    Summary
    This summary is machine-generated.

    Autopsy of 26 Ewing sarcoma patients revealed metastases in 23 cases, primarily in lungs and bones. Three deaths resulted from treatment complications, not residual tumor, highlighting treatment risks in Ewing sarcoma care.

    Area of Science:

    • Oncology
    • Pathology
    • Radiotherapy

    Background:

    • Ewing sarcoma is a rare bone and soft tissue cancer.
    • Treatment often involves radiation and chemotherapy.
    • Autopsy studies are crucial for understanding treatment outcomes and disease progression.

    Purpose of the Study:

    • To evaluate the efficacy of radiation and chemotherapy in Ewing sarcoma.
    • To determine the patterns of metastasis in treated Ewing sarcoma.
    • To identify prognostic indicators in post-treatment autopsies.

    Main Methods:

    • Retrospective autopsy study of 26 Ewing sarcoma cases.
    • Analysis of tumor presence, location, and histological characteristics.
    • Correlation of autopsy findings with treatment regimens.

    Main Results:

    • Metastatic Ewing sarcoma was found in 23 out of 26 cases.
    • Common sites of metastasis included lungs, pleura, bones, and lymph nodes.
    • Residual tumor in the primary site was observed in 13 of 20 cases; 3 deaths were treatment-related.

    Conclusions:

    • Adjuvant chemotherapy and radiation show limited efficacy in preventing metastasis in Ewing sarcoma.
    • Histological features like pleomorphism and giant cells did not alter glycogen presence, confirming its diagnostic value.
    • Treatment complications represent a significant cause of mortality in Ewing sarcoma patients.
