When an acute abdomen occurs during pregnancy, it poses a huge challenge.1 However, an acute abdomen caused by a ruptured epithelial ovarian cancer during pregnancy is an exceptional disorder.2 3 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.
A 34-year-old woman during the 37th week of her first gestation called her obstetrician because she felt an acute abdominal pain. The patient stated that the pain was sharp, and its intensity increased until it became incapacitating; her physician recommended that she presented to an emergency room immediately. In the meantime, the obstetrician called the surgical oncologist to inform that the patient was in the 37th week of her first gestation and, additionally, she had a big-papillary left ovarian tumor, discovered during her last abdominal ultrasound. Both physicians agreed to evaluate the patient; in the emergency room, the patient presented an evident acute abdomen, and the physicians decided for an immediate laparotomy. Using epidural anesthesia, during the laparotomy, a ruptured 16.5-cm left-ovarian tumor, with intraperitoneal spillage of its inner liquid, was recognized; through the broken tumor wall, many big papillae were observed. A sample from the liquid was taken, and a left salpingo-oophorectomy was completed, and both specimens were sent to the pathology department (at 1 am) for a transoperatory examination. In the meantime, a Kerr cesarean section was performed, and a healthy female neonate weighing 2.35 kg was born. The pathologist diagnosed a ruptured cystadenocarcinoma. With this diagnosis, the patient's husband and the combined surgical team (obstetricians and a surgical oncologist) decided to complete an ovarian carcinoma routine: hysterectomy, right salpingo-oophorectomy, pelvic and para-aortic lymphadenectomy, infracolic omentectomy and appendectomy, with no gross residual tumor; the patient's postoperative evolution was uneventful. The definitive pathologic report was a ruptured moderately differentiated mucinous cystadenocarcinoma (Fig. 1), without tumor capsule invasion and with no metastases to the other surgical specimens. The patient received 6 cycles of carboplatin plus paclitaxel; by the end of the treatment, the patient was well, without tumor recurrence 15 months later.

To our best knowledge, after an extensive literature review (in the PubMed, Google Scholar, LILACS, and Scopus databases), this is the first case of a ruptured epithelial ovarian cystadenocarcinoma during pregnancy favorably resolved in the primary surgery with a cesarean section and a radical surgical procedure. There are two previous reports, one of an endometrioid ovarian carcinoma, and the other of a mucinous cystadenocarcinoma, of cases that presented with rupture during pregnancy4 5, and in both cases, definitive diagnosis and surgical radical treatment for ovarian cancer were performed after the emergency was solved.4 5
Acute abdominal pain during pregnancy entails a huge challenge,1 and when indicated according to specific clinical features, laparotomy is the best way to preserve the lives of the mother and the fetus.1 However, oncologic procedures during pregnancy are an enormous challenge.
It is well known that, among non-pregnant women, radical surgical cyto-reduction and adjuvant chemotherapy are the standard of care for epithelial ovarian cancer.6 7 However, these tumors during pregnancy are rare, and due to their infrequency, a lot of questions regarding the treatment are pending. Thus, each case of epithelial ovarian cancer during pregnancy needs to be treated individually.6 7 According to some authors, due to increasing maternal age rates worldwide, an increase in the prevalence of cancers complicating pregnancies is soon expected.2 3 8 Considering the product well-being, a complete radical surgery for ovarian cancer during pregnancy in the primary surgery has not been previously reported.7
A multidisciplinary team working closely in the management of ovarian cancer during pregnancy is of paramount importance to obtain the best possible results7 9, like in the case presented in this study.
