HOW TO PREPARE FOR MAJOR CANCER SURGERY:
PREHABILITATION AND NUTRITION
The 4โ8 weeks before major cancer surgery are not dead time โ they are your window to actively reduce complication risk, speed recovery, and give yourself the best chance of tolerating adjuvant therapy afterwards.

Why Prehabilitation Matters: The Evidence
The concept is simple โ the fitter, better-nourished, and psychologically stronger a patient is before surgery, the better they withstand the physiological stress of the operation and the faster they recover.
โThe window between diagnosis and surgery is not wasted time โ it is your opportunity to become a better surgical candidate. Every week of prehabilitation invested before surgery pays dividends in recovery speed and complication reduction.โ
Complications Reduced by 30โ50%
Systematic reviews of prehabilitation programmes for major abdominal, colorectal, oesophageal, and thoracic surgery consistently show 30โ50% reductions in post-operative complications โ pneumonia, wound infections, DVT, anastomotic leak โ compared to non-prehabilitated controls.
Faster Return to Baseline Function
Prehabilitated patients return to their pre-operative physical function 4โ6 weeks faster than standard-care patients โ directly influencing their ability to start adjuvant chemotherapy or immunotherapy on time, which significantly impacts long-term oncological outcomes.
The Four Pillars of Effective Prehabilitation
A complete prehabilitation programme addresses four evidence-based domains โ each independently reduces surgical risk; together they multiply the benefit.
1. Exercise Training
Aerobic exercise (walking, cycling, swimming) 30 minutes, 3โ5 times/week increases cardiorespiratory fitness (VOโ max) โ the single strongest predictor of operative risk and recovery speed. Resistance training (2โ3 sessions/week) preserves muscle mass lost during neoadjuvant chemotherapy. Minimum 4 weeks training; 8 weeks preferred. Even patients with poor baseline fitness benefit significantly.
2. Nutritional Optimisation
Protein intake 1.2โ1.5 g/kg body weight/day is the key target โ supporting muscle mass preservation, immune function, and wound healing. Malnutrition at surgery triples complication rates. Oral nutritional supplements (ONS) bridge the gap for patients unable to meet protein targets through food alone. A pre-operative dietitian assessment identifies deficiencies early.
3. Smoking Cessation
Smoking cessation โฅ4 weeks before surgery halves pulmonary complication rates (pneumonia, atelectasis, prolonged ventilation). For thoracic and upper GI surgery โ where pulmonary complications are the primary driver of morbidity and mortality โ this is one of the most impactful single interventions available. Even 2โ4 weeks cessation produces measurable benefit.
4. Psychological Preparation
Anxiety and poor psychological preparedness increase pain perception, analgesia requirements, and hospital stay after surgery. Preoperative education, breathing techniques, and formal psychological support (where indicated) measurably improve post-operative outcomes. Patients who understand what to expect โ and why โ cooperate better with physiotherapy, nutrition, and early mobilisation.
Prehabilitation Priorities by Operation Type
The relative importance of different prehabilitation components varies by surgical site and the dominant complication risk for each operation.
| Operation | Top Priority | Minimum Lead Time | Specific Targets |
|---|---|---|---|
| Oesophagectomy | Exercise + smoking cessation (pulmonary risk dominant) | 6โ8 weeks | VOโ max >15 mL/kg/min; FEV1 >70% predicted; BMI normalisation; protein โฅ1.2 g/kg |
| Whipple / Pancreatic surgery | Nutritional + exercise (malnutrition common) | 4โ6 weeks | Albumin >30 g/L; weight stabilisation; protein supplementation; 4ร weekly aerobic exercise |
| Major hepatic resection | Exercise + alcohol reduction (liver function critical) | 4โ6 weeks | Alcohol cessation โฅ4 weeks; aerobic fitness; nutrition optimisation |
| Cystectomy | Exercise + nutritional (older patient population) | 4โ6 weeks | Protein โฅ1.2 g/kg; aerobic + resistance exercise; psychological preparation for stoma/neobladder |
| VATS lobectomy | Exercise + smoking cessation (pulmonary) | 4โ6 weeks | Smoking cessation โฅ4 weeks; aerobic exercise targeting VOโ max >15 mL/kg/min; incentive spirometry |
| Radical gastrectomy | Nutritional (dysphagia/weight loss common) | 4โ6 weeks | Caloric deficit correction; protein supplementation; nasogastric feeding if severe dysphagia |
| Major rectal surgery (TME) | Exercise + pelvic floor (continence) | 4โ8 weeks (after neoadjuvant CRT) | Pelvic floor exercises pre-operatively; aerobic fitness; nutritional support during/after CRT |
A Practical 6-Week Prehabilitation Plan
Most patients have 4โ8 weeks between diagnosis/neoadjuvant therapy and surgery โ enough time to make a meaningful difference with a structured programme.
