Objective : The treatment of giant cell tumor (GCT) is mainly performed surgically. However, GCT in spine seems difficult to treat because of the limited surgical accessibility and proximity. In this report, we analyzed the outcome of GCT treatment in spine. Methods : Between 2000 and 2012, 19 patients received treatment for GCT in spine. Median age at their first diagnosis was 31 years, 10 patients were male, and 9 female. Fourteen tumors were located in the sacrum, 1 in cervical, 1 in thoracic and 3 in lumbar spine. As primary treatment, gross total removal (GTR) was done in 6 patients, and subtotal removal (STR) in 13 patients. Radiation therapy (RT) as an adjuvant therapy was performed in 2 cases in GTR group and 10 cases in STR group. Results : During the follow-up, 7 patients had local recurrence (36.8%). The average period until recurrence after primary treatment was 14 months. No recurrence was detected in GTR group. Recurrence was noted in 7 out of 13 patients who underwent STR. These differences were statistically significant (p=0.024). A median of recurrence free period (RFP) was 84 months. Also average RFP of the RT group was 112 months, and non-RT group was 65 months. These differences were statistically significant (p=0.041). Conclusion : Treatment of choice for GCT in spine is a complete removal of tumor without neurological deficits. In case of incomplete removal, radiation therapy may be a useful adjuvant treatment modality.

Objectives : The purpose of this case study is to demonstrate the effectiveness of Traditional Korean Medicine as an adjunctive management for breast cancer treatment. Methods : A 56 year-old female patient diagnosed with stage IA(pT1cN0M0) of breast cancer was admitted our hospital. The patient had surgical resection followed by radiation therapy, and conducted adjuvant therapy with aromatase inhibitor. The patient's chief complaints were dry cough, thirst and fatigue, all of which were caused by radiation therapy. Traditional Korean herbal medicine was prescribed for symptom management. The patient's subjective symptoms such as cough, thirst and fatigue were evaluated by NRS. Results : Fatigue was significantly improved within a week. The severity of dry cough and thirst also was decreased after a few courses of herbal medicine treatment. Conclusion : This case study suggests that Tradition Korean Medicine would be beneficial for the patients who are suffering from adverse effects of the standard treatment of cancer.

Breast cancer is the most common in women worldwide, with some 5-10% of all cases due to inherited mutations of BRCA1 and BRCA2 genes. Obesity, hormone therapy and use of alcohol are possible causes and over-expression of leptin in adipose tissue may also play a role. Normally surgery, radiation therapy and chemotherapy allow a good prognosis where screening measures are in place. New hope in treatment measures include adjuvant therapy, neoadjuvant therapy, and introduction of mono-clonal antibodies and enzyme inhibitors.

목적: 근치적 절제술을 받고 AJCC 병기 2기(T3또는 N1)로 진단된 췌장암 환자들 중 수술 후 방사선치료를 받은 이들을 대상으로 국소 제어율 및 생존율을 분석하고자 한다. 대상 및 방법: 1996년 1월부터 2005년 12월까지 수술 후 보조적 요법으로 방사선치료 단독 내지는 동시 항암화학 방사선치료를 받은 28명의 환자들의 기록을 후향적으로 분석하였다. 모든 환자들에게서 병리 소견상 췌장 주변 조직으로의 침윤이 있거나 체장 주변 또는 후복강 내 대동맥 주변 임파절 전이가 확인되었다. 방사선치료는 수술 전 영상학적인 자료에서 침범된 종양의 위치 및 수술 변연 부위를 중심으로 $40{\sim}57.6$ Gy (중앙값 50 Gy)를 조사하였으며 병리 소견상 주변 임파절 전이가 확인된 경우엔 제 3 요추부위까지의 대동맥 주변 임파절 부위도 조사야에 포함시켰다. 동시 항암화학요법은 10명의 환자들에게서 병용되었다. 결 과: 최초의 실패 양상이 국소 재발이었던 환자는 13명(46%)였으며 이들 중에서 원격 전이가 같이 동반된 환자는 5명이었다. 호발 부위는 복강축(4명)과 대동맥 주변 임파절 부위였다. 또한 원격 전이가 최초의 실패 양상으로 나타난 환자는 국소재발이 동반된 환자들을 포함하여 72명이었다. 원격전이가 가장 흔히 나타난 곳은 간(10명)이었으며 복강전이, 폐전이 순이었다 임파절 전이가 있는 환자들은 없는 환자에 비해 원격 전이의 가능성이 높았다. (57.1%). 수술 변연 부위에 종양이 남아있는 환자들은 없는 환자들보다 국소 재발의 가능성이 높았다(57.1%). 전체 환자들의 무병 생존기간의 중앙값은 6개월이었으며 1년 및 2년 무병생존율은 각각 27.4%와8.2%였다. 전체 생존기간의 중앙값은 11개월이었고 2년, 3년 생존율은 31.5%, 15.8%였다. 결 론: 2기 췌장암 환자들은 국소 재발 및 원격 전이의 가능성이 높은 고위험군으로 국소 제어율 및 전체 생존율의 향상을 위해서 수술 후 효과적인 방사선치료의 적극적인 시행 및 이후의 보조적인 전신 항암화학요법을 권고하여 시행하는 것이 바람직하다.

