Filter by: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).
This study aims to assess the effectiveness and safety of lenvatinib plus Chinese Herbal Medicine (CHM) for patients with uHCC in China.
Patients with biopsy-verified oropharyngeal squamous cell carcinoma or Human Papillomavirus (HPV)-positive unknown primary treated with transoral robotic surgery are included. Immediately post-operatively, freshly resected specimens are examined with ex vivo 3D ultrasound (US). Ex vivo 3D US will be used to match US slices of the specimen with corresponding histopathology slices. The US slices will be reviewed by a panel of head and neck surgeons blinded to histopathology. The primary aim is to explore perioperative ex vivo 3D US for oropharyngeal tumor detection, delineation from normal tissue, tumor size and volume, and margin assessment.
The study included 81 HCC patients, both male and female. Prior to being assessed for eligibility, each recruited patient with HCC received a comprehensive review of their medical history, physical status, and laboratory results. Every research participant take part in the experiment and provided written informed consent.
Triple-negative breast carcinoma is characterized by the absence of estrogen receptors, progesterone receptors, and HER2/neu receptors. Carbonic anhydrase IX (CA IX) is a tumor-associated cell surface glycoprotein that is involved in adaptation to hypoxia-induced acidosis and plays a role in cancer progression. This study aimed to investigate CA IX expression in TNBC and its relationship with treatment effect.
