Objectives: The objective of this paper is to assess the results of surgical treatment retrospectively in a consecutive series of 85 patients with peripheral non-small cell lung cancer (NSCLC) invading parietal pleura and chest wall. Methods: From 1994 to 1998, of the 572 patients having pulmonary resection for NSCLC, 29 patients with neoplasm involving the parietal pleura (group I) and 56 with that invading the chest wall (group II) underwent resection. Results: The operative mortality rate was 3.4% in group I and 1.8% in group II. In groups I and II, pathologic N status was N0 in 20 (69%) cases, N1 in five (17%), N2 in four (13.8%) and 44 (78.6%), seven (12.5%), five (8.9%), respectively. An incomplete resection (R1) was performed in two (6.9%) patients in group I and seven (12.5%) in group II. Postoperative radiotherapy was carried out in 18 patients in group I and 46 in group II. Systemic chemotherapy was also administered in seven patients in group I and eight in group II. There was a significant difference in adjuvant therapy between the groups (P , 0:05). Two patients (R1) in group I (7.4%) and 12 patients (seven patients R1 1 5 R0) in group II (24%) had local recurrence. There was no significant difference in local recurrence between the groups (P 1⁄4 12). Follow-up was completed in 79 cases (28 in group I and 51 in group II). Median survival for groups I and II were 27 ^ 6 and 16 ^ 4.6 months, respectively. Five-year survival was longer in group I than in group II (33 vs. 14%), but there was no significant difference (P 1⁄4 13). Conclusions: We found similar survival rates for extrapleural resection in limited parietal pleura invasion and chest wall resection in exceeded-beyond-parietal pleura invasion. The completeness of resection is important in both groups. q 2002 Elsevier Science B.V. All rights reserved.
