Nasal fossae 의 암이란 비강과 부비동들에서 발생하는 것으로서 환자를 가장 괴롭히며 또한 가장 믿을수 없는 악성종양들중의 하나이다. 비록 본 예수병원 암환자 등록부에 의하면 전 암환자의 2.2% 발생빈도로서 주요한 발생빈도를 보이지는 않지만, 이 부위의 암을 치유하는데는 세심하고 철저한 모든 진단적 검사와 과감한 외과 및 치료방사선의 병합치료가 요구된다. 저자들은 지난 22 년간 비강 및 부비동 (Nasal fossae) 에서 발생한 원발성 악성종양중 치유목적의 근치수술을 시행한 68 예를 임상고찰 하였다. 근치수술을 시행했던 68 예중 91% 에서 제 3 병기 또는 4 병기의 진행된 경우 이었다. 외과적 수술은 한예의 사골동 (篩骨洞) 종양적출술 및 부분상악동(上顎洞)절제술 한 예를 제외한 66 예 모두에서 전상악동(全上顎洞)절제술 (total maxillectomy) 또는 확장 전상악동(全上顎洞)절제술 (extended total maxillectomy) 을 시 하였다. 저자들은 역학적(疫學的), 병리학적(病理學的), 병기(病期) 및 치료, 재발율과 생존율들을 분석 고찰하였으며 3가지 치료형태를 서로 비교하였다. 즉 수술만 시행한 군, 수술전 방사선 치료 및 수술병합군, 수술과 수술후 방사선치료 병합 군으로 나눴다. 저자들의 예비적 (preliminary) 관찰 결과는 2 년간 무병생존율 (disease-free 2-year survival) 만을 볼때, 수술만 시행한 군에서 40%로써 통계학적으로는 가장 좋았으나 실제는 수술만 시행한 군에서는 단지 40%만이 제 4 병기(病期)의 진행된 경우였으나 수술전 방사선치료 또는 수술후 방사선치료등의 병합치료에서는 제 4 병기(病期)의 진행된 상태가 무려 60 %나 되었다. 전체적인 재발율 (Overall recurrence rate) 은 68.2%로써 무서울 정도로 높았으며 전체적인 2 년 무병율은 23.7%였다. 저자들은 이 분야에서 실패의 원인분석과 치료방법의 선택등에 대한 지침을 제시하고저 한다.

Purpose :We conducted a prospective non-randomized clinical study to evaluate the efficacy and toxic of the preoperative concurrent chemoradiotherapy for locally advanced unresectable rectal cancer. Materials and Methods: Between January 1995 and June 1998, 37 conecutive patients with locally unresectable advanced rectal cancer were entered into the study. With 3- or 4- fields technique, a total of 45 Gy radiation was delivered on whole pelvis, followed by 5.4 Gy boost to the primary tumor in some cases. Chemotherapy was done at the first and fifth week of radiation with bolus i.v. 5-Fluorouracil (FU) 370$\~$450 mg/m$^{2}$, days 1$\~$5, plus Leucovorin 20 mg/m$^{2}$, days 1$\~$5. OF 37 patients, 6 patients did not receive all planned treatment course (refusal in 4, disease progression in 1, metastasis to lung in 1). Surgical resection was undergone 4$\~$6 weeks after preoperative concurrent chemoradiotherapy. Results :Complete resection rate with negative margins was 94$\%$ (29/31). Complete response was seen in 7 patients (23$\%$) clinically and 2 patients (6$\%$) pathologically. Down staging of tumor occured in 21 patients (68$\%$). Treatment related toxicity was minimal except grade III & IV leukopenia in 2 patients, respectively. Conclusion : Preoperative concurrent chemoradiotherapy in locally advanced rectal cancer was effective in inducing down staging and complete resection rate. Treatment related toxicity was minimal. Further follow up is on-going to determine long term survival following this treatment.

Purpose: The incidence of gastric neoplasms is increasing in the elderly population, and a rational method of treatment for gastric cancer in the elderly is needed to improve survival. The purpose of the present study was to clarify whether the patient's age is an independent prognostic factor and to determine clinicopathological characteristics in the elderly. Material and Methods: Curative or palliative surgery for gastric cancer was carried out on 706 patients in Chosun University Hospital from March 1995 to February 2002. They were divided into the following two groups: elderly group (75 years or older) and control group (under 74 years old). The clinicopathologic features of these patients were reviewed retrospectively, and a multivariate analysis was performed. Results: There was no difference in clinicopathological appearances between the two groups, and the postoperative morbidity and mortality rates were similar in the two groups. The two groups showed similar survival rates. Conclusion: In this study, age was not a prognostic factor in surgery for gastric cancer. In the elderly, an oncologically correct surgical procedure can safely be prosecuted with satisfactory early and late results.

The cholesteatoma is usually associated with chronic purulent otitis media and destroys the surrounding structures and may cause dangerous complications. The cholesteatoma with a positive fistula sign may be observed occasionally, if a softened area is formed in the bony capsule over a semicircular canal which exposed the membranous structure of the canal. Recently, the authors have experienced a case of cholesteatoma combined with labyrin thine fistula in a 22-year old male patient. We present this case with a brief review of the literatures.

