Clinicopathological and Ultrasonographic Characteristics of Breast Cancer in Young Women

Abstract

Purpose:

The early detection of breast cancer in women under the age of 40 has posed significant challenges. This can be attributed in part to the limited research conducted on the breast cancer in this age group, particularly with regards to large sample sizes. We aimed to address this gap by analyzing and comparing the ultrasound imaging and pathological characteristics of breast cancer in women aged under 40 and those aged 40 and above.

Methods:

A retrospective assessment was conducted to examine the ultrasound imaging and clinicopathologic characteristics of 555 women with surgically confirmed breast cancers. The patient cohort consisted of 160 individuals below the age of 40 and 395 individuals aged 40 years and above.

Results:

Our study identified the breast cancer in patients under 40 years was more likely to show regular shape (p = 0.043) compared with tumors in patients who were 40 years and over. Furthermore, in young female patients (<40 years), irregular shape was correlated with the HER2-enriched type (p = 0.02), circumscribed margin (p = 0.001), and a lack of calcifications (p = 0.02) were associated with the triple-negative type. In another group (≥40 years), only a lack of calcifications (p = 0.003) were associated with the triple-negative type.

Conclusion:

Breast cancer in women under the age of 40 exhibits distinct ultrasonographic characteristics patterns that vary across different immunophenotypes, which may provide certain predictive information for physicians.
