ABSTRACT
INTRODUCTION:
Results of surgery for non-small-cell lung cancer (NSCLC) are poorer after limited resection, wedge and segmentectomy, than after lobectomy. Guidelines recommend avoiding wedge-resection, which new techniques (radiofrequency ablation and cyberknife) tend to replace. This work aimed to study the wedge-resection carcinological value. PATIENTS ANDMETHODS:
NSCLC without previous other cancer history and neoadjuvant therapy measuring less than 31 millimetres and operated from 1980 to 2009 were reviewed. Analyzed variables were location, gender, age, FEVS, type of resection, histology, pT and pN.RESULTS:
There were 66 wedge-resections (10.9%), 32 segmentectomies (5.3%), 507 lobectomies (83.8%), nine postoperative deaths (1.5%), 136 complications (22.5%), 557 complete resections (R0=92%); 72.2% of NSCLC upper lobe location (437/605). Age was more advanced in wedge-resection and segmentectomy, FEVS lower and NSCLC most often a squamous cell pN0 and pStage I carcinoma than in lobectomy. Lymphadenectomy was not performed in half the wedge-resections. Five-year survival rates were poorer after wedge-resection 50% versus segmentectomy 59.8% (P=0.09), and lobectomy 66% (P=0.0035), but the number of recurrences was similar. Multivariate analysis demonstrated that age, FEVS, type of surgery and lymphadenectomy, pN in pTNM were the only prognosis factors.CONCLUSION:
Wedge-resection is less carcinological than segmentectomy when the patient-status and NSCLC location allow performing the latter, but more than the new techniques, because of its pathological yield, when the patient-status and nodule peripheral location allow wedging.Key words
