[Cytologic grade, a prognostic factor in breast cancer]

Area of Science:

• Oncology
• Cytopathology

Context:

• Fine needle aspiration (FNA) is a common diagnostic technique for breast lesions.
• Papanicolaou staining is a standard cytological staining method.

Purpose:

• To evaluate the prognostic value of cytological grading from FNA of breast carcinomas.
• To correlate cytological findings with clinical outcomes and staging.

Summary:

• A hypochromic Papanicolaou staining procedure for breast carcinoma FNA yielded prognostic data.
• Three grades of increasing severity were established.
• Analysis of 189 patients showed significantly higher rates of adverse outcomes in Grade III compared to Grades I and II within 1-5 years.
• Cytoprognostic classification strongly correlated with TNM staging and lymph node involvement.
• Grade III identified patients with high metastatic potential, with increased recurrence rates even in early stages or without lymph node involvement.
• Absence of steroid receptors further confirmed the poor prognosis associated with Grade III.

Impact:

• This cytoprognostic classification can improve patient risk stratification.
• It aids in identifying patients who may benefit from more aggressive therapeutic management.
• Findings support the integration of cytological grading into routine breast cancer prognostication.
