Exercise and pathologic complete response to cancer treatment: a systematic review and meta-analysis.

PURPOSE: Neoadjuvant chemotherapy (NACT) is a commonly recommended approach for treating several cancers, and improving patients' outcomes to this therapy is important. This systematic review and meta-analysis assessed the impact of exercise on pathologic complete response (pCR), a key short-term marker of treatment efficacy, in patients with solid tumors receiving NACT. METHODS: Four electronic databases were searched for randomized controlled trials with physical exercise during NACT as an intervention published until May 2025. Risk of bias was assessed using Cochrane RoB 2.0 and the TESTEX scale. A random-effect meta-analysis using the inverse variance method synthesized the results. Heterogeneity was assessed using I2 and chi2 statistics. Risk ratio estimated the effect size. RESULTS: Eight studies involving 504 patients with breast, esophageal, gastric, or rectal cancer were included in the final analysis. Exercise interventions consisted of aerobic and resistance exercise. Overall, there were no significant differences between exercise and control groups in the rate of pCR to NACT (pooled risk ratio: 1.08 (95% CI: 0.82 to 1.43) Z = 0.56, p = 0.58). However, meta-regression data from breast cancer (BC) studies (4 studies, 367 participants) suggest exercise may be associated with enhanced tumor response to NACT in HR + /HER2- subtypes (regression coefficient: 0.83 (95% CI: -0.00 to 1.67), p = 0.05). CONCLUSION: Exercise during NACT did not improve pCR across cancer types. Exploratory meta-regression findings suggest a possible benefit of exercise in BC patients with the HR + /HER2- subtype. These results should be interpreted with caution due to the small number of studies and low certainty of the evidence.

Exercise assessment of cardiac function in children and young adults before and after bone marrow transplantation.

Cardiac toxicity is a potential complication of bone marrow transplantation because recipients frequently receive cardiotoxic chemotherapy and/or irradiation before transplantation. Most studies indicate that transient cardiac toxicity occurs within weeks of transplantation, but few studies have evaluated either cardiac status before or late after transplantation. Cardiac performance was assessed via cycle ergometry in 20 children and young adults before transplantation and 31 other children and young adults after transplantation. Mean survival time in the group post-transplantation was 3.9 years with a range of 11 months to 12.1 years. Left ventricular size and shortening fraction at rest were assessed via echocardiography. Data were compared to those of 70 healthy subjects from our laboratory. Patients before and after transplantation had normal oxygen consumptions and cardiac indices at rest. During exercise, however, patients treated for cancer both before and after bone marrow transplantation had reduced exercise times, reduced maximal oxygen consumptions, and reduced ventilatory anaerobic thresholds. Cardiac reserve, as judged by the response of the cardiac output during exercise, was reduced severely. There were no significant differences between the groups tested before and after transplantation. Patients who had been treated for aplastic anemia, who had received less intensive therapy before transplantation, performed significantly better than did patients treated for cancer. Despite these findings, only four patients had abnormalities by echocardiography. In conclusion, before transplantation patients with oncologic diagnoses had serious limitations in exercise performance, most likely as a result of the effects of the cardiotoxic therapy given as part of their conventional cancer therapy. Long-term survivors of bone marrow transplantation also had similar abnormalities.(ABSTRACT TRUNCATED AT 250 WORDS)

Tumor Signatures of Physical Fitness: Insights from a Preclinical Model.

PURPOSE: Cardiorespiratory fitness (CRF) and muscle strength are associated with cancer risk/mortality in adults. However, there is yet no evidence for pediatric tumors. This study investigated the association of CRF and muscle strength with several tumor-related phenotypes in an aggressive childhood malignancy, high-risk neuroblastoma. METHODS: Twelve mice-bearing orthotopic high-risk neuroblastomas were studied. CRF and muscle strength were assessed using treadmill and grip strength testing, respectively. The following tumor-related outcomes were studied: survival, clinical severity, tumor weight/volume, metastasis, and intratumor immune infiltrates. In addition, tumor samples underwent quantitative proteomic analysis via liquid chromatography-tandem mass spectrometry. Spearman correlations (or logistic regression) were performed between CRF/muscle strength and the abovementioned variables. Proteins that were significantly correlated with CRF or muscle strength were mapped into protein-protein interaction (PPI) networks using the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) database. RESULTS: CRF was inversely correlated with clinical severity score ( r = -0.657, P = 0.020). Of 6840 identified tumor proteins, 76 correlated significantly with CRF (19 positively, 57 negatively), whereas 194 correlated with muscle strength (97 positively, 97 negatively). Proteins correlated with CRF were primarily involved in metabolic and structural pathways, including angiotensinogen and elastin. In turn, muscle strength-associated proteins were more abundant and included keratin family proteins (e.g., keratin, type I cytoskeletal 14, and type II cytoskeletal 5), proteins involved in cell adhesion (e.g., desmoglein-1-alpha), and translational regulators (e.g., eukaryotic initiation factor 4A). Network analysis revealed significant enrichment in structural organization and cellular adhesion pathways. CONCLUSIONS: Besides the association of CRF with clinical severity of the tumor, distinct novel tumor proteomic signatures associated with CRF and muscle strength were identified, highlighting potential mechanisms linking physical fitness with childhood cancer biology.

