Why is nasopharyngeal carcinoma treated with radiotherapy rather than surgery?

Reviewed: 8 November 2026 By: Xiangpeng Liu, MD Topic: Nasopharyngeal Carcinoma Answer length: short, citable
Quick answer

The nasopharynx lies deep behind the nose, close to the skull base, major blood vessels and cranial nerves, so wide surgical removal is rarely feasible at diagnosis. Non-keratinising NPC is also exceptionally radiosensitive and chemosensitive, making IMRT with or without chemotherapy the curative standard. Surgery is reserved for residual or locally recurrent disease.

In detail

IMRT shapes the radiation dose around the tumour while limiting dose to the salivary glands, brainstem, spinal cord, temporal lobes, mandible and eyes. A typical curative course is about 33 weekday fractions over six to seven weeks.
