15 Clinical Trials for Precancerous condition
The goal of this study is to understand the safety, tolerability, and potential efficacy of an injected immune therapy called RP2 to treat oral precancer conditions and prevent progression to an oral cancer. The name of the study drug involved in this study is: -RP2 (a genetically modified live Herpes Simplex V-1 strain)
Primary: * To measure the rate of perioperative vulvovaginitis in a population of patients in central VA with non-malignant vulvar disease who require surgical excision * To correlate the rate of vulvovaginitis with rate of wound cellulitis and incisional breakdown in patients undergoing SPV/WLE for vulvar disease We will use a vulvovaginal swab to test for the most common causes of vulvovaginitis - bacterial vaginosis (BV), trichomonas, and candida. The swab will be collected preoperatively on day of surgery. The outcome will be evaluated by phone call to patient at 1 week after surgery and physical exam at the postoperative visit between 4-6 weeks.
Gastric cancer afflicts 27,000 Americans annually and carries a dismal prognosis. One reason for poor outcomes is late diagnosis, as the majority of gastric cancers in the United States are diagnosed at a relatively advanced stage where curative resection is unlikely. Gastric precursors (such as atrophic gastritis and intestinal metaplasia) are precancerous changes to the stomach mucosa which increases risk for subsequent gastric cancer. The Gastric Precancerous Conditions Study (GAPS) is an observational study of patients at elevated risk for gastric cancer. Investigators seek to recruit patients from endoscopy unit of Stanford Health Care, a large academic network of hospitals and clinics serving Northern California. Investigators will recruit patients who are both symptomatic (e.g. dyspepsia) and asymptomatic (e.g. referred for screening), and individuals both with known precursor lesions (such as intestinal metaplasia) or at high risk for carrying precursor lesions. A component of the study is long-term follow-up of individuals with gastric precursors. This is to understand their risk factors for histologic progression and regression. During both index and subsequent endoscopies, the study team will collect biospecimens (e.g. blood, saliva, gastric tissue).
To evaluate the antitumor efficacy of intralesional injections of nivolumab in patients with high-risk oral premalignant lesions
To evaluate clinical outcome for patients receiving treatment of suspected premalignant and malignant gastrointestinal lesions at Interventional Endoscopy Services. The primary outcome is curative endoscopic resection. Secondary outcomes include resection technique utilized, rates of en bloc resection and adverse event rates, including infection, bleeding, perforation and death, and one-year survival rates.
This research study is creating a way to collect and store specimens and information from participants who may be at an increased risk of developing cancer, or has been diagnosed with an early phase of a cancer or a family member who has a family member with a precursor condition for cancer. * The objective of this study is to identify exposures as well as clinical, molecular, and pathological changes that can be used to predict early development of cancer, malignant transformation, and risks of progression to symptomatic cancer that can ultimately be fatal. * The ultimate goal is to identify novel markers of early detection and risk stratification to drive potential therapeutic approaches to intercept progression to cancer.
RATIONALE: Studying samples of sputum and tissue in the laboratory from patients with dysplasia or cancer may help doctors identify and learn more about biomarkers related to cancer. It may also help the study of cancer in the future. PURPOSE: This laboratory study is looking at biomarkers in patients with respiratory tract dysplasia or lung cancer, head and neck cancer, or aerodigestive tract cancer.
RATIONALE: Studying samples of tissue, blood, urine, stool, and other biological fluids from patients with cancer and from healthy volunteers undergoing colonoscopy or endoscopy may help doctors identify and learn more about biomarkers related to cancer. PURPOSE: This research study is looking at gastrointestinal biomarkers in tissue and biological fluid samples from patients and participants undergoing colonoscopy, endoscopy, or surgery.
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.
The goal of this clinical trial is to determine the effectiveness of Reduced Dose Post-Transplant Cyclophosphamide (PTCy) in patients with hematologic malignancies after receiving an HLA-Mismatched Unrelated Donor (MMUD) . The main question\[s\] it aims to answer are: * Does a reduced dose of PTCy reduce the occurrence of infections in the first 100 days after transplant? * Does a reduced dose of PTCy maintain the same level of protection against Graft Versus Host Disease (GvHD) as the standard dose of PTCy?
