Studying Tumor Tissue Samples From Patients With Melanoma Who Have Undergone Sentinel Lymph Node Biopsy

August 9, 2013 updated by: Leeds Cancer Centre at St. James's University Hospital

A Retrospective Case-Control Study of Melanoma Patients Who Have Undergone Sentinel Lymph Node Biopsy

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help the study of cancer in the future.

PURPOSE: This laboratory study is looking at tumor tissue samples from patients with melanoma who have undergone sentinel lymph node biopsy.

Detailed Description

OBJECTIVES:

  • Develop a predictive model for sentinel lymph node biopsy positivity in patients with melanoma who have undergone sentinel lymph node biopsy.
  • Develop a survival model for relapse based on sentinel lymph node biopsy positivity.
  • Assess the genetic determinants in primary melanomas that predict a metastatic phenotype and thereby improve understanding of the biology of the metastases in melanoma.

OUTLINE: This is a retrospective, case-controlled, multicenter study. Patients are stratified according to Breslow thickness of the tumor (0.75-1.50 mm vs 1.51- 4 mm vs > 4 mm) and gender.

Archived tumor tissue is analyzed by immunohistochemistry (IHC) for AP2, vascular endothelial growth factor, MMP 2, MCM4, and others, if feasible. Sentinel node biopsies are analyzed by IHC for CD31, LYVE-1, and D2-40 expression. RNA and DNA are also extracted for genetic expression studies and mutation analysis (e.g., BRAF, NRAS, PTEN, CDKN2A).

Patient data related to relapse and recurrence is collected, if available.

PROJECTED ACCRUAL: A total of 1,000 patients will be accrued for this study.
