Leukoplakia

This study tests if a cream called imiquimod can treat pre-cancerous spots in the mouth. Twenty adults with these spots will apply the cream and get two follow-up biopsies. The goal is to see if the spots shrink and if the abnormal cells become less severe.

This study tests if injecting the cancer drug nivolumab directly into high-risk precancerous mouth lesions can stop them from turning into cancer. About 45 adults with these lesions will receive either the drug or a placebo injection. The goal is to see if the treatment is safe a…

This study tests whether metformin, a diabetes drug, can shrink or prevent precancerous mouth patches called oral leukoplakia. Researchers will give 34 adults a metformin gel applied to the lesion plus a metformin pill, or placebos. The goal is to see if the combination reduces l…

This study tests whether gels made with coenzyme Q10 or curcumin can shrink or stabilize precancerous white patches in the mouth called oral leukoplakia. About 34 adults with mild patches that don't need surgery will apply the gel daily. The goal is to see if these antioxidants c…

This study tests whether a combination of two diabetes drugs, pioglitazone and metformin, can shrink or improve precancerous patches in the mouth called oral leukoplakia. About 36 adults with high-risk lesions will take the pills twice daily for 12 weeks. The goal is to see if th…

This study tests whether using mobile health (mHealth) tools helps find early signs of oral cancer better than the usual visual exam in rural areas of Varanasi, India. Over 5,000 adults with risk factors like smoking, tobacco use, or age over 40 will be screened. The goal is to c…

This study tests a new imaging device called the Active Biopsy Guidance System to help doctors decide when and where to take tissue samples (biopsies) from mouth lesions. About 90 adults with suspicious mouth spots or a history of oral cancer will participate. The goal is to see …

This study is testing a new blood test called PanTum Detect to see how well it can find early signs of cancer or pre-cancer. The test looks for certain markers in immune cells. Researchers will compare the blood test results with standard PET/CT scans in 134 adults—half with susp…

This study tests an artificial intelligence system that assists doctors in determining how deep early esophageal cancer has spread, using endoscopic ultrasound images. The goal is to improve the accuracy of preoperative staging, which helps guide treatment decisions. Researchers …

This study collects extra blood, urine, and tumor samples from children and adults with certain cancers to build a large tissue repository. Researchers will analyze these samples to learn more about the genetic and molecular makeup of these tumors. The goal is to support future s…

This study is for 1000 people with oral cancer or precancerous mouth lesions. Researchers will collect tissue samples and ask participants about their symptoms before, during, and after treatment. The goal is to find better ways to predict how the disease will behave and which tr…

This study will analyze the genes of 25,000 adults who have cancer or are at risk for it. Researchers will use advanced testing to find genetic changes linked to cancer and track health records over time. The goal is to learn more about cancer biology and discover new ways to per…

This study collects tissue, blood, urine, and stool samples from 5000 people undergoing colonoscopy or endoscopy, including those with cancer, polyps, or inflammatory bowel disease, as well as healthy volunteers. The goal is to find new biomarkers that could improve early detecti…

This study compares two minimally invasive surgical techniques—laparoscopic and robot-assisted—for removing the left side of the pancreas in people with benign or pre-cancerous growths. About 256 participants will be randomly assigned to one of the two procedures. The goal is to …
