Brief summary
At the initial diagnosis of locally advanced nasopharyngeal carcinoma, a considerable proportion of patients have developed distant metastasis, forming subclinical lesions. Nowadays, with the advent of intensity modulated radiotherapy, the local-regional area is under well controlled. However, distant metastasis is still the main cause of failure in treatment of stage N2-3 nasopharyngeal carcinoma.The severe toxicity of synchronous chemotherapy and the dose intensity of single drug is not enough to effectively control existing subclinical lesions. Neoadjuvant chemotherapy with sufficient intensity (four cycles) can possible effectively kill subclinical lesions prior to the initiation of concurrent chemoradiotherapy, thereby reducing distant metastasis of stage N2-3 nasopharyngeal carcinoma. Meanwhile, four cycles of chemotherapy have been shown to be well tolerated in other tumors. In conclusion, 4-cycle neoadjuvant chemotherapy in combination with radiotherapy is expected to further control the distant metastasis rate of N2-3 nasopharyngeal carcinoma and improve the survival rate.
