简要总结
This is a multicenter, prospective, randomized, open-label Phase III clinical trial (RESCUE study) evaluating the efficacy of secondary cytoreductive surgery (SCS) in patients with platinum-sensitive recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who have shown a favorable response to 3-4 cycles of platinum-based neoadjuvant chemotherapy and are assessed as highly likely to achieve complete tumor resection based on selection models. Eligible patients will be randomly assigned to either the experimental arm, receiving SCS followed by chemotherapy (with or without maintenance), or the active comparator arm, receiving chemotherapy only (with or without maintenance), with the primary objective being to compare the Progression-Free Survival (PFS) between the two groups to determine the additional clinical benefit of SCS in this carefully selected patient population.
详细描述
The RESCUE study is a major clinical trial focused on improving treatment for women battling recurrent ovarian, fallopian tube, or primary peritoneal cancer. These cancers, which often return after initial treatment, are known to be aggressive. The challenge for doctors is deciding when and if a second major surgery, known as secondary cytoreductive surgery (SCS), will truly benefit the patient.
The Study's Focus: When is Surgery Best?
Currently, when the cancer returns, patients receive chemotherapy. The key question is whether adding a challenging surgery (SCS) to the chemotherapy offers better survival chances than chemotherapy alone. Past studies have suggested that SCS is only helpful if the surgeon can remove all visible signs of cancer.
The RESCUE study addresses this by using a modern, personalized approach:
Selection: The study enrolls patients whose cancer is platinum-sensitive (meaning it responded well to the initial platinum-based chemotherapy).

入选标准
- •First recurrence of platinum-sensitive, invasive epithelial ovarian, fallopian tube, or primary peritoneal cancer, regardless of initial stage.
- •A progression-free interval of at least 6 months after the end of the last platinum-containing regimen.
- •Demonstrated response during neoadjuvant chemotherapy after recurrence (Complete Response/Partial Response/Stable Disease according to RECIST 1.1 or GCIG CA-125 response, which is a ≥50% reduction in pre-treatment CA-125 level sustained for ≥28 days).
- •Women aged 19 years or older.
- •The tumor is judged to be completely resectable by surgery (R0) based on the judgment of an experienced surgeon
- •Patients who provide signed and written informed consent and consent to data transfer and processing.
排除标准
- •Patients without recurrence
- •Patients with non-epithelial tumors or borderline tumors.
- •Patients with second, third, or subsequent recurrence.
- •Patients with a secondary malignancy treated with laparotomy and other neoplasms, where the treatment is expected to interfere with the treatment of recurrent ovarian cancer or significantly affect prognosis.
- •Patients with platinum-refractory tumors (i.e., progression during chemotherapy or recurrence within 6 months after the end of the previous first platinum-containing regimen).
- •Cases where only palliative surgery is planned.
- •Radiological signs suggestive of metastasis that are considered completely unresectable.
- •Any comorbidity that precludes surgery and/or chemotherapy (e.g., poor general condition, severe infection, conditions that may cause severe bleeding, severe renal disease, etc.).
- •Any medical history that may cause excessive surgical risk pre- or post-operatively.
- •Medications being taken that pose a significant surgical risk (e.g., oral anticoagulants, bleeding risk due to bevacizumab).
- •Absence of evaluable archived tumor tissue.
