Invasive ductal carcinoma of the breast in a 14-year-old girl

Paediatric and Adolescent Breast Cancer: A Narrative Review

Breast cancer is the most prevalent form of cancer worldwide. Every year, it affects a significant number of women in the UK and is considered one of the leading causes of cancer-related deaths globally. While breast cancer is primarily linked to adult women, its occurrence in children and adolescents is exceedingly rare. This study conducted a narrative review spanning from 1999 to 2023, examining 32 case reports to investigate the characteristics of breast cancer in the paediatric age group. These reports focused on patients under 18 years old who were diagnosed with primary glandular breast cancer, excluding cases originating from other tissues like angiosarcoma, leukaemia, and metastatic cancer. The data analysis encompassed various parameters, including gender, age, histology, receptor status, lymph node involvement, treatment methods, and genetic characteristics. From the published case reports, it was concluded that the most common type of breast cancer affecting children and adolescents is secretory breast carcinoma and predominantly occurs in females. It is typically hormone receptors negative, and the preferred treatment approach involves mastectomy as breast conservation surgery to preserve the developing breast tissue is a real challenge due to limited breast tissue volume in this age group.

Comparison of the Radiologic and Clinical Findings of Adolescents With Breast Complaints

INTRODUCTION

The American College of Radiology's Breast Imaging Reporting and Data System (BI-RADS) was developed to guide imaging-based surgical treatment in patients with breast cancer. Studies confirming the BI-RADS did not include adolescents. To evaluate the validity of this classification system in adolescents, we aim to investigate the relationship between the BI-RADS and pathology findings in adolescents.

METHODS

The medical data of 67 female adolescent patients, aged 12 to 18, referred to our clinic for breast-related complaints between 2013 and 2016 were reviewed retrospectively for demographic data and the results of radiologic and surgical pathologies.

RESULTS

The main underlying reasons for the visit at the clinic were fullness, tenderness, pain, and palpable masses. Of the 67 patients, 46 were enrolled in the study. After breast ultrasonography, patients whose complaints had diminished were subtracted from the follow-up. The mean age of the patients was 16 years (12 to 18 y). The mean mass diameter size was 3.69 cm (0.9 to 15 cm), and the mean clinical follow-up was 65.3 days (11 to 1095 d). All the patients who were surgically intervened had benign pathology. Of the 21 surgically intervened patients with BI-RADS levels of ≥3, most had fibroadenomas.

CONCLUSIONS

The BI-RADS classification-based treatment algorithm may not be valid in adolescents. In the present study, all patients with lesions with BI-RADS ≥3 levels had revealed benign pathologies. The BI-RADS classification may show an increased risk. However, to determine the need for a biopsy in adolescents, there is a need for larger-scale pediatric and adolescent studies using the BI-RADS classification.
