Gastric cancer is a major cause of cancer-related mortality. At the time of diagnosis, majority of the patients usually have unresectable or metastatic disease. The most common sites of metastases are the liver and the peritoneum, but in the advanced stages, there may be metastases to any region of the body. Bone marrow is an important metastatic site for solid tumors, and the prognosis in such cases is poor. In gastric cancer cases, bone marrow metastasis is usually observed in younger patients and in those with poorly differentiated tumors. Prognosis is worsened owing to the poor histomorphology as well as the occurrence of pancytopenia. The effect of standard chemotherapy is unknown, as survival is limited to a few weeks. This report aimed to evaluate 5 gastric cancer patients with bone marrow metastases to emphasize the importance of this condition.

BACKGROUND/AIMS: Screening for hepatocellular carcinoma (HCC) is a common practice in the endemic countries but its exact role has not been fully investigated. The purpose of this study was to determine whether screening can achieve early diagnosis and survival benefits. METHODS: All HCC patients diagnosed at our hospital (September 1994~April 2000) were enrolled; They were divided into two groups; a surveilled group screened with alpha-fetoprotein (AFP) and ultrasound (US) for longer than 6 months before diagnosis and a non-surveilled group. We compared the tumor size, portal vein thrombosis, and stage at initial diagnosis and survival rate between the two groups. RESULTS: A total of 247 patients were enrolled. 64 were in the surveilled group and 183 were in the non-surveilled group. The tumor size at initial diagnosis in the surveilled group was smaller than in the non-surveilled group (2.6+/-2.0 cm vs. 5.7+/-4.1 cm, p<0.05). The percentages of patients with stage I, II, III, and IV were 42.2%, 20.3%, 14.1%, 23.4% in the surveilled group and 8.7%, 19.7%, 36.6%, 35.0% in the non-surveilled group. A significantly higher proportion in the surveilled group had earlier stage compared with the non-surveilled group (p<0.05). Portal vein thrombosis in the surveilled group was noticed as significantly less than in the non-surveilled group (9.4% vs. 26.8%, p<0.05). Among Child-Pugh A patients, the cumulative survival rate in the surveilled group was significantly higher than in the non-surveilled group (1 year; 91.4% vs. 70.7%, 2 year; 71.5% vs. 59.9%, p<0.05). CONCLUSIONS: Screening with AFP and US is a useful tool for early diagnosis of HCC, especially with improved survival in Child-Pugh A patients.

OBJECTIVETo observe the long-term effects of combined transcatheter arterial chemoembolization (TACE) and radiotherapy for patients with large hepatocellular carcinoma (HCC) and to analyze the prognostic factors.

METHODSA total of 107 patients with large unresectable HCC (the largest diameter of tumor ranged from 5 to 18 cm) were treated with TACE followed by external-beam irradiation. Acute effects and survival rates were observed. The Cox proportional hazards model was used to analyze the prognostic factors.

RESULTSAn objective response was achieved in 48.6% of the cases. The cumulative survival rates at 1, 3, and 5 years were 59.4%, 28.4%, and 15.8%, respectively. The tumor number and irradiation dose were the independent prognostic factors. The cumulative survival rates of the patients with a solitary lesion (75.8%, 43.9%, and 26.8% at 1, 3, and 5 years, respectively) were significantly higher than those with multiple lesions (31.3%, and 5.0% at 1 and 3 years, respectively, P=0.0005). The survival rates of the patients received irradiation above 40 Gy (95.8%, 74.7%, and 37.4% at 1, 3, and 5 years, respectively) were significantly higher than those received 20~40 Gy (60.9%, 20.7%, and 10.3%, respectively) and those received radiation lower than 20 Gy (26.7%, 7.1%, and 7.1%, respectively, P=0.0001).

CONCLUSIONSCombined TACE with radiotherapy is a promising treatment for large unresectable HCC. The number of tumor is the most important clinical prognostic factor. Delivering the highest irradiation dose within the tolerance of the liver is the key to improve the long-term effect.

OBJECTIVETo explore the diagnosis, treatment and long-term outcome of late acute rejection (LAR) following adult orthotropic liver transplantation (OLT).

METHODSA total of 398 consecutive adult patients who underwent OLT in Organ Transplant Center, the First Affiliated Hospital, Sun Yat-sen University between January 2007 and December 2012 were reviewed retrospectively. There were 48 patients (12. 1%) developed to LAR, including 43 male patients and 5 female patients, with an average age of (52 ± 13) years(18 - 70 years). The mean body mass index was (22.1 ± 4. 5) kg/m2 (15. 4 - 30. 4 kg/m2). The indications of the liver transplantation recipients included 16 cases of end-staged liver cirrhosis after hepatitis B or C(33. 3%), 14 cases with severe hepatitis (29. 2%), 9 cases of primary liver cancer(18. 5%), 5 cases of alcoholic liver cirrhosis (10. 4%), 1 case with autoimmune liver disease (2. 1%) , the other 3 cases (6. 3%). They were followed up by outpatient service, telephone and other means. Survival curves were generated with the Kaplan-Meier method and Cox proportional hazards modeling was used for predictors of mortality. Statistically significant variables found by single factor regression analysis were put into the Cox proportional hazards regression model of multivariate analysis.

