Vulvar Cancer
Conditions
Brief summary
The aim of this study is to confirm prospectively if the use of near infrared-indocyanine green (NIR-ICG) alone offers similar accuracy and sensitivity to the gold standard dual technique for sentinel lymph node detection in early stage vulvar cancer.
Interventions
SLNs will be detected with ICG alone, labelled as such, and subsequent to that tested with Gamma probe for accuracy

Eligibility
Inclusion criteria
Adult women (18 years of age) with FIGO Stage IB (\> 1 mm depth of invasion) and small Stage II (4 cm) vulvar squamous cell carcinoma or cutaneous melanoma who are candidates for the Sentinel lymph node technique will be included (Negative clinical groin examination and/or imaging and primary unifocal vulvar tumor size of \< 4 cm).
Exclusion criteria
Women with a prior history of pelvic, vulvovaginal or inguinal radiation, with allergy or hypersensitivity to Technetium or ICG, or Bartholin gland cancer will be excluded.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| false-negative rate of the detection technique using ICG alone compared to ICG and Technetium (Dual method) per groin | 2 years | This will be calculated as the number of groins for which positive SLN were missed using ICG alone; i.e. the number of groins for which ICG did not detect a positive SLN but was detected by ICG and Technetium, divided by the number of groins for which surgery was performed. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 1. The proportion of positive SLN detected by ICG for each groin divided by the total number of positive SLN detected using ICG and Technetium. | 2 years | the unit of analysis is the number of SLN for each groin. |
