Surgical Resection

Despite being generally benign tumors, meningiomas are associated with an increased risk for thrombembolic complications after surgical resection. The molecular mechanisms underlying this circumstance are still unknown. In this prospective observational trial, the investigators aim to evaluate the changes in coagulation and platelet function caused by tumor resection. Blood samples are obtained by patients undergoing meningioma resection before and immediately after resection to detect said changes. As a control cohort, blood samples are obtained from patients undergoing resection for glioma.

This is a clinical trial from Eastern Cooperative Thoracic Oncology Project (ECTOP), numbered as ECTOP-1023. This study aims to explore the safety and efficacy of primary lesion resection in the treatment of M1a stage lung cancer with pleural dissemination found during surgery, and to more accurately evaluate whether primary lesion resection can improve the OS and quality of life of the corresponding patients.

The purpose of this study is to evaluate the efficacy of preoperative 5-ALA oral administration and subsequently intraoperative tumor bed phototherapy with red light laser, as an adjuvant therapy on the 3 years rate of local tumor recurrence in patients with desmoid tumors. To evaluate the Safety of 5-ALA administration. 5 years local recurrence rate.
