Brief Summary:
This is a prospective, non-randomized phase III study observing the cognitive function changes with conformal hippocampus avoidance during intensity modulated radiotherapy for T4 nasopharyngeal carcinoma patients.

Condition or disease
Nasopharyngeal Carcinoma

Detailed Description:
All patients received intensity modulated radiotherapy or Tomotherapy with or without chemotherapy. Before radiotherapy, the patients will receive brain MRI scanning and the brain MRI images will be fused with the head and neck CT scan images. The investigators develop the treatment plan with hippocampus avoidance. Cognitive function are evaluated before,during and after radiotherapy. Dose-volume Histograms are got to analyze the associated factors.

Hippocampus avoidance: decrease the dose to hippocampus as low as possible without affecting the target volumes and other normal tissues

Primary Outcome Measures :
  1. the dose-volume relationship between hippocampus and cognitive function [ Time Frame: 1 year ]
    To explore the relationship between cognitive impairment and exposure dose of hippocampus in patients with nasopharyngeal carcinoma.

Secondary Outcome Measures :
  1. cognitive function changes [ Time Frame: 1 year ]
    response to the Montreal Cognitive Assessment

  2. memory function changes [ Time Frame: 1 year ]
    response to the Hopkins Verbal Learning Test

  3. quality of life [ Time Frame: 1 year ]
    response to the QLQ-C30
