    This study analyzed 925 lymph node biopsies, finding benign lesions in 60% and malignancies (carcinoma and lymphoma) in 40%. Patient age was the most significant factor in determining benign versus malignant lymphadenopathy.

    Area of Science:

    • Pathology
    • Oncology
    • Medical Diagnostics

    Background:

    • Lymphadenopathy diagnosis relies on biopsy analysis.
    • Understanding the prevalence of benign and malignant conditions in lymph nodes is crucial for clinical decision-making.

    Purpose of the Study:

    • To retrospectively analyze findings from isolated lymph node biopsies.
    • To determine the distribution of benign lesions, carcinoma, and lymphoma in lymph nodes.
    • To identify key factors influencing lymphadenopathy diagnosis.

    Main Methods:

    • Retrospective analysis of 925 isolated lymph node biopsies performed between 1973 and 1977.
    • Categorization of biopsy results into benign lesions, carcinoma, and lymphoma.
    • Detailed data collection on biopsy site, histological subtypes, patient age, and sex.

    Main Results:

    • Overall, 60% of biopsies revealed benign lesions, 28% showed carcinoma, and 12% indicated lymphoma.
    • Specific distributions varied by anatomical site: abdominal (63% benign, 33% carcinoma, 4% lymphoma), intrathoracic (73% benign, 26% carcinoma, 1% lymphoma), and peripheral (56% benign, 29% carcinoma, 15% lymphoma).
    • Patient age was identified as the most statistically significant factor in predicting whether lymphadenopathy was benign or malignant.

    Conclusions:

    • Lymph node biopsy analysis provides essential diagnostic information.
    • The prevalence of benign versus malignant conditions in lymph nodes differs based on anatomical location.
    • Age is a critical demographic factor for assessing the likelihood of malignancy in lymphadenopathy.
