Abstract
Between January 1997 and December 2013, the Charles University 3rd Medical School and Royal Vinohrady Teaching Hospital Ear, Nose and Throat oncology team treated 185 patients with advanced laryngeal cancer, which, from a surgical perspective, required a total laryngectomy. Overall, similar to 70% of these patients (n=129) underwent conventional treatment (i.e., total laryngectomy with post-operative radiotherapy), and similar to 30% (n=56) were treated with larynx preservation protocols (including primary radiotherapy, neoadjuvant chemotherapy followed by radiotherapy or chemoradiotherapy, or primary chemoradiotherapy).
Patients treated with laryngeal preservation protocols had a 5-year survival probability of 48%, whereas those treated with total laryngectomy and post-operative radiotherapy had a 5-year survival probability of 63%. This difference was not statistically significant.
However, patients who underwent primary surgical treatment survived for a significantly longer period (P70 years was identified to be statistically significant (P70 years (P<0.001) was selected in the second step; cervical nodal recurrence (P<0.001) in the third step; and disease stage (P<0.010) in the fourth step. Other parameters did not significantly affect survival.
The results of the present study confirmed that primary non-surgical treatment is an alternative approach to total laryngectomy, and that an informed patient should determine the treatment approach. The decreased overall survival observed in more extensive tumors suggests that surgical treatment may be a better selection in these cases.
Due to increased overall survival, primary non-surgical treatment may be recommended for younger patients. If the patient chooses primary non-surgical treatment, concomitant chemoradiotherapy is recommended.
If the patient cannot tolerate cytostatic chemotherapy, radiotherapy alone is recommended.
