Stereologic estimation of nuclear volume in glottic squamous-cell carcinoma

Area of Science:

• Oncology
• Pathology
• Stereology

Background:

• Glottic carcinoma is a significant cause of cancer mortality.
• Accurate prognostic markers are crucial for effective treatment planning.

Purpose of the Study:

• To evaluate the prognostic value of mean nuclear volume (nuclear (V) over bar v) in glottic carcinomas.
• To determine if nuclear (V) over bar v can serve as an independent prognostic marker.

Main Methods:

• A stereologic model, the point sample intercept technique, was used to estimate nuclear (V) over bar v.
• Analysis was performed on 106 formalin-fixed, H&E-stained glottic carcinoma sections.
• Univariate and multivariate analyses were conducted to assess prognostic significance.

Main Results:

• The overall average nuclear (V) over bar v was 782 μm³.
• Patients with glottic carcinoma who died had a significantly higher nuclear (V) over bar v (917 μm³) compared to survivors (713 μm³).
• A cut-off level of 900 μm³ effectively separated favorable and poor prognostic cases (p=0.0004).
• Multivariate analysis identified N-stage and nuclear (V) over bar v as independent prognostic factors for survival.

Conclusions:

• Mean nuclear volume (nuclear (V) over bar v) is a strong independent prognostic marker in glottic carcinomas.
• Increased nuclear (V) over bar v is associated with a poorer prognosis.
• Nuclear (V) over bar v can aid in risk stratification and treatment decisions for glottic cancer patients.
