Abstract

PURPOSE

The purpose was to test whether patient's primary malignancy type and presence of F-18-fluorodeoxyglucose (FDG)-avid cervical lymph node(s) are predictors of pathologic outcome of incidental focal FDG-avid parotid lesions.

BASIC PROCEDURES

A retrospective cohort study of pathologically proven incidental cases was performed.

MAIN FINDINGS

Focal parotid FDG uptake in the setting of head and neck cancer/melanoma [odds ratio (OR)=24.6, P<.01], lymphoma (OR=7.2, P=.02), or FDG-avid cervical lymph node(s) (OR=3.6, P=.07) has a higher odds of representing metastases. No malignant primary parotid tumors were incidentally discovered.

PRINCIPAL CONCLUSIONS

In patients with head and neck cancer/melanoma, lymphoma, or FDG-avid cervical lymph node(s), there were higher odds that focal parotid FDG uptake was a metastasis.

摘要

目的

旨在测试患者的原发性恶性肿瘤类型以及F-18氟脱氧葡萄糖(FDG)摄取阳性的颈部淋巴结是否为偶然发现的局灶性FDG摄取阳性腮腺病变病理结果的预测因素。

基本程序

对经病理证实的偶然病例进行回顾性队列研究。

主要发现

在头颈部癌/黑色素瘤[比值比(OR)=24.6,P<0.01]、淋巴瘤(OR=7.2,P=0.02)或FDG摄取阳性的颈部淋巴结(OR=3.6,P=0.07)的情况下,腮腺局灶性FDG摄取更有可能代表转移瘤。未偶然发现原发性腮腺恶性肿瘤。

主要结论

在患有头颈部癌/黑色素瘤、淋巴瘤或FDG摄取阳性的颈部淋巴结的患者中,腮腺局灶性FDG摄取更有可能是转移瘤。
