Active clinical trials for "Carcinoma"

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.

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.

Tumor is the primary public health problem and the incidence of esophageal cancer showed the increasing trend in the past thirty years. According to the statistics in 2015, the new onset of esophageal cancer is about 477,900 yearly. The mainly pathologic type of esophageal cancer in China is esophageal squamous cell carcinomas, which accounts for more than 90% of patients in China. With the development of endoscopic technics, more and more patients choose to receive the endoscopic procedure rather than traditional surgery. However, the long-term efficacy and outcomes of patients with superficial esophageal squamous cell carcinoma received different interventions remained unclear. Thus, investigators aim to conduct a multi-center retrospective study to investigate the long term outcomes of superficial esophageal squamous cell carcinoma patients receiving endoscopic treatment and surgery.

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

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.

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

High risk papillomavirus (HR-HPV) have an oncogenic role in Oropharyngeal squamous cell carcinomas (OP-SCC) in at least 25% of the cases and the prevalence is increasing. HPV+ might be more chemo and radio sensible with a better prognosis (disease-free survival (DFS) and overall survival (OS) as compared to HPV negative OP-SCC ; hypothesis : 2y DFS > 20% improvement). The principal objective is to determine the impact of the status of HR-HPV in the prognosis of the OP-SCC. The principal criteria is the 2-years DFS. Secondary objective : virologic characteristics of HPV+ tumors.

Investigate the final diagnosis and treatment result of metastatic cervical carcinoma of unknown primary

Extended pelvic lymph node dissection in bladder carcinoma provides staging and, in selected patients, a survival benefit. Recent studies showed the therapeutic benefit of retroperitoneal lymph node dissection (RPLND) in advanced stage of upper tract urothelial carcinoma (UTUC). Also laparoscopic extended RPLND is still a technical challenge in urology, considering the high rate of severe complications and difficulties in manipulation. In Renji Hospital, laparoscopic extended RPLND at time of nephroureterectomy was performed via an extraperitoneal approach, avoiding interference with abdominal organs and achieving better exposure.The aim of the present study was to determine the safety and feasibility of performing an extraperitoneal laparoscopic extended RPLND at the time of radical nephroureterectomy (RNU) for UTUC in a prospectively collected cohort of patients.

According to the World Health Organization, oral cancer (OC) is the eighth most common cancer in the world with a five year survival rate of 50%. Oral cancer tumor cells produce biochemical substances, tumor markers, differed from healthy individuals in expression or quantitative ratio, detectable in tissues and/or body fluids. Saliva, because of its accessibility, proximity and noninvasive approach, presents an ideal tool for the research of oral cancer tumor markers. The aim of this study will be to isolate, quantify, analyze the role and describe the kinetics of diadenosine tetraphosphate (Ap4A), Squamous Cell Carcinoma associated Antigen (SCCA), Trophoblast cell surface antigen (TROP2) in patients with OC, potentially malignant disorders (PMOD) and age and sex matched control group with a clear medical history. There are number of studies published on OC tumor markers isolated mostly in serum, however the satisfactory specificity and sensitivity still hasn't been reached. Liquid chromatography-ion trap-mass spectrometry, Multiple Reaction Monitoring method (LC-IT-MS, MRM) will be developed to isolate and quantify the above mentioned tumor markers. This method has not yet been used to quantify the above mentioned salivary tumor markers. Ap4A and TROP2 have never been isolated from saliva. The aim is to develop a tumor-specific test with a satisfactory statistical sensitivity and specificity and dynamically measure the levels of tumor markers, before and immediately after therapy - surgery/radiotherapy/chemotherapy or their combination, and during regular follow-up one and two years after surgery. As another novelty, the investigators aim to determine the markers circadian rhythm. A OC tumor specific test, with satisfactory sensitivity and specificity, would enable earlier OC diagnosis, possibly before the clinical appearance, raise the survival rate of OC patients, enable early diagnosis of recurrence and/or new primary tumors and ensure better post-treatment life-quality.