Exercise for the mitigation of cancer therapy-related cardiac dysfunction in breast cancer patients treated with anthracyclines: a systematic review and meta-analysis.

PURPOSE: Cancer therapy-related cardiac dysfunction (CTRCD) is a significant concern for breast cancer patients undergoing anthracycline-based chemotherapy. Although exercise has been proposed as a cardioprotective strategy, existing reviews have largely examined heterogeneous cancer populations receiving varied treatments, leaving a gap in the evidence base focused exclusively on anthracycline-induced CTRCD. This systematic review and meta-analysis aimed to address that gap by evaluating the effects of long-term exercise on key CTRCD markers in breast cancer patients treated exclusively with anthracyclines. METHODS: A comprehensive search of PubMed, Scopus, Cochrane Central Register of Controlled Trials, and Web of Science was conducted for randomized controlled trials including breast cancer patients undergoing anthracycline-based chemotherapy, receiving long-term exercise interventions (≥ 12 weeks, ≥ 1 session/week) compared to usual cancer care, and reporting at least one of the following outcomes: left ventricular ejection fraction, global longitudinal strain, cardiac troponin I, cardiac troponin T, or N-terminal prohormone of brain natriuretic peptide. RESULTS: Six randomized controlled trials involving 360 participants were included. Exercise significantly attenuated cardiac troponin I elevation compared to controls (SMD = -0.50; 95% CI, -0.93 to -0.06; p = 0.02). No statistically significant between-group differences were observed for left ventricular ejection fraction, global longitudinal strain, cardiac troponin T, or N-terminal prohormone of brain natriuretic peptide. CONCLUSION: The cardioprotective role of exercise during anthracycline treatment remains uncertain, though the attenuation of cardiac troponin I elevation suggests a potential protective signal warranting further investigation through larger, standardized trials employing advanced assessment modalities and longer follow-up periods.

The future of precision oncology and artificial intelligence in Belgium: scenarios and policy responses.

PURPOSE: Precision medicine, also known as personalized medicine, enables the provision of tailored health services to patients. In the prevention, early detection, and treatment of cancers, precision medicine is highly promising, given the increasing use of genomic profiling for diagnosis and adapting therapies in several tumor types. Artificial Intelligence (AI) can support this process by analyzing vast amounts of relevant data. However, high-quality data and financial investments in the health system are essential for the implementation of precision medicine and AI solutions in routine cancer care. DESIGN/METHODOLOGY/APPROACH: Building on the quantitative outcomes of a foresight exercise published in another study, this article collects qualitative data to gain more detailed insights into the future of precision oncology in Belgium and discusses the role of AI in this field. It reports the results of a series of expert workshops, focusing on four hypothetical future scenarios that are centered around technological and economic issues that must be overcome for the widespread use of precision oncology in Belgium. FINDINGS: The study concludes that all four scenarios discussed in the workshops would require supportive policy measures in Belgium, which should go beyond mere technological and economic considerations, such as involving patient associations and the public in policy design or creating multi-disciplinary expert groups for precision medicine. ORIGINALITY/VALUE: To the best of our knowledge, this is the first study to employ foresight methodology to illustrate possible future scenarios, scrutinize feasible approaches for implementing precision oncology in Belgium, and discuss the use of AI in this context.

Constipation related to narcotic therapy. A protocol for nurses and patients.

Constipation is a well-known side effect of narcotics and can add to the total burden of pain of cancer patients in need of pain medication. There is little literature on this topic, and it has been suggested that one reason is that the definitions are vague and socially bound. It has also been suggested that some physicians consider constipation a trivial problem, resulting in a relative lack of attention to the subject. Although this article addresses narcotic-induced constipation, other types related to poor dietary and exercise habits and to disease are mentioned and may be contributing factors. There are a number of drugs and treatments available to treat the problem, but the emphasis of nursing care should be on prevention of constipation. Senna derivatives have been noted to reverse the major constipating effect of narcotics, i.e., the decrease in propulsive movements of the colon, and it is recommended they be given right along with narcotics as a preventive measure. A protocol that incorporates a schedule of drugs and dosages and specific patient and nursing guidelines for daily evaluation of bowel function, with education about dietary, fluid, and exercise requirements, will help nurses practice prevention and contribute to patients' comfort.

[Diagnostic difficulties and errors in early stomach cancer].

Difficulties that occur in the diagnosis of early gastric carcinoma (EGC) were studied on a material of 1617 prophylactic endoscopic examinations of persons who did not make any complaints of the alimentary organs and 2158 primary gastroscopies performed in accordance with the patients' complaints, results of the dispensary follow-up of 811 patients who made up a risk group, and an analysis of case reports of 183 patients in whom EGC was confirmed by surgery. The authors emphasize a high percentage of errors determined by the lack of the pathognomonic symptomatology, difficulties of interpreting the endoscopic appearance and histologic confirmation of carcinoma. To improve early diagnosis of gastric carcinoma (GC), it is recommended that every endoscopic investigation be performed with oncological apprehension, paying attention even to the minimum focal changes in the gastric mucosa and making spot biopsy of those changes. It is also advisable that a more strict approach should be exercised to the formation of risk groups, restricting them to the patients at greater risk for GC or with unrecognized GC (first revealed and poorly healing ulcers, polyps measuring over 2 cm in diameter, grade III dysplasia discovered in gastric biopsy specimens). Such patients should be placed under dispensary observation including endoscopy which is to be made in the first stage after 1, 3 and 6 months.

