Filter by:This trial intends to enroll patients with T4N1 or T1-4N2-3 (AJCC 8th) locoregionally-advanced nasopharyngeal carcinoma (LANPC). All the Patients will receive 3 cycles of induction chemotherapy with docetaxel and cisplatin and cisplatin based concurrent chemoradiotherapy (CCRT) plus adjuvant immunotherapy (tisleilizumab). All patients will receive intensity-modulated radiotherapy (IMRT). Tisleilizumab will begin 4-6 weeks after CCRT and continue every 3 weeks for 12 cycles.
Colorectal cancer (CRC) is a leading cause for cancer related mortality in the western world with a lifetime risk of 6%. Etiology is complex, while genetic background significantly affects the risk. Around one third of all genetic disorders as well as most cases of Familial Adenomatous Polyposis (FAP) and a large proportion of all sporadic CRC cases occur as a result of premature nonsense mutations (creating a stop codon) in an individual's adenomatous polyposis coli (APC) gene. Nonsense mutations are single-point alterations in the DNA that prematurely halt the protein translation process, producing a shortened, nonfunctional protein. In many of these cases, if the cell can be 'persuaded' to ignore the premature stop codon signal, the resulting protein may be able to ameliorate or stop the disease. Recently, members of the aminoglycoside family of antibiotics have been found to induce ribosomal read-through of nonsense mutations, leading to expression of a full length, functional protein. Investigators have recently shown that members of the aminoglycoside and macrolide antibiotic families can induce read-through of the nonsense mutations in the APC gene and lead to reduced oncogenic phenotypes in CRC cells and in different mice models. The aim of this project is to determine the ability of the macrolide antibiotic-Azithromycin to induce read-through of the nonsense mutations in the APC gene and to induce expression of a full length, functional APC protein in patients suffering from FAP and to tests its effect on adenoma number and size and on desmoid tumors in these patients. The future goal is to maximize the effect of stop-codon suppressors on APC while minimizing side effects. In this study the investigators will select FAP patients which carry APC nonsense mutations, treat them with Azithromycin PO for 4-6 months and examine colonic and duodenal adenomas as well as abdominal desmoid tumors, that will be documented before during and after treatment. In parallel, investigators will test polyp, adenoma and desmoid tissue samples as well as blood samples from these patients for changes in expression levels of the APC protein and related oncogenic markers. Suppression of nonsense mutations within the APC gene should be of benefit for patients suffering from FAP, attenuated FAP or multiple adenomas and for patients with advanced or diffuse CRC. Furthermore, given the rapid progress being made in the identification of different nonsense mutations in human genes that lead to mostly non-curable disease, the identification of clinically approved compounds that suppress nonsense mutations and that can be administered long-term without significant side effects would open new venues in the treatment of genetic human diseases that arise from pre-mature stop codons in important coding sequences. Immediate goal: establish the ability of Azithromycin to read-through APC nonsense mutation in FAP patients. The read-through effect of Azithromycin will be clinically tested by counting and measuring the number and size of both colonic and duodenal adenomas before and over treatment and by measuring the size of known desmoid tumors. Samples of the adenomas and desmoid tumors will be tested by western blot, immunofluorescence and immunohistochemistry for restoration of APC expression and changes in oncogenic markers. These experiments should be conducted within 6 month. Long term objective: 1. Determine the lowest dose of Azithromycin that can inhibit growth of colonic neoplasia and CRC in patients expressing a truncated APC protein due to nonsense mutations. 2. Examine the ability of a panel of additional macrolide antibiotics to induce APC nonsense mutation suppression using in-vitro methods. Investigators will focus on macrolide antibiotics that are currently in clinical use and are administrated for long terms. These objectives should take around 4 month and will be conducted in parallel.
This is an open-label, parallel controlled, phase IIa exploratory study that evaluates the efficacy and safety of Toripalimab (PD-1 Antibody) combined with induction chemotherapy （Albumin-bound paclitaxel and cisplatin ）and concurrent chemoradiotherapy in the treatment of nasopharyngeal carcinoma and explores the biomarkers that can predict the efficacy and toxicity of the treatment.
