Objective: To compare the clinical effects of concurrent radiochemotherapy with those of radiotherapy in treating locally advanced nasopharyngeal carcinoma (Stage III~IVa). Methods: A total of 95 patients suffering from nasopharyngeal carcinoma (Stage III~IVa) were divided into two groups: concurrent radiochemotherapy (Group CCRT, n=49) and radiotherapy (Group RT, n=46). The two groups were both delivered conventional fractionated radiotherapy, while Group CCRT also received three cycles of PF (DDP+5-Fu) or PLF (DDP+5-Fu+CF) chemotherapy. Results: The complete remission rate and total remission rate of Group CCRT were higher than those of Group RT ($X^2$=4.72~7.19, P<0.05). The one-year overall survival (OS) rate calculated by the life table method, was also higher than that of Group RT ($X^2$=4.24, P<0.05) as well as the 3-year OS rate, nasopharyngeal control rate and cervical lymph nodes' control rate ($X^2$=4.28~4.40, P<0.05). In addition, the 5-year OS and metastasis-free rates of Group CCRT were higher than those of Group RT and the differences were of statistical importance ($X^2$=3.96~8.26, P<0.05). However, acute toxicity was also obviously higher, the difference in gastrointestinal reactions being statistically significant ($X^2$=11.70, P<0.05). Conclusion: This study demonstrated that concurrent radiochemotherapy could improve the remission rate, overall survival rate and locally control rate. The toxicity of concurrent radiochemotherapy could be tolerated by the patients.

Background: Supraglottic and hypopharyngeal regions drain into the upper deep cervical lymph nodes. And bilateral neck node metastasis is frequently occured especially, in the early stage. It influences on the prognosis of above diseases. The prognosis for patients wih supraglottic and hypopharyngeal cancers, although usually poor, has improved by modern imaging technique, better application of treatment modalities, increasing assortment of reconstructive procedures and improved application of radiation therapy. Objectives: This study was designed to obtain objective data about the patterns of neck node metastasis and to identify the necessity of elective bilateral neck dissection. Material and Methods: Twenty four patients with supraglottic cancer and twenty six patients with hypopharyngeal cancer were investigated from the chart review. Results: In supraglottic cancer, the most frequent sites of neck metastasis is level II (52.9%) and level III (52.9%) in ipsilateral side, level II (29.4%) in contralateral side, in hypopharyngeal cancer, level II (73.7%) and III (52.6%) in ipsilateral side, level II (10.5%) in contralateral side. In elective neck dissection, the occult metastasis is about 50% in supraglottic cancer, but there is no occult metastasis in hypopharyngeal cancer. Conclusion: In supraglottic cancer, elective bilateral neck dissection is necessary because of early contralateral neck metastasis, but in hypopharyngeal cancer, elective contralateral neck dissection may not be always necessary because of rare occult metastasis and contralateral neck metastasis.

Sjögren's syndrome (SS) is a chronic inflammatory autoimmune disorder that affects mainly salivary and lacrimal glands, but its cause remains largely unknown. Clinical data indicating that SS occurs in a substantial proportion of patients with lupus points to common pathogenic mechanisms underlying the two diseases. To address this idea, we asked whether SS develops in the lupus-prone mouse strain sanroque (SAN). Owing to hyper-activation of follicular helper T (Tfh) cells, female SAN mice developed lupus-like symptoms at approximately 20 wk of age but there were no signs of SS at that time. However, symptoms typical of SS were evident at approximately 40 wk of age, as judged by reduced saliva flow rate, sialadenitis, and IgG deposits in the salivary glands. Increases in serum titers of SS-related autoantibodies and numbers of autoantibody-secreting cells in cervical lymph nodes (LNs) preceded the pathologic manifestations of SS and were accompanied by expansion of Tfh cells and their downstream effector cells. Thus, our results suggest that chronic dysregulation of Tfh cells in salivary gland-draining LNs is sufficient to drive the development of SS in lupus-prone mice.

이식후 발생하는 림프증식성 질환(PTLD)은 양성 다크론성 B림프구 증식증으로부터 악성의 단크론 림프종에 이르기까끼 다양한 임상상을 보이는 질환이다. PTLD는 Epstein-Barr virus(EBV)와 과도한 면역억제와 밀접한 관계가 있다. 국내에서는 1997년 성인에서 신 이식 후 발생한 예가 처음 보고되었으며, 소아에서는 간 이식 후 발생한 예가 있을 뿐 신 이식 후 발생한 증례의 보고는 없어 이 보고가 국내 최초로 신이식 소아에서 발생한 PTLD 증례이다. 환자는 9세 남아로서 긴이식후 4개월후에 PTLD가 발생하였으며 주된 임상 양상은 발열, 림프절 종대와 혈변이었다. 림프절과 대장의 생검조직 에서 EBV in situ hybridization이 양성이고, 조직학적으로 B 세포계열의 PTLD에 합당한 소견이었다. 모든 증상은 면역억제제 감소와 ganciclovir 치료로 완전 관해되었다.

