Hypothesis
To compare radiographic measurement and pathological measurement of renal tumours to see if there was a significant difference between the two.
Conclusion
CT measurement of renal tumour size correlates well with the actual size of the tumour, but can overestimate size in some patients, affecting treatment decisions.
Supporting Evidence
- CT tended to overestimate the size of tumours in 41 patients.
- CT underestimated the size in 45 patients.
- In 5% of patients, the pathological size was ≤ 40 mm despite CT indicating size > 40 mm.
Takeaway
Doctors use CT scans to measure kidney tumours, but sometimes the scans say the tumours are bigger than they really are, which can change how they treat patients.
Methodology
Retrospective analysis of CT measurements compared to pathological measurements in patients who underwent surgery.
Potential Biases
Potential bias from using different radiographic imaging equipment and varying reporting techniques.
Limitations
Results are subject to observational variability and discrepancies due to lack of standardization in measurement techniques.
Participant Demographics
Mean age 64 years, 76 males and 30 females.
