목적 : 국소진행된 두경부종양 환자에서 방사선감작제로서 cisplatin을 방사선치료와 동시병용하였을때, 반응율과 독성을 알아보고 국소재발율 및 단기생존율을 분석해 보고자 하였다. 대상 및 방법 : 1995년 1월부터 1998 8월까지 AJCC 병기 II-IV의 국소진행된 두경부종양으로 근치적방사선치료중 cisplatin 동시화학요법을 받은 환자 29명을 대상으로 하였다. 비인강암이 16예였고 구인두암이 5예, 하인두암과 후두암이 각각 4예씩이었다. 대상환자의 연령분포는 22세에서 74세로 중앙값은 56세였고 남녀비는 22:7이었다. 방사선치료는 6 MV와 15 MV X선 및 $9\~14\;MeV$전자선을 사용하여 원발병소와 전이된 임파절에 총 $7,000\~7,560\;cGy$ (중앙값 7,020 cGy)까지 조사하였다. Cisplatin은 $100\;mg/m^2$을 방사선치료와 동시에 매 3주 간격으로 3회까지 투여하는 것을 원칙으로 하였다. 결과 : 치료에 대한 반응율은 완전관해가 21예$(72.4\%)$, 부분관해가 5예$(17.2\%)$, 경미한 반응이 3예$(10.4\%)$로 나타났다. 치료 후 잔여임파절병변에 대한 경부곽청술이 2예에서 시행되었다. 추적관찰기간($5\~55$개월, 평균 37개월)중 8례에서 원발병소 혹은 임파절에서 재발하여 국소재발율은 $27.6\%$였고, 원격전이가 4예$(13.8\%)$에서 관찰되었다. 3년무병생존율은 $60\%$였으며 원발병소가 비인강암인 경우나 치료에 완전반응을 보였던 경우가 무병생존율이 유의하게 높은 것으로 나타났다. 치료에 다른 급성독성으로 10예$(34.5\%)$에서 grade 3의 점막염, 5예$(17.2\%)$에서 grade 3의 백혈구감소증이 관찰되었다. 전체 환자 중 21예$(72.4\%)$가 3회의 Cisplatin 화학요법을 완료하였다. 3예에서는 grade 3의 백혈구 감소증, 2예는 전신상태불량으로 cisplatin이 2회만 투여되었고, 다른 3예는 신기능이상 및 신경독성으로 인해 치료중간에 5-FU로 대치되었으며, 전체치료기간이 2주 이상 지연되는 major deviation은 3예$(10.3\%)$에서 관찰되었다. 결론 : 국소진행된 두경부 종양환자에서 Cisplatin을 근치적방사선치료와 동시에 병용하는 치료전략은 비교적 높은 치료반응율, 국소제어율 및 생존율을 나타내었다. 급성치료독성의 빈도가 높았으나 치료에 대한 순응도는 비교적 양호하였다. 향후 좀더 많은 증례의 수집 및 장기추적관찰과 함께 원발병소에 따른 독립적인 연구가 필요할 것으로 사료되었다.

Purpose : This study tried to evaluate the effectiveness of combined treatment using radiation therapy and concurrent cisplatin as a radiosensitizer in the management of locally advanced head and neck cancer. Materials and methods : From January 1995 to August 1998, 29 evaluable patients with locally advanced head & neck cancels (AJCC stage $II\~IV$) were received curative radiation therapy $(total\;70\~75.6\;Gy/35\~42\;fractions,\;1.8\~2\;Gy/fraction)$ and concurrent cisplatin chemotherapy ($100\;mg/m^2$, D1, D22, D43). The neck dissections were peformed for residual lymphadenopathy. Follow-up ranged from 5 to 55 months (median 24 months). Results : Twenty-one $(72.4\%)$ patients achieved clinical complete responses. The partial response and minimal response rates were $17.2\%\;and\;10.4\%$, respectively. Locoregional failure rate was $27.6\%$, and included 6 patients with local failures, 4 patients with regional failures, and 2 patients with combined local and regional failures. Four of 29 patients $(13.8\%)$ developed distant metastasis. The disease free survival rate at 3 years was $60\%$. Nasopharyngeal primary tumors or complete responders showed significantly higher disease free survival rate. The grade 3 mucositis and nausea/vomiting was noted in $34.5\%$, respectively. Major prolongation of radiation therapy duration was inevitable in three patients. Twenty-one patients $(72.4\%)$ completed 3 courses of cisplatin and 5 patients received 2 courses of cisplatin. Three patients received only one course of cisplatin due to nephrotoxicity and neurotoxicity, and then changed to 5-FU regimen. Conclusions : Concurrent cisplatin-radiation therapy in locally advanced head and neck cancer showed high response rate, reasonable locoregional control, and survival rate. As expected, acute toxicities were increased, but compliance to treatment was acceptable. Assessment of the effect of the combination in this setting requires further accrual and follow-up.

The endpoints of the study included the initial tumor response, toxicity, locoregional failure rate, distant metastasis rate, prelinrinaiy disease free and overall survival rates. The RTOG/EORTC toxicity grading system was used.
This study tried to evaluate the effectiveness of combined treatment using radiation therapy and concurrent cisplatin as a radiosensitizer. The endpoints included toxicity, response rate, locoregional control and preliminaiy survival outcomes.
For patients with advanced stage laryngeal cancer that would require total laryngectomy, a three-arm intergroup trial (RTOG 9111, ECOG 9111 and SWOG 9201) is in progress to determine the best organ preservation approach. This trial randomizes patients to receive induction cisplatin and 5-FU chemotherapy followed by radiotherapy; concurrent cisplatin (100 mg/m2 on day 1, 22, 43) plus radiotherapy; or radiotherapy alone. The other ongoing intergroup trial includes patients with locally advanced, unresectable cancer of hypopharynx, orophaiynx, oral cavity or larynx who are randomized to receive conventional radiotherapy; concurrent cisplatin plus conventional radiotherapy; or concurrent cisplatin/ 5-FU chemotherapy plus split-course radiotherapy.
