Purpose: The effects of hepatic resection on patients with metastatic tumors from gastric adenocarcinomas are unclear. Therefore, we analyzed early clinical outcomes in patients who underwent surgical resection for hepatic metastases from gastric adenocarcinomas. Materials and Methods: From January 2003 to December 2010, 1,508 patients with primary gastric cancers underwent curative gastric resections at the Korea Cancer Center Hospital. Of these patients, 12 with liver-only metastases underwent curative hepatic resection. Their clinical data were analyzed retrospectively. Results: The median follow-up period was 12.5 months (range, 1~85 months); no operative mortalities or major complications were observed. Three patients underwent synchronous resections, and 9 underwent metachronous resections. In the latter group, the median interval between gastrectomy and hepatectomy for hepatic metastasis was 10.5 months (range, 5~47 months). The overall 1- and 5-year survival rates of these 12 patients were 65% and 39%, respectively, with a median overall survival of 31.0 months; 2 patients survived for >5 years. Conclusions: Hepatic resection can be a feasible procedure for treating hepatic metastases from gastric adenocarcinomas. Although this study was small and involved only selected cases, the outcomes of the hepatic resections were comparable and long-term (>5 years) survivors were identified. Surgical resection of the liver can be considered a feasible option in managing hepatic metastases from gastric adenocarcinomas.

대장암이나 타 장기 암의 간전이 경우 간 절제는 비교적 좋은 결과를 가지는 치료 방법으로 보고되고 있으나, 위암의 간전이에 대한 치료로 절제 수술의 역할과 생존율에 대한 효과는 연구가 많지 않은 실정이다. 위암의 수술 전 진단 때나 수술 후 추적 검사 중 진단된 간전이의 경우 많은 예에서 다발성 전이, 좌, 우엽에 전이, 간외 전이, 복막 파종이나 다발성 림프절 전이 양상으로 절제 수술의 적응이 되지 못하는 악성 경로를 가지는 경우가 많다. 그러나 몇몇 보고에서는 수술 적응 대상 환자가 적으나 간절제 치료로 좋은 결과를 보고하는 경우도 있어 제한된 간전이 환자에 대한 맞춤 치료의 영역은 있다고 하였다. 위암의 간전이 절제 예에 대한 보고를 종합하여 보면 간전이 병소가 진단되는 시기가 예후에 중요하여 동시성으로 전이가 진단된 경우가 나쁘며, 절제연이 10 mm 이상 유지 될 때 좋은 결과를 보고하였다. 반면 전이 병소의 개수는 생존율 검사에서 통계학적 의미는 없는 것으로 보고 되었다. 또한 충분한 절제연을 확보하면서 해부학적 구역 절제 이상의 수술이 시행된 경우와 이시성 간전이가 좋은 생존율을 보이는 것으로 보고되었다. 또한 간 절제 수술 후 가장 많은 재발 병소는 역시 간으로, 재발 시 대부분 2년 내 사망을 초래하여 절제 후 보조항암화학요법 치료도 중요하다.

Background: The optimal surgical strategy for the treatment of synchronous resectable gastric cancer liver metastases remains controversial. The aims of this study were to analyze the outcome and overall survival of patients presenting with gastric cancer and liver metastases treated by simultaneous resection. Materials and Methods: Between January 1990 and June 2009, 35 patients diagnosed with synchronous hepatic metastases from gastric carcinoma received simultaneous resection of both primary gastric cancer and synchronous hepatic metastases. The clinicopathologic features and the surgical results of the 35 patients were retrospectively analyzed. Results: The 5-year overall survival rate after surgery was 14.3%. Five patients survived for more than 5 years after surgery. No mortality has occurred within 30 days after resection, although two patients (5.7%) developed complications during the peri-operative course. Univariate analysis revealed that patients with the presence of lymphovascular invasion of the primary tumor, bilateral liver metastasis and multiple liver metastases suffered poor survival. Lymphovascular invasion by the primary lesion and multiple liver metastases were significant prognostic factors that influenced survival in the multivariate analysis (p=0.02, p=0.001, respectively). Conclusions: The presence of lymphovascular invasion of the primary tumor and multiple liver metastases are significant prognostic determinants of survival. Gastric cancer patients without lymphovascular invasion and with a solitary synchronous liver metastasis may be good candidates for hepatic resection. Simultaneous resection of both primary gastric cancer and synchronous hepatic metastases may effectively prolong survival in strictly selected patients.

