Abstract:
Background:
Ovarian cancer is a common gynecological malignant tumor in women. Most patients have reached the advanced stage when they visit the
hospital. In order to diagnose ovarian cancer at an early stage, treat it at an early stage, and improve the survival rate of patients, this study has used
the imaging computed tomography (CT) method to diagnose stage IA ovarian cancer.
Purpose:
The purpose of this work was to study CT features of stage IA ovarian cancer, and compare the borderline tumor and stage IC ovarian cancer at the
same time so as to improve the CT diagnosis of early ovarian cancer.
Methods:
We retrospectively collected clinical and CT data of patients with stage I ovarian cancer and borderline ovarian tumor admitted to Nantong Tumor
Hospital from 2013 to 2021. Altogether, 23 cases of patients (borderline ovarian tumor, 9 cases; stage IA ovarian cancer, 5 cases; stage IC ovarian
cancer, 9 cases) were involved. CT characteristics of these patients were analyzed in terms of the tumor diameter, cystic solid structure, solid
component, septation, enhancement, peritoneal thickening, ascites, and abdominal lymph nodes.
Results:
CT features of stage IA ovarian cancer included large tumor size (average diameter: 15 cm), cystic solid structure (4/5; 80%), septation (4/5; 80%),
and enhanced cystic wall, septum, or solid components of the tumor on contrast-enhanced CT (5/5; 100%), no peritoneal thickening (0/5; 0%), no
ascites (0/5; 0%), and no abdominal lymph node enlargement (0/5; 0%). The tumor structure did not differ significantly between stage IA and IC
ovarian cancers (p > 0.05), while intraperitoneal ascites did (χ2 = 0.031; p < 0.05). Stage IA and borderline ovarian tumors did not differ
significantly in ovarian tumor structure (p > 0.05).
Conclusion:
CT features of stage IA ovarian cancer included large tumor size, cystic solid structure, septation, and enhanced cystic wall and solid parts in the
tumors. No pelvic or abdominal metastasis was observed.
