Abstract

Objectives To investigate the utilisation of different treatment modalities for patients with laryngeal cancer (LC) during last decade in Poland.

Setting Retrospective population-based study.

Participants Patients with LC treated between January 2009 and December 2018.

Primary and secondary outcome measures The contemporary utilisation of treatment modalities of LC: surgery with intent of radical resection (total or partial laryngectomy), radiotherapy (RT) and chemoradiotherapy (CRT).

Results There was determined the overall number of 22 957 new diagnosis of LC from 2010 to 2018 and confirmed the steady decrease in the incidence rate of LC in the following years from 7.7 to 6.03. The mean age of patients with LC was raising by an average of 0.3832 of year per year. There was observed decrease in number of total laryngectomies (TLs) in subsequent years (from 1122 in 2009 to 776 in 2018). The number of procedures involving partial laryngeal resection was within stable ranges however the upward trend was observed separately for vocal cordectomy. There was established decreased involvement of surgery in LC treatment from 52.8% in 2009 to 24.3% in 2016 with the subsequent rise to 33.7% in 2018. The percentage of patients receiving RT increased from 23.8% in 2009 to 42.1% in 2013 with the next decrease to 25.7% in 2018. The utilisation of CRT in LC treatment was progressively increasing over analysed years from 23.4% in 2009 reaching 40.6% in 2018.

Conclusions The presented data revealed an increase in total number of organs preserving treatment modality with CRT in subsequent years with decreasing number of TLs in Polish patients with LC.
