ABSTRACT
Objective@#This study investigated the characteristics of progestin-insensitive endometrioid endometrial cancer (EEC) and atypical endometrial hyperplasia (AEH) patients receiving fertility-sparing treatments and assessed the therapeutic effects of second-line fertility-preserving treatments. @*Methods@#Three hundred and thirty-eight patients with EEC (n=75) or AEH (n=263) receiving fertility-preserving treatment were retrospectively analyzed. ‘Progestin-insensitive’ was defined as meeting one of the following criteria: 1) presented with progressed disease at any time during conservative treatment, 2) remained with stable disease after 7 months of treatment, and/or 3) did not achieve complete response (CR) after 10 months of treatment. Clinical characteristics and treatment results of progestin-insensitive patients receiving second-line treatment and those of progestin-sensitive patients were compared. @*Results@#Eight-two patients (59 AEH and 23 EEC) were defined as progestin-insensitive and 256 as progestin-sensitive. In multivariate analysis, body mass index ≥28.0 kg/m2 (odds ratio [OR]=1.898) and lesion size >2 cm (OR=2.077) were independent predictors of progestin-insensitive status. Compared to AEH patients, progestin-insensitive EEC patients had poorer second-line treatment responses (28-week cumulative CR rate after changing second-line treatment, 56.3% vs. 85.4%, p=0.011). No statistical difference was found in CR rate among different second-line treatments. @*Conclusion@#Obesity and larger lesion size were independent risk factors associated with progestin-insensitive status. In progestin-insensitive patients receiving second-line treatment, EEC patients had lower CR rate comparing with AEH patients. Further study with larger sample size is needed to evaluate efficacy of different second-line treatments for progestin insensitive patients.
ABSTRACT
Objective To investigate the expression and clinical significance of platelet glycoprotein CD62p,CD63 and neutrophil surface CD64 in sepsis.Methods Fifty-six children with sepsis from March 2010 to March 2013 in Communicable Disease Department of our hospital were divided into severe sepsis group(n =16) and general sepsis group (n =40),normal control group included 34 subjects from health check.CD62p,CD63 and CD64 were detected by flow cytometry in children with sepsis,and compared with normal control group.Results The levels of CD62p,CD63 and CD64 in severe sepsis group were higher than those of general sepsis group (P ＜ 0.01).The levels of CD62p,CD63 and CD64 in general sepsis group were higher than those of normal control group (P ＜ 0.01).Correlation analysis indicated that CD62p and CD63 were in positive correlation with CD64 in children with sepsis(r =0.817,0.796,P ＜0.001).The positive correlations of CD62p,CD63 and CD64 with pediatric critical illness score were also found(CD62p:r =0.883,P ＜0.001;CD63:r=0.862,P ＜0.001;CD64:r=0.805,P ＜0.001).Conclusion CD62p,CD63 and CD64 are closely related to the severity of infection and diseases,and may be used as immune parameters for the estimation of the clinical severity and the prognosis of acute and severe diseases.
ABSTRACT
Purpose:The efficacy of evaluation of changes of tumoral uptake of 3'-deoxy-3'-[~(18)F] fluorothymidine (FLT) was comparatively analyzed with that of ~(18)F-FDG at early stage after anticancer chemotherapy.Materials and Methods:Cells derived from human lung adenocarcinoma were incubated with cisplatin (CDDP),5-fluorouracil(5-FU),doxorubicin (Dox),for 1,4,24 and 72h.The doses(CD-DP: 67 μM; 5-FU 1,540 μM;MTX: 440 μM;) were determined corresponding to a estimated 10% - 95% proliferation inhibition.The cells were allowed to recover before FLT or FDG being added into the culture media for 60 min.Cell counts,viability,estimated by MTT method,were used to evaluate the cytotoxic effects of chemotherapy.Results: FLT uptake was increased significantly at 1 and 4 h after treatment with 5-FU( 145 ± 12%,150 ± 14%,P <0.01).decreased at 24 h and 72 h.In contrast,FLT accumulation was significantly reduced at cytostatic concentrations of CDDP at different time.The uptake of FDG did not change significantly at early time points after treatment,but decreased at 72 h.Conclusion: The tumor cell uptake of FLT revealed specific changes depending on the auti-cancer drug used at much earlier time than FDG after chemotherpay.
