  • Background: Intrahepatic cholangiocarcinoma (IHCCA) is an aggressive tumor for which surgical resection is a mainstay of treatment. However, recurrence after resection is common associated with a poor prognosis. Studies regarding recurrence of mass-forming IHCCA are rare; therefore, we investigated the pattern with our dataset. Methods: We retrospectively reviewed the medical and pathological records of 50 mass-forming IHCCA patients who underwent hepatic resection between January 2004 and December 2009 in order to determine the patterns of recurrence and prognosis. All demographic and operative parameters were analyzed for their effects on recurrence-free survival. Results: The median recurrence-free survival time was 188 days (95%CI: 149-299). The respective 1-, 2-, and 3-year recurrence-free survival rates were 16.2% (95%CI: 6.6-29.4), 5.4% (95%CI: 1.0-15.8) and 2.7% (95%CI: 0.2-12.0). There was an equal distribution of recurrence at solitary and multiple sites. Univariate analysis revealed no factors related to recurrence-free survival.Conclusion: The overall survival and recurrence-free survival after surgery for mass-forming IHCCA were found to be very poor. Almost all recurrences were detected within 2 years after surgery. Adjuvant chemotherapy after surgery may add benefit in the affected patients.

  • Purpose: To identify prognostic factors for disease progression and survival of patients with extracranial oligometastatic breast cancer (EOMBC), and to investigate the role of radiation therapy (RT) for metastatic lesions. Materials and Methods: We retrospectively reviewed the medical records of 50 patients who had been diagnosed with EOMBC following standard treatment for primary breast cancer initially, and received RT for metastatic lesions, with or without other systemic therapy between January 2004 and December 2008. EOMBC was defined as breast cancer with five or less metastases involving any organs except the brain. All patients had bone metastasis (BM) and seven patients had pulmonary, hepatic, or lymph node metastasis. Median RT dose applied to metastatic lesions was 30 Gy (range, 20 to 60 Gy). Results: The 5-year tumor local control (LC) and 3-year distant progression-free survival (DPFS) rate were 66.1% and 36.8%, respectively. High RT dose (${\geq}50Gy_{10}$) was significantly associated with improved LC. The 5-year overall survival (OS) rate was 49%. Positive hormone receptor status, pathologic nodal stage of primary cancer, solitary BM, and whole-lesion RT (WLRT), defined as RT whose field encompassed entire extent of disease, were associated with better survival. On analysis for subgroup of solitary BM, high RT dose was significantly associated with improved LC and DPFS, shorter metastasis-to-RT interval (${\leq}1month$) with improved DPFS, and WLRT with improved DPFS and OS, respectively. Conclusion: High-dose RT in solitary BM status and WLRT have the potential to improve the progression-free survival and OS of patients with EOMBC.

  • This study was conducted to compare the effects of n-6 linoleic acid and n-3 linolenic acid on lipid peroxidation and the activities of enzymes defending against oxidation, which are involved in the tumor promotion, and histolOgical changes of hepatocarcinogen treated rat liver. In this study, weanling male Sprague-Dawley rats were fed one of three diets, containing 15% (w/w) of beef fat (BF), com oil (CO) or perilla oil (PO), for 11 weeks. During the 3rd week, experimental groups were injected with 2-AAF (50 mg/kg of BW) intraperitoneally 3 times. Findings show that the com oil diet group has greater liver MDA content than the beef fat and perilla oil diet groups. Also, it is observed that the perilla oil diet group has lower MDA content than beef fat and com oil diet groups, even though perilla oil is more desaturated than beef fat and com oil. In terms of activity, mixed-function oxidase activity is not Significantly affected by the different dietary fats and 2-AAF treatment. GSH-peroxidase, GSH-reductase and GSH-Stransferase activities are significantly higher in the CO+AAF group than those of the other groups. GST and GSH-Px are activated by 2-AAF treatment in the com oil diet group only. The hepatocytes of the BF+AAF group were the most severely degenerated, the second was the CO+AAF group and the least was the PO+AAF group. It was also found that dietary com oil increased lipid peroxidation and activated defense enzymes against oxidation in liver, but dietary perilla oil did not, or supressed defense enzymes. Therefore it is concluded that dietary n-3 linolenic acid in perilla oil inhibits lipid peroxidation and carcinoenesis in rat liver following 2-AAF treatment.

  • Pulmonary epithelioid hemangioendothelioma (PEH) is a rare, low-to-intermediate malignant tumor of endothelial origin. Computed tomography (CT) findings of PEH demonstrate multiple small bilateral nodules; however, to the best of our knowledge, there were no reports on PEH coexisting with other malignancies. Here, we reported on a case involving PEH in a patient with colon cancer and breast cancer which was misconceived as pulmonary meta- stasis. A 63-year-old woman who suffered from constipation for 2 weeks visited our hospital. Colonoscopy showed a large mass with obstruction on hepatic flexure. The histological diagnosis was adenocarcinoma of the ascending colon. Multiple nodules in both lungs and breast were observed on a chest CT scan. A core biopsy of a breast nodule was performed and a diagnosis of invasive ductal carcinoma of the left breast was made. Pulmonary nodules observed on the chest CT scan was considered as pulmonary metastasis from colon or breast cancer. Laparoscopic right hemicolectomy was performed. At the same time, wedge resection of the lung was performed and pathological diagnosis was PEH. Radiologic features of PEH were difficult to distinguish from lung metastasis. Therefore the author reported a rare case involving PEH in a patient with primary malignancy of colon and breast.

