OBJECTIVE
To explore whether levels of nerve growth factor (NGF) in expressed prostatic secretions (EPS) are correlated with symptom severity in chronic prostatitis (CP) and chronic pelvic pain syndrome (CPPS).
PATIENTS AND METHODS
All patients with CP/CPPS underwent a complete history and physical examination, and were scored according to the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI).
Expressed prostatic secretion samples from 20 patients with CP/CPPS and from four asymptomatic control patients were collected and frozen, and NGF levels in EPS were measured by enzyme-linked immunosorbent assay.
Patients were asked to complete NIH-CPSI questionnaires at baseline and 8 weeks after treatment and patients with at least a 25% decrease in total NIH-CPSI score from the baseline values were classified as responders to treatment.
RESULTS
The mean (+/-SD) NGF levels in EPS of patients with CP/CPPS and asymptomatic control patients were 7409 (+/-3788) pg/mL and 4174 (+/-1349) pg/mL, respectively. The NGF level in patients with CP/CPPS correlated directly with pain severity (P = 0.014, r = 0.541).
There were no significant differences between NGF levels in EPS before and after treatment. However, successful treatment significantly decreased NGF levels in responders (P = 0.001).
CONCLUSION
Nerve growth factor might contribute to the pathophysiology of CP/CPPS as changes in NGF level in EPS occurred in proportion to pain severity. Therefore, these results suggest that NGF could be used as a new biomarker to evaluate the symptoms of CP/CPPS and the effects of treatment.

Expression levels of the novel tumor suppressor gene REIC/Dkk-3 are reduced in many human cancers. We have previously showed that an adenovirus vector carrying REIC/Dkk-3 (Ad-REIC) induced apoptosis of cancer cells selectively and exerted bystander antitumor effects via ER stress. We examined possible effects of Ad-REIC in a peritoneal dissemination model of scirrhous gastric carcinoma (SGC). Among various types of gastric cancer, SGC continues to be associated with the worst prognosis due to a high incidence of metastases in the peritoneal cavity. We found that a single intraperitoneal injection of Ad-REIC suppressed tumor dissemination and disease progression. Immunomodulation by Ad-REIC led to recruitment of natural killer cells inside tumor nodules. We conclude that Ad-REIC gene therapy may be a potential tool in combinatorial approaches to achieve curative effects in SGC.

We analyzed the prognostic factors influencing survival after surgeries for upper urinary tract urothelial carcinoma (UUT-UC) with longer follow-up periods than in previous studies. Between January 2000 and December 2004, 386 patients underwent nephroureterectomy for UUT-UC. The data for the 221 patients with UUT-UC were retrospectively reviewed. Nine variables were evaluated for association with the survival outcomes of disease-specific survival. The prognostic significance was tested univariately with the log-rank test. The simultaneous effects of multiple prognostic factors were estimated by multiple regression analysis using the Cox proportional hazards model. The median follow-up was 38.4 months. The 5-year over all survival was 62.3%. Significant prognostic factors for disease-specific survival rate on univariate analysis were pathological stage (p < 0.0001), tumor grade (p = 0.0324), and venous invasion (p < 0.0001). Multivariate analysis revealed that only venous invasion was significant for disease-specific survival rate (p = 0.0205). Venous invasion was the only independent prognostic factor in pathologically localized UUT-UC.

The tumor suppressor REIC/Dkk-3 is a secretory protein which was originally identified to be downregulated in human immortalized cells In the present study, we investigated the expression pattern of REIC/Dkk-3 in various cell types to characterize its physiological functions We first examined the expression level of REIC/Dkk-3 in a broad range of cancer cell types and confirmed that it was significantly downregulated in all of the cell types We also examined the tissue distribution pattern in a variety of normal mouse organs Ubiquitous REIC/Dkk-3 protein expression was observed in the organs The expression was abundant in the liver, heart and brain tissue, but was absent in the spleen and peripheral blood mononuclear cells The immunohistochemical analyses revealed that the subcellular localization of REIC/Dkk-3 had a punctate pattern around the nucleus, indicating its association with secretory vesicles In cancer cells stably transfected with REIC/Dkk-3 the protein was predominantly localized to the endoplasmic reticulum (ER) under observation with confocal microscopy Because REIC/ Dkk-3 was found to be abundantly expressed in the acinar epithelial cells of the mouse prostate, we analyzed the effects of recombinant REIC/Dkk-3 protein on the acinar morphogenesis of RWPE-1 cells, which are derived from human normal prostate epithelium Statistically significant acinar growth was observed in the culture condition with 10 mu g/m1 REIC/Dkk-3 protein, implicating the soluble form m prostatic acinar development Current results suggest that REIC/Dkk-3 may play a role in regulating the morphological process of normal tissue architecture through an autocrine and/or paracrine manner

To verify the indication of diagnostic ureteropyeloscopy based on clinical features for upper urinary tract urothelial cancer with over 100 patients and over a 10-year series.
From January 1997 to December 2008, consecutive 129 units in 124 patients underwent ureteropyeloscopy to obtain a definitive diagnosis of upper urinary tract cancer or to rule out a malignancy. Patients were divided into four subgroups based on voided urine cytology and preoperative radiographic findings: group A (n = 8), positive urine cytology and positive radiographic findings; group B (n = 4), positive cytology and negative radiographic findings; group C (n = 55), negative cytology and positive radiographic findings and group D (n = 62), gross hematuria originating from the upper urinary tract with negative cytology and negative radiographic findings. Ureteropyeloscopic findings were compared with radiographic and cytological results. Adverse effects were also investigated.
In group A, all patients had confirmed cancer. In group B, one revealed small cancer and the remaining three confirmed carcinoma in situ by biopsy with ureteropyeloscopy. In groups C and D, 33 patients (60%) and four (6.5%) revealed cancer. Seventy-eight patients out of 80 (97.5%) in groups C and D were confirmed to have benign disease. No patient was found with malignancy during follow up after negative finding of ureteropyeloscopy.
Ureteropyeloscopy can help in detecting upper urinary tract cancer or to rule out malignancy for patients with negative voiding cytology. However, ureteropyeloscopy is redundant for patients with positive radiographic findings and positive voiding cytology.
