Resumen
This study focuses on finding improved treatment strategies for advanced or metastatic synovial sarcoma, which is a rare and aggressive type of soft tissue sarcoma. The researchers tested a combination of two drugs, peposertib and doxorubicin, to see if they could work together to kill synovial sarcoma cells more efficiently. The experiments conducted in cultured cancer cells and mouse models of synovial sarcoma demonstrated that when these drugs were used together, they had a significantly stronger effect against cancer cells compared to using either drug alone. It is noteworthy that the combination could successfully overcome resistance to doxorubicin monotherapy in a patient-derived tumor model. This study also shed light on the underlying molecular mechanisms of this combination effect. Overall, the findings suggest that combining peposertib with doxorubicin could be a promising treatment option for synovial sarcoma patients in the future.
