Liệu pháp kháng androgen thúc đẩy sự lây lan khối u xương ở ung thư tuyến tiền liệt giai đoạn cuối
Liệu pháp kháng androgen thường được sử dụng để điều trị cho bệnh nhân ung thư tuyến tiền liệt giai đoạn cuối, bệnh đã di căn vào xương.

Tuy nhiên, nghiên cứu mới cho thấy điều trị kháng androgen thực sự có thể tạo điều kiện cho các tế bào ung thư tuyến tiền liệt thích nghi và phát triển trong mô hình vi môi trường khối u xương, được phát triển bởi các nhà khoa học y sinh QUT do Tiến sĩ Nathalie Bock đứng đầu.

Phát triển các mô hình mô giống xương thu nhỏ 3D trong đó các giàn mô phỏng sinh học in 3D được cấy các tế bào xương và tế bào khối u có nguồn gốc từ bệnh nhân để sử dụng làm công cụ kiểm tra thuốc lâm sàng và tiền lâm sàng.

Nhóm nghiên cứu đã giả thuyết rằng liệu pháp kháng androgen truyền thống có tác dụng hạn chế trong môi trường vi mô của khối u xương ở ung thư tuyến tiền liệt. Phát hiện được công bố trên tạp chí Science Advances.

Nhóm nghiên cứu đã kiểm tra sinh học vi môi trường của khối u xương để đánh giá tác động của hai liệu pháp kháng androgen được sử dụng thường xuyên trên lâm sàng - enzalutamide và bicalutamide - lên các tế bào khối u.

Kết quả quan trọng của nghiên cứu là cần phải nâng cấp nền tảng mô hình vi môi trường khối u xương và cung cấp nó cho các nhóm nghiên cứu khác.

Trong tương lai, Tiến sĩ Bock sẽ sử dụng mô hình của mình với các tế bào có nguồn gốc từ bệnh nhân được phẫu thuật cắt tuyến tiền liệt, để nó có thể được sử dụng như một công cụ chẩn đoán tiền lâm sàng và thử nghiệm thuốc được cá nhân hóa.
