ICG-based Fluorescence Imaging in Localization of Prostate Cancer and Metastatic Lymph Nodes

July 18, 2016 updated by: Rongqin Zheng, Third Affiliated Hospital, Sun Yat-Sen University

A Pilot and Feasibility Study of Indocyanine Green-based Fluorescence Imaging in Localization of Prostate Cancer and Metastatic Lymph Nodes

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • Histologically confirmed prostate cancer;
  • Able to accept total prostatectomy;
  • Patient has given its informed consent.

Exclusion Criteria:

  • Allergic to ICG or iodine;
  • High-grade hepatic insufficiency
  • refuse attending the study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
sensitivity and specificity of the ICG-based fluorescence to detect prostate cancer
Time Frame: 1 week post-surgery
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
1 week post-surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
sensitivity and specificity of the ICG-based fluorescence imaging to detect metastatic lymph nodes
Time Frame: 1 week post-surgery
sensitivity (true positive) and specificity (true negative) of the ICG-based fluorescence to detect metastatic lymph nodes in vivo and in vitro compared to histological analysis
