Effects of a Strength Physical Exercise Program in Chronic Lymphocytic Leukemia Patients

Официальное название

Effects of a Strength Physical Exercise Program in Chronic Lymphocytic Leukemia Patients on Quality of Life, Mental Health, and Frailty.

Обзор

Chronic lymphocytic leukemia (CLL) is a hematological neoplasm that primarily affects older individuals and is the most common type of leukemia in adults in Western countries. CLL mainly affects older adults, with an average age at diagnosis of around 70 years, and there is a slightly higher risk in men compared to women. It is characterized by the proliferation of clonal B lymphocytes in peripheral blood, bone marrow, and lymphoid organs. Although CLL has a relatively slow progression in many cases, patients may experience chronic fatigue, muscle weakness, functional impairment, and psychological disorders, such as anxiety and depression, which significantly affect their quality of life. In this context, it has been shown that physical exercise, especially strength training, can considerably improve physical and psychological conditions in oncology populations, such as those with breast cancer and colorectal cancer, as well as in older adults, where the benefits of resistance training are widely recognized. These benefits include increased muscle strength, reduced fatigue, improved functional abilities, psychological well-being, and overall quality of life. Furthermore, there is evidence that exercise can reduce systemic inflammatory markers, such as C-reactive protein (CRP), and improve lipid profiles by lowering total cholesterol and triglycerides, which is crucial for cancer patients at risk of cardiovascular diseases.

Подробное описание

Current research on the effects of physical exercise in patients with CLL is limited. While some studies suggest that cancer patients may benefit from physical exercise, most research has focused on other types of cancer, such as breast, lung, or colorectal cancer. In the case of patients with CLL, in addition to functional and psychological issues, they often experience chronic inflammation and alterations in lipid profiles, which can increase the risk of cardiovascular comorbidities.

Inflammatory markers, such as C-reactive protein (CRP) and pro-inflammatory cytokines (IL-6, TNF-α), are common in patients with CLL, and it has been suggested that modulating these markers through exercise may help control systemic inflammation. Strength training, in particular, could be beneficial for improving the inflammatory and lipid profiles in these patients, although this has not been thoroughly evaluated in this population.

Regarding mental health, studies have reported that patients with CLL experience high levels of anxiety and depression, which significantly deteriorate their quality of life. In other oncology populations, exercise has proven effective in reducing these symptoms and improving overall well-being. However, it has not been sufficiently studied whether these effects can be replicated in patients with CLL, representing a gap in the current literature.

Finally, the loss of muscle strength, a key indicator in the diagnosis of sarcopenia according to the diagnostic algorithm proposed by the European Working Group on Sarcopenia in Older People in 2019 (EWGSOP2), should be considered another common issue in patients with CLL, due to both the average age of the patients (70 years) and the disease itself or the side effects of treatment. Although it has been shown that physical exercise in general, and strength exercise in particular, can improve muscle strength and functional capacity in older adults and cancer patients, studies evaluating these effects in patients with CLL are lacking. Assessing how a strength training program can influence functional recovery and improve the quality of life of these patients is crucial for their clinical management.

Вмешательства

• Другое Exercise
  Supervised strength exercise sessions: There will be two sessions per week, each lasting 50 minutes. Each session will consist of three distinct parts: Warm-up: 10 minutes of global strength and aerobic exercises at 6/10 on the Rating Perceived Exertion (RPE) scale. Strength training: 6 strength exercises targeting the major muscle groups, lasting 30 minutes. The initial load will be set at 70% of the estimated 1-RM (assessed in the first session and based on the individual patient). When the
• Другое Home exercise
  Participants will complete three weekly home training sessions that will not coincide with supervised training days. Each session will last 20 minutes, they will complete two sets of five exercises, with one minute of work and one minute of rest.
