The GOG was founded in 1970[1] by a group of gynecologic surgeons from 11 institutions.
The formation of the GOG was the result of the recognition of the need for collaborative research in the gynecologic malignancies.
Before the GOG was founded, most clinical trials were small studies from single institutions or case reports and lacked the statistical power to convince physicians around the world to adopt innovative treatment strategies.
The GOG has now grown to include over 50 research centers and has over 160 affiliated institutions.
Over 3,000 patients are treated each year on GOG protocols.
