%X BACKGROUND: When lung cancer is combined with concurrent tuberculosis (TB), it increases the difficulty of diagnosis and treatment, leading to missed and/or misdiagnosed cases.
OBJECTIVE: To provide reference markers for the clinical diagnosis of patients with lung cancer complicated by active pulmonary TB (APT).
METHODS: The concentration of survivin in diseased tissue, and miR-29a and IGRAs interferon gamma (IFN-γ) in serum were evaluated in 25 patients with non-small cell lung carcinoma (NSCLC) complicated by APT, 32 patients with NSCLC and 30 patients with APT.
RESULTS: The expression of miR-29a in serum of patients with APT was higher than in patients with NSCLC complicated by APT (least significant difference (LSD)-t = 4.724, p < 0.001), and the NSCLC group (LSD-t = 6.619, p < 0.001). Furthermore, patients with NSCLC complicated by APT had higher miR-29a concentration than the NSCLC group. The rate of positive survivin expression in NSCLC (χ2 = 23.418, p < 0.001) and NSCLC combined with APT group (χ2 = 17.160, p < 0.001) was significantly higher than in patients with APT. The concentration of IFN-γ in serum of the NSCLC complicated by APT group (LSD-t = 2.912, p = 0.004) and the APT group (LSD-t = 4.452, p < 0.001) was higher than in the NSCLC group. The level of IFN-γ in serum of the NSCLC complicated by APT group were higher than in the APT group, but there was no statistical difference.
CONCLUSIONS: The levels of MiR-29a, Survivin and IFN-γ was helpful for differential diagnosis of lung cancer and tuberculosis.