Background: The liver is one of the most common metastatic sites of breast cancer, hepatic metastases developing in 6%-25% of patients with breast cancer and being associated with a poor prognosis. The aim of this study was to analyze the survival and clinical characteristics of patients with hepatic metastases from breast cancer of different molecular subtypes and to investigate the prognostic and predictive factors that effect clinical outcome. Methods: We retrospectively studied the charts of 104 patients with breast cancer hepatic metastases diagnosed at Sun Yat-sen University Cancer Center from December 1990 to June 2009. Subtypes were defined as luminal A, luminal B, human epidermal growth factor receptor 2 (HER2) enriched, triple-negative (TN). Prognostic factor correlations with clinical features and treatment approaches were assessed at the diagnosis of hepatic metastases. Results: The median survival time was 16.0 months, and the one-, two- three-, four-, five-year survival rates were 63.5%, 31.7%, 15.6%, 10.8%, and 5.4%, respectively. Median survival periods after hepatic metastases were 19.3 months (luminal A), 13.3 months (luminal B), 18.9 months (HER2-enriched), and 16.1 months (TN, P=0.11). In multivariate analysis, a 2 year-interval from initial diagnosis to hepatic metastasis, treatment with endocrine therapy, and surgery were independent prognostic factors. Endocrine therapy could improve the survival of luminal subtypes (P=0.004) and was a favorable prognostic factor (median survival 23.4 months vs. 13.8 months, respectively, P=0.011). Luminal A group of patients treated with endocrine therapy did significantly better than the Luminal A group of patients treated without endocrine therapy (median survival of 48.9 vs. 13.8 months, P=0.003). Conclusions: Breast cancer subtypes were not associated with survival after hepatic metastases. Endocrine therapy was a significantly favorable treatment for patients with luminal subtype.

Metastases to the liver can be found in various malignancies, most commonly originating from the colon, rectum, pancreas, stomach, esophagus, breast, lung, and melanoma. Surgical resection of liver metastasis is generally considered to be the definitive therapy fore cure. However, many patients are unable to undergo surgical resection due to medical comorbidities or multifocal extent of malignant disease affecting the liver. Among patients not eligible for surgery, other therapies exist for treatment in order to down stage the disease for surgical resection or for palliation. Radioembolization of hepatic metastases has shown to improve outcomes among patients with variety of malignancies including more common malignancies such as colorectal cancer. Yttrium-90 (Y-90) radioembolization has been successfully used in the management of hepatic metastases. A small series of metastatic sarcoma to the liver treated with radioembolization showed a promising response. We report a case of metastatic gastric leiomyosarcoma to the liver treated with Y-90 glass microspheres therapy using the radiation segmentectomy approach, previously described for hepatocellular carcinoma.

목적: 동시성 및 이시성 간전이 위암환자들을 대상으로 임상병리학적 특성 및 예후의 차이에 대하여 알아보고 치료 방법에 따른 예후에 대하여 알아보고자 하였다. 대상 및 방법: 1992년 6월부터 2006년 12월까지 한양대학교병원 외과예서 치료받은 위암 환자 중 간전이가 발견된 67명의 환자를 대상으로 임상병리학적 특징 및 치료 방법에 대하여 후향적 분석을 시행하였다. 결과: 두 군의 임상병리학적 특성에 대한 비교에서 림프관 침윤 여부(P=0.041)와 혈관 침윤 여부(P=0.036)가 동시성군에서 유의하게 많았다. 전체 간전이 위암환자의 1년 생존율과 중앙생존기간은 38.9%, 9.2개월이며 동시성 간전이군에서는 30.9%. 9.2개월이었고 이시성 간전이군에서는 44.5%, 9.7개월로 두 군 사이에 통계학적으로 유의한 차이는 없었다(P=0.436). 치료 방법을 수술 혹은 영상의학적 중재술 등의 국소적 치료와 전신적 항암화학치료를 병행한 경우, 전신적 항암화학치료만 받은 경우, 치료 받지 않은 경우 등 세 가지로 나누었을 때 동시성 간전이군과 이시성 간전이군 사이에 치료 방법의 차이는 없었으며 두 군 모두에서 국소적 치료를 전신적 치료와 병행하였을 경우 생존율이 높았다(P<0.001). 결론: 간전이 위암에 있어서 간전이 병소의 발생 시점에 따른 예후의 차이는 없을 것으로 생각한다. 또한 간전이 발견 시점과 관계 없이 적응 예가 되는 경우 수술적 치료나 영상의학적 중재술 등의 적극적인 치료가 환자의 예후 향상에 기여할 수 있겠다.

