Filter by:This culture system utilizes the special affinity difference of biomedical material coating for different cells to achieve the effect of isolating cancer cells from the blood sample. The coating of the system has the characteristic that to make the WBCs adhesion, but the cancer cells in the blood sample suspend in the culture medium, which achieves the effect of separating cancer cells from the blood. The supernatant with the cancer cells can further be isolated from the cultural system for related analysis and detection to achieve early diagnosis and screening.
The primary purpose of this study is to determine the impact of maximizing patient and primary care provider (PCP) activation on breast cancer surveillance rates among women previously treated with chest radiotherapy (RT) for a childhood cancer. This is an 18-month, 3-arm randomized controlled trial using a smartphone intervention with data being collected at baseline and 18-months through patient and provider surveys and medical record review. Eligible women treated for a childhood cancer with chest RT will be randomly sampled from the Childhood Cancer Survivor Study (CCSS) and randomly selected to one of three groups: control, patient activation (PA) using a smartphone-based intervention, or patient activation + primary care provider activation (PA+PCP) which will include physician materials about breast cancer risk in this population along with guidelines for breast cancer surveillance. Participants in all groups will receive mailed targeted print materials as an educational resource about their previous chest radiation and breast cancer screening recommendations. The primary outcome is a medical record confirmed breast MRI and mammogram with the goal of increasing the rate of women completing the national guideline-based recommended combination of breast MRI and mammogram. This study will test the hypothesis that women in the PA and PA+PCP groups will have significantly higher rates of breast cancer surveillance (breast MRI and mammogram) than women in the control group. In addition, the hypothesis that women in the PA+PCP group will have significantly higher rates of breast cancer surveillance than women in the PA group will also be tested.
The DENACAPST programme represents an important initiative to provide near nation-wide roll-out of an important cancer surveillance program for childhood cancer survivors. The program is based on internationally recognized standards in cancer surveillance, which were developed by the International Guideline Harmonization Group (IGHG) with support of all relevant stakeholders in cancer survivorship research and clinical work in Europe, Canada and the United States and recognized French recommendations about breast screening for women at high risk of cancer. With this programme, French centers organized themselves to provide to childhood cancer survivors adequate medical attention, which includes close medical surveillance for breast/thyroid cancer where appropriate, based on adequate risk stratification. The aim of the study is to analyze if the recommendations about breast and thyroid cancer screening are followed in this population and secondly to provide more informations about these second cancers and about the screening.
Family doctors can play a critical role in successfully arranging cancer screening tests to occur, especially if they know which patients are due for these tests. However, they don't always interact with or take advantage of registry data to this end. For example, in Ontario, the Screening Activity Report provides exactly this information to family doctors, helping them identify their patients who are overdue for screening. Unfortunately, less than half of family doctors regularly use the Screening Activity Report even though they get monthly email reminders. One possible reason is that the reminders they receive are not designed to compel action. They are easy for family doctors to miss or dismiss. This study will compare multiple different ways of designing the reminders. The different versions of the email are tested in a 2^3 factorial trial testing three behaviour change techniques to see which ones will lead to more family physicians interacting with the Screening Activity Report and at increasing the number of patients that get all the appropriate screening tests for cervical, breast, and/or colon cancer.
This study aims to assess the effectiveness of a stepwise approach, with increasing complexity and cost, to improve adherence to organized cervical cancer screening: step 1a - customized text message invitation; step 1b - customized automatic phone call invitation; step 2 - secretary phone call; step 3 - health professionals face-to-face appointment. A population-based randomized controlled trial will be implemented in Portuguese urban and rural areas. Women eligible for cervical cancer screening will be randomized (1:1) to intervention and control. In the intervention group, women will be invited for screening through text messages, automatic phone calls, manual phone calls and health professional appointments, to be applied sequentially to participants remaining non-adherent after each step. Control will be the standard of care (invitation by written letter). As primary objectives, we intend to test the superiority of interventions based on step 1 (1a+1b) and multistage interventions based on steps 1 and 2 and steps 1 to 3, based on intention-to-treat analyses.
The primary objective of this study is to assess the effect of the decision aid on measures of decision-making such as knowledge, screening attitudes, decisional conflict, and screening intent.
This randomized trial aims to understand how effective a reminder letter is compared to a reminder phone call in improving breast, cervical and colorectal cancer screening rates and reducing screening disparities.
The purpose of this research study is to explore ways to improve appropriate colorectal cancer (CRC) screening in the elderly by attempting to target screening in those most likely to benefit and avoiding screening in those least likely to benefit.
Study objectives: to evaluate the effects of information about benefits and risks of mammography screening on participants in terms of knowledge, attitude, rates of uptake, fear of cancer, anxiety, and conflict decision. Study hypothesis: information about benefit and risks of mammography screening increases the women´s knowledge of it; allows women to make an informed decision on whether to stop or continue the screening program, changing the actual participation rate; anxiety and fear are not increased. Design: randomized controlled clinical trial with non-pharmacological intervention. Subjects and setting of study: women referred to mammography screening in the District Bay of Cádiz-La Janda. Interventions: random assignment of women in two arms according to the information provided. Control arm is the standard information; it consists of receiving information normally provided to women attending the screening program for breast cancer. Intervention arm is the experimental information and consists of receiving accurate verbal and written information about the benefits and real risks of mammography screening programs by a physician investigator. Determinations: knowledge, attitude, rates of uptake, fear of cancer, anxiety, and conflict decision.
