Feasibility study comparing synthesized mammography with digital breast tomosynthesis and digital mammography for simulated first round screening in a single BreastScreen NSW centre.

Introduction: While digital breast tomosynthesis (DBT) has proven to enhance cancer detection and reduce recall rates (RR), its integration into BreastScreen Australia for screening has been limited, in part due to perceived cost implications. This study aims to assess the cost effectiveness of digital mammography (DM) compared with synthesized mammography and DBT (SM + DBT) in a first round screening context for short-term outcomes.

Methods: Clients recalled for nonspecific density (NSD) as a single lesion by both readers at the Northern Sydney Central Coast BreastScreen service in 2019 were included.

Radio-isotope occult lesion localization (ROLL) techniques to identify the clipped node for targeted axillary dissection (TAD) in breast cancer.

Background: Breast cancer patients having neoadjuvant systemic therapy (NAST) who have a positive (clipped) lymph node (CN) at presentation must have that CN removed to assess pathologic response at later surgery. Multiple techniques for localizing the CN have been described. We describe a novel ROLL-based approach.

Impact of selective use of breast MRI on surgical decision-making in women with newly diagnosed operable breast cancer.

Background: This study evaluated the impact of breast MRI on surgical planning in selected cases of breast malignancy (invasive cancer or DCIS). MRI was used when there was ambiguity on clinical and/or conventional imaging assessment.

Methods: Consecutive women with breast malignancy undergoing breast MRI were included.

The influence of knowledge of mammography findings on the accuracy of breast ultrasound in symptomatic women.

Breast ultrasound is generally interpreted with knowledge of the mammographic examination. This study examined the influence of knowledge of mammography findings on the accuracy of ultrasound in women with breast symptoms. Subjects were sampled from all women 25-55 years of age consecutively attending a breast clinic.

The influence of clinical information on the accuracy of diagnostic mammography.

Objective: This study examined the influence of knowledge of clinical information on the accuracy of mammography in women referred for investigation of breast symptoms.

Methods: Subjects were sampled from all women consecutively attending a symptomatic breast clinic and aged 25-55 years. This included all 240 women shown to have breast cancer and 240 age-matched women shown not to have cancer.

Sydney Breast Imaging Accuracy Study: Comparative sensitivity and specificity of mammography and sonography in young women with symptoms.

Objective: We examined the age-specific sensitivity and specificity of mammography and sonography in symptomatic women to determine the age below which sonography may be the more accurate imaging test, which may guide the choice of initial breast imaging examination based on the woman's age.

Materials And Methods: Four hundred eighty subjects were sampled from all women consecutively attending a symptomatic breast clinic between 1994 and 1996 and ranging in age from 25 to 55 years. We included all 240 women shown to have breast cancer (thus avoiding selection bias) and 240 age-matched women shown not to have cancer.
