Purpose: The purpose of this study was to analyze clinical outcomes from cervical cancer and stratify patients into risk groups for prognostic factors for early-stage disease. Materials and Methods: We retrospectively reviewed patients with stage IB or IIA cervical cancer treated with adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT) following primary surgery at Samsung Medical Center from 2001 to 2011. Adjuvant RT was added for patients with intermediate-risk factors, and adjuvant CCRT was performed on high-risk patients after surgery. Results: We reviewed 247 patients-149 in the high-risk group and 98 in intermediate-risk group. The median follow-up was 62 months. Loco-regional failure (LRF) alone occurred in 7 patients (2.8%), distant metastasis alone in 37 patients (15.0%) and LRF with DM in 4 patients (1.6%). The 5-year disease-free survival (DFS) and overall survival (OS) rates for both groups were 79.7% and 87.6%, respectively. In the high-risk group, the 5-year DFS and OS probabilities were 72.5% and 81.9%, respectively. Histologic type, pathologic tumor size, and the number of pelvic lymph node (PLN) metastasis were significant prognostic factors for DFS and OS. We suggest a scoring system (0-3) using these prognostic factors to predict poor prognosis in high-risk patients. Using this system, patients with higher scores have higher recurrence and lower survival rates. Conclusion: In the high-risk cervical-cancer group who received primary surgery and adjuvant CCRT, non-squamous type, large tumor size and the number of PLN metastasis were significant prognostic factors, and the number of these factors was associated with survival rates.

Irradiated 88 patients of Maxillary Sinus Carcinoma at Yonsei Cancer Center for 10years between 1971 and 1980 were retrospectively analysed. The majority of patients had very advanced disease(87.5% of $T_3\;and\;T_4$) and 17% of cervical lymph node involvement. 80.6% of all patients were epidermoid type. In 44 cases(50%), irradiation alone was performed. 28 cases(32%) of postoperative radiation after incomplete surgery and the remaining 16 cases(18%) of postoperative radiation after radical surgery were done. The majority of patients except 6 cases had irradiation a dose between 60Gy and 80Gy in 30-40 fractions over 6-8 weeks. The actuarial overall 3 and 5 year survival rate were 362% and 26%, respectively. The actuarial 5 year survival rate for 44 cases of radiation alone group was 14.1%, The actuarial 5 year survival rate for 28 cases of incomplete surgery and postoperative radiation group and 16 cases of radical surgery and postoperative radiation group were 312% and 67.4% respectively. In the actuarial 5 year survival rate according to the stage, stage II, III and IV were 79.5%, 20.9% and 0%. In recent, for the improvement of survival rate of advanced Maxillary Sinus Carcinoma at Yonsei Cancer Center, combined multidisplinary or trimodal treatment modality have been applied and in near time the more excellent results expect to be analyse.

Failed back surgery syndrome (FBSS) is a term that applies to symptoms such as persistent or recurring low back pain, paresthesia, sciatica, or numbness after spine surgery. Electroacupuncture (EA) has been reported to have excellent analgesic effects although there have been no systematic reviews on the effects of EA on FBSS. Therefore, a systematic review and meta-analysis of the effectiveness of EA on FBSS was conducted. Eight databases were searched for studies that used EA for FBSS and 7 randomized controlled trials (RCTs) were included. RCTs of EA as combination therapy for FBSS compared with conventional treatment demonstrated improvement in the level of pain, lumbar functional scale scores, and quality of life. However, meta-analysis showed that reduction in pain was not statistically significant, while evaluation of lumbar function significantly improved, although the quality of evidence in the RCTs was generally low. RCTs comparing EA alone with conventional treatment demonstrated an improved level of pain, lumbar function, and effective rate of treatment. Meta-analysis showed that pain was significantly decreased in the EA alone group compared with the control group, although the quality of evidence was low. To improve the quality of evidence, high-quality RCTs are required in the future.

Objective: The prognostic value of the volume and density of skeletal muscles in the abdominal waist of patients with colon cancer remains unclear. This study aimed to investigate the association between the automated computed tomography (CT)-based volume and density of the muscle in the abdominal waist and survival outcomes in patients with colon cancer. Materials and Methods: We retrospectively evaluated 474 patients with colon cancer who underwent surgery with curative intent between January 2010 and October 2017. Volumetric skeletal muscle index and muscular density were measured at the abdominal waist using artificial intelligence (AI)-based volumetric segmentation of body composition on preoperative pre-contrast CT images. Patients were grouped based on their skeletal muscle index (sarcopenia vs. not) and muscular density (myosteatosis vs. not) values and combinations (normal, sarcopenia alone, myosteatosis alone, and combined sarcopenia and myosteatosis). Postsurgical disease-free survival (DFS) and overall survival (OS) were analyzed using univariable and multivariable analyses, including multivariable Cox proportional hazard regression. Results: Univariable analysis showed that DFS and OS were significantly worse for the sarcopenia group than for the non-sarcopenia group (P = 0.044 and P = 0.003, respectively, by log-rank test) and for the myosteatosis group than for the non-myosteatosis group (P < 0.001 by log-rank test for all). In the multivariable analysis, the myosteatotic muscle type was associated with worse DFS (adjusted hazard ratio [aHR], 1.89 [95% confidence interval, 1.25-2.86]; P = 0.003) and OS (aHR, 1.90 [95% confidence interval, 1.84-3.04]; P = 0.008) than the normal muscle type. The combined muscle type showed worse OS than the normal muscle type (aHR, 1.95 [95% confidence interval, 1.08-3.54]; P = 0.027). Conclusion: Preoperative volumetric sarcopenia and myosteatosis, automatically assessed from pre-contrast CT scans using AI-based software, adversely affect survival outcomes in patients with colon cancer.

