Abstract
The proliferative activity of pharyngeal carcinoma has been investigated by means of monoclonal antibody PC10 against proliferating cell nuclear antigen (PCNA/cyclin) and argyrophilic nucleolar organizer region (AgNOR) analysis in formalin-fixed, paraffin-embedded biopsies from 45 primary squamous and undifferentiated carcinomas, prior to therapy. The correlation between AgNOR counts and PCNA(PC10) scores was highly significant (r=0.73;PP=0.0003) or the percentage of PCNA(PC10)-positive cells (P=0.0001). Our results indicate that both AgNOR counts and PCNA(PC10) scores are reliable markers of the proliferative activity of pharyngeal carcinoma in small, routinely processed biopsies, in which they can allow simultaneous evaluation of the histology and tumour cell kinetics.Keywords
