Melanoma Flashcards
First line management of acral melanoma
Checkpoint inhibitors
Drug approved for uveal melanoma and 2) HLA
HLA-A*02:01-positive
Tebentafusp
Size threshold for SNLB in melanoma
Greater than 0.8 mm
Dabrafenib tremetinib SE to know
Pyrexia
encobimetinib SE to know
ocular toxicity
Gene mutation associated with hereditary melanoma (familial atypical mole syndrome)
CDKN2A
p16
FAM syndrome presentation
A lot of atypical appearing moles
Other genetic syndromes associated with melanoma
BRCA2
pTEN (Cowden)
BAP1
Stage III melanoma definition
nodal mets OR *in transit metastases
Other indications for sentinel lymph node biopsy
- regression of tumor below breslow depth
- if base of tumor broadly transected on specimen (indicating tumor much thicker than actual read on path)
- presence of atypical features (melanocytic tumor of unknown potential)
TVEC mechanism + role
- oncolytic virus
- very limited role, possibly local control in elderly patient ineligible for immunotherapy
margins required in melanoma for wide local excision
IF <2mm, 1 cm margin
IF >2mm, 2 cm margin
*high yield
When adjuvant immunotherapy is indicated in stage II melanoma
high risk, so stage IIB and IIC
What are the BRAF/MEK combinations
dabrafenib/tremetinib
vemurafenib/cobimetinib
encorafenib/benimetinib
BRAF targeted therapy class effects
- QT prolongation
- increased risk of cutaneous squamous
- Keratoacanthomas
- LFT elevation
- photosensitivity
