Background and objectives: Patients with in-transit melanoma metastasis have longer median survival than patients with distant metastatic disease. Furthermore, local disease control is an important endpoint for symptom management. The treatment of unresectable loco-regional recurrence or in-transit disease has been historically managed with a combination of treatments including surgery, radiotherapy, isolated limb infusion or perfusion as well as systemic therapies. Intralesional PV-10 has been used at Peter MacCallum Cancer Centre since 2010, and the current report presents a retrospective analysis of patient outcomes, reporting the response rates, durability of responses, and observed toxicities.
Methods: Records were analyzed retrieving details of 19 patients treated with PV-10 over a 4-year period from 2010 to 2014. Medical records were reviewed for these patients and data extracted.
Results: Nineteen patients with in-transit melanoma were treated with intralesional PV-10 between 2010 and 2014. Disease control (complete or partial response or disease stability) was achieved in 68% of patients with 26% having a complete response. This was achieved with minimal associated toxicity.
Conclusions: PV-10 is an effective, durable, well-tolerated treatment tool with an acceptable side effect profile for the management of unresectable in-transit melanoma. J. Surg. Oncol. 2016;114:380-384. © 2016 Wiley Periodicals, Inc.