Background: The purpose of this retrospectively study was to examine the effectiveness and tolerability of a radiotherapy technique for the palliation of symptomatic liver metastases. Materials and Methods: Twentyseven patients with liver metastases were enrolled and received targeted whole liver irradiation consisting of mean 1, 8 Gy in five to twelve fractions to a total mean dose 17Gy. Symptoms at baseline were hepatic pain (26 patients), lost of weight (6), lack of appetite (2), and night sweats (1). Seventeen patients (63%) had failed previous treatment with chemotherapy and/or high-dose steroids. Results: Individual symptom response rates were 100% at 4 weeks. Partial or complete global symptomatic responses were noted in 11 patients (40%) after 2 months. After 3 months, 8 patients (28%) reported loss of pain. The treatment was well tolerated with one patient (3%) experiencing grade 3 toxicity (one vomiting and one diarrhoea). Overall the median survival time was 4.9 months (range 1 - 14 months). One year survival was 39%. Conclusions: This is simple and well-tolerated treatment but to achieve good palliation effects we should carefully selected patients whose conventional treatment does not bring good analgesic control.

Alveolar echinococcosis (AE) is considered as a fatal zoonosis caused by the larvae of Echinococcus multilocularis. The lungs and brain are the most common metastatic organs. We report a human case of hepatic alveolar echinococcosis accompanied by lung and brain metastasis. In particular, the patient had a history of tuberculosis and the lung lesions were easily misdiagnosed as lung abscesses. The lesions of liver and lung underwent radical resection and confirmed as alveolar echinococcosis by pathological examination. The patient had no surgical complications after operation and was discharged after symptomatic treatment. Unfortunately, the patient later developed multiple intracerebral AE metastases. We required the patient to take albendazole orally for life and follow up.

Hepatocellular carcinoma is the most common primary tumor in the liver. FDG PET has been applied for staging and treatment planning of hepatocellular carcinoma. It could reflect tumor prognosis because glucose metabolism assessed by FDG PET is known to have correlations with the differentiation and aggressiveness of the tumor. Although the ability of FDG PET to detect well-differentiated or low grade tumors and intra-hepatic lesions is not good, it is expected to playa major role in pre-surgical assessments for liver transplantation because it is useful in detecting extra-hepatic lesions and unexpected distant metastases with a better diagnostic performance than other conventional imaging modalities. Additionally, FDG PET has an advantage to screen other cancers through whole body scanning. As a new tracer for PET, Acetate demonstrates higher sensitivity and specificity to FDG in evaluating hepatocellular carcinoma. It thus seems that simultaneous use of Acetate PET with FDG PET could be helpful in diagnosis, especially detecting extra-hepatic metastases.

Background: The purpose of this study was to analyze our series of liver resections for metastatic colorectal carcinoma (mCRC) to determine prognostic factors affecting survival and to evaluate the potential roles of neoadjuvant or adjuvant chemotherapy. Materials and Methods: Ninety-nine patients who underwent metastasectomy for liver metastases due to colorectal cancer at the Department of Medical Oncology, 9 Eylul University Hospital between 1996 and 2010 were evaluated in this study. The patients were followed through July 2013. Demographic, perioperative, laboratory, radiological and chemotherapy as well as survival data were obtained by retrospective chart review. Results: In 47 (47.5%) patients, liver metastases were unresectable at initial evaluation; the remaining 52 (52.5%) patients exhibited resectable liver metastases. Simultaneous hepatic resection was applied to 52 (35.4%) patients with synchronous metastasis, whereas 5 (64.5%) patients underwent hepatic resection after neoadjuvant chemotherapy. Forty-two patients with metachronous metastasis underwent hepatic resection following neoadjuvant chemotherapy. R0 resection was obtained in 79 (79.8%) patients. A second hepatectomy was performed in 22 (23.2%) patients. Adjuvant chemotherapy was given to 85 (85.9%) patients after metastasectomy. The median disease-free and overall survivals after initial metastasectomy were 12 and 37 months, respectively, the 1-year, 3-year and 5-year disease-free survival (DFS) and overall survival (OS) rates being 46.5%, 24.3% and 17.9%and 92.3%, 59.0% and 39.0%, respectively. On multivariate analysis, the primary tumor site, tumor differentiation, resection margin and DFS were independent factors predicting better overall survival. Conclusions: In selected cases, hepatic metastasectomy for mCRC to the liver can result in long-term survival. Neoadjuvant chemotherapy did not exert a positive effect on DFS or OS. Adjuvant chemotherapy also did not appear to impact DFS and OS.
