectomy and abdomino-perineal extirpation of the rectum--in 1, pancreatoduodenal resection with right-sided hemicolectomy and abdomino-anal resection of the rectum--in 1 patient. One of the patients with synchronous-metachronous tumors of the stomach and colon over 15 years was operated 5 times with intervals from several years to several months. A total number of adenocarcinomas removed in this patient was 10. Experience of long-term follow-up of patients with gastrointestinal polyneoplasia confirms expediency of these surgeries when direct contraindications (advanced cancer, severe concomitant diseases) are absent.
