The use of immunocytochemical study in the cytologic diagnosis of melanoma: evaluation of three antibodies. Circulating melanoma cells (CMCs) have been detected in blood by qPCR of melanocyte specific genes or by enrichment using melanocyte surface markers; CMCs have shown prognostic value in identifying disease stage [112], progression [113, 114] and overall survival [115] but, sensitivity of CMC detection is low (reviewed in [115, 116]). Epub 2011 Nov 21. 2011;13:423–33. Therefore, patients with tumors that are positive for this BRAF mutation may have improved survival with treatment due to this new treatment. Urinal biomarker for the diagnosis of melanoma 2.4 Biomarkers for early melanoma diagnosis The early diagnosis of melanoma is closely relate d to an increase in survival rate. Whole blood contains different inflammatory and immune cell subsets such as peripheral blood mononuclear cells (PBMCs), and can also contain circulating tumor cells (CTCs), derived from malignant cells that have detached from primary or metastatic tumor sites and shed into the circulation.

Both MAPK and immune checkpoint inhibitor therapies have significant limitations, however. 1998;11(8):740–746. Nevertheless, the precise mechanism of ctDNA release remains to be determined and may potentially include tumor cell necrosis, secretion from metabolically active tumor cells, or phagocytosis of necrotic tumor cells by macrophages [53]. In this era of effective molecular targeted treatments and immunotherapies, there is now an urgent need to implement use of these circulating biomarkers in the clinic to facilitate personalized therapy.
