Primary Ovarian Non-Hodgkin's Lymphoma: An 18-year Retrospective Institutional Study and Review of Literature from India.

Abstract

Primary lymphomas of the female reproductive tract are rare and the ovarian extranodal presentation of non-Hodgkin's lymphoma (NHL) accounts for only 0.5% of all NHLs and 1.5% of all ovarian malignancies. We retrospectively reviewed the institutional medical oncology database for newly diagnosed NHL cases between 1999 and 2017. We aimed to study the clinical characteristics, pathology, and outcome of primary ovarian non-Hodgkin's lymphoma (NHL) cases presented to our institution. Weidentified three patients (3.7% of extranodal NHLs and 0.85% of all NHL patients) with primary ovarian NHL from 350 NHL patient records. They underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy followed by six to eight cycles of (rituximab, adriamycin, cyclophosphamide, vincristine, prednisolone (R-CHOP/CHOP), and they attained complete remission. Given the heterogeneity of cancer incidence in India and the absence of state-wise cancer registries, our study argues a pressing need to develop a national representative registry for NHL for accurate incidence, mortality, and survival data. Additionally, fertility preservation is an important issue that must be discussed with women of fertile age and the parents of children.
