| 1 | Clinical features and prognosis of patients with extrahepatic metastases from hepatocellular carcinoma显示文摘AIM: To assess the clinical features and prognosis of 151 patients with extrahepatic metastases from primary hepatocellular carcinoma (HCC), and describe the treatment strategy for such patients. METHODS: After the diagnosis of HCC, all 995 consecutive HCC patients were followed up at regular intervals and 151 (15.2%) patients were found to have extrahepatic metastases at the initial diagnosis of primary HCC or developed such tumors during the follow-up period. We assessed their clinical features, prognosis, and treatment strategies. RESULTS: The most frequent site of extrahepatic metastases was the lungs (47%), followed by lymph nodes (45%), bones (37%), and adrenal glands (12%). The cumulative survival rates after the initial diagnosis of extrahepatic metastases at 6, 12, 24, and 36 mo were 44.1%, 21.7%, 14.2%, 7.1%, respectively. The median survival time was 4.9 mo (range, 0-37 mo). Fourteen patients (11%) died of extrahepatic HCC, others died of primary HCC or liver failure. CONCLUSION: The prognosis of HCC patients with extrahepatic metastases is poor. With regard to the cause of death, many patients would die of intrahepatic HCC and few of extrahepatic metastases. Although most of HCC patients with extrahepatic metastases should undergo treatment for the primary HCC mainly, treatment of extrahepatic metastases in selected HCC patients who have good hepatic reserve, intrahepatictumor stage (T0-T2), and are free of portal venous invasion may improve survival. | Kiminori Uka Hiroshi Aikata Shintaro Takaki Hiroo Shirakawa Soo Cheol Jeong Keitaro Yamashina Akira Hiramatsu Hideaki Kodama Shoichi Takahashi Kazuaki Chayama | 2007 | World Journal of Gastroenterology2007，13，3： | 44 |
| 2 | Systemic gemcitabine combined with intra-arterial low-dose cisplatin and 5-fluorouracil for advanced hepatocellular carcinoma: Seven cases显示文摘The combination of intra-arterial low-dose cisplatin and 5-fluorouracil (5-FU) is effective against advanced hepatocellular carcinoma (HCC). Systemic gemcitabine chemotherapy seems effective in many cancers. We report the results of combination therapy with systemic gemcitabine, intra-arterial low-dose cisplatin and 5-FU (GEMFP). Seven patients with non-resectable advanced HCC were treated with GEMFP. One course of chemotherapy consisted of daily intra-arterial cisplatin (20 mg/body weight/hour on d 1, 10 mg/body weight per 0.5 h on d 2-5 and 8-12), followed by 5-FU (250 mg/body weight per 5 h on d 1-5 and 8-12) via an injection port. Gemcitabine at 1000 mg/m2 was administered intravenously at 0.5 h on d 1 and 8. The objective response was 57%. The response to GEMFP was as follows: complete response (no patients), partial response (four patients), stable disease (three patients), and progressive disease (no patients). The median survival period was 8 mo (range, 5-55). With regard to the National Cancer Institute Common Toxicity Criteria (NCI-CTC) grade 3 or 4 adverse reactions, seven (100%), seven, six (86%) and one (14%) patients developed leukopenia, neutropenia, thrombocytopenia and anemia, respectively. GEMFP may potentially be effective for non- resectable advanced HCC, but it has severe hematologic toxicity. | Kiminori Uka Hiroshi Aikata Shintaro Takaki Tomokazu Kawaoka Hiromi Saneto Daiki Miki Shoichi Takahashi Naoyuki Toyota Katsuhide Ito Kazuaki Chayama | 2008 | World Journal of Gastroenterology2008，14，16： | 4 |
| 3 | CT/^(99m)Tc-GSA SPECT fusion images demonstrate functional differences between the liver lobes显示文摘AIM: To evaluate the functional differences between the 2 liver lobes in non-cirrhotic patients by using computed tomography/99mTc-galactosyl human serum albumin (CT/99mTc-GSA) single-photon emission computed tomography (SPECT) fusion images. METHODS: Between December 2008 and March 2012, 264 non-cirrhotic patients underwent preoperative liver function assessment using CT/99mTc-GSA SPECT fusion images. Of these, 30 patients, in whom the influence of a tumor on the liver parenchyma was estimated to be negligible, were selected. Specifically, the selected patients were required to meet either of the following criteria: (1) the presence of an extrahepatic tumor; or (2) presence of a single small intrahepatic tumor. These 30 patients were retrospectively analyzed to calculate the percentage volume (%Volume) and the percentage function (%Function) of each lobe. The ratio between the %Function and %Volume (function-to-volume ratio) of each lobe was also calculated, and the ratios were compared between the 2 lobes. Furthermore, the correlations between the function-to-volume ratio and each of 2 liver parameters [lobe volume and diameter ratio of the left portal vein to the right portal vein (LPV-to-RPV diameter ratio)] were investigated. RESULTS: The median values of %Volume and %Function were 62.6% and 67.1% in the right lobe, with %Function being significantly higher than %Volume (P < 0.01). The median values of %Volume and %Function