Everolimus, an mTOR inhibitor, may worsen radiation-induced esophagitis in renal cell carcinoma patients. This case highlights potential toxicity when combining everolimus with radiotherapy.
Area of Science:
- Oncology
- Pharmacology
Background:
- Everolimus (mTOR inhibitor) shows anticancer effects, including in renal cell carcinoma (RCC).
- Limited data exists on combining everolimus with radiotherapy.
Observation:
- A 63-year-old man with RCC received radiotherapy for vertebral metastases.
- Everolimus was administered sequentially after radiotherapy.
- The patient developed dysphagia, nausea, and vomiting.
Findings:
- Endoscopic examination revealed erosive esophagitis within the radiation field.
- The esophagitis correlated with the thoracic esophagus irradiation area.
Implications:
- Everolimus may exacerbate radiation-induced esophagitis.
- Clinicians should consider this potential toxicity when using sequential everolimus and radiotherapy.
