| Popis: | e20083 Background: Non-Hodgkin Lymphoma (NHL) continues to be in the top 10 of all cancer related deaths. Discrepancies exist among world regions in lymphoma subtype incidence, with a percentage of DLBCL being higher in Latin America versus Nordic countries. T cell lymphomas (TCL) are reported to be more common in east Asia than in the Western hemisphere.The geographic differences in distribution along with under representation of ethnic minorities across all lymphoma subtypes, establish the basis of our analysis at the only NCI-designated cancer center within a Hispanic (H) predominant patient population. We aim to describe our population diagnosed with Hodgkin Lymphoma (HL) and NHL and compare to known overall global and USA statistics. Methods: Observational study, retrospectively analyzed patients with diagnosis of Lymphoma (HL and NHL). The patients received care at UT Health San Antonio, the biggest Hispanic serving Academic Institution in South Texas, between 2008-2018. Key variables included age, gender, race/ethnicity, stage, treatment received, vitality at 3 and 5 years. Continuously distributed outcomes were summarized with the mean and standard deviation and categorical outcomes were summarized with frequencies and percentages. Primary end point was to characterize distribution of HL and NHL by subtypes in our Cancer Center and compare to North American and overall global distribution. Results: A total of 685 patients with lymphoma were identified. Of the NHL subtypes; DLBCL was the most common identified (209, 31%), (FL) was the most common indolent lymphoma (IL) among all demographic groups (123, 26%), followed by HL (116, 17%) which was more common among non-Hispanic (NH) subgroup (73, 63% vs 42, 36%). Among the TCL, CTCL – Mycosis fungoides was the most common subtype (18, 35%) followed by ALK negative ALCL (12, 24%). Incidence by Gender: The percentage of males (M) was slightly higher vs. females (F) in all subtype lymphoma diagnoses, M (352, 51%), F (333, 49%). M had a higher incidence in DLBCL (108, 52% vs 101, 48%), BL (9, 69% vs 4, 31%), and HL (67, 58% vs 49, 44%). Incidence by Race: Total lymphoid neoplasm rates were higher for H (383, 57%) than NH (293, 43%), other (1, 0.2%), not specified (5, 1%). H had a higher incidence in all subtype lymphomas except for Nodular lymphocyte predominant HL (5, 63% vs 3, 37%). Conclusions: Our Hispanic Hispanic Serving Academic Institution, the distribution of lymphomas doesn’t change when compared with previous reported data. Our population and distribution of lymphoma subtypes are similar to global and USA data. |
