简要总结

This study aims to evaluate the feasibility of indocyanine green (ICG)-based fluorescence imaging in the detection of prostate tumors and metastatic lymph nodes. By correlating the ICG fluorescence patterns with pathologically confirmed tumor and nodal status, it would be possible to use fluorescence navigation system in helping prostate biopsy and lymph node dissection in the future.

详细描述

The investigators will conduct an in vivo and in vitro pilot study in order to evaluate the diagnostic performance of fluorescence in the detection of prostate cancer and metastatic lymph nodes. All the patients included in this study will receive a radical prostatectomy after intravenous injection of 0.4 mg/Kg of ICG. ICG will be administered immediately after the patient is anesthetized. The fluorescence analysis will be performed intraoperatively by laparoscopic imaging and after surgery by hand-held imaging. The prostate or lymph nodes specimen with or without fluorescence signal will be sent to the Department of Pathology for pathological analysis. The histopathological procedure will be performed without knowledge of fluorescence analysis.

研究组 & 干预措施

ICG injection group

Experimental

ICG will be intravenously administered over a 10 second period immediately after the patient was anesthetized. The fluorescence will be performed during and after the surgery, respectively.

干预措施: Indocyanine Green (ICG) (Drug)

结局指标

主要结局

sensitivity (true positive) and specificity (true negative) of the ICG-based fluorescence to detect prostate cancer in vivo and in vitro compared to histological analysis

次要结局

  • sensitivity and specificity of the ICG-based fluorescence imaging to detect metastatic lymph nodes(1 week post-surgery)
