The benefits of RT have been recognized for decades, and it is commonly employed in the management of both primary brain tumors and, especially, brain metastases. Through the induction of DNA damage and disruption of cellular integrity, RT promotes apoptosis and inhibits the proliferative capacity of cancer cells. Advances in imaging, dose planning, and delivery techniques have significantly enhanced the precision of RT, allowing for effective tumor eradication while minimizing harm to surrounding healthy tissue. As a result, RT improves local disease control and contributes to prolonged survival in patients with brain tumors. Nonetheless, intracranial RT may inadvertently damage surrounding healthy brain structures. The effects of RT can manifest as both acute and delayed toxicities, potentially compromising patient quality of life and long-term outcomes. For treating clinicians, a thorough understanding of these complications is necessary to design radiation treatment plans that properly balance the therapeutic efficacy of therapy with the risks of adverse treatment-related outcomes. In this review, we explore the distinct pathophysiological mechanisms, symptoms, and management strategies associated with acute, early delayed (one to six months), and late delayed radiation-induced brain toxicities. In particular, we discuss the risks of somnolence syndrome, peri-ictal pseudoprogression, radiation necrosis, vascular disorders, cognitive impairment, cranial neuropathies, endocrine dysfunction, the development of secondary malignancies, stroke-like migraine attacks after radiation therapy (SMART) syndrome, and acute late-onset encephalopathy after radiation therapy (ALERT) syndrome after brain RT.</p>","PeriodicalId":9945,"journal":{"name":"Chinese clinical oncology","volume":"14 3","pages":"32"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144504971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach has demonstrably improved cosmetic outcomes and health-related quality of life metrics for patients undergoing oncological intervention. The progression of surgical methodology from Halsted's radical mastectomy to contemporary oncoplastic techniques constitutes a fundamental paradigm shift in surgical approach. Meta-analyses and prospective cohort studies have established that oncoplastic techniques maintain oncological safety when compared with conventional BCS and mastectomy, demonstrating comparable local recurrence (LR) rates and disease-free survival (DFS) outcomes. Multiple classification systems for oncoplastic procedures have been established based on quantifiable metrics including percentage of breast volume resected, surgical complexity indices, and technical approach parameters, providing evidence-based frameworks for clinical decision-making. The breast surgeon currently functions as the critical nexus in multidisciplinary treatment of BC, integrating optimized surgical techniques with multimodal treatment protocols, particularly systemic therapeutic agents. The implementation of neoadjuvant chemotherapy (NCT) regimens has expanded the indications for breast conservation in cases previously requiring mastectomy, leading to the development of the \"extreme oncoplasty\" concept for selected patients. Nevertheless, significant implementation barriers persist globally, predominantly related to educational infrastructure limitations and the absence of standardized oncoplastic surgical training curricula for breast surgeons. Diverse training methodologies have emerged internationally, including simulation-based learning, subspecialty fellowships, and curricular integration in surgical residency programs, though outcome-based standardization remains elusive. This non-systematic review analyzes the developmental trajectory of breast cancer surgery, examining the evolution and validation of oncoplastic techniques, standardized classification systems, applications in challenging clinical scenarios, and the current status of surgical education, emphasizing the pivotal role of professional societies in developing evidence-based educational initiatives to broaden access to these advanced surgical techniques.</p>","PeriodicalId":9945,"journal":{"name":"Chinese clinical oncology","volume":"14 2","pages":"20"},"PeriodicalIF":2.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143974536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
