Pyogenic liver abscess in patients with malignant disease is a fatal state and is easily diagnosed. We presented a rare case of sudden fatal septicemia following anticancer treatment for recurred gastric cancer due to multiple liver abscesses which could not be diagnosed. A 72-year-old male with recurred gastric cancer received anticancer agents. He had a history of distal gastrectomy with right hepatic lobectomy for hepatic metastasis. He received anticancer treatment in the outpatient's service center periodically, and his performance status was preserved with nothing in particular. After administrating docetaxel, he suddenly developed septicemia and multiple organ failure and died 5 days after strong medical supports. Pathological autopsy revealed that multiple minute abscesses of the liver which could not be detected macroscopically were the causes of fatal septicemia. The etiology, therapies and prognosis of rare entity are being discussed.

Objective: To explore the most appropriate treatment for patients with hepatocellular cancer (HCC) >10 cm by using the Barcelona Clinic Liver Cancer (BCLC) classification. Materials and Methods: A total of 124 HCC patients undergoing surgery were selected. Disease-free survival (DFS), overall survival (OS) and prognostic factors were respectively assessed. Results: This study showed that the cumulative 1-, 3-, 5-year survival rates were 79.7%, 59.8% and 41.6% in BCLC-A patients, 76.2%, 9.5% and 0% in BCLC-B patients and 44.9%, 0% and 0% in BCLC-C patients, respectively. The 1-, 3-, 5-year DFS rates were 49%, 24.5% and 9.1% in BCLC-A patients, 7.5%, 0% and 0% in BCLC-B patients, respectively. No BCLC-C patients survived 1 year after surgery. Multivariate analysis indicated that hepatitis B surface antigen (HBsAg), vascular invasion, intra-hepatic metastasis, curative resection, tumor rupture and pathologic differentiation were independent prognostic factors. Conclusions: Surgery is effective and safe for patients with HCC >10 cm with sufficient hepatic reserve.

In patients with neuroendocrine tumors with liver metastases (NETLMs), complete resection of both the primary and liver metastases is a potentially curative option. When complete resection is not possible, debulking of the tumour burden has been proposed to prolong survival. The objective of this systematic review was to evaluate the effect of curative surgery (R0-R1) and debulking surgery (R2) on overall survival (OS) in NETLMs. For the subgroup of R2 resections, outcomes were compared by the degree of hepatic debulking (≥ 90% or ≥ 70%). A systematic review of the literature was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines using PubMed, Medline, CINAHL, Cochrane, and Embase databases. Hazard ratios (HRs) were estimated for each study and pooled using a random-effects inverse-variance meta-analysis model. Of 538 articles retrieved, 11 studies (1,729 patients) reported comparisons between curative and debulking surgeries. After pooling these studies, OS was found to be significantly shorter in debulking resections, with an HR of 3.49 (95% confidence interval, 2.70-4.51; p < 0.001). Five studies (654 patients) compared outcomes between ≥ 90% and ≥ 70% hepatic debulking approaches. Whilst these studies reported a tendency for OS and progression-free survival to be shorter in those with a lower degree of debulking, they did not report sufficient data for this to be assessed in a formal meta-analysis. In patients with NETLM, OS following surgical resection is the best to achieve R0-R1 resection. There is also evidence for a progressive reduction in survival benefit with lesser debulking of tumour load.

Objectives : The present study was carried out investigate the anti-cancer effect of Salvia miltiorrhiza, Carydalis turtschaminovii and Reynoutria elliptica herbal acupuncture on solid tumor of rats induced by injection of RK3E-ras cells. Methods : RK3E-ras cells were injected on the right lumbar region of rats. After 1 weeks, the experimental rats were divided into four groups : Control group, Salvia miltiorrhiza herbal acupuncture group(SM), Carydalis turtschaminovii herbal acupuncture group(CT), Reynoutria elliptica herbal acupuncture group(RE). And we investigated the weight and size of tumor tissue, gross anatomy, histological and PCNA immunohistochemical study, hepatic and renal metastasis for tumor of each group. Results : 1. In the weight of tumor tissue assessment, SM and CT's weight of tumor tissue was decreased. 2. In the size of tumor tissue assessment, SM was smaller than any other group. 3. In the histological observation, SM's formation of tunica fibrosa that surround the tumor cell was obvious and vasculature that developes circumference of tumor cell was not observed, and density of tumor cell was very low. 4. In the PCNA immunohistochemical study, Control group, SM, RE showed strong immune response in the central site of tumor tissue. 5. In observation of liver and kidney tissue, we were not able to observe tumor cell in the SM. Conclusions : Consequently, SM and CT showed a inhibition of growth and metastasis.

We found that the main bacterial metabolite M1 is an active component of orally administered protopanxadiol-type ginsenosides, and that the anti-metastatic effect by oral administration of ginsenosides may be primarily mediated through the inhibition of tumor invasion, migration and growth of tumor cells by their metabolite M1. Pharmacokinetic study after oral administration of ginsenoside Rb1 revealed that M1 was detected in serum for 24 h by HPLC analysis but Rb1 was not detected. M1, with anti-metastatic property, inhibited the proliferation of murine and human tumor cells in a time- and concentration-dependent manner in vitro, and also induced apoptotic cell death (the ladder fragmentation of the extracted DNA). The induction of apoptosis by M1 involved the up-regulation of the cyclin-dependent kinase(CDK) inhibitor $p27^{Kip1}$ as well as the down-regulation of a proto-oncogene product c-Myc and cyclin D1 in a time-dependent manner. Thus, M1 might cause the cell-cycle arrest (G1 phase arrest) in honor cells through the up/down-regulation of these cell-growth related molecules, and consequently induce apoptosis. The nucleosomal distribution of fluorescence-labeled M1 suggests that the modification of these molecules is induced by transcriptional regulation. Tumor-induced angiogenesis (neovascularization) is one of the most important events concerning tumor growth and metastasis. Neovascularization toward and into tumor is a crucial step for the delivery of nutrition and oxygen to tumors, and also functions as the metastatic pathway to distant organs. M1 inhibited the tube-like formation of hepatic sinusoidal endothelial (HSE) cells induced by the conditioned medium of colon 26-L5 cells in a concentration-dependent manner. However, M1 at the concentrations used in this study did not affect the growth of HSE cells in vitro.

