Skin cancer staging and management algorithms — Viva

Q1: Definition and systems (2 min)

Which cutaneous cancers use formal AJCC TNM staging, and how is localised BCC approached differently? Define Breslow thickness measurement.

Q2: Melanoma algorithm (3 min)

Walk through biopsy → WLE margins by thickness → SLNB threshold → MSLT-II implication of a positive sentinel node → when adjuvant/systemic therapy enters discussion.

Q3: cSCC AJCC vs BWH (3 min)

List BWH high-risk factors. How do T2b/T3 tumours change imaging and MDT behaviour compared with a small well-differentiated truncal SCC?

Q4: BCC and Mohs (2 min)

What features define high-risk BCC and when is Mohs preferred over standard excision?

Q5: Systemic options and pitfalls (2 min)

Name landmark systemic options for advanced cSCC and advanced BCC. List three staging pitfalls that change management (wrong biopsy, ignored H-zone, automatic CLND).