  • The study was performed to investigate the histological findings and the appearances of positive cells by immunohistochemical methods using proliferating cell nuclear antigen (PCNA) antibody and apoptotic kit in diethylnitrosamine (DEN) -induced rat liver cancer model. Forty four male rats (Sprague Dawley), initially 5 to 6 weeks of age and 120 to 150gm in body weight were continuously were given with water containing 0.01% DEN for 13 weeks and 3~6 rats per week were randomly sacrified at intervals of a week from 8 weeks to 17 weeks. The interlobular connective tissues in the rat livers were proliferated at early 8 weeks. The vaccuolated or fatty degenerated liver cells were focally distributed and then widely distributed with the passage of weeks and the liver cells with large vacuoles tended to be crowded in focal areas, and the liver cells in some lobules were transformed into small or eosinophilic polyhedral large cells. The hepatocellular carcinoma and the cholangiocarcinoma were simultaneously developed in same liver and tended to be markedly developed after 12 weeks but the development of carcinoma in some livers at same week were less or more advanced as 3~5 week intervals. The regions with more number of positive cells by PCNA antibody or apoptotic kits in livers were ranked as following order ; small hepatocellular carcinoma regions, cholangiocarcinoma regions, trabecular or acinar type carcinoma regions, and large liver cell regions. The numbers of the positive cells by PCNA antibody were more numerous than those by apoptotic kit. So these findings suggested that the volumes and weights of the livers were increasing by more many proliferating of carcinoma cells on the above ordered regions.

  • The study was designated to investigate the gross findings following treatment with diethylnitrosamine (DEN) in rats. Forty four male rats (Sprague Dawley), initially 5 to 6 weeks of age and 120 to 150gm in body weight were continuously given water containing 0.01% DEN for 13 weeks and 3~6 rats per week were randomly sacrified at intervals of a week from 8 weeks to 17 weeks. The numbers of rats died until 17 weeks were 11 rats and first death occurred at 10 weeks. Body, liver and spleen weights were weighed and the relative weight levels of the liver and spleen per body weights were increased from 4.4% and 0.5% at control groups to 15.1% and 1.1% at 17 weeks. The numbers of RBC were not varied but PCV were decreased from 44.5% in control group to 27.5% in 16 weeks. A few of greyish-white foci or nodules of tumors were developed or not on the surfaces of the livers at 8 weeks but were developed on all livers after 9 weeks. The diameter of the largest tumor from all rat livers was 35.8 mm at 12 weeks. The numbers of developed tumors per a rat liver were appeared to be about 20 in 13 weeks and about 50~60 in 17 weeks. The diameter of some larger tumors were found to be 3~9mm in 13 weeks and 7~15mm in 17 weeks and more number of tumors were developed in the visceral surfaces than in the diaphragmatic surfaces of the livers. The parenchymae of livers were fragility.

  • Scutellaria barbata D. Don (S. barbata), a traditional Chinese medicine, is used to treat cancers, inflammation, and urinary diseases. This study aimed to determine any protective effects of S. barbata crude extract (CE-SB) against rat liver tumorigenesis induced by diethylnitrosamine (DENA). Liver malfunction indices in serum were measured by biochemical examination. Hematoxylin and eosin staining was performed to examine liver pathology. Contents of malondialdehyde (MDA) and superoxide dismutase (SOD) were measured in liver homogenates to evaluate oxidative stress. The levels of liver malfunction indices in the CE-SB groups, especially in the CE-SB high dose group, were lower than that of the model group (P<0.05). The results from histological examination indicated that the number of liver nodules in the CE-SB groups decreased compared with the model group (P<0.05). Content of MDA determined in liver was significantly decreased, and level of SOD elevated by CE-SB. CE-SB can inhibit experimental liver tumorigenesis and relieve hepatic injury in rats.

  • Background/Aims: Dong-Moo Lee Jae-Ma(1837-1900) confirmed the sasangchaejil theory based on the sasang-medicine. This theory has been the main-stem of oriental medicine during 100 years in Korea. But rarely anyone has tried to prove this theory systemicaly. So we have a trial to clarify any relationship between the sasangchaejil and the laboratory and clinical results of mass screening tests. Methods: We evaluated the laboratory values of 280 people who had taken many clinical and laboratory tests. The laboratory examinations were complete blood count, liver and kidney function test, ultrasonogram of the abdomen and breasts, gastrofiberscope, many tumor markers body mass index, blood pressure, glucose, and electrocardiogram, etc. Results: 1) Among the 280 subjects, 187/66.8% were sowumin, 58/20.7% were taewumin and 35/12.5% were soyangin. 2) Those who reacted positive to HBsAb were 22 subjects(62.8%) in soyangin, 57.2% in sowumin and 55.1% in raewumin. But there were no significant correlations. 3) 45 subjects(72.4%) in taewumin had obesity, fatty liver and hyperlipidemia.(P<0.05) 4) 20.6% in taewumin had abnormal LFT suggesting hepatic disease. It was statistically sigificant.(P<0.05) 5) An anemic state was present in women of soyangin and sowumin mostly. Since an iron deficiency anemia is common in women, there were no significant corelations among sasangchaejil. Also urinary tract infectons were common in women. 6) 6 subjects in taewumin(10.3%) had cardiac problems, while only one case(2.8%) occured in soyangin and 7 cases(3.7%) in sowumin. Taewumin was significantly high.(P<0.05) 7) In the case of gastric disease, there was no distinguishable difference among sasangchaejil.(taewumin 37.9%, soyangin 31.4% and sowumin 35.2% rrespectively) 8) There was no significant difference beteen subjects with different blood types using sasangchaejil. Conclusions: There were some significant relationship between sasangchaejil and diseases prevalent to them by the theory of sasang-medicine. But Lee didn't considered the differences of gender, the change of body status according to the development of culture, and circumstances of their lives. Also he didn't consider the existence of infectious agents. Now more systemic study with larger populations are requied.
