Effects of exercise prehabilitation and/or rehabilitation on health-related quality of life and fatigue in patients with non-small cell lung cancer undergoing surgery: A systematic review.

BACKGROUND: This systematic review aimed to appraise the current available evidence regarding the effects of exercise prehabilitation and rehabilitation on perceived health-related quality of life (HRQoL) and fatigue in patients undergoing surgery for non-small cell lung cancer (NSCLC). METHODS: Studies were selected according to Cochrane guidelines and assessed for methodological quality and therapeutic quality (the international CONsensus on Therapeutic Exercise aNd Training (i-CONTENT)). Eligible studies included patients with NSCLC performing exercise prehabilitation and/or rehabilitation and postoperative HRQoL and fatigue up to 90-days postoperatively. RESULTS: Thirteen studies were included. Exercise prehabilitation and rehabilitation significantly improved postoperative HRQoL in almost half of the studies (47%), although none of the studies demonstrated a decrease in fatigue. Methodological quality and therapeutic quality were poor in respectively 62% and 69% of the studies. CONCLUSION: There was an inconsistent effect of exercise prehabilitation and exercise rehabilitation on improving HRQoL in patients with NSCLC undergoing surgery, with no effect on fatigue. Due to the low methodological and therapeutic quality of included studies, it was not possible to identify the most effective training program content to improve HRQoL and reduce fatigue. It is recommended to investigate the impact of a high therapeutic qualified exercise prehabilitation and exercise rehabilitation on HRQoL and fatigue in larger studies.

The clinical decision-making process of healthcare professionals within a personalized home-based rehabilitation program during sequential chemoradiotherapy for stage III non-small lung cancer: A case study.

INTRODUCTION: The purpose of this case study was to demonstrate the clinical decision-making process of healthcare professionals within a rehabilitation program during chemoradiotherapy (CHRT) for a high-risk patient diagnosed with stage III non-small cell lung cancer (NSCLC). The course of CHRT and patient's preferences, facilitators, and barriers were considered. CASE-DESCRIPTION: The patient was a 69-year-old man with a history of rheumatoid arthritis diagnosed with stage III NSCLC. INTERVENTION: A home-based, personalized, and partly supervised rehabilitation program during CHRT, including aerobic, resistance, and breathing exercises, as well as nutritional counseling. OUTCOMES: The patient suffered from side effects of CHRT, which required adjustments in the context and intensity of the exercises. An important facilitator for the patient was encouraged by his wife in following the home-based rehabilitation program. During home visits, the patient and physiotherapists performed the exercises together to help him to overcome the burden and motivate the patient to adhere to the rehabilitation program. CONCLUSION: This case study demonstrates that physical exercise training could be performed by adjusting training intensity and the way in which the physical exercise training was delivered, while the patient experienced side effects from CHRT. In addition, the involvement and support of (in)formal caregivers seems essential for adherence to rehabilitation.

Association of Pretreatment Physical and Geriatric Parameters with Treatment Tolerance and Survival in Elderly Patients with Stage I-II Non-Small Cell Lung Cancer: An Evaluation of Usual Care Data.

In this study, the association of pretreatment physical and geriatric parameters with treatment tolerance and survival in elderly patients with stage I−II NSCLC was evaluated. Retrospective data for patients aged ≥70 years, diagnosed between 2016 and 2020 with stage I−II NSCLC, and who underwent surgery or stereotactic ablative radiotherapy (SABR) in a large Dutch teaching hospital were retrieved from medical records. Associations of pretreatment physical and geriatric parameters with treatment tolerance and survival were analyzed. Of 160 patients, 49 of 104 (47%) patients who underwent surgery and 21 of 56 (38%) patients who received SABR did not tolerate treatment. In univariable analysis, World Health Organization (WHO) performance status ≥ 2, short nutritional assessment questionnaire score > 1, short physical performance battery score ≤ 9, and geriatric-8 score ≤ 14 were significantly associated with postoperative complications. Forced expiratory volume of one second < 80% of predicted was significantly associated with intolerance of SABR. In multivariable analysis, WHO performance status ≥ 2 and diffusing capacity for carbon monoxide < 80% were significantly associated with decreased overall survival. This is the first study that investigated the association between pretreatment physical and geriatric parameters and treatment outcomes in patients with stage I−II NSCLC. Evaluation of physical and geriatric parameters before treatment initiation seems highly recommended to select patients who might benefit from preventive interventions before and/or during treatment.

Associations between outcome variables of nutritional screening methods and systemic treatment tolerance in patients with colorectal cancer: A systematic review.

