To clarify the knowledge and beliefs of the Japanese general population related to legal options, pain medications, communication with physicians, and hydration/nutrition in end-of-life care, and to explore the associations between end-of-life care they had experienced and these beliefs, a questionnaire survey was conducted on two target populations: 5000 general population subjects and 866 bereaved family members of cancer patents who died in 12 palliative care units in Japan. The respondents were requested to report the legal knowledge about end-of-life options, pain-related beliefs, communication-related beliefs, and hydration/nutrition-related beliefs, and their experiences with end-of-life care. A total of 3061 responses were analyzed (effective response rate, 54%). The respondents were classified into six groups: no bereavement experience (n = 949), those who had lost family members within the past 10 years from noncancer diseases at institutions (n = 673), those who lost family members from noncancer disease at home (n = 264), those who lost family members from cancer at institutions other than palliative care units (n = 525), those who lost family members from cancer at home (n = 86), and those who lost family members from cancer at palliative care units (n = 548). Across groups, 32-45% and 50-63% of the respondents stated that treatment withdrawal and double effect act were legal, respectively. Between 34% and 44% believed that cancer pain is not sufficiently relieved, 27-38% believed that opioids shorten life, and 24-33% believed that opioids cause addiction. Communication-related beliefs potentially resulting in barriers to satisfactory end-of-life discussion were identified in 31-40% ("physicians are generally poor at communicating bad news") and in 14-25% ("physicians are not comfortable discussing death"). The bereaved family members of the patients who died in palliative care units were significantly more likely than the other groups to believe that cancer pain is sufficiently relieved, and significantly less likely to believe that opioids shorten life, that opioids cause addiction, that physicians are generally poor at communicating bad news, and that physicians are uncomfortable discussing death. Between 33% and 50% of the respondents, including families from palliative care units, believed "artificial hydration should be continued as the minimum standard until death," while 15-31% agreed that "artificial hydration relieves patient symptoms." A significant proportion of the Japanese general population has beliefs about legal options, pain medications, and communication with physicians that potentially result in barriers to quality end-of-life care. As their experiences in specialized palliative care significantly influenced their belief, systematic efforts to spread quality palliative care activity are of value to lessen these barriers and achieve quality end-of-life care.

High levels of serum cytokines at baseline were correlated with poor effects of sorafenib treatment in patients with HCC.

The aim of this study was to determine the carrier rate of hepatitis virus in patients with haematological malignancies and the incidence of liver injury in these patients following chemotherapy. From January 1996 to September 2002, we studied 601 consecutive, unselected series of patients with haematological malignancies admitted in our hospital unit (Japan). They consisted of 246 cases of acute leukaemia, 218 non-Hodgkin's lymphoma (NHL), 13 adult T-cell leukaemia, and 124 multiple myeloma. Of these 601 patients, 373 were men and 228 were women; their mean age was 61 yr, with a range from 18 to 89 yr. The prevalences of hepatitis B virus (HBV) and hepatitis C virus (HCV) were 7.3% and 10.1%, respectively, in NHL, both higher than those in acute leukaemia (1.7% and 2.9%, P < 0.005) and in general Japanese population (1.2% and 2.6%). The incidence of post-chemotherapy liver injury in 25 HBV carriers (36.0%) was significantly higher than that in 539 non-hepatitis virus carriers (12.6%, P = 0.003) and 37 HCV carriers (10.8%, P = 0.026). Liver injury in HBV carriers was more often present in patients who had been treated with steroids than in those without steroids (72.7% and 0%, P = 0.013). After lamivudine became available in our institution, the incidence of liver injury in HBV carriers was reduced from 53.3% to 10.0% (P = 0.041). The therapeutic strategy for haematological malignancies in hepatitis virus carriers should be further investigated.

Comprehensive glycome analysis can be used to know the presence of pancreatic cancer, distant metastasis, and patient prognosis, simultaneously.

Chronic viral hepatitis B and C and non-alcoholic fatty liver disease (NAFLD) have been widely acknowledged to be the leading causes of liver cirrhosis and hepatocellular carcinoma. As anti-viral treatment progresses, the impact of NAFLD is increasing. NAFLD can coexist with chronic viral hepatitis and exacerbate its progression. Oxidative stress has been recognized as a chronic liver disease progression-related and cancer-initiating stress response. However, there are still many unresolved issues concerning oxidative stress, such as the correlation between the natural history of the disease and promising treatment protocols. Recent findings indicate that oxidative stress is also an anti-cancer response that is necessary to kill cancer cells. Oxidative stress might therefore be a cancer-initiating response that should be down regulated in the pre-cancerous stage in patients with risk factors for cancer, while it is an anti-cancer cell response that should not be down regulated in the post-cancerous stage, especially in patients using anti-cancer agents. Antioxidant nutrients should be administered carefully according to the patients’ disease status. In this review, we will highlight these paradoxical effects of oxidative stress in chronic liver diseases, pre- and post-carcinogenesis.
