This study collects blood and tissue samples from patients with cancer and without cancer to evaluate tests for early cancer detection. Collecting and storing samples of blood and tissue from patients with and without cancer to study in the laboratory may help researchers develop tests for the early detection of cancers.

This study examines the side effects that occur from receiving immunotherapy (immune checkpoint inhibitor) in patients with malignant solid tumors. Immunotherapy is the type of treatment that helps your immune system fight cancer. In the future, this information may help participants and their doctors make better decisions about cancer treatments.

This phase III cluster randomized trial compares the effect of geriatric evaluation and management with survivorship health education (GEMS) to usual care on patient-reported physical function in older survivors of cancer. Survivorship care for older adults of cancer usually consists of getting advice from their doctor. This advice may include how to do their daily activities, so they are less tired or how to manage multiple diseases, or long-term side effects from treatment. GEMS may help improve the physical ability to perform activities of daily living, mental well-being, and memory in older survivors of cancer after chemotherapy. This study may help doctors learn if including GEMS in their practices improves physical, mental and memory functions in their patients. The study may also help to understand how such care affects cancer patients and their caregivers' quality of life.

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 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.

To determine whether an Internet-based pain coping skills program plus enhanced usual care, compared to enhanced usual care alone, yields significant improvements in the co-primary outcomes of pain severity (as measured by the Brief Pain Inventory (BPI)) and pain interference (also measured by the BPI) from baseline to the post-intervention assessment for cancer survivors with persistent pain.
