title: [The prospective analysis of laryngeal cancer growth dynamics in compliance with evaluation of DNA content and ploidy in cytologic material].
abstract: The aim of this study was evaluation of DNA ploidy in the cytological samples from patients with laryngeal cancer and comparison a type of DNA ploidy with histological grading (G) and staging of neoplasmatic process. The examinations were performed on 47 patients operated due to laryngeal cancer (3 women, 44 men, mean age 58). Cytological material was collected from squamous carcinoma tissue by imprinting method. Slides were staining by Feulgen method in order to quantitative analysis of DNA by static cytophotometry. In studied material, aneuploid, polyploid and hypoploid tumors were found in 22 patients and diploid tumors were found in 25 cases. Analysis of DNA ploidy type distribution in correlation to G feature showed:--diploid type were dominated in G1 and G2 tumors,--aneuploid and polyploid type were dominated in G3 tumors. Hypoploid and polyploid tumors were appeared in patients with metastases to cervical lymph nodes more frequently than in patients without metastases. Analysis of DNA ploidy complete traditional histopathological diagnosis of laryngeal cancer and may be useful in predicting metastases to cervical lymph nodes.
