Filter by:This is a multi-center, open-label, Phase 0 substudy designed to evaluate the ability of pembrolizumab, alone and in combination with MK-0482 or MK-4830, to elicit pharmacodynamic changes suggestive of antitumor immune activation within the native tumor microenvironment (TME) following intratumoral microdosing via the CIVO device in patients with surface accessible Head and Neck Squamous Cell Carcinoma (HNSCC) or Soft Tissue Sarcoma (STS) lesion(s) who are scheduled for tumor and/or regional node dissection as part of their standard treatment.
The study evaluated the protein expression levels of FK506-binding protein 12 (FKBP12) in hepatocellular carcinoma (HCC) and paracancerous tissues using immunohistochemistry (IHC). This study aimed to determine the role of FKBP12 in the outcome of liver transplantation recipients with HCC, especially those exceeding the Milan criteria. In addition, we explored how sirolimus administration affected LT recipients'prognosis depending on different FKBP12 expression, aiming to provide some advice for clinical sirolimus application after LT.
This is a prospective study to investigate the biomarkers in predicting treatment outcome and toxicity in hepatocellular carcinoma (HCC) patients receiving immune checkpoint inhibitors with or without stereotactic body radiotherapy (SBRT).
Rising thyroid carcinoma rates, with papillary thyroid carcinoma (PTC) as the main type (85-90% of cases), often show early cervical lymph node spread. This increases the risk of PTC patients for recurrence and death. A new study's multimodal model fuses preoperative US and cytology images to better predict lymph node metastasis, aiming to improve treatment plans, reduce unnecessary surgeries, and enhance patient outcomes.
Hepatectomy is the first option for the treatment of hepatocellular carcinoma(HCC) at CNLC Ib stage. HCC patients who undergo curative hepatectomy may experience varying remnant liver volumes and thus leads to different oncological outcomes.
Sporadic bilateral renal cell carcinoma (BRCC) is a rare situation of RCC. The treatment for BRCC is controversial and there is a lack of authoritative guidelines about the management of BRCC. The goal of this cohort study is to identify prognostic factors, construct predictive nomograms, and optimize management for sporadic BRCC patients. The main questions it aims to answer are: What are the factors influencing the prognosis of BRCC patients? What's the appropriate treatment for BRCC patients? Researchers will analysis the prognostic factors and compare the prognosis of BRCC patients receiving different treatments.
Nasopharyngeal carcinoma is one of the most common malignant tumors in China, with the progress of radiochemical comprehensive treatment, early stage The 5-year survival rate of nasopharyngeal cancer is more than 95%. However, due to the hidden site of nasopharyngeal carcinoma and the lack of obvious early clinical symptoms, more than 70% of the 87,000 newly diagnosed cases each year belong to the advanced stage of nasopharyngeal carcinoma, and the 5-year survival rate of advanced nasopharyngeal carcinoma is only about 70%. Therefore, early screening and diagnosis and early treatment are the key to improve the survival of patients with nasopharyngeal cancer. Selecting a sensitive and accurate biomarker for nasopharyngeal cancer and relying on a simple and feasible examination method for sampling detection will greatly improve the early diagnosis rate of nasopharyngeal cancer. DNA methylation is a form of chemical modification of DNA that can be done without altering the DNA sequence changes in genetic expression. The main role of DNA methylation is to regulate gene expression. Tumor suppressor genes play the functions of regulating cell differentiation, maturation and programmed death. However, if methylation of promoter region occurs, the expression of tumor suppressor genes is inhibited and the function is lost, resulting in cells remaining in the stage of low differentiation and proliferation, inhibition of apoptosis, formation of blood vessels by cluster cells, loss of cell adhesion, and formation of tumors. It can be seen that DNA methylation occurs in the early stage of tumor, and this biological feature makes it a strong application prospect in early tumor screening. There are many methods to detect DNA Methylation, among which methylation-specific PCR (MSP) can easily and quickly determine the methylation status of a specific gene, meeting the affordable, convenient, and easy to generalize characteristics required for screening tests. In combination with previous MSP experiments and previous reports, we found that the methylation levels of promoter fragments of H4C6, Septin9 and RASSF1A genes in nasopharyngeal carcinoma tissues were significantly higher than those in healthy human nasopharyngeal tissues. This suggests that methylation of these three genes may be used as biomarkers for early screening and diagnosis of nasopharyngeal carcinoma. Therefore, this study intends to detect the methylation status of H4C6, Septin9 and RASSF1A genes based on MSP method with simple operation and low cost. Using clinicopathological diagnosis as the gold standard, the value of this gene methylation index in early screening and early diagnosis of nasopharyngeal cancer was verified, providing a new detection index and method for improving the early diagnosis rate of nasopharyngeal cancer.
Background: Majority of liver transplantation (LT) recipients for hepatocellular carcinoma (HCC) were concomitant with liver cirrhosis, while few researches focusing on recipients without cirrhosis. Here we aim to investigate the prognosis of non-cirrhosis HCC recipients, expecting to provide theoretical basis for further improvement of these patients. Methods: This retrospective study analyze outcomes between adult HCC recipients arising in non-cirrhotic and cirrhotic liver from two national databases (CLTR and UNOS, January 2015 to December 2020). Based on important variables, 1:2 and 1:1 propensity score matching (PSM) were performed respectively.
To investigate the incidence, predictive markers, and survival impact of massive nasal bleeding in nasopharyngeal carcinoma (NPC) patients who received curative radiotherapy (RT) with/without chemotherapy. A total of 1327 patients with previously untreated, biopsy-proven NPC, and no distant metastasis were retrospective reviewed. Investigators analyzed the occurrence rates of massive nasal bleeding between different characteristics and tried to identify important predictive factors. Investigators compared overall survival between patients with and without massive nasal bleeding by Kaplan-Meier method.
A retrospective study of a single-center prospective database of patients who underwent curative CRS-HIPEC for peritoneal carcinomatosis (PC) of colo-rectal cancer (CRC), between September 2012 and July 2023 at Reims Hospital-University was conducted. Inclusion criteria were: patients older than 18 years with a performance status ≤ 2, who underwent complete (no macroscopic residual disease) CRS-HIPEC was performed. Exclusion criteria were the presence of an infectious disease prior to surgery, CRS without HIPEC, incomplete CRS and expressed refusal to participate in the study. During the month prior to surgery, patients underwent a thorough diagnostic workup, including chest and abdominopelvic computed tomography (CT) scans, complete haematological and biochemical tests, and cytobacteriological analysis of urine. Blood tests included leukocytes, neutrophils, lymphocytes, platelet count, albumin and CRP. Within one week before surgery, patients were examined by both the surgeon and the anaesthetist. Variables with a normal distribution are presented as mean-SD, while those with a non-normal distribution are presented as median and range. Categorical variables are presented as counts and percentages. Chi-Square or Fisher's exact test was used to compare qualitative variables. Linear regression analysis was used to assess any association between preoperative inflammatory biomarkers and patient comorbidities and disease characteristics. Preoperative levels of inflammatory biomarkers were compared between patients with no postoperative complication (POC) and patients with POC and major POC using the non-parametric Mann-Whitney U test. Optimal cut-off values for significant inflammatory biomarkers were determined using the Youden index. Receiver operating curves (ROC) were calculated to determine the area under the curve (AUC). Univariable and multivariable analyses including cut-off values of significant biomarkers were performed in a binary logistic regression analysis and expressed as odds ratios (OR). All tests were two-tailed and results were considered significant if the p-value was < 0.05. Statistical analyses were performed using R software (version 4.0.5).
