An Observational Research Study to Uncover Subtypes of Cancer Cachexia
Recruiting
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). 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... Read More

Project Talk Trial: Engaging Underserved Communities in End-of-life Conversations
Recruiting
Compared to the general population, individuals from underserved communities are more likely to receive low quality end-of-life care and unwanted, costly and burdensome treatments due in part to a lack of advance care planning (ACP; the process of discussing wishes for end-of-life care with loved ones/clinicians and documenting them in advance directives). This study will use existing, trusted, and respected social networks to evaluate two conversation-based tools intended to engage underserved... Read More

Radiation Therapy With Protons or Photons in Treating Patients With Liver Cancer
Recruiting
This phase III trial studies how well radiation therapy with protons works compared with photons in treating patients with liver cancer. Radiation therapy, such as photon therapy, uses high energy x-rays to send the radiation inside the body to the tumor while proton therapy uses a beam of proton particles. Proton therapy can stop shortly after penetrating through the tumor and may cause less damage to the surrounding healthy organs and result in better survival in patients with liver cancer.
