Immunobiology and immunotherapy of gestational trophoblastic disease

Gestational trophoblastic diseases are a heterogeneous group of pregnancy related tumors that show extensive metastatic spread but are readily responsive to chemotherapy. This one of a kind treatability of gestational trophoblastic tumors may to some extent be inferable from a host immunologic reaction to the paternal antigens that are expressed on the trophoblastic cells. In this review, we evaluate the current cognizance of immunobiology of gestational trophoblastic diseases and also establish the immunologic behaviour of gestational trophoblastic diseases which should be researched further in order to gain a better understanding of the aetiology of these neoplasias. This will further help structuring immunotherapeutic methodologies for their treatment.
