Brief Summary

To investigate the safety and efficacy of preoperative moderately fractionated IMRT and concurrent Fluzoparib Hydrochloride for primary truncal or extremity soft tissue sarcoma.

Detailed Description

To investigate the safety and efficacy of preoperative moderately fractionated IMRT and concurrent Fluzoparib Hydrochloride for primary truncal or extremity soft tissue sarcoma; To investigate the Quality of life and extremity function post-combination treatment; To study the mechanism of radio-sensitizing effects of Fluzoparib Hydrochloride for primary truncal or extremity soft tissue sarcoma; To assess the relationship between the MRI imaging, pathological findings and local control.

GroupInterventionDescription
Preoperative moderately fractionated RT with FluzoparibPreoperative moderately fractionated radiotherapayPatients will receive preoperative moderately fractionated radiotherapy (RT)(43.5Gy/15fr). One week before RT onset, during radiotherapy and 5 weeks post-RT, patients also take oral Fluzoparib (100mg, BID, five days per week). Wide resection surgery would be done around 6 -10 weeks post-RT.
Preoperative moderately fractionated RT without FluzoparibPreoperative moderately fractionated radiotherapayPatients will receive preoperative moderately fractionated radiotherapy (RT)(43.5Gy/15fr). No radio-sensitizing drugs was given. Wide resection surgery would be done around 6 -10 weeks post-RT.
