Assigning patients to a particular pTNM subset and stage will allow the most appropriate individual therapeutic decision. The new international staging system developed in 1986 relies heavily on the nodal descriptors Nl, N2, and N3. Lymph node involvement is usually defined as involvement by metastases. However, involvement can also be caused by direct extension complicating […]
One patient died within 30 days of the operation, accounting for a hospital mortality of 1.7%. Only survival of hospital survivors was analyzed (n=57). The cumulative post-operative survival at 5 years was 45.7% (Fig 1). Direct Extension Compared With Hilar and Lobar Metastases The 5-year survival of patients with nodal involvement by direct extension was […]
From 1977 to 1993, 2,009 patients underwent pulmonary resection for bronchogenic carcinoma. From this group, 58 had a nonsmall cell carcinoma that was classified as pTINlMO. Staging was postsurgical, according to the New International Staging System for lung cancer. Before operation, all patients underwent cervical mediastinoscopy with lymph node sampling. Also at surgery mediastinal lymph […]
Stage II non-small cell lung cancer represents a group of patients with varying 5-year survival rates. Of 2,009 patients, we reviewed 58 patients with pTINlMO disease operated on from 1977 through 1994. The N1 status was refined into lymph node involvement by direct extension and/or involvement by metastases (lobar or hilar). The cumulative 5-year survival […]
