Expressão de PCNA, E-caderina e ß-catenina em carcinomas espinocelulares e escamoso basalóide de boca: correlação com o comportamento clínico e prognóstico
Keywords in Portuguese

Abstract in Portuguese
O carcinoma escamoso basalóide (CEB), uma variante agressiva distinta do carcinoma espinocelular (CEC), apresenta predileção para a região de cabeça e pescoço, especialmente base de língua. Um total de 17 CEBs localizados exclusivamente em boca, diagnosticados e tratados no período de 1970 a 2000 no Departamento de Cirurgia de Cabeça e Pescoço e Otorrinolaringologia do Hospital do Câncer AC Camargo, foram comparados a 26 CECs pouco diferenciados (CEC/PD) e a 28 CECs bem a moderadamente diferenciados (CEC/BD com estadiamento e localização equivalentes. Foram avaliadas algumas características clínicas como gênero, idade, raça, tabagismo, etilismo, localização do tumor primário, classificação pelo sistema TNM, tratamento, ocorrência de recidiva tumoral, metástases em linfonodos regionais, a distância e de segundo tumor primário. Além disso, outros aspectos biológicos como a expressão de PCNA e das moléculas de adesão celular E-caderina e β-catenina também foram comparativamente analisados. As probabilidades de sobrevida global e livre de doença foram calculadas pelo método de Kaplan-Meier e a influência das variáveis clínicas e microscópicas no prognóstico avaliada pelo modelo de regressão de Cox. Não se observou diferença estatisticamente significativa na expressão do PCNA entre os três grupos estudados. Para os grupos CEC/PD e CEB, a redução ou ausência da expressão de E-caderina foi observada em mais de 80,0% dos carcinomas sendo estatisticamente significativa quando comparada ao CEC/BD (p=0,019). A forte expressão tumoral da β-catenina foi visualizada, respectivamente, em 26,9% e em 20,8% dos CEC/BDs e CEC/PDs e em 41,2% dos CEBs. Os marcadores imuno-histoquímicos PCNA, E-caderina e β-catenina não constituíram fatores de prognóstico para os pacientes com CEB, CEC/PD e CEC/BD, sendo as probabilidades de sobrevida global e livre de doença acumuladas em 5 e 10 anos semelhantes para os três grupos avaliados. A presença de metástase em linfonodo regional (N+) foi fator de prognóstico independente para os pacientes com CEB, CEC/PD e CEC/BD. Portanto, baseado nestes resultados, podemos concluir que o comportamento clínico e biológico do carcinoma escamoso basalóide e dos carcinomas espinocelulares bem, moderadamente e pouco diferenciados localizados na boca são semelhantes, não sendo influenciados pelo grau de diferenciação celular e/ou pela variante microscópica quando estas neoplasias apresentam estadiamentos clínicos avançados.

EXPRESSION OF PCNA, E-CADHERIN, AND β-CATENIN IN ORAL SQUAMOUS CELL AND BASALOID SQUAMOUS CARCINOMAS: CORRELATION WITH CLINICAL BEHAVIOUR AND PROGNOSES
Abstract in English
Basaloid squamous carcinoma (BSC), a distinct aggressive variant of squamous cell carcinoma (SCC), presents preference for head and neck region, specially base of tongue. Seventeen cases of BSC localized exclusively in mouth, diagnosed and treated from 1970 to 2000 at Department of Head and Neck Surgery and Otorhinolaryngology of Cancer Hospital AC Camargo, were compared to 26 cases of poorly differentiated SCC (PDSCC) and 28 cases of well to moderately differentiated SCC (W/MSCC) matched by stage and tumor site. It was evaluated some characteristics like gender, race, tobacco, alcohol abuse, localization of primary tumor, stage by TNM system, treatment, occurrence of local and cervical recurrence, regional lymph node and distant metastasis and second primary tumors. In addition, others biological features such as PCNA, E-cadherin and β-catenin expression in BSC, PDSCC and W/MSCC were evaluated in relation to their clinicopathological features and prognostic values using Kaplan-Meier method and Cox regression models. No statistically significant differences were found among all three groups in regard to clinical features and immunohistochemical reactivity for PCNA. For groups PDSCC and BSC, reduction or absence of E-cadherin staining was observed in more than 80.0% of carcinomas and it was statistically significant when compared to W/MSCC (p=0.019). A strong expression of β-catenin was observed, respectively, in 26.9% and 20.8% of W/MSCC and PDSCC, and in 41.2% of BSC. The 5-year and 10-year overall and disease-free survival rates demonstrated no significant differences among BSCC, PDSCC and W/MSCC groups and the PCNA, Ecadherin and β-catenin also showed no prognostic value. Metastasis in regional lymph node (N+) was an independent prognosis factor for the oral BSC, PDSCC and W/MSCC patients. These results suggest that the clinical and biological behaviour of BSC, PDSCC and W/MSCC of the oral cavity are similar when matched by clinical stage and tumor site. The histological grade in squamous cell carcinoma or the microscopic tumor variant (BSC or SCC) is not a determinant parameter to predict the prognoses when these tumors present advanced clinical stage.
