This study is an observational retrospective/ prospective study with diagnosed low/intermediate risk (no-surgery) \& high risk (surgery) prostate cancer that are eligible and willing to undergo standard of care (SOC) assessment, annually along with biopsies, bio-fluid collection. Participants will obtain genomic and histological evaluation on their biopsied samples. Study follows SOC collection with additional body fluid collection (blood, urine). Biopsy/surgery will not require additional sample collection
Investigators will test the effectiveness of adaptive strategies on timely adoption of cervical cancer treatment in Botswana using a pragmatic trial design.
Background: Prostate cancer (PCa) is one of the most common cancers in American men; it is a leading cause of death. Men of African ancestry have a higher rate of prostate cancer, and a higher likelihood of death, compared to men of European ancestry. The reasons for these higher rates are not known; they may include genetic and environmental factors. Better screening methods are needed. Objective: To test an imaging technology called multiparametric magnetic resonance imaging (mpMRI) for detecting prostate cancer in men of African ancestry. Eligibility: Men of African ancestry aged 35 years or older with prostate cancer and/or a strong family history of prostate cancer. Design: Participants will be screened. They will have a physical exam with blood and urine tests. Participants will have an mpMRI. They will lie on a narrow bed that slides into a large cylinder. They will lie still for about 45 minutes. They will hear loud noises during the scan; they may wear earplugs or headphones to muffle the sound. Some participants may have a dye injected into a vein. If the scan indicates participants risk of prostate cancer is medium or high, they will have a biopsy: The area will be numbed, and samples of tissue will be removed from the prostate. The biopsy will be done within 6 months. If the scan indicates participants risk of prostate cancer is low, they will not have a biopsy. All participants will be followed for 5 years. They and/or their local doctors will be contacted once a year for follow-up. Additional mpMRIs may be recommended.
Doctors leading this study hope to learn about a software that researchers at the University of Chicago have developed to help analyze radiographic images (different techniques for taking images that allow doctors to visualize the body's internal structures) of the prostate. Participation in this research will last about 12 months. There is a one-time MRI and 1-2 biopsies and then the investigator would like to follow the participant's progress.
The purpose of this study is to train Nigerian radiologists to perform ultrasound-guided breast biopsies. Researchers will use mHealth devices to create a sustainable and practical way of training radiologists in Nigeria to perform and clinically implement US-guided breast biopsies into their practice.
The objective is to better identify suspicious breast lesions that need to be biopsied for malignancy in women currently recommended for biopsy. The long-term goal is to reduce unnecessary biopsies and increase biopsy yield. To do this, the investigators have developed an innovative way to use FDA-approved breast imaging protocols to acquire multispectral images to measure the composition of suspicious breast lesions. The central hypothesis is that breast tissue composition in combination with analysis of morphological and textural tissue characteristics on digital breast tomosynthesis (DBT) imaging will yield significantly higher breast cancer specificity than conventional interpretation of DBT alone.
This phase III trial investigates if perflutren lipid microspheres with ultrasound can be used to diagnose prostate cancer non-invasively. Definity (perflutren lipid microspheres) is an ultrasound contrast agent that is typically used for ultrasound bubble studies that involve the heart. Definity appears on ultrasound images as tiny gas-filled microbubbles. These microbubbles are about the size of a red blood cell and do not stay in a patient's body for more than several minutes, where they are excreted from the lungs and exhaled back into the air when breathing. Definity may enhance ultrasound images of the prostate and help doctors identify prostate cancer on ultrasound images.
Digital single-operator cholangioscopy (DSOC) findings achieve high diagnostic accuracy for neoplastic bile duct lesions. To date, there is not a universally accepted DSOC classification. Endoscopists' Intra and interobserver agreements vary widely. Cholangiocarcinoma (CCA) assessment through artificial intelligence (AI) tools is almost exclusively for intrahepatic CCA (iCCA). Therefore, more AI tools are necessary for assessing extrahepatic neoplastic bile duct lesions. In Ecuador, the investigators have recently proposed an AI model to classify bile duct lesions during real-time DSOC, which accurately detected malignancy patterns. This research pursues a clinical validation of our AI model for distinguishing between neoplastic and non-neoplastic bile duct lesions, compared with high DSOC experienced endoscopists.
This study identifies patient-important outcome measures and develops a survey that assesses the impact of nutritional interventions among cancer patients. Currently, data on the impact of medically tailored meals on outcomes that are meaningful to patients, providers, and payers are limited. For this reason, access to medically tailored meals as a covered benefit for cancer patients is limited. Thus, there is a need to explore the efficacy of nutritional interventions among this population. This study identifies outcome measures for nutritional interventions that are meaningful to patients and providers.
