Among HCC patients, tumor budding (TB) is associated with a high risk of postoperative recurrence, significantly impacting patient prognosis. Even in the current HCC pathological diagnosis \"gold standard\" of MVI-negative patients, TB retains excellent prognostic predictive value. TB cells reside within the peritumoral stroma, where dense collagen fibers restrict the efficacy of therapeutic agents including chemotherapy, immunotherapy, and targeted therapies, making it difficult for single-agent treatments to effectively eliminate TB. Therefore, specific treatment strategies should be considered for TB-positive patients to improve survival outcomes and reduce the risk of tumor recurrence. To address this clinical challenge, this study aims to clarify the prognostic impact of combining collagen degradation therapy with targeted therapy in TB-positive HCC patients. Through a single-arm trial (postoperative targeted therapy + collagen degradation therapy), investigators explore the clinical efficacy and prognostic indicators of this combination approach, seeking the optimal treatment strategy for TB-positive HCC patients. Collagen degradation therapy facilitates drug delivery to tumor-bottle lesions by degrading collagen barriers, while targeted therapy specifically intervenes against cancer cells. Their combination holds promise for synergistic effects and enhanced therapeutic outcomes. This study aims to preliminarily assess the impact of this dual approach on prognosis, providing evidence for personalized treatment strategies. The findings of this research hold promise for delivering new breakthroughs in the treatment of TB-positive HCC patients, improving their quality of life and survival rates, and providing robust support for future clinical practice.",[26],"Carcinoma, Hepatocellular","NOT_YET_RECRUITING","2025-09-10",{"date":30,"type":31},"2025-09-16","ACTUAL",{"date":33,"type":20},"2025-10-01",{"date":35,"type":20},"2029-12-31",{"name":37,"class":38},"Second Affiliated Hospital of Xi'an Jiaotong University","OTHER",{"id":40,"slug":41,"hasResults":11,"nctId":42,"briefTitle":43,"officialTitle":44,"acronym":4,"eligibilityCriteria":45,"healthyVolunteers":11,"sex":16,"minAge":46,"maxAge":47,"enrollmentInfo":48,"targetDuration":4,"studyType":21,"phases":50,"briefSummary":52,"conditions":53,"keywords":55,"overallStatus":59,"whyStopped":4,"lastUpdateSubmitDate":60,"lastUpdatePostDateStruct":61,"startDateStruct":63,"completionDateStruct":65,"leadSponsor":67,"locationsCount":68},"100576877","phase-3-a-clinical-study-on-the-benefits-of-carbon-nanoparticles-injection-time-in-patients-with-thyroid-cancer-100576877","NCT06791005","A Clinical Study on the Benefits of Carbon Nanoparticles Injection Time in Patients With Thyroid Cancer.","A Comparative Study of Preoperative and Intraoperative Carbon Nanoparticles Injection in Patients Undergoing Thyroid Cancer Surgery","Inclusion Criteria:\n\n* Preoperative pathological assessment indicated the presence of thyroid cancer with a maximum diameter of less than 4 cm.\n* Postoperative pathological evaluation confirmed bilateral thyroid cancer or lateral lymph node metastasis.\n* Vocal cord examination conducted one week prior to surgery revealed no abnormalities.\n* The patient had no history of prior thyroid surgery and required a total thyroidectomy.\n* Blood pressure was stably controlled.\n* The patient regained consciousness and was able to communicate normally.\n\nExclusion Criteria:\n\n* Prior to enrollment, the patient had received radiotherapy, chemotherapy, or isotope therapy.\n* A documented history of thyroid surgery.\n* Age under 16 years.\n* Known allergies to the medications under investigation or an inability to tolerate surgical intervention.\n* Presence of a retrosternal thyroid tumor.\n* Tumor invasion of the parathyroid glands and\u002For the recurrent laryngeal nerve during surgical procedures.\n* Postoperative pathology suggestive of medullary carcinoma or undifferentiated carcinoma.\n* Development of a postoperative tracheal fistula.","16 Years","80 Years",{"count":49,"type":20},400,[51],"PHASE3","The detection rate of thyroid cancer (PTC) has increased rapidly in recent years. Except undifferentiated cancer, surgery is still one of the most important treatments for all types of thyroid cancer, and there is a consensus to use the lobes of the gland as the minimum extent of resection. In the meantime, a basic consensus has been reached that central zone lymph node (VI) dissection is the minimum extent of lymph node dissection. In clinical practice, neck surgery and lumpectomy are mostly performed. Hypoparathyroidism and recurrent laryngeal nerve injury are the most common complications of radical surgery for thyroid cancer, both in open surgery and the luminal approach. Once these complications occur, they have a serious impact on the quality of life of patients in the postoperative period. A number of contrast agents are now being used to help minimize complications. Carbon nanoparticles are an effective and non-harmful negative developer, and many studies have confirmed that carbon nanoparticles can be used to identify parathyroid glands in thyroid surgery. Intraoperative injection of nanocarbon is effective in increasing the quality of intraoperative parathyroid detection and lymph node clearance and reducing adverse effects, such as postoperative hypokalemia.However, there is no complete clinical guideline for preoperative intraglandular injection of carbon nanoparticles, and there is no standardized dosage for appropriate injection time, injection dose, and injection method. At the same time, there is still the problem of carbon nanoparticle leakage. At our medical center, we have found that preoperative injection of carbon nanoparticles via ultrasound-guided fine needle puncture may yield better results by reducing CNS exudation in the surgical area.