연구배경: 결핵성 경부 림프절염은 우리나라에서 폐결핵만큼 빈도가 높은 질환이다. 이 질병에서 수지상돌기세포는 초기의 항원 제시역할을 하고 있다. 그러나 림프절염의 임상 양상과 관련된 항원제시세포의 역할은 아직 명확하게 밝혀져 있지 않은 상태이다. 경부 림프절의 수지상 돌기세포의 침윤과 임상양상과의 연관성을 알아보기 위해 본 연구를 시행하였다. 방 법: 환자들의 입원기록 및 방사선사진을 바탕으로 후향적으로 고찰하였다. 72례의 조직표본을 대상으로 항산균도말염색을 다시 시행하였고, 수지상돌기세포의 단클론항체로 S-100b를 이용하여 면역조직 화학염색을 시행한 후, 각각 결핵성 육아종안의 수지상돌기세포의 수를 세어 비교분석하였다. 결 과: 결핵성 경부 림프절염이 있는 환자들의 30%가 폐결핵의 과거력이 있거나 현재 폐결핵을 앓고 있는 상태이었고 21%의 환자에서 항산균도말염색양성을 보였다. 이들 한 육아종안에 침윤된 수지상돌기세포의 수는 평균 $113.0{\pm}7.0$개이었다. 육아종내 수지상돌기세포의 침윤수가 증가됨에 따라 발열과 기침의 빈도는 감소하였고 항산균도말염색상에서 결핵균의 수가 더 감소하는 결과를 보였으며, 다중로짓회귀분석을 보면, 수지상돌기세포의 침윤은 특징적으로 발열에 기여하여하는 것으로 나타났다. 결 론: 수지상돌기세포가 결핵성 경부 림프절염에서 발열과 기침 등의 전신증상을 줄이고, 결핵균의 침윤정도를 감소시키는 것으로 확인되었고, 이는 수지상돌기세포가 Mycobacterium tuberculosis의 감염을 조절하고 이와 함께 면역반응도 조절하여, 결핵성 경부 림프절염에서의 임상양상을 결정하는 것으로 생각된다.

목 적 : KD는 주로 동양의 젊은 성인 여성에게서 경부 림프절 종대로 발현하는 것이 특징이며 수개월 내에 자연 치유되는 양호한 경과를 가지는 질환이다, 저자들은 KD로 진단된 소아환아의 임상적 특징을 알아보고, 환아들의 림프절 조직에서 바이러스 검출을 시도하여 KD와 HHV 8, EBV와의 연관성을 알아보기 위하여 본 연구를 시행하였다. 방 법 : 인제대학교 상계백병원에서 1998년 1월부터 2005년 12월까지 KD로 진단되어 치료받은 17세 이하 소아 26례를 대상으로 임상적 특징을 고찰하였다. 병력지 고찰을 통하여 후향적으로 분석하였고 추적 조사는 외래 병력 기록지와 전화 방문을 통하여 분석하였다. KD 환아의 림프절 조직으로부터 DNA를 추출하여 HHV 8 DNA를 검출하기 위해 PCR, EBV RNA를 검출하기 위해 ISH가 시행되었다. 결 과 : KD로 진단된 26명 중 남아 11례, 여아 15례로 성비는 1:1.4였고, 평균 연령은 13세였다. 환아의 연도별 분포는 2000년에 7례로 가장 많았으며, 여름에 가장 많이 진단되었다. 주증상은 발열(8/26)과 림프절의 동통(11/26)으로 발열의 기간은 평균 7.3일 이었다. 목빗근 뒷부위의 림프절 종대가 72%(18/24)였고 1례에서 경부 이외의 림프절 종대로 나타났다. 림프절의 크기는 $1cm{\times}1cm$에서부터 $6cm{\times}6cm$까지로 다양하게 나타났다. 백혈구 감소가 46%(6/13)에서 있었고 적혈구 침강 속도상승(>20 mm/hr)이 62%(8/13)에서 나타났다. 검체 확보가 가능하였던 20례 모두에서 HHV 8 DNA는 검출되지 않았으며, ISH를 이용한 EBV RNA 검사 결과도 음성이었다. KD 26례 모두 임상 경과는 양호하였으며, 1례(4%)만이 추적 중 발열과 함께 재발하였다. 전신성 홍반성 루프스를 포함한 결체 조직 질환으로의 이환은 관찰되지 않았다. 결 론 : KD는 소아에서 드물지 않게 발생하므로, 림프절 종대를 호소하는 환아에서 감별 진단에 포함되어야 한다. HHV 8과 EBV는 소아에서 진단된 KD의 원인 병원체로 작용할 가능성이 적을 것으로 생각된다.

