Brief Summary:

To compare accuracy of ultrasound guided fine needle aspiration (FNA) to core needle biopsy (CNB) of ultrasound detected abnormal axillary lymph nodes in patients with newly diagnosed invasive breast cancer or suspected invasive breast cancer.

Hypothesis: FNA and CNB have equivalent diagnostic accuracies

In order to prove our hypothesis, we will perform FNA and CNB on the same lymph node in each consented patient. The two samples will be evaluated separately by different pathologists blinded to the material in the other sample.

The results of the biopsies will be compared to the gold standard (lymph node excision).

Arm Intervention/treatment
Abnormal lymph nodes
There is only one arm to this study and includes all eligible and consented patients with abnormal axillary lymph node on ultrasound.
Procedure: FNA and Core biopsy
Both procedures will be performed on the same lymph node




Primary Outcome Measures :
  1. Accuracy of FNA and CNB [ Time Frame: 2 years ]
    Accuracy will be determined by comparing the results of the FNA and CNB performed on the same lymph node to the gold standard using a paired test of equivalence. The gold standard is the final pathologic diagnosis of excised lymph node containing biopsy marker (either sentinel lymph node biopsy or axillary dissection). Surgical excision of pre-operatively sampled lymph node marks the end of study participation for each patient.


Secondary Outcome Measures :
  1. Pain associated with FNA and CNB [ Time Frame: 2 years ]
    Pain associated with each biopsy method will be assessed with a visual analog scale (0- 10) after a baseline pain measurement. The results will be compared to baseline pain level and analyzed using a paired t test.
