Retrospective analysis of therapeutic effect and prognostic factors on early glottic carcinoma

The therapeutic effect was approximate in surgery group, radiotherapy group and photodynamic group, and all three treatment regimens achieved good clinical effect. Radiotherapy and photodynamic therapy may be the first or very important treatment on early stage glottic squamous cell cancer (Tis ∼ T2N0M0). However only 6 patients underwent PDT for T2 disease, making definitive treatment conclusions for this subgroup unclear.
