[Lymph- and haemangiosis carcinomatosa--an important prognostic factor in non-small-cell bronchial carcinoma (NSCLC)].

Between 1 Jan 1984-1 Jan 1990, 199 patients underwent curative (R0) surgery for non-small cell lung cancer. The pathohistological findings showed that a carcinomatous lymphangiosis and haemangiosis (L/H pos.) were present in 26 patients. In six patients, no lymph node metastases were detected. The median (22 mo. vs. 74 mo.) and 5-year survival (25% vs. 41%) were significantly (p < 0.001) higher compared to patients with and without lymphangiosis and haemangiosis carcinomatosa (L/H neg.). There were also significant (p < 0.05) differences in the survival time between pNO L/H neg. and pNO L/H pos. patients (median 74 mo. vs. 15 mo.-5 years 43% vs. 0%).
