Objective To investigate and evaluate the clinical manifestation, classification, surgical management and postoperative adjuvant therapy of thymic carcinoid, so as to improve the knowledge of the disease. Methods From January 1980 to January 2006, the outcome of surgery and follow-up of 18 cases of thymic carcinoid surgically intervened were retrospectively analysed. In this series, there were 2? exploratory thoracotomy, 2 partial or incomplete resection and 14 complete resections, which included 2 superior vena cava removal and reconstruction. The survival probabilities were calculated by the life tables, and a multivariable analysis of prognosis factors for thymic carcinoid was carried out using Cox regression model. Results Two patients who underwent exploratory thoracotomy died within one year and two years postoperatively respectively, 2 with partial or incomplete resection obtained temporary symptomatic improvement, 1 of 14 performed complete resections associated with Cushing’s syndrome died of septicemia in two weeks postoperatively, and the other 13 cases were in good condition by follow-up of 5 months to 15 years. The survival rate of 3, 5 and 10 years were 72.6%, 60.5% and 40.3%, respectively. According to Cox regression analysis, the factors of influence upon prognosis included lymph node metastasis(P=0047), pathological type(P=0.000), mode of resection (P=0.000) and postoperative adjuvant treatment(P=0018). Conclusion The thymic carcinoid is different from thymoma or thymic carcinoma, and there exist some difficulty in differential diagnosis. It is divided into typical and atypical thymic carcinoid in pathology, There are obvious differences in clinical manifestation and prognosis between typical and atypical carcinoid. The atypical thymic carcinoid has higher malignancy, frequent recurrence or metastasis, and poor prognosis. Complete resection of tumor with the involved surroundings could improve the long-term survival. The adjuvant radiotheraphy and chemotheraphy postoperatively would be benefit to the patients.
