OBJECTIVETo conduct a survival analysis of gastric cancer patients according to the data of population-based cancer registry during 2005-2010 in Zhejiang Province in order to provide information for prognosis assessment and control of this disease.

METHODSThe deadline of the last follow-up of 26, 536 patients was December 31st, 2012. Cumulative observed survival rate (OSR) and expected survival rate were calculated by life table and Hakulinen method.

RESULTSthe 1-, 3-, and 5-year OSR were 58.51%, 39.07%, and 33.08%, and the 1-, 3-, and 5-year relative survival rates (RSR) were 60.24%, 42.90%, and 39.03%, respectively. The 1-, 3-, and 5-year relative survival rates of males vs. females were 60.49% vs. 59.65%, 42.88% vs. 42.96%, and 38.76% vs. 39.64%, respectively, statistically with non-significant differences (χ(2) = 0.13, P > 0.05) between them. The 5-year OSR and RSR of urban patients were 39.15% and 46.30%, and the 5-year OSR and RSR of rural patients were 30.81% and 36.32%, with statistically significant differences between them (P < 0.05). The 15-44 age group had a better relative survival rate.

CONCLUSIONSThe survival rate of gastric cancer patients in Zhejiang Province is low. Work of cancer prevention and control should be strengthened. The wide variation in gastric cancer survival rates between urban and rural patients indicates that priority should be given to rural areas in allocating medical and public health resources.

OBJECTIVETo explore the involvement of hepatitis B X protein (HBx) in promoter 3 (P3)-driven mRNA overexpression of the insulin-like growth factor II gene (IGF-II) and investigate the underlying epigenetic mechanism.

METHODSLevels of P3 and HBx mRNA and status of P3 methylation were analyzed in human hepatocellular carcinoma (HCC) samples, with and without hepatitis B virus (HBV) infection, using quantitative reverse transcription-PCR and bisulfite sequencing. In addition, the levels of P3 mRNA and P3 methylation were examined in HepG2 cells stably overexpressing HBx (HepG2-HBx). Finally, P3 promoter-luciferase constructs were cotransfected into HepG2 cells along with an HBx-expressing plasmid, and the effects of HBx on transcriptional activity and methylation of P3 were analyzed. Statistical analyses of the data were conducted by chi square test, Fisher's exact test, Student's t-test, Marn-Whitney U test, and Pearson's correlation coefficient test.

RESULTSThe HBV-positive HCC specimens had significantly higher levels of P3 mRNA than the HBV-negative HCC specimens (-9.59 ± 3.22 vs. -12.97 ± 3.08 delta CT; P=0.006) but significantly lower levels of P3 methylation (mean values for the 17 CpG sites (36.9% ± 15.5% vs. 52.1% ± 19.1%; P=0.025). The P3 transcript abundance was positively correlated with the level of HBx expression and negatively correlated with the level of P3 methylation. The epigenetic results from experiments with the HepG2-HBx cells were similar. Transfection of HBx significantly decreased P3 methylation level and increased its activity.

CONCLUSIONHBx expression may promote IGF-II expression by inducing hypomethylation of its P3 promoter in hepatocellular carcinoma.

OBJECTIVE:To investigate the role of clinical pharmacists on drug therapy for a chemotherapy patient with drug-induced liver injury (DILI).METHODS:Clinical pharmacists participated in the therapy for a patient with colorectal cancer and suggested that ondansetron+metoclopramide+promethazine were given before chemotherapy for stopping vomiting because chemotherapy drugs might lead to gastrointestinal reaction.The patient suffered from DILI before second chemotherapy.According to the history of drug use and the characteristics of drug effects,clinical pharmacists estimated that DILI may be related to Chinese patent medicine (Guben yichang tablets) and TCM formula granules taken during the two chemotherapy periods.Clinical pharmacists recommended Polyene phosphatidylcholine injection 465 mg,ivgtt,qd+Reduced glutathione for injection 1 g,ivgtt,qd for protecting liver tissue,and additionally recommended Compound glycyrrhizin injection 60 mL,ivgtt,qd for inhibiting inflammation and regulating immune function.After liver function of the patient had been recovered,it was suggested to stop polyene phosphatidylcholine,reduced glutathione and compound glycyrrhizin,etc.Pharmaceutical care was also provided,including efficacy evaluation,ADR monitoring,medication education,telephone follow-up,etc.RESULTS:The physicians adopted the suggestions of clinical pharmacists.The liver function indexes of the patient recovered to normal,and then completed chemotherapy smoothly for 3 times.CONCLUSIONS:When tumor patients suffer from DILI during chemotherapy,clinical pharmacists should help physicians fmd and judge the drug factors leading to DILI based on the history of drug use and the characteristics of drug effects,and assist physicians to formulate and adjust medication plan so as to relieve the degree of DILI and guarantee the smooth development of chemotherapy.

OBJECTIVETo provide reference information for prognosis and control of female cancers by analyzing survival rates of breast, cervical and ovarian cancer patients during 2005-2010 in Zhejiang province.

METHODSThe morbidity and mortality data of 18 133 breast, cervical and ovarian cancer patients whose information were registered in health surveillance zone during 2005-2010 in Zhejiang were analyzed. The December 31(st), 2012 was set as the deadline of survival time. Observed survival rate (OS) and relative survival rate (RS) were calculated using SURV3.01 software and comparison between survival rates was conducted through Hakulinen's likely hood ratio test.

RESULTSThe 5-year OS of breast cancer, cervical cancer, and ovarian cancer were 76.89%, 70.79%, 2.59%, respectively during 2005-2010 in Zhejiang province. The 5-year RS of the three cancers were 80.26%, 73.89%, 55.17%, respectively. The 5-year RS of breast cancer, cervical cancer, and ovarian cancer in urban area were 83.11%, 77.87%, and 57.22% and 78.00%, 72.21%, and 53.83% in rural areas, respectively. The overall RS of urban patients was higher than the rural's (χ(2) = 24.98, 11.55 and 6.62, respectively, all P values < 0.05). The 5-year RS of breast cancer, which was grouped by age, showed that the 15-44 years group was the highest (83.40%), while 65-77 years group was the lowest (74.67%). The 5-year RS of cervical cancer decreased with age, with a 41.73% decrease from 83.83% (15-44 years group) to 42.10% ( ≥ 75 years group). The 15-44 years group showed the highest 5-year RS of ovarian cancer (74.30%), while ≥ 75 years group was the lowest (41.80%).

CONCLUSIONThe prognosis of breast cancer and cervical cancer were relatively optimistic, while the ovarian cancer was not. The prognosis of female cancer patients in urban areas were better than in rural areas.
