Institutions Interested in Joining ECOG

Membership in ECOG is open to institutions such as universities, medical centers, community hospitals, cancer centers, clinics, and physician practices that treat oncology patients and have an interest in participating in cancer clinical trials. Most institutions begin their association with ECOG either as an affiliate of a main member institution or as a CCOP component (in the NCI Community Clinical Oncology Program). Affiliate institutions are required to be sponsored by a main member institution and enter 6 patients per year with at least 3 of the accruals coming from therapeutic studies. Main member institutions are required to enter 50 patients per year and contribute significantly to the scientific and administrative leadership of the Group. An institution may not be a member of more than one NCI multi-modality adult cooperative group (e.g., SWOG, CALGB), unless otherwise discussed with ECOG, although they may be members of other specialty groups (e.g., RTOG, GOG, NSABP).
