    Summary
    This summary is machine-generated.

    Nipple preservation during mastectomy is safe for select breast cancer patients. This approach, for peripheral tumors, showed no increase in local recurrence and improved cosmetic outcomes.

    Area of Science:

    • Surgical Oncology
    • Breast Cancer Research
    • Pathology

    Background:

    • Microscopic involvement of the nipple-areola complex (NAC) in operable breast cancer occurs in a subset of patients.
    • Tumor location and axillary lymph node status are critical factors influencing NAC involvement.

    Purpose of the Study:

    • To evaluate the incidence of nipple involvement in breast cancer patients.
    • To identify criteria for safe nipple preservation during mastectomy.
    • To assess the impact of nipple preservation on cosmetic outcomes and local recurrence rates.

    Main Methods:

    • Retrospective analysis of 100 operable breast cancer patients to determine nipple involvement.
    • Prospective evaluation of 60 patients undergoing mastectomy with nipple preservation based on defined criteria.

  • Fisher's exact test and chi-squared test for statistical analysis.
  • Frozen section analysis of the sub-nipple area.

    • Main Results:

    • Nipple involvement was observed in 16% of cases, exclusively in those with centrally located tumors.
    • Peripheral tumors located >2 cm from the areolar margin did not show nipple involvement (P < 10^-6).
    • Nipple involvement was significantly associated with ≥4 positive axillary nodes (P < 0.01).
    • Nipple preservation criteria were met by 20/60 prospective patients.
    • Improved cosmetic results (35%) and facilitated skin closure (20%) were noted with nipple preservation.
    • No significant increase in local recurrences was observed after a mean follow-up of 50.4 months.

    Conclusions:

    • Nipple preservation during mastectomy is feasible for small peripheral breast tumors when clinically normal and confirmed free of invasion via frozen section.
    • This technique can enhance cosmetic outcomes in breast reconstruction.
    • Nipple preservation does not compromise local recurrence control in carefully selected patients.
