Abstract

The impact of smoking on survival in patients with squamous cell carcinoma of the head and neck is well established, despite some conflicting data in the literature. However, data on alterations of smoking habit following cancer diagnosis is sparse. In the present study, the effect of reduction of smoking compared with cessation on the course of disease was studied. Data from 643 patients with HNSCC from the tumor documentation registry of the Department of Otorhinolaryngology, Head and Neck Surgery of the Christian‑Albrechts‑University Kiel were collected and statistically analyzed, looking at pre‑ and post‑treatment smoking habit and survival. Alteration of smoking at the first diagnosis of HNSCC led to a significantly beneficial effect on survival outcomes compared with continued smoking, without significant differences between reduction and cessation of smoking. Detailed analysis revealed that this effect was solely dependent on patients treated by surgery only. Lifelong non‑smokers exhibited a significant survival advantage compared with active and former smokers, with no difference in survival between these last two groups. The positive influence of altered smoking habit following first time diagnosis on disease‑specific survival paralleled the negative direct effect of active smoking on therapy, which is predominantly attributed to peritumoral tissue hypoxia leading to impaired efficacy of radiochemotherapy (RCT). In the present study cohort, the positive effect of smoking habit alterations were primarily observed in patients treated by surgery only instead of RCT, possibly due to fewer perioperative complications. These findings indicated that patients should be encouraged to at least minimize smoking following cancer diagnosis. Furthermore, for survival estimates and therapy planning, former smokers should be considered as active smokers.
