Brief Summary

Currently, most protocols of nasopharyngeal carcinoma (NPC) of various research bodies such as the Radiation Therapy Oncology Group require routine elective irradiation to the retropharyngeal area and to levels II-V lymph nodal areas regardless of the status of nodal metastasis. Previous studies had confirmed that the pattern of cervical lymph node (LN) metastasis in NPC followed an orderly manner. Retropharyngeal LNs were the most commonly involved, followed by upper neck levels II, III, or VA nodes, and finally to the lower neck nodes including level IV and VB nodes; and the incidence of LN skip metastasis is rare, ranging from 0.5% to 7.9%. It was rare for NPC patients without neck LN metastases to experience neck failure after elective irradiation to levels II, III and VA. It was also confirmed that with unilateral LN metastases of higher-level LNs usually spread down ipsilateral LNs. Thus, the investigators conduct the non-inferior randomized trial to determine the value of elective neck irradiation in NPC patients with unilateral or bilateral uninvolved neck.

Outcome Measures

Primary Outcomes (1)

  • Regional relapse-free survival

    The regional relapse-free survival rate will be estimated using Kaplan-Meier method for each arm from the date of randomization to the date of nodal relapse or death from any cause, whichever occurred first. Their differences will be compared between treatment arms using the log-rank test.

    3 year

Secondary Outcomes (37)

  • Radiation-related toxicity

    Within 1 month after radiotherapy for acute toxicity; long term for late toxicity

  • Overall survival

    3 year

  • Local relapse-free survival

    3 year

  • Distant metastasis-free survival

    3 year

  • Patient's quality-of-life: global health status

Study Arms (2)

Elective neck irradiation

EXPERIMENTAL

Whole neck irradiation is given in the involved neck. Elective neck irradiation of Level II,III and Va lymph node area is given in the uninvolved neck, and Level IV and Vb lymph node area were not irradiated in the uninvolved neck.

Radiation: Elective neck irradiation

Whole neck irradiation

ACTIVE COMPARATOR

Whole neck irradiation is given regardless of the involved or uninvolved neck.

Radiation: Whole neck irradiation

Interventions

Whole neck irradiation is given in the involved neck. Elective neck irradiation of Level II,III and Va lymph node area is given in the uninvolved neck, and Level IV and Vb lymph node area were not irradiated in the uninvolved neck.
