Singh F, et al. A systematic review of pre-surgical exercise intervention studies with cancer patients. Surg Oncol. 2013 Jun;22(2):92-104. Full-text for Emory users.
Results: Eighteen studies were included consisting of a total of 966 participants. Lung cancer studies were the predominant group represented. Most of the studies prescribed an aerobic intervention programs done prior to surgery. Mode, frequency, duration, and intensity of exercise intervention varied across the different cancer groups. The majority of studies showed preliminary positive change in clinical outcomes with significant improvements in the rate of incontinence, functional walking capacity and cardiorespiratory fitness.

- The concept of frailty has become increasingly recognized as one of the most important issues in health care and health outcomes and is of particular importance in patients with cancer who are undergoing surgery, chemotherapy,and radiotherapy. However, defining frailty can be challenging.
- Frailty is a complex, multidimensional, and cyclical state of diminished physiologic reserve that results in decreased resiliency and adaptive capacity and increased vulnerability to stressors.
- It has been demonstrated that frail patients are at increased risk of postoperative complications, chemotherapy intolerance, disease progression, and death. Although international standardization of frailty cutoff points is needed, continued efforts by oncology physicians and surgeons to identify frailty and promote multidisciplinary decision making will help to develop more individualized management strategies and optimize care for patients with cancer.

Results: Of 253 patients, 16.6% had preoperative cachexia, and 51.8% developed ≥ 1 postoperative complications. Complications were more common in cachectic patients (64.3% versus 49.3%, P = 0.07). This association varied by BMI category, and interaction analysis was significant for those with normal or underweight BMI (BMI < 25, P = 0.03). After multivariate modeling, in patients with normal or underweight BMI, preoperative cachexia was associated with higher odds of postoperative complications (odds ratios, 5.08 [95% confidence intervals, 1.18-21.88]; P = 0.029). Additional predictors of complications included major surgery (3.19 [1.24-8.21], P = 0.01), ostomy (4.43 [1.68-11.72], P = 0.003), and poor baseline performance status (2.31 [1.05-5.08], P = 0.03).
