title: Primary ovarian tumor undergoing surgical management during pregnancy.
abstract: 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.
