ABSTRACT
OBJECTIVES:
The results of the ACOSOG Z0011 questioned the usefulness of axillary lymph node dissection (ALND) in case of metastatic sentinel lymph node (SLN). The aim of our study was to assess the impact of the omission of ALND according to the inclusion criteria of the ACOSOG Z0011 study if SLN are metastatic but also the consequences on prescription of the application of a new standard of care for adjuvant treatment. PATIENTS ANDMETHODS:
This retrospective study included, between November 2007 and January 2012, patients with T1-T2N0 breast cancer and metastatic SLN meeting the criteria for omission of completion ALND according to the study of the ACOSOG Z0011. Patients were submitted anonymously and randomly in multidisciplinary meeting (MM) 3 times with complete information including ALND (MM1), with information from SLN alone (MM2) and with complete information of ALND according to the current protocols in 2013 (MM3). During each presentation, we collected the decision of the different adjuvant treatments proposed chemotherapy, hormonal therapy, radiotherapy (with radiation fields). Then, we compared therapeutic proposals of the 3 presentations.RESULTS:
Fifty-eight patients were eligible for inclusion criteria of the ACOSOG Z0011. Treatments actually proposed during MM1 consisted of 94.8 % of chemotherapy, 77.6 % of breast and lymph nodes radiotherapy and 91.4 % of hormone therapy. During the MM2, there was no significant difference compared to the decision taken during MM1. In fact, during MM2, we decided chemotherapy, radiotherapy and hormonotherapy respectively in 89.7, 79.3 and 91.4 % of the cases. During the MM3, it was shown a significant decrease in the indications of chemotherapy (82.8 %, P=0.03) and lymph nodes irradiation (56.9 %, P=0.02) compared to the therapeutic proposals of the MM1. DISCUSSION ANDCONCLUSION:
The lack of information of ALND does not seem to significantly alter indications for adjuvant treatment. Otherwise, the evolution of our references causes a decrease in adjuvant therapy.Palavras-chave
