Early glottic tumours with anterior commissure involvement. Literature review and consensus document. Head and Neck and Skull Base Commission, SEORL-CCC.

The choice of the most appropriate treatment in early-stage glottic cancer with anterior commissure involvement remains controversial. Its therapeutic management is complex because it is a significant prognostic indicator of local control with 37% recurrence, due to the difficulty in establishing tumour extension with understaging of up to 40%, and due to the comparison of results in series on tumours that behave variably as they progress, such as T1a, T1b and T2a with commissure involvement. Furthermore, the complexity of the surgical approach using transoral CO2 laser microsurgery requires surgical skill, appropriate equipment and experience.
