Abstract
Adoptive cell therapy with tumor-infiltrating lymphocytes (TILs) was recently approved for patients with advanced melanoma (metastatic or unresectable) previously treated with immune checkpoint inhibitors and BRAF/MEK targeted therapies (where appropriate). Tumor-infiltrating lymphocytes isolated from patient-derived tumor tissues enter the tumor microenvironment and recognize tumor-specific antigens, leading to the destruction of tumor cells. The multistep TIL cell therapy journey is led by a multidisciplinary health care team. Patients selected for TIL cell therapy undergo tumor tissue procurement for TIL generation, followed by preparative lymphodepletion before receiving a single-dose infusion of TIL and a short course of high-dose interleukin-2. Successful implementation of TIL cell therapy requires well-established procedures and workflows to select and screen patients, procure tumor tissue, administer TIL cell therapy, and monitor patients during treatment and after discharge. The advanced practice provider plays a central role in a patient's TIL treatment journey by planning and coordinating care across the health-care system, educating patients and staff, and providing direct and supportive patient care. Here, we review the treatment landscape for advanced melanoma and clinical data supporting TIL cell therapy. We also provide guidance related to patient selection, tumor tissue procurement, TIL cell therapy regimen, safety monitoring, symptom management, and post-discharge follow-up.
