Although the tumor-node-metastasis (TNM) staging system and single-parameter assessments such as tumor budding, T-cell density, tertiary lymphoid structures (TLS), and stromal features provide important prognostic information, they capture only partial aspects of this spatially organized tumor-host interface. Inspired by the traditional Chinese medicine concept of \"Huchang\", used here as a metaphorical descriptor of host-protective organization at the tumor boundary, and informed by recent advances in spatial immunology, we propose the Huchang-Barrier (HB) framework. HB conceptualizes the invasive front as a dynamic tumor-host interface whose biological state is determined by the balance between tumor invasive burden and host physical/tissue and spatial immune barriers. Unlike fixed single-marker scores or tumor-type-specific microenvironmental indices, HB integrates three conserved functional elements while allowing cancer-adapted readouts, thereby providing a modular framework for evaluating the invasion-barrier balance at the invasive front. To improve operability, we outline a two-tier assessment strategy and provide a minimal executable HB-Standard example in resected non-small cell lung cancer (NSCLC). The HB framework is proposed as a hypothesis-generating spatial pathology model that requires retrospective calibration, independent validation, and prospective testing before clinical implementation.</p>","PeriodicalId":74151,"journal":{"name":"Medical review (Berlin, Germany)","volume":"6 4","pages":"354-358"},"PeriodicalIF":0.0,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13526689/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148868185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, emerging multi-omics and microenvironment evidence challenges this paradigm. Advanced tumors transcend cellular abnormality to form a \"neoorgan\" - a complex tissue ecosystem with multicellular coordination, functional autonomy, metabolic symbiosis, neural integration, and evolutionary potential. Genomic instability generates lineage-specific karyotypes; tumors reactivate ancient gene modules from primitive multicellular organisms; they actively remodel immune function via mitochondrial transfer; and they establish functional connections with the nervous system. Based on this evolutionary trajectory, we propose testable predictions: tumors may progress from a parasitic neoorgan toward an independent species, as exemplified by naturally occurring transmissible tumors and the \"tumor-derived animal\" hypothesis. Recognizing cancer as an evolutionary entity striving for independence - rather than a mere genetic malfunction - demands a fundamental shift in therapeutic strategy. Instead of solely cytotoxic \"killing\", rational approaches may aim to reintegrate the tumor into host regulatory networks or guide its evolution toward self-destruction.

However, accumulating evidence indicates that BMT represents a far more profound biological process: an enforced collapse and subsequent reconstruction of the hematopoietic and immune system. This process provides a unique human model to investigate how immune homeostasis can be reprogrammed beyond physiological conditions. Importantly, post-transplant immunity does not revert to a pre-existing state but instead converges on a newly defined equilibrium shaped by conditioning-induced injury, donor-recipient immune interactions, stromal regeneration, and therapeutic interventions. In this review, we conceptualize BMT as an immune reset and synthesize emerging insights into the mechanisms that govern tolerance reinstallation and immune stability after transplantation. By reframing BMT as a model of immune reset rather than simple immune reconstitution, we highlight general principles of immune homeostasis restoration that extend beyond transplantation and may inform therapeutic strategies for autoimmunity, immune aging, and immune-mediated diseases.</p>","PeriodicalId":74151,"journal":{"name":"Medical review (Berlin, Germany)","volume":"6 4","pages":"273-286"},"PeriodicalIF":0.0,"publicationDate":"2026-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13526690/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148868242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We summarize barrier organization, the renewal and repair mechanism to maintain the epithelial integrity under persistent exposure. We then integrate factors shaping barrier steady state, including diet, microbial metabolites, host factors and drugs. Next, we explained how barrier-regulated signal outputs disseminate through immune inflammatory mediators, neural pathways and endocrine metabolic signals, and analyzed how reverse regulation by the brain, liver, lungs and systemic metabolic state reshapes barrier responses. In neuropsychiatric, hepatic, pulmonary, and endocrine metabolic diseases, we focus on the positive feedback cycle, heterogeneity, and the ambiguity in causal direction, and evaluate treatment strategies, covering dietary intervention, microbiota-directed therapies including fecal microbiota transplantation (FMT), and pharmacologic or immunologic methods.
