Pathology Overview - Concepedia

Principles

Definition

Pathology is the scientific study of diseases, investigating their causes, development, and effects on the body. This fundamental medical discipline involves the examination and analysis of tissues, cells, and bodily fluids to provide essential information for diagnosis, management, and research in healthcare.

Key Figures

Cellular-Anatomic Pathology era

Smith Ely Jelliffe [1] was a prominent figure in cellular‑anatomic pathology, with academic associations at Columbia University [3] and Vanderbilt University [4] during the era. One of his key contributions in this era was the comprehensive framing of nervous system diseases in his 1918 volume 'DISEASES OF THE NERVOUS SYSTEM' [7], which linked microscopic pathology to clinical syndromes and helped standardize lesion description. William Osler [2] emerges as a foundational clinician‑pathologist, with affiliations at Johns Hopkins University [5] and the University of Pennsylvania [6] during this period. His The Gulstonian Lectures, on Malignant Endocarditis [8] (1885) exemplified the integration of clinical observation with pathologic anatomy and helped establish organ‑based diagnostic reasoning central to the era.

Molecular Diagnostic Consolidation era

Dennis J. Slamon [1] emerged as a leading figure in molecular pathology during this era, affiliated with the University of California, Los Angeles [3] and the University of Southern California [4]. His landmark paper Human Breast Cancer: Correlation of Relapse and Survival with Amplification of the HER-2/neu Oncogene [7] highlighted HER-2/neu amplification as a prognostic and therapeutic molecular marker, a contribution that anchored the molecular diagnostics emphasis of the era. George C. Ebers [2] stood as a pivotal figure connected with Rockefeller University [5] and Case Western Reserve University [6] in this period. His work New diagnostic criteria for multiple sclerosis: Guidelines for research protocols [8] helped standardize diagnostic criteria and integrate molecular and histologic signals into routine practice, a hallmark of the era.

Immunometabolic Spatial Pathology era

Julie R. Brahmer [1], active in the Immunometabolic Spatial Pathology era, is associated with The University of Texas Southwestern Medical Center [3] and Johns Hopkins University [4]. Her contributions in this era include Safety, Activity, and Immune Correlates of Anti–PD-1 Antibody in Cancer [7] and Nivolumab plus Ipilimumab in Lung Cancer with a High Tumor Mutational Burden [8], which advanced immune checkpoint blockade and combination strategies and enabled biomarker-guided patient selection. Michael B. Atkins [2] has been affiliated with Harvard University [5] and Stanford University [6] in this era. His contributions include Clinical activity and molecular correlates of response to atezolizumab alone or in combination with bevacizumab versus sunitinib in renal cell carcinoma [9], highlighting translational immunotherapy advances and informing precision approaches in immunometabolic contexts.
