Radiotherapy(RT) is one of the principle treatment options for prostate cancer.Modern RT and surgery show similar progression-free survival in localized prostate cancer.Adjuvant RT compared to observation significantly diminishes the risk of prostate-specific antigen (PSA) progression and local failure for patients at the highest risk for recurrence after radical prostatectomy,including with seminal vesicle invasion,extraprostatic extension,extensive positive margins,and detectable postoperative PSA.Salvage RT is effective at controlling local recurrence and reduces the risk of distant metastasis and prostate cancerspecific mortality (PCSM) for patients with PSA or local recurrence after prostatectomy.Hypofractionated radiotherapy of recent years' reports shows similar cancer control rates without an increased risk of late toxicity in comparison to conventional regimens.The addition of androgen-deprivation therapy (ADT) to radiation improves the overall survival and biochemical progression-free survival(bPFS) for intermediate-risk and high-risk patients.

Objective To investigate the expressions of tumor suppressor gene FEZ1 and hypoxia inducible factor (HIF)-1α in oral squamous cell carcinoma (OSCC), and their correlation with clinicopathological features and prognosis. Methods A total of 146 specimens of OSCC and 80 normal oral mucosa were used to detect the expressions of FEZ1 and HIF-1αby immunohistochemistry. Thirty specimens of fresh OSCC tissues, 30 samples of the paracancerous tissues and 30 normal mucosa tissues were also included in the study. The relationship between the expressions of FEZ1 and HIF-1α, the clinicopathological features and the prognosis of the patients were analyzed. Western blot assay was used to detect the expres?sions of FEZ1 and HIF-1αin 30 fresh OSCC tissues, 30 samples of the paracancerous tissues and 30 normal mucosa tissues. Results In OSCC tissues, the positive rate of FEZ1 protein (30.14%) was significantly lower than that in normal oral muco?sa (81.25%), and the positive rate of HIF-1αprotein (71.23%) was significantly higher than that in normal mucosa (12.50%,χ2=54.076 and 71.317, P<0.01). There was a correlation between the expression of FEZ1 and clinical stage, tumor size and differentiation. The expression of HIF-1αwas correlated with gender, lymph node metastasis, tumor size and differentiation. There was no significant difference in 5-year survival rate between positive and negative FEZ1 expression groups. The 5-year survival rate was significantly lower in HIF-1α positive expression group than that of HIF-1α negative expression group (P<0.05). The expression level of FEZ1 was decreased by the sequences in normal oral mucosa, paracancerous tissue and OSCC (P<0.01), but the expression level of HIF-1αwas increased in turn (P<0.01). Conclusion FEZ1 and HIF-1αmay be involved in the occurrence and progress of OSCC. The expressions of FEZ1 and HIF-1αcan be used as a reference for the biological behavior of OSCC.

Objective:To investigate the expression of serum microRNA (miR)-92 in patients with liver cancer and its relationship with poor prognosis.Methods:The clinical data of 70 patients with liver cancer in the First People′s Hospital of Huzhou City, Zhejiang Province and the Central Hospital of Huzhou City, Zhejiang Province from May 2015 to May 2018 were retrospectively analyzed. The miR-92 expression level was detected by real-time quantitative polymerase chain reaction method and compared with that of 80 healthy subjects. Receiver operating characteristic (ROC) curve was drawn to evaluate the efficacy of serum miR-92 in diagnosing liver cancer and early stage (stage Ⅰ to Ⅱ) liver cancer. The relationship between serum miR-92 expression level and clinicopathological characteristic was analyzed. Independent risk factors affecting the prognosis in patients with liver cancer were analyzed by multivariate Cox regression model.Results:The expression level of serum miR-92 in patients with liver cancer was significantly higher than that in healthy subjects (4.10 ± 1.74 vs 1.88 ± 0.78), and there was statistical difference ( P<0.05). ROC curve analysis result showed that the area under curve (AUC) of serum miR-92 for the diagnosis liver cancer was 0.874, the best cut-off value was 2.43, the sensitivity was82.86%, and the specificity was 86.25%; the AUC of serum miR-92 for the diagnosis early liver cancer was 0.755, the best cutoff value was 2.38, the sensitivity was 68.57%, and the specificity was 84.42%. The serum miR-92 expression level was related to TNM stage and lymph node metastasis ( P<0.01), but not related to gender, age, tumor diameter, history of hepatitis, liver cirrhosis, degree of differentiation and portal vein tumor thrombus ( P>0.05). The 5-year overall survival rate in liver cancer patients with high serum miR-92 expression was significantly lower than that in liver cancer patients with low serum miR-92 expression (17.1% vs. 31.5%), and there was statistical difference ( χ2 = 5.561, P<0.05). Multivariate Cox regression analysis result showed that miR-92 was an independent risk factor affecting the prognosis in patients with liver cancer ( HR = 0.282, 95% CI 1.179 to 3.562, P<0.05). Conclusions:The expression level of serum miR-92 in patients with liver cancer is significantly increased, which plays an important role in the progression of the disease. Serum miR-92 can be used as an indicator for early diagnosis and prognosis evaluation of liver cancer.

Thiopurine S-methyltransferase (TPMT) is an important and key cytoplasmic enzyme in the metabolism of thiopurine drugs,whose activity can directly determine the amount of thiopurine drugs metabolized to cytotoxic 6-thioguanine nucleotides and consequently influence clinical efficacy and adverse drug reactions of thiopurine drugs.In order to deepen knowledge and role of genetic polymorphism of tpmt in the individualized thiopurine drug treatment,this present review mainly covered the following three frequently concerned aspects,including i) whether or not to determine the activity of TPMT priot to treatment of thiopurine drugs;ii) to genotype or to phenotype;iii) how to choose genotype methods.
