PURPOSE: To identify factors associated with lymphoma in patients with prior Mycobacterium tuberculosis infection.
METHODS: A retrospective case-control analysis was performed in a highly tuberculosis (TB)-endemic area. Patients with a history of TB before the diagnosis of lymphoma were retrospectively identified. Inpatients with lymphoma (n=1,057) and pathologically confirmed benign diseases (n=12,916) were consecutively enrolled at Xinjiang Medical University Cancer Hospital between January 2016 and December 2019.
RESULTS: The proportion of TB infection in patients with lymphoma (n=148, 14.0%) was significantly higher than that in the control (benign diseases) group (n=175, 1.4%) (p<0.0001). The frequencies of TB infection in patients with Hodgkin lymphoma, B-cell non-Hodgkin lymphoma (NHL), and T/NK-cell NHL were 13.6%, 14.6%, and 11.9%, respectively. Relatively high proportions of TB infection were found in patients with chronic lymphocytic leukaemia/small lymphocytic lymphoma (CLL/SLL), marginal zone B-cell lymphoma (MZBL), and diffuse large B-cell lymphoma (DLBCL), at 20.6%, 18.6% and 15.3%, respectively, compared to other subtypes of B-cell NHL. For T/NK-cell NHL, the proportions of TB infection in patients with peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS), and anaplastic large cell lymphoma (ALCL) were 18.2% and 20%, respectively. The multivariate analysis revealed that male sex was an adverse risk factor for lymphoma after tubercular infection. In addition, male sex and older age (>60 years) were associated with B-cell NHL.
CONCLUSION: A high proportion of TB infection was found in patients with lymphoma. In TB-infected patients, older age and male sex were associated with susceptibility to lymphoma, suggesting that screening programmes might be useful for the early detection of lymphoma.
