    Area of Science:

    • Oncology
    • Pathology
    • Molecular Biology

    Background:

    • Olfactory neuroblastomas (ONBs) are rare malignancies originating from olfactory receptor cells in the nasal cavity.
    • Accurate diagnosis is challenging, particularly for poorly differentiated tumors, impacting clinical outcomes and treatment strategies.
    • Standardization of diagnosis, treatment, and outcome prediction remains difficult due to limited large-scale studies.

    Purpose of the Study:

    • To review the current knowledge on the histopathological diagnosis of olfactory neuroblastomas.
    • To summarize the molecular biology of these tumors.
    • To outline the current management strategies and challenges in treating olfactory neuroblastomas.

    Main Methods:

    • Literature review of histopathological diagnostic criteria for olfactory neuroblastomas.
    • Analysis of molecular and immunohistochemical markers relevant to ONB classification.
    • Synthesis of current treatment guidelines, including surgical and radiotherapeutic approaches.

    Main Results:

    • Diagnostic challenges exist, especially with poorly differentiated tumors, highlighting the need for molecular and immunohistochemical markers.
    • Endoscopic surgical resection combined with postoperative irradiation is the primary treatment modality.
    • Elective neck irradiation is recommended to reduce the risk of nodal recurrence.

    Conclusions:

    • Molecular characterization is essential for precise diagnosis and identifying therapeutic targets for personalized medicine.
    • Standardized diagnostic and treatment protocols are needed to improve patient outcomes for olfactory neuroblastomas.
    • Further research and large-scale studies are required to advance the management of this rare cancer.
