What is the single conclusion that can be drawn from the findings of the Veterans Affairs Laryngeal Study Group in 1991, which compared two treatments for advanced laryngeal cancer – laryngectomy followed by radiotherapy versus chemotherapy followed by radiotherapy? The study randomly assigned 332 patients with advanced laryngeal cancer to one of the groups, and those in the chemotherapy group who did not respond to treatment underwent salvage laryngectomy. The results showed that both groups had a 2-year survival rate of 68%, but a higher percentage of chemotherapy patients (64%) were able to retain their larynx. Additionally, more local recurrences occurred in the chemotherapy group, while fewer distant metastases occurred in the same group.
