Clinical Prehabilitation Protocol for Breast Cancer (Ca Breast) Patients

Definition and Rationale

• Surgery (mastectomy, lumpectomy, axillary dissection, reconstructive procedures) and neoadjuvant chemotherapy both impose significant physiologic stress
• Preoperative functional reserve predicts postoperative complications, hospital length of stay, and long-term recovery
• The window of neoadjuvant therapy (chemotherapy/radiotherapy before surgery) provides an ideal structured time frame for prehabilitation - no surgical delay is needed
• Prehabilitation has been shown to improve physical function, quality of life, and psychosocial outcomes in breast cancer patients (Toohey et al., Breast Cancer Res Treat 2023 - systematic review of 14 studies, 7 RCTs) [PMID: 36269525]

Phase 1: Initial Assessment (Weeks -6 to -4 Before Treatment)

1.1 Functional Assessment

1.2 Nutritional Assessment

1.3 Psychological Assessment

Perioperative anxiety is estimated to affect >50% of cancer patients and is associated with increased anesthetic requirements, higher rates of postoperative nausea/vomiting, delirium, and non-home discharges (Sabiston Textbook of Surgery, p. 365).

1.4 Medical Optimization

• Cardiac evaluation (ECG, echo if indicated) per ACC/AHA guidelines
• Pulmonary function if symptomatic or smoker
• Glycemic control: target HbA1c <8% before elective surgery
• Medications review: anticoagulants, steroids, immunosuppressants, NSAIDs
• Anemia work-up and treatment: target Hb ≥10 g/dL; iron supplementation, EPO if indicated

Phase 2: Multimodal Prehabilitation Program (Weeks -6 to -1)

2.1 Exercise Component

• Frequency: 3-5 sessions/week
• Modality: Walking, cycling, swimming (low-impact preferred post-diagnosis)
• Intensity: Moderate (50-70% HRmax; RPE 11-14 on Borg scale)
• Duration: 20-45 minutes/session; progressive
• Minimum pre-treatment target: 150 min/week moderate-intensity (per WCRF/AICR guidelines)

• Frequency: 2-3 sessions/week (non-consecutive days)
• Muscle groups: Full body, with specific emphasis on upper limb and shoulder girdle
• Intensity: 2-3 sets of 8-15 reps at 50-70% 1-rep max
• Purpose: Counteract sarcopenia (prevalence 10-24% in breast cancer - Jang et al., 2024); preserve lean mass through chemotherapy

• Active and passive range of motion (ROM) exercises for shoulder
• Pendulum exercises; wall climbing; overhead reaches
• Rationale: Reduces post-surgical upper limb disability and axillary web syndrome (AWS)
• The PROSPER trial demonstrated reduced upper limb disability after breast cancer surgery with structured exercise programs (Sabiston Textbook of Surgery, p. 365, REHABILITATION section)

• Incentive spirometry: 10 reps every 2 hours while awake
• Diaphragmatic breathing exercises
• If mastectomy + reconstruction planned: pectoralis and chest wall mobility exercises

• Slow deep breathing (5 sec inhale / 5 sec exhale), yoga-based breathing
• Especially relevant if patient is undergoing anthracycline or taxane chemotherapy (cardiotoxicity risk)

2.2 Nutritional Component

• Correct existing malnutrition or pre-sarcopenia
• Build nutritional reserves before catabolic phase of surgery/chemotherapy
• Target protein intake: 1.2-2.0 g/kg/day (cancer patients, per ESPEN guidelines)
• Caloric target: 25-35 kcal/kg/day

• Registered dietitian-led individualized dietary counseling
• High-protein dietary optimization (lean meats, legumes, dairy, eggs)
• Oral nutritional supplements (ONS) if dietary intake inadequate
• Omega-3 fatty acid supplementation (1-2 g/day EPA+DHA): anti-inflammatory, may reduce cancer-related cachexia
• Micronutrient correction: Vitamin D (target >30 ng/mL), iron, B12, folate as indicated
• Pre-treatment carbohydrate loading (if no diabetes): 400 mL carbohydrate drink the evening before and morning of surgery
• Manage obesity if BMI >30: modest caloric restriction combined with exercise (not aggressive caloric restriction)

