Brief summary: In-transit metastases occur in approximately 3% of melanoma patients, can be very symptomatic and the survival in this group may be prolonged. In-transit melanoma metastases are often confined to a limb. In this circumstance, treatment by isolated limb perfusion or isolated limb infusion can be a remarkably effective regional treatment option. Isolated limb infusion (ILI) was introduced in 1992 and is a technique used to deliver regional chemotherapy to treat advanced melanoma confined to a limb. Regional chemotherapy with melphalan delivered by isolated limb perfusion (ILP) or ILI are effective treatment options for in-transit melanoma and are generally well tolerated.

ILI is a less invasive and simpler alternative to ILP. Complete response rates are 45- 69% for ILP and 23-44% for ILI. The limb is often warmed to lower temperatures in ILI compared to ILP and the limb becomes progressively more hypoxic and acidotic during ILI, each of these parameters potentially having an effect on outcome. ILP \& ILI are used primarily as palliative options when excision of in-transit metastases is unfeasible but can be used as an adjunctive procedure to surgery, for other tumour types such as merkel cell carcinoma, and can be repeated if indicated. For ILI correction of melphalan dose for ideal body weight has been shown to substantially decrease the rates of severe local toxicity while maintaining complete response rates, but overall response rate is reduced.

Response to ILI, moreover, is different in upper and lower limbs. ILI for Upper limbs disease is associated with similar complete response rates but lower toxicity than ILI for Lower limbs E disease and with different physiologic sequelae despite comparable methods. The Upper limbs appears relatively resistant to toxic effects of melphalan-based ILI as currently performed, which suggests a potential for further optimization of drug dosing for Upper limbs ILI.

Regional therapy is an excellent therapeutic modality for disease limited to a limb and furthermore serves as an excellent model for scientific investigation, both clinical and translational. In this study we want to collect data on isolated limb infusion of chemotherapy to monitor efficacy and tolerability in patients with melanoma metastases of the arm or leg that cannot be removed by surgery.

Detailed description: This is an observational study and the treatment is related to the experiences and economical availability of each center.

Study Design: Prospective observational study . Primary objective: To collect data on tumor response and progression free survival after administration of melphalan.

Secondary objectives: To collect data on survival rate, time to progression, morbidity tolerability of treatment, number of treatment required to achieve objective response and improvement of quality of life (Edmonton questionnaire)

Treatment under observation :

Patients undergo fluoroscopic placement of angiographic arterial and venous catheters into the appropriate extremity in order to infuse the drug (artery) and to stop the out flow (venous with balloon catheter). Melphalan 1mg/kgr is rapidly infused into the isolated limb via the arterial catheter after the inflation of venous balloon catheter. Then the circulation of the limb is blocked with a pneumatic cuff at the root of the limb . Patients with little or no response at 8 weeks may receive up to 2 additional treatments at the discretion of the treating physician.

Patients are followed at 1-2 weeks, 3-4 weeks, 6-8 weeks, and then every 3-6 months thereafter as deemed necessary by the treating physician.

Day -1 Melphalan 1mg/ Kgr has been prepared at Pharmacy.

Day 0: prehydration, antibiotic prophylaxis and setting up of a therapeutic scheme appropriate for analgesic prophylaxis (3-day duration) as previously reported (25)

Day +1:

Upon admittance to the radiology room, 1 vial of tropisetron (diluted in 100ml of physiological solution) administered by slow drip.

During infusion of the Melphalan into the artery, 1 vial of morphine hydrochloride diluted in 100 ml i.v. to be repeated one hour after the procedure and if necessary also after 6 hours.

Tropisetron i.v. if needed. Intra-arterial premedication with 1 vial of verapamil diluted in 4 ml of normal saline solution followed by 4 ml of lidocaine.

Intra femoral infusion of Melphalan Second ILI treatment could be repeated at side effects recovery ( following oncologist ' s planning of cure).

Day +30: The above procedure is repeated.

Day +90: In case of response, a third administration following the above procedures will be repeated.

Evaluation of response:

Response must be assessed by repeating the following examinations at Day 30, Day 90 and Day 120 after start of treatment:

Limb-Chest-abdomen CAT scan with and without contrast medium (refer to Section 4). Evaluation will be based on Response Evaluation Criteria in Solid Tumors (RECIST ) criteria \[20-24 \] cancer markers (CEA, cancer antigen (CA) 19.9)

Assessment of quality of life The Edmonton Symptom Assessment System (ESAS) is used to monitor health conditions and quality of life.

Assessment of quality of life is performed during the baseline visit and at Day 30, Day 60 and Day 120 from start of treatment.
