Active clinical trials for "Carcinoma"

Primary treatment in nasopharynx cancers is radiotherapy (RT) or chemoradiotherapy (CRT) depending on the stage of the tumor. According to the guidelines, the dose of radiotherapy for primary tumors varies between 66-70 Gy. In consideration of modern radiotherapy techniques like IMRT with systemic chemotherapy for nasopharyngeal cancer, loco-regional control has been perfect. However, the rate of late complications from treatment, many of which are irreversible, is still high. Radiation-related optic neuropathy is the late complication that optic nerves might be affected during the radiotherapy due to the close location of the nasopharynx. Incidence of this is 8.7-9% in head and neck cancer and is observed between 2-9 years after RT. Painless, irreversible, and progressive vision loss usually occurs, and the pallor of optic disc margins, retinal vein dilatation, bleeding, and neovascularization are in the ophthalmic examination. The risk of optic neuropathy increases when the tumor is in close contact with optic nerves, radiation dose, concurrent chemotherapy used, history of diabetes or hypertension. The aim of our study is to prospectively evaluate optic neuropathy in nasopharynx cancer patients treated in our clinic.

This is a multicenter, prospective, observational study in which subjects will be treated with lenvatinib combined with TACE in un-resectable HCC patients who had not received systematic treatment or TACE treatment in the past.

Immunotherapy has become an essential therapeutic weapon against many cancers. Control point inhibitors (CPI, PD-1/PD-L1) have shown efficacy in the therapeutic management of tumors in the bladder in progression after administering platinum derivatives. But only 20% of patients get any clinical benefit from these heavy treatments in the long term. Treating metastatic patients without distinction means taking a considerable risk of toxicity and generates major costs. It is therefore urgent and important to exceed the current criteria for using immunotherapy. Recent studies have shown the interest of studying intestinal microbiota as a marker of the efficacy of immunotherapy. The investigators hypothesized that the proteomic signature of the intestinal microbiota in patients with locally advanced or metastatic urothelial carcinomas who responded to immunotherapies was special, and has very different characteristics from that of patients with the same pathology who do not respond to immunotherapy.

Study purpose: To evaluate the efficacy and safety of Tislelizumab in combination with advanced hepatocellular carcinoma in the real world; Study design: Non-intervention, single center, case registration, real-world study; Number of registrations: 40; Source of data: This project is a non-interventionary real world case follow-up registration. All registration data are from real clinical practice cases. The collected data include the following requirements: Age ≥18 years old; Unresectable hepatocellular carcinoma confirmed by histological examination or clinical diagnosis; Plan or have received systemic therapy combined with Tiralizumab; No participation in other clinical studies; Access to Tislelizumab treatment and other clinical records; Primary endpoint: Overall response rate; Secondary endpoint: Disease control rate, progress free survival, overall survival, safety; Exploratory endpoint: To explore the predictive value of multiple Biomarker combinations, such as PD-L1, TMB, MSI, DDR, POLE/POLD, in HCC immunotherapy response.

The chemo-radiotherapy for the local advanced nasopharyngeal carcinoma patients will induce the mucosal ulcer and damage salivary glands. Consequently, it can disturb the nutrition conditions and clinical outcomes of patients. This research tries to evaluate the nutrition status at the baseline, before and after radiotherapy, during the follow-up by the body mass index, hematological indexes, immunological indexes, and nutrition questionnaires including PG-SGA and NRS 2002. Through the evaluation of two different nutritional interventions, the investigators aim to find an optimized assessment model and the best nutrition support patterns.

The peritoneum is the second most common site of recurrence in patients with colorectal cancer. Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy improve the prognosis of these patients and incorporates surgical removal of all visible disease followed by chemical destruction of microscopic disease through chemoperfusion. The most validated predictors of outcome are preoperative tumor burden measured in terms of the peritoneal carcinomatosis index (PCI) and completeness of cytoreduction (CC score). Diagnostic laparoscopy prior to resection is widely used in hepatopancreaticobiliary and colorectal cancer and has been shown to be effective in excluding unnecessary laparotomy associated with higher morbidity.

Esophageal carcinoma is a lethal disease, causing more than 400,000 deaths annually worldwide. Primary surgery results in microscopically positive resection margins (R1) in 25% patients, and the 5-year overall survival(OS) for such patients rarely exceeds 40%. Concurrent chemoradiation followed by surgery results in better survival than single-modality treatments, and thus National Comprehensive Cancer Network(NCCN) recommends concurrent chemoradiation as preoperative or definitive treatment for patients with stage II or III esophageal cancer. However, neoadjuvant chemoradiation may not be effective in some subgroup of these patients, and its toxicity can increase perioperative mortality and delay or preclude surgery. The ability to distinguish tumors that will respond or not respond to such therapy remains an urgent priority. Diffusion-weighted magnetic resonance imaging(DW-MRI) is based on the extent of mobility of water protons, as quantified by the apparent diffusion coefficient (ADC). The ADC is a measure of the extent of free diffusion of water molecules within tissues, which is mainly influenced by cell organization, size, and density. Cell death leads to a loss of cell membrane integrity and density and leads to increases in ADC values. The ADC has emerged as a potential biomarker of response to cancer therapy. However, no one has published findings regarding the potential correlation between changes in ADC and response of esophageal cancer to chemoradiation. Clarifying the potential predictive value of DW-MRI for predicting response to such therapy is important for the delivery of appropriately tailored treatment. Investigators hypothesized that DW-MRI can predict the success (or failure) of neoadjuvant chemoradiation in esophageal squamous cell carcinoma（ESCC）, hence identify patients at high risk of treatment failure from such therapy. Investigators will test this hypothesis with two specific aims: (1) assess the ability of ADC to predict pathologic response to treatment; and (2) assess the ability of ADC to predict disease-free survival and overall survival.

This is a prospective, observational cohort study aimed to explore the influence of anxiety and depression to long term survival in nasopharyngeal carcinoma patients.

This study is a randomized control prospective study. The aim of this study is to establish an all-round and convenient follow-up strategy of Chronic Hepatitis B for early detection and diagnosis of Hepatocellular Carcinoma (HCC), by investigating whether different surveillance time intervals and surveillance methods are beneficial for chronic hepatitis B and cirrhotic patients with different risk of HCC.

Tobacco and alcohol are the two major risk factors for upper respiratory tract cancer (VADS).
