Active clinical trials for "Carcinoma"

This is an external control, observational, retrospective study designed to compare clinical outcomes for pralsetinib compared with best available therapy for patients with RET-fusion positive advanced NSCLC.

Background: Upper tract urothelial carcinoma (UTUC) is a rare tumor associated with bladder cancer in up to 50% of cases. Its incidence is rising due to improved detection and bladder cancer survival. The diagnosis of UTUC is challenging because more than 35% of the standard biopsies can result inconclusive. The grading of UTUC cells, which delivers the most important data for the choice between a kidney-sparing surgery (KSS) and a radical treatment, is upgraded in 30% of radical nephroureterectomies. The follow-up of UTUC after KSS requires an invasive procedure as a diagnostic ureteroscopy for a minimum of 5 years, and urinary cytology has low diagnostic power. Objective: The aim of the study is to evaluate the accuracy (overall and stratified for grade) of a DNA methylation urine biomarker test (Bladder EpiCheckTM) in UTUC, and to compare it with current standard (urinary cytology). The secondary objective is to show its applicability in the specific clinical scenario of UTUC surveillance after kidney-sparing surgery and related cost-effectiveness. Design, Setting, and Participants: From February 2019 to February 2021, 80 consecutive patients candidates to ureteroscopy for suspicion of primary, recurrent or metachronous UTUC in one tertiary Referral Centers (Fundaciò Puigvert) giving written informed consent will be included in the study. Intervention: Bladder urine samples (> 10 ml) will be collected for cytology and for the methylation test before cystoscopy. Prior to semirigid and flexible ureteroscopy, urine specimens from the upper urinary tract will be obtained via a ureteral catheter.

The purpose of this study is to explore whether the imaging model based on RESOLVE-DWI sequence can exploiting the heterogeneity of nasopharyngeal carcinoma and indicate the prognosis, so as to provide intervention information for clinical decision-making. All patients were randomly divided into the training group and the validation group. Radiomics features extracted from T2-weighted, DWI, apparent diffusion coefficient (ADC), and contrast- enhanced T1-weighted were used to build a radiomics model. Patients'clinical variables were also obtained to build a clinical model. Model of training cohort was established using cross-validation for nasopharyngeal carcinoma prognosis by machine learning, including Logistics Regression, SVM, KNN, Decision Tree, Random Forest, XGBoost, and then, the model will be verified in the validation cohort. Area under the curve (AUC) of the Machine learning model was used as the main evaluation metric.

To evaluate the short-term efficacy of novel no-touch combined directional perfusion radiofrequency ablation in the treatment of small hepatocellular carcinoma with cirrhosis.

This project is a pilot study to interrogate the potential of LMS as a predictive tool for the selection of therapy for HCC patients. The reliability of LMS to predict patients' response following HCC therapy will leverage on an algorithm that is built from the pool of MRI scans from HCC patients pre- and post-treatment. In the study, MRI scans of 30 HCC and metastatic colorectal cancer (CM) patients (ratio of 4:1) will be analysed. CM cancer patients include patients whose cancers metastasized from colorectal cancer or primary liver cancer. These patients will either receive one of the treatment, surgical resection, Y90 or systemic therapy. A total of 4 MRI scans will be taken for each patient; the first MRI scan will be taken within a month before treatment initiation and the remaining MRI scans will be taken at the 1st, 3rd and 9th month post-initiation of treatment.

The primary goal of this study is to quantify the biomarkers of pre-radiation therapy(RT), during-RT, and post-RT serum samples from hepatocellular carcinoma (HCC) and esophageal cancer patients undergoing definitive or neoadjuvant RT, and to correlate them with tumor response, patterns of failure, survival outcome, and RT-related lung or liver toxicity. The secondary goal of this study is to set up the PLA platform in our institute for future biomarker test.

Objectives: Primary: 1. To assess the feasibility of using social networking groups to survey patients with rare cancers. Secondary:1. To elucidate the current means for diagnosis and treatment of women with small and large cell carcinomas of the cervix. 2. To evaluate anxiety regarding diagnosis, treatment, and recurrence among women with small and large cell carcinomas of the cervix.

The investigators propose a prospective, web-based database (developed within the framework of Quickbase, Intuit) which will allow an evaluation of the data for patients with a liver tumour who receive a liver transplant. Each site will continue to transplant according to their own criteria for inclusion on the waiting list. Each center will be responsible to enter a short list of data points at time of listing, transplant, and at 1 and 2 years post transplant. Data will be gathered prospectively through a web-based anaonymized database, and outcomes analyzed yearly X5 for tumour recurrence and patient survival.

Nasopharyngeal carcinoma (NPC) differs from other head and neck malignancies in terms of its epidemiology, pathology, and treatment outcome . It is endemic in China and is one of the major public health problems. Concurrent radiotherapy and chemotherapy is the primary treatment for patients with NPC. Despite such aggressive treatment, many patients with locally advanced NPC still develop locally recurrent disease. Since local control is directly related to patient morbidity and mortality in NPC, there is a strong need to identify methods to further improve treatment outcome for NPC. One strategy to improve local control is to escalate the dose of radiotherapy. This is because local control has been shown to be directly related to the radiotherapy dose. Several different techniques, including brachytherapy, stereotactic radiosurgery, and dose-painting intensity modulated radiotherapy (IMRT), have been used to increase radiotherapy dose. However, due to the large number of critical anatomic structures near the nasopharynx, dose-escalation in NPC can also lead to increased toxicities. One technique that has achieved dose-escalation with minimal increase in toxicity is simultaneous modulated accelerated radiation therapy (SMART). The main challenge for such treatment is to identify the appropriate tumor volume to receive the high-dose radiotherapy. Conventional dose-escalation is conducted using computed tomography (CT) to identify the gross tumor volume (GTV). However, recent progress with F-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in treatment planning allows more accurate tumor volume delineation. We hypothesize that the use of PET/CT in treatment planning can improve dose-escalation radiotherapy for NPC which in turn can improve therapeutic efficacy while reducing toxicity. PET/CT imaging of tissue hypoxia using [F-18]fluoromisonidazole (FMISO), the most widely used nitroimidazole imaging agent.Given that there has been no clinical trials directly comparing conventional chemoradiotherapy to CT-guided dose-escalation chemoradiotherapy or PET/CT guided dose-escalation chemoradiotherapy in locally advanced NPC.This was a study to evaluate the role of FMISO-PET hypoxia imaging for predicting survival in NPC,our study aims to compare the local control, overall survival and toxicities of the three treatment regimens..

The rationale for this study proposal is derived from previous case series demonstrating that up to 60% of patients with HNSCC, especially in the oropharynx are associated with high risk HPV infection. In this study, we will characterize the association between HPV infection and HNSCC in Israel and establish a program for its diagnosis and management based on HPV as a biomarker. The rationale for the proposed research is that once it is known which types of HPV are associated with HNSCC, this information can be used to direct diagnosis and screening effort to high risk population. Our approach is based on establishing a multicenter consortium of leading researchers that will establish a joint database of demographic, clinical and biological data from various regions in Israel. For this we have assembled a multidisciplinary research team with the scope and breath (surgical oncology, pathology, virology and molecular biology) needed to complete all phases of the research successfully. The research will be coordinated and performed at the Applied Cancer Research Laboratory, Tel Aviv Sourasky Medical Center. The patients will be recruited from 7 tertiary medical centers in Israel: Ichilov, Bellinson, Hadassa, Rambam, Soroka, Sheba and Nazeret..
