Exercise and anemia in cancer patients: could make the difference?

Physical activity guidelines in oncology: A systematic review of the current recommendations

This review aims to summarize the recommendations endorsed by scientific societies regarding physical activity for patients with cancer. A systematic search was conducted to identify guidelines endorsed by scientific societies and published in the last 15 years dedicated to physical activity for cancer patients. The AGREE II instrument was used to assess the methodological quality of the guidelines. Results are presented as qualitative synthesis. A total of 11 guidelines met the inclusion criteria. Seven were considered high quality, scoring ≥60 % in the AGREE II tool. All the guidelines recommended to include aerobic and resistance training as types of activities. Regarding the physical activity dosage, most suggested a generic 150 minutes/week of moderate-intensity activity plus resistance training twice a week. Three guidelines reported instructions for exercise prescription, including frequency, intensity, and duration of training sessions. Six guidelines reported exercise testing/medical clearance instructions, 9 provided considerations regarding adaptation/precautions, and 7 detailed the specialists for referral. Four guidelines considered motivational aspects related to physical activity and cancer. Although important steps have been made in the more recent recommendations, effort is needed to produce high-quality research in the exercise-oncology field, with the ultimate aim of developing more tailored guidelines.

Integrating nutrition, physical exercise, psychosocial support and antiemetic drugs into CINV management: The road to success

Over the years, advancements in antiemetic drugs have improved chemotherapy-induced nausea and vomiting (CINV) control. However, despite the antiemetics therapies, in a relevant number of adult patients (∼30 %), CINV is still persistent, leading to several complications, such as electrolyte imbalances, anorexia, and treatment discontinuation. Supportive care interventions have gained credibility in cancer care, helping to improve patients' psycho-physical condition, quality of life, and managing symptoms, including CINV. Physical exercise and tailored nutritional counseling have demonstrated benefits in reducing the severity of nausea and vomiting. Psychological intervention has been postulated as a key approach in controlling anticipatory nausea/vomiting, as well as acupuncture/acupressure has been shown to decrease nausea and vomiting after chemotherapy treatments. In the current review, we aim to provide a clinical update on current prophylactic and delayed antiemetic guidelines for CINV and an overview of the non-pharmacological interventions tested for alleviating CINV in patients with cancer.

Advances in Diet and Physical Activity in Breast Cancer Prevention and Treatment

There is currently a growing interest in diets and physical activity patterns that may be beneficial in preventing and treating breast cancer (BC). Mounting evidence indicates that indeed, the so-called Mediterranean diet (MedDiet) and regular physical activity likely both help reduce the risk of developing BC. For those who have already received a BC diagnosis, these interventions may decrease the risk of tumor recurrence after treatment and improve quality of life. Studies also show the potential of other dietary interventions, including fasting or modified fasting, calorie restriction, ketogenic diets, and vegan or plant-based diets, to enhance the efficacy of BC therapies. In this review article, we discuss the biological rationale for utilizing these dietary interventions and physical activity in BC prevention and treatment. We highlight published and ongoing clinical studies that have applied these lifestyle interventions to BC patients. This review offers valuable insights into the potential application of these dietary interventions and physical activity as complimentary therapies in BC management.

Safety and efficacy evaluation of personalized exercise prescription during chemotherapy for lung cancer patients

BACKGROUND

To explore the safety and effectiveness of personalized exercise intervention during chemotherapy for lung cancer patients who were relatively weak and with compromised cardiopulmonary function.

METHODS

Thirty-eight lung cancer patients treated with chemotherapy at Peking University Third Hospital were enrolled in this prospective study. The exercise group (N = 21) received individualized exercise guidance based on personal test results and exercised regularly, while the control group (N = 17) only received exercise education and planed exercise methods according to their own preferences. Both groups underwent three fitness tests and clinical indicator assessments at 0, 6, and 12 weeks after starting the exercise, and the differences in trends of various indicators between the two groups were compared.

RESULTS

No exercise-related adverse events occurred during the 12-week exercise period. After 12 weeks of exercise training, in terms of fitness, the exercise group showed significant improvements in 6-min walk test (6MWT) (p < 0.001), peak oxygen consumption (VO2peak) (p = 0.005), muscle content (p < 0.001), muscle percentage (p < 0.001), and grip strength (p = 0.008) compared to the control group. In terms of clinical indicators, the exercise group showed significant improvements in vital capacity (p = 0.018), D-dimer (p = 0.031), and C-reactive protein (CRP) (p = 0.01), uric acid (p = 0.003), triglycerides (p < 0.001), functional average score (p < 0.001), and main symptom average score (p = 0.004) compared to the control group in trends over time.

CONCLUSION

Rehabilitation exercises using individualized exercise prescriptions tailored by exercise prescription specialists during chemotherapy are safe for lung cancer patients. Adhering to exercise can achieve comprehensive improvements in physical fitness and quality of life at 12 weeks.

Effect of exercise across the head and neck cancer continuum: a systematic review of randomized controlled trials

PURPOSE

This study aims to systematically explore the impact of physical exercise as supportive therapy for head and neck cancer.

