Assessing the Additional Neoplasia Yield of Computer-aided Colonoscopy in a Screening Setting
Colonic NeoplasmsColonic Adenocarcinoma3 moreEven if colonoscopy is considered the reference standard for the detection of colonic neoplasia, polyps are still missed. The risk of early post-colonoscopy cancer appeared to be independently predicted by a relatively low polyp/adenoma detection rate. When considering the very high prevalence of advanced neoplasia in the FIT-positive enriched population, the risk of post-colonoscopy interval cancer due to a suboptimal quality of colonoscopy may be substantial. Available evidence justifies therefore the implementation of efforts aimed at improving adenoma detection rate, based on retraining interventions and on the adoption of innovative technologies, designed to enhance the accuracy of the endoscopic examination. Artificial intelligence seems to improve the quality of medical diagnosis and treatment. In the field of gastrointestinal endoscopy, two potential roles of AI in colonoscopy have been examined so far: automated polyp detection (CADe) and automated polyp histology characterization (CADx). CADe can minimize the probability of missing a polyp during colonoscopy, thereby improving the adenoma detection rate (ADR) and potentially decreasing the incidence of interval cancer. GI Genius is the AI software that will be used in the present trial and is intended to be used as an adjunct to colonic endoscopy procedures to help endoscopists to detect in real time mucosal lesions (such as polyps and adenomas, including those with flat (non-polypoid) morphology) during standard screening and surveillance endoscopic mucosal evaluations. It is not intended to replace histopathological sampling as a means of diagnosis. The objective of this study was to compare the diagnostic yield obtained by using CADe colonoscopy to the yield obtained by the standard colonoscopy (SC).
Audit of Surgery for Colorectal Cancer
Rectal AdenocarcinomaColon AdenocarcinomaThe aim of this project is to audit the surgical care in patients treated for colorectal adenocarcinoma. This study focused on collecting data from all consecutive cases of colon and rectal adenocarcinoma operated at the National Institute of Oncology in Rabat during a two-years period. Using standardized forms, the investigators collected data relating to each stage of treatment: pre-therapeutic, surgical and post-operative in order to measure the quality of the surgical care delivered. These results were compared to established benchmarks and to similar audit studies carried out in other countries around the world.
Early Access Program for Zolbetuximab
Locally Advanced Unresectable Gastroesophageal Junction (GEJ) Adenocarcinoma CancerLocally Advanced Unresectable Gastric Adenocarcinoma Cancer2 moreThis program is to provide zolbetuximab to people with stomach cancer or gastroesophageal junction (the junction between stomach and esophagus) cancer who have not yet been treated with chemotherapy, immunotherapy, or zolbetuximab and who have tested positive for claudin18.2 (a protein found in some cancer cells). People will work with their doctor to see if they are capable of being treated with zolbetuximab while they receive other standard medicines to treat their cancer. The program will allow people early access to zolbetuximab before the drug is fully approved. Zolbetuximab will be given through a vein. This is called an infusion. The infusion will happen during a person's treatment with other cancer medicines. Zolbetuximab will be given every 3 weeks. People will continue treatment until: they have medical problems (unwanted side effects) from the treatment; their cancer gets worse; they start other cancer treatment; they ask to stop treatment; or they do not come back for treatment. People will visit the clinic on certain days during their treatment. During these visits, the program doctors will check for any medical problems (unwanted side effects) from zolbetuximab, other cancer treatment, or both. At some visits, other checks will include a medical examination, laboratory tests and vital signs. Vital signs include temperature, pulse, and blood pressure. Also, blood and urine samples will be taken. People will visit the clinic within 7 days after stopping treatment. The program doctors will check for any medical problems (unwanted side effects) from zolbetuximab or their cancer treatment. Other checks will include a medical examination, laboratory tests, and vital signs. Then, people will have a follow-up visit about 30 days after stopping treatment. If people are having no health problems, the follow-up visit can happen over the telephone.

