*comment: margins are not inviolate and may be modified by proximity to critical structures with attention to lymphatic drainage patterns
**comment: Mohs surgery may be considered for melanoma with lentigo maligna extending beyond the 1 margin encompassing melanoma
#comment: consider nodal basin US prior to SLNB for melanoma patients with equivocal regional LN physical exam. Nodal basin US is NOT a substitute for SLNB.
_________
Follow-up:
Modify significantly according to prognosis
- Avoidance of sun exposure
- Surveillance for Stage IIB-IV as per NCCN Guidelines (ref Swetter et al. 2021)
- All melanoma patients: Skin examination and surveillance at least once a year for life is recommended
- H&P:
- every 3-6 months x 2 years then,
- every 3-12 months x 3 years then,
- as clinically indicated
- Routine blood tests are not recommended
- Imaging:
- As indicated to investigate specific signs/symptoms
- Consider every 3-12 months x 2 years then, every 6-12 months x 3 years to screen for recurrence or metastatic disease
- Routine imaging to screen for asymptomatic recurrence or metastatic disease is NOT recommended after 3-5 years, depending on risk of relapse
- All patients with melanoma treated for cure should have at least yearly follow-up with dermatology to permit total-body surveillance.
