Lung resection in cystic fibrosis: a survival analysis

Lung resection may be considered for cystic fibrosis (CF) patients showing localized severe chronic atelectasis and/or bronchiectasis. Nonetheless, literature on survival after surgery is scarce. This study was carried out to assess survival time after partial lung resection. Twenty-one CF patients were operated from 1988 to 2003 and were followed until November 30th, 2004. Survival analysis was performed through Kaplan-Meier method. Mean age at resection was 8.09 years (SD 4.40 years) and two-thirds were females. Z-scores for height, weight, and body mass index as well as FEV1 values showed no statistical significance when comparing values obtained from 2 years before to 2 years after resection. Eleven years after resection, survival probability was 93.8%. Our results suggest that lobectomy or segmentectomy are safe procedures and should be considered in carefully selected patients with unilateral severe symptomatic localized and chronic persistent atelectasis and/or bronchiectasis refractory to conservative management.
