Sublobar resection for small @entity2 has been debated frequently and is still a controversial issue. The only randomised trial comparing lobectomy with sublobar resections found a significantly higher recurrence rate for the latter, but failed to show significant differences in survival, although survival was better for the lobectomy group. One meta-analysis and several nonrandomised comparisons have confirmed these results. In general, lobectomy and sublobar resections have similar 5-yr survival rates. Local recurrence after wedge resection is higher than after segmentectomy. However, for @entity1 aged >71 yrs, lobectomy and wedge resection are associated with similar survival. For @entity5 of </=2 cm, segmentectomy is equivalent to lobectomy, but survival after segmentectomy is worse if performed for larger @entity5 . For both segmentectomy and wedge resection, @entity5 margins should be >/=1 cm wide to avoid recurrence. For pure @entity133 of </=2 cm, diagnosed intraoperatively with certainty, sublobar resection seems equivalent to lobectomy, and because there is no nodal involvement, systematic nodal dissection may not be necessary. In case of doubt, however, lobectomy with systematic nodal dissection will ensure complete resection and adequate staging. More randomised trials are needed to confirm all these issues.
