Objective
To explore the effect of kidney transplantation on chronic prostatitis-like symptoms.
Methods
A total of 300 male renal transplant recipients between January 2015 and January 2017 were collected in the study. All recipients received the questionnaire survey of the National Institute of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) preoperatively and at 3 months after transplantation. The score and relevant risk factors were statistically analyzed.
Results
A total of 210 recipients (70.0%) completed questionnaire effectively, in whom 150 (71.4%) had preoperative and 90 (42.9%) had postoperative chronic prostatitis-like symptoms, respectively. In the 210 patients, the preoperative and postoperative pain score was 6.57±3.12 vs. 3.57±3.16 (P<0.001), voiding score was 3.71±2.38vs. 3.29±2.66 (P=0.116), quality of life score was 7.57±1.60 vs. 5.14±2.75 (P<0.001), and the total NIH-CPSI score was 17.86±3.81vs. 12.00±6.65 (P<0.001), respectively. The severity of chronic prostatitis-like symptoms was alleviated significantly after kidney transplantation.
Conclusion
Kidney transplantation can alleviate the chronic prostatitis-like symptoms significantly, and improve the quality of life in uremia patients.
Prostate cancer ranks second among the causes of death of malignant tumors in middle-aged and elderly men. A considerable number of patients are not easily detected in early-stage prostate cancer. Although traditional imaging examinations are of high value in the diagnosis and staging of prostate cancer, they also have certain limitations. With the development of nuclear medicine instruments and molecular probes, molecular imaging is playing an increasingly important role in the diagnosis and treatment of prostate cancer. Positron emission tomography and computed tomography (PET/CT) using prostate-specific membrane antigen (PSMA) as a probe has gained increasing recognition. This article will review the latest progress in the application of PET/CT using probes for targeting PSMA to imaging and treatment of prostate cancer, in order to provide a theoretical basis for the application of probes for targeting PSMA in the diagnosis and treatment of prostate cancer.
Objective To comprehensively evaluate the association between TNF-α gene ?308 G/A polymorphism and the risk of prostate cancer. Methods A meta-analysis was performed to analyze the association between ?308 G/A polymorphism and the risk of prostate cancer risk. Results A total of 11 case-control studies (4 919 cases and 5 210 controls) were included in this meta-analysis. The result showed no statistically significant differences in all genotype distribution between prostate cancer cases and controls: dominant model (OR=1.11, 95%CI 0.90 to 1.36, P=0.33), recessive model (OR=0.91, 95%CI 0.70 to 1.18, P=0.47), GA versus GG (OR=1.11, 95%CI 0.90 to 1.37, P=0.33), AA versus GG (OR=0.92, 95%CI 0.71 to 1.20, P=0.55), A versus G (OR=1.07, 95%CI 0.91 to 1.26, P=0.39). In the subgroup analysis by ethnicity, no statistically differences were found between prostate cancer cases and controls. Conclusion This results of meta-analysis suggests that TNF-α gene –308G/A polymorphism may not be a risk factor of prostate cancer. Due to the limited quantity of the includied studies, further studies are needed to validate the above conclusion.
ObjectiveTo systematically review the correlation between Survivin expression and prostate cancer, as well as its clinicopathologic features in Chinese population.
MethodsSuch databases as PubMed, EMbase, CBM, CNKI, VIP and WanFang Data were electronically searched from inception to November, 2015 to collect case-control studies about the correlation between Survivin expression and prostate cancer, as well as its clinically pathologic characteristics in Chinese population. Two reviewers independently screened literature, extracted data and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.3 software.
ResultsA total of 32 case-control studies were included, involving 1613 prostate cancer cases, 708 benign prostatic hyperplasia cases, and 93 controls. The results of meta-analysis showed that the prostate cancer group had a higher Survivin expression level when compared with the benign prostatic hyperplasia group (OR=32.95, 95% CI 19.88 to 54.63, P<0.00001) or the control group (OR=75.78, 95% CI 26.97 to 212.98, P<0.00001). Moreover, the expression level of Survivin was higher in the low and medium differentiation group than in the high differentiation group (OR=4.45, 95% CI 3.13 to 6.32, P<0.00001), higher in the stage of C+D than in the stage of A+B (OR 5.42, 95% CI 2.91 to10.10, P<0.00001), and higher in the prostate cancer with lymph node metastasis than in the prostate cancer without lymph node metastasis (OR 4.07, 95% CI 2.91 to 10.10, P<0.00001).
ConclusionCurrent evidence indicates that the expression level of Survivin is significantly correlated with prostate cancer and its clinicopathologic features in Chinese population. Due to the limited quantity and quality of included studies, above conclusions need to be verified by conducting more high quality studies.
