There is paucity of data on non Hodgkin’s lymphoma (NHL) from our population in North-East India. Inthis retrospective study, patients were consecutively followed-up to see the clinic-pathological pattern of NHL,various responses, and pattern of relapses to first line treatment with chemotherapy. All patients in the presentstudy received standard regimen of cyclophosphamde, doxorubicin, vincristine, prednisolone (CHOP) with orwithout rituximab (R-CHOP) as per our institutional protocol as first line therapy. Our study has shown that,in our adult population, the majority of NHL cases present with stage II and stage III disease and extra nodalinvolvement, B-cell lymphomas and diffuse large cell lymphomas being the most common subtypes. Internationalprognostic index was a significant factor for varied responses to treatment. The majority of relapses after completeremission occurred in the first year.
