Active clinical trials for "Nasopharyngeal Neoplasms"

Rationale: Familial adenomatous polyposis (FAP) syndrome is characterized by the development of numerous colorectal polyps. If left untreated, these patients have a chance of nearly 100% of developing colorectal cancer (CRC) at a young age. Therefore, guidelines recommend a prophylactic colectomy during early adulthood. Even after colectomy, most patients will develop adenomas in the retained rectum or ileoanal pouch requiring further endoscopic surveillance. In a recent study in mouse models, a chemopreventive effect of Lithium was observed on the spread of Apc mutated cells within the crypts of normal intestinal mucosa, suggesting polyp formation can be prevented. Lithium is used to treat patients with bipolar disorders but has never been investigated in patients with FAP aiming to reduce polyp burden. We hypothesize that Lithium could reduce the spread of APC mutated cells within the crypt of normal intestinal mucosa potentially reducing polyp burden in patients with FAP. Objective: The aim of this study is to investigate the effect of low-dose Lithium on stem cell dynamics, the number and size of polyps and, to assess safety outcomes of this drug in FAP patients. Study design: A prospective phase II, single arm pilot trial, with a duration of 18 months. The drug will be administered between month 6 and 12. Study population: Twelve patients with FAP between the age of 18 and 35 not having undergone a colectomy (yet), having a genetically confirmed APC mutation and a family history with a classical FAP phenotype. Intervention: All patients will be treated with Lithium with an oral dose of 300mg a day for six months, achieving a therapeutic serum level between 0.2-0.4 mmol/L. Main study parameters/endpoints: The main outcome parameter is the effect of Lithium on the spread of APC mutant cells within intestinal crypts over time by using an APC specific marker NOTUM (a significance reduce of fixed crypts and reduction of fixed clone size of 50%). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: A physical examination and an endoscopy with biopsies will be performed at baseline and every six months (four in total). Laboratory testing will be done at baseline and every two months during Lithium treatment. Patients will be interviewed by phone and Lithium side effect questionnaires will be obtained at baseline and during Lithium treatment. Lithium serum levels will be measured at day 12 and 22 after start of the study drug (at month 6). When the therapeutic range has been achieved, serum level testing will be done every month. Most relevant side-effects that could potential occur include polyuria, hyperparathyroidism and hypothyroidism. Most side effects are dose-dependent and will be regularly monitored. Patients with FAP could potentially benefit from a chemopreventive therapy such as Lithium to postpone or even avoid invasive types of surgery.

The aim of the study is to determine if Serrated Poliposis Syndrome (SPS) patients with SPS criteria 2, with clearing phase achieved and without any advanced lesion or less than 5 relevant lesions at last colonoscopy have the same advanced neoplasia incidence in the surveillance colonoscopy at 2 or 3 years. Patients selected for the study will be randomised in two groups for the surveillance: group 1, surveillance with colonoscopy in two years; group 2, surveillance with colonoscopy in three years. Randomization will be done at the database program (RedCAP). All colonoscopies will be performed with high definition (HD) system and it will be the choice of the endoscopist whether to use chromoendoscopy with indigo carmine o virtual chromoendoscopy. Protocol bowel preparation will be recommended by each centre. Sedation will be prescribed and decided by the endoscopist during the examination. Data from all the resected and visualized lesions during the colonoscopy will be collected on the database. A pathologist familiarized with serrated lesions will be in charge of the sample analysis. Serrated lesions will be classified attending de WHO criteria for serrated lesions. The investigators define "advanced adenoma" as adenomas ≥10 mm with villous histology and/or with high grade of dysplasia (HGD). The investigators define "advanced SL" as any SL ≥10mm and any SL with dysplasia. The investigators also define "advanced neoplasia" as any colorectal cancer (CRC), any advanced adenoma or advanced Serrated Lesions (SL). Quality of bowel cleansing will be graded by each endoscopist following the Boston Bowel Preparation Scale. This scale evaluates each segment (ascending colon, transverse colon and descending colon) of the following form: 0 = segment of colon whose mucosa cannot be seen due to the existence of solid stools that cannot be eliminated; 1 = mucosa portion of a colonic segment that can be seen, but other areas of the colonic segment are not seen, either due to the presence of dirt, feces or opaque liquid; 2 = existence of small amount of dirt, small fragments of stool and / or opaque liquid, but the mucosa of the colonic segment can be seen well; 3 = all the mucosa of the colonic segment can be seen well without residual dirt, small traces of stool or opaque liquid. Patients with inadequate preparation (when in any segment the score is 0 or 1, or the total score is less than 6) will be excluded from the study. During colonoscopy all complications as post-polypectomy bleeding, perforation or cardio-respiratory events will be registered. Those complications will be considered if surgery or hospital admission is required.

The study aims to describe the avidity of somatostatin receptors in locally advanced, metastatic and locally recurrent nasopharyngeal cancer (NPC) and to determine the proportion of NPC patients with high somatostatin receptor density that may benefit from future somatostatin targeted therapeutic trial plans. The investigators also aim to determine the presence of somatostatin receptors in other EBV related cancers.

This study investigates if head and neck squamous cell carcinoma can be tracked with cell-free tumor DNA, RNA or HPV-DNA, in blood samples from patients referred with suspicion of cancer, and if it can be used in detecting recurrence in patients already diagnosed and treated for head and neck squamous cell carcinoma.

Multicentre , non-randomized, prospective clinical trial to assess efficacy of Nivolumab in treatment of nasopharyngeal cancer who progressed during or after platinum-based chemotherapy . Patients disqualified from radical therapy . The total number of patients was estimated for 32.

This study is aimed to estimate the effectiveness of an Epstein-Barr virus (EBV) serology-based screening program to reduce nasopharyngeal carcinoma (NPC) mortality in a cluster randomized controlled trial in an NPC high-risk population. Sixteen towns in Sihui and Zhongshan Cities, China will be selected, with eight allocated to the screening group and eight to the control group. Cantonese residents aged 30-69 years with no history of NPC will be included. Residents in the screening towns will be invited to undergo serum EBV VCA/EBNA1 IgA antibody tests.

First-diagnosed metastasis or recurrence/metastasis NPC Patients will be treated with anlotinib, penpulimab and capecitabine.

The investigators hypothesize that the addition of bevacizumab and pembrolizumab to induction cisplatin and gemcitabine is tolerable and improves metabolic complete response (mCR), relapse free survival (RFS) and overall survival (OS) compared to induction cisplatin and gemcitabine in patients with locally advanced nasopharyngeal cancer (NPC)

RATIONALE In patients with nasopharyngeal carcinoma, there is sometimes a discrepancy between actual clinical outcome and TNM stages because it is an anatomy-based system in which functional factors are not concerned. Hemoglobin, neutrophil to lymphocyte ratio and platelet count were proved to improve prognosis prediction of TNM staging system in our previous retrospective study. PURPOSE To validate that the prognostic index based on complete blood count and TNM system had higher prediction efficiency on survival in nasopharyngeal carcinoma than TNM system alone.

This is a single center, randomized, phase Ib/II open-label study of pembrolizumab (pembro or MK-3475) with or without bevacizumab in patients with recurrent non-curable or metastatic nasopharyngeal carcinoma (NPC).
