Filter by:RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is studying biomarkers in tissue samples from patients with ductal breast carcinoma in situ.
Approximately 65 million Pap smears are performed each year in the United States. The vast majority of results are negative (no abnormality identified) but about 5 percent to 8 percent are reported as abnormal. Most low-grade changes regress spontaneously; only a minority of such lesions would progress to a cancer precursor without treatment. However, there is no way to determine morphologically which patients are at risk or progression. Therefore, both high- and low-grade lesions were often managed with colposcopy and directed biopsy. Epidemiologic, virologic and molecular studies have clearly demonstrated that human papillomavirus (HPV) is the central cause of cervical cancer. The motivation for the Atypical squamous cells of undetermined significance (ASCUS)- Low grade squamous intraepithelial lesion (LSIL) Triage Study (ALTS) trial was to use the information we have gained about the role of HPV to design better treatment and prevention strategies to reduce the burden of cervical cancer and its precursors. ALTS consisted of three management strategies: (1) immediate colposcopy of all women; (2) repeat cytology with colposcopy only if the results show a high grade lesion; and (3) HPV testing and repeat cytology in combination, with referral to colposcopy if either the HPV test is positive or the cytology shows a high grade lesion. Four Clinical Centers University of Alabama, Birmingham Alabama (AL); Magee-Womens Hospital, Pittsburgh Pennsylvania (PA); University of Oklahoma, Oklahoma City OK; and University of Washington, Seattle Washington (WA) enrolled approximately 5,000 women with recent diagnosis of ASCUS or LSIL. Participants were followed at six month intervals for a total of 2 years. The ALTS database and ALTS specimens continue to be a valuable research resource in studies of cervical cancer precursors, screening tests, visual assessment of the cervix and investigation of biomarkers.
The accurate detection and therapy of adenocarcinoma originating from Barrett's oesophagus is challenging as current endoscopic techniques are unreliable for both the detection of high grade intraepithelial neoplasia (HGIN) within Barrett's mucosa and the correct measurement of the dimension of such neoplastic lesions. Confocal laser endomicroscopy (CLE) is a promising technology that could help to close this gap. Relying on first clinical trials of CLE, which showed remarkable results for the detection of Barrett's associated neoplasia, the investigators want to use CLE as targeting tool for endoscopic mucosal resection of HGIN in patients suffering from Barrett's oesophagus. CLE-mapping of neoplastic lesions will be documented and compared to the later performed histological evaluation of the resected specimen. If CLE is passing our challenge this will be another valuable proof of its high potential as reliable new endoscopic technology. Its usage could increase the en-bloc resection rate and decrease the amount of repetitive resections, which would remarkably improve the patients comfort.
This PHRC is centred on the intestinal epithelial dysplasia ( DEI) or " tufting enteropathy " or TE the clinical and histo-pathological descriptions of which are specified well to the digestive plan(shot).
The purpose of this study is to evaluate the diagnostic performance of MRI±biopsy to optimize resection of Ductal Carcinoma In Situ (DCIS) breast cancer.
This randomized phase I trial studies the side effects and the best dose of letrozole in preventing breast cancer in healthy postmenopausal women at high risk for breast cancer. Chemoprevention is the use of drugs to keep breast cancer from forming or coming back. The use of letrozole may keep cancer from forming in healthy postmenopausal women at high risk for breast cancer.
The primary objective of this study is to compare the diagnostic accuracy of Digital Breast Tomosynthesis (DBT) versus that of Contrast Enhanced Magnetic Resonance Imaging (CEMRI) in determining the size of breast cancer preoperatively. Secondary objectives include: 1. Comparing the operating characteristics of each combined imaging protocol with respect to the reference standard, i.e. histopathologic assessment, of additional non-index lesions. 2. Comparison of re-excision rates based on estimated disease extent from adjunctive CEMRI vs. adjunctive DBT. 3. Evaluation of patient satisfaction with regard to the adjunctive modality (DBT vs. CEMRI).
Background: - The Mississippi Delta (which includes the counties along the Mississippi River) is one of the poorest areas in the United States. Women living in the Mississippi Delta have disproportionately high rates of cervical cancer, but they are unlikely to come to clinics except perhaps for giving birth, years before they are diagnosed with cancer. - To improve rates of screening, researchers are attempting an outreach study to see whether under-screened women, if approached by door-to-door recruitment, would get screened by one of two methods (home-based self-collection and testing, or a clinic exam) and which method they would prefer. Objectives: - To assess/measure increased participation of under-screened women living in the Mississippi Delta in cervical cancer screening by offering women the opportunity to get screened by one of two possible community outreach-based cervical cancer screening modalities, self-collection and HPV testing or clinic-based cytology screening, the current standard of care. Eligibility: - Women between 26 and 65 years of age, who are not pregnant currently or in the past 8 weeks, have an intact cervix, have no history of cancer, and have not been screened for cervical cancer in the past 3 years. Design: - Researchers will recruit participants on a door-to-door basis. Researchers will recruit all eligible women within a household. Recruitment will be done only during daylight hours but at the end of the working day to maximize the chances of finding women at home. - Eligible women willing to participate will complete a questionnaire with demographic and medical information. - Participants will be asked to choose the screening method of their preference. If they choose self-collection with HPV testing, they will be given a self-collection kit and asked to perform the self-collection and return the kit within 1 month. Participants who choose to have cytology screening will be provided with the phone number and location of the local health department clinic and will be encouraged to schedule their screening within the following month. - Women who do not complete their participation within 1 month will be considered noncompliant with their chosen intervention. Researchers will re-contact noncompliant women to offer them participation in the study, including permitting them to refuse to participate or to choose the alternative intervention....
Background: - X-ray mammography is the standard method for breast cancer screening. It is a noninvasive test using x-rays to take pictures of breast tissue and detect any abnormalities. - The National Institutes of Health (NIH) Clinical Center has a breast imaging unit that has been accredited by the American College of Radiology. To maintain accreditation, the unit must recruit a certain number of women to have clinical mammograms each year in order to maintain a high level of clinical skills and experience for the radiologists and technologists. Objectives: - To create a state-of-the-art mammography unit at the NIH Clinical Center in order to maintain American College of Radiology accreditation of the NIH breast imaging facility. Eligibility: - Women who are eligible for breast cancer screening because of family cancer history, genetic test results, or previous instances of cancer. Participants may not be pregnant or nursing at the time of the screening. Design: - Participants will provide a brief medical history on arrival at the NIH breast imaging unit. - Each participant will have a standard mammogram performed by a radiology technician. - If the study is normal, participants will be told that no further evaluation will be performed. If the results indicate a need for further imaging or tissue biopsy, participants may elect to return to the care of their primary physician or to receive further follow-up at the NIH Clinical Center.
RATIONALE: Studying quality-of-life in patients having cancer treatment may identify the intermediate- and long-term effects of treatment on patients with cancer PURPOSE: This randomized clinical trial is studying how well an educational intervention works in supporting Hispanic women with stage I, stage II, or stage III breast cancer and their families or caregivers.
