Prostatic carcinoma is the most commonly diagnosed cancer in the United States in men. Prostatic carcinoma in Korean men is uncommon and accounts for less than 1% of total cancer: however, the incidence of prostatic carcinoma is continuously increasing. Several clinicopathologic parameters including stage, Gleason score, and serum PSA level have been widely accepted as well established prognostic factors. To study the clinicopathologic features of prostatic carcinoma in Korean men, 58 cases of prostatic carcinoma, which were diagnosed on radical prostatectony specimens at Asan Medical Center from Jan. 1993 to June 1998 (1993; 3 cases, 1994; 3, 1995; 6, 1996; 12, 1997; 24, 1998; 10), were evaluated. The prostatic carcinomas were divided into three groups according to Gleason score. Tumors with Gleason score 6 or lower, 7, and 8 to 10 were categorized as low-grade, intermediate-grade and high-grade tumor, respectively. The overall mean age of the patients was 62.6 years (range, 4 6~76 years); mean age was 65.4, 62.8 and 61.1 in low, intermediate and high-grade tumor, respectively (p>0.05). The overall mean serum PSA level was 38.6 ng/ml (range, 0.3~276.0 ng/ml); mean serum PSA level was 17.0, 29.0 and 60.9 ng/ml in low, intermediate and high-grade tumor, respectively (p=0.002). The mean T stage was 2.3, 2.4 and 3.1 in low, intermediate and high-grade tumor (p=0.001). The percentage of positive resection margin was 33.3, 50.0 and 91.0 % in low, intermediate and high-grade tumor (p=0.001). The overall presence of prostatic intraepithelial neoplasia (PIN) was 79.3 %; percentage of the presence of PIN was 100, 79.2 and 68.2 % in low, intermediate and high-grade tumor (p>0.05). As reported in the literature, our results indicated that Gleason score was a good predictor of stage and prognosis. The higher Gleason score, the more cases were with positive surgical margins, advanced pathologic stage, and high serum PSA level (p<0.05).

PURPOSE: The data of Korean men with prostate cancer from a single institute were analyzed to construct nomograms predicting the pathological stage and to compare the outcomes with pre-existing nomograms. MATERIALS AND METHODS: A total of 254 Korean men, with clinically localized prostate cancer, who underwent radical retropubic prostatectomy at Asan Medical Center, between June 1990 and April 2002, were included in this study. A multinomial log-linear regression analysis was performed for the simultaneous prediction of organ-confined disease(OC), seminal vesicle invasion(SVI) or lymph node metastasis(LN) using serum PSA, Gleason scores and clinical stages. Nomograms representing the percentage probabilities were constructed, and compared with the preexisting nomograms presented in the work of Partin et al. and Egawa et al., by calculating the area under the receiver operating characteristics(ROC) curves. RESULTS: Nomograms predicting the likelihood of OC, SVI and LN were derived from the combination of the aforementioned preoperative variables. When the nomograms were compared using the ROC curves, with the Partin table, the areas under the curves were 0.758, 0.762 and 0.766 for OC, SVI and LN, respectively, and with the Egawa table, 0.766 and 0.669 for OC and SVI, respectively. In the multiple measures analysis, which tested the differences between each corresponding data with respect to each preoperative variable, all the tested differences were revealed to be statistically significant. CONCLUSIONS: Comparison of the prediction nomograms revealed notable differences, especially in the OC and SVI. Therefore, it is recommended that each table should be applied to its corresponding population.

Two strains of non-O group 1 Vibrio cholerae (non-0:1V. cholerae) were isolated from blood of a woman who had undergone a gastrectomy and from peritoneal fluid of a man with an impaired liver function. Microbiology laboratories in countries where raw fish and shellfish are frequently consumed should consider the possibility of non-0:1 V. cholerae when they identify vibrios from extraintestinal sources.

We analyzed the prostate cancer data of 317 Korean men with clinically localized prostate cancer who underwent radical prostatectomy at Asan Medical Center between June 1990 and November 2003 to construct nomograms predicting the pathologic stage of these tumors, and compared the outcome with preexisting nomograms. Multinomial log-linear regression was performed for the simultaneous prediction of organ-confined disease (OCD), extracapsular extension (ECE), seminal vesicle invasion (SVI) and lymph node metastasis (LNM) using serum prostate-specific antigen (PSA), Gleason score and clinical stage. Nomograms representing percent probabilities were constructed and compared with those presented by Partin et al. by calculating areas under the receiver operating characteristics (ROC) curves. Median serum PSA at surgery was 10.8 ng/mL, and median biopsy Gleason score was 7. Overall OCD, ECE, SVI and LNM rates were 59.6%, 20.5%, 11.7% and 8.2%, respectively, and areas under the curves were 0.724, 0.626, 0.662, and 0.794, respectively. Pathologic stage of localized prostate cancer in Korean men may be predicted using the Partin table, with acceptable accuracy for OCD and LNM, but less so for ECE and SVI.
