Purpose: The aim of this study was to assess the effectiveness, survival rate and complications of radiation therapy and chemoradiation treatment in hypopharyngeal cancer.

Methods and Materials: From January 1984 to December 1999, 56 patients who had hypopharyngeal carcinoma treated with curative radiation therapy were retrospectively studied. Twenty four patients (42.9%) were treated with radiation therapy
alone
(Group ¥°) and 32 (57.1%) treated with a combination of chemotherapy and radiation (Group ¥±). Total radiation dose ranged from 40.5 to 83. 5 §í (median 67.9 §í). Radiotherapy was given with conventional technique in 9 patients (16.4%), with
hyperfractionation ¥° (1.15¡­1.2 §í/fr., BID) in 26 (47.2%), hyperfractionation ¥± (1.35 §í/fr., BID) in 18 (32.7%), and accelerated fractionation (1.6 §í/fr., BID) in 2 (3.6%). In chemotherapy, 5-FU (1,000 §·/§³ daily for 5 consecutive days) and
cisplatin (100 §·/§³ on day 1) were administered in a cycle of 3 weeks interval, and a total of 1 to 3 cycles (average 2..3 cycles) were given prior to radiation therapy. Follow up duration was 1¡­195 months (median 28 months).

Results: Overall 2 and 5 year survival rates were 40.6% and 27.6%; 50.0% and 30.0% in Group ¥°, and 36.4% and 26.3% in Group ¥±, respectively. Complete local control rates in Group ¥° and ¥± were 70.0% and 67.7%, respectively. The response
to
radiotherapy and nodal stage were statistically significant prognostic factors. The complication rate was increased in Group ¥± and was decreased in hyperfractionation.

Conclusion: The response to radiotherapy and nodal stage were valid factors to indicate the degree of control over the hypopharyngeal cancer. The induction cisplatin, 5-Fu chemotherapy was not valid in terms of local control rate and
survival
rate, but did contribute to an increased complication rate. The use of hyperfractionation was valid to reduce the late radiation complications.
