    This study proposes a diagnostic sector mastectomy for obscure primary breast cancer with axillary metastases. This approach offers a better prognosis than aggressive treatments, guiding subsequent therapy effectively.

    Area of Science:

    • Oncology
    • Surgical Oncology
    • Diagnostic Procedures

    Background:

    • Axillary lymph node metastases without a clear primary tumor present a diagnostic challenge.
    • Optimal therapeutic strategies for such cases remain debated, impacting patient prognosis.

    Purpose of the Study:

    • To evaluate a diagnostic and therapeutic approach for patients with axillary lymph node metastases of unknown primary origin.
    • To compare the proposed method with existing conservative and aggressive treatment strategies.

    Main Methods:

    • Retrospective analysis of eight patients with axillary lymph node metastases and obscure primary tumors.
    • Proposed diagnostic sector mastectomy of the upper outer quadrant of the ipsilateral breast.
    • Subsequent treatment based on diagnostic findings: modified radical mastectomy or axillary block dissection with radiotherapy.

    Main Results:

    • Five out of eight patients had an obscure primary tumor location initially.
    • Three patients were found to have primary breast tumors in the adjacent breast.
    • Seven patients demonstrated a relatively good prognosis compared to literature benchmarks.

    Conclusions:

    • Blind radical mastectomy and radiotherapy alone are deemed inappropriate for this condition.
    • Sector mastectomy serves as a valuable diagnostic tool for obscure primary breast cancer.
    • A tailored therapeutic strategy based on diagnostic findings improves patient outcomes.
