<sup>18</sup>F-FDG PET/CT identified 19 patients (sensitivity: 67.9%) in 28 patients with lymph node metastases, and 22 patients (specificity: 88.0%) in 25 patients without lymph node metastases, with an accuracy of 77.4%.
When the combined diagnosis of FDG PET/CT and SNB was made, the sensitivity and specificity were 84.2% and 82.1%, respectively.SNB was more useful for detecting lymph node metastasis than FDG PET/CT, especially in patients with small metastatic lymph nodes.
FDG uptake in the lymph nodes was detected in 21 patients (17.9%), and its sensitivity and specificity for lymph node metastasis were 22.7 and 90.5%, respectively.
Reasons for false negative findings were low <sup>18</sup>F-FDG uptake of local recurrence in one patient and low <sup>18</sup>F-FDG uptake of subcentimetric inguinal lymph node metastases.
Prediction of ultrasound guided fine needle aspiration cytology results by FDG PET-CT for lymph node metastases in head and neck squamous cell carcinoma patients.
Thirteen patients (30 lymph nodes) and 16 patients (105 lymph nodes) were suspected to have lymph node metastases based on the RGD and FDG scans, respectively.
The aim of this study was to investigate the capability of F-FDG PET/computed tomography (CT)-related metabolic parameters to predict lymph node metastasis (LNM) and occult lymph node metastasis (OLNM) in patients with esophageal squamous cell carcinoma (ESCC).
Predictive value of primary tumor parameters using <sup>18</sup>F-FDG PET/CT for occult lymph node metastasis in breast cancer with clinically negative axillary lymph node.
Preoperative ¹⁸F-FDG PET/CT imaging is useful in predicting the LNM of EC and may help guide pelvic lymphadenectomy to avoid unnecessary pelvic lymphadenectomy in EC patients with low-risk stratification.
Systematic review and meta-analysis of the accuracy of 18F-FDG PET/CT for detection of regional lymph node metastasis in esophageal squamous cell carcinoma.
Our analysis showed a relative increase in the expression of E2F6 in gastric adenocarcinoma with no lymph node metastasis (χ <sup>2</sup>, P = 0.04 and OR, P = 0.08), while overexpression of RhoA and SMUG1 was found more often in the diffuse subtype of gastric adenocarcinoma as compared to the intestinal subtype (χ <sup>2</sup>, P = 0.05, OR, P = 0.08 and χ <sup>2</sup>, P = 0.001, OR, P = 0.009, respectively).
The diagnostic accuracy for predicting pelvic node metastases for FDG PET/CT and SNB compared with the ultimate histologic status was analyzed.Among 96 hemi-pelvises (HPs) in 48 patients, pelvic lymph node metastases were obtained in 12 HPs.
The purpose of this study was to investigate if FDG uptake metrics in primary tumor and lymph node metastases in patients with oropharyngeal squamous cell carcinoma (OPSCC) has a prognostic value beyond UICC8 staging in a multiple endpoint model.
In three of the four studies, cervical ultrasonography did not detect cervical lymph node metastases in addition to a negative finding on F-FDG PET/CT or standalone F-FDG PET and CT.
To investigate whether a 18F-FDG PET/CT (PET/CT)-based diagnostic strategy adds decisive new information compared to conventional imaging in the evaluation of salivary gland tumours and the detection of cervical lymph node metastases, distant metastases, and synchronous cancer in patients with salivary gland carcinoma.
<sup>18</sup>F-FDG PET and PET/CT both have excellent diagnostic performance for detecting lymph node metastasis, including PLN and PALN metastasis, in patients with endometrial cancer preoperatively.
We used normal mixture modeling to explore FDG-PET standardized uptake value (SUV) distributions and tested for associations between glucose uptake and histological differentiation, risk of lymph node metastasis, and survival.
