| Resumen en inglés | Purpose: to determine the factors associated with the detection of a microinvasive carcinoma in the cervical cone of women with a previous colposcopically directed biopsy compatible with cervical intraepithelial neoplasia (CIN) 3 and to evaluate the proportion of involved margins. Patients and methods: we reviewed the medical records of 385 women (mean age: 39 years) submitted to cold conization or conization by high frequency surgery (HFS) with a loop during the period from January 1993 to July 2000. These procedures were indicated on the basis of a biopsy compatible with (CIN) 3. Results: the diagnosis of the cone was compatible with (CIN) 3 in 243 (63%) women and with (CIN) 2 in 13 (3%). Only 10 presented HPV/CIN 1 (3%) and eight had no residual disease in the cone. However, 101 (26%) women presented a microinvasive carcinoma in the cone and 10 (3%) presented a frankly invasive carcinoma. Age, menstrual status and number of deliveries were not related to the severity of the cone lesion. Women with oncologic colpocytology changes suggestive of invasion presented a significantly higher risk of having a microinvasive or invasive carcinoma as determined by final histology (p<0.01), although 52 of the 243 women with CIN 2 or CIN 3 in the cone also showed a suggestion of invasion at colpocytology. Among the women with CIN 2 or 3, the epithelium was white in 44%, dotted in 21%, and mosaic-like in 17%. This proportion was similar for women with a microinvasive or invasive carcinoma, with these images being detected in 37%, 23% and 21% of the cases, respectively. Involvement of the cone margins was significantly higher among women submitted to HFS (49%) than among those submitted to cold conization (29%). Conclusion: the absence of independent clinical and colposcopic factors associated with the detection of a microinvasive carcinoma in women submitted to conization on the basis of a biopsy compatible with (CIN) 3 justifies the conical excision of the squamocolu |
| Resumen en portugués | Objetivo: determinar os fatores associados ao achado de carcinoma microinvasor no cone de mulheres com biópsia colpodirigida prévia compatível com neoplasia intra-epitelial cervical (NIC) 3 e avaliar a proporção de margens comprometidas. Pacientes e Métodos: foram revisados os prontuários de 385 mulheres (média de idade: 39 anos) submetidas à conização a frio ou por cirurgia de alta freqüência (CAF) com alça no período de janeiro de 1993 a julho de 2000. Estes procedimentos foram indicados por biópsia compatível com NIC 3. Resultados: o diagnóstico do cone foi compatível com NIC 3 em 243 mulheres (63%) e com NIC 2 em 13 (3%). Apenas 10 apresentaram HPV/NIC 1 (3%) e oito não tinham doença residual no cone. Entretanto, 101 mulheres apresentaram carcinoma microinvasor no cone (26%) e 10 (3%) carcinoma invasor franco. A idade, o estado menstrual e o número de partos não estiveram relacionados com a gravidade da lesão no cone. Mulheres com alterações da colpocitologia oncológica sugestivas de invasão apresentaram um risco significativamente maior de apresentar carcinoma microinvasor ou invasor no histológico final (p<0,01), embora 52 das 243 mulheres com NIC 2 ou NIC 3 no cone também tivessem sugestão de invasão na colpocitologia. Entre as mulheres com NIC 2 ou 3, 44% apresentaram epitélio branco, 21% pontilhado e 17% mosaico. Esta proporção foi semelhante nas mulheres com carcinoma microinvasor ou invasor, sendo estas imagens encontradas, respectivamente, em 37%, 23% e 21%. O comprometimento das margens do cone foi significativament |
