Surgical treatment of ciliated muconodular papillary tumor of the lung: a report of 11 cases / 中华胸心血管外科杂志

ABSTRACT

Objective@#To investigate the clinical features of ciliated muconodular papillary tumor(CMPT) of the lung.@*Methods@#We retrospectively reviewed 11 cases with final pathology being diagnosed as CMPT in our department from April 2017 to April 2018. There were 8 males and 3 females with a mean age of(63.7±5.6) years. The clinical data, histopathological features, treatment, and prognosis were reviewed. All patients received CT scan before operation.@*Results@#The radiological features of CMPT include: located peripherally and most in right lower lobe; most CMPT lesions are GGO, some with air spaces in center and few being solid. All patients underwent video-assisted thoracic surgery(VATS) successfully, and there were no severe perioperative complications. The mean operating time was(78.0±28.2) min. The mean blood loss was(37.3±14.9) ml. The mean postoperative hospital stays were(3.45±0.93) days. Pathology examination of all patients were CMPT. Follow-up time ranged from 6 to 18 months and no recurrence was found.@*Conclusion@#CMPT is rare tumor, without specific clinical manifestation, but sometimes misdiagnosed as adenocarcinoma in situ or minimally invasive adenocarcinoma. VATS is feasible and safe for CMPT, and the prognosis is good.
