Key approaches to interpret the findings of a meta-analysis on role of chemotherapy in 5000 patients with head and neck cancer treated by curative surgery (Letter)

Abstract

Dauzier and colleagues have recently published a paper in the journal Oral Oncology investigating chemotherapy in Head and Neck Cancer (HNC) patients treated using curative surgery [1]. This study was conducted as a subgroup analysis of a larger meta-analysis pertaining to HNC in over 5000 patients. Although the study conducted by Dauzier et al. has its merits, we believe that a few suggestions could serve to improve the quality of the study as well as address few issues.
