Hypothesis
Can low- and high-proliferative soft tissue sarcomas be differentiated using conventional imaging and radiomics features on MRI?
Conclusion
Several imaging features can help distinguish between low- and high-proliferative soft tissue sarcomas.
Supporting Evidence
- Metastases were more prevalent in high-proliferative soft tissue sarcomas.
- Time till metastasis negatively correlated with the Ki-67 proliferation index.
- Several radiomics features representing intratumoral heterogeneity differed significantly between both groups.
Takeaway
Doctors can tell if a soft tissue tumor is growing fast or slow by looking at special pictures from an MRI.
Methodology
This retrospective study analyzed MRI features of soft tissue sarcomas categorized by their Ki-67 proliferation index.
Potential Biases
Potential bias due to the retrospective nature and the reliance on available imaging data.
Limitations
The study is retrospective and conducted at a single center, which may limit the generalizability of the findings.
Participant Demographics
The study included 118 patients, with a similar distribution of males and females across low- and high-proliferative groups.
