Filter by:Radiation therapy has become the preferred treatment for nasopharyngeal cancer due to the sensitivity of nasopharyngeal carcinoma to radiation. However, even with the use of intensity-modulated radiation therapy (IMRT), radiation-induced temporal lobe injury (RTLI) can be a severe complication. Patients with RTLI may experience long-term memory loss, personality changes, physical dysfunctions, and other symptoms, which seriously impair their quality of life and long-term prognosis. Currently, the diagnosis of RTLI primarily relies on clinical symptoms and imaging examinations such as computed tomography (CT) and conventional MRI. However, these methods only enable the diagnosis of RTLI at a late stage when it is irreversible and cannot be effectively treated. Therefore, the early identification or individualized prediction of RTLI after IMRT holds exceptional importance for improving the quality of life in nasopharyngeal carcinoma patients. The exact mechanism of RTLI remains unclear. Many clinical covariates have been proven to be associated with RTLI in NPC patients, including stage, age, and dosimetric parameters. In addition, it was reported that each patient's temporal lobe exhibits unique genetic susceptibility to radiation exposure. In this study, we aim to predict the occurrence of RTLI by analyzing clinical factors and heterogeneity of temporal lobe tissue prior to irradiation. Finally, we want to construct and validate a prediction model for RLTI, which can support clinician decision-making in developing individualized treatment plans and providing preventive measures.
The oncologic benefit of lateral neck dissection (LND) during index operation for sporadic medullary thyroid carcinoma (MTC) basing on basal calcitonin (bCT) levels has been questioned due to the potential post-operative complications. This study aims to evaluate desmoplastic reaction (DSR), as predictor of nodal metastases, for definition of surgical strategy. Data from pathological report of MTC after operations between 1997 and 2022 were collected. The primary endpoint of the study was evaluating the risk factors for nodal metastases. The secondary endpoints analyzed the correlations between DSR and nodal metastases and the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of DSR for nodal metastases.
The goal of this multicenter retrospective cohort study is to evaluate the impact of different pathological regression types on survival and recurrence patterns, with a particular focus on ypT0N+ patients in patients with esophageal squamous cell carcinoma. The main questions it aims to answer are the survival and recurrence patterns among the different pathological regression types in patients with esophageal squamous cell carcinoma after neoadjuvant chemoradiotherapy.
Retrospective analysis of the presence and maturity of tertiary lymphoid structures in pathological sections of patients with esophageal squamous cell carcinoma after surgical treatment. Pay attention to the overall survival and disease free survival of these esophageal squamous cell carcinoma patients.
The IELN basin could represent a primary LN relay for systemic metastatic dissemination in patients with OPM. This newly described lymphatic pathway of metastatic dissemination of OPM may be involved in certain presentations of peritoneal dissemination. The presence of invaded IELN may represent a new biomarker predictive of the pattern of progression of OPM and a related risk for systemic dissemination.
The goal of this observational study is to investigate the effect of non-selective beta-blocker (NSBB) on the recurrence of hepatocellular carcinoma (HCC) following liver transplantation in patients who underwent liver transplantation (LT) for treating hepatocellular carcinoma. The main question[s] it aims to answer are: - Is the usage of non-selective beta-blocker associated with decreased recurrence of hepatocellular carcinoma following liver transplantation? - Is the usage of non-selective beta-blocker associated with all-cause mortality following liver transplantation? Researchers will compare the NSBB group, including patients who received non-selective beta-blocker therapy for at least 30 consecutive days within 3 months prior to liver transplantation more than 30 days prior, with the control group to to see if non-selective beta-blocker treatment is associated with decreased recurrence of hepatocellular carcinoma following liver transplantation.
Most hepatocellular carcinoma (HCC) are found in the intermediate or advanced stage. The patients lose the opportunity of curative surgical resection. In clinical practice, unresectable HCC is often encountered with large tumor lesions and insufficient remaining liver volume. It is expected that the benefit of direct surgical resection will not exceed that of non-surgical treatment if the tumor is limited in scope but with unclear boundaries, surrounding small foci, or adjacent to important vascular structures, or combined with secondary or higher portal vein tumor thrombus. These patients account for a significant proportion of unresectable HCC, but have the potential for surgical resection. If the investigators can make full use of the existing HCC treatment, the patients hope to obtain radical surgical resection opportunities and better long-term survival after tumor shrinkage and tumor necrosis boundary becomes clear. Transcatheter arterial chemoembolization (TACE) has been the standard arterial treatment for advanced HCC. Donafenib is a multikinase inhibitor that is the first-line treatment for hepatocellular carcinoma. Tislelizumab is an immune checkpoint inhibitor and a first-line treatment for HCC. This study investigated the efficacy and safety of TACE combined with donafenib and tislelizumab in the treatment of unresectable HCC.
Systemic therapy is the primary option for managing advanced hepatocellular carcinoma (HCC). The combination of atezolizumab and bevacizumab (A+B) has emerged as the first-choice treatment for advanced HCC(IM brave 150). The ORIENT-32 study, also reported an ORR of 24% for sintilimab plus a bevacizumab biosimilar (S+B) versus 8% for sorafenib, with significantly longer OS and PFS. Based on those therapeutic advantages over sorafenib, both the A+B and S+B regimens were approved as first-line treatment options for advanced HCC in China. These two trials had very similar designs but included different target populations. Our previous studies have demonstrated that a novel treatment approach combining transarterial chemoembolization (TACE) with hepatic arterial infusion chemotherapy (HAIC) has high efficacy in patients with potentially resectable HCC or portal vein tumor thrombus. However, it remains unknown whether combining immune checkpoint inhibitors and macromolecular VEGF-targeted therapy with transvascular local interventions could improve patient prognosis in uHCC.
This study is a multi-center, non-interventional study. Clinicopathologic, treatment , outcome and efficacy data will be collected from medical records in metastatic esophageal squamous cell carcinoma (ESCC) patients.
Patients with liver metastasis from esophagus squamous (ESC) are usually offered systemic therapy. However, for those with predominant liver disease or failure of system therapy, local liver management becomes an option. This prospective single center study aimed to evaluate the efficacy and adverse events of hepatic arterial infusion chemotherapy (HAIC) using percutaneous catheter placement techniques for liver metastases from esophagus squamous (ESC).
