Surgical excision margins: a pathologist's perspective.

Area of Science:

• Oncologic Pathology
• Surgical Oncology
• Head and Neck Cancer Research

Background:

• Histopathologic assessment of surgical margins is a key prognostic factor for malignant neoplasms.
• The predictive accuracy of current margin assessments for recurrence and prognosis remains suboptimal.
• Squamous cell carcinomas of the upper aerodigestive tracts have been extensively studied regarding margin significance.

Purpose of the Study:

• To critique current applications and clinical implications of surgical margins in upper aerodigestive tract squamous cell carcinomas.
• To evaluate the impact of margin status on recurrence and patient outcomes.
• To explore novel approaches, including molecular markers, for margin assessment.

Main Methods:

• Review of existing literature on surgical margin assessment in head and neck squamous cell carcinomas.
• Analysis of factors influencing margin measurements, including postremoval artifacts.
• Discussion of specific clinical scenarios: conservation surgery, bone invasion, and molecular markers.

Main Results:

• Current margin assessment methods have limitations in predicting recurrence and prognosis.
• Postremoval artifacts can affect margin measurements.
• Molecular markers like p53 and eIF4E show potential for enhanced margin evaluation.

Conclusions:

• Rethinking current surgical margin assessment strategies is necessary for improved patient care in upper aerodigestive tract cancers.
• Further research into molecular markers and standardized measurement techniques is warranted.
• Optimized margin analysis can lead to better prediction of recurrence and patient outcomes.
