Официальное название

Secondary Cytoreduction Followed by Chemotherapy Versus Chemotherapy Alone in Relapsed Ovarian Cancer After PARPi Maintenance Treatment: a Multicenter, Open-label, Randomized, Phase 3 Trial

Обзор

This study aims to carry out a multi-center, randomized controlled study on patients with recurrent ovarian cancer after PARPi maintenance, to explore the clinicopathological and molecular characteristics of patients with recurrent ovarian cancer after PARPi maintenance, and to clarify whether patients with recurrent ovarian cancer after PARPi maintenance for more than 6 months are sensitive to platinum drugs, and the value of secondary tumor cell reduction in such treatment, In order to provide evidence-based medicine basis for the standardized treatment mode of recurrent ovarian cancer after PARPi maintenance treatment.

Вмешательства

• Процедура Secondary cytoreduction
  Open surgery is conducted by senior clinicians in gynecological oncology. Operation time，location and number of relapsed lesions, location and number of excised lesions, Whether achieved R0 or not, and other information are recorded.
• Препарат Chemotherapy
  chemotherapy

Первичные конечные точки

• progression free survival (PFS) [Срок оценки: 18-24 months]
