Tuberculosis in patients with malignant disease

Of 2,143 biopsy proven cancer patients seen at our hospital over a six year period, 4 (0.19%) patients developed active tuberculosis (TB) during anticancer therapy or shortly after its completion. The cancer diagnoses of those patients were non-Hodgkin's lymphoma, breast cancer, chronic myelogenous leukemia, and astrocytoma. Institution of antituberculous therapy was successful in three patients, however, the TB course was rapidly fatal in the fourth patient with non-Hodgkin's lymphoma despite therapy. The association between TB and neoplasia is emphasized. TB complicating malignant disorders represents complex problem regarding its early recognition and its managements.
