RT Journal Article SR Electronic T1 COX-2 as a potential biomarker and therapeutic target in melanoma JF Cancer Biology and Medicine JO Cancer Biol Med FD China Anti-Cancer Association SP 20 OP 31 DO 10.20892/j.issn.2095-3941.2019.0339 VO 17 IS 1 A1 Diana Valentina Tudor A1 Ioana Bâldea A1 Mihai Lupu A1 Teodor Kacso A1 Eniko Kutasi A1 Andreea Hopârtean A1 Roland Stretea A1 Adriana Gabriela Filip YR 2020 UL http://www.cancerbiomed.org/content/17/1/20.abstract AB With a constantly increasing incidence, cutaneous melanoma has raised the need for a better understanding of its complex microenvironment that may further guide therapeutic options. Melanoma is a model tumor in immuno-oncology. Inflammation represents an important hallmark of cancer capable of inducing and sustaining tumor development. The inflammatory process also orchestrates the adaptative immunosuppression of tumor cells that helps them to evade immune destruction. Besides its role in proliferation, angiogenesis, and apoptosis, cyclooxygenase-2 (COX-2) is a well-known promoter of immune suppression in melanoma. COX-2 inhibitors are closely involved in this condition. This review attempts to answer two controversial questions: is COX-2 a valuable prognostic factor? Among all COX-2 inhibitors, is celecoxib a suitable adjuvant in melanoma therapy?