Metastases to the liver presents a common clinical problem in the management of patients with cole-rectal cancer, and are responsible for a high degree of morbidity and mortality associated with this malignancy. Unfortunately, attempts at preventing the development of liver metastases in "high risk" patients has so far been unsuccessful. Ongoing studies of adjuvant chemotherapy have not yet illustrated a significant increase in survival in patients receiving such therapy. The purpose of the study is to investigate the value of adjuvant radiotherapy given in the form of colloidal chromic phosphate P-32 suspension administered via portal vein after radical resection of the primary cancer, in preventing the growth of occult metastases in the liver. Twenty one patients (10 patients of treated group with 11 controls) were followed 18 months after operation. There was no significant change in the CBC and liver functions after administration of P-32 labeled colloidal chromic phosphate. The number of patients who showed local metastases at 18 months were 2 in the treated group and 3 in the control group. While liver metastases occurred in one patient at 6 months and in three at 12 months in the control group, there was no development of liver metastases by 12 months in the treated group. At 18 month follow-up CT scan one patient in the treated group showed a single nodule in the liver. In conclusion liver metastasis rate was lower in the patients who received colloidal P-32 chromic phosphate via portal vein after radical resection of the primary cole-rectal cancer.

Liver cancer is a common tumor and currently the second leading cause of cancer-related mortality globally. Liver cancer is highly related to inflammation as more than 90% of liver cancer arises in the context of hepatic inflammation, such as hepatitis B virus and hepatitis C virus infection. Despite significant improvements in the therapeutic modalities for liver cancer, patient prognosis is not satisfactory due to the limited efficacy of current drug therapies in anti-metastatic activity. Therefore, developing new effective anti-cancer agents with anti-metastatic activity is important for the treatment of liver cancer. In this study, SP-8356, a verbenone derivative with anti-inflammatory activity, was investigated for its effect on the growth and migration of liver cancer cells. Our findings demonstrated that SP-8356 inhibits the proliferation of liver cancer cells by inducing apoptosis and suppressing the mobility and invasion ability of liver cancer cells. Functional studies revealed that SP-8356 inhibits the mitogen-activated protein kinase and nuclear factor-kappa B signaling pathways, which are related to cell proliferation and metastasis, resulting in the downregulation of metastasis-related genes. Moreover, using an orthotopic liver cancer model, tumor growth was significantly decreased following treatment with SP-8356. Thus, this study suggests that SP-8356 may be a potential agent for the treatment of liver cancer with multimodal regulation.

Necropsy was performed on a total of twenty three either white leghorn or ogol chickens which were more than 150 weeks of age. Among twenty three chickens examined, fifteen chickens were laying and the rest eight chickens were non-laying. On necropsy, neoplastic mass in the five chickens among non-laying chickens was found. These neoplastic masses were present mostly in the ovaries and one case in the liver and characterized by multifocal to coalescing 1 to 5 mm tan firm nodular formation. On histopathology, ovarian adenocarcinoma with widespread abdominal seeding and hepatic metastasis was diagnosed in the three chickens. Oviductal leiomyoma was also found in two chickens that had a focal well-demarcated nodules in the oviduct. Taken together, the number with ovarian adenocarcinoma among non-laying chickens over 150 week old was 37.5%. As most animal species do rarely develop ovarian tumors, the high rate of spontaneous ovarian adenocarcinoma in non-laying hen suggest that the hen is a proper model for human ovarian cancer study.

Colorectal cancer is extremely rare in children. Unlike adult colorectal cancer, the overall prognosis of colorectal cancer in children is poor. Delayed diagnosis, advanced stages of the disease at presentation, and mucinous type of histology are the major determinants of poor outcome in childhood. A 13-year-old boy with abdominal pain visited our hospital. Physical examination andabdominal ultrasonography identified acute appendicitis with perforation. He underwent appendectomy and then the pathologic findings revealed mucinous adenocarcinoma. The cancer was located at the transverse colon and had metastases on peritoneal wall at $2^{nd}$ laparotomy. Extended right hemicolectomy was performed. He underwent palliative chemotherapy. After 4 months later, hepatic metastasis and aggravated peritoneal seedings developed. He died of renal failure and pneumonia 13 months after operation. We need to have a high index of suspicion for the possibility of a malignant colorectal tumor in any childhood case with nonspecific signs and symptoms.

An example of lymphoblastic lymphosarcoma was diagnosed in a 7-year-old male brown bear (Ursus arctos) that died after having a 7-month history of depression, anorexia and watery diarrhea. Grossly the mesenteric lymph nodes were enlarged to approximately 4 to 6 times their normal size and histologically diagnosed as lymphoblastic lymphosarcoma. The small intestinal mucosa was corrugated and had severe mural thickening due to infiltrated neoplastic cells. Hepatic metastasis was also noted. the mother of this bear which died at the age of 20 also had similar gross changes on necropsy, but histological examination was not performed at that time and therefore the exact type of neoplasm remained to be determined. Since the daughter also died of neoplasm, genetic factor could be suspected in this family. This is the first reported case of lymphosarcoma in Ursidae in Korea. As an incidental finding, endogenous lipid pneumonia was noted in the lung.
