Tratamiento de tumores malignos epiteliales de ovario en estadios avanzados. Experiencia del Hospital Italiano de Buenos Aires / Treatment of advanced epithelial ovarian tumor. Hospital Italiano de Buenos Aires experience

Resumen El cáncer de ovario ocupa el tercer lugar en frecuencia entre los cánceres ginecológicos en Argentina. Existe un déficit de información de esta enfermedad en nuestro país respecto al tratamiento y evolución oncológica de las pacientes. El objetivo de nuestro trabajo fue evaluar los resultados perioperatorios y oncológicos, en pacientes con tumor epitelial de ovario con estadios avanzados. Presentamos una cohorte retrospectiva en la que se evaluó la supervivencia libre de enfermedad y la supervivencia global en pacientes con tumores epiteliales de ovario tratadas en el Hospital Italiano de Buenos Aires entre junio del 2009 a junio del 2017. De 170 pacientes incluidas en el estudio, 72 (42.4%) fueron tratadas con una cirugía de citorreducción primaria (CCP), mientras que 98 (57.6%) recibieron neoadyuvancia y luego cirugía del intervalo (CI). La tasa de citorreducción óptima fue de 75% y de 79% respectivamente. No se encontraron diferencias en los resultados perioperatorios, ni en las complicaciones graves entre ambos grupos. La mediana de SLE en el grupo de CCP fue de 2.5 años (IC 95% 1.6-3.1) mientras que en el grupo de CI fue de 1.4 (IC 95% 1.2-1.7) p < 0.001. La mediana de supervivencia global fue de 5.8 años en CCP, y de 3.5 años en CI. En pacientes adecuadamente seleccionadas la CCP presenta mejores resultados oncológicos a la neoadyuvancia y CI. La selección correcta de las pacientes para tratamiento primario es fundamental para definir la conducta terapéutica.

Abstract Ovarian cancer represents the third gynecological cancer in frequency in Argentina. There is a lack of information on this pathology in our country regarding the treatment and evolution of patients who suffer it. The aim of this study was to evaluate the perioperative and oncological results in patients with advanced epithelial ovarian tumor. We present a retrospective cohort in which we evaluated disease-free survival and overall survival in patients with epithelial ovarian tumor treated at the Hospital Italiano de Buenos Aires between June 2009 and June 2017. Of 170 patients included in the study, 72 (42.4%) received primary debulking surgery (CCP), while 98 (57.6%) received neoadjuvant therapy and interval surgery (CI). The optimal cyto-reduction rate was 75% and 79% respectively. No differences were found in perioperative outcomes, or in severe complications between the two groups. The median disease-free survival in the CCP group was 2.5 years (95% CI 1.6-3.1) while in the CI group it was 1.4 (95% CI 1.2-1.7) p < 0.001. The median overall survival was 5.8 years in CPP, and 3.5 years in CI. Faced with a meticulous selection by a group of experts, patients with advanced ovarian cancer treated with CCP present better oncological results than those who received neoadjuvant therapy and CI.

Acute Abdomen Secondary to Ruptured Epithelial Ovarian Cancer during Pregnancy: The Relevance of Teamwork / Abdome agudo secundário à ruptura do câncer do ovário epitelial durante a gravidez: a importância do trabalho em equipe

Abstract Acute abdomen secondary to epithelial ovarian cancer rupture during pregnancy is a rare event. Our aim is to present how the work of a coordinated multidisciplinary team in a case of ruptured epithelial ovarian cancer during pregnancy is feasible to obtain the best results possible. A 34-year-old woman during the 37th week of her first gestation presented with an acute abdomen. During laparotomy, a ruptured 16.5-cm left ovarian tumor was detected; the tumor was extirpated and sent to pathologic evaluation. In the meantime, a Kerr cesarean section was performed, and a healthy female neonate was born. The tumor was diagnosed as a cystadenocarcinoma; therefore, the family and the combined surgical team (obstetricians and a surgical oncologist) decided to complete a definitive radical ovarian cancer surgery: hysterectomy, right salpingooophorectomy, lymphadenectomy, omentectomy and appendectomy. The patient's postoperative evolution was uneventful, and she was sent to adjuvant chemotherapy.

Resumo O abdome agudo secundário à ruptura do câncer do ovário epitelial durante a gravidez é um evento raro. Nosso objetivo é apresentar como o trabalho de uma equipe multidisciplinar coordenada em um caso de ruptura do câncer de ovário epitelial durante a gravidez é viável para obter os melhores resultados possíveis. Umamulher de 34 anos de idade, durante a 37a semana de sua primeira gestação, apresentou um abdome agudo. Durante a laparotomia, foi detectado um tumor ovariano esquerdo com ruptura de 16,5 cm; O tumor foi extirpado e enviado para avaliação patológica. Enquanto isso, uma cesariana de Kerr foi feita, e uma recém-nascida saudável nasceu. O tumor foi diagnosticado como um cistoadenocarcinoma; então, a família e a equipe cirúrgica combinada (obstetras e oncologista cirúrgico) decidiram concluir uma cirurgia radical definitiva do câncer de ovário: histerectomia, salpingo-ooforectomia direita, linfadenectomia, omentectomia e apendicectomia. A evolução pós-operatória da paciente foi sem intercorrências, e ela foi enviada para quimioterapia adjuvante.
