Management Approach for Cancer Physiology
The management of cancer physiology requires a multidisciplinary team-based approach integrating surgery, radiotherapy, systemic treatments, rehabilitation, and supportive care to optimize patient outcomes in terms of morbidity, mortality, and quality of life. 1
Multidisciplinary Team Structure
- Cancer care should be delivered in specialized cancer centers by a team consisting of medical oncologists, surgeons, radiation oncologists, radiologists, pathologists, and specialized nurses 1
- The team should have access to rehabilitation specialists, psychologists, physiotherapists, and geneticists when appropriate 1
- A specialized nurse or healthcare practitioner should serve as a patient navigator throughout the cancer journey 1
Physiological Assessment and Monitoring
- Initial assessment should include comprehensive evaluation of functional capacity through tests of body composition, aerobic capacity (6-minute walk), strength (30-second sit-to-stand), flexibility, and balance 2
- Clinical symptoms alone are not reliable in diagnosing underlying physiological changes; comprehensive investigation is required if symptoms don't respond to simple interventions 2
- Validated symptom questionnaires or patient-reported outcome measures should be routinely used to ensure accurate assessment 2
Exercise and Rehabilitation Interventions
- Exercise therapy should be integrated across the entire cancer continuum, from diagnosis through survivorship 2
- For patients with severe fatigue (7-10 on ESAS), light exercises are recommended while avoiding high-intensity activities 2
- For patients with fall risk, incorporate core and lower extremity strength, balance, and coordination exercises 2
- For patients with cytopenia, consider supervised, low-impact exercises with fall prevention strategies 2
- For patients with bone metastases, obtain medical clearance and focus on balance and isometric exercises 2
Managing Cancer-Related Symptoms
- Cancer treatments frequently cause multiple gastrointestinal symptoms that require identification of physiological deficits through appropriate testing 2
- Most patients developing symptoms after cancer treatment have more than one cause for their symptoms 2
- Common treatable physiological changes include bile acid diarrhea, carbohydrate intolerance, pancreatic exocrine insufficiency, and small intestinal bacterial overgrowth 2
- Investigating symptoms during active treatment is feasible and beneficial when symptoms impact treatment 2
Mind-Body Approaches
- Mind-body modalities that focus on interactions among brain, mind, body, and behavior can be effective adjunct therapies for managing symptoms like pain, dyspnea, and fatigue 2
- Massage therapy techniques including Swedish massage, aromatherapy massage, and reflexology can help reduce anxiety, depression, and pain in cancer patients 2
- Acupuncture and associated techniques have demonstrated efficacy in treating cancer-related nausea/vomiting and pain 2
Nutritional Management
- Nutritional counseling should be recommended as part of survivor care for all obese patients 2
- For patients with cancer cachexia, assessment of changes in patient-reported outcomes including symptoms and quality of life should guide interventions 2
- Early nutritional interventions should be considered in patients with metastatic cancer 2
Follow-up Care
- Regular clinical assessments should be conducted to provide optimal symptom management and maintain quality of life 1
- Ipsilateral and contralateral mammography is recommended every 1-2 years for breast cancer survivors 2
- Regular exercise provides functional and psychological benefits and may reduce recurrence risk 2
- Hormone replacement therapy increases recurrence risk and should be discouraged 2
Common Pitfalls and Challenges
- Administrative barriers often limit implementation of integrated models of care 2
- Guideline implementation is challenged by staffing limitations, workforce knowledge gaps, and clinical workflow issues 2
- Patients may not receive appropriate rehabilitation services if functional assessments aren't properly linked to referral pathways 1
- There is currently no comprehensive rehabilitation guideline or clinical pathway for cancer care, despite evidence supporting its importance 2
Patient Education and Involvement
- Information on diagnosis and treatment options should be provided repeatedly, both verbally and in writing 1
- Patients should be actively involved in all management decisions 1
- Patients need clear information about treatment purposes, potential side effects, and impacts on functional, emotional, and social well-being 1
- Post-cancer treatment can be isolating; patients often hesitate to ask for help with long-term side effects that impact quality of life 2
