Finizia C, Getenid Å, Holmberg E, Lindström J, Lundgren J. Advanced laryngeal cancer T3-T4 in Sweden: a retrospective study 1986-1990. Survival and locoregional control related to treatment. Different treatment modalities for advanced laryngeal cancer are much discussed in the literature. One-hundred-and-sixty patients with T3-4, N0-3, M0-l laryngeal cancer diagnosed in Sweden between 1986 and 1990 were retrospectively analysed. One hundred (65 T3; 35 T4) received radical radiotherapy with salvage surgery (RRSS) in case of residual or recurrent disease. Thirty-eight (11T3; 27 T4) patients received surgery with or without radiotherapy (S RT). Twenty-two patients received no treatment. After a median follow up of 4.4 years, the estimated 5-year actuarial corrected survival and 3-year locoregional control were 59% and 44% for T3 RRSS and 47% and 54% for T3 S RT. No significant difference between the different treatment modalities was found. the 5-year corrected survival rate and the locoregional control at 3 years between T4-RRSS (32%; 26%) and T4-S + RT (58%; 68%) groups were significantly different (p < 0.05 and P < 0.01). This might suggest that surgery with or without radiotherapy still has its place as a treatment modality for patients with advanced T4 laryngeal carcinoma.
