Improving Reporting of Tumor Size in Synoptic Reports

Area of Science:

• Pathology
• Oncology
• Medical Reporting

Background:

• Tumor size is a critical prognostic factor in cancer diagnosis.
• Standardized reporting formats for tumor size in synoptic reports are lacking.

Purpose of the Study:

• To identify formatting characteristics of tumor size reporting that influence its prognostic significance.
• To improve the accuracy and utility of tumor size data in pathology reports.

Main Methods:

• Review of various formatting features for tumor size in synoptic reports.
• Correlation analysis of formatting features with tumor size distribution, reproducibility, and other pathological indicators.

Main Results:

• Reporting tumor size in millimeters, as opposed to centimeters, significantly improved reproducibility (P = .01) due to reduced rounding errors.
• Tumors noted as potentially underestimated in size, or reported as multifocal, showed significantly higher N stage compared to unifocal tumors of similar reported size.

Conclusions:

• Tumor size should be reported in millimeters for enhanced precision.
• Special attention should be given to "at least" size and "multifocal" tumor designations, as these may underestimate tumor burden and biologic potential, correlating with higher N stage.