In 1859, Billroth used the term "Zylindrome" to describe a tumor arising in the paranasal sinuses. This neoplasm has been referred to by a variety of terms including cylindroma, basaloma, basaloid adenoma, cribriform adenocarcinoma, and "adenoid cystic carcinoma", now preferred by most authors. It most often arises in the major and minor salivary glands of the head and neck but has been noted in the trachea, lung, breast, skin and elsewhere. The tumors are characterized by a high incidence of local recurrence and ultimate distant metastases after agrressive attempts at surgical excision. Radiation therapy, while not curative, has proved uniformly useful in promoting tumor regression and pain relief as a palliative treatment. The present study was undertaken to review our experience with a group of 44 patients with adenoid cystic carcinoma of the head and neck, diagnosed at the Jeonju Presbyterian Medical Center between 1963 and 1980. The results are as follows: 1. Forty-four cases of adenoid cystic carcinoma represented 40% of the malignant salivary gland tumors during the same interval. 2. The most common primary sites were palate(8 cases) and submandibular gland (8 cases). 3. Thirteen patients (31%) had tumors. that arose in the major salivary glands; 29 (69%), minor salivary glands. 4. Of the 44 patients, there were 21 males. and 23 females. 5. Age at diagnosis ranged from 19 to 78 years; the average age was 50 years. 6. The tumor size was more than 4cm to 6cm in its greatest diamension in 10 patients. Clinically positive cervical lymph nodes were found in 7 patients; distant metastasis in one case at the time of diagnosis. 7. Radical excision was employed in 27 patients, 14 of whom combined with radiotherapy. 8. Of 29 patients available for follow-up the gross and determinate 3-year survival rates were 27.6% and 44.4%, respectively. Among twelve patients who received radical excision, the 3-year survival was 58%. 9. Ten of these 44 patients had local recurrence in an interval of 3 to 88 months. from the initial treatment. Of ten recurrences, 3 occured after 5 years. 10. Distant metastasis was found in 3 of the treated patients. All were pulmonary metastasis.

Purpose : To evaluate the pathologic effects of preoperative radiotherapy o the resectable distal rectal cancer, we analyzed the results of postoperative pathologic findings for the patients with preoperative radiotherapy ant surgery Materials and Methods: From July 1995 to April 1996, we treated sixteen patients of resectable rectal cancer with preoperative radiation therapy and curative surgery At diagnosis, Thomas Jefferson (TJ) system was used for the clinical stage of the Patients. We treated the patients with conventional radiation therapy of 4500~5000cGy before surgery. The surgery was carried out 4 weeks after completion of radiation therapy. Modified Astler Coller (MAC) system was used for the postoperative pathologic stage. We analyzed the pathologic stages and findings according to preoperative clinical stage and compared with those of the control group in similar clinical stages. Result : All patients were treated with sphincter preservation surgery after Preoperative radiation therapy. Pathoiogic complete response (CR) was shown in 1 case $(6.3\%)$. We compared the results between preoperative radiation therapy group (Preop.RT group) and surgery only group (control group). In TJ stage II, among nine patients of Preop.RT group, 8 patients $(88.9\%)$ were in MAC stage 8 except 1 CR patient, but among 17 patients of control group. 11 patients$(64.7\%)$ were in MAC stage B and 6 Patients $(35.3\%)$ in MAC stage C. In TJ stage III, among 7 patients of Preop.RT group, 4 patients $(57.1\%)$ were in MAC stage B and 3 patients$(42.9\%)$ in MAC stage C. Among 14 Patients of control group, 4 patients $(28.6\%)$ were in MAC stage B and 10 Patients $(71.4\%)$ in MAC stage C. Above results showed that postoperative Pathologic stage was decreased in Preop.RT group with statistical significance (P=0.049). The postoperative Pathologic findings (blood vessel invasion. Iymphatic vessel invasion, perineural invasion) were decreased in the Preop.RT group compared with those of control group. But statistical significance was found only in Iymphatic vessel invasion (p=0.019). Conclusion : The Postoperative pathologic stages and adverse Prognostic pathologic findings were decreased in preoperative radiation therapy group. The Iymphatic vessel invasion and MAC stage C findings were abruptly decreased in Preoperative radiation therapy group. The preoperative radiation therapy was found to be effective in resectable rectal cancer. The patients group in our study was very small and long term follow up was not done. Therefore, further study about this issues is needed.

The experience with operative treatment for total correction of Tetralogy of Fallot at the department of Thoracic and Cardiovascular Surgery, Korea University Hospital from January, 1977, through April, 1983 was reviewed. Of the 29 patients reviewed, male to female occurrence ratio was 22:7 Type of V.S.D. was type II in 26 cases[90%] and total conus defect in 3 cases[10%]. Average size of V.S.D. was 19 mm. Type of Right ventricular outflow tract stenosis was highest frequency with pulmonary valvular and infundibular stenosis combined type in 21 cases[72%], and there were 8 deaths In this group. Type of R.V.O.T. reconstruction contains 2 cases of infundibulectomy only, 1 case of infundibulectomy with valvular commissurotomy, 2 cases of pericardial patch, 23 Cases of pericardial patch with Teflon or Dacron felt reinforced and 1 case of pulmonary valved conduit reconstruction. Operative mortality was higher in outflow patch through pulmonary valve ring. Overall mortality was 31%. Major causes of death and postoperative complications were low output syndrome, complete A-V block acute renal failure, ventricular fibrillation, bleeding brain abscess, and sudden cardiac arrest.