2.3 Psychological / Psychosocial Component

• Cognitive Behavioral Therapy (CBT): First-line for anxiety and depression (structured 4-8 session program)
• Sleep Restriction Therapy (SRT): For patients with insomnia prior to chemotherapy/surgery (INVEST trial protocol - nurse-delivered, 4-week program); early management improves QOL and potentially survival
• Mindfulness-Based Stress Reduction (MBSR): 8-week program; reduces cortisol, improves anxiety/depression
• Guided imagery and music therapy: Evidence-based adjuncts; reduce perioperative anxiety
• Acupuncture: Shown effective for anxiety mitigation in preoperative period
• Peer support groups / breast cancer navigator: Social support structures

Multiple modalities can be individualized to hospital resources and patient preference, allowing customization while maintaining evidence-based practice (Sabiston Textbook of Surgery, p. 365).

2.4 Smoking and Substance Cessation

• Smoking cessation at least 4-6 weeks before surgery (6-8 weeks for optimal pulmonary benefit)
• Nicotine replacement therapy (NRT), varenicline, or bupropion per guidelines
• Alcohol: screen with AUDIT-C; brief intervention (FRAMES model) for hazardous use; >2 drinks/day associated with increased postoperative infections, pulmonary complications, longer ICU stay
• Opioid use: Screen and optimize; high preoperative opioid use predicts readmission
• Integrate with ACS Strong for Surgery framework if available

Phase 3: ERAS Integration and Perioperative Bridge (Week -1 to Day of Surgery)

ERAS + Prehabilitation (PreHab) work synergistically: one study found the combination shortened hospital stay, reduced intraoperative blood loss, improved costs by 22% over ERAS alone (Sabiston Textbook of Surgery, p. 365).

• Registered Dietitian - nutritional assessment and intervention
• Psycho-oncologist / Clinical Psychologist - CBT, MBSR, insomnia management
• Oncology Nurse / Nurse Navigator - coordination, patient education
• Anesthesiologist - perioperative optimization, ERAS integration
• Social Worker - support systems, transportation barriers

Special Considerations for Breast Cancer

1. Neoadjuvant chemotherapy window: For patients receiving neoadjuvant therapy (anthracyclines, taxanes, HER2-targeted agents), the 12-24 weeks of chemotherapy before surgery creates an ideal prehabilitation window - exercise during this period counteracts chemotherapy-induced fatigue, sarcopenia, and cardiotoxicity.
2. Axillary procedures: Patients undergoing sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) need dedicated shoulder and axillary ROM prehabilitation to prevent axillary web syndrome and shoulder dysfunction.
3. Reconstruction: Immediate breast reconstruction (IBR) extends surgery duration and recovery - more intensive prehabilitation with chest wall, pectoralis, and core strengthening is indicated.
4. Lymphedema prevention: Arm precautions education preoperatively; baseline arm circumference measurement; prehabilitation upper limb exercise does NOT increase lymphedema risk (evidence confirms safety).
5. Cardiotoxicity risk: Patients receiving anthracyclines (doxorubicin) or trastuzumab - baseline ECHO / MUGA scan, cardiac fitness monitoring throughout prehabilitation; aerobic exercise may have cardioprotective effects.
6. Body image / psychosocial: Mastectomy and body-altering surgery have significant psychological impact; early psychological prehabilitation and peer support are particularly important in this population.

Implementation Models

• McGill POP (Perioperative Program): Integrates prehabilitation into perioperative clinic; 4-week multimodal program; most evidence-based model for oncologic prehabilitation
• ACS Strong for Surgery: Checklist-based preoperative screening including rehabilitation; frailty screen for patients >65
• MSHOP (Michigan Surgical & Health Optimization Program): Home-based walking program + education on nutrition, smoking, stress; demonstrated reduced LOS and Medicare payments across 21 hospitals; scalable model
• Home-based telemedicine prehabilitation: Particularly relevant post-COVID; emerging evidence for digital delivery of exercise programs with remote monitoring
