Surgery remains the first-line treatment for early-stage tumors but is often not an option for advanced-stage melanoma. Chemotherapy carries a poor prognosis, and despite advances in targeted therapy, the cancer can develop resistance. CAR Tcell therapy has demonstrated great success against hematological cancers, and clinical trials are deploying it against advanced melanoma. Though melanoma remains a challenging disease to treat, radiology will play an increasing role in monitoring both the CAR T-cells and response to therapy. We review the current imaging techniques for advanced melanoma, as well as novel PET tracers and radiomics, in order to guide CAR T-cell therapy and manage potential adverse events.  \nKeywords: melanoma; CAR T-cell; metastases; radiomics; PET radiotracers; CAR T-cell imaging; radiology; CAR T-cell toxicity  \n1. Introduction  \nWorldwide, incidences of melanoma have been increasing faster than nearly all other cancers across all age groups. Typically, primary melanoma is detected through physical and dermatological examination; however, it is a notoriously aggressive cancer (the deadliest form of skin cancer), and its metastases can invade nearly every organ system and carry a poor prognosis. Therefore, radiology plays an increasingly valuable role in detecting, prognosticating, and managing later stages of the disease. We will provide the most comprehensive review thus far of medical imaging's current and future role in advanced melanoma and discuss its expected role in guiding and monitoring CAR T-cell treatment for this disease.  \n1.1. Clinical Setting of Melanoma  \nAs with most skin cancers, the main risk factor for melanoma is ultraviolet radiation exposure. Exposure to ultraviolet rays causes DNA damage to cells, which leads to cellcycle arrest and apoptosis in normal cells, or abnormal proliferation and further mutation in cancer cells. Melanoma is currently ranked the sixth most common fatal cancer in the United States; this is expected to rise as population densities increase near the equator and with more frequent use of indoor tanning beds and outdoor activities. Fortunately, as for other skin cancers, the risk for melanoma can be easily lowered by minimizing time in the sun, avoiding exposure during peak hours, and applying sunscreen.  \nEarly-stage melanoma can be treated ","cbCaiuMT9rVbLQsK","https://ap.wps.com/l/cbCaiuMT9rVbLQsK","pdf",8469081,"English","# Introduction\n## Clinical Setting of Melanoma\n## Current Limitations of Therapies for Advanced Melanoma","[{\"question\":\"Why is imaging increasingly important in advanced melanoma?\",\"answer\":\"Imaging supports detection, prognostication, and management as melanoma metastasizes across many organ systems, especially in later stages where treatment options expand beyond surgery.\"},{\"question\":\"What role does radiology play in CAR T-cell therapy for advanced melanoma?\",\"answer\":\"Radiology is expected to monitor CAR T-cells and assess response to therapy, helping guide treatment decisions and manage potential adverse events.\"},{\"question\":\"Which advanced melanoma therapies are discussed as having limitations prior to newer approaches?\",\"answer\":\"Before immunotherapy and targeted therapy, melanoma was treated using surgery and chemotherapy, and metastatic disease had poor surgical outcomes and dismal survival rates.\"}]","More than Just Skin-Deep: A Review of Imaging's Role in Guiding CAR T-Cell Therapy for Advanced Melanoma | PDF",1790226434]