Adenocarcinoma of the Esophagogastric JunctionThis study have two aims, the first is to explore the optimal cutoff of TLN for Siewert type II AEG using the Surveillance, Epidemiology, and End Results (SEER) database the second is to provide a more accurate staging for Siewert type II AEG patients.
Germline Mutations Associated With Hereditary Pancreatic Cancer in Unselected Patients With Pancreatic...
Pancreatic CancerPancreatic AdenocarcinomaPancreatic cancer is a highly lethal disease. The cause of pancreatic cancer is multifactorial. However, around 10% of cases are associated with hereditary predisposition. Germline mutations in BRCA1 and BRCA2, CDKN2A, STK11, DNA mismatch repair (MMR) genes (MLH1, MSH2, MSH6, or PMS2), PALB2, FANCC, FANCG, and ATM have been associated with an increased risk for pancreatic cancer. The prevalence of these germline mutations varies across populations. For instance, the prevalence of BRCA1/2 germline mutations in high-risk populations can be up to 20%. On the other hand, in unselected patient population, the prevalence of BRCA1/2 germline mutations is 5-7%. In Mexican population, data on the prevalence of BRCA1/2 germline mutations in patients with pancreatic cancer are lacking. Identification of BRCA germline mutations in patients with pancreatic cancer has implications for treatment. Also, it allows genetic testing and counselling for family members. This study will determine the prevalence of germline mutations associated with hereditary pancreatic cancer using a comprehensive gene panel in an unselected cohort of patients with pancreatic adenocarcinoma in Mexico.
EGFRdelEx19 and KRAS Exon 2 Mutation Detection in EBUS-TBNA
Lung Adenocarcinoma MetastaticFirst-line treatment with afatinib prolongs overall survival in patients with metastatic non-small-cell lung cancer (NSCLC) harboring EGFR exon 19 deletion mutations. Conversely, somatic KRAS mutations are negative predictors for benefit from EGFR-targeting agents. In this study we want to compare a new highly sensitive method for the detection of EGFRdelEx19 and KRAS Exon 2 with targeted-resequencing multiplex-PCR (NGS).
PAncreatic Adenocarcinoma in Hospital
Pancreatic AdenocarcinomaFew data are currently available in the literature on pancreatic adenocarcinoma in France. About 8,000 new cases each year in France. The 5-year survival for all stages combined is <5%. This is the only digestive cancer in which mortality / incidence ratio is 98%. Epidemiological characteristics at diagnosis, the impact on the survival of recent advances related to surgery, adjuvant chemotherapy and new standard forms of adjuvant chemotherapy (FOLFIRINOX) are mispriced in real life. The development of new drugs and the development of Phase II and III require a better understanding of the state of this disease in the country. The main objective is to describe the characteristics of the pancreatic adenocarcinoma at diagnosis in France and make an inventory of diagnostic practices and support.
Prevalence of Dysplasia of the Gastric Cardia
Barrett's EsophagusIntestinal Metaplasia1 moreWe propose a tissue sample collection study for patients at UNC who have undergone or will undergo radiofrequency ablation therapy for Barrett's Esophagus (BE) or intramucosal adenocarcinoma as part of routine medical care. Purpose: To determine the prevalence of metaplasia and dysplasia in the gastric cardia before and after ablative therapy. To determine the incidence of cardiac metaplasia and dysplasia as a function of ablative therapy. To determine the correlation between dysplasia in the tubular esophagus, and dysplasia in the cardia. To assess the ability of immunohistochemical (IHC) staining of cardia tissues to predict incident dysplasia in the cardia. Several well-characterized biomarkers, including p16, p53, Ki67, cyclin D1, and cyclin A, will be assessed.
A Correlative Study of Biomarkers of Resistance in Patients With Castrate Resistant Prostate Cancer...
Prostate Cancer (Adenocarcinoma)Adrenal androgens are serum biomarkers of interest that may help guide abiraterone acetate treatment, particularly at the time of progression. Biomarkers may also help identify pathways to resistance of abiraterone acetate treatment. The most practical way of approaching this question is to explore surrogate biomarkers of prostate cancer including quantification of pharmacodynamic endocrine biomarkers.
