BACKGROUND: We hypothesized that a cut-off in positive lymph node (LN) counts may discriminate between cancer-specific mortality (CSM) rates in clinically localized prostate cancer patients treated with radical prostatectomy (RP). OBJECTIVE: To test this relationship, we relied on different LN count cut-offs, as well as the continuously coded number of positive LNs (NPN). METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2014), we identified patients with D'Amico intermediate- or high-risk characteristics who underwent RP and pelvic LN dissection, regardless of pathologic LN stage...

BACKGROUND: Tumor-associated macrophages (TAMs) constitute a subset of nonneoplastic cells in tumor stroma and influence cancer progression in solid tumors. The clinical significance of TAMs in urinary bladder cancer (UBC) is controversial. METHODS: We prospectively studied 103 patients with stage pT1-T4 UBC treated with cystectomy and pelvic lymph node dissection. Tumor sections were immunostained with M2-specific macrophage marker CD163 and proliferation marker Ki-67...

PURPOSE OF REVIEW: Superparamagnetic iron oxide nanoparticles (SPIONs) are tested to identify sentinel lymph nodes (SLNs) to exploit the advantages of targeted pelvic SLN dissection (sPLND), while circumventing the disadvantages of established radioactive labeling. Here we review recent studies about sPLND in prostate cancer (PCa), including the first results of SLN detection using intraprostatic SPION-injection. RECENT FINDINGS: A recent systematic literature review reveals that the diagnostic accuracy of sPLND is comparable with extended PLND (ePLND)...

OBJECTIVES: Classically, radical cystectomy (RC) involves hysterectomy and bilateral salpingo-oophorectomy (BSO). Current understanding of ovarian cancer pathogenesis and effect of premature oophorectomy has lead to a shift within gynecology toward risk-reducing salpingectomy without oophorectomy in the absence of gynecologic malignancy. The purpose of this study was to assess knowledge base and practice patterns of urologic oncologists with regard to management of the gynecological organs at the time of RC...

INTRODUCTION: To date, bilateral pelvic lymph node dissection (PLND) represents the most accurate and reliable staging procedure for the detection of lymph node invasion in prostate cancer and bladder cancer. However, the procedure is not devoid of complications. In this field, Indocyanine green fluorescence-guided sentinel lymph node (SLN) identification is an emerging and promising technique, as accurate staging of urologic cancer could be enhanced by a thorough evaluation of the sentinel lymph nodes...

Objectives: Traditionally anterior prostatic fat (APF) hasn't been included in pelvic lymph node (LN) dissection templates following radical prostatectomy. In this study we evaluate the incidence of lymphoid tissue in the APF and the incidence of LN metastasis in APF in patients who have undergone robotic-assisted laparoscopic radical prostatectomy (RALP). Methods: A prospective database of RALP has been maintained between January 2010 and September 2015. APF is routinely excised and sent separately for histopathological evaluation to identify lymphoid tissue and metastatic prostate cancer...

Sentinel lymph node dissection (sLND) using a magnetometer and superparamagnetic iron oxide nanoparticles (SPIONs) as a tracer was successfully applied in prostate cancer (PCa). Radioisotope-guided sLND combined with extended pelvic LND (ePLND) achieved better node removal, increasing the number of affected nodes or the detection of sentinel lymph nodes outside the established ePLND template. We determined the diagnostic value of additional magnetometer-guided sLND after intraprostatic SPION-injection in high-risk PCa...

OBJECTIVES: The standard treatment for FIGO stage 1B1 cervical cancer is radical hysterectomy (RH) [1]. Indocyanine-green (ICG) is a drug injected within the cervical stroma to detect the sentinel lymph node (SLN) in cervical cancer [2,3]. ICG travels through the lymphatic channels in the lateral parametrium, which results enhanced with green, before reaching the SLNs. This could help identifying the surgical landmarks. The aim of this video is to propose a new approach to perform parametrial dissection as part of RH under the guidance of ICG...

A late-relapse germ cell tumor might contain malignant non-germ cell tumors, known as 'somatic-type malignancy (SM)'. The development of a secondary SM is rare, and this phenomenon remains poorly understood. Case 1 developed lung metastasis 13 years after chemotherapy followed by retroperitoneal lymph node dissection for stage IIA non-seminoma. The tumor increased in size after chemotherapy. The patient underwent a pneumonectomy. Pathology revealed an adenocarcinoma with immature teratoma. The patient has experienced no relapse for 9 years...

Background: Urinary continence and erectile function (EF) are best preserved when meticulous dissection of prostate and nerve sparing technique are used during radical prostatectomy (RP). However, extent of lymph node dissection (LND) may also adversely affect functional results. Objective: To determine whether performing a super-extended LND (seLND) has a significant effect on recovery of urinary continence and EF after RP. Design setting and participants: All patients who underwent RP from January 2007 until December 2013 were handed questionnaires assessing continence and EF...
