Summary of "Cutaneous Squamous Cell Carcinoma Tumour Size is Associated with Sentinel Lymph Node Metastasis in a Cohort of 69 Patients."

Ten to fifty percent of high-risk cutaneous squamous cell carcinoma may potentially metastasize. However, the concept of sentinel lymph node biopsy remains controversial for cutaneous squamous cell carcinoma. The aim of this study was to identify prognostic factors associated with sentinel lymph node positivity. A bicentric retrospective analysis was conducted between January 2006 and January 2018. All patients undergoing sentinel lymph node biopsy for high-risk cutaneous squamous cell carcinoma were included, based on the criteria of the prognostic classification of the French Society of Dermatology. Seventy-four patients were included. Five (6.8%) procedures failed. Of the 69 patients assessed, the positive sentinel lymph node biopsy rate was 11.6% (n = 8) with a false negative rate of 5.7% (n = 4). The positivity of sentinel lymph node biopsy was associated with tumour size (p = 0.0194). Sentinel lymph node biopsy is an effective staging procedure for clinically N0 high-risk cutaneous squamous cell carcinoma, with an acceptable morbidity. To date, 2 risk factors of sentinel lymph node positivity have been identified with statistical significance: tumour size and poor tumour differentiation.

Medical and Biotech [MESH] Definitions

A carcinoma derived from stratified squamous epithelium. It may also occur in sites where glandular or columnar epithelium is normally present. (From Stedman, 25th ed)

A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.

A mixed adenocarcinoma and squamous cell or epidermoid carcinoma.

A surgical technique used primarily in the treatment of skin neoplasms, especially basal cell or squamous cell carcinoma of the skin. This procedure is a microscopically controlled excision of cutaneous tumors either after fixation in vivo or after freezing the tissue. Serial examinations of fresh tissue specimens are most frequently done.

Unusual tumor affecting any site of the body, but most often encountered in the head and neck. Considerable debate has surrounded the histogenesis of this neoplasm; however, it is considered to be a myoblastoma of, usually, a benign nature. It affects women more often than men. When it develops beneath the epidermis or mucous membrane, it can lead to proliferation of the squamous cells and mimic squamous cell carcinoma.
