Purpose : The purpose of this study was to evaluate the efficacy of curative radiotherapy in the management of supralottic cancer. Materials and Methods : Twenty-one Patients with squamous cell carcinoma of the supralottis were treated with radiotherapy at Gyeongsang National University Hospital between 1590 and 1994. Median follow-up period was 36 months and 95% were observed for at least 2 years. Results : Actuarial survival rate at 5 years was 39.3% for 21 patients. The 5-rear actuarial survival rate was 75.0% in Stage I, 42.9% in Stage II, 33.3% in Stage III and 28.6% in Stage IV(p=0.54), The 5-year local control rate was 52.0% for 21 patients. The 5-rear local control rate was 75.0% in Stage I, 57.1% in Stage II, 66.7% in Stage III, and 28.6% in Stage IV(p=0.33). Double primary cancer was developed in 3 patients and those were all esophageal cancers. Conclusion : In early stage(Stage I and II) supralottic cancer, curative radiotherapy would be a treatment of choice and surgery would be better to be reserved for salvage of radiotherapy failure. In advanced stage(Stage III and IV), radiotherapy alone is inadequate for curative therapy and combination with surgery should be done in operable patients. This report emphasizes the importance of esophagoscopy and esophagogram at the follow-up of patients with supralottic cancer.

배경: 흉선암은 드문 질환으로 치료경과 및 예후가 침윤성 흉선종에 비해 나쁜 것으로 알려져 있으며 병기의 분류나 병기에 따른 치료방법이 아직 표준화 되어있지 않아 치료에 어려운 점이 있다. 이에 본교실에서 흉선암으로 진단되었던 환자들의 피료방법 및 성적을 분석하여 그 결과를 보고하고자 한다. 대상 및 방법: 계명대학교 동산의료원 흉부외과학교실에서는 1984년 8월에서 흉선암으로 진단되었던 8례의 환자를 대상으로 의무기록을 참고하여 병기에 따른 치방법료 및 예후 등을 후향적으로 분석하였다. 결과: 연령은 23세에서 67세까지로 평균 46세였으며 전흉부통증이 주증상이었다. 조직학적으로는 임파상피양암(lymphoepithelioma-like carcinoma)이 2례, 편평상피암(squamous cell carcinoma)이 2례, 기저세포암(basaloid carcinoma)이 1례, 혼합형(mixed type)이 3례 있었다. 임상적 병기분류는 Masoka의 분류법을 사용하였으며 제I기 2례, 제II기 4례, 제III기 1례, 제IVAr기가 1례 있었다. 4례의 환자에서는 종양의 완전적출이 가능했으며 3례에서는 고식적 수술을 시행하였다. 1례의 환자는 주위조직으로의 침윤과 심낭에 퍼져있어 조직생검만을 시행하였다. 전례에서 보조적 항암치료를 받았고 술후 병기가 제III기 이상이거나 종양의 절제가 불완전했던 5례의 환자에서는 보조적 방사선치료를 병행하였다. 이들 중 5례에서 술후 보조적 항암치료 및 방사선치료를 받고 현재까지 생존해있다. 평균추적기간은 55.3$\pm$64.6 개원이었고, 3례의 환자는 사망하였으며 4례의 환자는 종양의 재발증거 없이 생존해있다. 결론: 종양의 조기진단과 완전종양적출후 적극적인 보조적 항암치료 및 방사선치료가 흉선암을 치료하는데 도움이 될 것으로 사료된다.

Background : Lung cancer continues to be the leading cause of cancer death in the United States and it's incidence has been rapidly increasing in Korea, too. The overall cure rate for non-small cell lung cancer(NSCLC) is approximately 10%, and the cure is generally achieved by surgery. Unfortunately, however, less than 15% of all patients and less than 25% of those who present with localized disease are candidates for curative surgical resection. So preoperative staging evaluation followed by curative resection has a major role in determining the long tenn prognosis of NSCLC patients. Therefore, we have conducted this study to compare pre-operative and post-operative staging and the long-tenn relapse-free survival rates in NSCLC patients according to its stage. Methods : We analyzed the medical records of 217 NSCLC patients who were operated on for curative resection in Seoul National University Hospital, retrospectively. Among them, 170 patients who were completely resected were selected to determine the long term relapse-free survival rates. Results : Among 217 NSCLC patients, men were 157 and women were 30. The median age was 58 and the difference between men and women was not found. The discrepancy rate between preoperative and postoperative staging was 40.1%. Its major cause was due to the difference of nodal staging. The 3-year relapse-free survival rates were 73%, 53% and 48% in stage I, II and IIIa, respectively. There was no difference of relapse-free duration in recurred patients according to the stage or histologic types. Conclusion : The postoperative pathologic staging determines the long tenn prognosis of patients with NSCLC after surgery, but current preoperative clinical staging can not predict the postoperative pathologic staging correctly. So the improved modality of staging system is required to predict the pathologic staging more correctly.

