    • Abstract

    Background:
    The prevalence of lung cancer increased in the recent years in Indonesia, meanwhile pulmonary tuberculosis (TB) is still a major public health problems in this community. Malignancy such as lung cancer increase the risk of tuberculosis infection and reactivation, therefore evaluation of tuberculosis among lung cancer patients is needed
    
    Methods:
    Newly diagnosed, therapy-naive advanced NSCLC subjects were enrolled from a referral respiratory hospital Persahabatan Hospital Jakarta Indonesia between 2014-2015. Active pulmonary tuberculosis were diagnosed by Xpert MTB/ RIF from induced sputum and LPA M. TB culture. Latent Tuberculosis Infection (LTBI) was determined by Quantiferon-TB Gold-In-Tube (QFT-GIT). Demographic and clinical characteristics were evaluated.
    
    Results:
    Of 50 lung cancer subjects enrolled, 30 (60%) men with mean of age 55 years old (31- 74 years old). Eighty five percents were adenocarcinoma (42 subjects) and 15% squamous cell lung cancer. Most of them were at end stage (87% stage IV and 13%stage IIIB) with WHO performance status (PS) 1 to 3 (20 % PS 1, 70% PS 2 and 10% PS 3). Comorbidities among this group were COPD (3 ssubjects), diabetes mellitus (2 subjects), hypertension (4 subjects), congestive heart failure (1 subjects). Active tuberculosis were diagnosed in 2 % (1 subject). Based on Quantiferon results, 14 % were positive (7 subjects) and classified as latent tuberculosis infection (LTBI); 60% (30 subjets) classified as non-LTBI (negative Quantiferon result) but 12 (24%) indeterminate cases. The characteristics of LTBI patients were 67% men, two third were adenocarcinomas, 80% stage IV of lung cancer, 80% having WHO PS 2 and 3, 50% were underweight (body mass index (BMI) < 17.5.
    
    Conclusion:
    Active pulmonary tuberculosis and latent tuberculosis infection is common among newly diagnosed therapy naive advanced NSCLC in this population. Most of them are men, adenocarcinoma, PS 2-3, and half of them were underweight.
