Clinical Trial Summary

To compare patient outcomes following interval and delayed cytoreductive surgeries and no surgery (neoadjuvant chemotherapy alone) and international variations in access to cytoreductive surgeries in women with advanced stage ovarian cancer.

Description:

Standard of care in patients with advanced ovarian cancer is primary cytoreductive surgery followed by chemotherapy. Neoadjuvant chemotherapy and interval cytoreductive surgery is an alternative in selected patients. Most data exist with interval cytoreductive surgery following 3-4 cycles of chemotherapy, however, some patients experience a delay. So far, the impact of delayed cytoreductive surgery (following >5 cycles of chemotherapy) on patient outcomes is poorly defined. There is also a paucity of data in women who undergo no surgery (>5 cycles of chemotherapy alone) and factors influencing international discrepancies in access to cytoreductive surgery.
