Intravenous leiomyomatosis (IVL) is a rare benign smooth muscle tumor originating from the uterus and characterized by intravascular growth along the venous system, with potential extension to the inferior vena cava, right heart, or pulmonary arteries, leading to life‐threatening cardiorespiratory complications. IVL carries a 10%–31% recurrence rate and exhibits quasimalignant biological behavior despite its benign histology. Surgical resection is the main treatment. Current studies on IVL remain limited with regard to molecular and genetic mechanisms. This review systematically summarizes the research progress on IVL from the perspectives of chromosomal aberrations, copy number variations, gene mutations, transcriptomics, proteomics, histopathology, and epigenetic alterations. In addition, IVL is compared with uterine leiomyoma, leiomyosarcoma, and benign metastasizing leiomyoma to clarify its similarities and differences. This review also discusses unresolved issues, including tumor origin, intravascular invasive mechanisms and recurrence biomarkers, as well as prospects for future directions. A comprehensive understanding of the genetic and molecular features of IVL will help elucidate its pathogenesis, improve differential diagnosis and clinical management, and provide a theoretical basis for targeted therapy.

Gastrointestinal stromal tumors (GISTs), the most prevalent mesenchymal neoplasms of the gastrointestinal tract, frequently metastasize to the liver. Despite this clinical reality, there is a lack of standardized therapeutic protocols for GIST liver metastases (GISTLM). Here we present the first case of a GISTLM patient treated with Yttrium‐90 (Y90) resin microsphere selective internal radiation therapy (SIRT) in China. We further reviewed the current challenges in GISTLM management and highlighted the emerging role of SIRT. By integrating case‐specific insights with broader therapeutic paradigms, we aim to develop safe and effective individualized treatment strategies for GIST patients.

Liquid–liquid phase separation (LLPS) has emerged as a pivotal biological phenomenon involved in various cellular processes, including the formation of membrane‐less organelles and the regulation of biomolecular condensates through precise spatiotemporal coordination of signaling pathways in cells. Dysregulation of LLPSs results in aberrant biomolecular condensates, which are widely implicated in tumorigenesis and cancer progression. Here, we comprehensively summarize the multifaceted roles of LLPS in tumor biology from the perspective of cancer hallmarks, including genomic stability, metabolic reprogramming progression, ferroptosis, and metastasis, to unveil the intricate mechanisms by which LLPS occurs in tumorigenesis. We discuss current discoveries related to therapeutic involvement and potential clinical applications of LLPS in cancer treatment, highlighting the potential of targeting LLPS‐driven processes as novel therapeutic strategies. Additionally, we discuss the challenges associated with new approaches for cancer treatment based on LLPS. This in‐depth discussion of the impact of LLPS on fundamental aspects of tumor biology provides new insights into overcoming cancer.

von Hippel‐Lindau (VHL) disease is a rare autosomal dominant multiorgan disease characterized by several benign and malignant tumors rich in vascular, as well as cysts in other organs. A great clinical treatment strategy is significantly warranted for good prognosis of patients with VHL disease. Herein, we reported a case of a 45‐year‐old woman diagnosed with VHL disease with spinal hemangioblastoma (HB) and clear cell renal cell carcinoma (ccRCC). Four years after the resection of the right kidney, a recurrent RCC in the right kidney and a malignant lesion in the left kidney were observed. This patient was started on sorafenib (800 mg, daily) and tislelizumab (200 mg per 3 weeks). After 6 months of treatment, the size of renal cell carcinoma was dramatically reduced and renal function improved. More importantly, she achieved partial response during the whole treatment. Microscopically, intramedullary masses resection was done and the HB in T4‐5 thoracic spinal was removed. Neurologic symptoms such as numbness and pain were remarkably alleviated. Additionally, tislelizumab‐induced elevation in liver transaminase levels and hypothyroidism were revered by hepatoprotector and levothyroxine, respectively. In short, comprehensive treatment strategies may benefit patients with VHL disease, especially with HB and ccRCC.

The phenomenon of tumor hierarchy and genetic instability can be explained by the “two‐hits theory” and results in the occurrence of many somatic mutations. The expression of nonsynonymous mutations results in the production of mutant proteins from tumor cells, namely tumor‐specific antigens called neoantigens. Because neoantigens do not exist in healthy cells, they have the potential to stimulate antitumor immune responses by CD4+ and CD8+ T‐cell activation without jeopardizing normal tissues. Immunotherapy has reshaped the cancer treatment paradigm in recent decades with the introduction of immune‐checkpoint blockade therapy and transgenic T‐cell receptor/chimeric antigen receptor T cells. However, these strategies performed poorly in solid tumors because of the obstacles of the immunosuppressive microenvironment caused by regulatory T cells and other suppressor cells. Therefore, other immunotherapeutic strategies are under development, such as personalized vaccines, to trigger de novo T‐cell responses against neoantigens and lead to the amplification of tumor‐specific T‐cell subclones. Neoantigen epitope prediction algorithms have enabled the detection of neoantigens and the creation of tailored neoantigen vaccines as a result of the fast development of next‐generation sequencing and cancer bioinformatics. Here we provide an overview of the current neoantigen cancer vaccines and adoptive T‐cell transfer therapy with neoantigen‐specific lymphocytes. We also discuss the challenges in developing neoantigen‐targeted immunotherapeutic strategies for cancer.
