Abstract

|
|
Background and Objectives : Radical surgery with radiotherapy is regarded as a
standard treatment modality of hypopharyngeal squamous cell carcinoma. However,
reports, on results of treatment and patterns of failure after surgery for hypopharyngeal
cancer are laking.
Patients and Methods : From July 1992 to December 1998, 39 previously untreated
hypopharyngeal carcinoma patients were treated with surgery with or without
postoperative radiotherapy at Severance Hospital. Ten were treated with surgery alone.
Results : The overall 5-year survival rate was 58.1%, of which 47.2% accounted for the
group who received surgery only and 64.6% for the group who received surgery plus
postoperative radiotherapy. Survival was best for posterior pharyngeal wall cancer(64.6%)
and worst for pyriform sinus cancer(56.1%). Recurrence was noted in 31%(12/39) of the
cases. The most common failure site was the neck. Among the neck failures, three
unusual retropharyngeal and paratracheal nodal failures were noted.
Conclusion : Treatment with radical surgery may improve survival of patients with this
notorious cancer. The extent of neck dissection for hypopharynageal carcinoma may
need to be evaluated with future trials.
