Abstract

OBJECTIVE: To compare the ultrasound characteristics of patients with synchronous primary cancers of the endometrium and ovary vs those of patients with endometrial cancer with ovarian metastasis.

METHODS: This was a single-institution retrospective observational study of patients with a histological diagnosis of endometrial cancer and an ovarian malignant mass, who had undergone preoperative ultrasound examination at our unit. Based on the histological diagnosis, patients were classified into two groups: those with synchronous primary cancers of the endometrium and ovary (synchronous group) and patients with endometrial cancer with ovarian metastasis (metastasis group). We compared the ultrasound features of ovarian malignant masses and of endometrial cancers between the two groups. Student's t-test, Mann-Whitney U-test, χ2 test or Fisher's exact test were used for comparisons of variables between the two histological groups, as appropriate.

RESULTS: We identified 131 patients, of whom 51 had synchronous primary cancers of the endometrium and ovary (synchronous group) and 80 had endometrial cancer with ovarian metastasis (metastasis group). On ultrasound examination, ovarian masses in the synchronous group were more often multilocular-solid and less often bilateral than those in the metastasis group. With respect to the ultrasound features of the endometrial lesions, the median largest diameter was 29 (range, 11-118) mm in the synchronous group in comparison with 51.5 (range, 6-150) mm in the metastasis group (P < 0.0001). Endometrial lesions in the synchronous group presented more often with no myometrial infiltration and less often with a multiple-vessel pattern on color Doppler compared with the endometrial lesions in the metastasis group.

CONCLUSIONS: Synchronous primary cancers of the endometrium and ovary have significantly different sonomorphological patterns compared with endometrial cancer with ovarian metastasis. Ovarian masses in women with synchronous primary cancers of the endometrium and ovary appeared as unilateral multilocular-solid or solid masses, whereas ovarian masses in women with endometrial cancer with ovarian metastasis were mostly bilateral solid masses. The different sonomorphology of these two cancers may facilitate their preoperative identification, helping the surgeon to determine optimum management for the patient. Copyright © 2019 ISUOG.
