Patients and Methods A total of three hundred and ninety five hypopharyngeal cancer patients received radical treatment at our hospital 96 were male. The majority were habitual smokers 88 alcohol drinkers 73 and or betel quid chewers 51 . All patients received a CT scan or MRI for tumor staging before treatment. The stage distribution was stage I 2 0.5 stage II 22 5.6 stage III 57 14.4 and stage IV 314 79.5 . Radical surgery was used first in 81 patients 20.5 and the remaining patients 79.5 received organ preservation-intended treatment OPIT . In the OPIT group 46 patients received radiotherapy alone 156 patients received chemotherapy followed by radiotherapy CT RT and 112 patients received concomitant chemo-radiotherapy CCRT . Results The five-year overall survival rates for stages I II III and IV were 49.5 47.4 and 18.6 respectively. There was no significant difference in overall and disease-specific survival rates between patients who received radical surgery first and those who received OPIT. In the OPIT group CCRT tended to preserve the larynx better p 0.088 with three-year larynx preservation rates of 44.8 for CCRT and 27.2 for CT RT. Thirty-seven patients developed a second malignancy with an annual incidence of 4.6 . Conclusions There was no survival difference between OPIT and radical surgery in hypopharyngeal cancer patients at our hospital. CCRT may offer better laryngeal preservation than RT alone or CT .
