Local extension staging of sinonasal tumours: retrospective comparison between CT/MRI assessment and pathological findings

Abstract

Systematic pathologic analysis of the anatomical areas around the sinonasal cancer has to be applied in further studies to improve our therapeutic management. CT/MRI mapping cannot replace accurate assessment of tumour extension during surgery.

Multicenter assessment of exclusive endoscopic endonasal approach for the treatment of 53 olfactory neuroblastomas

“…The shortcomings of these classifications may be due to their initial description based on a small number of patients, patients without an MRI or at a time when an MRI was too recent to allow accurate staging of intracranial or intraorbital extension. Even with CT and MRI, accurate staging remains difficult . Jankowski et al recently proposed a new prognostic classification based on the behavior of ONB inside and outside the olfactory cleft, which still remains to be validated.…”

“…Even with CT and MRI, accurate staging remains difficult. 23,24 Jankowski et al 25 recently proposed a new prognostic classification based on the behavior of ONB inside and outside the olfactory cleft, which still remains to be validated. In the metaanalysis by Fu et al, 15 as in our study, the Hyams grade was not correlated with OS, DFS, or tumor status.…”

Clinical utility of apparent diffusion coefficient and diffusion‐weighted magnetic resonance imaging for resectability assessment of head and neck tumors with skull base invasion

“…Thus, few studies have examined the relationship between pathological spread and diagnostic images in SBTs. Mortuaire et al suggested that CT/magnetic resonance imaging (MRI) mapping cannot replace the accurate assessment of pathological tumor extension during surgery in sinonasal malignancies 4 . Although Bier et al described the low occurrence of false positives of dural enhancement by eMRI in carcinomatous meningeosis, 5 no conclusion has been reached about the accuracy of the pathological progression and CT/MRI findings in SBTs.…”

Data Set for the Reporting of Carcinomas of the Nasal Cavity and Paranasal Sinuses: Explanations and Recommendations of the Guidelines From the International Collaboration on Cancer Reporting

“…It is worth noting that a number of studies have reported significant discrepancies between clinical and pathological T categorization. 52,53 In particular, imaging is not sufficiently accurate in the assessment of invasion of the orbit, the skull base, and frontal or sphenoid sinuses. 52 Thus, careful histopathologic assessment is essential for a correct staging of sinonasal carcinomas.…”

“…52,53 In particular, imaging is not sufficiently accurate in the assessment of invasion of the orbit, the skull base, and frontal or sphenoid sinuses. 52 Thus, careful histopathologic assessment is essential for a correct staging of sinonasal carcinomas. Finally, when neck lymph node dissections are included as part of the surgical specimen, a separate linked data set for Nodal Excisions and Neck Dissection Specimens for Head & Neck Tumours has to be completed.…”