서론 : 완치 목적의 절제술을 시행 후 국소재발된 직장암환자에 대한 방사선치료 결과 및 생존율에 미치는 예후인자에 대해 평가하고자 하였다. 대상 및 방법 1982년 7월부터 1996년 5월까지 인제대부속 백병원과 한양대부속병원 방사선종양학과에서 국소재발된 직장암으로 방사선치료를 시행받은 총 28명의 환자를 대상으로 치료결과에 대한 후향적 분석을 시행하였다. 남녀비는 14:14이었고, 연령분포는 31세에서 72세 사이로 나타났다(평균 연령:54.5세). 일차 수술 후 국소 재발까지의 기간은 4개월에서 46개월로 관찰되었다(중앙값:10개월). 방사선치료는 총 27Gy에서 64.8Gy(median; 51.2Gy)가 조사되었다. 50.OGy 이하로 조사된 환자는 모두 11례로 나타났으며, 17례에서 50.OGy 이상이 조사되었다. 결과 : 증상완화는 전체 환자 중 17례(60.7%)에서 관찰되었고, 출혈 및 통증을 호소한 환자의 경우 각기 100%와 40%%에서 증상완화가 관찰되었다. 증상완화정도의 방사선 조사량에 따른 차이는 관찰되지 않았다. 방사선치료 시작 일부터 전체 환자의 중앙생존기간은 16.7개월이고, 2년 및 5년 생존율은 20.1%, 4.1%로 나타났다. 생존율에 대한 예후 인자를 분석해 보았을 때, 단일변량분석에서 일차 수술 후 국소재발까지의 기간이 유일한 예후인자로 나타났다. 그 외 연령, 성별, 임상수행능력정도, 재발부위, 초기병기, 초기 수술방법, 원격전이여부, 방사선조사량 등은 유의한 인자로 관찰되지 않았다. 즉 일차 수술 후 국소재발까지의 기간이 1년 이상인 경우에서 1년 이하에 비해 의미있게 높은 생존율이 관찰되었다(2년 및 5년 생존율:42.0%, 8.4% vs 0.0%)(P<0.05). 다변량분석에서도 생존율과 연관된 예후 인자로는 일차 수술후 국소재발까지의 기간만이 의미있게 관찰되었다. 결론 : 본 연구에서는 방사선치료가 국소재발된 직장암환자에서 병변으로 인한 증상을 완화시키는 데 효과적이며, 일부의 환자에서는 장기간의 생존이 가능함을 알 수 있었다. 그러나, 전체적으로 2년 및 5년 생존율이 저조하게 나타났고, 일차 수술 후 국소재발까지의 기간이 생존율에 영향을 미치는 것으로 관찰되어, 향후 국소 재발된 직장암 환자에서 생존율의 향상을 위한 효과적인 치료법에 대한 연구가 필요하겠고, 더불어 초기 치료 후 국소재발방지를 위해 부가치료에 대한 적극적인 연구가 우선되어야겠다.

We experenced 18 patients with surgically treated thymoma from January 1986 to December 1993. There were 13 male and 5 female ranged from 23 to 69 years of age. Among them Myasthenia gravis was present in 8 patients (44%) The predominant cell type was lymphocytic(11 patients), followed by epithelial (3) and mixed (4), and had no value in predicting prognosis. Treatment consisted of complete resection in 15 patients, partial resection in 2 patients and 1 patient was performed biopsy. Only, and then adjuvant radiation therapy was done in 7 patients and 3 patients needed adjuvant chemotherapy. Invasion of the adjacent tissue in thymoma was the most improtant prognostic value. There were 6 non-invasive tumors and 12 invasive tumors. Two patients with invasive thymomas resulted in death and one of 6 patients with non-invasive thymomas died during follow up ranged from 25 day to 60 months. The causes of death were myasthenic crisis in 1 patient, C. N. S. problem in 1 patient and pulmonary & mediastinal metastasis in 1 patient.

