Abstract
Purpose: With the recent developments in novel molecular targeted therapy such as immune-checkpoint blockades, serine/threonine-protein kinase B-Raf, and mitogen-activated protein kinase kinase inhibitors, the prognosis of advanced malignant melanoma has been improving. 5-S-cysteinyl-dopa (5-S-CD), a precursor of pheomelanin, has been previously revealed to be a useful biomarker for advanced-stage malignant melanoma, especially in patients with distant metastases. Here, we aimed to assess and compare the utility of serum 5-S-CD and lactate dehydrogenase levels as markers for predicting the effects of nivolumab in advanced malignant melanoma. Methods: Baseline serum 5-S-CD and lactate dehydrogenase levels in patients with unresectable stage IIIC and IV malignant melanoma treated with nivolumab ( n = 21) were analyzed to determine their utility as predictive markers for survival. We also analyzed the prognostic value of these markers among patients with only stage IV malignant melanoma ( n = 17). Results: Our analysis showed that patients with baseline serum 5-S-CD levels >25.0 nmol/L had significantly poor prognosis. In contrast, serum lactate dehydrogenase levels at the upper limit of the normal range did not exhibit such changes. Conclusions: Serum 5-S-CD levels have the potential to be an excellent predictive marker for the efficacy of nivolumab therapy in patients with advanced malignant melanoma.

Abstract
With the recent development of novel molecular targeted drugs for advanced stage malignant melanoma (MM), including RAF and mitogen-activated protein kinase kinase inhibitors and immune checkpoint blockers, the early detection of relapse is important for managing patients with MM. In this study, we retrospectively analyzed two conventional serum biomarkers, 5-S-cysteinyl-dopa and lactate dehydrogenase, in patients with MM (n = 140) who were treated at a single Japanese institute from June 2007 to June 2015. At the initial hospital visit, serum 5-S-cysteinyl-dopa levels were significantly increased in patients with stages III (n = 38) and IV (n = 20) MM compared with patients with stages 0-II (n = 62) MM. In addition, in patients with stages III and IV MM, serum 5-S-cysteinyl-dopa levels of more than 15.0 nmol/L at initial hospital visit correlated with a poor prognosis. In 11 of 14 patients whose disease progressed during follow up (mostly from stages III-IV), serum 5-S-cysteinyl-dopa levels exceeded the normal limit of 10.0 nmol/L during the clinical detection of distant metastases. These results indicate the usefulness of measuring serum 5-S-cysteinyl-dopa levels at initial hospital visit and during follow up for early and effective therapeutic interventions using newly developed molecular targeted drugs.

Abstract
A patient who was receiving hemodialysis treatment developed melanotic macules on the surface of the penis in 2002 and showed a tumor-like mass in the same region in July 2006. The patient presented with a pedunculated tumor of 3 cm in diameter on the right side of his penis. The tumor was resected for biopsy and was diagnosed as malignant melanoma. The melanoma was in stage IIIB with pT4 N1 M0. The patient received interferon-beta for a total of three courses. A computed tomography scan in the 10th postoperative month did not find any additional metastatic foci or recurrence of the tumor. In the present case, side effects caused by interferon were not observed. Therefore, particularly in dialysis patients, immune therapy might be favored over anticancer drug treatment.
