RESUMEN
Objective To investigate the relationship between preoperative albumin-to-alkaline phosphatase ratio and overall survival (OS) after radical cystectomy of bladder cancer.Methods The clinical date of patients with bladder cancer who underwent radical cystectomy and urinary diversion and confirmed by pathology from Jan 2007 to Dec 2015 were analyzed retrospectively,with 140 cases undergoing laparoscopic surgery and 26 cases undergoing open surgery.There were 148 males and 18 females,aged was 33-85 years,with an ayerage ageof (65.1 ± 9.4) years.There were 55 cases of cutaneous ureterostomy,96 cases of Brick diversior with ileum,and 15 cases of ileal neobladder.The AAPR range 0.03-1.67,with an average 0.62 ± 0.23,and body mass index (BMI) was 16.79-32.65 kg/m2,with an average of (24.00 ± 3.32) kg/m2.There were 33 cases with hydronephrosis and 133 no hydronephrosis,31 cases with hypertension and 135 cases no hypertension,and 14 cases with diabetes and 152 cases no diabetes.Four cases were classified as grade0,65 cases as grade 1,86 cases as grade 2,and 11 cases as grade 3.Based on the preoperative AAPR(0.62 ±0.23),they were divided into three groups,with 55 cases in the low AAPR (0.42 ± 0.09) group,55 cases in the middle AAPR (0.58 ± 0.05) group,and 56 cases in the high AAPR (0.86 ± 0.21)group.Cox proportional hazards regression methodology were used to evaluate the relationship between preoperative AAPR and overall survival.Survival analysis was conducted using the Kaplan-Meier method and compared with the log-rank test.Results 166 patients were followed up for 1-144 months,with a median of 63 months,and 71 cases died and 95 survived.The median serum AAPR level in all cases was 0.59 (range 0.03-1.67).Results of univariate Cox regression model revealed that AAPR(HR =0.09,95％ CI 0.022-0.391,P =0.001),high AAPR (HR=0.40,95％CI0.216-0.742,P=0.003),age (HR =2.42,95％ CI 1.294-4.531,P =0.006),tumor size (HR =2.11,95％ CI 1.112-4.014,P =0.023),pT3 stage (HR=8.93,95％CI3.173-25.114,P＜0.001),pT4 stnge(HR =10.39,95％ CI 3.110-34.707,P ＜0.001),pN1 stage(HR =2.80,95％ CI 1.422-5.531,P =0.003),pN3 stage (HR =17.06,95％ CI2.192-132.863,P =0.007),pathological grade (HR =0.30,95％ CI 0.113-0.817,P =0.019),hydronephrosis (HR =2.36,95 ％ CI 1.406-3.939,P =0.001),adjuvant chemotherapy (HR =2.66,95％ CI 1.674-4.247,P ＜ 0.001)were associated with OS.Compared with patients in the lowest of AAPR,the risk for death in the highest AAPR group decreased about 59％ (HR =0.406,95％ CI 0.200-0.822,P =0.012)after adjustment for age,BMI,tumor size,number of tumor,T category,N category,pathological grade,hydronephrosis,ASA level,adjuvant chemotherapy in multiple Cox regression models.Each unit increase in the AAPR was associated with about 80％ decreased risk of death (HR =0.199,95％ CI 0.051-0.779,P =0.020) after adjusting for the confounding variables.After adjusting for age,BMI,tumor size,number of tumor,T category,N category,pathological grade,hydronephrosis,ASA level,adjuvant chemotherapy,the curve fitting results showed that with the increase of AAPR,the risk of death decreased and the overall survival prolonged.Consistent with the linear trend test results,the relationship between AAPR and OS is linear.Conclusions AAPR was associated with overall survival of patients who underwent radical cystectomy of bladder cancer.
