Mucositis
Significant toxicity of anti cancer therapy
Mucositis – side effect of cancer treatment1-4
One of the unfortunate consequences of cancer treatment is the development of (oral) mucositis. It occurs after CT as well as radiotherapy:
Nearly 100 % of patients receiving head and neck radio therapy (RT), 80 % of patients receiving high-dose chemotherapy (CT) as conditioning for HSCT (Hematopoietic stem cell transplantation) and 20-40 % of patients receiving conventional CT are affected and up to 80% of patients receiving RT of the pelvic region (gastrointestinal symptoms).1
Effects of Gastrointestinal mucositis
- Malabsorption/diarrhea
- Higher intestinal permeability
- Increased risk of sepsis*
Effects of Oral mucositis
- Pain
- Erythema and ulcers
- Swallowing difficulties
- Decreased oral intake
- Increased risk of infections*
*particularly in immunocompromised patients (e.g. neutropenic patients)
Consequences for the patients
- Weight loss
- Impaired functional status
- Reduced quality of life
- Increased consumption of healthcare resources
- Reduction/cessation of treatment
- Less tumor control
- Longer/more frequent hospitalisations
- Impaired prognosis/higher mortality
As a consequence of mucositis patients may suffer from pain and difficulties eating which leads to weight loss because of (malnutrition and) reduced oral intake.
Thus, effective cancer treatment might be influenced. Management of mucositis is of utmost importance because it affects treatment, tolerability and overall quality of life.3
Early nutrition intervention to diminish treatment toxicities
• Less severe oral mucositis in patients meeting their protein-related goals8
• Fewer treatment interruptions for toxicity (e.g. mucositis) by early nutrition intervention9
Guideline recommendations:
ESMO Clinical Practice Guidelines2
Two key strategies for mitigation of oral mucosal injury before and during treatment:
1. Maintenance of optimal nutritional support
2. Daily oral hygiene
MASCC/ISOO 2015 recommend1:
All patients should be screened for
1. Nutritional risk
2. Swallowing difficulties, to initiate enteral feeding early
Supportive care for better treatment outcome
Nutritional support — important part of mucositis management strategy!
Oral glutamine – nutritional measure to support prevention and treatment of mucositis6
Gut tissue damage caused by radiation and/or chemotherapy might be enhanced by glutamine deprivation. Oral glutamine supplementation as measure of nutritional management may support anticancer treatment by contributing to reduce time of onset, severity and duration of mucositis.
A systematic review7 showed:
When oral glutamine supplementation is initiated before CT and/or RT at dose of 30g/d it significantly reduced mean grade2,3,4 mucositis, trend to reduced duration, time of onset and maximum grade of mucositis.
