Zusammenfassung: | Purpose: Hypopharyngeal cancer is diagnosed at the advanced stage in most cases, which the prognosis known to be poor. Thus, the efficacy of induction chemotherapy followed by radiotherapy, with regards to the response and survival rate for stage IV hypopharyngeal cancer patients, was examined. Materials and Methods: From July 1998 to February 2000, 18 cases were diagnosedas AJCC stage IV hypopharyngeal cancer without distant metastasis. These patients were treated with induction chemotherapy followed by radiotherapy, and the results retrospectively analyzed. The regimen of the induction chemotherapy was the 5-FU and cisplatincombination, at 3-week intervals for, 2 cycles. The total radiation dose for the primary lesion and metastatic lymph nodes was $68.4\~72.0$Gy (median: 70.2 Gy). Results: The: The median follow up period was 28 months, ranging from 7 to 99 months. The 3-year overall survival and disease-free survival rate were 41.7 and $31.1\%$, respectively. In 6 cases ($33.3\%$), conservation of the larynx for over 3 years was possible. After the induction chemotherapy there were 16 partial responses ($88.8\%$), 1 complete response and 1 with no response ($5.6\%$ each), therefore, 17 of the 18 cases ($94.6\%$) showed responses. After the completion of the induction chemotherapy and radiotherapy, a complete response was noted in 13 cases ($72.2\%$), a partial response in 5 ($27.8\%$), with an overall response rate of $100\%$. In the analysis of the prognostic factors influencing the survival rate, the 3-year and disease-free survival rates for the complete and partial response groups were 43.1, and $20.0\%$, and 39.6, and $20.0\%$, respectively (p=0.0003, p=0.002). Only the final response after treatment completion was statistically significant. Conclusion: For stage IV hypopharyngeal cancer, induction chemotherapy followed by radiotherapy was an effective treatment, with no severe side effects. 목적: 하인두암은 대부분 진행되어 진단이 되며 예후가 불량한 것으로 알려져 있다. 이에 4기 병기 하인두암에서 선행 항암화학요법 후 방사선치료를 시행하여 반응과 생존율에 미치는 영향을 알아보고자 하였다. 대상 및 방법: 1989년 7월부터 2000년 2월까지 원격전이가 없었던 AJCC 병기 4기의 하인두암으로 진단되어 선행 항암화학요법후 방사선치료를 받았던 18예를 대상으로 후향적 분석을 하였다. 선행화학요법은 5-FU와 cisplatln을 병용하여 3주 간격으로 모든 환자에서 2회 시행하였다. 총방사선량은 원발병소와 전이된 임파절에 $6834\~72.0$Gy까지 조사하였다(중앙값: 70.2 Gy). 결과: 추적관찰기간은 7개월에서 99개월이었다(중앙값 28개월). 3년 생존율 및 무병생존율은 각각 $41.7\%$, $31.1\%$였다. 6예($33.3\%$)에서 3년 이상 후두 보존이 가능하였다. 선행 항암화학요법 후 16예($88.8\%$)에서 부분관해를 보였고, 완전관해, 무반응은 각각 1예($5.6\%$)에서 관찰되었다. 모든 치료가 끝난 후 치료 반응으로 완전관해는 13예($72.2\%$) |
