Association of the LPA gene polymorphisms with coronary artery disease risk in the Xinjiang population of China: A case-control study.

Lipoprotein(a) is a well-known independent risk factor for coronary artery disease (CAD) and primarily determined by variation in the LPA gene coding for the apolipoprotein(a) moiety. Our study purpose was to evaluate the association between the human LPA gene polymorphisms and CAD in Han and Uyghur populations in Xinjiang, China. A case-control study was conducted with 831 Han people (392 CAD patients and 439 control subjects) and 829 Uygur people (513 CAD patients and 316 control subjects). All participants were genotyped for the same 3 single nucleotide polymorphisms (rs1801693, rs6923877, and rs9364559) of the LPA gene by a Real-time PCR instrument. In CAD patients, the levels of lipoprotein(a) were significantly higher in the Han population with the C/C genotype at the rs1801693 (P = .018) and the A/A genotype at the rs9364559 (P = .029) than in the Uyghur population. The polymorphisms rs1801693, rs6923877, and rs9364559 were found to be associated with CAD in the Han population. For men, the distribution of rs1801693 in genotypes, alleles and recessive model (CC vs CT + TT) showed a significant difference (all P < .05), and the difference in recessive model was retained after adjustment for covariates (odds ratio [OR]: 0.557, 95% confidence interval [CI]: 0.355-0.874, P = .011). But the distribution of rs6923877 in genotypes and dominant model (GG vs AG + AA) showed a significant difference (both P < .05) in both men and women, and the difference was kept in dominant model after adjustment (OR: 1.473, 95% CI:1.009-2.148, P = .045). For women, a significant difference was found in the distribution of rs9364559 in the alleles and dominant model (AA vs AG + GG) (for alleles: P = .021, for dominant model: P = .025, OR: 0.560, 95% CI:0.350-0.898, P = .016) after adjustment. Polymorphisms rs1801693, rs6923877, and rs9364559 of the LPA gene are associated with CAD in the Han population in Xinjiang Uygur Autonomous Region of China.

S-1 for treatment of advanced hepatocellular carcinoma: a systematic review of the literature.

Hepatocellular carcinoma (HCC) is the most common liver neoplasm worldwide. Based on its potent inhibition of dihydropyrimidine dehydrogenase (DPD), S-1 is expected to be more active than other fluoropyrimidines against HCC with DPD activity. This systematic review was aimed to assess the efficacy and safety of S-1 for treatment of advanced HCC. PubMed, the Cochrane Library, EMBA-SE, and ClinicalTrials.gov were searched using the terms "Hepatocellular Carcinoma" or "HCC" or "Hepatoma" or "Liver cancer" and ''S-1''. Outcomes of main interest included overall survival (OS) and toxicities. We identified four studies of S-1 treatment alone from 1059 references, including a total of 272 patients. There were two original articles and two conference abstracts. The percentage of male patients ranged from 88 to 91.3% and median age ranged from 59 to 70 years. Median OS ranged from 8.6 to 16.5 months. The incidences of toxicity of more than 50% were thrombocytopaenia and fatigue. According to the original description, toxicities were acceptable. The current evidence from the available clinical studies suggests that S-1 may be an effective and tolerable treatment for advanced HCC. Further clinical studies are warranted to further investigate this treatment option.

Transcatheter arterial chemoembolisation (TACE) plus S-1 for the treatment of BCLC stage B hepatocellular carcinoma refractory to TACE.

AIM OF THE STUDY: To assess the efficacy and safety of transcatheter arterial chemoembolization (TACE) plus S-1 for the treatment of Barcelona Clinic Liver Cancer (BCLC) Stage B HCC refractory to TACE. MATERIAL AND METHODS: 26 patients meeting the eligibility criteria were enrolled. TACE was given on day 1, and S-1 on days 2-15. Tumor assessment was performed one month later according to mRECIST. The primary endpoints were TTP and OS. RESULTS: Twenty-six patients received 176 TACE interventions in all. Fifteen patients of TACE plus S-1 received a total of 55 cycles of treatment of S-1, with a median of 4 cycles (range, 2-6). The total dose of S-1 was 6165 mg per day, while average was 120 mg (range, 100-125 mg) for 15 patients of TACE plus S-1. Median TTP and OS of TACE plus S-1 were 6 months (95% CI: 4.7-7.3) and 18 months (95% CI: 15.3-24.7), respectively, while TACE monotherapy was 4 months (95% CI: 2.4-5.6) and 13 months (95% CI: 9.8-16.2), respectively, and significant differences were detected. Though there were higher DCRs in patients of TACE plus S-1, no significant differences were detected. A total of 612 adverse events occurred during the course of the treatment, 367 in TACE plus S-1 and 245 in TACE mono-therapy. There were significant differences to anorexia and nausea, but they were tolerable. CONCLUSIONS: TACE plus S-1 in the present analysis was tolerable and associated with an interesting TTP and OS. TACE plus S-1 may be used as a new treatment method to BCLC Stage B HCC refractory to TACE.
