Prevalencia de Linfomas no Hodgkin Gastrointestinales en el Hospital de SOLCA, periodo 2015 – 2019.

Abstract

Introduction: Primary extranodal non-Hodgkin's lymphomas (NHL) are rare neoplasms; however, the gastrointestinal tract is the most commonly affected location. Regarding their global prevalence, they correspond to 10 to 15% of all non-Hodgkin's lymphomas. Objective: To determine the prevalence of Primary Gastrointestinal NHL (GI-NHL) in patients treated at SOLCA Guayaquil in the period 2015 - 2019 by collecting statistical information to establish most frequent anatomical location and histological subtype. Materials and methods: A retrospective and observational study of prevalence, cross-sectional, was carried out from the collection of data from medical records of the Hospital SOLCA Guayaquil. Results: The stomach was the most frequent site of presentation of GI-NHL, followed by the large intestine and then the small intestine. Of the many types of histologic subtypes, the most common were diffuse large B-cell lymphoma (DLBCL) and mucosa-associated lymphoid tissue-type (MALT) marginal zone lymphoma. There was a higher frequency of cases in males, with an average age of 60 years. The usual symptoms were pain, changes in bowel habit and weight loss. Conclusions: Gastrointestinal non-Hodgkin's lymphomas have a prevalence of 1 in 10 patients with NHL, so their level of suspicion should be high when finding a patient with B symptoms without the presence of adenopathies.
