    Summary
    This summary is machine-generated.

    Sclerosis promotes cancer development in both peripheral lung carcinoma (PLC) and renal-cell carcinoma (RCC). Scarring and tissue damage create a precancerous environment, leading to abnormal cell growth and ultimately carcinoma.

    Area of Science:

    • Oncology
    • Pathology
    • Morphological analysis

    Context:

    • Sclerotic changes in peripheral lung carcinoma (PLC) and renal-cell carcinoma (RCC) were investigated.
    • The role of fibrosis and scarring in cancer development was examined.

    Purpose:

    • To establish the promoting role of sclerosis in carcinoma development.
    • To elucidate the mechanisms of carcinoma morphogenesis against a sclerotic background.

    Summary:

    • Morphological analysis revealed a high incidence of PLC within scars (83%) and metapneumonic pneumosclerosis foci.
    • Metadiagnostic foci were detected in 75% of PLC cases, with precancerous epithelial changes including DNA and oncogene expression alterations.
    • Renal-cell carcinoma (RCC) showed an 82.7% association with nephrosclerosis, with epithelial proliferation and altered DNA content in sclerotic foci.

    Impact:

    • Demonstrates sclerosis as a significant background factor in PLC and RCC development.
    • Highlights the potential for precancerous changes in epithelial cells within sclerotic tissue.
    • Provides a framework for understanding carcinoma morphogenesis in the context of sclerosis.
