Infantile hemangioendothelioma(IHE) of the liver is the most common vascular tumor in infants before the age of 6 months. It is a histologically benign tumor with potentially life-threatening complications. The clinical manifestations are variable, ranging from asymptomatic forms to intractable high-output heart failure. In addition, abdominal mass, intraperitoneal hemorrhage due to rupture of mass, respiratory distress, hematologic abnormalities and jaundice can occur. Diagnostic work-up is through doppler ultrasound sonography, computed tomography scan, magnetic resonance imaging and angiography. Treatment consists of medical treatment, interventional therapy, surgical resection and liver transplantation. We experienced symptomatic IHE in a premature neonate who presented with high output heart failure and respiratory distress. Initial medical treatment and steroid therapy failed to improve his condition. Coil embolization of left hepatic artery resulted in improvement of respiratory symptoms. However, a left lobectomy was performed because the mass size was not decreased with development of collateral vessels. The infant was well, after a successful discharge from the hospital.

Objective: This study aimed to review herbal remedy-based RCTs on cancer patients in order to produce helpful information for clinical study of herbal medicine in the future. Methods: We collected all RCTs using herbal remedies on cancer patients from Pubmed and Cochrane databases until November 1st, 2009. Elementary information such as nation where performed, clinical question, design, randomization, double-blinding and allocation concealment were analyzed. Results: 153 RCTs were finally selected. 119 RCTs were conduced in China while only 2 were done in Korea. The most frequent targeted cancer was lung cancer as 29 RCTs. The main clinical questions included improvement of quality of life, elongation of survival rate and regression of tumor being 83, 62 and 55 respectively. 112 RCTs used herbal remedies with western therapy. Adequate methods for randomization and allocation concealment were found in 37% and 10% of trials respectively. Conclusions: We found that herbal remedies are used on cancer patients in aspects of both caring for the human body and tumor treatment itself. The study might provide us useful data for cancer-related clinical study using herbal remedies in the future.

Purpose: To evaluate the outcomes of stereotactic body radiation therapy (SBRT) for patients with liver oligo-recurrence and oligo-progression from various primary tumors. Materials and Methods: Between 2002 and 2013, 72 patients with liver oligo-recurrence (oligo-metastasis with a controlled primary tumor) and oligo-progression (contradictory progression of a few sites of disease despite an overall tumor burden response to therapy) underwent SBRT. Of these, 9 and 8 patients with uncontrollable distant metastases and patients immediate loss to follow-up, respectively, were excluded. The total planning target volume was used to select the SBRT dose (median, 48 Gy; range, 30 to 60 Gy, 3-4 fractions). Toxicity was evaluated using the Common Toxicity Criteria for Adverse Events v4.0. Results: We evaluated 55 patients (77 lesions) treated with SBRT for liver metastases. All patients had controlled primary lesions, and 28 patients had stable lesions at another site (oligo-progression). The most common primary site was the colon (36 patients), followed by the stomach (6 patients) and other sites (13 patients). The 2-year local control and progression-free survival rates were 68% and 22%, respectively. The 2- and 5-year overall survival rates were 56% and 20%, respectively. The most common adverse events were grade 1-2 fatigue, nausea, and vomiting; no grade ${\geq}3$ toxicities were observed. Univariate analysis revealed that oligo-progression associated with poor survival. Conclusion: SBRT for liver oligo-recurrence and oligo-progression appears safe, with similar local control rates. For liver oligo-progression, criteria are needed to select patients in whom improved overall survival can be expected through SBRT.

Liver tumors in children are rare, relatively complex, and encompass a broad spectrum of disease processes. This study reviews our experience of liver tumors during the last 10 years. Medical records of 36 cases of liver tumors in children, treated at Samsung Medical Centers, from October 1994 to December 2005, were reviewed in this study. We analyzed disease characters and survival rates as a whole and by specific disease. The median age was 3.6 years. Male and female ratio was 1:1. The most common symptom was the palpable mass in 15 cases. Others were abdominal distension in 9 cases, jaundice in 2, vomiting in 2, weight loss in 2, and pubic hair growth in 1. CT or US and liver biopsy were performed for diagnosis. There were 28 malignant tumors: malignant rhabdoid tumor (1 case), hepatocellular carcinoma (3 cases), hemangioendothelioma type II (3 cases), angiosarcoma (1 case), and hepatoblastoma (20 cases). Eight tumors were benign; hepatic adenoma (1 case), focal nodular hyperplasia (2 cases), hemangioendothelioma type I (2 cases), mesenchymal hamartoma (3 cases). In this study the clinical characteristics were not different from the other reports. Liver transplantation was performed in 3 cases-1 with hepatoblastoma and 2 with hepatocelleular carcinoma. Accurate and early diagnosis, and individualized multimodality therapeutic approaches might be important for better outcome.

Hepatic hemangioma is the most frequently occurring benign tumor of the liver. Hepatic hemangioma rupture is a rare phenomenon, which can lead to life-threatening conditions. Here, we report a case of hepatic hemangioma rupture caused by blunt trauma. Explorative laparotomy was performed due to unstable vital signs and abdominal massive hemoperitoneum revealed on computed tomography. We detected arterial bleeding from a hepatic hemangioma and performed primary suture of the liver and postoperative angiographic embolization.

Primary liver carcinomas have classified classified into hepatocellular carcinoma, cholangiocarcinoma, and combined hepatocellular-cholangiocarcinoma (CHC). CHC is a tumor containing unequivocal, intimately mixed elements of both hepatocellular carcinoma and cholangiocarcinoma. It forms a small but significant proportion of primary liver carcinomas. The origin and pathogenesis of CHC have not been well established. According to the 2010 WHO classification, CHCs are categorized into 2 groups: the classical type and a subtype with stem cell features. This review describes recent progress in pathology and classification of CHC.

Respiratory motion in the thorax and abdomen is an important limiting factor in high-precision radiation therapy. The lung tumor and tumor(pancreas, stomach) in abdomen therefore are internal motion due to breathing. We will perform to measurement of dose distributions for these moving tumors. In preliminary study, we investigated displacement of moving tumor such as liver, lung tumor in abdomen with previously reported papers. With reference data, internal movements of tumor are displayed with phantom and moving control device(MCD), which appear three dimension (3-D) motion such as x, y and z axis. These devices are used to access dose delivered in tumor with and without internal motion. The MCD and phantom were used to evaluate a delivered dose under similar condition, although there are not same internal tumor motion. In future, we will obtain the exact evaluation of dose if improved in programed software of moving control device and measure precise internal motion using image modality such as fluoroscopy, simulator in based on this study.

Objective: To compare expression level of serum tumor associated materials (TAM) with several conventional serum tumor biomarkers, eg., carcinoembryonic antigen (CEA), carbohydrate antigen19-9 (CA19-9), carbohydrate antigen 15-3 (CA15-3), alpha-fetoprotein(AFP), in selected solid tumors. Methods: Patients diagnosed histologically or cytologically with liver, breast, esophageal, gastric, colorectal or pancreatic cancers were enrolled into this study. After diagnosis, the level of TAM was determined by chemical colorimetry, and levels of conventional tumor markers was measured by chemiluminescence methods. Results: A total of 560 patients were enrolled into this study. No statistically significant difference was detected in TAM and the above mentioned tumor biomarkers in terms of their positivity and negativity ( P>0. 05). Conclusions: Detection of TAM in liver, breast, esophageal, gastric, colorectal, and pancreatic cancer patients demonstrates a good accordance with CEA, CA199, CA153, and AFP, thus suggesting that further study is warranted to verify whether TAM could be a surrogate for these conventional biomarkers.
