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.
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).
Percentage change of primary tumor on 18F-FDG PET/CT as a prognostic factor for invasive ductal breast cancer with axillary lymph node metastasis: Comparison with MRI.
We presented a case of a 73-year-old man with histologically proven IgG4-related chronic sclerosing sialadenitis, unilateral localized form, on whole-body F-FDG PET/CT images that mimicked submandibular carcinoma with lymph node metastasis.
<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.
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.
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.
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.
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.
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.
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.
We determined the value of F-fluorodeoxyglucose positron-emission tomography/computed tomography (FDG PET/CT) for the assessment of preoperative lymph node metastases in patients with esophageal cancer.
The sensitivity, specificity, overall accuracy, PPV, and NPV of <sup>18</sup>F-FDG PET/CT for detecting lymph node metastasis from pediatric neuroblastoma were 100, 98.7, 98.9, 95.0, and 100%, respectively, and those for detecting bone metastasis were 90.7, 73.1, 80.3, 70.1, and 91.9%, respectively.
