Resumen
Avaliar quantitativamente a apoptose (morte celular programada) e a taxa de proliferação celular no espectro das lesões neoplásicas do colo uterino. Materiais e Métodos: Analisamos 81 biópsias cervicais previamente diagnosticadas na Divisão de Patologia do Instituto Adolfo Lutz segundo a classificação da OMS como sendo: neoplasia intraepitelial cervical de grau 1 NIC 1 = 20, NIC 2 = 19, NIC 3 = 23 e carcinoma de células escamosas (CCE) = 19. Foi utilizado o método imunoistoquímico para detecção das células em proliferação (MIB-1) e o método de TUNEL para a apoptose. As células foram contadas através de fotomicrografia digital, sendo que o número variou de 83 a 2975 (média = 1515,62) para MIB-1 e 315 a 3565 para apoptose (média = 1273,24). Resultados: Houve um aumento progressivo nas taxas de proliferação (%) com a severidade da lesão (NIC 1 = 22,7; NIC 2 = 34,5; NIC 3 = 38,3; CCE = 52,6 p < 0,0001). O mesmo foi obtido com as taxas de apoptose (%) (NIC 1 = 0,30; NIC 2 = 0,55; NIC 3 = 0,70; CCE = 1,19 p< 0,0001) e o índice de renovação celular (%) (NIC 1 = 23,0;...
