The relationship between intolerance of uncertainty and anxiety in men on active surveillance for prostate cancer

Anxiety may serve as a major barrier to participation in AS. Intolerance of uncertainty—the tendency to perceive the potential for negative events as threatening—has been linked to cancer-related worry. Accordingly, we explored prospectively the relationship of intolerance of uncertainty with anxiety along with other clinical factors among men managed with AS for prostate cancer.

Treatment Effects of WST11 Vascular Targeted Photodynamic Therapy in Urothelial Cell Carcinoma and Feasibility, Safety, and Long Term Outcomes in the Upper Urinary Tract of Swine

Surgical management of upper tract urothelial carcinoma requires removal of kidney and ureter, compromising renal function. Non-surgical alternatives have potentially prohibitive safety concerns. We examine the feasibility and safety of ablation of the ureter and renal pelvis using endoluminal vascular-targeted photodynamic therapy in a porcine model and report efficacy of WST11 vascular-targeted photodynamic therapy in a murine model.

Role of Protease-Activated Receptor 2 in the development of lower urinary tract dysfunction

Lower urinary tract symptoms are a common finding in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). We reported that the mast cell-tryptase-PAR2 axis plays a critical role in the development of chronic pain in experimental autoimmune prostatitis (EAP), a mouse model of CP/CPPS. We therefore examined whether PAR2 activation mediates lower urinary tract dysfunction.

A Specific Mapping Study Using Fluorescence Sentinel Lymph Node Detection in Patients with Intermediate- and High-risk Prostate Cancer Undergoing Extended Pelvic Lymph Node Dissection


Sentinel lymph node (SLN) detection techniques have the potential to change the standard of surgical care for patients with prostate cancer. We performed a lymphatic mapping study and determined the value of fluorescence SLN detection with indocyanine green (ICG) for the detection of lymph node metastases in intermediate- and high-risk patients undergoing radical prostatectomy and extended pelvic lymph node dissection. A total of 42 patients received systematic or specific ICG injections into the prostate base, the midportion, the apex, the left lobe, or the right lobe. We found (1) that external and internal iliac regions encompass the majority of SLNs, (2) that common iliac regions contain up to 22% of all SLNs, (3) that a prostatic lobe can drain into the contralateral group of pelvic lymph nodes, and (4) that the fossa of Marcille also receives significant drainage. Among the 12 patients who received systematic ICG injections, 5 (42%) had a total of 29 lymph node metastases. Of these, 16 nodes were ICG positive, yielding 55% sensitivity. The complex drainage pattern of the prostate and the low sensitivity of ICG for the detection of lymph node metastases reported in our study highlight the difficulties related to the implementation of SNL techniques in prostate cancer.

Patient summary

There is controversy about how extensive lymph node dissection (LND) should be during prostatectomy. We investigated the lymphatic drainage of the prostate and whether sentinel node fluorescence techniques would be useful to detect node metastases. We found that the drainage pattern is complex and that the sentinel node technique is not able to replace extended pelvic LND.

Take Home Message

Fluorescence detection of the lymphatic landing sites of the prostate demonstrates a complex drainage pattern, suggesting that lymph node metastases do not follow a predefined pathway of metastatic spread. Our study also shows that the sensitivity of this technique to detect metastases is low.
