Background:
Breast cancer is the most common malignancy and remains the first cause of death related to cancer among Vietnamese women, with an incidence of 21,555 cases in 2020. Most breast cancer patients present with invasive disease and relatively large tumor sizes. While oncoplastic surgery (OPS) are commonly applied in Western countries, data on Asian population remains relatively limited.
Objective:
This study aims to assess the outcomes of level-2 oncoplastic techniques in breast-conserving surgeries at the Vietnam National Cancer Hospital.
Methods:
From January 2017 to June 2021, a cohort of 257 breast cancer patients who underwent breast-conserving surgery with OPS techniques were examined. Surgical complications, cosmetic outcome, recurrence and survival rates were assessed.
Results:
The mean age was 47.6±9.4 years, most patients had breast cup sizes B and C. The mean tumor size upon pathological examination was 2.00 ± 0.74 cm. Only 7 cases required reoperation, resulting in a mastectomy rate of 1.17%. The overall complication rate was low at 11.46%, with 9 cases (3.56%) experiencing delayed complications. Cosmetic results were rated as "excellent" in 20.6% and "good" in 60.5%, with a statistically significant difference. The rates of local recurrence, regional recurrence, and distant metastasis at five years were 2.78%, 1.19%, and 2.36%, respectively.
Conclusion:
The level 2 oncoplastic techniques had low complication rates, favorable oncological outcomes, and cosmetically satisfying results.