This clinical trial examines the acceptability and effect of a parenting support intervention for families coping with solid tumor that has spread to other places in the body (metastatic) or has come back (recurrent). Parenting support program may help to reduce common parenting concerns, improve communication between parents and children about cancer, and improve the overall psychological wellbeing of parents.
The purpose of this pilot study is to examine, in an innovative setting, the potential for a lung cancer diagnosis in a loved one to represent a teachable moment for smoking cessation in family members or caregivers who are current smokers. The researchers will identify the willingness and preferred modality for smoking cessation among family members/caregivers in this setting. The researchers will estimate abstinence rates at 4, 8, 12, and 24 weeks..
Cancer patients will be randomly shown one of 18 emotional support messages created by the research team that differ based on how much of the message consists of positive statements and how much consists of negative statements. The messages with negative statements also differ based on whether the negative statements occur at the start or end of the message. After viewing the message, participants have the opportunity to rate the effectiveness of the message, to what extent the message made them feel better, and to what extent the message affects how they view the message provider as a useful source of emotional support.
This pilot early phase I trial studies how well real-time optical biopsy works in improving lung cancer diagnosis in patients undergoing lung biopsy. Real-time optical biopsy using confocal microscopy may improve the ability of physicians to diagnose lung cancer and accurately differentiate cancerous and benign lesions found during computed tomography screening.
The objective of this study is to follow the treatment options offered to pregnant women diagnosed with cancer and study the impact that their treatment or delay of treatment has on their own health and that of their children.
This is a cross sectional study to examine the relationship between serum calcium and PTHrP and serum PSA in men referred for prostate biopsy at Wake Forest University.
Recently, targeted next generation sequencing (NGS) platforms have been introduced that allow inexpensive testing for hundreds of mutational hotspots at the same time. A number of additional mutational markers in thyroid cancer have been identified. Highly promising markers associated with tumor prognosis have also been found. This multi-institutional study aims to validate the diagnostic use of mutational markers in thyroid nodules with indeterminate cytology. The proposed hypothesis is that a broad NGS-based genotyping of thyroid nodules using a large panel of mutational markers applied to thyroid FNA samples can provide an accurate cancer risk stratification in thyroid nodules. The performance of the panel will be tested in a multi-institutional double-blind prospective study of FNA samples from thyroid nodules with indeterminate cytology and available surgical outcome
The goal of this clinical research study is to test the use of a minimally invasive multimodality image-guided (MIMIG) intervention system used for performing a lung biopsy. The safety of the MIMIG intervention system will also be studied.
An imaging method has been developed that uses near infrared light as an adjunct to ultrasound for better diagnosis and for monitoring tumor response. This study will use a new, non-invasive way to evaluate breast lumps using a low power light source \& ultrasound to see if breast lumps are benign or cancerous. This study will also evaluate if this new technique might be useful in assessing response to chemotherapy.
This is a prospective single center trial to examine the rates of cancer diagnosis when using computerized software to target suspicious lesions within the prostate identified on mpMRI. The primary evaluation involves comparing the rate of cancer diagnosis when using software-based MRI-Ultrasound image fusion guided biopsy to sample mpMRI findings to the use of visual guided biopsy (cognitive or mental targeting) of the same target. The hypothesis being tested is that fusion guided biopsy will increase detection prostate cancer within mpMRI findings as compared to visual guided biopsy of these areas
Background: - A health event can be a powerful motivator for abrupt behavior changes. For instance, many people who smoke stop after having a heart attack or being diagnosed with cancer. A relative s health event may have a similar effect. For instance, smokers may try to quit after learning that a parent or sibling has lung cancer. Researchers want to study relatives of people with lung cancer to see how the relative s diagnosis affects a person s willingness to quit smoking or have genetic testing. Objectives: - To study the impact of a relative s lung cancer diagnosis on a person s approach to genetic testing and smoking cessation services. Eligibility: - Current smokers between 18 and 55 years of age who are close blood relatives of people being treated for lung cancer. Design: * Participants will be recruited through telephone surveys. Participants will log on to a password-protected website. The site has two educational sessions and three surveys to complete. * Participants will also be offered free genetic testing. The test will see whether they have a gene that can reduce the effectiveness of some cancer treatment drugs. Those who agree to the test will collect a cheek swab sample at home and send the sample in for testing. They will receive the test results through the website. * The surveys will ask about risk perceptions and emotional responses to the relative s diagnosis. They will also ask about smoking history, motivation to quit, and reactions to information about smoking and genetic risk. * All participants will be able to receive free smoking cessation services. * Six months after completing the surveys, participants will have a follow-up phone call. The call will ask whether participants used the smoking cessation services.
