Patients with metastatic uveal melanoma have few therapeutic options. Chemotherapy 6, immunotherapy 23 and targeted therapy 24 have not been able to show improved OS. For patients with few liver metastases, liver resection is an option 12. Other treatments include hepatic intra-arterial chemotherapy (HIA) 9, transarterial chemoembolization (TACE) 25 and selective internal radiation therapy (SIRT) 26.

Uveal melanoma is the most common primary intraocular malignancy in adults, with the incidence being highest in Caucasian populations 1. Local treatment consists of enucleation or local plaque radiation therapy 2,3. Irrespective of local treatment, metastatic disease will ultimately develop in about 35-50% of the patients 4,5. The liver is the most common site of metastases and approximately 50% of the patients present with isolated liver metastases. The median overall survival (OS) for patients with liver metastases is 6-12 months 4. Several different systemic and regional treatment strategies have been explored, but survival rates have not improved 2.
Treatment with systemic chemotherapy, both single substance (Dacarbazine or Temozolomide6) or combination treatments (BOLD regimen7, gemcitabine with treosulfan 8), shows response rates of less then 10 %. Hepatic intra-arterial chemotherapy (HIA) has shown a slightly higher overall response rate compared to systemic chemotherapy, but no increase in overall survival 9. Transarterial chemoembolization (TACE) with cisplatin and carboplatin showed a partial response in 57% of patients with a median survival of 9 months10. Selective internal radiation therapy (SIRT) has shown a partial response in 62% of patients with a median survival of 7 months 11. In a study on liver resection, including 255 patients, an overall survival of 14 months was reported; in 76 of the patients where a microscopically complete resection was possible, the survival was 27 months 12.
Isolated hepatic perfusion (IHP) is a regional treatment option, originally developed by Ryan and Ausman. The rationale behind the technique is to surgically isolate and perfuse the liver with a high dose of a chemotherapeutic agent while avoiding systemic toxicity 13. In addition, concurrent hyperthermia mediates an increased uptake of the chemotherapeutic agent by changes in tumor blood flow and cellular membrane permeability 14. Complete vascular isolation is confirmed with a radioactive tracer technique using Tc-99 labeled human serum albumin 15. A retrospective phase II study has shown a potential survival benefit of 14 months (26 vs. 12 months) for patients that underwent IHP compared to the longest survivors with uveal melanoma liver metastases in Sweden 16.
Here we present the technique of IHP with a short review of current results and future perspectives.

isolated hepatic perfusion as a treatment for liver metastases of uveal melanoma

Isolated hepatic perfusion (IHP) is a procedure where the liver is surgically isolated and perfused with a high concentration of the chemotherapeutic agent melphalan. Briefly, the procedure starts with the setup of a percutaneous veno-venous bypass from the femoral vein to the external jugular vein. Via a laparotomy, catheters are then inserted into the proper hepatic artery and the caval vein. The portal vein and the caval vein, both supra- and infrahepatically, are then clamped. The arterial and venous catheters are connected to a heart lung machine and the liver is perfused with melphalan (1 mg/kg body weight) for 60 min. This way it is possible to locally perfuse the liver with a high dose of a chemotherapeutic agent, without leakage to the systemic circulation.
In previous studies including patients with isolated liver metastases of uveal melanoma, an overall response rate of 33-100% and a median survival between 9 and 13 months, have been reported. The aim of this protocol is to give a clear description of how to perform the procedure and to discuss IHP as a treatment option for liver metastases of uveal melanoma.

An initial report included 22 patients treated with melphalan with or without TNF-alpha. The results showed an overall response rate of 62%, including two patients with CR (10%), and a median overall survival of 11 months 20. A subsequent study reported on the outcome of 29 consecutive patients treated using melphalan alone. The outcome was very similar with a 62% overall response including 10% complete response and a median survival of 12 months 21.
