Laryngectomy plus postoperative radio(system)therapy versus primary radio(system) therapy for the treatment of locally advanced laryngeal and hypopharyngeal cancer – results from the University Clinical Cancer Registry Regensburg

There are few adequate randomized clinical trials directly comparing the therapeutic options of primary laryngectomy (pLE) vs. primary radio(system)therapy (pR(S)T) in patients with locally advanced laryngeal and hypopharyngeal carcinoma and thus little clear scientific evidence to decide which patients will benefit most from which procedure.Aim was to compare survival between the therapeutic options and to learn from the limitations of this study, especially in the context of improved clinical assessment.The clinical data of patients treated between January 2010 and February 2022 were obtained from the electronic database of the University Hospital Regensburg. Overall survival (OS) and progression-free survival (PFS) were compared between the treatment groups.The study included 193 patients (pLE n = 68, pR(S)T, n = 125). Median OS was 31.2 months and median PFS was 24.7 months with no significant difference between the treatment groups (p > .050). Patients who did not receive complete treatment as recommended by the tumor conference (n = 47, 24.4%) had a higher risk of death (p = .024).The results of our study are consistent with the survival data reported in the literature. More detailed systematic data in clinical routine (e.g. relevant comorbidities) are required to ensure guideline-based recommended therapy.
