Abstract:
Objective: To evaluate the effect and safety of molecular targeted therapy of apatinib mesylate combined with multiple antigen stimulatiing cellular therapy in treatment of osteosarcoma and soft tissue sarcoma. Methods:Six patients with sarcoma were collected by the failure of surgery, radiation and chemotherapy treatment or refusal surgery, radiation and chemotherapy, and at least one month from the last treatment of surgery, radiation and chemotherapy. All of the patients at least received three cycle MASCTTM . From Day 1,everyone were given Apatinib 500 mg,po,qd ,until the disease progression. To measure the patient’s quality of life depending on EORTC QLQ-C30,meanwhile,detecting the cellular immunity function and circulating tumor cells(CTCs) of patients before treatment and one month after 3 cycle MASCTTM . At last, monitoring the cellular immune responses by the Enzyme-linked immuno spot ( ELISPOT) assay. Results: All of the four patients completed the treatment of 3 cycle MASCTTM . Only one patient reduced apatinib from 500 mg to 250 mg because of palmar-plantar erythrodyses-thesia. The response rates of the four patients received MASCTTM and apatinib mesylate after treatment were 1 for complete response (CR),3 for partial response (PR). The life quality and cellular immunity function were improved in all of the patients. ELISPOT assay suggested that the majority of antigen peptides could induce specific cytotoxic T lymphocytes( CTLs) response. The Progression-Free-Survival ( PFS) of four patients received MASCTTM and apatinib mesylate was 7,6,9 and 4 months ,while the response rates of the two patients received apatinib mesylate were 1 for ( Stable disease) SD,one for ( Progression disease) PD. And PFS of the two patients were one month and two months. Conclusion:Combination of MASCTTM and apatinib mesylate is safe,effective and were good prospects for application.