Nasopharyngeal carcinoma (NPC) is endemic in our region and is the 9th most common cancer in Hong Kong. Traditionally diagnosis has been through a nasoendoscopic examination of the nasopharynx with white light followed by a biopsy of suspicious lesions for a confirmatory diagnosis. However, given the geometry of the anatomy of the nasopharynx, with its inherent crevices and varying amounts of lymphoid tissues, lesions are not always easily identified leading to potential missed lesions. The non-specific aspect of white light also leads to excessive biopsies that are not without risk and of some discomfort to patients. Recent advances in liquid biopsies have also allowed for the detection of earlier and smaller lesions that are not always easily identified on nasoendoscopy but rather are seen on Magnetic Resonance Imaging (MRI)1 . An alternative imaging technique is the use of Narrow Band Imaging (NBI) to view the vasculature of the mucosa to identify suspicious lesions for pre-malignancy and malignancy that has been popularized in the gastrointestinal tract. In NPC, NBI with the flexible nasoendoscopes has been used in the diagnosis of NPC with varying success2-5 . Our own group's research has found that in NPC NBI has limitations arising from a lack of consensus on vascular findings on NBI that constitute malignancy, lack of magnification and long focal length of current nasoendoscopes5-8 . Flexible endoscopy using conventional esophago-gastroscopy endoscope (OGD) with NBI and magnification power up to 80x overcome the limitations of current nasoendoscopes, however their size precludes the passing of these endoscopes through the nasal cavity. Here in this pilot study we will seek to use an OGD with NBI passed transorally and retroflexed into the nasopharynx to view the nasopharynx with increased magnification and clarity to evaluate the feasibility of this study in the diagnosis of nasopharyngeal carcinoma. Study questions: 1. Is it feasible to use an OGD with magnifying NBI for the diagnosis of NPC? 2. Are there features detected on NBI OGD that are diagnostic of NPC? 3. Do histological features correspond with NBI findings?

Half of participants will receive morphine controlled-release tablets,while the other half will receive fentanyl transdermal patch.
Cancer is a global health issue. According to the World Health Organization, Cancer is the second leading cause of death globally, and is responsible for an estimated 9.6 million deaths in 2018. In Israel, more than 30,000 new cases of cancer were diagnosed, and more than 11,000 deaths were cancer-related during 2016. Imaging plays a pivotal role in cancer management, and multiple techniques are used in all phases of cancer management. The overall morphological, structural, metabolic and functional information obtained in imaging is used for improved individualized therapy planning. Different imaging modalities are available during different time points in the natural history of different malignancies: Early detection of cancer through screening based on imaging is probably a major contributor to a reduction in mortality for certain cancers . Once a diagnosis is made, determining the clinical stage of cancer, meaning the extent of the disease before any treatment is given, is a critical element in determining appropriate treatment based on the experience and outcomes of groups of previous patients with similar stage . Precise clinical staging of cancer is crucial. Not only that this clear non-ambiguous description is a key factor that defines prognosis, it is also a chief component of inclusion, exclusion, and stratification criteria for clinical trials. Several cancer staging systems are used worldwide. The most clinically useful staging system is the tumor, node, and metastasis (TNM) staging system developed by the American Joint Committee on Cancer (AJCC) in collaboration with the Union for International Cancer Control (UICC). The AJCC TNM system classifies cancers by the size and extent of the primary tumor (T), involvement of regional lymph nodes (N), and the presence or absence of distant metastases (M). There is a TNM staging algorithm for cancers of virtually every anatomic site and histology, with the primary exception of pediatric cancers. The clinical TNM (cTNM) classification should be used to determine correctly the clinical stage of cancer and to help guide primary therapy planning.
Nasopharyngeal carcinoma (NPC) is commonly observed in southern China, particularly in the Pearl River delta area and the Xijiang River basin in the Guangdong and Guangxi provinces, with an incidence rate as high as 25‑50 per 100,000. The National Comprehensive Cancer Network guidelines (version 1, 2018), have recommended use of induction chemotherapy followed by CCRT as category 2A for NPC, especially the TPF regimen as category 1 for EBV-associated disease. The nanoparticle albumin-bound paclitaxel (Nab-paclitaxel) is a promising new agent with more efficient entry to the tumor microenvironment and preferential uptake by cancer cells. Superior activity of Nab-paclitaxel regimens without the necessity for antianaphylactic pretreatments has been shown in various solid tumors compared with the traditional solvent-based paclitaxel-based ones. However, the safety and efficacy of combination of Nab-paclitaxel, cisplatin and Fluorouracil (APF) has not been determined in patients with locoregionally advanced NPC. In this prospective, Multi-centeric, Open, Non-controlled phase II clinical trial, investigators perform an exploratory study to the efficacy and Safety of APF.
