RATIONALE: Lymphatic mapping may improve the ability to detect cancer of the vulva.
- Determine the negative predictive value of a negative sentinel lymph node in patients with invasive squamous cell carcinoma of the vulva.
- Determine the location of the sentinel node in these patients.
OUTLINE: Patients receive injection(s) of isosulfan blue into the dermis at the junction of the tumor and normal vulvar skin. Once the afferent lymphatic channel and sentinel node have been identified, patients undergo unilateral or bilateral inguinal-femoral lymphadenectomy followed by resection of the primary tumor with adequate margins. Preoperative lymphoscintigraphy is also performed.
Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter or until recurrence.
PROJECTED ACCRUAL: A total of 40-630 patients will be accrued for this study within 2-6 years.
Primary Purpose: Treatment
isosulfan blue, conventional surgery, sentinel lymph node biopsy

RATIONALE: Diagnostic procedures, such as thoracoscopic sentinel lymph node biopsy, may help find breast cancer that has spread to lymph nodes between the breasts. It may also help doctors...
RATIONALE: Diagnostic procedures such as sentinel lymph node biopsy may improve the ability to detect breast cancer and determine the extent of disease. PURPOSE: Phase II trial to study t...
RATIONALE: Diagnostic procedures, such as lymph node mapping during surgery and sentinel lymph node biopsy, may help doctors find micrometastases and predict cancer recurrence. PURPOSE: T...
We continue to collect information in support of the hypothesis that the histology of the first draining lymph node (sentinel node) accurately predicts the histology of the rest of the axi...
Sentinel lymph node (SLN) resection is imperative for breast cancer staging. Axillary reverse mapping (ARM) can preserve arm draining nodes and lymphatics during surgery. ARM is generally performed wi...

Despite clear guidelines for its use and wide adoption, no population-based study has examined the extent to which patients with early stage breast cancer are benefiting from sentinel lymph node biops...
Complete lymph node dissection (CLND) after a positive sentinel node (SN) biopsy provides important prognostic information in melanoma patients but has been questioned for therapeutic use recently. We...
In 2010, the National Comprehensive Cancer Network (NCCN) recommended sentinel lymph node biopsy (SLNB) for thin melanomas ≤1 mm with mitotic rate (MR) ≥1. In 2016, the criteria were changed to Br...
First lymph node to receive drainage from the primary tumor. SENTINEL LYMPH NODE BIOPSY is performed to determine early METASTASIS status because cancer cells may appear first in the sentinel node.
A diagnostic procedure used to determine whether LYMPHATIC METASTASIS has occurred. The sentinel lymph node is the first lymph node to receive drainage from a neoplasm.
Surgical excision of one or more lymph nodes. Its most common use is in cancer surgery. (From Dorland, 28th ed, p966)
Malignant lymphoma in which the lymphomatous cells are clustered into identifiable nodules within the LYMPH NODES. The nodules resemble to some extent the GERMINAL CENTER of lymph node follicles and most likely represent neoplastic proliferation of lymph node-derived follicular center B-LYMPHOCYTES.
The local lymph node assay (LLNA) is an alternative method for the identification of chemicals that have the ability to cause skin sensitization and allergic contact dermatitis. Endpoints have been established so fewer animals are required and less painful procedures are used.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
