Email [ramon.yarza@salud.madrid.org](ramon.yarza@salud.madrid.org)  \nAbstract  \nBackground: T-cell receptor (TCR-T) therapies are based on the expression of an introduced TCR targeting a tumor associated antigen (TAA) which has been studied in several trials in cutaneous melanoma. We conducted a systematic review and meta-analysis aiming to assess the primary efficacy ofTCR-based adoptive cell therapy in cutaneous melanoma.  \nMethods: We searched through PubMed electronic database from its inception until May 21, 2022. Primary endpoints were pooled objective response rate (ORR) and disease control rate (DCR) . We conducted logistic regression analyses to identify potential predictive factors for tumor response.  \nResults: From 187 patients, 50 showed an objective response (pooled ORR 28%; 95% CI, 20%-37%) and a pooled DCR of 38%(95% CI, 27%-50%) . Median PFS was 2, 9 months (95% CI, 1.4-3. 1) . A trend toward higher PFS was demonstrated for patients treated with cancer/testis antigens targeting TCR-T cells (HR 0.91 95% CI, 0.64-1.3, P = .61) among whom, patients treated with NYESO-1 targeting TCR-T showed a significantly higher PFS (HR 0.63 95% CI, 0.64-0.98, P = .03) . In addition, the number of infused cells was associated with a significantly higher likelihood of tumor response (OR 6.61; 95% CI, 1.68-21.6; P = .007) .  \nConclusion: TCR-T therapy shows promising results in terms of antitumor activity and survival similar to those reported forTILs with a significantly higher benefit for cancer/testis antigens targeting cells. Since TCR-based therapy shows advantages of great potential over classic ACT strategies, further research in solid cancers is warranted (PROSPERO ID CRD42022328011) .  \nKey words: adoptive cell therapy; T-cell receptor; cutaneous melanoma; meta-analysis.  \nAbbreviations: ACT, adoptive cell therapy; CAR, chimeric antigen receptor; CAR-T, chimeric antigen receptor T cell; CR, complete response; DC, dendritic cell; DCR, disease control rate; DoR, duration of response; DoS, duration of stability; FEM, fixed effect model; gp100, glycoprotein 100; HD, high-dose; HLA, human leukocyte antigen; HR, hazard ratio; ICB, immune checkpoint blockade; iCTLA-4, cytotoxic T-lymphocyte associated protein 4 inhibitor; IL2, interleukin 2; iPD1, programmed death 1 inhibitor; LD, low-dose; MAGE-A3, melanoma-associated antigen 3; MART1, melan-A; melanoma antigen recognized by T cells; MHC, major histocompatibility complex; NMA, non-myeloablative; NYESO-1, New York esophageal squamous cell carcinoma 1; OR, odds ratio; ORR, objective response rate; OS, overall survival; PD, progression disease; PFS, progression-free survival; PR, partial response; REM, random effect model; scFv, single chain variable fraction; SD, stable disease; SMAC, supramolecular activation cluster; TAA, tumor associated antigen; TCR, T-cell receptor; TCR-T, T-cell receptor T cell; TIL, tumor-infiltrating lymphocyte  \nImplications for Practice  \nAdoptive cell therapy aims to target cancer cells by genetically engineered immune cells with the objective of enhancing tumor recognition and effective tumor killing. We demonstrate that TCR-T-based ACT has similar efficacy results compared to those reported forTILs among heavily pretreated melanoma patients.
