BACKGROUND: The problem of unexpected neoplastic residual at the bronchial stump after surgery is discussed. Even if the prognostic impact of a macroscopic neoplastic residual at the bronchial stump is well known, the microscopic residual is still uncertain as well as the better therapeutic strategy to face this problem.
METHODS: 43 out of 2350 patients operated on for lung cancer in our Institute from 1976 to 1998 had a neoplastic residual bronchial stump; 16 patients underwent a second surgery and are no more included in this study. 27 patients with a mean follow-up of three years were treated without another operation. Radiotherapy was proposed to all these patients and performed only in 20, while 4 patients were treated with polychemotherapy alone. Postoperative stage was IIIa in 17 patients, IIb in 8 and IIa in 2.
RESULTS: The three year survival rate is 29% (8 patients still alive, 7 of which disease free); 7 received radiotherapy (35% of the whole patients treated with radiotherapy), only 5 complicated by radiation pneumonia without stopping the treatment, and one only chemotherapy. The survival rate after therapy is the same of patients operated on in the same stage without neoplastic bronchial residual.
CONCLUSIONS: The authors are favorable to perform a second look surgery to enlarge bronchial resection in the initial stages and to perform in all cases adjuvant therapy. Attention is given to the meaning of mucosal or extramucosal involvement, to the effectiveness of frozen section examination and the authors' therapeutic suggestions in relationship to stage and histotype are discussed.
