ABSTRACT
@#Objective To evaluate the influence of resection status, pathological type, pathological stage and postoperative adjuvant therapy on prognosis of surgically treated thymic carcinoma. Methods In this retrospective study, 56 patients with surgically treated thymic carcinoma in the Department of Thoracic Surgery, Peking Union Medical College Hospital from January 2005 to December 2015 were enrolled. There were 30 males and 26 females aged 52.1±11.5 years ranging from 22 to 81 years. The survival curve was performed by Kaplan-Meier method. The prognostic factors affecting overall survival (OS) and disease-free survival (DFS) were analyzed by one-way analysis of variance (ANOVA). Results R0 resection was performed in 37 patients (67.9%), and other resections in 19 (32.1%); 13 patients suffered thymic carcinoma with Masaoka stage Ⅰ-Ⅱ, 26 Ⅲ, and 17 Ⅳ. Low-grade thymic carcinoma was found in 42 patients, and high-grade in 14. Postoperative radiotherapy, chemotherapy and chemoradiotherapy were performed on 17, 12 and 18 patients respectively and 9 patients were untreated. Forty-one patients was followed up for 1 to 10 years, and the follow-up rate was 73%. The 1-, 3- and 5-year OS rates were 93%, 74% and 61%, respectively. Resection status and pathological stage affected OS. Postoperative radiotherapy after R0 resection affected DFS, but did not affect OS. Conclusion Most patients with thymic carcinoma after surgery can survive for a long period, and R0 resection is the most important prognostic factor of thymic carcinoma. Postoperative radiotherapy after R0 resection in patients with Masaoka stage Ⅱ-Ⅲ is recommended.
ABSTRACT
@#Objective To investigate the clinical features, diagnosis, treatment and prognosis of ectopic adrenocorticotropic hormone (ACTH) syndrome caused by bronchopulmonary carcinoid. Methods Twenty patients (13 males and 7 females) with ectopic ACTH syndrome caused by bronchopulmonary carcinoid confirmed by surgical pathology were selected from March 2007 to May 2016 in our hospital. We collected and arranged the important clinical data of 20 patients and analyzed carefully. Results The mean age of 20 patients including 14 patients of typical carcinoid and 6 patients of atypical carcinoid was 38.85±15.31 years ranged 13-70 years. All patients had the typical clinical manifestation of Cushing's syndrome. All the thoracic lesions were located by thoracic computed tomography (CT) eventually. The concentration of serum cortisol and ACTH significantly decreased after surgery. Postoperative complications in 3 patients (15.00%) were severe pulmonary infection. Eighteen patients including 13 patients of typical carcinoid and 5 patients of atypical carcinoid were followed up. The median time of follow-up was 31.5 (12-122) months. There were 7 patients of stage Ⅰa, 1 patient of stage Ⅰb, 2 patients of stage Ⅱa and 8 patients of stage Ⅲa in the patients followed up. One patient underwent postoperative radiotherapy, and 4 patients with postoperative chemotherapy. During the follow-up period, one patient relapsed and there was no death. Conclusion Ectopic ACTH syndrome caused by bronchopulmonary carcinoid is a very rare disease. It is every difficult for clinicians to make early diagnosis and draw up plans of treatment without multidisciplinary collaboration. Chest CT is an important method of finding lesions and assessing the viability of surgery. Surgical treatment in early stage will be effective for this disease. And almost all of patients can achieve long-term survival after complete resection of tumors early.
