Brief summary
The study is designed to investigate the effect of a multicomponent prehabilitation pathway on early and long-term outcomes in elderly patients with frailty recovering from surgery for digestive cancer.
Detailed description
Frailty is an age-related syndrome characterized with diminished physiological reserve that results in decreased homeostatic capacity and increased vulnerability to any stress from minor to major. Approximately 10% to 20% of adults aged 65 years and older present with frailty, and the incidence doubles among those of 85 years and older. Among elderly cancer patients especially those with digestive cancer, the prevalence of frailty and pre-frailty can be as high as 50%. Malnutrition often coexists with frailty, and indeed contribute to the development of frailty. As a matter of fact, the proportion of malnutrition also increases with age even in high-income countries. Frailty is strongly associated with worsening outcomes in surgical patients, including higher delirium, high non-delirium complications, high perioperative mortality, as well as decreased activity of daily life, cognitive dysfunction and work disability in long-term survivors. Furthermore, malnutrition as a prominent factor in the development of frailty also has adverse impacts on the duration of hospitalization, complications, and survival after surgery. Therefore, it is urgently needed to understand how to enhance the recovery of these patients following surgery. Exercises and rehabilitation, in combination with nutritional supplement, may reverse or mitigate frailty, promote postoperative recovery, and improve clinical outcomes. However, the reported effectiveness varies with interventions and are not sufficiently robust to guide good clinical practice. The purpose of this study is to investigate the effect of multimodal prehabilitation on early and long-term outcomes in elderly patients with frailty.
Interventions
DIETARY_SUPPLEMENTPreoperative nutritional optimization
1. Indication for oral nutritional supplementation: Patients at risk of malnutrition (MNA-SF 8-11) or with malnutrition (MNA-SF 0-7). 2. Protocol of nutritional optimization: Enteral nutritional powder (Ensure for patients without diabetes and Glucerna for patients with diabetes) twice a day. The target protein intake is 1.5-1.8 g/kg/d. Patients with iron deficient anemia (hemoglobin \<130 g/L for men and \<120 g/L for women) will be given oral iron therapy. 3. The duration of nutritional optimization: The day admitted to the hospital to the surgery to one day prior to the surgery.
BEHAVIORALPreoperative exercise training
1. The respiratory training will be performed for at least 2-3 times per day. Respiratory training include thoracic breathing exercise and cough training. 2. Aerobic exercise will be performed for at least 1-2 times per day. Aerobic exercise includes jogging, walking or climbing stairs. Exercise intensity will be based on patients' tolerance. The goal of the training is to complete the training plan as far as possible. 3. Every training should be last for 45 minutes to 1 hour. If the patient can not tolerate, the training time should be reduce to 30 minutes. 4. The duration of exercise training: The day admitted to the hospital to the surgery to one day prior to the surgery.
BEHAVIORALPostoperative exercise training
1. Muscle strength training in the bedside and walking in the ward. 2. Aerobic exercise includes jogging, walking or climbing stairs. Exercise intensity will be based on patients' tolerance. The goal of the training is to complete the training plan as far as possible. 3. Exercise training is performed under the supervision of physiotherpists durign hospital stay, and is reminded by regular telephone calls and phone messages after hospital discharge.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| A composite of delirium and non-delirium complications within 7 days after surgery (sub-study). | Up to 7 days after surgery. | Delirium will be assessed with the 3-Dimensional Confusion Assessment Method. Non-delirium complications are defined as new onset medical events other than delirium that are harmful to patients' recovery and required therapeutic intervention, i.e., grade II or higher on Clavien-Dindo classification. |
| Recurrence-free survival after surgery. | Up to two years after surgery. | Events include recurrence, metastasis, or all-cause death, whichever come first. |
Secondary

| Quality of life at 30 days after surgery (sub-study). | At 30 days after surgery. | Quality of life will be assessed with the World Health Organization Quality of Life brief version (WHOQOL-BREF) which is a 24-item questionnaire that assesses the quality of life in physical, psychological, and social relationship, and environmental domains. The score ranges from 0 to 100 for each domain, with higher score indicating better function. |