INTRODUCTION: Multiple screening methods for malnutrition are available, but a systematic review of evidence in patients with colorectal cancer (CRC) is lacking. The aim of this study is to systematically investigate which outcome variables of nutritional screening methods are associated with treatment tolerance in patients with CRC. MATERIAL AND METHODS: A systematic review was performed with respect to outcome variables of nutritional screening methods and their association with systemic treatment tolerance in patients with CRC. The Cochrane guidelines for systematic reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Two authors independently assessed the risk of bias and quality of each included study. RESULTS: A total of sixteen studies were included. The following screening methods for malnutrition were assessed in the included studies: serum albumin, body mass index, C-reactive protein/albumin ratio, modified version of the Glasgow prognostic score, mini nutritional assessment, nutritional risk index, patient-generated subjective global assessment, sarcopenia and weight loss. DISCUSSION: Sarcopenia tended to be associated with treatment tolerance more often than other screening methods but the current review suggests that there are ample screening methods rendering meaningful outcomes regarding a patient's nutritional status and associated risk for treatment intolerance. This grants practitioners the flexibility to choose from a variety of different nutritional screening methods. Nutritional screening can thus be tailored to the individual patient. Importantly, nutritional screening may help identify those patients at risk for chemotoxicity thus allowing for the implementation of targeted prehabilitation programs in order to prevent (severe) chemotoxicity.

Feasibility of Rehabilitation during Chemoradiotherapy among Patients with Stage III Non-Small Cell Lung Cancer: A Proof-of-Concept Study.

Rehabilitation during chemoradiotherapy (CHRT) might (partly) prevent reduction in physical fitness and nutritional status and could improve treatment tolerance in patients with stage III non-small cell lung cancer (NSCLC). The aim of this proof-of-concept study was to investigate the feasibility of a multimodal program for rehabilitation during CHRT. A home-based multimodal rehabilitation program (partly supervised moderate-intensity physical exercise training and nutritional support) during CHRT was developed in collaboration with patients with stage III NSCLC and specialized healthcare professionals. A predetermined number of six patients with stage III NSCLC (aged > 50 years) who underwent CHRT and participated in this program were monitored in detail to assess its feasibility for further development and optimization of the program. The patient's level of physical functioning (e.g., cardiopulmonary exercise test, six-minute walking test, handgrip strength, body mass index, fat free mass index, energy and protein intake) was evaluated in order to provide personalized advice regarding physical exercise training and nutrition. The program appeared feasible and well-tolerated. All six included patients managed to perform the assessments. Exercise session adherence was high in five patients and low in one patient. The performed exercise intensity was lower than prescribed for all patients. Patients were motivated to complete the home-based rehabilitation program during CHRT. Preliminary effects on physical and nutritional parameters revealed relatively stable values throughout CHRT, with inter-individual variation. Supervised and personalized rehabilitation in patients with stage III NSCLC undergoing CHRT seems feasible when the intensity of the physical exercise training was adjusted to the possibilities and preferences of the patients. Future research should investigate the feasibility of a supervised and personalized rehabilitation program during CHRT with a low-to-moderate exercise intensity with the aim to prevent physical decline during CHRT.

Associations of Pretreatment Physical Status Parameters with Tolerance of Concurrent Chemoradiation and Survival in Patients with Non-small Cell Lung Cancer.

OBJECTIVE: The aim of this study was to evaluate associations between pretreatment physical status parameters and tolerance of concurrent chemoradiation (cCHRT) and survival among patients with stage III non-small cell lung cancer (NSCLC). METHODS: A retrospective cohort study was conducted among patients with stage III NSCLC who had received cCHRT between 2006 and 2015. Multivariate independent associations were analysed between the pretreatment parameters age, Charlson comorbidity index, World Health Organization performance status (WHO performance status), body mass index (BMI), fat-free mass index (FFMI), maximal handgrip strength, forced expiratory volume in one second and carbon monoxide lung diffusion capacity on the one hand with tolerance of cCHRT (defined as a received radiation dose at least equal to the prescribed radiation dose) and survival on the other hand. RESULTS: 527 of 577 patients (91.3%) tolerated cCHRT. A WHO performance status ≥ 2 (odds ratio (OR) 0.43) and BMI < 18.5 kg/m2 (OR 0.36) were associated with poorer tolerance of cCHRT. In the total group, a WHO performance status ≥ 2 (hazard ratio (HR) 1.73), low FFMI (HR 1.23) and intolerance of cCHRT (HR 1.55) were associated with poorer survival. CONCLUSION: In patients with stage III NSCLC receiving cCHRT, poor WHO performance status and BMI < 18.5 kg/m2 were independently associated with tolerance of cCHRT. Physical status parameters and intolerance of cCHRT were independently associated with poorer survival. Besides using this information for treatment decisions, optimizing physical status in patients at risk for intolerance of cCHRT might be a next step for improving treatment outcomes.
