Introduction: Primary Gastrointestinal Lymphoma (PGIL) is a heterogeneous disease in terms of patient characteristics, site, histologic types and treatment modalities. Although rare disease, it is the most common site for extranodal lymphomas accounting for 10-15% of all non-Hodgkin lymphoma and 30-40% of all extranodal lymphoma. Aim: To study the different types of PGIL and its anatomic distribution along with its association with the clinical outcomes. Materials and Methods: This was a retrospective study conducted in Department of Pathology of a tertiary care hospital, South India over a period of five years (2009 to 2013). A total of 61 cases of PGIL were identified, which included both resected surgical and endoscopic biopsy specimens. Histopathological classification of all cases was done based on morphologic and immunophenotypic criteria according to latest World Health Organisation (WHO) 2008 classification. Anatomic distribution of various types of lymphoma and associated clinical features were studied. The cases were then followed-up and survival analysis was also done. Descriptive statistical analysis methods were used to analyse the data. Overall Survival (OS) rates were calculated using Kaplan Meier method for 33 cases. results: There was predominance of men with peak incidence in 7th decade. Abdominal pain was the commonest presenting symptom seen in 77% of the cases. The most common site of involvement was stomach (41%) followed by large intestine (37.7%). All cases of primary GI lymphomas were of non-Hodgkin type. B cell lymphomas (n=54; 88.5%) were more frequent than T cell lymphomas (n=7; 11.5%). Diffuse Large B Cell Lymphoma (DLBCL) was the most common subtype accounting for 67.2% of cases (n=41) followed by MALT lymphoma (n=9; 14.8%). Followup was possible in 33 cases out of which 20 patients (32.8%) died with a median overall survival period of 13 months (95% CI, 7.8-18.2). The five-year overall survival (OS) for 33 patients who were followed-up was 67.2%. conclusion: Diagnosing PGILs correctly according to the recent WHO classification is important so that correct treatment protocols can be followed.
