Whole-breast US imaging: four-year follow-up

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• Early detection of breast cancer is crucial for effective treatment.
• Diagnostic accuracy of various breast imaging modalities is an ongoing area of research.

Purpose of the Study:

• To compare the efficacy of physical examination, xeromammography, and whole-breast ultrasound (US) in detecting breast cancer.
• To determine if whole-breast US is a suitable tool for routine breast cancer screening.

Main Methods:

• A prospective study involving 1,140 women between March 1980 and April 1981.
• Independent, blinded interpretation of physical examination, mammography, and whole-breast US results.
• Biopsy-confirmed diagnosis for 125 breast cancers.

Main Results:

• Mammography detected 94% of cancers, while physical examination detected 91%.
• Whole-breast ultrasound (US) detected only 64% of cancers, missing palpable lesions.
• No cancers appeared in the US-suspicious group during a 4-year follow-up, suggesting a high false-positive rate for US.

Conclusions:

• Whole-breast ultrasound (US) is not recommended for routine breast cancer screening.
• Mammography and physical examination demonstrate higher sensitivity for breast cancer detection compared to US.
• Further research may be needed to clarify the role of US in specific clinical scenarios.
