The purpose of this study is to determine whether sulindac and VSL#3 - inulin, either combined or alone, are effective in treating or preventing adenoma development in the ileal anal pouch in patients with familial adenomatous polyposis.

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.

Serrated polyposis syndrome (SPS) is a condition characterized by the presence of multiple serrated polyps (SPs) spread throughout the colorectum and is associated with an increased risk of colorectal cancer (CRC). SPS is defined by the World Health Organization (WHO) as the presence of at least 5 SPs proximal to the sigmoid colon, of which 2 ≥10 mm in size (WHO criterion 1), the presence of at least 1 SP proximal to the sigmoid and a first degree relative with SPS (WHO criterion 2), or more than 20 SPs spread throughout the colon (WHO-criterion-3). In practice only WHO 1 and WHO 3 criteria are used. The condition seems rather common and more prevalent than other polyposis syndromes such as familial adenomatous polyposis (FAP) (1:13.000). Several retrospective studies have shown that patients with SPS have an increased risk of developing CRC during endoscopic surveillance. Close endoscopic surveillance to prevent malignant progression of polyps has therefore been advised by several expert groups. However, due to a shortage of prospective data the optimal treatment and surveillance approach is largely unknown. The current study aims to prospectively evaluate the effectiveness and feasibility of a personalized surveillance protocol for patients with SPS to prevent CRC that is being used in several Dutch and Spanish hospitals. Furthermore, the polyp burden, colonoscopy complication risk and rate of conversion from endoscopic surveillance to colorectal surgery will be examined. For this purpose, all eligible SPS patients are prospectively enrolled 2013 onwards, and surveyed according to the study protocol. Based on the amount and characteristics of the polyps encountered during surveillance colonoscopy, the next colonoscopy will be scheduled after either 1 year or 2 years. Patients will undergo surveillance after 1 year in case of: Advanced adenoma (≥ 10 mm and/or high-grade dysplasia and/or 25% villous component) Serrated polyp ≥ 10mm and/or SP containing dysplasia Cumulative ≥5 sessile serrated polyps (SSPs) (irrespective of size), adenomas (irrespective of size) and/or hyperplastic polyps (HPs) ≥5mm Surgery needed during previous (clearing or surveillance) endoscopy Patients will undergo surveillance after 2 years in case none of above is reached

In the treatment of nasopharyngeal cancers, to determine the incidence of high grade (≥G2) subjective xerostomia at 1 year.

Nasopharyngeal carcinoma is a rare tumor among Caucasians which occurs with high incidence among individuals of Chinese descent. The disease is believed to have a multifactorial etiology with genetic, viral, and other environmental factors being involved. Little is known, however, about the genetic component of this disease. We have recently completed subject recruitment for a case-control study of NPC in Taiwan. Using information obtained from the NPC cases recruited into this NCI-sponsored case-control study as well as from a parallel cross-sectional study conducted by our Taiwanese collaborators, we have been able to identify 120-150 families with multiple family members affected with NPC. The purpose of the study described herein is to determine the role of inherited genetic factors in the etiology of NPC and to examine the effect of these genetic susceptibility factors on risk associated with environmental exposures. Families will initially be contacted via the proband who previously participated in our case-control and cross-sectional studies. Subsequently, informative family members will be asked to visit the study clinic to participate in the study. A family history questionnaire will be administered to the proband from each of the families selected for study. In addition, a risk factor questionnaire will be administered to all participating family members, and 30-40 ml of blood and an oral sample will be obtained from each study participant. Additional study components include medical record review to verify the diagnosis of NPC, retrieval of tumor tissue blocks as a source of DNA for study, and clinical exams on a sample of unaffected individuals to exclude the possibility of prevalent, undetected disease among family members. Oral and laryngeal cancer families will also be recruited in a manner similar to that described for NPC families, in an attempt to elucidate genetic factors linked to the development of these two cancers....

The goal of this research study is to test the first version of a website that will offer information and support for adolescents and young adults with FAP. Researchers want to see if the website will be helpful, easy to understand, and easy to use for young patients with FAP.

This research is being done to determine whether viral thymidine kinase (TK) expression in Epstein-Barr virus (EBV) and Kaposi's sarcoma herpesvirus (KSHV) virus-associated tumors is sufficient to image.

The Trans Tasman Radiation Oncology Group (TROG) has been commissioned by the Department of Health and Ageing to undertake a project to assess new Radiation Oncology Technology and Treatments. This project is being undertaken in response to a recognised need for the Medicare Benefits Schedule to support appropriate new radiation oncology technologies and treatments as they become available, to ensure optimal patient care. The first phase of the project required TROG to develop a Generic Research Framework (the Framework) capable of collecting and generating information to substantiate the safety, clinical efficacy and cost effectiveness of new technologies and treatments. The second (and current) phase of the project requires that the Framework be piloted to assess the safety, clinical efficacy and cost effectiveness of Intensity Modulated Radiation Therapy (IMRT) and Image Guided Radiation Therapy (IGRT) in four tumour site specific regions: A. Post Prostatectomy(IMRT) B. Anal Cancer (IMRT) C. Nasopharynx (IMRT) D. Intermediate Risk Prostate Cancer (IGRT) The aims of the site specific components of the ANROTAT protocol are as follows: Protocol A. Develop an approach for applying the Framework to evaluate the safety, clinical efficacy and cost-effectiveness of IMRT compared to 3DCRT in patients with prostate cancer (PP). Protocol B. Develop an approach for applying the Framework to evaluate the safety, clinical efficacy and cost-effectiveness of IMRT compared to 3DCRT in AC. Protocol C. Develop an approach for applying the Framework to evaluate the safety, clinical efficacy and cost-effectiveness of IMRT compared to 3DCRT in NPC. Protocol D. Develop an approach for applying the Framework to evaluate the safety, clinical efficacy and cost-effectiveness of IGRT compared to non-IGRT in patients with intermediate risk prostate cancer.

Radiation therapy remains the principal treatment for nasopharyngeal carcinoma (NPC). Although intensity modulated radiation therapy (IMRT) has been widely used in China nowadays, radiation dermatitis is still common. It has an impact on pain and quality of life, and if severe, may lead to interruption of the radiation schedule for the patient. Trolamine (Biafine; Genmedix Ltd, France) is commonly prescribed at the beginning of radiotherapy for preventing acute radiation-induced skin toxicity in China. However, as long as grade ≥2 radiation dermatitis is developed, trolamine is not allowed to use any more. Medical Radiation Protectants (FORRAD®) is a new kind of topical agents for prevention and treatment of radiation dermatitis. It could be used during the course of radiotherapy, even when grade ≥2 dermatitis is developed. This randomized phase II study is aimed to assess the effectiveness and safety of Medical Radiation Protectants (FORRAD®) for the prevention and treatment of acute radiation-induced dermatitis of grade 3 or higher during IMRT for patients with NPC, compared with trolamine.

Although patient-reported adverse events have been promoted as an essential element in clinical trials and daily managements, their efficacy remained unknown. The purpose of this trial was to determine the effect of the patient-reported adverse events during the treatment on the improvements on quality of life.
