Abstract:
To assess the prognostic value of flow cytometric analysis, 61 cases of operated squamous cell lung carcinoma were studied in terms of desoxyribonucleic acid (DNA) nuclear content and percentage of cells in DNA synthesis phase (% S). These parameters were determined on a fresh surgical sample. The S % was obtained in 25 cases. DNA index (DI) and % S were compared with survival and usual clinicopathologic characteristics for the prediction of survival. DNA content classified as DNA-diploid and DNA-aneuploid is not a prognostic factor for survival. DI higher than 2 seems to be predictive but needs confirmation. The % S and multiploidy are not predictive factors for survival.