METHODS

A systematic search on PubMed/MEDLINE, Cochrane, and SPORTDiscus was conducted. Randomized controlled trials exploring the effects of a physical exercise intervention in comparison with usual care on outcomes in patients with head and neck cancer were selected. The RoB 2 tool was used to determine the study quality. The extracted data are reported as qualitative synthesis.

RESULTS

Among the 527 records examined, nine studies were included. No trials investigating exercise as prehabilitation were found, whereas eight studies involving 452 patients with head and neck cancer were conducted during anticancer treatment. Most trials did not report improvements in body mass index or body composition, while 2/4 and 3/5 investigations found a significant increase in muscle strength and cardiorespiratory fitness, respectively. Regarding the patients' reported outcomes, 4 out of 7 studies observed enhancements in some domains of quality of life, and two trials out of 3 detected an amelioration in fatigue following the exercise intervention. Analyzing the exercise programs, it seems that combining aerobic and resistance training could be more beneficial compared to a single type of full-body exercise in counteracting physical decline and controlling symptoms in the anticancer therapy phase. One trial has investigated the effect of resistance exercise on patients who had terminated the anticancer treatments, reporting significant improvements in lean mass, muscle strength, and quality of life.

CONCLUSION

Exercise may be a promising approach in patients with head and neck cancer. Future studies are needed to consolidate these results.

Exploring the feasibility of a combined exercise program for patients with advanced lung or pancreatic cancer

Objective

This study aims to assess the safety, feasibility, and potential benefits of a combined aerobic and resistance exercise intervention for patients diagnosed with advanced pancreatic or lung cancer.

Methods

A prospective, single-arm study was conducted, enrolling patients with advanced lung or pancreatic cancer. Participants engaged in a 12-week exercise intervention comprising personalized bi-weekly aerobic and resistance training tailored to individual baseline conditions. The primary study outcomes focused on safety (absence of serious adverse events) and feasibility. Secondary outcomes included assessments of functional capacity using the "Six minutes walking test", strength measured through handgrip and leg press tests, anthropometric measures including body mass index and waist-hip ratio, quality of life (QoL), and changes in blood parameters.

Results

The study involved twelve patients (mean age 57.66 ​± ​7.40 years), with seven having pancreatic cancer and five having lung cancer. The recruitment rate was 50%, and assessment adherence was 100%, with an 84% adherence to the exercise program and no dropouts. No exercise-related adverse events were recorded, while three non-severe, non-exercise-related adverse events were observed: treatment-related dermatitis (Grade 2), axillary lymphadenopathy (Grade 2), and migraine (Grade 1). Significant enhancements in functional capacity, emotional well-being, and social functioning within the QoL domains were observed. Anthropometric measures, specifically waist-hip ratio and body mass index, remained stable.

Conclusions

The findings suggest that a tailored 12-week exercise intervention is both feasible and safe for patients with advanced lung or pancreatic cancer. This intervention appears to enhance functional capacity, specific aspects of QoL, and contribute to maintaining body weight.

Voluntary exercise does not always suppress lung cancer progression

Physical exercise can lower lung cancer incidence. However, its effect on lung cancer progression is less understood. Studies on exercising mice have shown decreased ectopic lung cancer growth through the secretion of interleukin-6 from muscles and the recruitment of natural killer (NK) cells to tumors. We asked if exercise suppresses lung cancer in an orthotopic model also. Single-housed C57Bl/6 male mice in cages with running wheels were tail vein-injected with LLC1.1 lung cancer cells, and lung tumor nodules were analyzed. Exercise did not affect lung cancer. Therefore, we also tested the effect of exercise on a subcutaneous LLC1 tumor and a tail vein-injected B16F10 melanoma model. Except for one case of excessive exercise, tumor progression was not influenced. Moderately exercising mice did not increase IL-6 or recruit NK cells to the tumor. Our data suggest that the exercise dose may dictate how efficiently the immune system is stimulated and controls tumor progression.

Combination of ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry and network pharmacology to reveal the mechanism of Shengyu Decoction for treating anemia

Anemia is a common clinical hematological disease with a high incidence, which seriously affects human health. Shengyu Decoction is often used in the treatment of anemia. However, the pharmacodynamic substance basis and therapeutic mechanism are still unclear, which hinders the comprehensive development and utilization of Shengyu Decoction. In this study, 143 compounds were identified in Shengyu Decoction using high-throughput ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry, 24 of which were absorbed into the blood. Taking these blood-entering ingredients as the research object, we found through network pharmacology research that ferulic acid, calycosin, and astragaloside A can act on AKT1, MAPK1, and MAPK14, and play a role in treating anemia through PI3K-Akt signaling pathway and Pathways in anemia. Finally, it was demonstrated that the active compound could bind to the core target with good affinity by molecular docking. The research shows that Shengyu Decoction has multi-component, multi-target, and multi-channel effects in the treatment of anemia, which provides a basis for the development and clinical application of Shengyu Decoction.