Forty-two preoperative CT scans with renal cell carcinoma were reviewed and compared with pathologic findings to evaluate the differential points between stage I and II. Regardless of whole body staging, perirenal fat infiltrations were seen in 9 cases and the other 33 cases showed no infiltration onto perirenal fat tissue. We retrospectively reviewed them by comparing tumor size and CT findings, following three view points, lobulating contour of tumor margin, thickening of Gerota's fascia and strands in perirenal fat tissue. The size of them was 2-15 cm, size of the stage I tumors was 2-15 cm and that of stage II was 6-15 cm. In stage I(n=33), 25 cases(76%) showed smooth margin, and the others(n=8) showed lobulating contours. Thickening of Gerota's fascia was observed in 7 cases(21%) and strands in perirenal fat tissue in 14(42%). Of these, only one positive finding was seen in 7 cases(21%), 2 findings in 6(18%), 3 findings in 3 (9%) and nothing in 17cases(51%). In stage II(n=9), 3 cases(34%) showed smooth margin, and the others(n=6) showed lobulating contours. Thickening of Gerota's fascia were observed in 5 cases(55%) and strands in perirenal fat tissue in 9(100%). Of these, one finding was seen in 2 cases(22%), 2 findings in 3(33%), 3 findings in 4 (44%). In conclusion, it is insufficient to evaluate the perirenal fat infiltration in renal cell carcinoma with only one positive finding of 3 view points; lobulation of tumor margin, thickening of Gerota's fascia, strands in perirenal fat tissue. But if all these findings are shown, it is helpful to determinate perirenal fat infiltration of renal cell carcinoma.

Purpose : To evaluate effect and tolerance of external beam radiotherapy for carcinoma of the prostate and define the optimal radiotherapeutic regimen. Materials and methods : We retrospectively analyzed the records of 60 patients with prostate cancer who were treated with external beam radiotherapy with curative intent in our institution between September, 1987 and March, 2000. Histologic diagnosis was established by transurethral resection or ultrasonography guided biopsy. The major presenting symptoms were a nodule at routine prostatic examination and frequency and urgency of urination, along with dysuria. The median age was 63 years with range of 51 to 87 years. There were 6 patients in Stage A, 20 in Stage 8, 26 in Stage C, and 8 in Stage Dl. All patients were treated with megavoltage equipment producing 10 MV photons. The 4 field pelvic brick technique was used to a dose of 45 Gy or 50.4 Gy at 1.8 Gy per day in 5 to 6 weeks, after which a small boost field was delivered 2.0 Gy per day to a total dose of 66 to 70 Gy. The follow-up period ranged from 1 to 8 years. Results : Actuarial 5-year and 7-year survival rates for Stage A, B, C, and D1 were $100\%\;and\;84\%$, $83\%\;and\;72\%$, $67\%\;and\;54\%$, and $v$, respectively. The corresponding 5-year and 7-year relapse free survival rates were $84\%\;and\;84\%$, $77\%\;and\;67\%$, $48\%\;and\;40\%$, and $33\%\;and\;25\%$, respectively. Relapse free 5-year survival rates for Stage B were $80\%,\;80\%,\;and\;50\%$ for well, moderately, and poorly differentiated tumors, respectively. These were $64\%,\;44\%,\;and\;33\%$ for Stage C, respectively. The local control rates at 5 years were $84\%,\;85\%,\;78\%,\;and\;60\%$ for Stage A, B, C, and D1, respectively. Mild to moderate complications were observed in $22\%$ of patients. Severe complications requiring surgical procedures were documented in only $3\%$ of patients. Conclusion : This study confirms that external beam irradiation is an effective and safe treatment for prostatic cancer, providing long-term local control and good survival with acceptable complications.

Purpose: We analyzed cases of advanced gastric cancer (AGC) by using two nodal stagings, UICC and Japanese systems. We also analyzed cases of UICC N3M0 by different ways to see which nodal system or group had better prognostic power. Materials and Methods: From Feb. 1990 to May 2000, 197 UICC M0 patients of AGC who had undergone curative resection were analyzed by using the nodal stagings of the UICC and the Japanese systems. Also, 58 patients with UICC N3M0 gastric cancer were analyzed by using the Japanese n-staging, metastatic ratio and the metastatic number Results: The 5-year survival rates were 62.9%, 33.0% and 21.2% for UICC N1, N2 and N3, and 61.2% and 25.3% for Japanese n1 and n2, respectively in patients of N3M0 AGC, the 5-year survival rates were 62.5% for Japanese n1, and 33.0% and 22.9% for metastatic ratios of less than 0.5 and metastatic numbers below 26, respectively significantly better than the 5-year survival rates for higher ratios and numbers (P=0.018, 0.021). Conclusion: UICC N staging of gastric cancer has better prognostic power with differentiation between stages than Japanese n staging. In patients with UICC N3M0 gastric cancer, the metastatic ratio and the metastatic number, as well as the Japanese n staging, were valuable prognostic factors.
