Table 2 Distribution of patients with different IHC score by treatment

From: Weak expression of cyclooxygenase-2 is associated with poorer outcome in endemic nasopharyngeal carcinoma: analysis of data from randomized trial between radiation alone versus concurrent chemo-radiation (SQNP-01)

IHC score CRT RT
Negligible (0) 8 9
Weak (1–4) 10 7
Moderate (5–8) 4 4
Strong (9–12) 9 7
  1. Abbreviations: IHC, immunohistochemistry; RT, radiation; CRT, chemoradiation.
  2. Fisher's exact test showed no significant difference of IHC expression levels between patients who received RT versus CRT levels (p = 0.933).
