An Observational Research Study to Uncover Subtypes of Cancer Cachexia
NCT06073431
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

Testing the Effects of Exercise on Chemotherapy-Induced Peripheral Neuropathy
NCT04888988
Recruiting
This phase II trial studies whether using exercise is better than the usual approach for treating chemotherapy-induced peripheral neuropathy (CIPN). CIPN occurs when chemotherapy damages the nerves communicating between the brain, spinal cord, and the rest of the body. The usual approach for treating CIPN is treatment with drugs that help reduce symptoms of other types of neuropathy (for example, from diabetes). However, these drugs do not treat all symptoms of CIPN. Exercise may help to reduce... Read More

Bupropion to Reduce Cancer Related Fatigue in Cancer Survivors
NCT03996265
Recruiting
This phase III trial studies how well bupropion works in reducing cancer related fatigue in cancer survivors. Cancer and its treatment can cause fatigue. Bupropion is a drug that is used to treat depression, as well as to help people quit smoking. It belongs to the family of drugs called antidepressants and works by increasing certain types of activity in the brain. Bupropion may reduce cancer-related fatigue by causing changes in inflammation and stress hormones.
