A 79-year-old man was diagnosed with gastrointestinal stromal tumor (GIST) of the gastric cardia. We performed proximal subtotal gastrectomy and started imatinib therapy as adjuvant treatment after surgery. Whole body skin rash with urticaria was onset on 10 days after imatinib treatment, and the patient decided to stop imatinib because of side effect. After 3 months, PET CT revealed GIST was recurred at spleen and abdominal lymph nodes, abdominal wall. The patient was then restarted on imatinib therapy. On follow-up imaging studies, the tumor almost disappeared, but both pleural effusion and pericardial effusion were found. In this paper, we describe a case of clinical course and side effects in recurred GIST after adjuvant imatinib mesylate treatment.

배경 및 방법 : 근치적 절제술 후 재발한 비소세포폐암 환자의 임상적 특징과 재발 양상을 알아보고자 1994년부터 삼성서울병원에서 근치척 절제술을 시행한 1,2기 비소세포폐암환자 256명중 1년 이상 추적 관찰이 가능하였던 234명을 대상으로 후향적 조사를 하여 다음과 같은 결과를 얻었다. 결 과 : 1) 전체 환자의 남녀 비율은 3.1:1이었고 연령의 중앙값은 63세로서 평균 추척 기간은 732일(365일~1,695일)이었다. 234명중 재발한 환자는 62명으로 26.5%였고 재발 기간은 수술후 평균 358.8일이었다. 2) 재발군과 비재발군의 임상양상을 비교하면 재발군의 연령이 많았으며($63.2{\pm}8.8$세 vs. $60.3{\pm}9.8$세, p=0.043), 재발율은 2기 환자가 1기 환자보다 높았다(6.0% vs. 21.2%, p<0.001). 원발암의 크기는 비재발군($3.74{\pm}1.75\;cm$)이 재발군($5.45{\pm}3.22\;cm$) 보다 작았고(p<0.001), 2cm 미만에서 재발이 발견된 경우는 없었다. 3) 원격 재발군과 국소성 재발군과의 분석에서 빈도는 원격 재발(66.1%)이 국소성 재발(33.9%)보다 많았고, 원격 재발은 여자가 남자보다 많았다(11/12명, 91.7% vs. 30/50 명, 60.0%. p=0.037). 선암이 편평세포상피암보다 원격 재발율이 높았고(20/25명, 80.0% vs. 15/29 명, 51.7%. p=0.030). 뇌전이 발생율이 선암(50.0%)에서 편평세포상피암(13.3%)보다 높았다(p=0.024). 4) 평균 생존 기간은 $1437.6{\pm}40.3$일이었고, 병기가 높을수록 생존기간이 길었다(log rank p<0.001). 결 론 : 1,2기 비소세포폐암의 근치적 절제술 후 재발은 26.5%에서 일어났고 종양의 크기 및 병기가 재발에 관련된 인자였다. 원발암의 크기가 2cm미만일 경우 재발된 경우가 없어 예후가 좋을 것으로 기대되며, 재발암 중에서는 여성과 선암에서 원격 재발율이 높았고 특히 뇌전이는 선암에서 많이 발생하여 수술 전 뇌영상 검사에 대한 전향적 연구가 필요할 것으로 생각된다.

