• Any contra-indication for evaluation by whole body 18F-FDG-PET/CT or MRI.

• ≥ 18 years of age on the day of signing the informed consent.
• Histologically confirmed high risk primary cutaneous pT1b-4b melanoma High risk primary melanoma is defined in this study as the following AJCC8 T-stages:
• pT1b-3a, with a poor prognostic score on the Merlin™ test ("Merlin™ high risk");
• pT3b-4b, irrespective of their Merlin™ test result
  • Amendable to sentinel lymph node biopsy.
  • No evidence of metastatic dissemination as demonstrated by PET/CT, ultrasound of the draining lymph node basin, and clinical examination.
  • No prior exposure to systemic treatment for melanoma (adjuvant or curative).

• If a female patient is a woman of childbearing potential (WOCBP) they must agree to use highly effective contraception measures during the period of therapy, which should be continued for at least 4 months following the last dose of pembrolizumab as indicated in the SmPC. A list of highly effective contraceptive measures is included in appendix 1 All female patients with reproductive potential must have a negative pregnancy test (serum or urine) prior to enrollment and pregnancy testing should be conducted within 24h prior to the first dose of immune checkpoint inhibitors and thereafter monthly until 4 months following the last dose study treatment.
