Urothelial-type mucinous adenocarcinoma of the prostate: A case report and review of the literature / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the clinical manifestations, pathological characteristics, and treatments of urothelial-type mucinous adenocarcinoma of the prostate (UMAP).</p><p><b>METHODS</b>We reported a case of UMAP, reviewed relevant literature, and analyzed the clinicopaothological features, diagnosis, treatment, and prognosis of the disease.</p><p><b>RESULTS</b>The patient was a 60-year-old male and underwent transurethral resection of the prostate for dysuria. Postoperative pathology indicated mucinous adenocarcinoma and sigmoidoscopy revealed no primary colon cancer. Immunohistochemical staining showed the negative expressions of PSA and P504s and positive expressions of CK7, CK34 β E12, CK20, and CDX2. Thus UMAP was confirmed and treated by intensity-modulated radiotherapy. Then the patient was followed up for 30 months, which showed desirable therapeutic result, with neither local progression nor distant metastasis.</p><p><b>CONCLUSION</b>UMAP has a bad prognosis and its diagnosis depends on pathological and immunohistocchemical examinations. It responds well to radical prostatectomy but is not sensitive to endocrine therapy. Radiotherapy can be considered for those who are not fit to receive radical prostatectomy.</p>

Expression and significance of macrophage migration inhibitory factor in bladder urothelial cell carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate the expression and clinical significance of macrophage migration inhibitory factor (MIF) in patients with bladder urothelial cell carcinoma.</p><p><b>METHODS</b>Immunohistochemical staining for MIF was performed on tissue sections of 110 patients with bladder urothelial cell carcinoma and 10 normal controls, and the correlations between MIF and clinicopathological characteristics and prognosis were also analyzed.</p><p><b>RESULTS</b>Normal bladder urothelium from control subjects showed negative or weak staining of MIF. Of the cancer specimens, 72/110 (65.5%) showed a moderate to strong staining of MIF. The expression of MIF protein was found predominantly in the tumor cell cytoplasm and inversely correlated with tumor stage. 27 cases also showed a positive intranuclear staining of MIF, which was inversely correlated with tumor grade, stage and tumor size. Kaplan-Meier analysis showed that the expression of MIF in the cell nuclei was associated with disease-free survival for the cancer patients, but multivariate analysis showed that MIF was not an independent prognostic factors.</p><p><b>CONCLUSIONS</b>The expression of MIF in non-muscle invasive bladder cancer tissues was more frequently than that in muscle-invasive disease, the positive staining of MIF in cell nuclei might be a favorable biomarker for patients with bladder urothelial cell carcinoma.</p>

Prevalence and related factors of prostatitis-like symptoms in young men / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the prevalence and related factors of prostatitis-like symptoms among young men.</p><p><b>METHODS</b>The study was a cross-sectional survey of 2500 young men aged 18-30 years in the city of Weifang, and all of them completed a questionnaire on prostatitis. The univariate and multivariate logistic regression procedures were used to investigate the risk factors among the young men with chronic prostatitis-like symptoms.</p><p><b>RESULTS</b>The valid response rate was 85% (n = 2125). Of the 128 subjects (6.02%) identified as having chronic prostatitis-like symptoms, the mean age was 21.8 years, the average pain score was 6.98 +/- 0.29, and the average voiding score was 3.77 +/- 0.25. Of the sampled population, 39 men had prostatitis-like symptoms with an index pain score of 8 or more. Significant risk factors include frequent masturbation, prolonged sitting, long-time fixed posture, cold environment, stress at home and work.</p><p><b>CONCLUSION</b>The study suggested that chronic prostatitis-like symptoms are common among young men, and the urethritis history, frequent masturbation, prolonged sitting, long-time urine holding, cold environment, and stress at home and work might be significant risk factors.</p>
