BACKGROUND: Jumonji domain-containing 2B, JMJD2B, has been shown to play an important role in the pathogenesis of lung cancer cells. However, the significance of JMJD2B in patients with lung cancer remains to be elucidated. PATIENTS AND METHODS: Seventy-eight patients with resected adenocarcinoma, whose data regarding oncogenic drivers in lung cancer were available, were included in the study. Immunohistochemical analysis was performed with a specific antibody for JMJD2B to investigate JMJD2B expression and the significance of JMJD2B expression in survival after surgery was evaluated. RESULTS: Among the 78 patients, 50 (64%) exhibited JMJD2B immunopositivity. The overall survival (OS) of the 50 JMJD2B-positive patients after surgery was significantly inferior to that of the JMJD2B-negative patients (five-year survival=56.7% vs. 92.6%; log-rank: p=0.01). Multivariate analysis showed that JMJD2B positivity was an independent prognostic factor. CONCLUSION: JMJD2B may be a novel prognostic factor for resected lung adenocarcinoma. Copyright
