Relação entre tumores ovarianos epiteliais borderline e francamente invasores: epidemiologia, histologia e prognóstico The relationship between borderline and invasive epithelial ovarian tumors: epidemiology, histology and prognosis
Abstract
Objetivo: avaliar alguns aspectos epidemiológicos, do diagnóstico e do prognóstico em mulheres com tumores epiteliais ovarianos borderline e francamente invasores. Métodos: foram revisados os prontuários de 198 pacientes tratadas no CAISM/UNICAMP de 1986 a 1996. Para análise estatística foram utilizados os testes chi², exato de Fisher, t de Student e curvas de sobrevida pelo método de Kaplan-Meyer comparadas pelo teste log-rank. O seguimento médio das pacientes foi de 50 meses (de 11 a 168). Dos 198 casos, 24 eram tumores borderline (12%) e 174 (88%) carcinomas francamente invasores. Resultados: a média de idade das pacientes com tumores borderline foi significativamente menor que a das mulheres com carcinoma francamente invasor: 43 ± 14,8 anos vs 52 ± 12,6 anos (pPurpose: to determine some epidemiological, diagnostic and prognostic aspects in women with borderline and invasive epithelial ovarian tumors. Methods: the charts of 198 women treated at CAISM/UNICAMP from 1986 to 1996 were revised. For statistical assessment, chi², Fisher's exact and t Student's tests were used when appropriate, followed by survival curves by the Kaplan-Meyer method, compared by the log-rank test. The mean follow-up was 50 months (11 to 168). Results: the overall rate of borderline tumors was 12% (24 cases), and for invasive carcinoma, 88% (174 cases). The mean age of the patients with borderline tumors was significantly lower than that of those with invasive carcinoma (43 ± 14.8 years vs. 52 ± 12.6 years, p<0.002). The most frequent histologic types were the serous (81 cases: 41%) and the mucinous (46 cases: 23%) tumor. The women with borderline tumors had their diseases diagnosed in earlier stages when compared with the invasive carcinoma patients (p<0.0001). The frozen biopsy, performed on 77 patients, showed a high agreement with the paraffin fixed tissue in the invasive carcinoma cases. However, in borderline tumors, the rate of failure was higher (13%) and the major rate of failure was in mucinous tumors. Regarding prognosis, the survival rate was significantly higher in borderline tumors (p<0.001). Conclusions: women with epithelial ovarian tumors were younger, presented the disease at earlier stages, and had a better prognosis when compared with those with invasive carcinoma.
