Abstract Purpose In the ACOSOG Z0011 trial, completing axillary lymph node dissection (cALND) did not benefit patients with T1–T2 cN0 early breast cancer and 1–2 positive sentinel lymph nodes (SLN) undergoing breast-conserving surgery (BCT). This paper reports cALND rates in the clinical routine for patients who had higher (T3–T4) tumor stages and/or underwent mastectomy but otherwise met the ACOSOG Z0011 eligibility criteria. Aim of this study is to determine cALND time trends and non-sentinel axillary metastases (NSAM) rates to estimate occult axillary tumor burden. Methods Data were included from patients treated in 179 German breast cancer centers between 2008 and 2015. Time-trend rates were analyzed for cALND of patients with T3–T4 tumors separated for BCT and mastectomy and regarding presence of axillary macrometastases or micrometastases. Results Data were available for 188,909 patients, of whom 19,009 were identified with 1–2 positive SLN. Those 19,009 patients were separated into 4 cohorts: (1) Patients with T1–T2 tumors receiving BCT (ACOSOG Z0011 eligible; n = 13,741), (2) T1–T2 with mastectomy (n = 4093), (3) T3–T4 with BCT (n = 269), (4) T3–T4 with mastectomy (n = 906). Among patients with T3–T4 tumors, cALND rates declined from 2008 to 2015: from 88.2 to 62.6% for patients receiving mastectomy and from 96.6 to 58.1% in patients receiving BCT. Overall rates for any NSAM after cALND for cohorts 1–4 were 33.4%, 42.3%, 46.9%, 58.8%, respectively. Conclusions The cALND rates have decreased substantially in routine care in patients with ‘extended’ ACOSOG Z0011 eligibility criteria. Axillary tumor burden is higher in these patients than in the ACOSOG Z0011 trial.

1103 Background: The American College of Surgeons Oncology Group (ACOSOG) Z0011 trial demonstrated that, for patients with clinical T1-T2, N0 breast cancer and one or two positive sentinel lymph nodes undergoing breast conserving therapy, there was no difference in local-regional recurrence (LRR), disease-free survival or overall survival (OS) between patients who underwent sentinel lymph node dissection (SLND) alone or completion axillary lymph node dissection (ALND). However, there were a limited number of invasive lobular carcinoma (ILC) participants (7%) in the study. In addition, it is known that ILC has a different pattern of metastases, frequently presenting as small foci requiring immunohistochemistry for detection. Together, these considerations raise concern regarding the applicability of the ACOSOG Z0011 data to patients with ILC. Methods: Patients with ILC who met the ACOSOG Z0011 eligibility criteria were identified from the Surveillance, Epidemiology, and End Results database (1998-2009). Patients were evaluated based on the extent of axillary surgery: SLND alone or ALND. Clinicaloutcomes of the two groups were compared. Results: At a median follow-up of 71 months, there were no LRRs in the SLND arm, and only 4 (0.45%) in the ALND arm. There were no differences in OS or disease-specific survival between the two groups. Conclusions: Omission of completion ALND is appropriate in patients with ILC who fulfill the ACOSOG Z0011 eligibility criteria.

62 Background: A relatively newer algorithm for surgical management of axilla, where axillary node dissection (ALND) is avoided in cN0 EBC patients with 1 to 2 metastatic sentinel nodes (SLN) is now widely practiced in North America. ASCO & NCCN guidelines, and St Gallen consensus statement too have endorsed this strategy. This algorithm, based on the ACOSOG-Z0011 trial results has evoked quite a debate in India too. Concerns relating the quality of Z0011 data and its wide applicability persist. On the other hand, avoidance of ALND and its morbidity seems attractive to the oncologists and patients. In a single institution validation SLN Biopsy (SLNB) data-set, we evaluated the applicability of the “Z0011 strategy” to know its impact on an Indian patient cohort. Methods: In a prospective data-set of 120 cN0 EBC patients (mean age 51.1 years, T1 = 14, T2 = 106, mean tumor size 3.8 cm, 51.7% ER/PR+) who underwent validation SLNB (ALND irrespective of SLNB histology), such patients who fulfilled the selection criteria of ACOSOG-Z0011, i.e. those who underwent BCS and tangential field whole breast irradiation, and 1-2 metastatic SLNs were identified. Results: 66 (55%) of the 120 patients underwent BCS and tangential field whole breast irradiation. Of the 25 out of 66 patients with metastatic SLNs, 5 patients had 3 or more metastatic SLNs, and 2 had extra-nodal spread, thus not fitting the Z0011 criteria. Thus only 18 patients (15% of entire study cohort, and 27.3% of those undergoing BCS) with 1 to 2 metastatic SLNs were eligible for avoidance of ALND based Z0011 criteria. Of these 18 eligible patients, 7 (38.9%) had non-sentinel metastatic nodes. These 7, and the 3 with false negative SLNs could be seen as being left with undertreated axillae. Conclusions: In Indian context, where the majority of patients have large tumors and many opt for mastectomy, avoidance of ALND in presence of metastatic SLNs can be offered to a small proportion of patients. In a single institution validation SLNB data-set, only 15% patients qualified for avoidance of ALND using the Z0011 trial criteria. Besides, avoidance of ALND would have left 8.3% patients potentially undertreated in the axilla.
