Brief summary

The purpose of this study is to determine if a 3-dimensional mammogram (DBT) may provide additional information to evaluate the extent of disease and additional findings that would aid in staging a new breast cancer patient. This would impact surgical planning and improve patient outcomes.

Detailed description

Primary Objective: The primary objective of the study is to measure the frequency with which DBT alters the surgical plan to mastectomy versus lumpectomy. Only positive findings, like an additional site of cancer or DCIS, will be taken into account when estimating the frequency of changes to surgical management. Secondary objectives: 1. To measure the frequency and nature of additional findings like atypical pathology (Atypical ductal/ lobular hyperplasia, papilloma, Lobular carcinoma in situ (LCIS) , requiring surgical intervention). 2. To identify variables on 2D (e.g. dense breasts, architectural distortions, non calcified masses) that might predict which patients would benefit from DBT. 3. To measure the proportion of patients undergoing additional work-up following the DBT, and the subset of these patients with benign findings (i.e. False Positives).

Interventions

DEVICE2-dimensional mammogram

This is standard of care for breast cancer diagnosis. The new breast cancer patients will be scheduled for the mammogram after diagnosis at the time of surgical appointment. The radiologist reviewing the tomosynthesis images will be separate and blinded from the radiologist who reviewed the initial 2-D mammogram.

The radiation dose from this/these procedure(s) will be no more than 0.4mSv for a bi-lateral breast tomosynthesis. The new breast cancer patients will be scheduled for the mammogram after diagnosis at the time of surgical appointment. The radiologist reviewing the tomosynthesis images will be separate and blinded from the radiologist who reviewed the initial 2-D mammogram.
