✦ Synopsis

A study of 187 surgical specimens of tumors of patients with non-small-cell lung carcinomas was carried out by means of flow cyto- metry. Eighty-four percent of the tumors were classified as tumors with abnormal DNA stemlines (DNA aneuploidy). Patients with tumors demonstrating DNA aneuploidy had significantly shorter survival times than those with tumors demonstrating DNA diploidy (p = .009).

Cell cycle analysis was possible in I22 tumors. Patients whose tumors had 0-8% S phase cells died later than patients whose tumors had 9-16% S-phase cells (p = .OW). In addition, patients with tumors with a low fraction of labeled S-phase cells (autoradiography) had a better prognosis than patients with tumors with a high proportion of labeled S-phase cells (p = .041).

## Inactivation of the Rb pathway in non-small cell lung carcinoma (NSCLC) occurs mostly through inactivation of the cyclin-dependent kinase inhibitor p16 INK4A and/or up-regulation of cyclin D1. In order to assess the frequency and the prognostic value of these abnormalities in NSCLC, immunohisto