RESUMEN
Objective:To analyze the utilization of analgesics in ten cancer hospitals in China from 2013 to 2016;to analyze the use sta-tus of analgesics and auxiliary analgesics in Chinese patients with cancer, based on the three-step analgesic ladder principle an-nounced by the WHO and the guidelines of National Comprehensive Cancer Network(NCCN),and to provide data for the rational use of cancer analgesics in clinical practice.Methods:A retrospective analysis method was used to extract data on the use of analgesics and auxiliary analgesics in ten cancer hospitals in China between 2013 and 2016.Subsequently,statistical analyses were conducted on the dosage form of the drugs,the total consumption,the defined daily doses(DDDs),the defined daily cost(DDC),and the drug se-quence ratio(B/A).Results:Between 2013 and 2016,patients using analgesics in China comprised 12.6% of the total number of can-cer patients and the cost of analgesics accounted for 1.5% of the total cost of medication for all patients.The main analgesics used were opioids,which accounted for 90.9% of the cost of analgesics;the other types of analgesics,such as the anticonvulsant drugs, were increased.The major administration routes of analgesics in patients were oral,injectable,and topical routes.The DDD rankings of all types of analgesic treatment drugs were basically stable.The DDD values of fentanyl patches,estazolam,oxycodone oral dosage form,morphine oral dosage form,and indomethacin suppository were among the best.The DDC values for most analgesics did not change much,which reflected that price was stable.The DDC values of 13 analgesics were between 10 and 100.Most of the B/A val-ues of all kinds of analgesics were close to 1,with 17 between 0.5 and 1.5,comprised 58.6% of all types of drugs,which indicated that medication synchronization was good.Conclusions:The clinical applications of analgesics are increasing.In China,the treatment of cancer pain generally follows the three-step analgesic ladder principle announced by the WHO.However,there are also some prob-lems.For instance,the daily average cost of a few drugs was high and the synchronization was poor.Therefore,it is necessary to im-prove the management and regulate the treatment of cancer pain.
RESUMEN
OBJECTIVE:To systematically review the relationship of clinical efficacy between XPD Lys751Gln (A/C),XPD Asp312Asn(G/A)and platinum-based chemotherapy in patients with advanced non-small cell lung cancer(NSCLC),and provide evidence-based reference for clinical treatment. METHODS:Retrieved from PubMed, Cochrane Library, EMBase, Medline, CJFD,VIP database and WanFang database,studies about the effects of XPD Lys751Gln and XPD Asp312Asn polymorphism on ef-fectiveness,clinical outcomes and adverse drug reaction of platinum-based chemotherapy in advanced NSCLC patients were collect-ed,and Meta-analysis was performed by using Rev Man 5.3 software. RESULTS:Totally 30 studies were included,involving 5 028 patients. Genetic testing showed that XPD Lys751Gln divided into mutant gene (Lys/Gln + Gln/ Gln) and wild-type gene (Lys/Lys),while XPD Asp312Asn divided into mutant gene (Asp/Asn + Asn/Asn) and wild-type gene (Asp/Asp). Results of Me-ta-analysis showed,the progression-free survival (PFS) of Lys/Gln+Gln/Gln patients with platinum in XPD Lys751Gln polymor-phism was obviously lower than Lys/Lys patients [OR=-1.12,95%CI(-1.73,-0.50),P<0.001],while there was no significant difference in the chemotherapy effectiveness and total survival period. The effective rate of Asp/Asn+Asn/Asn patients for platinum in XPD Asp312Asn polymorphism was lower than Asp/Asp patients [OR=0.80,95%CI(0.68,0.96),P=0.02],while there was no significant difference in the total survival period and PFS. Meanwhile,the incidence of Ⅲ-Ⅳ level gastrointestinal adverse reac-tions of Lys/Gln+Gln/Gln with platinum in XPD Lys751Gln polymorphism was higher than Lys/Lys patients [OR=0.43,95%CI (0.20,0.94),P=0.03],and there was no significant difference in Ⅲ-Ⅳ level blood system adverse reactions. CONCLUSIONS:XPD Lys751Gln polymorphism may be associated with PFS and Ⅲ-Ⅳ level gastrointestinal adverse reactions for advanced NSCLC patients with platinum-based chemotherapy,while XPD Asp312Asn polymorphism may have effect on platinum-based chemotherapy,both of them may be as estimate the chemotherapy effect and prognosis detection index of platinum-based chemo-therapy.
