When to Use

The Brigham and Women's Hospital (BWH) staging system is used to risk-stratify primary cutaneous squamous cell carcinoma (cSCC) for nodal metastasis and disease-specific death. It was developed as a clinically superior alternative to the AJCC 7th edition (and validated against the 8th edition), specifically addressing the failure of AJCC T2 to discriminate between low- and high-risk tumors. It is particularly valuable for identifying the small subset of cSCC (BWH T2b/T3) that carries disproportionate metastatic risk.

Indications

All primary invasive cutaneous SCC following pathological diagnosis

Risk stratification before determining need for nodal staging (ultrasound, SLNB)

Determining eligibility for adjuvant radiation therapy discussion

Multidisciplinary tumor board stratification for high-risk cSCC

Prognostic counseling in immunocompromised patients (transplant, CLL, HIV)

When NOT to Use

SCC of the lip or ear — these sites have distinct prognostic data and some guidelines use AJCC head/neck staging

SCC in situ (Bowen's disease) — not invasive; not applicable

Mucosal SCC (oral, anogenital, conjunctival) — separate staging systems apply

Merkel cell carcinoma — completely separate staging

Related Scores in Practice

In clinical practice, this assessment is frequently evaluated alongside other validated measures. Depending on the patient's presentation and specific diagnostic requirements, you may also need to utilize the Breslow & Clark Microstaging, AJCC Melanoma Staging or the Seven Point Dermoscopy to formulate a comprehensive care plan.
