Filter by:This study aims to find a correlation between fish protein intake and other dietary habits and colorectal premalignant lesions in healthy volunteers. It also aims to describe gut microbial profiles for each dietary pattern, in order to elucidate the role of fish intake in cancer prevention.
The goal of this observational study is to analyze somatic mutations in the genome of normal kidney cells from patients affected by kidney cancer predisposition syndrome Von Hippel Lindau (VHL) and compare the mutation rates observed in these patients and in individuals not affected by the disease. The main questions the study aims to answer are: - Do kidney cells from VHL patients mutate more than cells from control individuals during adult life? - What mechanisms favor somatic mutation occurrence in the genome of normal kidney tubule cells? Participants will donate one blood sample and multiple urine samples. Urines will be used for kidney cell isolation, followed by cell culturing and genetic analyses. Urine samples will be collected once a year for 3-5 years. Sample collection will occur during the yearly screening program that each patient undergoes at the hospital. In case patients undergo surgical treatment of kidney tumors, samples discarded from surgery (tumor and normal kidney adjacent to tumor) will be collected and subjected to genetic analyses. Researchers will compare the number and types of mutations found in tumors and normal kidney cells from VHL-disease patients with those found in normal kidney cells from control individuals, to see if somatic mutation rates are increased in VHL-disease patients during aging.
To investigate the use of self-administered artesunate vaginal pessaries as treatment for cervical precancer in low and middle-income countries (LMIC). The central hypothesis of this study is that self-administered intravaginal Artesunate will be safe, and result in a clinical response among both HIV-positive and HIV-negative women with cervical precancer in LMICs.
The goal of this study is to characterize and validate a signature of circulating biomarkers in plasma, associated with the presence of gastric preneoplasia in patients with preexisting gastric lesion compared with a control group. For this purpose: - Patients with pre-existing gastric lesions will be invited to participate to this study. If they are willing to participate an additional blood sample (10mL) will be collected at the time of the blood collection performed during their routine care - Healthy subjects will be invited to participate to constitute the control group. If they are willing to participate a blood sample (10 ml) will be drawn specifically for this study
This case-control study aims to investigate if oral microbioma is associated with developing oral (pre)malignant disease.
The aim of this diagnostic accuracy study is to evaluate the application of artificial intelligence on the diagnosis of Helicobacter pylori infection and premalignant gastric lesions based on upper endoscopic images. We use techniques of artificial intelligence to analyze the correlation between endoscopic images and urea breath test results/histopathological results.
We aimed to analyze postoperative short-and long-terms clinical outcomes after the Triangle procedure in patients with Pancreatic head, periampullary and duodenal cancer.
In this study, the investigators will prospectively collect, analyze and integrate information regarding vaginal microbiome composition and HPV presence in women with cervical pathologies (high-grade CIN and CC) and controls, to construct a large dataset from patients with pre-cancerous cervical lesions and healthy women, to evaluate the personalized contribution of the vaginal microbiome to the CIN-CC sequence.
To evaluate the design, safety and efficacy of OralViome Cancer Testing system in the early detection of Oral and Throat Cancers using saliva metatranscriptomic analysis. This study will recruit only at existing clinical sites and will NOT use any additional clinical sites.
To characterize the safety and tolerability of nivolumab injected intralesionally in patients with high-risk oral premalignant lesions.