A case report of a patient who developed radiation-induced sarcoma in the left chest wall is presented. The patient had partial mastectomy and adjuvant radiation therapy (total dose, 5,220 cGy) and chemotherapy. Five years later, she visited with rapidly growing mass with central ulceration in the irradiated chest wall. The mass was diagnosed as malignant fibrous histiocytoma. The chest wall mass resected en bloc ($23{\times}18cm$) including five consecutive ribs. After the defected thoracic cage was reinforced using a polytetrafluoroethylene patch, omental flap and split thickness skin graft was done for soft tissue coverage. We applied negative pressure wound closer system for effective suction of omeantal exudate. The wound healed without complications. The patient suffered no perioperative pulmonary complications. Pulmonary function tests showed no significant changes. Each of Gore-Tex, omental flap, negative pressure wound therapy and skin graft is widely used method. However, If these methods are used in combination, we can reconstruct the large defect of chest wall including multiple ribs without any repiratory function problems.

Background: Radiotherapy is an important treatment of choice for breast cancer patients after breast-conserving surgery, and we compare the feasibility of using dual arc volumetric modulated arc therapy (VMAT2), single arc volumetric modulated arc therapy (VMAT1) and Multi-beam Intensity Modulated Radiotherapy (M-IMRT) on patients after breast-conserving surgery. Materials and Methods: Thirty patients with breast cancer (half right-sided and half left-sided) treated by conservative lumpectomy and requiring whole breast radiotherapy with tumor bed boost were planned with three different radiotherapy techniques: 1) VMAT1; 2) VMAT2; 3) M-IMRT. The distributions for the planning target volume (PTV) and organs at risk (OARs) were compared. Dosimetries for all the techniques were compared. Results: All three techniques satisfied the dose constraint well. VMAT2 showed no obvious difference in the homogeneity index (HI) and conformity index (CI) of the PTV with respect to M-IMRT and VMAT1. VMAT2 clearly improved the treatment efficiency and can also decrease the mean dose and V5Gy of the contralateral lung. The mean dose and maximum dose of the spinal cord and contralateral breast were lower for VMAT2 than the other two techniques. The very low dose distribution (V1Gy) of the contralateral breast also showed great reduction in VMAT2 compared with the other two techniques. For the ipsilateral lung of right-sided breast cancer, the mean dose was decreased significantly in VMAT2 compared with VMAT1 and M-IMRT. The V20Gy and V30Gy of the ipsilateral lung of the left-sided breast cancer for VMAT2 showed obvious reduction compared with the other two techniques. The heart statistics of VMAT2 also decreased considerably compared to VMAT1 and M-IMRT. Conclusions: Compared to the other two techniques, the dual arc volumetric modulated arc therapy technique reduced radiation dose exposure to the organs at risk and maintained a reasonable target dose distribution.

Purpose: To evaluate the impact of postoperative radiotherapy (PORT) on patterns of failure and survivals in uterine carcinosarcoma patients treated with radical surgery. Materials and Methods: Between October 1998 and August 2010, 19 patients with stage I-III uterine carcinosarcoma received curative hysterectomy and bilateral salpingo-oophorectomy with or without PORT at Seoul National University Hospital. Their hospital medical records were retrospectively reviewed. PORT and non-PORT groups included 11 and 8 patients, respectively. They were followed for a mean of 22.7 months (range, 7.8 to 126.6 months). Results: At 5 years, the overall survival rates were 51.9% for entire, 61.4% for PORT, and 41.7% for non-PORT groups, respectively. There was no statistical difference between PORT and non-PORT groups with regard to overall survival (p = 0.682). Seven out of 19 (36.8%) patients showed treatment failures, which all happened within 12 months. Although the predominant failures were distant metastasis in PORT group and loco-regional recurrence in non-PORT group, there was no statistically significant difference in locoregional recurrence-free survival (LRRFS) (p = 0.362) or distant metastasis-free survival (DMFS) (p = 0.548). Lymph node metastasis was found to be a significant prognostic factor in predicting poor LRRFS (p = 0.013) and DMFS (p = 0.021), while the International Federation Gynecology and Obstetrics (FIGO) stage (p = 0.043) was associated with LRRFS. Conclusion: Considering that adjuvant radiotherapy after surgical resection was effective to decrease loco-regional recurrence and most treatment failures were distant metastasis, multimodal therapy including surgery, radiotherapy, and chemotherapy might be an optimal treatment for uterine carcinosarcoma patients.
