The pathology archives of 11 institutions from 4 countries were retrospectively searched to identify all salivary gland fine-needle aspiration (FNA) biopsies with a differential or definitive diagnosis of PA or WT and all resection specimens with a diagnosis of PA or WT; only paired cases were included. All FNA diagnoses were retrospectively classified according to the MSRSGC.
A total of 1250 cases met the inclusion criteria, and they included 898 PA cases and 352 WT cases. The ROM in the benign neoplasm category was 3.0% and 1.3% for cases with a differential or definitive diagnosis of PA and WT, respectively. The ROM in the salivary gland neoplasm with uncertain malignant potential (SUMP) category was 2.7% and 18.8% for PA and WT, respectively (P = .0277). The diagnostic accuracy for PA and WT was 95.1% and 96.1%, respectively.
The diagnostic accuracy for PA and WT on FNA is high. Furthermore, these findings highlight the difference in the ROMs associated with 2 specific differential diagnoses in the SUMP category: basaloid neoplasms and oncocytoid neoplasms.
回顾性检索了来自4个国家的11个机构的病理学档案,以确定所有唾液腺细针穿刺(FNA)活检与PA或WT的鉴别或明确诊断,以及所有切除标本与PA或WT的诊断;仅包括配对病例。所有FNA诊断均根据MSRSGC进行回顾性分类。
共有1250例符合纳入标准,其中包括898例PA病例和352例WT病例。对于PA和WT的鉴别或明确诊断的病例,良性肿瘤类别的ROM为3.0%和1.3%。分别。对于PA和WT,具有不确定恶性潜能(SUMP)类别的唾液腺肿瘤中的ROM分别为2.7%和18.8%,分别为(P=0.0277)。PA和WT的诊断准确率分别为95.1%和96.1%,分别。
FNA上的PA和WT的诊断准确性很高。此外,这些发现强调了与SUMP类别中2种特定鉴别诊断相关的ROM的差异:基底细胞样肿瘤和肿瘤细胞样肿瘤.
