Although previous studies have shown that preoperative pulmonary rehabilitation training may improve postoperative prognosis in patients with lung cancer, the literature included in the existing meta-analysis is highly heterogeneous and lacks effective subgroup analysis. Therefore, an updated meta-analysis is needed to integrate the latest published randomized controlled clinical trials (RCT). This updated analysis was performed to identify the clinical effects of preoperative pulmonary rehabilitation on physical rehabilitation (lung function, activity endurance, and dyspnea), psychological rehabilitation, quality of life, length of hospital stay, and postoperative pulmonary complications in patients with lung cancer. The PubMed, Embase, Cochrane Library, and Web of Science database were searched since inception up to March 2024. A random-effects model was used to pool data, and sensitivity and subgroup analyses were performed to explore the stability of outcomes and potential sources of heterogeneity. All analyses were conducted via Review Manager 5.4.1 and STATA 15.0. The final analysis included 11 RCTs with 1250 patients. The results of meta-analysis suggest that preoperative pulmonary rehabilitation can significantly improve the quality of life of patients with lung cancer after surgery (SMD: 0.16; 95% CI: 0.01, 0.32; P = 0.04) and significantly reduce the risk of postoperative pulmonary complications (PPCs) (RR: 0.39; 95% CI: 0.25, 0.60; P < 0.0001). The results of subgroup analysis suggested that the effect of combined preoperative and postoperative rehabilitation was significantly better than that of preoperative rehabilitation alone, and the effect of short-term preoperative pulmonary rehabilitation (≤ 3 weeks) was significantly better than that of long-term rehabilitation. Preoperative pulmonary rehabilitation for patients with lung cancer can significantly improve their postoperative quality of life and reduce postoperative complications, but factors such as intervention time and intervention method may affect the rehabilitation effect.

There is no universally accepted definition for surgical prehabilitation. The objectives of this scoping review were to (1) identify how surgical prehabilitation is defined across randomised controlled trials and (2) propose a common definition. The final search was conducted in February 2023 using MEDLINE, Embase, PsycINFO, Web of Science, CINAHL, and Cochrane. We included randomised controlled trials (RCTs) of unimodal or multimodal prehabilitation interventions (nutrition, exercise, and psychological support) lasting at least 7 days in adults undergoing elective surgery. Qualitative data were analysed using summative content analysis. We identified 76 prehabilitation trials of patients undergoing abdominal (n=26, 34%), orthopaedic (n=20, 26%), thoracic (n=14, 18%), cardiac (n=7, 9%), spinal (n=4, 5%), and other (n=5, 7%) surgeries. Surgical prehabilitation was explicitly defined in more than half of these RCTs (n=42, 55%). Our findings consolidated the following definition: 'Prehabilitation is a process from diagnosis to surgery, consisting of one or more preoperative interventions of exercise, nutrition, psychological strategies and respiratory training, that aims to enhance functional capacity and physiological reserve to allow patients to withstand surgical stressors, improve postoperative outcomes, and facilitate recovery.' A common definition is the first step towards standardisation, which is needed to guide future high-quality research and advance the field of prehabilitation. The proposed definition should be further evaluated by international stakeholders to ensure that it is comprehensive and globally accepted. [ABSTRACT FROM AUTHOR]
