This monthly Project ECHO series brings together international experts to advance best practices in the diagnosis, management, and research of gestational trophoblastic disease (GTD) through real-world cases, focused lectures, and interactive discussion. A global educational initiative developed collaboratively by the International Gynecologic Cancer Society (IGCS), the International Society of Gynecological Pathologists (ISGyP), and the International Society for the Study of Trophoblastic Diseases (ISSTD).

By bringing together the complementary expertise of IGCS, ISGyP and ISSTD, these monthly educational offerings will integrate clinical management, pathological diagnosis, surgical and medical decision-making, and emerging research. Learners will benefit from a truly international perspective, with insights drawn from diverse practice settings and patient populations, reinforcing the importance of collaboration across disciplines and borders.

ECHOs are held on the last Thursday of every month. Click here to register for future GTD ECHOs
