Cytomorphological features, AgNOR counts and c-erb B-2 in carcinoma breast

Area of Science:

• Oncology
• Cytopathology
• Biomarkers

Background:

• Accurate diagnosis and prognostication of carcinoma breast are crucial.
• Cytomorphological features and silver staining nucleolar organiser region (AgNOR) counts are potential diagnostic and prognostic markers.
• Understanding the relationship between these features and patient demographics can improve clinical management.

Purpose of the Study:

• To evaluate cytomorphological features (nuclear grade, smear pattern) and AgNOR counts in carcinoma breast.
• To assess the association between these features, menopausal status, and c-erb B-2 expression.
• To correlate nuclear grade with AgNOR counts for prognostic insights.

Main Methods:

• Analysis of 60 carcinoma breast cases using May Gruenwald Giemsa (MGG) and Papanicolaou stains.
• Assessment of smear patterns (typical, cluster predominant, individual cell type) and nuclear grading (I, II, III).
• Silver staining for AgNOR counts and c-erb B-2 immunostaining performed on all cases.

Main Results:

• A significant association was found between nuclear grade and AgNOR counts (p = 0.03).
• Postmenopausal women exhibited statistically significant higher nuclear grades and less cohesive cell clusters compared to premenopausal women.
• Twenty-three cases (38.3%) were positive for c-erb B-2, with 14 of these being postmenopausal.

Conclusions:

• Cytomorphological features, nuclear grade, and AgNOR counts are valuable in evaluating carcinoma breast.
• Menopausal status influences cytomorphological characteristics and nuclear grade in breast cancer.
• AgNOR counts show a significant correlation with nuclear grade, suggesting prognostic relevance.
