Diagnostic Splenectomy: Clinical Profile, Role and Relevance in the Diagnosis of Lymphoma
摘要
There is paucity of data regarding the role and relevance of a diagnostic splenectomy in the diagnosis of lymphoma. A total of 1165 splenectomies done between January 2008- June 2022, were screened for indication, and therapeutic /traumatic splenectomies (n = 1042) were excluded. The clinical spectrum and histopathology of 123 diagnostic splenectomies are described further. 75 (61%) patients were male with median age of 44 years (range 17–74). ‘B’ symptoms were present in 82 (66.7%). Lymphadenopathy was noted in 29 (23.9%) patients, though lymph nodes were not amenable for biopsy or biopsy was non-diagnostic. Preoperative factors including pre-surgical spleen size, lymphocytosis (> 50%), serum LDH and bone marrow reports were analyzed. Splenic histopathology was diagnostic in 89 (72.3%) patients, lymphoma being the most common diagnosis(n = 72;58.5%). Amongst lymphomas, B-cell Non-Hodgkin lymphomas were most common (n = 48;66.6%). Subtyping of lymphoma was possible in 63 cases (87.5%). Splenic histopathology was diagnostic for rare neoplasms/diseases in 5 cases. On univariate analysis, none of the clinical or laboratory parameters were found to be predictive of a histopathological diagnosis of lymphoma. Diagnostic splenectomy has utility in the diagnosis of lymphoma and its subtyping; however, no clinical/laboratory parameters were predictive of a diagnosis of lymphoma.
