Background: Given the heterogeneity and high mortality associated with metastatic soft tissue sarcoma, this study aims to evaluate the therapeutic efficacy of combining 177 Lu-FAPI-46 with Pazopanib against this malignancy.
Methods: Patient-derived xenograft (PDX)-bearing mice were randomly divided into three groups: the control group, the 177 Lu-FAPI-46 monotherapy group, and the 177 Lu-FAPI-46 combined with Pazopanib therapy group. Therapeutic efficacy was regularly monitored.
Results: The microPET imaging showed a 0.84-fold decrease in the T/M ratio of 68Ga-FAPI-46 on day 7/8 post combination therapy, while the control group exhibited a 1.23-fold increase. Combination therapy significantly inhibited tumor proliferation, as evidenced by reduced Ki-67 and increased caspase 3 expressions. Notably, there was no significant body weight loss observed in any group.
Conclusion: This study successfully demonstrated the reduction in FAP expression and suppression of tumor volume in sarcoma PDX following the combination therapy of 177 Lu-FAPI-46 with Pazopanib.
