Brief summary: Evaluating the efficacy and safety of liposomal doxorubicin hydrochloride and apatinib in combination with camrelizumab for the first-line treatment of advanced/unresectable dedifferentiated liposarcoma

Detailed description: Based on the clinical benefits provided by doxorubicin liposome, apatinib and camrelizumab treatment in STS, this study intends to explore the efficacy and safety of doxorubicin liposome hydrochloride and apatinib combined with camrelizumab in the first-line treatment of advanced/unresectable dedifferentiated liposarcoma with the aim of providing a better therapeutic option for the clinic.
