ABSTRACT
Abstract PURPOSE To analyze the relation between the cytological findings and telomerase activity (TA). METHODS Cervical samples were evaluated and classified according to the Bethesda System. Telomerase activity was measured total product generated values (TPG) using the TRAP assay (telomeric repeat amplification protocol); data were analyzed statistically using the χ2 test, with the level of significance set at p<0.05. RESULTS The study was conducted on 102 patients. Of these, 3.9% showed normal cytological findings, 8.8% showed cervicitis; 2% showed Atypical Squamous Cells of Undetermined Significance (ASCUS); 67.6% showed Low Grade Squamous Intraepithelial Lesion (LSIL); 11.8% showed High Grade Squamous Intraepithelial Lesion (H-SIL) and 5.9% showed Squamous Carcinoma. Among telomerase-positive samples, the TPG values were cervicitis<normal<ASCUS<L-SIL<H-SIL<Carcinoma. CONCLUSION Results show increased telomerase activity with increasing severity of lesion, supporting the association between TA and type of lesion.
RESUMO
Resumo OBJETIVO Analisar a relação entre os achados citológicos e atividade da telomerase (AT). MÉTODOS Amostras cervicais foram avaliadas e classificadas pelo sistema Bethesda. A AT foi medida como valores de produto total gerado (PTG), utilizando o protocolo de amplificação repetida da telomerase (TRAP); os dados foram analisados estatisticamente usando o teste do χ2, com nível de significância de p<0,05. RESULTADOS Cento e dois pacientes foram analisados 3,9% com achados citológicos normais, 8,8% com cervicite, 2% com células escamosas atípicas de significado indeterminado (ASCUS), 67,6% com lesão escamosa intraepitelial baixo grau (LEI-BG), 11,8 % com lesão intraepitelial escamosa alto grau (LEI-AG) e 5,9% com carcinoma escamoso. Valores PTG para amostras positivas AT foram cervicite<normal<ASCUS<LEI-BG<LEI-AG<Carcinoma. CONCLUSÃO Os resultados mostram um aumento na AT com o aumento da lesão, sustentando a associação entre a AT e o tipo de lesão.
