Abstract

DNA aneuploidy and high cell proliferation activity determined by DNA flow cytometry are known to be associated with poor prognosis in many human malignancies. The aim of the present study was to determine the long-term prognostic value of DNA ploidy and cell proliferation activity in lung cancer. The material consisted of samples from 290 paraffin-embedded lung cancers (171 epidermoid carcinomas, 62 small-cell carcinomas, 26 adenocarcinomas, and 31 others), of which DNA ploidy and cell proliferation activity as defined by S-phase fraction (SPF) was determined by DNA flow cytometry. DNA aneuploidy was found in 61% of the tumours and the mean (+/- SD) SPF was 13.6 +/- 9.5%. DNA aneuploidy was associated with a high T-stage (p < 0.05) in epidermoid carcinoma, but not in small-cell carcinoma or adenocarcinoma. DNA aneuploidy and high SPF were associated with poor survival in epidermoid carcinoma. However, only SPF (relative risk (RR) = 1.80), N-(RR = 2.46) and M-stages (RR = 2.17) were statistically significant predictors of survival according to multivariate analysis. Regression-tree analysis showed that the prognostic value of SPF was restricted to localized (M0-stage) epidermoid carcinoma. Neither DNA aneuploidy nor SPF was ass...Continue Reading
