Alongside the main melanoma treatments, there are some less common therapies your medical team may consider in specific situations — usually when melanoma is confined to one area, or when other treatments aren’t suitable. This page explains two of them: treatment delivered directly into a limb, and a treatment injected straight into the melanoma.
Isolated limb infusion (ILI) and isolated limb perfusion (ILP)
Other treatments such as isolated limb infusion (ILI) and isolated limb perfusion (ILP) can sometimes be recommended if the melanoma is in one place, for example an arm or a leg. This treatment involves giving chemotherapy through the bloodstream of the affected limb only, so it does not circulate through the rest of your body.52
The procedure is performed by a surgeon and requires a general anaesthetic. Afterwards, patients usually stay in hospital for a few days. Your surgical team will explain exactly what your procedure involves and what to expect from your recovery.
Talimogene laherparepvec (Imlygic® or T-VEC)
Talimogene laherparepvec (Imlygic® or T-VEC) is recommended for certain types of stage 3 or 4 melanoma that have spread, cannot be removed by surgery, and are not suitable for treatment with other immunotherapy options. It is injected directly into the melanoma on the skin — usually once, then again two weeks later, and then every three weeks after that.
Your specialist will explain whether this treatment is suitable for you, how many injections you’re likely to need, and what to expect during and after treatment.
Questions to ask your doctor
- Why is this treatment being recommended for me?
- What does the procedure involve, and will I need a general anaesthetic?
- How long will I need to stay in hospital?
- How many treatments will I need?
- What side effects could I experience, and how will they be managed?
- Are there any long-term side effects?
How these fit into your treatment plan
Treatments like these are generally used in specific circumstances rather than as a first option. Whether they’re right for you depends on the stage of your melanoma and where it is in the body. Our guide to melanoma treatment by stage explains what’s usually considered at each stage, and you can read about the more common approaches on our immunotherapy, targeted therapy and surgery pages.
You’re not facing this alone
If one of these treatments has been suggested for you, it’s natural to have questions. Whatever stage you’re at, our melanoma support team and community are here to help, and you can read real patient stories from others who’ve been through treatment themselves. 💛
