title: [Ki-67 and p53 expression as prognosticators of clinical course aggressiveness of squamous cell cancer of the larynx].
abstract: The study used bioptic sampling material from 64 patients with invasive squamous cell cancer of the larynx, aged 34-77 (mean age--56 +/- 1.2), receiving combined treatment at the Center's Clinic, Obninsk. Ki-67 and p53 levels were assayed vs. such clinico-anatomical parameters as tumor size, cell differentiation grade and presence of regional metastasis. The study revealed a significant direct correlation between Ki-67 index, on the one hand, and tumor size, tumor cell differentiation and relapse, on the other. p53 expression in tumor tissue was associated with a relatively high incidence of relapse (p = 0.01). Both markers may be used as prognosticators of survival in laryngeal cancer.
