Surgical treatment of lung carcinoma involving the chest wall.
From 1969 to 1986, 97 patients with chest wall invasion by lung carcinoma (excluding superior sulcus tumours) underwent surgical resection in two hospitals, La Paz (Madrid) and La Fé (Valencia). The same surgical policy was used in both thoracic surgical units: extrapleural pulmonary resection when tumour involved only the parietal pleura (N = 36), and en bloc chest wall resection when the carcinoma extended into the ribs and intercostal muscles (N = 61). The tumour histology was classified according the WHO criteria. Lobectomy or bilobectomy was carried out in 72%, pneumonectomy in 18% and segmentectomy or wedge resection in 10% of the patients. The perioperative mortality was higher in the en bloc resection group 9/61 (15%) versus 2/36 (6%) for extrapleural dissection. The node staging was NO in 58/97 (60%), N1 in 16/97 (16%) and N2 in 23/97 (24%). The probability of survival was calculated by the Kaplan-Meier method collecting data from the perioperative survivors only. The overall 5-year survival was 23% with no significant differences between the en bloc resection and the extrapleural lung resection groups. The most important predictor of survival was the node stage. The 5-year survival for N1 and N2 were 8% and 6%, respectively. These percentages increased to 34% when N0 patients were considered. Other predictors of survival were not significant. The authors conclude that either extrapleural or en bloc chest wall resection are both valid procedures which may be used depending on the depth of local invasion.
