title: [Evaluation of malignancy of squamous cell lung cancer by clinico-morphological, immunohistochemical and prognostic study of tumor markers].
abstract: An immunological study was carried out in 127 cases of surgical treatment of squamous cell lung cancer. Cryostat sections were used to identify markers of proliferation (Ki-67 and topoisomerase IIalpha), apoptosis (p53 and CAS) and intercellular adhesion (E-cadcherin). It was shown that Ki-67 and topoisomerase IIalpha proliferation rates and CAS expression may be interpreted as additional factors of squamous cell cancer aggressiveness while E-cadcherin expression--as a favorable prognosticator. In cases of Ki-67 in excess of 36%, 5-year survival dropped to 38% as compared with 70% when that index was below 36%.
