ABSTRACT
Objective To investigate the effect of the high mobility group protein 1 (HMGB1), cancer embryonic antigen (CEA) and squamous cell carcinoma antigen ( SCC-Ag) by paclitaxel combined with cisplatin chemotherapy in the treatment of advanced esophageal cancer patients .Methods 43 cases advanced esophageal cancer patients from our hospital were selected and randomly divided into the control group and the experiment group.19 cases in the control group were treated by surgery combined with postoperative chemotherapy , 24 cases in the experimental group were treated with surgery and chemotherapy.The clinical efficacy and high mobility group protein 1 ( HMGB1 ) , cancer embryonic antigen ( CEA ) and squamous cell carcinoma antigen ( SCC-Ag ) levels were compared between the two groups before and after treatment.Results The total effective rate of the experimental group was (91.7%) higher than that of the control group (57.9%), the difference was statistically significant (P <0.05).After treatment, the serum levels of SCC-Ag, CEA and HMGB1 were decreased in the two groups, compared with the control group, the experimental group SCC-Ag, CEA and HMGB1 levels were lower, the difference was statistically significant ( P <0.05 ) .There was no significant difference in adverse reactions between the two groups.Conclusion Paclitaxel combined with cisplatin in the treatment of advanced esophageal cancer patients with good results, presumably with the decrease of serum SCC-Ag, CEA and HMGB1 levels in patients with.
ABSTRACT
Objective To investigate the clinical value of radiotherapy combined with xeloda monotherapy in the treatment of elderly patients with rectal cancer.Methods 80 elderly patients with rectal cancer were retrospectively collected.The patients were assigned into study group (n=43) or control group (n=37) according to the treatment way.The study group adopted radiotherapy combined with xeloda,while the control group only treated with radiotherapy.The main indicators included major clinical outcomes (3-year survival rate,recurrence rate,progression free survival),and postoperative health related quality of life and major complications of the two groups were observed.Results Compared with the control group,the 3-year recurrence rate of the study group decreased significantly (25.58% vs.48.65%,x2=4.579,P=0.032);the progression free survival was significantly prolonged [(42.58±7.63)months vs.(34.95±6.30)months,t=7.495,P=0.000];the quality of health related life after 1 year increased significantly [(75.50±8.11) vs.(69.76±9.58),t=3.295,P=0.002].There were no significant differences in postoperative major complications (granulocyte reduction,diarrhea,nausea,vomiting,hand foot syndrome and sensory neuropathy) and 3-year survival rate between the two groups (all P>0.05).ConclusionRadiotherapy combined with xeloda chemotherapy helps improve progression free survival and recurrence rate in elderly patients with rectal cancer.
ABSTRACT
Objective To explore the relationship between the antiviral effect and peripheral blood mononuclear cell (PBMC) hepatitis B virus (HBV) DNA when the patients reach the standard of withdrawal of antiviral therapy in chronic hepatitis B (CHB).Methods Ninety CHB patients treated with interferon(n=44) or nucleot (s) ide(n=46) who reached the standard of withdrawal of antiviral therapy were recruited.HBV DNA levels in PBMCs were tested at the end of treatment,and its relationship with serum HBV DNA level before treatment in PBMC HBV DNA positive group and negative group were compared.The correlation between HBV DNA in PBMCs at the end of treatment and relapse were explored.Measurement data were analyzed by student t test and enumeration data were analyzed by X2 test.Results Among 90 patients,67(74.4%) were PBMC HBV DNA negative at the end of treatment,and 23(25.6%) were positive.The serum HBV DNA positive conversion rate in PBMC HBV DNA negative patients was 13.4%,which were significantly lower than that in positive group (73.9%) (X2=30. 4873, P<0.01 ). There were no significant differences of alanine aminotransferase (ALT) levels when hepatitis flare (t=0. 8729, P=0. 3913) and relapse time (t=1. 9222, P=0. 0665) between PBMC HBV DNA negative group and positive group after withdrawal of therapy, while the serum HBV DNA rebound was greater in positive group than that in negative group (t=2. 7493, P=0. 0112). There were five patients who achieved hepatitis B surface antigen (HBsAg) seroconversion, whose PBMC HBV DNA were all undetectable, and none relapsed during follow-up for 6-12 months. The pretreatment HBV DNA as level in PBMC HBV DNA positive was (7.2±1.1) lg copy/mL, which was much higher than that in negative group[(5.2±2.1) lg copy/mL] (t=4. 3557, P<0.01). Conclusions In patients who reach the standard of drug withdrawal,PBMC HBV DNA at the end of treatment is an important predictor for durability of antiviral therapy in CHB.
