A simple Intracavitary irradiation of carcinoma of the nasopharynx has been found useful as a supplementary radiation boost to the primary site, and as a method of re-irradiation for recurrence in the nasopharynx. Hopefully, local tumor control can be enhanced by employing this technique.

Between January 197l and December 1987, 113 patients with nasopharyngeal cancer (NPC) were treated by radiation therapy with or without chemotherapy in the department of Radiation Oncology, Yonsei University Hospital. There were 19 patients under thirty years of age. The histology was undifferentiated carcinoma in $68\%$ of the younger patients as compared to $47\%$ of the older patients. Sex, stage, initial symptoms and treatment modalities differed little from those of older patients. In younger patients, the initial complete response rate was $79\%$ as compared to older patients with $54\%$, distant metastases were more common and the overall five year survival rate was not significantly different between the two age groups ($33.7\%$ for the young vs. $37.4\%$ for the old). The five year survival rates for stage III and IV were $60.0\%$ and $24.5\%$, respectively. Histologic subtype was not correlated with survival. The best survival was found only in patients who obtained a complete clearance of disease after radiation therapy.

비인강암은 비인강상피에 발생한 암으로 경부전이 및 간, 폐, 뼈 등의 원격전이가 흔히 나타난다. 본 증례에서는 제 4기 병기를 가진 비인강암환자에서 항암 화학요법 및 방사선 치료 후 매우 드물게 후경부 및 액와 림프절 전이를 보인 환자를 보고하는 바이다. 진행된 병기를 보이는 비인강암 환자는 방사선 치료 후 피부전이가 종종 나타나는 현상이나 후경부 림프절 전이는 흔치 않다. 특히 액와 림프절 전이는 비인강암에서 거의 전이를 보이지 않으나 본 증례에서는 매우 드물게 액와 림프절 전이를 보여 보고하는 바이다.

연구방법 : 근치적 목적의 동시항암방사선치료를 시행받은 비인강암 환자들을 대상으로하여 치료 효과와 독성에 대한 후향적 분석을 시행하였다. 환자 및 방법 : 1993년 8월부터 1999년 3월까지 원격전이가 없는 50명의 비인강암 환자들이 방사선 치료기간 중 주 1회의 시스플라틴 $20mg/m^2$을 투여받았고, 1999년 4월부터 2000년 4월까지 20명의 환자가 상기 용량의 시스플라틴에 더하여 경구용 UFT300mg을 추가적으로 투여받았다. 총 70명 환자들의 임상기록과 병리 기록지를 검토하였다. 결 과: 연령의 중앙값은 47세 (범위 $18{\sim}76$)였고, 남자와 여자가 각각 53명과 17명 이었으며, 병기 II, III, IVA, IVB가 각각 23명, 14명, 15명, 18명이었다. 치료에 대한 반응율은 92.8%(95% C.I. $42{\sim}143%$)였고(완전반응 57명, 부분반응 8명), 총 34개월의 추적 관찰 기간 동안에 완전반응을 보인 57명 중 21명에서 재발(국소재발 5, 원격전이 11, 복합전이 5)을 하였다. 3년 무진행 생존율은 51.5%였으며 5년 생존율은 60.3%였다. 경구용 UFT의 추가적 사용은 주 1회 시스플라틴 항암치료에 비하여 반응율과 생존율 및 독성에 유의한 영향을 미치지 않았다. 결 론: 주 1회 저용량 시스플라틴$\pm$경구용 UFT를 이용한 동시항암방사선요법은 비인강암 환자의 치료에 있어서 비교적 적은 독성으로 높은 반응율을 나타내었으나, 향후 재발율을 감소시키기 위한 연구가 지속되어야 할 것으로 사료된다.

Purpose : The objective of this study was to determine whether the expressions of the two components of DNA-dependent protein kinase, Ku70 and DNA-PKcs, influence the response to radiotherapy (RT) and outcome of treatment of non-disseminated nasopharyngeal carcinoma (NPC) in patients who received definitive RT. Materials and Methods : Sixty-six patients with NPC who were treated with radiotherapy alone or with concurrent chemotherapy between June 1995 and December 2001 were divided into groups based on the levels of immunoreactivity for Ku70 and DNA-PKcs in pretreatment biopsy specimens. The over-expression of Ku70 or DNA-PKcs groups Included patients whose biopsy specimens showed at least 50% immunopositive tumor cells; patients in which less than 50% of the tumor cells in the biopsy tissues were immunopositive were placed in the low Ku70 and DNA-PKcs groups. The immunoreactivities for Ku70 and DNA-PKcs were retrospectively compared with the sensitivity of the tumor to radiation and the patterns of therapy failure. Univariate analyses were peformed to determine the prognostic factors that influenced locoregional control of NPC. Results : The five-year locoregional control rate was significantly higher in the low Ku70 group (Ku(-)) (85%) than in the high Ku70 group (Ku(+)) (42%) (p=0.0042). However, there were no differences in the metastases-free survival rates between the two groups (Ku70 (+), 82%; Ku70 (-), 78%; p=0.8672). Univariate analysis indicated that the over-expression of Ku70 surpassed other well-known predictive clinocopathologic parameters as an Independent prognostic factor for locoregionai control. Eighteen of 22 patients who had locoregional recurrences of the tumor displayed an over-expression of Ku70. No significant association was found between the level of DNA-PKcs expression and the clinical outcome. Conclusion : Our data suggest that the level of Ku70 expression can be used as a molecular marker to predict the response to RT and the locoregional control after RT and concurrent chemotherapy in patients with non-disseminated NPC.
