Chemoradiotherapy for recurrent CBTs case report

Area of Science:

• Oncology
• Neurosurgery

Background:

• Carotid body tumors (CBTs) are rare paragangliomas, typically treated with surgery.
• Postoperative recurrence of CBTs presents a significant clinical challenge.

Purpose of the Study:

• To present a case of recurrent carotid body tumor managed with a multimodal approach.
• To evaluate the efficacy of chemoradiotherapy as a salvage treatment for anatomically complex recurrent CBTs.

Main Methods:

• A 49-year-old female with recurrent CBT involving the jugular foramen was treated.
• Treatment included image-guided radiation therapy (IGRT) and 4 cycles of CVD chemotherapy.
• Response was assessed using RECIST criteria.

Main Results:

• The patient achieved stable disease post-treatment.
• This outcome supports the use of chemoradiotherapy in select recurrent CBT cases.

Conclusions:

• Multimodal therapy, including chemoradiotherapy, can be effective for recurrent CBTs.
• Further research and standardized protocols are needed to validate this approach for complex recurrences.