The purpose of this study is to validate the ability of the STRATICYTE™ predictive model to predict the transformation of oral potentially malignant disorders (OPMDs) to oral squamous cell carcinoma (OSCC) in a retrospective cohort of patients who received biopsies.
This is a prospective, multi-center, Phase II study of hematopoietic cell transplantation (HCT) using human leukocyte antigen (HLA)-mismatched unrelated donors (MMUD) for peripheral blood stem cell transplant in adults and bone marrow stem cell transplant in children. Post-transplant cyclophosphamide (PTCy), tacrolimus and mycophenolate mofetil (MMF) will be used for for graft versus host disease (GVHD) prophylaxis. This trial will study how well this treatment works in patients with hematologic malignancies.
Background: Cancer has a major impact in the United States and across the world. In 2015, over 1.5 million new cases of cancer were diagnosed in the U.S. Researchers want to study samples from people with cancer or a pre-malignant condition. They hope to develop more effective treatments. Objective: To better understand the biology of malignancies and why certain cancers respond differently to treatment. Eligibility: Adults at least 18 years old with cancer or a pre-cancerous condition. Design: Participants will be screened with a medical history, physical exam, and blood tests. Their diagnosis will be confirmed by the NCI Laboratory of Pathology. Participants will send tissue blocks or slides from their original tumor biopsy. At least once, participants will have a medical history, physical exam, and blood and urine tests. Participants may have the following tests. They may have them more than once: Apheresis. A needle in one arm removes blood. Blood is run through a machine and the sample cells are taken out. The rest of the blood is returned by a needle in the other arm. Bone marrow aspiration and biopsy. The hipbone will be numbed. A needle will be put into the hipbone. Bone marrow will be taken out through the needle. Piece of cancer tissue taken by a needle and syringe. Computed tomography (CT) scan, magnetic resonance imaging (MRI) and/or positron emission tomography (PET) scan or ultrasound to help locate their tumor. For the scans, they lie in a machine that takes pictures. A small piece of skin removed. Participants will be contacted by phone once a year to find out how they are doing.
The purpose of the study is to evaluate if firefighter exposure to hazardous compounds will increase the incidence of premalignant hematological states which subsequently increases the risk of the development of hematologic malignancies, and potentially other pathophysiological consequences.
BACKGROUND: * A number of important scientific advances can be made through the study of blood, bone marrow, tumor, or other tissue samples from patients with HIV infection, infection with Kaposi s sarcoma associated herpesvirus (KSHV), infection with other oncogenic viruses, or cancer. * This protocol provides a mechanism to affect a variety of such studies. OBJECTIVES: -Acquisition of serum, circulating cells, bone marrow, and tumor or normal tissue samples from participants with HIV infection, KSHV infection, or with cancer. ELIGIBILITY: -Eligibility criteria include age 18 years or older and at least one of the following: Exposure risk to HIV, KSHV, or HPV; HIV seropositive; KSHV seropositive; EBV seropositive; HTLV-1 seropositive; malignancy, Castleman s disease, or skin lesions with appearance of Kaposi s sarcoma; or cervical or anal intraepithelial lesion. DESIGN: * Up to 999 subjects will be enrolled in this study. * Blood samples may be collected at the initial visit, and at follow-up visits. * Other fluids/excretions may be collected (such as urine, saliva, semen, and stool). * Tumor samples may be obtained by fine needle aspirate, by removal of pleural or peritoneal fluid, by skin punch biopsy, or by excisional biopsy, providing the tumor is accessible with minimal risk to the participants. * Specific risks will be described in a separate consent to be obtained at the time of the biopsy. * Samples will be studied in the HIV and AIDS Malignancy Branch, CCR, NCI; laboratories in NCI-Frederick; or those of collaborating investigators.
