    Elevated serum copper levels indicate gynecologic tumors in women. This biomarker shows high sensitivity for detecting malignancy, especially in advanced stages, aiding in cancer screening.

    Area of Science:

    • Gynecologic Oncology
    • Biochemistry
    • Cancer Biomarkers

    Background:

    • Gynecologic tumors present a significant health challenge.
    • Early detection of gynecologic malignancies is crucial for improved patient outcomes.
    • Biochemical markers are being investigated to enhance cancer screening protocols.

    Purpose of the Study:

    • To evaluate serum copper levels as a potential biomarker for gynecologic tumors.
    • To assess the correlation between serum copper levels and tumor stage.
    • To determine the sensitivity of serum copper levels in detecting malignancy.

    Main Methods:

    • Serum copper levels were measured preoperatively in 179 patients with gynecologic tumors (malignant, benign, ovarian metastases).
    • Patients were categorized by tumor type and stage.

  • Statistical analysis was performed to compare copper levels between groups and with controls.

    • Main Results:

    • Serum copper levels were significantly elevated in patients with malignant and benign gynecologic tumors compared to controls (p < 0.01).
    • A strong correlation was observed between serum copper levels and cancer stage (r = 0.70–0.79), except in ovarian carcinoma where levels were high even in early stages.
    • Serum copper levels > 150 µg/dL demonstrated 87%–100% sensitivity for detecting malignancy in late stages.

    Conclusions:

    • Serum copper levels are significantly elevated in patients with gynecologic tumors.
    • Serum copper may serve as a sensitive biomarker for gynecologic malignancy detection.
    • Incorporating serum copper level testing could improve the sensitivity of existing cancer screening methods.
