    Abstract:
    A best evidence topic was written according to a structured protocol. The question addressed was whether pulmonary resection is safe and worthwhile in patients who have undergone previous pneumonectomy. A total of 141 studies were identified using the reported search, of which 8 represented the best evidence to answer the clinical question. Studies on multiple lung cancers with patients undergoing subsequent pulmonary resection after previous pneumonectomy, without outcome data specifically for this group of patients and case reports, were not included in this analysis. The authors, date, journal, country, study type, population, outcomes and key results are tabulated. All studies were retrospective. In total, 102 patients underwent pulmonary resection after contralateral pneumonectomy, of which 96 had sublobar resections and 6 had lobectomies. Postoperative complications, reported in four of the eight studies, ranged from 21 to 44% (mean from four studies 36.8%). Four of the eight studies reported no mortality after pulmonary resection following pneumonectomy, whereas the other four reported mortality rates from 6.7 to 43%. For patients undergoing sublobar resections, the postoperative mortality was 6.2% (6/96), while for those submitted to lobectomy, mortality was 33.3% (2/6). Five-year survival rates ranged from 14% for metastatic disease to 50% for metachronous lung cancer. Due to the infrequent situation of a patient being considered for a pulmonary resection after contralateral pneumonectomy, this analysis was based on a limited number of patients from eight reports. Nevertheless, analysis of the data suggests that pulmonary resection for metastatic or metachronous disease can be performed with acceptable morbidity and low mortality in appropriately selected patients who have previously undergone a pneumonectomy. Sublobar resection is the treatment of choice whenever possible, for which long-term results are rewarding especially for patients with metachronous lung cancer.
