Intensity Modulated Radiotherapy

To investigate the safety and efficacy of preoperative IMRT and concurrent Anlotinib 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 Anlotinib Hydrochloride and Penpulimab for primary truncal or extremity soft tissue sarcoma; To assess the relationship between the MRI imaging, pathological findings and local control.

This observational study aims to evaluate the efficacy and safety of intensity-modulated radiotherapy (IMRT) alone in patients with stage IB nasopharyngeal carcinoma (NPC) without high-risk features. The primary objective is to determine the therapeutic effectiveness of this approach

The goal of this clinical trial is to compare the survival and adverse reactions differences between endoscopic surgery and intensity modulated radiotherapy for patients with newly diagnosed stage Ⅰ nasopharyngeal carcinoma, aiming to verifying the efficacy and safety of endoscopic surgery for stage Ⅰ nasopharyngeal carcinoma.

To evaluate the long-term local control, survival rate, acute and late radiation related toxicities, quality of life after reducing high risk primary tumor clinical target volumes (CTVp1) in non-metastatic nasopharyngeal carcinoma treated with IMRT.
