Pharmacotherapy of regional melanoma therapy.

IMPORTANCE OF THE FIELD

In-transit melanoma metastases develop within regional dermal and subdermal lymphatics before reaching the regional lymph nodes. The prognosis is poor and comparable to multiple nodal metastases. Isolated limb infusion (ILI) or perfusion (ILP) are effective treatments for unresectable, in-transit melanoma, with response rates reaching 95%. Although ILI and ILP are more effective than systemic therapy, most patients will recur, thus highlighting the need for newer strategies to improve durable response rates.

AREAS COVERED IN THIS REVIEW

We review historical and current literature from 1958 to 2009 regarding regional therapy for melanoma, with focus on the ILI and ILP techniques, pharmacokinetics and resistance mechanisms of melphalan. Alternative therapies, adjunct strategies and new targeted therapies aimed at improving response rates and long-term remission are also discussed.

WHAT THE READER WILL GAIN

The reader will gain a comprehensive review on regional pharmacotherapy for melanoma, including alternative therapies, adjunct strategies and new targeted therapies.

TAKE HOME MESSAGE

Regional chemotherapy is a viable, evolving treatment for patients with in-transit melanoma and a springboard for ongoing research aimed at improving therapies for malignant melanoma.
