Does Shamblin’s classification predict postoperative morbidity in carotid body tumors? A proposal to modify Shamblin’s classification

Abstract: The objective of this study was to analyze the possible correlation between Shamblin's classification and post-surgical morbidity in the treatment of carotid body tumors (CBTs). Seventy-two patients with carotid body tumors were seen over a 22-year period. Twenty-three patients were excluded as they did not comply with the criteria of the objectives. All patients were grouped according to Shamblin's classification. We propose a modification to this classification and make a comparison by analyzing the surgical… Show more

“…Advances in imaging have led to attempts to assign this classification preoperatively; however, some authors have stated that CBTs can only be given a Shamblin classification at or after surgery. 20 A recent small study of nine CBTs suggested that MRI can accurately predict Shamblin group preoperatively, and the maximum degree of circumferential contact of the CBT with the ICA on axial images is the criterion to predict the Shamblin group. In that study, tumor size and Shamblin group did not have a uniformly predictable relationship.…”

“…12 This Shamblin class tumors that infiltrate the vessel walls at any site, regardless of size or need for reconstruction, with subsequent confirmation of infiltration clinically or histologically. 12 Postoperative complications are numerous and include transient ischemic events and stroke, cranial nerve dysfunction, hematoma causing respiratory obstruction necessitating surgical airway and death. 13 Of particular note is that of cranial nerve dysfunction, affecting approximately 30e40% of patients with Shamblin type 3 tumors.…”

“…14 In addition, early surgical resection avoids the increase in risk of postoperative neurological and vascular complications associated with increased tumor size. 12,18 Ongoing surveillance is required for patients with a familial disposition, bilateral tumors, or incomplete resections 19 because of the higher risk of malignancy or recurrence. …”
