Introduction: Sarcopenia, defined by reduced muscle strength, mass, and performance, presents a significant challenge in cancer care due to its impact on treatment outcomes, quality of life, and survival. This study aimed to assess its prevalence in newly diagnosed lymphoma patients. Methods: Adults planned for first-line anthracycline-based chemotherapy were enrolled and screened for sarcopenia before treatment. Sarcopenia was defined by the European guidelines (EWGSOP2) using low muscle strength (hand-grip), low muscle mass (DXA), and low physical performance (gait speed). Results: Sixty-nine patients (mean age 57, 19 women) were included. Six patients (9%) had low hand-grip strength, 15 (22%) had low muscle mass, and 4 (6%) demonstrated low gait speed. Two patients met the criteria for sarcopenia, with one having severe sarcopenia. Conclusion: Sarcopenia prevalence was 3%, but 22% had low muscle mass, suggesting muscle strength alone may not be an optimal screening tool for lymphoma patients.

Purpose: This study aims to identify and summarize evidence on the effectiveness of exercise-based interventions on muscle mass, muscle strength, functional performance, aerobic capacity, health-related quality of life (HRQoL), feasibility of the interventions, in patients with malignant lymphoma undergoing chemotherapy. Methods: A systematic search was conducted in six electronic databases and trials registers on November 15, 2023. Peer-reviewed randomized controlled trials (RCTs) comparing exercise intervention with controls/usual care in adults (≥18 years) diagnosed with Hodgkin’s lymphoma and non-Hodgkin’s lymphoma undergoing chemotherapy were considered for inclusion. All study authors were contacted to obtain unpublished subgroup data. Two reviewers independently screened and extracted data and assessed the quality of evidence using the revised Cochrane risk-of-bias tool for randomized trials. Results: Six RCTs published between 2009 and 2021, with 838 participants, were included. Due to clinical heterogeneity, a meta-analysis was not feasible, therefore the results were synthesized narratively. Exercise interventions during treatment were found to be feasible with few adverse events reported. The included studies indicate positive effects of exercise during chemotherapy on muscle mass, muscle strength, functional performance, aerobic capacity, and HRQoL compared to usual care. Interpretation: Despite extensive search criteria, a limited number of heterogenous studies were eligible, which may explain the very low certainty of evidence for all outcomes. Nonetheless, exercise-based interventions conducted during treatment were feasible, safe and potentially effective. Further studies are needed to guide future exercise recommendations for these patients.

Older patients receiving antineoplastic treatment face challenges such as frailty and reduced physical capacity and function. This systematic review and meta-analysis aimed to evaluate the effects of exercise interventions on physical function outcomes, health-related quality of life (QoL), and symptom burden in older patients above 65 years with hematological malignancies undergoing antineoplastic treatment. This review adheres to Cochrane guidelines, with the literature searches last updated on 27 March 2024, including studies with patients above 18 years. Screening of identified studies, data extraction, risk of bias, and GRADE assessments were performed independently by two authors. Meta-analyses evaluated the impact of exercise, considering advancing age. Forty-nine studies contributed data to the meta-analyses. Five studies included patients with a mean age above 60 years, and none included only patients above 60. Exercise interventions had moderate to small positive effects on QoL global (SMD 0.34, 95% CI [0.04–0.64]) and physical function (SMD 0.29, 95% CI [0.12–0.45]). Age did not explain the variability in exercise effects, except for physical function (slope 0.0401, 95% CI [0.0118–0.0683]) and pain (slope 0.0472, 95% CI [0.01–0.09]), which favored younger patients. Exercise interventions improve physical function and QoL and reduce symptoms in adults with hematological malignancies undergoing antineoplastic treatment; however, the influence of age remains inconclusive.

Patient-reported health-related quality of life is a complementary healthcare outcome and important when assessing treatment efficacy. Using COSMIN methodological recommendations, this study evaluates the validity and reliability of a core heart disease-specific health-related quality of life questionnaire, the HeartQoL questionnaire (Danish version) in a sample of patients following heart valve surgery.
