Nomograms for predicting the risk of prostate cancer developed using other populations may introduce sizable bias when applied to a Chinese cohort. In the present study, we sought to develop a nomogram for predicting the probability of a positive initial prostate biopsy in a Chinese population. A total of 535 Chinese men who underwent a prostatic biopsy for the detection of prostate cancer in the past decade with complete biopsy data were included. Stepwise logistic regression was used to determine the independent predictors of a positive initial biopsy. Age, prostate-specific antigen (PSA), prostate volume (PV), digital rectal examination (DRE) status, % free PSA and transrectal ultrasound (TRUS) findings were included in the analysis. A nomogram model was developed that was based on these independent predictors to calculate the probability of a positive initial prostate biopsy. A receiver-operating characteristic curve was used to assess the accuracy of using the nomogram and PSA levels alone for predicting positive prostate biopsy. The rate for positive initial prostate biopsy was 41.7% (223/535). The independent variables used to predict a positive initial prostate biopsy were age, PSA, PV and DRE status. The areas under the receiver-operating characteristic curve for a positive initial prostate biopsy for PSA alone and the nomogram were 79.7% and 84.8%, respectively. Our results indicate that the risk of a positive initial prostate biopsy can be predicted to a satisfactory level in a Chinese population using our nomogram. The nomogram can be used to identify and counsel patients who should consider a prostate biopsy, ultimately enhancing accuracy in diagnosing prostate cancer. 展开更多

Objective:Despite being the third commonest cancer in Singaporean men,there is a dearth of basic data on the detection rate of prostate cancer and post-procedure complication rates locally using systematic 12-core biopsy.Our objective is to evaluate prostate cancer detection rates using 12-core prostate biopsy based on serum prostate specific antigen(PSA)levels and digital rectal examination(DRE)findings in Singaporean men presenting to a single tertiary centre.The secondary objective is to evaluate the complication rates of transrectal prostate biopsies.Methods:We retrospectively examined 804 men who underwent first transrectal-ultrasound(TRUS)guided 12-core prostate biopsies from January 2012 to April 2014.Prostate biopsies were performed on men presenting to a tertiary institution when their PSA levels were4.0 ng/mL and/or when they had suspicious DRE findings.Results:Overall prostate cancer detection rate was 35.1%.Regardless of DRE findings,patients were divided into four subgroups based on their serum PSA levels:0e3.99 ng/mL,4.00 e9.99 ng/mL,10.00e19.99 ng/mL and20.00 ng/mL and their detection rates were 9.5%,20.9%,38.4% and 72.3%,respectively.The detection rate of cancer based on suspicious DRE findings alone was 59.2% compared to 36.5% based on serum PSA cut-off of 4.0 ng/mL alone.The post-biopsy admission rate for sepsis was 1.5%.Conclusion:In conclusion,using contemporary 12-core biopsy methods,the local prostate cancer detection rate based on serum PSA and DRE findings has increased over the past decade presumably due to multiple genetic and environmental factors.Post-biopsy sepsis remains an important complication worldwide. 展开更多

We investigated the prostate cancer detection rates upon transrectal ultrasound (TRUS)-guided biopsy in relation to digital rectal examination (DRE) and prostate-specific antigen (PSA), and risk factors of prostate cancer detection in the Chinese population. Data from all consecutive Chinese men who underwent first TRUS-guided prostate biopsy from year 2000 to 2013 was retrieved from our database. The prostate cancer detection rates with reference to DRE finding and PSA level of 〈 4, 4-10, 10.1-20, 20.1-50 and 〉 50 ng ml^-1 were investigated. Multivariate logistic regression analyses were performed to investigate for potential risk factors of prostate cancer detection. A total of 2606 Chinese men were included. In patients with normal DRE, the cancer detection rates were 8.6%, 13.4%, 21.8%, 41.7% and 85.2% in patients with PSA 〈 4, 4-10, 10.1-20, 20.1-50 and 〉 50 ng ml^-1 respectively. In patients with abnormal DRE, the cancer detection rates were 12.4%, 30.2%, 52.7%, 80.6% and 96.4% in patients with PSA 〈 4, 4-10, 10.1-20, 20.1-50 and 〉 50 ng m1-1 respectively. Older age, smaller prostate volume, larger number of biopsy cores, presence of abnormal DRE finding and higher PSA level were associated with increased risk of prostate cancer detection upon multivariate logistic regression analyses (P 〈 0.001). Chinese men appeared to have lower prostate cancer detection rates when compared to the Western population. Taking the different risk factors into account, an individualized approach to the decision of TRUS-guided biopsy can be adopted. 展开更多

Low back pain remains a most common clinical entity among musculoskeletal disorders. Pain reducing modalities, Manual therapy various specific techniques were widely used physiotherapeutic means as part of treatment for subjects with low back pain. An emerging trend with Independent physiotherapy practice, knowing red flags, conditions requiring investigations and experts treatment were to be recognized and adhered for maximizing patients care and benefits. Prostate cancer among men above 50 years were more found to be linked with Low back pain. This original research presentation where a subject having chronic low back pain found to have prostate cancer were analyzed and discussed with scientific evidence on clinical manifestations, investigations and medical management. Underlines the importance of recognizing, directing and getting treated of the root cause of subjects suffering with Low back pain due to prostate cancer and not just keep treating the symptoms alone were major purpose of this study. 展开更多
