Summary
Stereotactic radiotherapy (SRT) shows promise for early-stage external auditory canal carcinoma (EACC). This treatment led to tumor regression or disappearance in most patients, with stable conditions even after re-treatment for recurrence.
Area of Science:
- Oncology
- Radiation Oncology
- Otolaryngology
Background:
- External auditory canal carcinoma (EACC) can present superficially, leading to early diagnosis.
- Early-stage EACCs typically have less frequent lymph node involvement or distant metastases.
- Stereotactic radiotherapy (SRT) is a potential treatment due to its ability to deliver high-dose radiation to the primary tumor.
