Abstract:
We hypothesized that patients with head and neck squamous cell carcinoma (HNSCC) with smoking cessation during curative chemoradiotherapy (CRT) had fewer complications and lower tumor progression risks. Methods Sixty‐three patients with nonmetastatic HNSCC who were smokers at diagnosis (carbon monoxide [CO] breath concentrations ≥3 ppm) and underwent curative CRT were prospectively enrolled. Successful smoking cessation throughout CRT was confirmed by CO breath concentrations 〈 3 ppm at CRT completion. Results Forty‐one patients (65%) successfully discontinued smoking throughout CRT. With a median 33‐month follow‐up, patients with successful smoking cessation during CRT had significantly fewer, greater, and lower probabilities of grade ≥3 acute toxicities ( P = .01), progression‐free survival ( P = .03), and permanent gastrostomy or tracheostomy ( P = .04), respectively, than those continuing smoking throughout CRT. In multivariate analysis, successful smoking cessation during CRT significantly reduced tumor progression risks (hazard ratio: 0.4, P = .05). Conclusion Smoking cessation during curative CRT reduced treatment‐related toxicities and tumor progression risks in patients with HNSCC.