were 31.0% and 28.7% in the left lobe, with %Function being significantly lower than %Volume (P < 0.01). The function-to-volume ratios of the right lobe (1.04-1.14) were significantly higher than those of the left lobe (0.74-0.99) (P < 0.01). The function-to-volume ratio showed no significant correlation between the lobe volume in either lobe. In contrast, the function-to-volume ratio showed significant correlations with the LPV-to-RPV diameter ratio in both lobes (right lobe: negative correlation, rs = -0.37, P = 0.048; left lobe: positive correlation, r s = 0.71, P < 0.001). The function-to-volume ratio in the left lobe tended to be higher, and that in the right lobe tended to be lower, in accordance with the increase in the LPV-to-RPV diameter ratio. CONCLUSION: CT/99mTc-GSA SPECT fusion images demonstrated that the function of the left lobe was significantly decreased compared with that of the right lobe in non-cirrhotic livers. | Tatsuaki Sumiyoshi Yasuo Shima Ryoutarou Tokorodani Takehiro Okabayashi Akihito Kozuki Yasuhiro Hata Yoshihiro Noda Yoriko Murata Toshio Nakamura Kiminori Uka | 2013 | World Journal of Gastroenterology2013，19，21： | 3 |
| 4 | Effects of a 24-week course of interferon-αtherapy after curative treatment of hepatitis C virus-associated hepatocellular carcinoma显示文摘AIM:To assess whether a 24-wk course of interferon (IFN)could prevent hepatocellular carcinoma(HCC) recurrence and worsening of liver function in patients with hepatitis C virus(HCV)-infected patients after receiving curative treatment for primary HCC. METHODS:Outcomes in 42 patients with HCV infection treated with IFN-α,after curative treatment for primary HCC(IFN group),were compared with 42 matched curatively treated historical controls not given IFN(non- IFN group). RESULTS:Although the rate of initial recurrence did not differ significantly between IFN group and non-IFN group (0%,44%,61%,and 67% vs 4.8%,53%,81%,and 87% at 1,3,5,and 7 years,P=0.153,respectively), IFN group showed a lower rate than the non-IFN group for second recurrence(0%,10.4%,28%,and 35% vs 0%,30%,59%,and 66% at 1,3,5 and 7 years, P=0.022,respectively).Among the IFN group,patients with sustained virologic response(SVR)were less likely to have a second HCC recurrence than IFN patients without an SVR,or non-IFN patients.Multivariate analysis identified the lack of SVR as the only independent risk factor for a second recurrence,while SVR and Child-Pugh class A independently favored overall survival. CONCLUSION:Most intrahepatic recurrences of HCV- related HCC occurred during persistent viral infection. Eradication of HCV is essential for the prevention of HCC recurrence and improvement of survival. | Soo Cheol Jeong Hiroshi Aikata Yoshio Katamura Takahiro Azakami Tomokazu Kawaoka Hiromi Saneto Kiminori Uka Nami Mori Shintaro Takaki Hideaki Kodama Koji Waki Michio Imamura Hiroo Shirakawa Yoshiiku Kawakami Shoichi Takahashi Kazuaki Chayama | 2007 | World Journal of Gastroenterology2007，13，40： | 3 |
| 5 | Low-dose intermittent interferon-alpha therapy for HCV-related liver cirrhosis after curative treatment of hepatocellular carcinoma显示文摘AIM: To assess the efficacy of low-dose intermittent interferon (IFN) therapy in patients with hepatitis C virus (HCV)-related compensated cirrhosis who had received curative treatment for primary hepatocellular carcinoma (HCC). METHODS: We performed a prospective case controlled study. Sixteen patients received 3 MIU of natural IFN- alpha intramuscularly 3 times weekly for at least 48 wk (IFN group). They were compared with 16 matched historical controls (non-IFN group). RESULTS: The cumulative rate of first recurrence of HCC was not significantly different between the IFN group and the non-IFN group (0% vs 6.7% and 68.6% vs 80% at 1- and 3-year, P = 0.157, respectively). The cumulative rate of second recurrence was not also significantly different between the IFN group and the non-IFN group (0% vs 6.7% and 35.9% vs 67% at 1- and 3-year, P = 0.056, respectively). Although the difference in the Child-Pugh classification score between the groups at initial treatment of HCC was not signifi cant, the score was signifi cantly worse at the time of data analysis in the non-IFN group than IFN group (7.19 ± 1.42 vs 5.81 ± 0.75, P = 0.0008). The cumulative rate of deviation from objects of any treatment for recurrentHCC was also higher in the non-IFN group than IFN group (6.7% and 27% vs 0 and 0% at 1- and 3-year, P = 0.048, respectively). CONCLUSION: Low-dose intermittent IFN-alpha therapy for patients with HCV-related compensated cirrhosis after curative HCC treatment was effective by making patients tolerant to medical or surgical treatment for recurrent HCC in the later period of observation. | Soocheol Jeong Hiroshi Aikata Yoshio Katamura Takahiro Azakami Tomokazu Kawaoka Hiromi Saneto Kiminori Uka Nami Mori Shintaro Takaki Hideaki Kodama Koji Waki Michio Imamura Hiroo Shirakawa Yoshiiku Kawakami Shoichi Takahashi Kazuaki Chayama | 2007 | World Journal of Gastroenterology2007，13，39： | 2 |
