Hodgkin lymphoma: epidemiológica! aspects and subtypes diagnosed in a reference hospital in Pará State, Brazil

Abstract

Lymphomas are neoplasias of the immune system originating from B and T cells or natural killer cells which involve lymphoid tissues that are associated with the growth of tumor masses. Hodgkin's lymphoma (HL) is a lymphoproliferative malignancy characterized pathologically by the presence of neoplastic cells with a different morphology called Reed-Sternberg. The aim of this study was to describe the epidemiological profile and subtypes of HL diagnosed from 1996 to 2005 at Ophir Loyola Hospital in Belém, Pará State, Brazil. Of the total, 64.6% (42/65) of patients with HL were male and 35.4% (23/65) of women with ages ranging from 2 to 84 years old. HL subtypes reported rates of 50.8% (33/65), 26.2% (17/65), 15.4% (10/65) and 7.6% (5/65) to nodular sclerosis, mixed cellularity, lymphocyte depletion and lymphocyte predominance, respectively. HL, in the period of the current study (1996-2005), it was more expressive in groups of children and teenagers which prevailed the nodular sclerosis subtype in samples diagnosed in the Pará State.
