Summary
Custom-made mold brachytherapy offers a viable treatment option for recurrent basal cell carcinoma (BCCA) after previous treatments. This approach demonstrated minimal side effects and good disease control in a patient requiring reirradiation.
Area of Science:
- Oncology
- Radiation Oncology
- Dermatology
Background:
- Recurrent basal cell carcinoma (BCCA) poses a treatment challenge, especially after initial surgery and radiotherapy.
- Reirradiation strategies are crucial for managing locally advanced or recurrent tumors.
- Custom-made mold brachytherapy presents a potential solution for targeted reirradiation.
Observation:
- A patient with recurrent basal cell carcinoma of the auditory canal, previously treated with surgery and external beam radiotherapy, was considered for reirradiation.
- Surgical excision of the recurrent tumor was performed, followed by mold brachytherapy.
- A total dose of 25 Gy was delivered to a 5mm depth within the surgical bed using custom-made mold brachytherapy.
Findings:
- The patient tolerated the mold brachytherapy treatment well, with no acute toxicities observed.
- Follow-up after 2 years revealed no apparent late morbidities.
- The patient achieved good disease control without significant adverse effects.
Implications:
- Custom-made mold brachytherapy is a feasible alternative for reirradiation in selected BCCA patients.
- This technique offers a minimally morbid approach for managing recurrent tumors.
- Effective disease control can be achieved with targeted brachytherapy in challenging cases.
