[https://doi.org/10.1016/j.xcrm.2025.102240](https://doi.org/10.1016/j.xcrm.2025.102240)  \nSUMMARY  \nThis review addresses the integration of chimeric antigen receptor (CAR)-T cell therapy with reconstructive oncologic surgery in treating peripheral solid tumors, including melanoma, sarcomas, breast cancer, and head and neck cancers. While CAR-T cells have demonstrated effectiveness in blood cancers, their efficacy in solid tumors has been limited due to tumor heterogeneity, immune suppression, and poor cellular infiltration. Emerging approaches involving localized CAR-T cell delivery, improved CAR design, and targeted antigen selection (such as HER2, MUC1, GD2, and B7-H3) are discussed as promising strategies to enhance therapeutic outcomes. Clinical studies highlighted in this review indicate improved local tumor control and potential to optimize surgical resections. Additionally, combining CAR-T therapy with surgery may reduce tumor recurrence and positively influence reconstructive outcomes. Overall, this review underscores CAR-T cell therapy as a potential adjunctive treatment in oncologic surgery, emphasizing the importance of interdisciplinary approaches to improve patient outcomes in solid tumor management.  \nBACKGROUND  \nCancer continues to be the second most common cause of death in the US totaling 1.9 million new cases and 609,360 deaths in the US in 2022.1 About 60% of US cancer patients undergo surgical cancer treatment.2 Peripheral solid tumors (PSTs), such as breast, malignant skin, head and neck cancers, and sarcomas represent challenges for patients and providers.3 They commonly require primary resection, the therapeutic gold standard for localized stages.4–7 PST resection necessitates reconstructive surgery to support patient rehabilitation and improve postoperative quality of life.8–10 Current cancer guidelines suggest a close coordination of oncologic resect","cbCaieFVEUmi7CEH","https://ap.wps.com/l/cbCaieFVEUmi7CEH","pdf",4053380,14,"English","# Summary\n# Background\n## Cancer burden and role of surgery\n## Peripheral solid tumors and reconstruction needs\n## CAR-T cells and the challenge in solid tumors\n# CAR design evolution and mechanisms\n## First- to fourth-generation CAR constructs\n## Cytokine release and immune modulation\n## Latest-generation design directions","[{\"question\":\"Why is CAR-T cell therapy less effective in peripheral solid tumors than in blood cancers?\",\"answer\":\"Efficacy is limited by tumor heterogeneity, immune suppression, and poor CAR-T cellular infiltration into solid tumor tissue.\"},{\"question\":\"Which strategies does the review discuss to improve CAR-T performance in solid tumors?\",\"answer\":\"It highlights localized CAR-T delivery, improved CAR engineering, and targeted antigen selection such as HER2, MUC1, GD2, and B7-H3.\"},{\"question\":\"How might combining CAR-T therapy with surgery affect treatment and reconstruction outcomes?\",\"answer\":\"The review reports that combining therapy may enhance local tumor control, help optimize surgical resections, and potentially reduce recurrence while supporting reconstructive outcomes.\"}]","CAR-T cell therapy and reconstructive oncologic surgery in peripheral solid tumors - A narrative review | PDF",1790202382,35]
