Flow cytometric analysis of primary cervical and vulvar carcinomas and their metastases.
In a series of 25 patients with cervical carcinoma and 35 patients with vulvar carcinoma, clinically classified (FIGO) as Stage I and Ib, respectively, DNA ploidy and S-phase cell fraction were estimated in paraffin-embedded samples of the primary tumors and their metastases by means of flow cytometry (FCM). The two groups of patients were selected cases in whom lymph nodes removed at radical operation were histopathologically verified as metastatic ones. Prevailing part of primary tumors of both anatomic sites had diploid DNA content and low S-phase fraction. Irrespective of the DNA content and low proliferative activity the early stage carcinomas behaved aggressively as indicated by the presence of metastases, the DNA content of which corresponded in most of the cases with that of primary tumor. It appears that prediction of the tumor growth based only on cytogenetic and cytokinetic parameters may be connected with difficulties.
