Primary gastrointestinal lymphoma in Kuwait. An 11-yr retrospective analysis of 108 cases

One hundred and eight cases of primary gastrointestinal lymphoma from the files of Kuwait Cancer Control Centre over a period of 11 yr were analysed retrospectively. The occurrence was 47 in the proximal small intestine, 38 in the stomach, 18 in the distal ileum and five in the colon and rectum. The majority of the patients were in stage III. Using a modified Rappaport's classification, lymphocytic lymphoma was the commonest histologic type (60%) as compared to histiocytic lymphoma (19%). Four patients had early IPSID (immunoproliferative small intestinal disease). The ‘Western’ type of lymphoma occurred in the fourth decade while the ‘Mediterranean’ type occurred in the third decade of life. The latter occurred more commonly among people of low socioeconomic background. Chemotherapy was the single most effective mode of treatment. Addition of surgery, radiotherapy or both did not improve the 2-yr survival but did improve the 5-yr survival.