This study will investigate the usefulness of an optical probe in the differentiation of thyroid cancer from normal thyroid tissue in a thyroidectomy specimen.
Many missed and delayed cancer diagnoses result from breakdowns in communication and coordination of abnormal findings suspicious for cancer, which often first emerge in the primary care setting. Delays in the follow-up of abnormal test results persist despite the reliable delivery of test results through the electronic health record. This intervention is the final study in a three-phase project that will develop and test an innovative automated surveillance intervention to improve timely diagnosis and follow-up of five common cancers in primary care practice. The investigators hypothesize that the median time in days from diagnostic clue to follow-up action (e.g. time to colonoscopy examination after am abnormal colon-related test) will be significantly less in the intervention arm than in usual care. The investigators also hypothesize that the proportion of patients receiving appropriate and timely follow-up care will be significantly higher in the intervention arm than in usual care.
Social comparisons may function as a coping strategy, but their role in coping and quality of life has not been well characterized. The purpose of the current study is to investigate the relationships between cognitive appraisals; coping strategies; social comparisons; and quality of life among men with prostate cancer. The conceptual framework for this study is drawn from Festinger s Social Comparison Theory, Lazarus and Folkman s Transactional Model of Stress and Coping, and Mishel s Uncertainty in Illness Theory. A cancer diagnosis is accompanied by uncertainty about how cancer will affect one s life. Theory and empirical data suggest that in conditions of uncertainty, coping affects adjustment to a condition. Social comparisons have been postulated to be more prevalent in uncertain situations. Because little is known about how social comparisons operate, participants in this study will be recruited exclusively from prostate cancer support groups. Support groups provide a context in which individuals are likely to make social comparisons and to be cognizant of these comparisons. Prostate cancer provides a model of a common, chronic condition with complex etiology. Prostate cancer treatment may cause sexual, urinary, and bowel side effects, which may affect patients quality of life and elicit attempts to cope. One way of managing the prostate cancer experience may be to compare oneself to others who are doing better or worse than oneself on relevant dimensions. The interpretation of social comparisons may positively or negatively affect one s perceived quality of life. There have been no studies among prostate cancer patients that have quantitatively measured the use of social comparisons. There is also a paucity of research in this population regarding the predictors of coping strategies and the predictors of quality of life across multiple domains. This study will use a cross-sectional, mixed methods survey to investigate relationships between cognitive appraisals, coping, and quality of life and to qualitatively explore social comparisons among men with prostate cancer. Participants may complete the survey on paper or online. The primary outcomes are the use of coping strategies, including social comparisons, and quality of life. Individuals with a personal or family history of prostate cancer are currently seen by genetic counselors as part of research studies investigating the genetic basis of prostate cancer. If relationships are demonstrated between the social comparisons and quality of life, genetic counselors may want to assess patients social comparisons to evaluate how patients are coping with their condition.
The study is designed to determine if high doses of intravenous ascorbic acid (vitamin C) can be effective in managing solid tumor diseases. Secondary goals are determination of any palliative effects and improvement of quality of life of patients.
The purpose of the study is to compare the effects of one exercise/counseling protocol with usual care on long term exercise adherence and on changes in health related outcomes after breast cancer diagnosis.
RATIONALE: Gathering information about timely diagnosis in African American and Caucasian patients with newly diagnosed colorectal cancer may help doctors learn more about factors that influence a diagnosis and plan the best treatment. PURPOSE: This phase I trial is studying differences in timely cancer diagnosis in African American patients and in Caucasian patients with newly diagnosed colorectal cancer.
The purpose of this study is to develop computer programs to assist radiologists in finding breast cancer on mammograms and to compare the computer's accuracy of detecting cancers on direct digital and film mammograms.
This study will investigate how patients are informed of their cancer diagnosis or recurrence and will explore their experience in learning about the diagnosis. Specifically, it will: * Distinguish methods of telling the diagnosis and identify its relationship to the type of cancer. * Determine if the way a patient is informed of their diagnosis is associated with their level of satisfaction with the method of being informed. * Identify who informs the patient of their diagnosis.. * Determine patient satisfaction with their diagnostic consult. * Identify indicators of satisfaction with the diagnostic consultation. Patients 18 years of age or older who are enrolled in or being screened for enrollment in a phase I, II or III clinical trial in the National Cancer Institute's Medical Oncology, Metabolism, Surgery or Neuro-Oncology branch may be eligible for this study. Participants complete a 15-minute questionnaire that includes questions related to the how they were informed of their cancer diagnosis.
