Surgical management of metachronous bronchial carcinoma.
OBJECTIVE
To assess the results of surgery for the treatment of metachronous bronchial carcinoma.


METHODS
From 1985 to 1999, 38 patients were operated on for a metachronous lung carcinoma, accordingly to the criteria of Martini. All tumors were staged using the new International Classification System revised in 1997.


RESULTS
Diagnosis of the second cancer was done at radiological follow-up in 30 asymptomatic patients. Seventeen metachronous locations were ipsilateral. Histology of the metachronous lesion was the same as that of the first tumour in 23 patients (60%). The first resection was a lobectomy (n=35), a pneumonectomy (n=2) and a carinal resection (n=1). The second one was a wedge resection (n=7), a segmentectomy (n=3), a lingulectomy (n=2), a lobectomy (n=9), a bilobectomy (n=1), and a pneumonectomy (n=16). There were five in-hospital deaths (13%). Completion pneumonectomy was performed in 15 patients, with one postoperative death (7%). The overall estimated 5 and 10-years actuarial survival rates from the treatment of the first cancer were 70 and 47% respectively. The 5-year survival rate after the treatment of the second cancer was 32% (median survival: 31 months), including the operative mortality. Survival was negatively affected by a resection interval of less than 2 years and the performance of atypical lung sparing pulmonary resection for the treatment of the second cancer.


CONCLUSIONS
Good long-term results are achievable by the means of a second pulmonary resection in selected patients with metachronous lung cancer. Optimal cancer operations should be applied whenever functionally possible.
