En bloc resection for lung cancer with chest wall invasion.
BACKGROUND
The aim of this study was to retrospectively assess the results of en bloc chest wall plus lung resection for patients with non-small cell lung cancer (NSCLC) invading the chest wall.


METHODS
From January 1986 to December 2000, of 1,820 patients having surgery for NSCLC, 42 (2.3%) patients with neoplasms involving the chest wall underwent en bloc chest wall and lung resection. Patient demographics, preoperative symptoms, operative procedures, tumor cell type and size, removed nodal status, and pathologic stage were summarized. The 5-year survival rates of the groups were compared.


RESULTS
Postoperative staging revealed 28 were T3N0M0, 4 were T3N1M0, and 10 were T3N2M0. The in-hospital mortality rate was 11.9% (5/42). The mean age was 79.0 +/- 2.8 years in the patients who died of complications, which was significantly older than the mean age of 67.9 +/- 8.1 years in the patients who survived the surgery (p = 0.005). The overall 5-year survival was 28.4%. The 5-year survival was significantly longer in the patients with negative (N0) nodal metastasis than in those with N1 and/or N2 nodal metastasis (39.6% versus 7.1%, p = 0.01). Eleven patients had tumor involvement of the parietal pleura. Thirty-one patients had tumor involvement of the soft tissue and/or bone. There was no significant difference of 5-year survival rate between the patients with involvement of the parietal pleura only and the patients with involvement of the parietal pleura and the soft tissue and/or bone (10.9% versus 33.5%, p = 0.94).


CONCLUSIONS
En bloc resection for bronchogenic carcinoma invading the chest wall provides a favorable prognosis in cases without nodal metastasis. Significant postoperative mortality is associated with old age (> 80 years). The 5-year survival rate is not significantly different between the patients with involvement of the parietal pleura only and the patients with involvement of the parietal pleura and the soft tissue and/or bone.
