Diagnosis, Surgical Treatment And Prognosis Of The Bronchioloalveolar Carcinoma

Objective:Bronchioloalveolar carcinoma (BAC) is a subtype of lung adenocarcinoma, which has unique clinical and biological behavior.2011proposed a new classification of surgical specimens of lung adenocarcinoma, the longest diameter≤3cmBAC normalized as adenocarcinoma in situ. Up to now, not yet the disease-related research. In this study, analyzed and summarized its pathological features and diagnostic changes and imaging characteristics, treatment, and prognosis, and further improve the survival rate.Methods:Retrospective analysis of clinical data from2002-1to2006-12months in our department of surgical treatment of BAC patients, and to track postoperative disease severity and survival status, application software and statistical principles to analyze the survival rate and Final prognostic factors. We took the ones which will meet the new classification of cases of adenocarcinoma in situ, a separate grouping, and analysis survival and prognostic factors.Results:The overall prognosis of the patients was no postoperative deaths in the short term, the total5-year-cumulative deposit rate was88.9%, median survival was75.3months. Age, observation period can affect the prognosis, sex, tumor size and singlemultiple nodules can’t. Patients with adenocarcinoma in situ group, with a total of5years old cumulative deposit rate was95.8%, median survival of74.6months. Age and the observation period can affect the prognosis, gender can not.Conclusion:Adenocarcinoma surgical specimens of new classification criteria to cancel BAC name, to re-refine the classification, there is a reasonable, and help guide clinical, but in adenocarcinoma, differentiation, and transformation aspects of rationality need to confirmed by further studies. Imaging data on the performance of GGO, the existence vacuole sign and bronchioles ventilation levy prompt lesions were volt wall-like growth, and the prognosis is relatively good. BAC has a unique clinical presentation and biological behavior, the prognosis is significantly better than other types of lung cancer, if it is found should be the preferred surgical treatment.
