Objective To investigate the efficacy and tolerability of dose-dense chemotherapy with cisplatin plus 5-fluorouracil( PF regimen)in distant metastatic nasopharyngeal carcinoma( NPC)patients. Methods From April 1,2008 to April 30,2014,168 patients were assigned to traditional group(n = 83) and dose-dense group(n = 85)using digital random table in 1 : 1 ratio. All patients received PF regimen,and once every 28 days in traditional group and once every 14 days in dose-dense group. The primary endpoint was progression-free survival(PFS)and the secondary endpoint was overall survival(OS),toxicity and response rate. Results The median PFS,median OS,1,2,3-year survival rate,complete response rate and objective response rate were significantly improved in dose-dense group which were 13. 3 months,20. 2 months,80. 2% , 36. 0% ,16. 1% ,16. 5% ,84. 7% ,and those in control group were 10. 0 months,16. 1 months,59. 6% , 10. 1% ,0,3. 6% ,54. 2% respectively(χ2 = 24. 47,P = 0. 000;χ2 = 16. 65,P = 0. 000;χ2 = 8. 41,P =0. 004;χ2 = 16. 96,P = 0. 000;χ2 = 14. 91,P = 0. 000;χ2 = 7. 63,P = 0. 006;χ2 = 18. 47,P = 0. 000). The rates of grade 3-4 adverse events in dose-dense and traditional group were 38. 8% and 6. 0%(χ2 = 25. 81, P = 0. 000). Conclusion Dose-dense chemotherapy of PF is more efficient and acceptable toxic than the tra-ditional one. It can be a new treatment option for patients with distant metastases of NPC.

To examine the effect of transcatheter arterial embolization (TAE) of liver tumors on hypoxia-inducible factor-1alpha (HIF-1alpha) expression in the residual viable tumor, a total of 30 New Zealand White rabbits implanted with VX2 liver tumor were divided into 2 groups. TAE-treated group animals (n=15) were subjected to TAE with 150-250 mum polyvinyl alcohol particles. Control group animals (n=15) underwent sham embolization with distilled water. Six hours, 3 days or 7 days after TAE, the animals were sacrificed, and samples of tumor and adjacent normal liver tissue were harvested. Expression of HIF-1alpha protein was examined immunohistochemically. Real-time PCR was performed to examine the HIF-1alpha mRNA levels. Our results showed that HIF-1alpha protein was expressed in the VX2 tumors but not in the adjacent normal liver tissue. The HIF-1alpha-positive tumor cells were located predominantly at the periphery of necrotic tumor regions. The mean levels of HIF-1alpha protein were significantly higher in TAE-treated tumors than those in control tumors (P=0.002). Among the three sacrificing time points, the difference in increase in HIF-1alpha protein was significant between the two groups at the sacrificing time point of 6 h and 3 days after TAE (P=0.020, P=0.031, respectively), whereas no significant increase was noted 7 days after TAE (P=0.502). In contrast, although HIF-1alpha mRNA was expressed in TAE-treated and control VX2 tumors, there existed no significant difference in the HIF-1alpha mRNA level between the two groups (P=0.372). It is concluded that TAE of liver tumors increases the expression of HIF-1alpha at protein level in the residual viable tumor, which could be attributed to hypoxia generated by the procedure.

BACKGROUND: Blood hemoperfusion with resin adsorption can clean larger molecules that exceed the molecular weight cutoff of combined continuous veno-venous hemofiltration (CVVH). Hence blood hemoperfusion with resin adsorption combined CVVH (HP+CVVH) has higher ability of mediator clearance, and can improve clinical outcomes in theory. This study aimed to investigate the effect of blood hemoperfusion with resin adsorption combined continuous veno-venous hemofiltration (HP+CVVH) on plasm cytokines like TNF-α, IL-1β, IL-6, cellular immunity and prognosis in patients with multiple organ dysfunction syndrome (MODS). METHODS: This was a prospective, randomized clinical trial. A total of 30 patients who had been diagnosed with MODS were enrolled in this study. Patients were randomly allocated to routine treatment+HP+CVVH group (treatment group) and routine treatment+only CVVH group (control group). In the treatment group, patients received blood hemoperfusion with resin adsorption for 2 hours, and then received CVVH for 10 hours every day. In the control group, patients received CVVH for 12 hours only every day. The patients in the two groups received blood purification therapy for three days. The plasma of patients in the treatment group was obtained at 0, 2, 12, 24, 26, 36, 48, 50, 60 hours, 5th day, 7th day and 10th day, respectively. The plasma of patients in the control group was obtained at 0, 12, 24, 36, 48, 60 hours, 5th day, 7th day and 10th day, respectively. APACHE II score, T-lymphocytes subpopulations, blood lactate acid concentration, heart rate, breathing rate, and oxygenation index were observed. RESULTS: Plasma cytokines like TNF-α, IL-1β, IL-6 decreased markedly after HP (P<0.01);T-lymphocytes subpopulations CD3+, CD4+, CD8+, CD4+/CD8+ increased after HP+CVVH or only CVVH. The plasma concentrations of TNF-α, IL-1β and IL-6 in the two groups were not markedly different at 12, 36, and 50 hours. But on the 5th day, the plasma concentrations of TNF-α, IL-1β and IL-6 in the treatment group were lower than those in the control group (P<0.05). On the 28th day, 5 patients died in the treatment group, and 6 patients in the control group. CONCLUSIONS: Both HP+CVVH and CVVH can clean plasma cytokines like TNF-α, IL-1β, and IL-6, and improve cellular immunity and clinical symptoms and signs of patients. Compared with only CVVH, the plasma concentrations of TNF-α, IL-1β and IL-6 were lower on the 5th day, and patients have an increased survival rate on the 28 day in the HP+CVVH group.
