Popis: | Of 111 patients with non-small cell lung cancer without clinically evident N2 disease 95 underwent mediastinoscopy between 1975 and 1985. In 63 cases mediastinoscopy was positive and in 32 negative. The patients with a positive mediastinoscopy were considered to have inoperable disease. Their 3- and 5-year survival rates were 5% and 0%, respectively. The patients with a negative mediastinoscopy and 16 patients in whom no mediastinoscopy was performed because of a peripheral tumor underwent operation. They underwent complete tumor resection and mediastinal lymph node dissection. Unsuspected N2 disease was found. Their 3- and 5-year survival rates were 19% and 10%, respectively. The better survival rate in the operated group was statistically significant and mainly due to a better survival of the lobectomy group. Multiple regression analysis showed no favorable prognostic factors in the nonoperated group, but in the operated group lobectomy and central location of the tumor significantly improved the prognosis. We conclude that patients with unsuspected stage IIIa non-small cell lung cancer discovered at thoracotomy benefit from complete tumor resection and mediastinal lymph node dissection, especially if the resection can be confined to lobectomy and if the tumor is located centrally. |