Background and Objectives：Supraglottic partial laryngectomy is oncologically sound surgical procedure for selected cases of laryngeal cancer which maintains physiologic speech and swallowing without permanent tracheostoma. The purpose of this study is to evaluate the oncologic and functional results of supraglottic partial laryngectomy and neck dissection for supraglottic cancer. Materials and Methods：Between 1991-2005, Twenty-three supraglottic cancer patients, underwent supraglottic partial laryngectomy, were studied retrospectively. There were 5 patients with cT1, 14 with cT2, 4 with cT3 and 11 patients with cN0, 1 with cN1, 10 with cN2, 1 with cN3. All patients underwent neck dissection and postoperative radiotherapy was added to twenty patients. They were reviewed with respect to primary subsites, extended subsites, treatment result, survival rate, factors affecting the prognosis, postoperative complication, time of decannulation and oral diet, and postoperative voice. Results：Among eleven patients with clinically negative node, six patients had pathologically positive nodes. So occult metastasis was 54.5%. Two patients recurred at cervical lymph node and one had distant metastasis to lung. Local and regional control were 100% and 91.3%. The overall 3-year and 5-year survival rate were 84%, 78%, respectively. Nineteen cases were squamous cell carcinomas and four were basaloid squamous cell carcinomas. Basaloid subtype was significantly affected to survival. Decannulation and oral feeding were possible in 100%. Conclusions：Supraglottic partial laryngectomy is oncologically safe and functionally good procedure in supraglottic cancers. Elective neck dissection is beneficial in management of occult cervical metastasis.

One hundred fifty-four patients with the carcinoma of the uterine cervix were studied retrospectively to assess the result and impact of treatment at Department of Radiation Oncology, Korea University, Hae-Wha Hospital from Feb 1981 through Dec. 1986. Prior to radiotherapy, the patients were evaluated and staged by recommendation of FIGO including physical examination, pelvic examination, cystoscopy, rectosigmoidoscopy, chest X-ray, IVP. Ba enema. Also, an additional pelvic CT scan was obtained for some of the patients. The patients were treated by radiotherapy alone or adjuvant postoperative irradiation; in case of radiation therapy only, whole pelvic irradiation was given with Co-60 teletherapy unit via AP and PA parallel opposing fields or 4-oblique fields, 180 cGy per day, 5 days per week and intracavitary insertion was performed. In satges Ia, Ib, and IIa with small primary lesion, external irradiation was initially given to pelvis up to $2,000\~3,000\;cGy/2frac{1}{2}\;-3frac{1}{2}$ weeks and then intracavitary insertion was performed using Fletcher-Mini-Declos Applicator with cesium-137 cources and followed by external irradiation of $1,000\~2,000\;cGy/1frac{1}{2}\;-2frac{1}{2}$weeks via AP and PA parallel opposing fields with midline shield to spare of bladder and rectum. However, if the primary lesion is large, external irradiation was given without midline shield. More than stages IIb, the patients were treated by external beam irradiation up to 5,400cGy/30f for 6 weeks via 4-oblique portals and at the dose of 5,040cGy/28f the field was cut 5cm from the top margin for spare of small bowel, and followed by intracavitary irradiation, If there was residual tumor an additional dose of $900\~l,200cGy/5\~7f$ was given to parametrium and/or residual tumor area. Total dose of radiation to A and B-point were as follows; A-point; In early stages, Ia, Ib, IIa; $8,000\~9,000$ B-point $5,000\~6,000 cGy$ A-point; In advanced stages IIb, IIIa, IIIb; $9,000\~10,000$ B-point $60,000\~7,000cGy$ The results were obtained and as fellows; 1 The patients distribution according to FIGO staging system were stage Ia 6, Ib 27, IIa 28, IIb 54, IIIa 12, IIIb 18, and stage IVa 9. 2. Value of CT scan were demonstration of cervix tumor mass, parametrial and pelvic side wall tumor spread, pelvic and inguinal lymph nodes metastases, and hydronephrosis. Three dimensional quantitative demonstration of tumor volume is also important in planning radiation therapy. Another advantage of CT scan was detection of recurrent tumor after radiation or surgery. 3. Local control rate of tumor according to the size was $91.3\%$ for less than 5cm in size and $44.6\%$ in tumor over 5cm (p<0.0068). 4. Thirty out of 50 recurrent sites has locoregional failures and 17 cases has distant metastases. And the para-aortic lymph nodes were the most common site for distant metastases. 5. The most common complication was temporal rectal bleeding which was controlled most by conservative management. However, 4 patients required for endoscopic cauterization. 6. The 5-year survival rates showed; stage la and Ib $95\%,\;stage\;IIa\;81\%\;stage\;lIb\;67\%,\;stage\;IIIa\;37.7\%,\;stage\;IIIb\;23\%$ and 3-year survival rate of stage IVa showed $11.6%$, retrospectively.
