Clinical trials

Hepatocellular carcinoma (HCC) is one of the most common types of primary liver cancer worldwide, characterized by complex and variable disease progression and significant treatment challenges. 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.

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. In this study, we will collect more than 400 patients who underwent thyroidectomy in 2025 and underwent carbon nanoparticle injections at different time points and analyzed their intraoperative and postoperative conditions as a basis for analyzing the difference in patient benefits between preoperative and intraoperative carbon nanoparticle injections and to provide data to support the clinical use of carbon nanoparticles.

As a major disease with high incidence and mortality rate, lung cancer seriously threatens the health of our people and causes a huge burden of disease. In recent years, with the widespread use of immune checkpoint inhibitors (ICIs), great progress has been made in the treatment of lung cancer, which has brought significant survival benefits to patients. Although ICI has greatly improved the prognosis of lung cancer patients, due to the complexity of the mechanism of action of ICI and the heterogeneity within the tumor, the benefit population of treatment is relatively limited, and some patients are still at risk of primary drug resistance and tumor hyperprogression.In this study, we aimed to compare the differences in the efficacy and adverse reactions of immunotherapy in patients with advanced non-small cell lung cancer at high and low altitudes, and to find out the relevant factors from multiple omics such as imaging, pathology, and genetics, so as to solve the problem of immunotherapy resistance

Clinical data, fresh feces and intestinal mucosal tissues of patients with diarrheal IBS were collected. High performance liquid chromatography, immunohistochemistry and immunofluorescence were used to study the amino acid levels in feces of patients with IBS, the expression of taste receptors in intestinal mucosa, and the correlation between symptoms of abdominal pain and diarrhea and the expression of taste receptors, so as to obtain the conclusion that "intestinal amino acid perception abnormalities exist in patients with IBS. And correlated with clinical symptoms."

The objective of this research is to investigate the clinical outcomes of modified surgical techniques such as omitting the cervical linea alba suture in transthoracic endoscopic thyroidectomy. Furthermore, the study requires the collection of normal thyroid tissues, benign and malignant thyroid tumors, and lymph nodes to further clarify the mechanisms associated with the initiation, progression, metastasis, and recurrence of thyroid cancer.

This prospective, single-arm trial explores the efficacy of Adibelimab monoclonal antibody combined with Famitinib and chemotherapy in treating locally advanced or metastatic NSCLC patients with negative driver genes who have progressed after PD-1 monoclonal antibody and chemotherapy treatment. The study focuses on assessing progression-free survival (PFS) in 40 participants. Key objectives include evaluating PFS and understanding the progression patterns post-first-line immunotherapy, with an interest in whether switching from PD-1 to PD-L1 inhibitors can overcome immune resistance.

The incidence of papillary thyroid cancer (PTC) has been on the rise in recent years, and 20%-50% of PTC patients will have lymph node metastasis. Lymph node involvement in PTC patients is usually related to the recurrence of PTC after surgery, and 30% of patients recur without lymph node dissection, with the risk of central cervical lymph node metastasis being the greatest, so it seems to be a good choice to perform lymph node dissection on patients after thyroidectomy, but in fact, there are controversies at home and abroad as to whether to perform lymph node dissection or not. The 2021 Chinese Society of Clinical Oncology (CSCO) guidelines for the diagnosis and treatment of differentiated thyroid cancer state that prophylactic central lymph node dissection (PCND) may increase the incidence of postoperative complications, but due to the high metastatic rate of PTC and the ability of PCND to effectively prevent recurrence and reoperation, countries in the East Asian region perform prophylactic lymph node dissection on almost all patients with PTC. However, for more countries in Europe and the United States, performing PCND has become a non-essential, individualized option. The aim of this study is to collect multifactorial data from more than 1,000 patients who have undergone previous thyroidectomy from 2021 to 2023, and to develop a novel scoring scale that can be used to individualize patients' scores based on a variety of factors prior to surgery, so that patients can be more accurately predicted to have lymph node metastasis and need prophylactic lymph node dissection prior to surgery, and patients who do not need dissection can avoid surgery. For patients who do not need lymph node dissection, complications caused by surgery can be avoided, while for patients who do have lymph node metastasis, recurrence of their cancer can be prevented. This will change the status quo of not being able to accurately determine the actual situation through simple preoperative examination or performing prophylactic lymph node dissection for all PTC patients.

This study collect the relevant data of local residents over 20 years old in 11 regions of Shaanxi Province, The basic information of the subjects was collected by filling in the questionnaire, and serum helicobacter pylori antibody detection was completed at the same time. The expert group determined the high-risk population of gastric cancer after comprehensive evaluation. All the high-risk population of gastric cancer without contraindications underwent electronic gastroscopy in the designated hospital after signing the informed consent. By collecting and analyzing data, early gastric cancer screening was completed and a new gastric cancer risk assessment model was established to evaluate the prevalence of dyspepsia, gastroesophageal reflux disease and precancerous lesions in the natural population of Shaanxi Province, as well as helicobacter pylori infection, radical treatment and recurrence rate.
