Abstract | Ovarian cancer (OVCA) is the most lethal gynecological cancer, due mainly to late diagnosis, recurrence and chemoresistance. Although combined cytoreductive surgery and chemotherapy is a successful treatment modality initially, chemoresistance remains a major hurdle for long term therapeutic success. OVCA is considered a cold tumor and has poor immune cell infiltration, rendering immunotherapy ineffective to date. In this lecture, Professor Ben TSANG will elaborate on the role of plasma gelsolin (pGSN), a calcium-dependent actin-binding protein, in the molecular and cellular basis of chemoresistance in OVCA. Specifically, pGSN secretion is involved in exosome-mediated signaling in the ovarian tumor microenvironment, resulting in subtype-specific T cell anergy, apoptosis and chemoresistance. The clinical significance of his studies is pGSN could serve as a new biomarker for diagnosis of stage 1 cancer, in the prognostication in residual disease and a possible target for immunomodulation in chemoresistant OVCA patients |
