[Metastasizing bronchial carcinoids].

    Voprosy Onkologii
    |January 1, 1978

    Summary
    This summary is machine-generated.

    Bronchial carcinoids metastasize in about 22% of cases, regardless of anatomical form. Histological and cytologic atypism influence secondary lung changes, not metastasis risk.

    Area of Science:

    • Oncology
    • Pulmonary Medicine
    • Pathology

    Context:

    • Bronchial carcinoids are neuroendocrine tumors of the lung.
    • Metastasis is a significant concern in carcinoid tumor progression.
    • Understanding factors influencing metastasis is crucial for patient outcomes.

    Purpose:

    • To investigate the incidence and patterns of metastasis in bronchial carcinoids.
    • To correlate histological and cytologic features with metastatic potential.
    • To examine the relationship between tumor characteristics and secondary lung changes.

    Summary:

    • Bronchial carcinoids metastasize in approximately 22% of cases, irrespective of their anatomical growth form.
    • Metastases can occur with various histological structures, including typical and atypical patterns with or without cell atypism.

  • Secondary lung changes are dependent on tumor localization and anatomical form, not directly on histological structure.
  • Secretory granules are typically absent in tumor cells, even in cases with carcinoid syndrome, when using Fontana silverring and diazol rose staining.

    • Impact:

    • Provides insights into the metastatic behavior of bronchial carcinoids.
    • Aids in refining prognostic assessments based on histological and cytologic evaluation.
    • Informs clinical management strategies by highlighting factors associated with secondary lung pathology.
