[1,2] . More than 80% of cases occur in developed countries and melanoma forms the sixth most common cancer in the developed world. The incidence of melanoma has witnessed an upward trend in the last five decades and the number of new cases diagnosed annually is increasing faster than for any other cancer in most of the developed countries [3] . The mainstay of management of melanoma is essentially early detection and surgical excision, and five-year survival rates of >90% and 80% for stage I and II lesions, respectively, have been reported. The chances for cure for locoregionally advanced and metastatic disease decrease drastically, with a survival of 50% for Stage III patients while Stage IV patients historically had a median survival of about 8-9 months and a three-year overall survival rate of about less than 15% [4,5] . Systemic treatment with a definitive survival benefit appeared to be a remote possibility traditionally. There has been recently established data which indicates an encouraging therapeutic response for metastatic melanoma with the evolution of several heterogeneous novel agents, and there is a hope for better overall survival for such patients, most of whom were deemed unfit for any curative systemic therapy until recently [6] .Traditionally, the systemic treatment for metastatic melanoma was characterized by low response rates and significant toxicities. One such agent was dacarbazine, which used to yield a response rate of about 20% and median response of a duration of about six months without any benefit in overall survival. Another such agent was high-dose interleukin (IL)-2, which provided about 6%-16% response rate and a progression-free survival of about 13 months. Interferon (IFN)-α was approved as the first agent in the adjuvant setting for selected high-risk resected cases and resulted in significant improvement in diseasefree survival (DFS) and in some prospective randomized trials, with a benefit on overall survival in some studies; however, its use was associated with significant toxicity. Temozolomide is an oral alkylator with a cytotoxic effect identical to dacarbazine. Unlike the later drug, temozolomide is administered easily through oral route and it crosses the blood-brain barrier, thus exhibiting cytotoxic effect on brain metastases. Combination chemotherapy has also been tested in several studies, without showing any improvement in response rates [7,8] .Immunotherapy for advanced and metastatic melanoma has been extensively evaluated in the recent years, and Suhag V and Vats P
