Similarly, the number of metastatic axillary lymph nodes
in patients who died was statistically significantly higher than in patients who survived.20 Despite the limited number of patients present in our study,findings suggest that axillary lymph node
metastasis and the stage of the disease affect survival significantly.
Axillary lymph nodes
were examined for the total number of lymph nodes removed, number of positive lymph nodes (pN), and lymph node ratio (LNR.) The number of positive lymph nodes on histopathological examination was stratified according to the staging system of the American Joint Committee on Cancer and The Union for International Cancer Control (AJCC/UICC) into pNl (1-3 positive lymph nodes), pN2 (4-9 positive lymph nodes), and pN3 (>10 positive lymph nodes) (14, 15).
The axillary lymph nodes
are divided into three different levels as level I level II and level III pectorals minor muscle in used as a Land mark for this division.
Patients, then, underwent modified radical mastectomy with dissection of axillary lymph nodes
(ALN) and the samples were sent for histopathology.
The international, multi-centre, two-arm, randomised, open-label and phase III study was designed to assess the efficacy and safety of Kadcyla against Herceptin as an adjuvant therapy in people with HER2-positive eBC who have pathological residual disease in the breast or axillary lymph nodes
following neoadjuvant therapy that included Herceptin and taxane-based chemotherapy.
Besides, skip metastases to the axillary lymph nodes
may influence surgical and adjuvant treatment of the patient.
In this report, we argue that the histopathological evaluation of axillary lymph nodes
that are considered radiologically suspicious can prevent possible staging errors, as in our case that was diagnosed with primary breast carcinoma.
However, sentinel lymph node (SLN) analysis is the accepted method for staging axillary lymph nodes
There were palpable left axillary lymph nodes
. The rest of the physical examination was unremarkable.

Clinical evaluation of axillary lymph nodes
compared to surgical and pathologic findings.
The co-primary endpoints of the study were risk difference (RD) and risk ratio (RR) of pathologic complete response in breast tissue and axillary lymph nodes
, and the prespecified equivalence margins were +/-13 percent for RD and 0.759 to 1.318 for RR.
