At present, the standard treatment of head and neck squamous cell carcinoma recommended by the National Comprehensive Cancer Network(NCCN) treatment guideline in the United States and the Chinese Society of Clinical Oncology(CSCO) treatment guideline in China is a comprehensive treatment model based on surgery, supplemented by radiotherapy, chemotherapy, immunization and targeted therapy. Neck lymph dissection is one of the most important surgical procedures for the treatment of head and neck squamous cell carcinoma. The injury of surgery and postoperative adjuvant radiotherapy leads to inadequate drainage of lymphatic system, leading to head and neck lymphedema.\n\nVascularized lymph node transplantation is successfully used in the treatment of upper and lower limb lymphedema, but has not been reported in the treatment of head and neck lymphedema.\n\nAt present, neck lymph dissection is the standard surgical protocol for head and neck squamous cell carcinoma, and there is no clear evidence that neck lymph dissection can be avoided. The dorsal thoracic artery flap can be used to make the flap of chimeric axillary lymph node, and can also be used as one of the vascularized lymph transplantation donor areas for the treatment of lymphedema without increasing the risk of upper limb lymphedema in the donor area.\n\nTherefore, the investigators propose: Can the function of the head and neck lymphatic system be reconstructed by transplanting normal lymph nodes from other parts of the body into the neck to form new lymphatic pathways at the same time of operation for head and neck squamous cell carcinoma? In our previous operation for head and neck squamous cell carcinoma, thoracic dorsal artery flap with partial axillary lymphoid tissue transplantation was used to repair head and neck defects. Retrospective analysis showed that the lymph node transplantation in the previous cases survived. Therefore, this project designed a prospective exploratory clinical study to clarify the activity and donor safety of cervical vascularized lymphatic transplantation, and further explore the effect of vascularized lymphatic tissue transplantation to rebuild the cervical lymphatic system in reducing the incidence of postoperative head and neck lymphedema, alleviating cervical fibrosis after radiotherapy and even improving the prognosis of patients.",[61,26,62,63],"Head and Neck Squamous Cell Carcinoma","Neck Lymph Dissection","Vascularized Lymph Node Transplantation",[65,61],"Vascularized lymph node transplantation","NOT_YET_RECRUITING","2025-02-03",{"date":69,"type":40},"2025-02-07",{"date":71,"type":20},"2025-03-20",{"date":73,"type":20},"2027-12",{"name":75,"class":47},"Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University",1,{"id":78,"slug":79,"hasResults":11,"nctId":80,"briefTitle":81,"officialTitle":82,"acronym":4,"eligibilityCriteria":83,"healthyVolunteers":11,"sex":84,"minAge":17,"maxAge":4,"enrollmentInfo":85,"targetDuration":4,"studyType":21,"phases":87,"briefSummary":88,"conditions":89,"keywords":96,"overallStatus":36,"whyStopped":4,"lastUpdateSubmitDate":102,"lastUpdatePostDateStruct":103,"startDateStruct":105,"completionDateStruct":107,"leadSponsor":109,"locationsCount":76},"100557041","the-robot-lva-study-robot-assisted-microsurgical-lymphaticovenous-anastomosis-in-breast-cancer-related-lymphedema-100557041","NCT06532955","The Robot-LVA Study: Robot-assisted Microsurgical Lymphaticovenous Anastomosis in Breast Cancer-related Lymphedema","Pilot Study on Robotic Assisted Microsurgical Lymphatico-venular Anastomosis","Inclusion Criteria:\n\n* Female gender;\n* Treated for primary early stage breast cancer;\n* Early stage lymphedema of the arm (stage 1 or 2 on ISL classification);\n* ELV \\> 10%;\n* Suffering from unilateral disease.\n\nExclusion Criteria:\n\n* Male gender;\n* Stage 3 lymphedema of the arm;\n* Receiving current breast cancer treatment;\n* Distant breast cancer metastases;\n* Current substance abuse;\n* History of marcaine or indocyanine green allergy;\n* Non-viable lymphatic system as determined by near infrared imaging;\n* Previous LVA (\\\u003C10 years) in the arm with lymphedema.","FEMALE",{"count":86,"type":20},60,[23],"This study assesses the performance of robot-assisted microsurgery.
