T-VEC melanoma injection treatment

Would an 80 year old with a  performance level of 3/4

Melanoma stage IIIC in- transit localised in the arm no lymph nodes or liver involvement be eligible for T-VEC injection treatment .?

If the patient's local hospital does not administer T-VEC treatment could they be referred to the nearest hospital who administer it?

how is the patient assessed for treatment?