- 1
Week 1: Assessment and Baseline
Dietitian review (malnutrition screening, protein needs, supplement prescription). Physiotherapy fitness assessment (6-minute walk test or CPET if indicated). Smoking cessation consultation. Anaesthetic pre-assessment โ baseline cardiovascular and pulmonary function documented.
- 2
Weeks 1โ6: Exercise Programme
Aerobic exercise: 30 min walk or cycle at moderate intensity, 5 days/week. Resistance exercise: bodyweight or light resistance 2โ3 sessions/week (squats, lunges, upper body). Incentive spirometry (10 breaths ร 10 reps, 4ร daily) โ particularly for thoracic and upper GI surgery.
- 3
Weeks 1โ6: Nutritional Protocol
Protein target: 1.2โ1.5 g/kg/day (e.g. 84โ105 g/day for 70 kg patient). Caloric target: 30โ35 kcal/kg/day. ONS (oral nutritional supplement) prescribed if diet alone insufficient โ 2 bottles/day (500โ600 kcal, 20 g protein each). Multivitamin + vitamin D supplementation if deficient.
- 4
Weeks 1โ4+: Smoking and Alcohol
Complete smoking cessation from day 1 โ NRT, varenicline, or bupropion with GP/nurse support. Alcohol: reduce to <2 units/day; complete cessation recommended for hepatic resection and upper GI surgery. Sleep optimisation โ 7+ hours/night supports immune function and tissue repair.
- 5
Weeks 2โ6: Psychological Preparation
Surgical education sessions (what to expect at each stage โ reduces fear of unknown). Breathing and relaxation techniques practised daily โ diaphragmatic breathing, progressive muscle relaxation. Identify and address specific anxiety drivers โ stoma adjustment, pain, body image changes. Family involvement in preparation improves patient resilience.
With Prehabilitation vs Without: The Difference
Published evidence comparing prehabilitated and standard-care patients consistently demonstrates meaningful differences across multiple outcomes.
With Prehabilitation
- 30โ50% fewer post-operative complicationsParticularly pneumonia, wound infection, anastomotic complications, and DVT
- 2โ4 day shorter hospital stayLess time in hospital reduces infection exposure and allows earlier recovery at home
- Earlier return to pre-operative function (4โ6 weeks faster)Directly affects eligibility for on-time adjuvant chemotherapy start
- Better tolerance of adjuvant therapyPatients with better pre-surgical nutritional and functional status tolerate full-dose adjuvant therapy more reliably
Without Prehabilitation
- Higher complication ratesFrailty, malnutrition, and deconditioning independently predict post-operative complications
- Longer hospital stay and ICU admissionsPulmonary complications from deconditioning or smoking extend ICU stay significantly
- Slower return to baseline functionRecovery takes weeks to months longer without pre-operative fitness and nutrition optimisation
- Adjuvant therapy delays and dose reductionsUnder-recovered patients often cannot start or complete adjuvant chemotherapy on schedule โ directly affecting oncological outcomes

Frequently Asked Questions
Prehabilitation Before Cancer Surgery
Can I do prehabilitation if I am having neoadjuvant chemotherapy before surgery?
Yes โ and this is particularly important. The period during neoadjuvant chemotherapy is exactly when patients lose muscle mass, fitness, and nutritional status most rapidly. Continuing structured exercise (even at reduced intensity during chemotherapy) and maintaining protein intake (1.2โ1.5 g/kg/day) significantly blunts the deconditioning caused by chemotherapy. Patients who maintain fitness through neoadjuvant therapy arrive at surgery in substantially better condition than those who rest throughout โ directly improving their surgical risk profile and recovery speed.
How much exercise is required before surgery?
The evidence-based minimum is 30 minutes of moderate-intensity aerobic exercise (brisk walking, cycling, swimming) 3โ5 times per week, beginning at least 4 weeks before surgery. Moderate intensity means being able to hold a conversation but working hard enough to be mildly breathless. Resistance training (2โ3 sessions/week) is added for patients with significant muscle mass loss. Starting from very low fitness is fine โ even patients with baseline ECOG PS 2 who improve their fitness through prehabilitation show meaningful reductions in post-operative complications. Any exercise is better than none.
