Cancer-related fatigue: scientific progress has been made in 40 years

Cancer-related fatigue (CRF) is a distressing, persistent symptom that is experienced by survivors during and after treatment. Unsurprisingly, many early CRF studies were conducted by nurses. These studies included a look at patients receiving localized radiation treatment (Haylock & Hart, 1979); an exploration of fatigue as a conceptual approach to a clinical problem (Aistars, 1987); the development of a nursing theory focused on fatigue mechanisms (Piper, Lindsey, & Dodd, 1987); an examination of fatigue mechanisms (St Pierre, Kasper, & Lindsey, 1992), as well as of fatigue in advanced cancer (Bruera & MacDonald, 1988) and in non-small cell lung cancer (Sarna, 1993); and a description of fatigue and potential nursing interventions (Nail & King, 1987). Winningham et al. (1994) wrote a state-of-the-science article about fatigue in the cancer experience for the Oncology Nursing Forum, and Mock et al. (1997) was one of the first to conduct an exercise study regarding the effects of exercise on fatigue, physical functioning, and emotional distress during radiation therapy for breast cancer. Nurse scholars from the 1970s-2000s were pivotal in advancing the science of fatigue in various cancers and have provided a scientific foundation for those four decades.
