Management of Radiation Mastitis

Local heat application is the appropriate management for radiation mastitis. 1

Understanding Radiation Mastitis

Radiation mastitis is an inflammatory condition of the breast that occurs as a side effect of radiation therapy used in breast cancer treatment. It represents a form of radiation dermatitis specifically affecting breast tissue following radiotherapy.

Management Approach

First-Line Treatment: Local Heat Application

• Local heat application is the primary recommended treatment for radiation mastitis, as it helps improve blood circulation, reduces inflammation, and provides symptomatic relief 1
• The irradiated area should be kept clean between treatments, which is the most important step in managing radiation dermatitis 1
• After cleaning, the application of a non-perfumed moisturizer is optional but may provide additional comfort 1

Additional Supportive Measures

• For mild cases (Grade 1 radiation dermatitis), management can primarily be handled by nursing staff 1
• For moderate to severe cases (Grades 2-3), an integrated management team approach is recommended, involving radiation oncologists, nurses, medical oncologists, and dermatologists as required 1
• Skin reactions should be assessed at least once weekly during treatment 1

Topical Applications That May Be Considered

• Drying gels with antiseptics (e.g., chlorhexidine-based creams, but not chlorhexidine in alcohol) 1
• Hydrophilic dressings applied after radiotherapy to the cleaned area 1
• Anti-inflammatory emulsions (e.g., trolamine, hyaluronic acid cream) 1
• Zinc oxide paste if it can be easily removed before radiotherapy 1

Treatments to Avoid

• Danazol therapy is not indicated for radiation mastitis and is therefore incorrect 1
• Therapeutic breast massage could potentially worsen inflammation and is not recommended 1
• Simple mastectomy would be an extreme and inappropriate response to radiation mastitis, which is a manageable condition with conservative measures 1
• Overtreatment, including overuse of antiseptic creams, should be avoided as it can irritate the skin 1

Management of Complications

• If infection is suspected, the treating physician should use clinical judgment, including considering swabbing the area to identify infectious agents 1
• Topical antibiotics should be reserved for superinfection and should not be used prophylactically 1
• Blood granulocyte counts should be checked if infection is suspected, especially in patients receiving concomitant chemotherapy 1
• Blood cultures should be performed if additional signs of sepsis and/or fever are present 1

Prevention Strategies

• Standardized radiation techniques should be used to minimize skin reactions, including appropriate dose fractionation (4,500 to 5,000 cGy at 180 to 200 cGy per fraction) 1
• Bolus should not be used during radiation treatment as it can increase skin reactions 1
• Proper patient positioning and treatment planning are essential to minimize unnecessary radiation exposure to normal tissues 1

By following these evidence-based guidelines, radiation mastitis can be effectively managed while minimizing complications and maintaining quality of life for patients who have undergone radiation therapy for breast cancer.