The incidence of prostate cancer ranks the second in malignant tumors among elderly males. Multi-parametric MRI (Mp-MRI) is an important mean for detection, staging, and grading of prostate cancer. In order to standardize the collection, interpretation, and reporting of prostate MRI data, the European Urogenital Radiology Society launched the Prostate Imaging Reporting and Data System (PI-RADS) in 2012. Due to some limitations in the application process, the Joint Committee of the American Society of Radiology and the European Society of Radiology issued an updated version of PI-PADS V2 in 2014. In recent years, some studies have been carried out on the effectiveness, accuracy, and consistency of the diagnosis of prostate cancer. This article will review the application and research status of PI-RADS V2 system in the diagnosis of Mp-MRI for prostate cancer.
Objective Evidence-based medicine was used to make an individualized treatment plan for newly diagnosed prostatic hyperplasia in an elderly patient. Methods After clinical problems were discovered, evidence was collected from CBM, CNKI, The Cochrane Library, PubMed, EMBASE, ScienceDirect, Springer, and ProQuest databases according to our predefined search strategy. The search was done through 2008. The internal and external validity of the evidence was assessed. The evidence, combined with the patient value, was applied to the patient. Results A total of 39 systematic reviews involving 137 randomized controlled trials were identified. A rational treatment plan was made upon a critical evaluation of the data. After one year follow-up, the treatment protocol was proven correct. Conclusion The treatment efficacy in newly diagnosed prostatic hyperplasia in the elderly has been improved by determining an individualized treatment protocol according to evidence-based methods.
ObjectiveTo analyze the disease burden of prostate, bladder and kidney cancers attributable to smoking in China from 1990 to 2019. MethodsBased on the global burden of disease study 2019, the current situation of the disease burden of prostate, bladder and kidney cancers attributable to smoking was analyzed by using the population attributable fraction (PAF), deaths and disability-adjusted life years (DALYs). Furthermore, the annual percent change (APC) and the average annual percent change (AAPC) were calculated by joinpoint regression analysis to describe the long-term trends of the smoking-attributable burden of these three cancers from 1990 to 2019. ResultsThere were an estimated 18 800 cases of deaths and 393 106 person-years of DALYs for bladder cancer caused by smoking in 2019. The age-standardized mortality and DALY rate decreased by 0.41% and 0.39% per year from 1990 to 2019, respectively. For prostate cancer, smoking was estimated to have caused 5 016 cases of deaths and 98 276 person-years of DALYs in 2019. The age-standardized mortality and DALY rate decreased by 0.28% and 0.25% per year from 1990 to 2019, respectively. For kidney cancer, the deaths and DALYs attributable to smoking were 4 935 cases and 120 620 person-years, respectively. The standardized mortality and DALY rates increased by 3.03% and 2.98% per year from 1990 to 2019. Additionally, males suffered from a higher disease burden of these three cancers attributable to smoking than females. The elderly population had a higher smoking-attributable disease burden than the younger population. ConclusionThe situation of the disease burden of bladder, prostate and kidney cancers attributable to smoking is still serious in China, which has substantial disparities in different groups. Specifically, males and the elderly are the high-risk groups for the smoking-attributable burden. Among the three cancers, bladder cancer has the highest burden and kidney cancer has the largest burden increase during 1990-2019.
ObjectiveTo evaluate the efficacy and safety of prostat in combination with antibiotic on the treatment of chronic proatatitis.
MethodsWe searched the literatures which were randomized controlled trials (RCT) on the treatment of combination of prostat and antibiotic for chronic prostatitis published between January 2003 and August 2013 in the Databases including CNKI, Wanfang database, VIP, CBM, PubMed, according to the demand of Cochrane Colloboration, combining computer retrieval with manual retrieval. The quality of literature was assessed by using Jadad scale and extract data from literature. Meta-analyses were performed by using the RevMan 5.1 Software.
ResultsA total of 12 clinical RCT, involving 3 947 patients were identified. One study was double-blind and three studies were single-blind. Only one study had a Jadad scale score of 3, belonging to high quality document; the rest had a score of 2 or 1, and all were low quality documents. The results of the Meta-analysis showed that compared with the control groups, the treatment of combination of prostat with gatifloxacin on chronic prostatitis had a significant difference in total effective rate[OR=3.98, 95%CI (2.67, 5.94), P<0.000 01], NIH-CPSI score[WMD=-6.45, 95%CI(-7.55, -5.34), P<0.000 01]; the treatment of combination of prostat with Levofloxacin on chronic prostatitis had a significant difference in total effective rate[OR=1.71, 95%CI (1.43, 2.05), P<0.000 01], NIH-CPSI score[WMD=-2.85, 95%CI(-3.39, -2.31), P<0.000 01].
ConclusionThe treatment of combination of prostat with antibiotic was superior to the treatment of prostat or antibiotics on chronic prostatitis. It is an effective therapeutic schedule. But the safety of the treatment of combination of prostat and antibiotic on chronic prostatitis needs further evaluation.
