INTRODUCTION: Gastrointestinal lymphoma (GIL) is the most common extranodal form of non-Hodgkin's lymphoma (NHL) with geographical and age variation of its various subtypes.
AIM: To study GIL in Gharbiah, Egypt and to recognize the treatments employed and their outcomes including survival.
METHODS: This is a retrospective study. Between 2000 and 2002, 40 adult patients with GIL were identified in the Gharbiah population based cancer registry (GPBCR); 26 cases of whom were treated at Tanta Cancer Center (TCC).
RESULTS: GIL in Gharbiah, Egypt represented 6.2% of all GIT cancers. The median age was 47 years with slight male predominance. The commonest primary site was the stomach followed by the colon/rectum then the small intestine (67.5%, 25% and 7.5%, respectively). The commonest histological subtypes were the diffuse large B-cell (41.5%) followed by marginal zone B-cell (39%). The commonest symptoms were abdominal pains followed by vomiting. Only 18% of GILs were surgically resected. Most patients (77%) received chemotherapy with a 60% complete response (CR) rate. Once in CR, relapses are occasional. The median overall survival (OS) and progression free survival (PFS) were 31 and 14 months (95% CI, 13.2-48.7 and 6.4-21.6 months, respectively). Gastric primary site and diffuse large B cell subtype carry a non-significant worse OS and PFS than those of other sites and subtypes.
CONCLUSIONS: GILs in Gharbiah, Egypt are characterized by predominance of male gender, gastric site and marginal zone histology. Survival is worse for gastric and diffuse large B-cell GILs compared to other sites and histologies.
