Radiobiological and quality of life study of conventional and accelerated fractionated radiotherapy in patients with head and neck squamous cell carcinoma: Correlation of efficacy with cell cycle analysis parameters.

Conclusions This study identified that both radiotherapy arms were equivalent in terms of QoL and toxicity.  The number of cells in S phase correlated negatively but not-significantly with overall survival. A statistical significant improvement of quality of life was observed one month after the end of irradiation in both arms. More patients with eligible for analysis specimens are needed for the extraction of safe results.
