e11604 Background: Several authors reported sentinel lymph node biopsy after neoadjuvant chemotherapy. Nevertheless, the ideal time of sentinel lymph node biopsy is still a matter of debate. Methods: We evaluated the feasibility and the accuracy of sentinel lymph node biopsy before neoadjuvant chemotherapy using a combined procedure (blue dye and radio-labelled detection) in a homogeneous cohort study with clinically axillary node-negative breast cancer. Study candidates were patients referred to the Institut Paoli-Calmettes Cancer Center (Marseille, France) for the treatment of invasive breast cancer. Patients were included in the study if they had tumor more than 3 cm in diameter without palpable axillary lymph node for which a neoadjuvant chemotherapy was indicated in order to enhance the likelihood of breast conservation. An axillary lymph node dissection was performed after completion of neoadjuvant chemotherapy. Results: From September 2005 to September 2007, thirty-one women with T2 or T3 invasive breast cancer without palpable axillary lymph node underwent sentinel lymph node biopsy before neoadjuvant chemotherapy and an axillary lymph node dissection after neoadjuvant chemotherapy. Among the 20 women who had metastatic sentinel lymph node biopsy (65%), 4 (20%) had additional metastatic node on axillary lymph node dissection. By contrast, all the 11 women who had no metastatic sentinel lymph node biopsy had no involved nodes in the axillary lymph node dissection. The sentinel lymph node biopsy identification rate before neoadjuvant chemotherapy was 100% with any false negative. Conclusions: Sentinel lymph node biopsy before neoadjuvant chemotherapy is a feasible and an accurate diagnostic tool to predict the pre-therapeutic axilla status. These findings suggest that axillary lymph node dissection may be avoided in patients with a negative sentinel lymph node biopsy performed before neoadjuvant chemotherapy.

Abstract Aims NICE guidelines have not defined the timing of Sentinel Lymph Node Biopsy (SLNB) with respect to neoadjuvant chemotherapy (NACT). While there is an ongoing debate, the emerging consensus is in favour of SLNB following NACT in clinically node-negative (cN0) patients which confers the advantage of better prognostic outcomes as a negative SLNB negates further Axillary Lymph Node Dissection (ALND) and prevents patients having further unnecessary surgery. Thus, the aim of the study was to establish whether unnecessary ALND can be safely avoided by performing SLNB after NACT. Method Retrospective case records review of all patients treated with ALND at a single institution was undertaken from January 2018 to December 2019. Results 73 patients had ALND in this time frame. Patients received SLNB before NACT and ALND was performed if they were found node-positive on SLNB. Out of 73 patients, 24 patients had no further nodal disease, 26 had 1-2 macrometastasis and 23 had 3 or more macrometastasis on ALND. 57/73 patients had early breast cancer (T1/T2). 21/57 were cN0 but and 5/21 had NACT following SLNB and ALND after NACT. Of the 5 patients, 2 (40%) had no nodal disease on ALND. Conclusion 40% patients could have avoided ALND if SLNB was done after NACT. Also, 68% (50/73) patients who had ALND only had <2 lymph node macrometastasis. This data implies that patients with early breast cancer may be getting subjected to a second operation which not only is unnecessary but also may have debilitating complications.

Node Biopsy

Sentinel lymph node biopsy (SLNB) is routinely performed as an axillary staging procedure for breast cancer. Although the reported false-negative rate approaches 10 per cent, this does not always lead to axillary recurrence. We previously reported an axillary recurrence rate of 1 per cent at a median follow-up of 2 years. Our objective is to determine the rate of axillary recurrence with longer follow-up. A retrospective review of patients with invasive breast cancer and a negative SLNB treated between 2001 and 2005 was performed. Cases where neoadjuvant therapy was used or where isolated tumor cells (ITCs) were found were included, whereas those with fewer than 18 months of follow-up were excluded. One (0.7%) out of 139 patients had an axillary recurrence after a median follow-up of 52 months. No patient who underwent neoadjuvant chemotherapy or with ITCs had axillary recurrence. Twelve (8.6%) patients have died, with death attributed to breast cancer in three. Our study demonstrates that axillary recurrence after SLNB remains a rare event after a median follow-up of 52 months, despite including potentially higher risk scenarios such as where neoadjuvant chemotherapy is used and ITCs are found. Therefore, axillary lymph node dissection can safely be avoided in patients where SLNB is negative.
