Characterizing Fatigue Experienced by Cancer Patients Receiving Primary Treatment and Cancer Survivors

Background: \- Fatigue is a common side effect of cancer and its treatment. Up to 96% of patients with cancer have fatigue. The cause of fatigue in people with cancer or those receiving treatment is poorly understood, making fatigue hard to treat. More research is necessary to understand why cancer patients experience fatigue. Previous research has shown that fatigue may be caused by a number of factors, including problems with the immune system response of the body while undergoing cancer treatment. The researchers of this study are trying to understand how the immune system and other chemicals of the body change while a person receives cancer treatment and how these changes play a role in causing fatigue. The researchers are also interested in how a person s quality of life is affected by fatigue. Objectives: \- To study fatigue in individuals who have cancer, are receiving cancer treatment, or have completed cancer treatment. Eligibility: * Individuals at least 18 years of age. * Receiving cancer treatment, OR completed primary treatment for cancer (e.g., cancer survivors), OR on active surveillance for localized cancer. Design: * This study involves an initial screening visit and up to three outpatient visits. * Participants will be screened with a medical history review (can be done virtually) and blood tests. A physical exam might also occur. * Participants undergoing cancer treatment that has a clear completion date, will have the following visits: * Before the start of treatment. * At the end of treatment. * At least 3 months after treatment ends. * Participants not receiving treatment, are cancer survivors, or undergoing cancer treatment that does not have a clear completion date, will have up to 3 visits: * Before the start of treatment or whenever you begin the study. * At least 3 months after your first visit. * At least 3 months after your second visit. * At each study visit, participants will complete the following tasks (some of the tasks can be done from home or virtually): * Questionnaires about physical activity, fatigue, depression, and quality of life (can be done at home or virtually). * Have blood drawn. * Physical activity device and journals to study how fatigue affects physical activity. * Optional tests: * Computer games testing your memory, attention, and ability to follow directions. * Hand grip strength test to evaluate physical strength. * Treatment will not be provided under this study.

* INCLUSION CRITERIA:

To be included, patients must meet all of the following criteria:

* Medical documentation confirming diagnosis of:

  --Clinically localized or metastatic cancer as determined by diagnostic testing such as cytology and imaging (such as, but not limited to non-metastatic head and neck cancer, lung cancer, breast cancer, renal cancer); OR completed primary treatment for cancer (e.g., cancer survivors) OR on active surveillance for localized cancer;
* Able to provide written informed consent;
* Women and men greater than or equal to 18 years of age;
* NIH employees and staff are eligible to participate.

EXCLUSION CRITERIA:

* Progressive or unstable disease other than cancer of any body system causing clinically significant fatigue (e.g. class IV congestive heart failure, end-stage renal disease, stage IV chronic obstructive pulmonary disease) including patients with

  * Systemic infections (e.g., human immunodeficiency virus \[HIV\], active hepatitis);
  * Documented history of unstable major depression, bipolar disease, psychosis, or alcohol/drug dependence/abuse; requiring hospitalization/institutionalization;
  * Uncorrected hypothyroidism;
  * Untreated anemia;
  * Chronic inflammatory disease (e.g. rheumatoid arthritis, systemic lupus erythematosus).
* Patients regularly taking antipsychotics, and anticonvulsants, since these medications cause significant fatigue.
* NINR employees or subordinates, relatives, and/or co-workers of NINR employees/staff or study investigators.
* Self-report of color-blindness verified by taking the Ishihara card test with scores \>14 (10 minutes) will be an exclusion from the Stroop Test. This card test will be administered only if the patient reports being color blind.
* Severe essential hand tremor or severe hand pain (e.g., severe arthritis or severe carpel tunnel) will be an exclusion from the computerized tests and the skeletal muscle strength test.
* Ongoing medical condition that is deemed by the Principal Investigator to interfere with the conduct or assessments of the study or safety of the participant.
