Summary
Hardness of carotid body tumors (CBTs) impacts surgery. Imaging biomarkers like CBT/SCM ratio on T2WI and perivascular fat space erosion can predict CBT hardness, aiding preoperative risk assessment.
Area of Science:
- Neuroendocrine Neoplasms
- Surgical Oncology
- Radiology
Background:
- Carotid body tumors (CBTs) are rare neuroendocrine neoplasms.
- Tumor hardness correlates with surgical complexity and perioperative complications.
- Predictive imaging biomarkers for CBT hardness are needed.
Purpose of the Study:
- To identify predictive multimodal imaging biomarkers of carotid body tumor hardness.
- To correlate imaging findings with surgical outcomes and complications.
Main Methods:
- Retrospective cohort study of 82 patients with surgically resected CBTs.
- Analysis of preoperative multimodal imaging and clinical data.
- Tumor hardness assessed by Masson-stained fibrous proportion; multivariate logistic regression used.
Main Results:
- Hard CBTs associated with longer operative times and increased perioperative complications.
- Differences in MRI signal homogeneity (T1WI, T1WI-CE) observed between soft and hard CBTs.
- CBT-to-sternocleidomastoid muscle (SCM) ratio on T2WI and perivascular fat space (PFS) erosion are significant predictors of hardness (p < 0.001).
Conclusions:
- CBT/SCM ratio on T2WI and PFS erosion show promise as imaging biomarkers for CBT hardness.
- These biomarkers may aid in preoperative risk stratification for carotid body tumors.
- Further prospective validation is required to confirm these findings.