[Histology, fine structure and differentiation of experimental Wilms tumors (author's transl)].

Histologic studies indicate that the cycasin-induced Wilms' tumor in the rat is equal to human nephroblastoma in appearance. Therefore, it may represent an interesting system for experimental oncology. In electron microscopy, the spindle cells of the sarcoma region mostly represent tubular cells. Besides, the author's results showed that preexisting mesenchyma cells and blood vessels also form part of the tumor. Electron microscopy studies have shown that cycasin feeding will lead to early cellular changes indicating that cycasin exercises a nucleotoxic effect. Present results do not favor the dysontogenic concept of the formation of Wilms' tumor, since this tumor can be induced diaplacentally.

[Rehabilitation in oncology].

Successful rehabilitation can only be carried out by the precise teamwork of doctors, nurses and therapeutic personnel whereby, especially in cancer patients, importance of psycho-somatic aspects are emphasized. Under all circumstances, rehabilitation must immediately follow acute therapy. Especially, the rehabilitation of cancer patients convince them, that they are not lost. It is desirable that rehabilitation of cancer patients should increase, preferably in specialized oncology rehabilitation centers - similar to the cardiological or rheumatic rehabilitation centers. The main purpose of general rehabilitation in oncology should be the somatic and psychological revitalization of the patient under the motto: Don't merely prolong life, add worthwhile living for each life.

Exercise prehabilitation in head and neck cancer patients proposed for definitive chemoradiotherapy: The FIT4TREAT randomized controlled trial.

BACKGROUND: Patients with head and neck cancer (HNC) initially scheduled for definitive chemoradiotherapy (CRT) often experience early functional decline and deterioration in health-related quality of life (HRQoL) even before treatment initiation. Evidence for prehabilitation in this non-surgical setting remains limited. This study evaluated whether exercise prehabilitation (EP) initiated before CRT improves functional capacity compared with usual care (UC). METHODS: FIT4TREAT (ClinicalTrials.gov: NCT05418842) was a prospective, single-center, randomized clinical trial. Adults with HNC proposed for definitive CRT were randomly assigned (1:1) to EP or UC. EP consisted of supervised combined aerobic and resistance exercise performed three times per week from baseline until radiotherapy initiation. The primary outcome was the six-minute walk distance (6MWD) at the end of the pre-treatment period. Secondary outcomes included muscle strength, lower-limb functionality, body composition, and HRQoL assessed using the EORTC QLQ-C30 and QLQ-HN43. RESULTS: Between May 2021 and February 2025, 47 patients were enrolled; 40 were included in the primary analysis. After adjustment for baseline 6MWD and the randomization stratification variables, EP resulted in a significantly greater pre-treatment 6MWD than UC (adjusted between-group difference, 28.6&#xa0;m; 95&#xa0;% CI, 4.1-53.1; P&#xa0;=&#xa0;0.023). EP also improved lower-limb functionality (P&#xa0;<&#xa0;0.001) and was associated with better preservation in the QLQ-C30 summary score (P&#xa0;=&#xa0;0.008), social functioning (P&#xa0;=&#xa0;0.038) and body image (P&#xa0;=&#xa0;0.011). CONCLUSION: EP before definitive CRT improves functional capacity and may help preserve HRQoL in patients with HNC, supporting its potential integration into routine oncology care.

Hypnosis and related techniques in pain management.

Hypnosis has been used successfully in treating cancer patients at all stages of disease and for degrees of pain. The experience of pain is influenced not only by physiological factors stemming from disease progression and oncological treatment, but also from psychosocial factors including social support and mood. Each of these influences must be considered in the successful treatment of pain. The successful use of hypnosis also depends upon the hypnotizability of patients, their particular cognitive style, their specific motivation, and level of cognitive functioning. While most patients can benefit from the use of hypnosis, less hypnotizable patients or patients with low cognitive functioning need to receive special consideration. The exercises described in this chapter can be successfully used in groups, individual sessions, and for hospice patients confined to bed. Both self-hypnosis and therapist guided hypnosis exercises are offered.

[(General rehabilitation in oncology)].

Rehabilitation has become a modern expression. For many years optimal rehabilitation has been carried out in many different sectors of illness. Too few activities, however, have been developed for the rehabilitation and control of cancer patients. No other group requires rehabilitation as foremost as that of cancer patients who need a complete and complex program which besides pure medical treatment affords psychosomatic care primarily. By developing a program under the title "Wiener Modell" (Vienna Model), our department was able to put into practice a suitable program for the control of cancer patients. The success was possible due to the excellent teamwork of doctors, nurses and therapeuts as well as the inter-disciplinary cooperation of all specialists available in a municipal modern hospital.
