Nuclear grading in invasive ductal breast carcinomas

Area of Science:

• Oncology
• Pathology
• Cytopathology

Background:

• Accurate grading of breast cancer is crucial for prognosis and treatment decisions.
• Nuclear grade (NG) is a key prognostic indicator in invasive breast carcinomas.
• Assessing NG from fine-needle aspiration (FNA) biopsies can provide timely information.

Purpose of the Study:

• To evaluate the concordance between nuclear grade determined from fine-needle aspiration (FNA) cytologic material and surgical biopsy specimens.
• To correlate nuclear grade with other prognostic factors in breast carcinomas.
• To validate the use of FNA cytology for nuclear grading of breast ductal carcinomas.

Main Methods:

• Cytologic material from 120 FNA breast lesion biopsies were analyzed.
• Nuclear grade was assessed using Fisher's modification of Black's NG scheme.
• Comparison was made between NG from FNA cytology and corresponding surgical biopsy specimens.

Main Results:

• A high agreement rate of 93.33% was observed between the nuclear grade of FNA cytologic material and surgical biopsies.
• Cytologic assessment of nuclear grade for invasive breast carcinomas demonstrated significant concordance with histological findings.
• The study confirmed the feasibility of using FNA cytology for nuclear grading.

Conclusions:

• Fine-needle aspiration biopsy is a reliable method for determining nuclear grade in invasive breast carcinomas.
• Cytologic nuclear grading shows high concordance with histological grading, supporting its clinical utility.
• Further studies correlating nuclear grade with other prognostic factors are warranted.
