| pubmed-article:17762957 | pubmed:abstractText | Video-assisted thoracoscopic surgery (VATS) has become an attractive surgical procedure, but several issues remain to be resolved. Prognosis after VATS lobectomy is important to evaluate the adequacy of VATS lobectomy as a cancer operation. Interestingly, several investigators, including us, have reported that prognosis after VATS lobectomy was superior to that after open lobectomy in early non-small-cell lung cancer (NSCLC). One of the possible reasons is the low invasiveness of VATS lobectomy. But we considered that patient bias might have some influence favoring VATS lobectomy. To evaluate our hypothesis, we reviewed medical records of stage I NSCLC patients undergoing operation between 1993 and 2002. We compared and evaluated the relationship between patient characteristics and prognosis after VATS and open lobectomy. We focused particularly on histological type, classifying it into four subgroups; (1) bronchioloalveolar carcinoma (BAC), (2) mixed BAC + papillary adenocarcinoma (BAC + Pap), (3) other adenocarcinoma (Other adeno), (4) squamous cell carcinoma + others (Sq + others). | lld:pubmed |
