Primary ovarian tumor undergoing surgical management during pregnancy.

The aim of this study was to evaluate the preoperative symptoms of patients with primary ovarian tumors undergoing surgery during pregnancy and non-pregnancy. We retrospectively analyzed the medical records of 71 pregnant patients who underwent surgery for primary ovarian tumors (pregnant) and 580 non-pregnant patients (non-pregnant) aged 15similar44 years old. In the non-pregnant group, 79.7% of the patients complained of abdominal pain at the first examination. However, in the pregnant group, 62.0% of the patients reported no symptoms and 31.0% of them reported abdominal pain (p<0.05). There were no significant differences in the percentage of ovarian malignancies between the two groups (8.5% vs. 6.6%). However, the incidence of the advanced stage of greater-than-or-equal Ic in ovarian malignancies in the non-pregnant group was 42.1%, while it was 0% (p<0.05) in the pregnant group. Ovarian tumors including ovarian malignancies were significantly more frequently diagnosed with no symptoms in the pregnant group than in the non-pregnant group.
