Asian Journal of Andrology 2015年第5期17卷 811-814,I0009页

Only 54% of prostate cancer cases in Korea are localized compared with 82% of cases in the US. Furthermore, half of Korean patients are upgraded after radical prostatectomy （41.6%-50.6%）. We investigated the risk factors for upgrading and/or upstaging of low-risk prostate cancer after radical prostatectomy. We retrospectively reviewed the medical records of 1159 patients who underwent radical prostatectomy at five hospitals in Honam Province. Preoperative data on standard clinicopathological parameters were collected. The radical prostatectomy specimens were graded and staged and we defined a ＂worsening prognosis＂ as a Gleason score ≥ 7 or upstaging to ≥ pT3. Multivariate logistic regression models were used to assess factors associated with postoperative pathological upstaging. Among the 1159 patients, 324 were classified into the clinically low-risk group, and 154 （47.5%） patients were either upgraded or upstaged. The multivariable analysis revealed that the preoperative serum prostate-specific antigen level （odds ratio [OR], 1.131; 95% confidence interval [CI], 1.007-1.271; P = 0.037）, percent positive biopsy core （OR： 1.018; 95% CI： 1.002-1.035; P = 0.032）, and small prostate volume （≤30 ml）（OR： 2.280; 95% CI： 1.351-3.848; P = 0.002） were predictive of a worsening prognosis. Overall, 47.5% of patients with low-risk disease were upstaged postoperatively. The current risk stratification criteria may be too relaxed for our study cohort.

Effect of serum testosterone and percent tumor volume on extra-prostatic extension and biochemical recurrence after laparoscopic radical prostatectomy

Asian Journal of Andrology 2016年第1期18卷 54-59页

Several studies have revealed that the preoperative serum testosterone and percent tumor volume （PTV） predict extra-prostatic extension （EPE） and biochemical recurrence （BCR） after radical prostatectomy. This study investigated the prognostic significance of serum testosterone and PTV in relation to EPE and BCR after laparoscopic radical prostatectomy （LRP）. We reviewed 520 patients who underwent LRP between 2004 and 2012. PTV was determined as the sum of all visually estimated tumor foci in every section. BCR was defined as two consecutive increases in the postoperative prostate-specific antigen （PSA）〉0.2 ng ml^-1. The threshold for serum total testosterone was 3.0 ng ml^-1, Multivariate logistic regression was used to define the effect of variables on the risk of EPE and BCR. A low serum testosterone （〈3.0 ng ml^-1） was associated with a high serum PSA, Gleason score, positive core percentage of the prostate biopsy, PTV, and all pathological variables. On multivariate analysis, similar to previous studies, the serum PSA, biopsy positive core percentage, Gleason score, and pathological variables predicted EPE and BCR. In addition, low serum testosterone （〈3.0 ng ml^-1, adjusted OR, 8.52; 95% CI, 5.04-14.4, P = 0.001） predicted EPE and PTV （adjusted OR, 1.02; 95% CI, 1.01-1.05, P = 0.046） predicted BCR. In addition to previous predictors of EPE and BCR, low serum testosterone and PTV are valuable predictors of EPE and BCR after LRP.

作者： Won Seok Jang In Sang Hwang Eu Chang Hwang Seung Il Jung dong deuk kwon Chan Choi Departments of Pathology Chonnam National University Medical School Gwangju South Korea Departments of Urology Chonnam National University Medical School Gwangju South Korea

Renal cell carcinoma can metastasize to virtually any organ, yet synchronous metastasis to the bladder is extremely rare. A 77-year-old woman presented with gross hematuria. Abdominal and chest computed tomography showed a bilateral renal masses, bladder dome mass, and multiple lung metastasis. Transurethral resection of the bladder tumor and sonography guided renal biopsy were performed. Both pathology diagnoses were clear cell renal cell carcinoma. Targeted therapy using pazopanib was administered to the patient without surgical resection of primary tumors and metastatic lung lesions. Herein, we report the synchronous metastasis of renal cell carcinoma to the bladder and lung.

Prostate calculi in cancer and BPH in a cohort of Korean men：presence of calculi did not correlate with cancer risk

引用

Asian Journal of Andrology 2010年第2期12卷 215-220页

作者： Eu-Chang Hwang Hyang-Sik Choi Chang-Min Im Seung-II Jung Sun-Ouck Kim Tack-Won Kang dong-deuk kwon Kwang-Sung Park Soo-Bang Ryu Department of Urology Chonnam National University Medical School Gwangju 501-75 7 Korea

Prostatic calculi are common and are associated with inflammation of the prostate. Recently,it has been suggested that this inflammation may be associated with prostate carcinogenesis. The aim of this study was to investigate the relationship between prostatic calculi and prostate cancer （PCa） in prostate biopsy specimens. We retrospectively analyzed 417 consecutive patients who underwent transrectal ultrasonography （TRUS） and prostate biopsies between January 2005 and January 2008. Based on the biopsy findings,patients were divided into benign prostatic hyperplasia and PCa groups. TRUS was used to detect prostatic calculi and to measure prostate *** correlations between PCa risk and age,serum total PSA levels,prostate volume,and prostatic calculi were analyzed. Patient age and PSA,as well as the frequency of prostatic calculi in the biopsy specimens,differed significantly between both the groups （P〈0.05）. In the PCa group,the Gleason scores （GSs） were higher in patients with prostatic calculi than in patients without prostatic calculi （P = 0.023）. Using multivariate logistic regression analysis,we found that patient age,serum total PSA and prostate volume were risk factors for PCa （P = 0.001）,but that the presence of prostatic calculi was not associated with an increased risk of PCa （P = 0.13）. In conclusion,although the presence of prostatic calculi was not shown to be a risk factor for PCa,prostatic calculi were more common in patients with PCa and were associated with a higher GS among these men.

Most organic electrode materials （OEMs） for rechargeable batteries employ n-type redox centers, whose redox potentials are intrinsically limited <3.0 V versus Li+/Li. However, p-type materials possessing high redox potentials experience low specific capacities because they are capable of only a single redox reaction within the stable electrochemical window of typical ***, we report 5,11-diethyl-5,11-dihydroindolo[3,2-b]carbazole （DEICZ） as a novel p-type OEM, exhibiting stable plateaus at high discharge potentials of3.44 and 4.09 V versus Li+/Li. Notably, the second redox potential of DEICZ is within the stable electrochemical window. The mechanism of the double redox reaction is investigated using both theoretical calculations and experimental measurements, including density functional theory calculations, ex situ electron spin resonance, and X-ray photoelectron spectroscopy. Finally,hybridization with single-walled carbon nanotubes （SWCNT） improves the cycle stability and rate performance of DEICZ owing to theπ–πinteractions between the SWCNT and co-planar molecular structure of DEICZ, preventing the dissolution of active materials into the electrolyte. The DEICZ/SWCNT composite electrode maintains 70.4%of its initial specific capacity at 1-C rate and also exhibits high-rate capability, even performing well at 100-C rate.