RESULTSThe time-to-event was 23. 6 months after OLT which were more common in the first year to the third year post-transplant (26/48,52. 4%). Thirty-five cases were assessed as mild, 11 cases were assessed as moderate, and 2 cases were assessed as severe ,based on the Banff schema. After adjustment to the immunosuppressive regimen, the overall recovery rate reached to 81. 3%. The rate of steroid-resistant acute rejection was 11. 8% (4/34). Inadequate immunosuppression and steroid pulsation were two independent risk factors affecting the prognosis of LAR (P = 0. 008, P = 0. 003, respectively).

CONCLUSIONSLAR is an uncommon complication after OLT. Inadequate immunosuppression and steroid pulsation are the major risk factors for prognosis of LAR. Improving patient compliance and strengthening blood concentration surveillance can increase the patient survival.

Because Mongolia has much higher liver disease burden than any other regions of the world, it is necessary to provide information on real-time situation of chronic liver disease in Mongolia. In this article, we reviewed studies performed in Mongolia from 2000 to 2011 on seroprevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) among healthy individuals and patients with chronic liver diseases, and on the practice patterns for the management of liver cirrhosis and hepatocellular carcinoma (HCC). According to previous reports, the seroprevalence of HBV and HCV in general population in Mongolia is very high (11.8% and 15% for HBV and HCV, respectively). Liver cirrhosis is also highly prevalent, and mortality from liver cirrhosis remained high for the past decade (about 30 deaths per 100,000 populations per year). Among patients with cirrhosis, 40% and 39% are positive for HBsAg and anti-HCV, respectively, and 20% are positive for both. The seroprevalence is similar for HCC and more than 90% of HCC patients are positive for either HBV or HCV. The incidence of HCC in Mongolia is currently among the highest in the world. The mortality from HCC is also very high (52.2 deaths per 100,000 persons per year in 2010). Partly due to the lack of established surveillance systems, most cases of HCC are diagnosed at an advanced stage. The mortality from liver cirrhosis and HCC in Mongolia may be reduced by implementation of antiviral therapy program and control of alcohol consumption.

Epithelial ovarian carcinoma is a high mortality neoplasm in gynecologic malignancy. It usually can metastasize to distant organs such as pleura, liver, lung, and lymph nodes. However, the skin metastases are not common and related to very poor prognosis. Here we report a 54-year-old patient with ovarian clear cell carcinoma with skin metastases on the anterior chest at 11 months after initial diagnosis. Although she received palliative chemotherapy, she expired due to disease progression 2 months later after the diagnosis of skin metastases.

BACKGROUND/AIMS: The Korean government has expanded the coverage of the national insurance scheme for four major diseases: cancers, cardiovascular diseases, cerebrovascular diseases, and rare diseases. This policy may have a detrimental effect on the budget of the national health insurance agency. Like taxes, national insurance premiums are levied on the basis of the income or wealth of the insured. METHODS: Using a preference elicitation method, we attempted to estimate how much people are willing to pay for insurance premiums that would expand their coverage for liver cancer treatment. RESULTS: We calculated the marginal willingness to pay (MWTP) through the marginal rate of substitution between the two attributes of the insurance premium and the total annual treatment cost by adopting conditional logit and mixed logit models. CONCLUSIONS: The effects of various other terms that could interact with socioeconomic status were also estimated, such as gender, income level, educational attainment, age, employment status, and marital status. The estimated MWTP values of the monthly insurance premium for liver cancer treatment range from 4,130 KRW to 9,090 KRW.

