REVIEW AND EVALUATION OF LIMITED RESECTION FOR EARLY LUNG CANCER

Limited resection for early lung cancer has been associated with significantly higher local recurrence rates based on previous reports such as those from lung cancer study groups. On the other hand, a few groups demonstrated that patients with small peripheral cancer who undergo limited resection have comparable survival rates with those who undergo lobectomy. Recent advances in radiologic investigation and pathologic analysis have broadened the indications for limited resection. Since the introduction of the adenocarcinoma classification by Noguchi, surgery for localized bronchioloalveolar carcinoma has focused on limited resection. Caution is necessary when performing wedge resection even if 10 mm or less in diameter and in compromised segmentectomy for early lung cancer. Although limited resection is still controversial, intentional segmentectomy for localized bronchioloalveolar carcinoma or less than 20 mm or less in diameter may be recommended without evidence-based medicine. It is important to accumulate further evidence clarifying the survival and function benefits of limited resection. New therapeutic modalities for limited surgery for small-sized lung cancer may increase patient life expectancy.
