The organoids from the biopsy showed a similar mucinous histology that was diffusely positive for AR and pan-cytokeratin. When grafted into mice, the tumor exhibited the identical histology as well as positivity for AR and pan-cytokeratin. The established organoid line exhibits a double time of 1 week.
MSK-PCa3 is derived from a patient who presented with metastatic prostate cancer to the pelvic lymph nodes with a diagnosis PSA of only 1.53 ng/dl. Biopsy showed adenocarcinoma with mucinous features that was positive for AR but negative for PSA. Despite a PSA response to <0.05 ng/dl, the patient progressed radiographically and a second biopsy was performed.