Purpose: The prognosis for early gastric cancer (EGC) is favorable, and the 10-year disease-specific survival rate is reported to be around $90\%$. The absolute number of recurred EGC is too small to assess the risk factors, so recruitment of a large number of cases for statistical analysis is very difficult. We carried out this study to analyze the incidence and the patterns of recurrence of EGC and to identify the clinicopathological risk factors for recurrence of EGC. Materials and Methods: The authors retrospectively investigated the follow-up records of 1418 patients who underwent a curative resection for EGC from Jan. 1984 to Dec. 1999 at the Korea Cancer Center Hospital and analyzed them with special reference to cancer recurrence. Results: In this retrospective study of 1418 cases, 43 patients died of a recurrence of gastric cancer, and 105 patients died of unrelated causes. The five-year and the ten-year overall survival rates were $89.6\%$ and $81.7\%$, respectively, while the five-year and the ten-year diseasespecific survival rates were $96.5\%$ and $94.3\%$, respectively. The recurrence patterns of the 45 recurred EGC were hematogenous metastasis (19 cases), lymph node (L/N) metastasis (8 cases), locoregional recurrence (2 cases), peritoneal seeding (3 cases), and combined form (13 cases). The mean time interval to recurrence was 38.6 months, and the number of delayed recurred cases after 5 years was 10 ($22.2\%$). Of the clinicopathologic factors, depth of invasion, L/N metastasis, macroscopic type, lymphatic invasion, and vessel invasion, were significant risk factors in the univariate analysis. However, in the multivariate analysis, only L/N metastasis was an independent prognostic factor. Conclusion: Based on the results of this study, L/N metastasis is an independent prognostic factor. Thus, in patients with node-positive disease, adjuvant therapy might be considered, and long-term close follow-up might facilitate early detection and treatment of recurrent disease due to delayed recurrence.

허혈성 뇌졸중의 재발에 관여된다고 생각되는 주요 위험인자들을 파악하기 위하여 영남대학교 의과대학 부속병원 신경과에 내원한 환자들중 재발된군과 비재발된군을 선정하여 통상적으로 알려진 뇌졸중 위험인자들을 조사하여 그 중 뇌졸중 재발에 영향을 끼치는 요인을 분석 검토하였다. 재발군의 성별은 77명중 남자가 55명, 여자가 22명이었으며, 비재발군은 124명중 남자가 84명, 여자가 40명으로 성별차이를 분석해보면 의미있는 위험인자로 작용하지 못했다. 재발군의 연령은 29세에서 85세까지 평균 62.1세였고 비재발군은 27세에서 90세로 평균연령은 60.7세로 두군 모두 다 60대에서 가장 높은 발병율을 보였고 이 역시 통계적 유의성이 없었다. 당뇨병, 심근경색, 심방세통, 일과성 뇌 허혈증등과 같은 위험 요인이 있더라도 재발에는 영향을 미치지 못한것으로 나타났고 또한 뇌졸중의 병형이나 병변부위도 재발에 미치는 영향은 별로 없는 것으로 조사되었다. 그러나, 고혈압의 병력이나 입원기간중 높은 혈압을 보인 경우는 두군간에 유의성이 있는 차이를 보였다(P<0.05). 이상의 결과로 처음 뇌졸중이 발병하여 입원중 측정한 혈압이 160mmHg/95mmHg 이상으로 높았거나 고혈압의 병력이 있는 경우에는, 그렇지 않은 환자에 비해 향후 2년 내에 허혈성 뇌졸중이 재발할 가능성이 높으므로 적절한 치료로서 예방에 도움을 얻는 것이 필요할 것으로 생각되며, 이외의 위험인자들에 대해서도 지속적 연구가 있어야 할 것으로 사료된다.

Purpose: Even with excellent surgical outcome, recurrence of early gastric cancer (EGC) after a curative resection is not declining because the incidence of EGC is increasing. The aim of this study was to propose an appropriate treatment strategy by assessing the risk factors for recurrence of curatively resected early gastric cancer. Materials and Methods: Of 3662 patients who had undergone gastric resections for gastric cancer from 1987 to 1996, the cases of 1050 curatively resected EGC patients were reviewed retrospectively. Among those 1050 patients, 50 patients ($4.8\%$) were diagnosed as having recurrent cancer, which was confirmed by clinico-radiological examination or re-operation. The risk factors that determined the recurrence patterns were investigated by using univariate and multivariate analyses. Results: The mean time to recurrence was 30.9 months, and hematogenous recurrence was the most frequent type ($32.0\%$). Among the 50 recurred patients, peritoneal recurrence showed the shortest mean time to recurrence ($18.5\pm17.7$months). Between the recurred and the non-recurred patients, there was no statistically significant difference with respect to age, sex, operation type, tumor size, tumor location, gross appearance, or histological differentiation. However, depth of invasion (submucosal invasion) and nodal involvement were significantly different (P<0.001) between the two groups. Using logistic regression analyses, nodal involvement was the only significant risk factor for recurrence in early gastric cancer (P<0.001). The median survival after the recurrence had been diagnosed was 4 months. Conclusion: Although the prognosis for EGC patients is excellent and recurrence of EGC after a curative resection is rare, the time to recurrence and the patterns of recurrence in EGC patients were diverse and unpredictable, and the result after recurrence is dismal. Considering the impact of lymph node metastasis on recurrence of EGC, a systematic lymphadenectomy, rather than limited surgery, should be performed if lymph node involvement is confirmed pre- or intraoperatively. Also if the postoperative pathologic findings reveal lymph node involvement, adjuvant chemotherapy is recommended.

