Filter by:RATIONALE: Doctors use a swab to collect cell samples when testing for anal cancer and human papillomavirus. It is not yet known which type of swab is more effective in collecting cell samples for anal Pap tests and human papillomavirus tests in men who have sex with men. PURPOSE: This clinical trial is comparing two types of swabs in collecting cell samples for anal Pap tests and human papillomavirus tests in men who have sex with men.
Background: - HIV-positive men who have sex with men (MSM) have rates of anal cancer that approach those of cervical cancer in women. However, unlike cervical cancer, there is no current recommended method of screening that could be used to detect anal precancerous lesions for the prevention of anal cancer in HIV-positive MSM. - Infections by human papillomavirus (HPV) are the likely cause of cervical and anal precancer and cancer. Detecting the presence of HPV or related biomarkers has helped to identify women who may be at increased risk of cervical cancer; researchers believe that early detection of HPV or related biomarkers in MSM may be useful for anal cancer screening. Objectives: - To evaluate the effectiveness of various tests to detect cancer-causing HPV in HIV-positive men who have sex with men. Eligibility: - HIV-positive MSM that are interested in receiving anal screening for precancer Design: - HIV-positive MSM will respond to a self-administered risk factor questionnaire, and will undergo a physical exam and a high-resolution anoscopy at the participating clinic. - The clinician will then collect to anal Pap specimens from each subject for research on HPV and related biomarkers. - Participants will be followed annually for 2 years to collect additional health data for research follow-up.
RATIONALE: Gathering information about patients' quality of life during radiation therapy for cancer may help doctors plan the best treatment. PURPOSE: This randomized clinical trial is studying quality of life in patients undergoing radiation therapy for primary lung cancer, head and neck cancer, or gastrointestinal cancer.
Patient will have radiation to treat the cancer. This treatment can make the vagina both narrower and shorter. That can cause two problems. It can make it harder for the doctor to do a pelvic exam during a follow-up visits. And, it can make sexual intercourse uncomfortable. We tell women to use a vaginal dilator after radiation to the pelvis. This is standard education. We do not routinely ask women how they do with it. We are doing this study to see if using the dilator as we instruct will help the vagina stretch. The patient will have an examine of the vagina before the start of radiation. We will see what size dilator can fit. The goal of this study is to have the patient be able to use that size dilator within six months after radiation.
The study compares two patient setups (Standard Prone vs. Genital Drop Technique) with identical radiation treatment technique and parameters. After the two setups have been planned, the treating faculty reviews the setups and will choose the setup he feels that will give the patient improved dosimetry to the local regions and hopefully reduce toxicity and improve treatment tolerability.
To determine whether using a radiolabelled analog of 5-FU, [18F]-5-fluorouracil, for PET/CT imaging can visually demonstrate differential chemotherapy delivery to known tumor sites before and after administration of bevacizumab and determine the optimal timing of bevacizumab administration to maximize the chemotherapy delivery into the tumor for improved cancer treatment.
RATIONALE: Drugs used in chemotherapy, such as irinotecan, fluorouracil, and leucovorin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of irinotecan when given together with fluorouracil and leucovorin in treating patients with advanced gastrointestinal cancer.
RATIONALE: High-grade squamous intraepithelial lesions of the skin near the anus are caused by the human papillomavirus (HPV). Antiviral drugs,, such as cidofovir, act against viruses and may stop these lesions from becoming cancer. PURPOSE: This phase II trial is studying the side effects and how well topical cidofovir works in treating HIV-infected patients with high-grade squamous intraepithelial lesions of the skin near the anus.
Primary Objectives: - To determine the feasibility of a study that would describe changes of certain circulating inflammatory cytokines (interleukin-1, 6, 8, 10, 12, and tumor necrosis factor-alpha [TNF] and symptoms related to chemoradiation therapy (pre-therapy, during therapy and up to 3 months post-therapy) among patients with lung, esophageal, gastric, colorectal and anal cancer. - To determine the feasibility of studying neurocognitive function in patients with non-small cell lung cancer (NSCLC) at presentation and during chemoradiation therapy to determine the prevalence, severity, and pattern of cognitive symptoms.
This study is designed to identify barriers that prevent men who have sex with men from receiving doctor-recommended annual follow-up screenings for anal cancer. Men who are at the highest risk for developing anal cancer will be asked to complete a brief questionnaire (either via telephone or in writing). The questionnaire is designed to identify potential barriers to care-seeking behavior including, relationship status, financial constraints, highest level of education and knowledge about anal cancer and its precursors. The men who agree to participate in the study will then be organized into groups based on their history of coming in for follow-up screening visits after learning that they are at higher risk for developing anal cancer. These groups include 1) men that have come in for regular screening visits (at least once per year), 2) men who came in once and were then lost to follow-up, 3) men who came in for more than one screening visit and were then lost to follow-up, and 4) men who were previously lost to follow-up and then began coming in for screening again. By comparing the men's responses across the different groups, we hope to uncover key barriers and drivers to follow-up screenings for anal cancer. The goal of this study is to evaluate the differences in questionnaire responses across cohorts that may impact care-seeking behavior. We hypothesize that: - Patients who regularly comply with annual follow-up screening visits score higher on questions assessing knowledge of HPV and anal cancer. - Men in stable relationships are more likely to comply with annual screening visit recommendations. - Men who are educated by their primary care physicians about the importance of anal cancer screenings have higher screening rates.
