Background Infiltrating macrophage count (IMC) is found to correlate with the progression and prognosis of many human cancers. Methods This study used immunohistochemistry to measure the IMC (macrophages/high‐power field [HPF]) in 92 specimens of oral squamous cell carcinoma (OSCC). Results A significantly increased IMC was found in OSCCs with larger tumor size, positive lymph node metastasis, more advanced clinical stages, or recurrence (all p s < .05). Kaplan‐Meier survival analysis found that OSCC patients with IMC >196 macrophages/HPF had a significantly shorter disease‐free ( p = .001, log‐rank test) or overall survival ( p < .001, log‐rank test) than OSCC patients with IMC <196 macrophages/HPF. Multivariate Cox regression analyses showed that IMC >196 macrophages/HPF was an independent predictor for poor disease‐free ( p = .005) and overall survival of patients with OSCC ( p = .015). Conclusions The IMC can predict the progression and prognosis of OSCCs in Taiwan. © 2009 Wiley Periodicals, Inc. Head Neck, 2010
