Abstract

Purpose: To evaluate recurrence rates and risk factors among women with stage IA1 cervical cancer without lymph vascular space invasion managed conservatively.

Methods: retrospective review of women with stage IA1 squamous cervical cancer who underwent cold knife cone or loop electrosurgical excision procedure, between 1994 and 2015, at a gynecologic oncology center in Southern Brazil. Age at diagnosis, pre-conization findings, conization method, margin status, residual disease, recurrence and survival rates were collected and analyzed.

Results: 26 women diagnosed with stage IA1 squamous cervical cancer without lymphovascular space invasion underwent conservative management and had at least 12 months follow-up. The mean follow-up was 44.6 months. The mean age at diagnosis was 40.9 years. Median first intercourse occurred at age 16 years, 11.5% were nulliparous and 30.8% were current or past tobacco smokers. There was one Human immunodeficiency virus positive patient diagnosed with cervical intraepithelial neoplasia grade 2 at 30 months after surgery. However, there were no patients diagnosed with recurrent invasive cervical cancer and there were no deaths due to cervical cancer or other causes in the cohort.

Conclusion: Excellent outcomes were noted in women with stage IA1 cervical cancer without lymphovascular space invasion and with negative margins who were managed conservatively, even in a developing country.

Resumo

Objetivo: Avaliar recidiva e seus fatores de risco em mulheres com câncer do colo do útero estádio IA1 sem invasão do espaço linfovascular tratadas conservadoramente.

Métodos: Estudo de coorte retrospectivo de pacientes com câncer do colo do útero IA1 escamoso submetidas a cone do colo do útero, entre 1994 e 2015, em um centro de ginecologia oncológica do sul do Brasil. Foram revisados e analisados idade no diagnóstico, achados pré-conização, método de conização, margens, doença residual, recorrência e sobrevida.

Resultados: 26 mulheres diagnosticadas com câncer do colo do útero estádio escamoso sem invasão do espaço linfovascular foram submetidas a tratamento conservador, com seguimento mínimo de 12 meses. O tempo médio de seguimento foi 44,6 meses. A média de idade no diagnóstico foi 40,9 anos. A primeira relação sexual ocorreu aos 16 anos (mediana), 11,5% eram nulíparas e 30,8% eram tabagistas atuais ou passadas. Houve um caso de recidiva de neoplasia intraepitelial cervical grau 2 aos 30 meses em uma paciente com vírus da imunodeficiência humana. Não houve pacientes diagnosticados com câncer de colo do útero invasor recorrente, e não houve mortes por câncer do colo do útero ou outras causas.

Conclusão: Os resultados observados após tratamento conservador em mulheres com câncer cervical escamoso IA1 sem invasão do espaço linfovascular com margens negativas foram excelentes, mesmo em um país em desenvolvimento.
