COMPLICATED FORMS OF NON-HODGKIN’S LYMPHOMAS OF COLON AND SMALL INTESTINE

Purpose: to estimate clinical and morphological features and results of treatment of the complicated forms of non-Hodgkin’s lymphomas of small intestine and colon.

Material and methods. Non-Hodgkin’s lymphomas of small intestine and colon are studied at 189 patients treated in N. N. Blokhin Russian Cancer Research Center during 1985–2010, in 64 cases tumor localized in colon.

Results. 20 were treated by chemotherapy, 9 were operated on for intestinal obstruction in other hospitals and 18 patients were operated on for a tumor of colon without morphological verification, and 17 patients were operated on for tumor complications in N. N. Blokhin Russian Cancer Research Center; tumor was localized in ileum in 74 cases, 26 of them received conservative treatment, 23 patients were operated due to complications in N. N. Blokhin Russian Cancer Research Center, 25 patients was operated on for ileus in other hospitals; tumor was localized in jejunum in 26 patients who all were operated on for ileus; in duodenum lymphoma was located in 25 patients from whom 18 patients were treated conservatively, and 7 had surgery because of complications. Thus, surgical interventions for ileus, bleeding or perforation on primary tumor were made in 92 (48.7 %) patients. Intestinal tumor lesion was primary in 41.0 % and secondary tumor lesion was observed in 58.9 %. 3-year overall survival in patients with uncomplicated lymphomas was 82.5 %, with complicated lymphomas – 70.1 % (p < 0,05).

Conclusions. Development of complications worsens the forecast of the overall survival in non-Hodgkin’s lymphomas of a gastrointestinal tract. It demands special approach to patients with non-Hodgkin’s lymphomas of a gastrointestinal tract because of high risk of development of surgical complications.
