SPAG9 promotes prostate cancer proliferation and metastasis via MAPK signaling pathway.

Prostate cancer (PCa) is a worldwide malignant tumor which seriously threats the reproductive health of middle-aged and senior male. Sperm-associated antigen 9 (SPAG9), which belongs to the cancer testis (CT) antigen, overexpressed in multiple human malignant tumors and promoted tumor proliferation, invasion and metastasis. However, little attention has been focused on the relationship between SPAG9 and PCa.

Statin and metformin therapy in prostate cancer patients with hyperlipidemia who underwent radiotherapy: a population-based cohort study.

Purpose: To evaluate the association between the use of statins and/or metformin and patient survival in prostate cancer patients in Taiwan.

Subjects And Methods: Newly diagnosed prostate cancer patients who had hyperlipidemia and received radiotherapy were identified from the National Health Insurance Research Database 2000-2010. The survival rate was estimated by the Kaplan-Meier method.

A modification with threading cannula needle-assisted 4-point suspension fixation for retroperitoneal laparoscopic pyeloplasty in children with ureteropelvic junction obstruction: a cohort study in single center.

Purpose: To evaluate the effect and safety of modifying a threading cannula needle-assisted suspension fixation in retroperitoneal laparoscopic dismembered pyeloplasty (LDP) for children with congenital ureteropelvic junction obstruction (UPJO).

Methods: Between December 2012 and December 2017, 45 children (< 14 years of age) with congenital UPJO were divided into two groups. In Group A, children underwent conventional "no-suspension fixation" LDP; and in Group B, "4-point suspension fixation" LDP was performed to lower difficulties and shorten operative time.

Upregulated circular RNA circ-102004 that promotes cell proliferation in prostate cancer.

Objective: Prostate cancer (PCa) is one of the most prevalent cancers affecting men worldwide. However, the biological functions of circRNAs in PCa are still largely unknown.

Methods: Real-time PCR (RT-PCR) and immunohistochemistry were performed to characterize the circ-102004 expression in both human PCa tissues and cell lines.

Impact and Predictive Value of Prostate Weight on the Outcomes of Nerve Sparing Laparoscopic Radical Prostatectomy in Patients with Low Risk Prostate Cancer.

Purpose: To investigate the impact of prostate weight on outcomes of nerve sparing laparoscopic radical prosta-tectomy (LRP) and assess its predictive value on postoperative continence and potency recovery.

Materials And Methods: We conducted a retrospective study on the clinical data of 165 patients with low risk prostate cancer (PCa) who underwent nerve sparing LRP. All the patients included had normal preoperative uri-nary and sexual function.

A Novel Modification of Transurethral Enucleation and Resection of the Prostate in Patients With Prostate Glands Larger than 80 mL: Surgical Procedures and Clinical Outcomes.

Objective: To evaluate the efficacy and safety of the modified transurethral enucleation and resection of the prostate (M-TUERP) vs the conventional bipolar transurethral resection of the prostate (B-TURP) for the treatment of prostates larger than 80 mL.

Methods: From April 2012 to May 2014, 86 patients with a prostate volume of >80 mL were divided into 2 groups to undergo M-TUERP and B-TURP. In the M-TUERP group, we proposed combining the 12-mm trocar suprapubic cystostomy and using the techniques of "umbrella-shaped resection," "point resection," and "segmental enucleation" to modify the transurethral enucleation and resection of the prostate procedure.

Identification of endonuclease domain-containing 1 as a novel tumor suppressor in prostate cancer.

Background: Endonuclease domain containing 1 (ENDOD1) is implicated in tumorigenesis and aggressiveness of multiple tumors. In this study, we aimed to investigate the role of ENDOD1 in prostate cancer (PCa).

Methods: Immunohistochemistry were performed in 30 cases of benign prostatic hyperplasia (BPH) and 50 cases of PCa to identify its association with clinicopathological characteristics.

Silencing of CDC20 suppresses metastatic castration-resistant prostate cancer growth and enhances chemosensitivity to docetaxel.

The role of cell division cycle 20 (CDC20) was investigated in chemoresistance to decetaxel and the underlying mechanisms in metastatic castration-resistant prostate cancer (mCRPC). MTT assays were performed to determine effects of siRNA-mediated CDC20 knockdown on cell proliferation and anticancer activity of docetaxel. Western blot analyses were conducted to detect changes of Akt and Wnt signaling.

Overexpression of Cdc20 in clinically localized prostate cancer: Relation to high Gleason score and biochemical recurrence after laparoscopic radical prostatectomy.

Objectives: This study was aimed to explore Cdc20 expression and its correlation with clinicopathological characteristics and biochemical recurrence (BCR) after laparoscopic radical prostatectomy (LRP) in clinically localized prostate cancer (PCa).

Methods: Cdc20 expression was examined by immunohistochemistry in 166 cases, including 60 cases of benign hyperplasia of prostate (BPH) patients treated by transurethral resection and 106 cases of consecutive PCa patients treated by LRP without neoadjuvant therapy in a single Chinese institution. The correlation with clinicopathological features and the predictive value for BCR were statistically analyzed.

Laparoscopic Radical Prostatectomy after Previous Transurethral Resection of the Prostate in Clinical T1a and T1b Prostate Cancer: A Matched-Pair Analysis.

Purpose: To analyze and compare surgical, oncological and functional outcomes of laparoscopic radi­cal prostatectomy (LRP) in patients with and without previous transurethral resection of the prostate (TURP).

Materials And Methods: In total, 785 men underwent LRP at our institution from January 2002 to December 2012. TURP had been performed previously in 35 of these patients (TURP group).

Predictors of urinary continence recovery after modified radical prostatectomy for clinically high-risk prostate cancer.

Purpose: To retrospectively determine predictors of urinary continence (UC) recovery in clinically high-risk prostate cancer (PCa) patients treated with modified radical prostatectomy (RP).

Materials And Methods: A total of 184 patients with clinically high-risk PCa who underwent modified RP in a single Chinese center were retrospectively reviewed. Pelvic floor muscle training with biofeedback was routinely performed after catheter removal.

Objective: To investigate the functional and oncologic outcomes of patients with locally advanced or lymph node metastatic prostate cancer (PCa) treated by laparoscopic radical prostatectomy (LRP) in a single Chinese institution.

Methods: From June 2004 to June 2011, a total of 152 cases including 105 locally advanced PCa and 47 lymph node metastatic PCa who were treated by LRP with extended lymph node dissection (ePLND) were enrolled in this study. Surgical records, urinary continence, complications, and oncologic outcomes were presented.

Single-centre study comparing standard apical dissection with a modified technique to facilitate vesico-urethral anastomosis during laparoscopic radical prostatectomy.

A modified apical dissection of the prostate to improve the efficiency of vesico-urethral anastomosis (VUA) in laparoscopic radical prostatectomy (LRP) was reported.
