Comorbid Thrombosis As an Adverse Prognostic Factor in Patients with Ovarian Clear Cell Carcinoma Regardless of Staging

Patients with ovarian clear cell carcinoma (OCCC) often present with thrombosis. While cancer patients with concomitant thrombosis were generally reported to have worse prognoses than those without, the association between thrombosis and prognosis has not been elucidated in OCCC. This study aimed to determine how the co-occurrence of thrombosis affects OCCC prognoses.
