  1. aChemotherapy was applied for advanced disease (stage > 2), at 30 mg/m2 per week.
  2. bDosimetry was averaged over both hippocampi.
  3. cTwo-sample t-test with significant value (p-value < 0.05) was used to test the difference between groups. “*” denotes p-value < 0.05.
  4. dAbout 15 cigarettes a day on average prior to the diagnosis of NPC.
  5. eAbout 300 c.c. of beer per day.
  6. fAbout 20 betel nuts per day prior to the diagnosis of NPC.
  7. The values denoted in count number for item of subjects, sex, education, smoke, alcohol, betel, depression, diabetes, hypertension and cancer stage; the others are presented in mean ± standard error of the mean (SEM).
