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.展开更多

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.展开更多

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.展开更多
