The aim is to establish 3D bioprinted patient-derived ovarian cancer models to predict therapy efficacy and reveal tumor heterogeneity.
Developed 3D bioprinted models using primary ovarian cancer cells and Gelatin Methacryloyl (GelMA).
Established 113 patient-derived models from a cohort of 79 ovarian cancer patients.
Conducted drug sensitivity testing with 15 different chemotherapeutic and targeted drugs.
Measured cell viability and calculated IC50 values for each drug in the models.
Performed a prospective observational cohort study with newly diagnosed stage III/IV patients.
3DP-OC models closely mirrored the paired tumor tissues in key molecular markers and Ki-67 levels.
Significantly prolonged progression-free survival in the sensitive group compared to resistant group (P < 0.05).
Observed interpatient heterogeneity in therapeutic responses, with disease progression rates differing between sensitive (16.7%) and resistant (52.9%) groups.