목적: 자궁경부암으로 진단을 받고 수술단독 치료만 시행 받은 후 재발암에서 방사선치료를 시행하고 생존율 및 실패양상을 알아보고자 하였다. 대상 및 방법: 1990년 1월부터 1999년 12월까지 계명대학교 동산의료원 방사선종양학과에선 초기(I, IIa) 자궁경부암으로 진단을 받고 수술 후 재발하여 방사선치료를 받은 환자 27명을 대상으로 하였다. 연령분포는 31세에서 70세로 평균 48세이며 수술 당시 병기 1기가 20명, 2기가 7명이었고 23명이 편평상피암이었고 4명은 선암이었다. 수술 후 재발까지의 기간은 2개월에서 90개월로 평균 29개월이었다. 재발부위로는 질 부위가 14명, 골반강이 9명, 복합재발이 4명이었다. 수술은 25명에서 전자궁적출술과 골반내림프절절제술을 시행하였으며 2명은 전자궁적출술만을 시행하였다. 방사선치료는 13명에서는 외부방사선치료만을 받았고 13명에서는 외부방사선치료와 질강내방사선 치료를 받았으며 1명은 질강내방사선치료만을 받았다. 방사선치료 후 추적관찰기간은 6개월에서 128개월로 중앙값 55개월이었다. 결과: 전체 환자의 5년 생존율과 5년 무병생존율은 각각 71.9$\%$, 68.2$\%$이었다. 재발부위에 따른 생존율의 차이가 통계적으로 유의하지는 않았으나 질 부위에만 재발하여 방사선치료를 받은 환자에서 가장 높은 5년 무병생존율을 나타내었다(5년 무병생존율, 질 부위에만 재발한 환자는 85.7$\%$, 질 부위를 제외한 골반부위에 재발한 환자 53.3$\%$, p=0.09). 재발시기에 따른 생존율의 차이는 보이지 않았다. 실패양상으로는 질 부위에만 재발하여 방사선치료를 받은 환자들에서 7$\%$의 국소재발만 있었고 골반강내에 재발하여 방사선치료를 받은 환자들은 국소재발이 주된 실패이었고 골반과 복벽, 복막 등에 같이 재발되었던 환자들은 방사선치료 후 원격전이가 주된 실패이었다. 방사선치료 후 3도 이상의 부작용은 없었다. 결론: 이상으로 볼 때, 초기 자궁경부암에서 수술단독치료 후 재발암에서는 방사선치료는 효과적이고 안전한 치료법이라고 생각되며 특히 수술 후 질 부위에만 재발한 경우에는 외부방사선치료와 질강내방사선치료로 좋은 생존율을 기대할 수 있겠다.

Purpose: Malignant fibrous histiocytoma (MFH) is mainly a soft tissue sarcoma containing fibroblast-like cells and histiocytic cells. MFH in bone accounts for 5% of all malignant bone tumors. MFH of the maxilla is extremely rare and difficult to diagnose due to its scarcity. Treatment mainstay is a complete surgical excision. Radiation therapy is also available when surgery alone is incomplete. Prognosis is not clear but can be devastating. Authors report one case of MFH developed in the maxilla. Methods: A 24-year-old man firstly diagnosed as fibrous dysplasia based on CT findings. Considering facial contour, partial excision was done. But pathology report confirmed malignant fibrous histiocytoma and secondary wide excision was done including zygoma and grossly all affected area. After surgery, radiation therapy was continued. Results: There are no evidence of tumor recurrence after clinical and radiological treatment. Conclusion: MFH of maxilla is very rare and this can leads to misdiagnosis in many clinicians. Surgeon should differentiate this disease from fibrous dysplasia and pathology and MRI are accurate methods for diagnosis of MFH.

The author has studied retrospectively the meniscectomy with temporary silastic implant. The study material used was 4 joints that were possible to be followed up in 9 joints of out of all 145 joints who were diagnosed as internal derangement and have been operated in Yongdong Severance hospital from March 1988 to February 1990. We concluded that the use of temporary silastic implant would prevent the complication which would be arised after meniscectomy alone. And we could obtain the results of the relief of clinical symptoms and maintenance or improvement of joint space when preoperative and postoperative clinical and radiographic findings were compared. The larger number of patients and long term follow-up will be needed for further the investigation.

Background: Epidural opioids are commonly used for postoperative analgesia. However, the side effects of epidural opioids include respiratory depression, sedation, pruritus, nausea, vomiting and urinary retention. Meperidine, due to its intermediate lipid solubility and local anesthetic properties, permits postoperative analgesia. The aim of this study was to compare meperidine alone to meperidine coupled with bupivacaine, and to determine the effects of epidural meperidine without bupivacaine, when used for epidural analgesia following hepatectomy abdominal surgery. Methods: Patients received thoracic epidural analgesia with meperidine alone (3.5 mg/ml in saline) or with additional bupivacaine (0.15%) for 2 days after surgery. Postoperative pain was assessed using a visual analog scale (VAS) pain score 2 days after the operation, with the incidence and dose supplementation also evaluated. Postoperative side effects were assessed using a 3 grade system. Results: No significant difference was found between the two groups in terms of age and weight, or in the pain scores, side effects, incidence and dose supplementation. Conclusions: 3.5 mg/ml epidural meperidine at a dose of 2 ml/hr provides effective postoperative analgesia.
