Will nasopharyngeal carcinoma recur after radiotherapy? How to treat nasopharyngeal carcinoma

Will nasopharyngeal carcinoma recur after radiotherapy?

Nasopharyngeal carcinoma is a malignant tumor that can be cured early. Recurrence after radiotherapy is common within 2-3 years, and significantly reduced after more than 3 years. Recurrence requires treatment after pathological diagnosis to eliminate radiation damage factors. After recurrence of nasopharyngeal carcinoma, radiotherapy can be repeated or combined with surgery.

How is nasopharyngeal cancer treated?

Since pathological examinations are mostly poorly differentiated squamous cell carcinoma, radiotherapy is recognized as the first choice of treatment. Conventional radiotherapy has many complications, so three-dimensional conformal or enhanced radiotherapy is recommended. The total irradiation dose to the nasopharynx is 66~70Gy/6.5~7 weeks, the radical dose for positive cervical lymph nodes is 56~60Gy, and the preventive radiation dose for negative cervical lymph nodes is 46~50Gy.

During radiotherapy, chemotherapy, traditional Chinese medicine, and immunotherapy can be used in combination to improve the efficacy. Comprehensive treatment methods such as chemotherapy and surgery can be used for some advanced patients and recurrence cases after radiotherapy, as well as a small number of adenocarcinomas and squamous cell carcinomas that are not sensitive to radiation.
