Gastric carcinoma. A pathobiological classification

S C Ming

    Cancer
    |June 1, 1977

    Summary

    Gastric carcinomas can be classified into two distinct types: expanding and infiltrative. This classification aids in understanding their pathological features, origins, and patient outcomes.

    Area of Science:

    • Oncology
    • Pathology
    • Gastroenterology

    Background:

    • Gastric carcinomas exhibit diverse pathological features.
    • Understanding these features is crucial for diagnosis and treatment.

    Purpose of the Study:

    • To classify gastric carcinomas based on growth and invasiveness patterns.
    • To explore the implications of this classification on histogenesis, patient demographics, and survival rates.

    Main Methods:

    • Histological examination of gastric carcinoma samples.
    • Classification based on growth patterns (expanding vs. infiltrative) and cell maturation.
    • Analysis of gross appearance, histogenetic origins, and epidemiological data.

    Main Results:

    • Two main types identified: expanding (growth en masse, discrete nodules) and infiltrative (individual cell invasion).
    • Expanding type shows more glands and is associated with intestinal metaplasia.
    • Differences observed in patient age, sex, survival rates, and epidemiological distribution between the two types.

    Conclusions:

    • A simple histological classification of gastric carcinoma into expanding and infiltrative types is proposed.
    • This classification provides a basis for evaluating various aspects of gastric cancer, including its origins and clinical behavior.
