My research focuses on postoperative pain and functional outcomes in children with extremity soft tissue sarcomas (eSTS). These tumors account for a substantial part of pediatric soft tissue sarcomas and are increasingly treated with limb-sparing surgery (LSS). While LSS reduces the need for amputation, it can still lead to persistent pain and functional loss, especially when critical structures such as nerves, bones, or arteries are affected. The goal of my research is to better understand the prevalence and risk factors of postoperative and neuropathic pain, and to evaluate long-term functional outcomes to guide surgical strategies that optimize both survival and quality of life.