Ossifying fibroma is a rare benign tumor of the maxilla and the mandible. And its nosology and diagnosis have had many problems. It occurs more common in young adult, especially in female, and there is a predilection for the mandible. The lesion is generally asymptomatic and recurrence is rare after conservative excision. Among ossifying fibroma, juvenile active ossifying fibroma grows rapidly, produces many symptoms, and frequently recurs after conservative excision. Authers experienced a case of juvenile active ossifying fibroma which recurred after two times of conservative surgery, and report is with review of the literatures.

Background and Objective : Laryngeal Papillomatosis (LP) is the most common benign neoplasm of the larynx, but it tend to recur and it makes eradicating difficult. Meticulous $CO_2$ laser excision has been the most effective treatment to date. This article analyzes the clinical feature and therapeutic results of 42 LP patients who were undergone $CO_2$ laser excision. Methods : Forty two patients with recurrent LP were treated with $CO_2$ laser. And their medical records were reviewed retrospectively. Demographics, chief complaints at onset, initial distribution of papillomas, number of operations performed on each patient, and current results were evaluated. Results : Male in their twenties and forties are dominant in number in patient number. Most common site was anterior one thirds (69%) of glottis area (86%). LP recurred in 17 cases (40%), and in 4 cases, the lesion extended over the original margin. Patients were undergone surgery $1.62{\pm}0.87$ times, $2.53{\pm}0.72$ in recurred cases. Mean relapsing time was 6 momths (from 1momth to 8years). Ant. laryngeal web occurred in 2 cases (4.8%) and 1 case was combined with squamous cell carcinoma. Conclusion : Meticulously performed $CO_2$ laser excision can achieve significant voice and airway improvement and clinical cures. The $CO_2$ laser through microdirect laryngoscopy allows more precise and bloodless removal of papillomas.

CyberKnife is a stereotactic radiosurgery system which could be used to treat many tumors and lesions. It provides the surgeon unparalleled flexibility in targeting using a compact light linear accelerator mounted on a robotic arm. Advanced image guidance technology tracks patient and target position during treatment, ensuring accuracy without the use of an invasive head frame. CyberKnife with Dynamic Tracking Software is cleared to provide radiosurgery for lesions anywhere in the body when radiation treatment is indicated. It has often been used to radiosurgically treat otherwise untreatable tumors and malformations. Moreover, this instrument treats tumors at body sites, most of which are unreachable by other stereotactic systems. Compared with conventional radiotherapy, it is fundamentally different that using non-invasive, frameless, no excessive radiation exposure to normal tissue. In oral malignant neoplasm, surgical excision and radiation therapy should be tried first, additionally chemotherapy could be considered. However, after failure of conventional therapies, patients had poor systemic condition and surgical limitation. So, CyberKnife could be a suitable therapy. A 49 years man was referred in recurred mandibular cancer treated by radiotherapy. The tumor was considered inoperable, because of extensive invasion and was not expected to good response to conventional therapies. We experienced a case of CyberKnife after 4 cycle chemotherapies, so we report it with review of literature.
