This clinical trial tests the impact of a culturally-tailored home-based physical activity program on physical fitness in Hispanic or Latino/Latina adolescent and young adult (AYA) childhood cancer survivors. After treatment for cancer, some AYA survivors experience long-term effects from the cancer and its treatment including weight gain, fatigue and decreased physical fitness. Hispanic or Latino/Latina survivors may have a higher risk of these effects compared to non-Hispanics. Regular physical activity helps maintain healthy weight, energy levels and overall health. Participating in a culturally-tailored home-based physical activity program may help increase physical activity in Hispanic or Latino/Latina AYA childhood cancer survivors.

A Study Testing the Combination of Dasatinib or Imatinib to Chemotherapy Treatment With Blinatumoma1

This pilot trial assesses the effect of the combination of blinatumomab with dasatinib or imatinib and standard chemotherapy for treating patients with Philadelphia chromosome positive (Ph+) or ABL-class Philadelphia chromosome-like (Ph-like) B-Cell acute lymphoblastic leukemia (B-ALL). Blinatumoma1 expand

This pilot trial assesses the effect of the combination of blinatumomab with dasatinib or imatinib and standard chemotherapy for treating patients with Philadelphia chromosome positive (Ph+) or ABL-class Philadelphia chromosome-like (Ph-like) B-Cell acute lymphoblastic leukemia (B-ALL). Blinatumomab is a bispecific antibody that binds to two different proteins-one on the surface of cancer cells and one on the surface of cells in the immune system. An antibody is a protein made by the immune system to help fight infections and other harmful processes/cells/molecules. Blinatumomab may bind to the cancer cell and a T cell (which plays a key role in the immune system's fighting response) at the same time. Blinatumomab may strengthen the immune system's ability to fight cancer cells by activating the body's own immune cells to destroy the tumor. Dasatinib and imatinib are in a class of medications called tyrosine kinase inhibitors. They work by blocking the action of an abnormal protein that signals cancer cells to multiply, which may help keep cancer cells from growing. Giving blinatumomab and dasatinib or imatinib in combination with standard chemotherapy may work better in treating patients with Ph+ or Ph-like ABL-class B-ALL than dasatinib or imatinib with chemotherapy.

The goal of this study is to learn if a decision aid (DA) website helps people with thyroid cancer make informed decisions about radioactive iodine (RAI) treatment. The main questions it aims to answer are: - Does the decision aid help participants understand the risks and benefits of RAI treatment? - Does it help participants make choices that reflect what matters most to them? - How does the decision aid compare to usual care in supporting patients through this decision? Participants who have been recently diagnosed with intermediate-risk differentiated thyroid cancer (DTC) will be randomly assigned to one of two groups. One group will receive a special decision aid website. This site includes detailed information about RAI, short videos, drop-down menus with extra details, exercises to help clarify values, and tools to help patients prepare questions for their doctor. The other group will receive the American Cancer Society (ACS) website. This site gives basic information about RAI but does not include interactive tools and is not specific to intermediate-risk thyroid cancer. Follow up surveys will be sent to the participants periodically, first at the start of the study, and again at 1 week, 4 weeks, and 6 months later. Researchers will compare how the two groups differ in making informed decisions. The decision aid is meant to support, not replace, a conversation with the medical team. Doctor recommendations remain an important part of treatment decisions.

This phase III trial compares the effect of adding radiation therapy to usual care on the occurrence of bone-related complications in cancer patients with high-risk bone metastases that are not causing symptoms (asymptomatic). High-risk bone metastases are defined by their location (including hip, shoulder, long bones, and certain levels of the spine), or size (2 cm or larger). These bone metastases appear to be at higher risk of complications such as fracture, spinal cord compression, and/or pain warranting surgery or radiation treatment. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. The total dose of radiation can be delivered in a single day or divided in smaller doses for up to 5 days of total treatment. Usual care for asymptomatic bone metastases may include drugs that prevent bone loss, in addition to the treatment for the primary cancer or observation (which means no treatment until symptoms appear). Evidence has shown that preventative radiation therapy may be effective in lowering the number of bone metastases-related complications, however, it is not known if this approach is superior to usual care. Adding radiation therapy to usual care may be more effective in preventing bone-related complications than usual care alone in cancer patients with asymptomatic high-risk bone metastases.

This study evaluates cancer-related weight and muscle mass loss, symptoms, and physical function (cachexia) in patients undergoing treatment for colorectal, lung, or pancreatic cancer that cannot be removed by surgery (unresectable) or is stage IV. Patients with these cancer types are at risk for developing cancer cachexia (CC), which is defined as weight loss, muscle loss, and fat loss due to cancer. CC has been associated with reduced physical performance, impaired quality of life, and poorer survival. Many studies that have evaluated treatments for cancer-related weight and muscle loss have aimed to treat all patients with weight loss exactly the same and, unfortunately, have not been successful. Like different cancer types, weight and muscle loss related to cancer may have different causes in different individuals and the best treatment strategy for this condition may not be a one-size-fits-all approach. Information gathered from this study may help researchers develop new diagnostic criteria for CC and design better treatments and clinical trials for cancer-related weight and muscle loss in the future to improve the quality of life in patients with advanced colorectal, lung, or pancreatic cancer.

Recent Veterans of the Afghanistan and Iraq conflicts are presenting in VA care with high rates of posttraumatic stress disorder (PTSD), depression, anxiety, and substance use disorders. Difficulties with social relationships and community reintegration are common functional impairments with these disorders. VA is transforming to a Whole Health, patient-centered system of care that will address these issues as part of health care. In a previous study, Omnis Salutis (OS) was developed with Veteran and clinician input. OS is a three-session intervention in which Veterans learn about Whole Health and practice communicating their health mission to providers and social supports. OS was shown feasible to deliver, acceptable to Veterans, and preliminarily effective at improving physical, mental, and social functioning. This study will use a large, multisite randomized controlled trial to test the impact of OS on Veterans' social and physical functioning and Veteran engagement in mental health care. Results will support broad delivery of OS throughout the VA.
