This systematic review and meta-analysis evaluated the diagnostic accuracy of soft tissue cytology using the IAC-IARC-WHO six-tier reporting system. Analyzing 37 studies with 6773 histologically verified cases, the study found a pooled sensitivity of 84.9% and specificity of 96.8%. The risk of malignancy increased significantly across categories, with a post-test probability of malignancy reaching 95%.
Key findings
- Pooled sensitivity of soft tissue cytology was 84.9%.
- Pooled specificity was 96.8%, indicating high diagnostic accuracy.
- Post-test probability of malignancy increased to 95% after a positive result.
- Pooled risk of malignancy was 93.5% for malignant categories.
Why it matters
Understanding the diagnostic accuracy and risk stratification of soft tissue cytology is crucial for clinicians in making informed decisions regarding the management of soft tissue tumors, particularly in preoperative settings.
What to keep in mind
The study's very low certainty of evidence was due to serious concerns regarding risk of bias, indirectness, and inconsistency.
