Explanation: According to the AJCC 8th edition, primary melanoma tumor thickness is to be measured to the nearest 0.1 mm, not to the nearest 0.01 as specified in prior editions.

Explanation: According to current guidelines, tumor thickness (as determined by the AJCC criteria) and SNLB are the standards in melanoma risk stratification. In addition, gene expression profiling can provide prognostic information that can aid standard clinical and pathological staging

Explanation: According to the NCCN guidelines, wide excision is recommended for in situ melanomas; SLN biopsy is recommended for local melanoma, and systemic therapy is recommended in later stages or metastatic melanoma.

Explanation: According to the latest consensus statement on the adverse events of cancer immunotherapy, immune-checkpoint therapy can have serious immediate dermatologic adverse events, including (but not limited to) dermatitis, bullous dermatoses, and vitiligo

Explanation: In patients with early melanoma or when melanoma is suspected, studies have shown that using gene expression assays is an efficacious method for non-invasive risk stratification. As such, before offering further imaging or SNLB testing, a non-invasive test can help in deciding which patients are appropriate candidates for further diagnostic or prognostic standard of care testing.
