Relapse patterns in WHO 2/3 nasopharyngeal cancer: Is there a difference between ethnic Asian vs. non-Asian patients?

Conclusions: Although this study provides no evidence that race is an independent prognostic factor for overall survival in patients with WHO 2/3 NPC, it does suggest that relapse patterns may vary, with a higher rate of late primary failures (offset by a lower rate of distant failure) in the Asian population. Further confirmatory studies with larger patient cohorts are indicated.
