Clinicopathological analysis of giant ovarian tumors

Objective

This study aims to analyze giant ovarian tumors' clinical and pathological characteristics.

Material and Methods

This was an analytical observational study. Medical records of all patients with giant ovarian tumors who underwent surgery between January 2020 and June 2022 at Dr. Soetomo Academic Hospital, Surabaya, Indonesia, were analyzed.

Results

We analyzed 63 patients with ovarian tumors measuring > 20 cm who underwent surgery at Dr. Soetomo Academic Hospital, Surabaya, Indonesia. The mean tumor size was 25.9 cm (largest size was 41 cm). There was no significant difference in tumor size between benign and malignant giant ovarian tumors (p = 0.261). Based on histopathological results, 66.67 % of giant ovarian tumors were malignant, 26.98 % were benign, and 6.35 % were borderline. Among the malignant tumors, the epithelial type accounted for 69 % of cases. Most giant ovarian tumors originated in the left adnexa (68.25 %). There was no significant difference in patient age (p = 0.511), tumor size (p = 0.168), malignancy (p = 0.303), and histopathological type (p = 0.232) regardless of adnexal side. CA125 levels did not differ significantly between malignant and benign giant ovarian tumors (p = 0.604). There was no correlation between malignant ovarian tumor size and CA125 levels, while there was a significant difference between CA125 levels and the adnexal side (p = 0.010).

Conclusions

Most giant ovarian tumors were malignant, diagnosed at an early stage, and predominantly epithelial type. CA125 levels did not correlate with the size of malignant ovarian tumors. Most giant ovarian tumors originate in the left adnexa.
