Abstract
Local recurrence after complete resection (R(0)) occur in approximately 20% of patients with stage I disease and in up to 50% with stage III. This study focuses on early detection of stump recurrence by a routine bronchoscopy. Prospective analysis 1 year after surgery between April 2006 and April 2008. 104 NSCLC patients (age 69.1+/-9.6 years) participated in the study; 97 underwent lobectomy and 7 pneumonectomy. 61% were stage I, 25% stage II, 10% IIIA, 5% IIIB and 1% stage IV. 66% had N0, 21% had N1 disease, 9% N2 disease and 4% had N3. Bronchoscopy was performed 12.9+/-3.8 months after surgery. Nine percents had stump polyp, 5 (5%) had a suspicious mucosa. Four of the nine polyps were malignant. Nine other patients had squamous metaplasia and two had squamous dysplasia. Malignant stump recurrence was observed in four cases, all had a stump polyp. All had R(0), but two had short (<1.0 cm) tumor-free bronchial margin, two had N1 disease and two N2 disease. Fisher exact analysis showed short bronchus (p=0.003), N2 vs. N0-1 (p=0.012), and N1 vs. N0 (p=0.011) as significant risk factor for stump recurrence. For stump recurrence, one patient underwent completion pneumonectomy and has no evidence for disease (32.2 months), two pati...Continue Reading