PURPOSE: Neuroendocrine carcinomas of the stomach account for only about 0.3% of all gastric tumors. The prognosis of this disease is very poor compared with the common type of gastric adenocarcinoma. The purpose of this retrospective study was to review the clinicopathologic features of 18 cases of this unusual gastric tumor and to establish a treatment strategy for this tumor. MATENRIALS AND METHODS: Excluding 2 cases of non-curative resection and 1 case of operative mortality, 18 cases of typical neuroendocrine carcinoma who had curative resection from January 1991 to December 2000 at Asan Medical Center were analyzed; 6841 gastric cancer patient were treated surgically during the same period. RESULTS: The mean age at the time of diagnosis was 58.6 years (range: 35~75 yr). Sixteen patients were male, and two were female. Eleven tumors (61.1%) developed in the lower part of the stomach, three (16.7%) in the middle part, and three (16.7%) in the upper part. One tumor involved the entire stomach. Eight cases (44.4%) were Borrmann type 2, and six case (33.3%) were Borrmann type 3. The mean tumor size was 6.94 cm (range: 0.6~15 cm). Nine cases (50%) showed recurrence of the disease, and eight of them died within 20 months. Of the nine recurred cases, 7 cases (77.8%) showed liver metastasis. The mean disease-free interval was 6.8 months (range: 2.5~11 months) after surgical resection, and the mean survival was 17.9 months (range: 8~40 months) for recurrence cases. One patient with liver metastasis was treated with a liver-wedge resection just after diagnosis and was still alive for 37.5 months postoperatively. There were 9 deaths after the median follow-up period of 40 months (range: 8~72 months). CONCLUSION: Gastric neuroendocrine carcinomas frequently recur at the liver, even in early stage cancer, and have a poor prognosis. We experienced a case of successful control of hepatic metastasis by surgical resection and a case of a small cell carcinoma which was successfully controlled with systemic chemotherapy.

OBJECTIVE: To retrospectively evaluate the safety and efficacy of percutaneous radiofrequency ablation (RFA) in patients with metachronous hepatic metastases arising from pancreatic adenocarcinoma who had previously received curative surgery.MATERIALS AND METHODS: Between 2002 and 2017, percutaneous RFA was performed on 94 metachronous hepatic metastases (median diameter, 1.5 cm) arising from pancreatic cancer in 60 patients (mean age, 60.5 years). Patients were included if they had fewer than five metastases, a maximum tumor diameter of ≤ 5 cm, and disease confined to the liver or stable extrahepatic disease. For comparisons during the same period, we included 66 patients who received chemotherapy only and met the same eligibility criteria described.RESULTS: Technical success was achieved in all hepatic metastasis without any procedure-related mortality. During follow-up, local tumor progression of treated lesions was observed in 38.3% of the tumors. Overall median survival and 3-year survival rates were 12 months and 0%, respectively from initial RFA, and 14.7 months and 2.1%, respectively from the first diagnosis of liver metastasis. Multivariate analysis showed that a large tumor diameter of > 1.5 cm, a late TNM stage (≥ IIB) before curative surgery, a time from surgery to recurrence of < 1 year, and the presence of extrahepatic metastasis, were all prognostic of reduced overall survival after RFA. Median overall (12 months vs. 9.1 months, p = 0.094) and progression-free survival (5 months vs. 3.3 months, p = 0.068) were higher in the RFA group than in the chemotherapy group with borderline statistical difference.CONCLUSION: RFA is safe and may offer successful local tumor control in patients with metachronous hepatic metastases arising from pancreatic adenocarcinoma. Patients with a small diameter tumor, early TNM stage before curative surgery, late hepatic recurrence, and liver-only metastasis benefit most from RFA treatment. RFA provided better survival outcomes than chemotherapy for this specific group with borderline statistical difference.

BACKGROUND AND AIMS: Hepatitis C virus (HCV)-associated cirrhosis is an increasingly frequent indication for liver transplantation (LT). However, HCV recurrence is universal and this immediately occurs following LT, which endangers both the graft and patient survival. We investigated the frequency of posttransplant recurrence of HCV infection and the patient-graft survival, and we analyzed the responses to ribavirin and interferon therapy in the patients with recurrent HCV infection after living donor liver transplantation (LDLT). METHODS: We retrospectively reviewed the clinical outcomes of 39 HCV-associated cirrhosis patients who underwent LDLT at Asan Medical Center between August 1992 and June 2006. In this study, the diagnosis of recurrent HCV was made on the basis of increased transaminases and serum HCV RNA levels greater than 10 million IU/mL because protocol liver biopsy was not performed. RESULTS: HCV recurrence was seen in 26 of the 39 LDLT patients (66.7%). 86.7% of recurrence occurred within the first postoperative year. Antiviral treatment was used for all patients with recurrence of HCV. None of the 10 patients receiving ribavirin alone and 9 of 16 patients who received combination therapy with pegylated interferon alpha-2a plus ribavirin became HCV RNA negative and they remained persistently negative during the median follow-up of 24.9 months. Our data indicates that there is no significant factor influencing HCV recurrence except for the recipient's age. The 2-year patient survival for the HCV patients with HCC and those patients without HCC were 81.2% and 81.3%, respectively (P=0.85) and the 2-year graft survival rates were 81.2% and 68.2%, respectively (P=0.29). No patient died from HCV recurrence during the follow-up period. CONCLUSIONS: Combination therapy with ribavirin and interferon appears to improve the outcome of recurrent HCV infected patients after LDLT.
