Patient and methods: This study was a nonrandomized uncontrolled phase II study and was conducted at clinical oncology department and south Egypt cancer institute;it involved 28 patients with histologically confirmed Ewing’s sarcoma;all of them were subjected to PET/CT whenever possible or MRI with contrast of the primary site, MSCT chest, bone scan, and LDH to ensure absence of metastasis followed by the protocol of accelerated hyper fractionated RT. Results: The overall response rate (ORR) was 92.9% by MRI with significant effect of the type of response on local RFS (P 0.002). The median local RFS of 28 patients with localized Ewing’s sarcoma was 30 ± 8.599 months with 95% CI = 13.147 - 46.853;the 3-year local control was 35%. Conclusion: Accelerated hyper fractionated RT didn’t achieve better results than standard fractionation RT, but it is recommended to be done on a large sample size, and multiple centers, and continued follow up is also recommended to evaluate 5-year LRFS, 5-year OS.展开更多

The correlation among H. pylori infection, heparanase(HPA) and mitogen-activated protein kinase(MAPK) expression, which was determined by immunohistochemistry, and the clinical features of GC was analysed using SPSS 22.0. Overall survival(OS) and relapse-free survival(RFS) of GC patients were estimated by the KaplanMeier method. Independent and multiple factors of HPA and MAPK with prognosis were determined with COX proportional hazards models. HPA and MAPK expression in MKN-45 cells infected with H. pylori was analysed using Western blot. RESULTS H. pylori infection was observed in 70 of 99 patients with GC(70.7%), which was significantly higher than that in healthy controls. H. pylori infection was related to lymph metastasis and expression of HPA and MAPK(P < 0.05); HPA expression was relevant to MAPK expression(P = 0.024). HPA and MAPK expression in MKN-45 cells was significantly upregulated following H. pylori infection and peaked at 24 h and 60 min, before decreasing(P < 0.05). SB203580, an inhibitor of MAPK, significantly decreased HPA expression. HPA was related to lymph metastasis and invasive depth. HPA positive GC cases and H. pylori positive GC cases showed poorer prognosis than HPA negative cases(P < 0.05). COX models showed that the prognosis of GC was connected with HPA expression, lymph metastasis, tissue differentiation, and invasive depth. CONCLUSION H. pylori may promote the invasion and metastasis of GC by increasing HPA expression that may associate with MAPK activation, thus causing a poorer prognosis of GC.展开更多
