Cancer-related fatigue (CRF) is a common complaint for those patients undergoing chemotherapy and/or radiation. I understand that my personal cancer experience may not be universal but I don’t believe that my cancer-related fatigue has ever really healed.
Among the many side effects and complications caused by chemotherapy and radiation, cancer-related fatigue stands out as a significant and often underestimated adverse event. This pervasive exhaustion can have profound effects on a patient’s quality of life, treatment adherence, and overall well-being. This essay aims to shed light on the nature of cancer-related fatigue, its impact on patients, and strategies for its management.
Let me also say that I don’t think that conventional oncology really takes this side effect seriously. I mean what’s an oncologist going to prescribe to the patient who complains that chemo or radiation makes then feel exhausted all the time?
As always, I try not to present a challenge to the cancer survivor without also proposing possible solutions.
Let me begin with specifics about CRF as an adverse event.
Defining Cancer-Related Fatigue
Cancer-related fatigue (CRF) is a distressing, persistent, and subjective sense of physical, emotional, and/or cognitive exhaustion related to cancer or cancer treatment that is not proportional to recent activity and interferes with normal functioning. Unlike ordinary tiredness, CRF is not relieved by rest and can be overwhelming, debilitating, and long-lasting.
Prevalence and Impact
CRF is one of the most common side effects experienced by cancer patients, affecting up to 90% of individuals undergoing treatment. It transcends cancer types and stages, affecting both those in active treatment and cancer survivors. This persistent fatigue often leads to decreased physical activity, social isolation, and a diminished sense of well-being, affecting a patient’s ability to carry out daily tasks and enjoy life. Additionally, CRF can exacerbate other physical and psychological symptoms, compounding the overall burden on patients.
The exact mechanisms underlying CRF are complex and multifactorial. They may involve a combination of physiological, psychological, and behavioral factors. These include the direct effects of the tumor and its treatment on the body, alterations in hormonal balance, immune system dysregulation, psychological distress, and disrupted sleep patterns. Additionally, comorbid conditions such as anemia, depression, and pain can contribute to the intensity of CRF.
Management and Interventions
Given the multifaceted nature of CRF, a holistic approach to management is crucial. This includes:
Cancer-related fatigue is a pervasive and debilitating adverse event experienced by a significant majority of cancer patients. Understanding its underlying mechanisms and implementing comprehensive management strategies are vital steps in improving the overall quality of life for individuals affected by this condition. By addressing CRF with a multidisciplinary approach that encompasses pharmacological, psychosocial, and lifestyle interventions, healthcare providers can offer more effective and holistic care to cancer patients, ultimately aiding in their journey towards recovery and improved well-being.

“Cancer-related fatigue (CRF) is one of the most common complications in patients with multiple cancer types and severely affects patients’ quality of life. However, there have only been single symptom-relieving adjuvant therapies but no effective pharmaceutical treatment for the CRF syndrome…
DCA preserved physical function in mice with late-stage tumors by reducing circulating lactate concentrations. In vivo liquid chromatography-mass spectrometry/mass spectrometry studies suggest that DCA treatment may preserve membrane potential, postpone proteolysis, and relieve oxidative stress in muscles of tumor-bearing mice. In all, this study provides evidence for DCA as a novel pharmaceutical treatment to maintain physical function and motivation in murine models of CRF…
NEW & NOTEWORTHY We identify a new metabolic target for cancer-related fatigue, dichloroacetate (DCA). They demonstrate that in mice, DCA preserves physical function and protects against the detrimental effects of cancer treatment by reducing cancer-induced increases in circulating lactate. As DCA is already FDA approved for another indication, these results could be rapidly translated to clinical trials for this condition for which no pharmaceutical therapies exist beyond symptom management.
