Many conditions that would not be considered normal in a younger population are routinely accepted in older people as a part of so-called "normal" aging. Among these conditions are many chronic and debilitating conditions such as chronic pain, insomnia, weakness, fatigue, and anemia. This article reviews current evidence regarding the relationships among age, fatigue, weakness, anemia, and erythropoiesis. Anemia in the elderly is important because it can lead to weakness, fatigue, limitations in activity, and may increase cardiovascular risk. Recent studies of the effect of erythropoietin in an aging population support the hypothesis that anemia is associated with pathologic factors and not with normal aging. While older individuals admitted to hospitals are more likely to be anemic, these same individuals have a bone marrow mass and numbers of cultured progenitor cells that are similar to that of the younger population; therefore, the predicted response to erythropoietin, and thus the function of the bone marrow and cellular progenitors, is maintained. Thus, we can conclude that anemia is a correctable pathologic finding in elderly people. A number of studies have shown a strong relationship between fatigue and anemia, but few studies investigate to what degree age is a factor in weakness and fatigue. In a study of 375 anemic cancer patients with a median age of 61 years, age as a covariate in multiple linear regression analysis failed to reach significance for most measures of function and quality of life (QOL), including measures of energy, activities, mental health, general cancer-related QOL, and overall QOL. Additional analysis suggests that other factors, including cancer progression, hemoglobin change, and baseline hemoglobin levels, are much more important in determining change in functional and quality-of-life scores. In another set of 2,000 cancer patients and 1,000 controls, cancer patients experienced significantly more fatigue compared with controls. There was no correlation between cancer patient age and fatigue, while in controls the cohort aged 65 or more reported more fatigue than did younger subjects. Finally, measurement of QOL in the general population demonstrated, for both the Short-Form 36 and Functional Assessment of Cancer Therapy - Anemia questionnaires, that age alone is not significantly correlated with QOL. We suggest that chronic conditions such as fatigue and anemia are no more "normal" in an aging population than in a general population, and that all patients with chronic conditions be adequately treated and counseled for their condition.

Advanced cancer treatment is a huge challenge and new ideas and strategies are required. Hydrogen exerts antioxidant and anti-inflammatory effects that may be exploited to control cancer, the occurrence and progression of which is closely related to peroxidation and inflammation. We conducted a prospective follow-up study of 82 patients with stage III and IV cancer treated with hydrogen inhalation using the "real world evidence" method. After 3-46 months of follow-up, 12 patients died in stage IV. After 4 weeks of hydrogen inhalation, patients reported significant improvements in fatigue, insomnia, anorexia and pain. Furthermore, 41.5% of patients had improved physical status, with the best effect achieved in lung cancer patients and the poorest in patients with pancreatic and gynecologic cancers. Of the 58 cases with one or more abnormal tumor markers elevated, the markers were decreased at 13-45 days (median 23 days) after hydrogen inhalation in 36.2%. The greatest marker decrease was in achieved lung cancer and the lowest in pancreatic and hepatic malignancies. Of the 80 cases with tumors visible in imaging, the total disease control rate was 57.5%, with complete and partial remission appearing at 21-80 days (median 55 days) after hydrogen inhalation. The disease control rate was significantly higher in stage III patients than in stage IV patients (83.0% and 47.7%, respectively), with the lowest disease control rate in pancreatic cancer patients. No hematological toxicity was observed although minor adverse reactions that resolved spontaneously were seen in individual cases. In patients with advanced cancer, inhaled hydrogen can improve patients' quality-of-life and control cancer progression. Hydrogen inhalation is a simple, low-cost treatment with few adverse reactions that warrants further investigation as a strategy for clinical rehabilitation of patients with advanced cancer. The study protocol received ethical approval from the Ethics Committee of Fuda Cancer Hospital of Jinan University on December 7, 2018 (approval number: Fuda20181207).
