The burden of tuberculosis among patients with non-small cell lung carcinoma in a tertiary care center

Total 75 patients with biopsy proven, primary NSCLC were recruited and 16 % (12/75) were diagnosed with confirmed TB. Adenocarcinoma (36.48 %) and Squamous cell carcinoma (33.44 %) were the two predominant histopathological subtypes of NSCLC. About 57 (76 %) of them were found to be in stage IV of Lung cancer at initial presentation itself (75 % in group A & 74.6 % in group B; p value < 0.80). A majority of patients (11/12 cases; 91 %) of group A were males with a mean age of 59 ± 7.5 years. The upper lobes of the lung were involved in 65 % (49/75) of the cases and showing a mass lesion on imaging (75 % in group A & 65 % in group B; p value < 0.52). Kaplan Meier survival revealed a median survival time of 11 months in subjects with only NSCLC and a median survival time of 4 months in the group with concomitant TB and NSCLC (p value < 0.44).
