Study of Near-Infrared Imaging With Indocyanine Green for Detection of Sentinel Lymph Nodes in People With Vulvar Cancer

Memorial Sloan Kettering Cancer Center22 enrolled

Overview

The purpose of this study is to compare two types of imaging for sentinel lymph node (SLN) mapping in people with early-stage vulvar cancer. The researchers will compare indocyanine green near-infrared (ICG-NIR) imaging with lymphoscintigraphy. All participants in this study will be scheduled for standard surgical treatment at Memorial Sloan Kettering Cancer Center (MSK). This surgical treatment includes SLN mapping (with both lymphoscintigraphy and ICG-NIR imaging) and SLN biopsy.

Conditions

Vulvar Cancer

Interventions

ICG guided sentinel lymph node biopsy

The surgeon will subsequently inject ICG in accordance with the SLN protocol in the operating room and will identify and remove the SLN by use of near-infrared imaging guidance only. Once the surgeon has identified the SLN in this way, he or she will be unblinded to the results of the lymphoscintigraphy and will use the results of preoperative imaging and an intraoperative gamma counter to confirm the SLNs.

Outcomes

Primary Outcomes

success of identifying the SLN

by use of near-infrared imaging with ICG injection. Patients will be eligible for assessment if they undergo attempted SLN mapping by lymphoscintigraphy and near-infrared imaging with ICG injection. The primary endpoint is the accurate identification of the SLN, defined as the uptake of ICG in the proximalmost draining lymph node in the inguinofemoral chain. Evaluate the ability of near-infrared imaging with ICG injection to detect the inguinofemoral SLN in patients with early-stage vulvar cancer, compared with radiocolloid lymphoscintigraphy, the current standard.
