title: Results and prognostic factors in resections of primary tracheal tumors: a multicenter retrospective study. The French Society of Cardiovascular Surgery.
abstract: To determine long-term survival and prognostic factors, 208 patients with primary tracheal tumors were evaluated in a retrospective multicenter study including 26 centers. Ninety-four patients had squamous cell carcinoma, four had adenocarcinoma, 65 had adenoid cystic carcinoma, and 45 patients had miscellaneous tumors. The following resections were performed: tracheal resection with primary anastomosis, 165; carinal resection, 24; and laryngotracheal resection, 19. Postoperative mortality rate was 10.5% and correlated with the length of the resection, the need for a laryngeal release, the type of resection, and the histologic type of the cancer. Fifty-nine percent of patients with tracheal cancer and 43% of patients with adenoid cystic carcinomas had postoperative radiotherapy. The 5- and 10-year survivals, respectively, were 73% and 57% for adenoid cystic carcinomas and 47% and 36% for tracheal cancers (p < 0.05). Among patients with tracheal cancers, survival was significantly longer for those with complete resections than for those with incomplete resections. On the other hand, the presence of positive lymph nodes did not seem to decrease survival. Postoperative radiotherapy increased survival only in the case of incompletely resected tracheal cancers. Long-term prognosis was worsened by the occurrence of second primary malignancies in patients with tracheal cancers and by the occurrence of late pulmonary metastases in patients with adenoid cystic carcinomas.
