    Summary

    Post-operative radiation therapy for early-stage breast cancer achieved excellent local control, especially for Stage I and II disease. Segmental resection followed by irradiation demonstrated superior outcomes compared to tilectomy or biopsy, with good cosmetic results.

    Area of Science:

    • Oncology
    • Radiation Oncology
    • Surgical Oncology

    Context:

    • This study evaluates the efficacy of post-operative radiation therapy in managing primary breast cancers.
    • The research retrospectively analyzes data from 157 patients treated between 1972 and 1979.
    • Patients underwent irradiation following segmental resection, tilectomy, or biopsy for stages I to III breast cancer.

    Purpose:

    • To assess the local control rates and survival outcomes of irradiated breast cancer patients based on surgical approach and disease stage.
    • To determine the impact of different surgical techniques (segmental resection, tilectomy, biopsy) on recurrence rates after irradiation.
    • To evaluate the prognostic significance of tumor size (T-stage) and lymph node status (N-stage) on relapse-free survival.

    Summary:

    • Complete local control was achieved in all Stage I, 97% of Stage II, and 68% of Stage III breast cancers.
    • Segmental resection followed by irradiation showed no recurrence, while tilectomy and biopsy had higher local failure rates.
    • Five-year relapse-free survival rates were 76% for T1, 62% for T2, and 25% for T3/T4 lesions, with N+ status being a negative prognostic factor.

    Impact:

    • The findings highlight the effectiveness of post-operative irradiation in achieving local control for early-stage breast cancer.
    • Segmental resection combined with irradiation appears to be a superior surgical approach for minimizing local recurrence.
    • The study underscores the importance of T-stage and N-stage in predicting outcomes and informs treatment strategies for breast cancer patients.
