    Summary
    This summary is machine-generated.

    This study analyzed lung metastases in 88 specimens, differentiating formation stages via angiography. Tumor regression and immune markers are crucial for clinical assessment of lung metastases.

    Area of Science:

    • Oncology
    • Pathology
    • Radiology

    Background:

    • Lung metastases are a significant clinical challenge.
    • Understanding metastasis formation is key to treatment.
    • Neovascularization plays a critical role in metastasis.

    Purpose of the Study:

    • To analyze the topography, size, and histopathology of lung metastases.
    • To differentiate the stages of metastasis formation (invasion, embolization, implantation).
    • To investigate the role of neovascularization in metastasis development.

    Main Methods:

    • Analysis of 88 operative specimens of lung metastases.
    • Postmortem angiography to investigate neovascularization (20-60 micron vessels).
    • Morphological quantification of tumor regression after cytostatic therapy.

  • Immune histochemical examinations for unknown primary cancer.

    • Main Results:

    • Detailed topographical, size, and histopathological data of lung metastases were obtained.
    • Angiography successfully differentiated metastasis formation stages by visualizing neo-vascularization.
    • Methods for assessing tumor regression and immune markers were validated.

    Conclusions:

    • The study provides a comprehensive analysis of lung metastasis characteristics.
    • Angiography is a valuable tool for understanding metastasis dynamics.
    • Morphological and immune analyses are clinically important for managing lung metastases, especially in unknown primary cancers.
