Background: The sentinel lymph node biopsy (SLNB) is the standard procedure to assess the lymph node status in women with early stage breast cancer. It is uncertain whether SLNB is useful after neo-adjuvant chemotherapy (NACT) given to women with locally advanced breast cancer. Materials and Methods: A literature search was conducted over a timeframe of 22 years (1994-2016). Forty-three studies evaluating the feasibility and accuracy of SLNB after NACT were identified. Results: The pooled identification rate was 88% and the pooled false negative ratio was 12%. Conclusion: SLNB could be considered as a standard procedure after NACT.
