“…The presence or absence of lymph node metastasis was evaluated using ultrasonography (US). Lymph nodes measuring 7 mm or more in minimum diameter, with a minimum diameter/maximum diameter ratio of 0.5 or more, were regarded as metastatic [9]. According to this classification, lymph node metastasis was assessed as N0 in 56 patients, N1 in 11, and N2 in 10.…”

“…After making a preoperative diagnosis using specific diagnostic criteria for lymph node metastasis [9], we perform (M)RND in clinically N+-suspected patients and histological high-grade carcinoma patients, and SND (level II-IV and the superior area of level V) in N0 patients with low-to intermediate-grade carcinoma. In this study, we investigated the preoperative/ postoperative assessment of lymph node metastasis and histological grade in 77 patients with primary parotid carcinoma who underwent initial treatment in our department, and reviewed the indications for and extent of END.…”

Lymph node metastasis was detected in 27 of 71 patients who underwent neck dissection. Node metastasis was detected in 19 (61.3%) of 31 patients in whom high-grade malignancy was suggested and in 8 (22.9%) of 35 patients in whom intermediate-grade malignancy was suggested preoperatively. There was no metastasis in any of the five patients in whom low-grade malignancy was suggested. Occult metastasis was noted in 8 of 51 patients. The rate at which the histological grade was accurately diagnosed before surgery was low, especially in patients with low-grade malignancy.

“…Cervical lymph nodes visualized on US were considered to be metastatic if they showed the following criteria: a short axis diameter > 7 mm, the long-to-short axis ratio < 2, absence of an echogenic hilum, and the absence of normal hilar blood flow and/or the presence of abnormal peripheral blood flow on color Doppler imaging [11][12][13]. 3.…”

CT, MR, US, 18F-FDG PET/CT, and their combined use for the assessment of cervical lymph node metastases in squamous cell carcinoma of the head and neck

The purpose of this retrospective study was to compare the diagnostic value of four different imaging methods-computed tomography (CT), magnetic resonance (MR) imaging, ultrasonography (US), and (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT-and their combined use for preoperative detection of cervical nodal metastases in head and neck squamous cell carcinoma (SCC). Sixty-seven patients (58 men and 9 women; mean age, 60.1 years) with head and neck SCCs underwent CT, MR, US, and PET/CT before surgery. First, each study was reviewed separately for the presence of nodal metastases. Then, the value of combined images was assessed based on a confidence rating score for each modality assigned by observers. These results were verified, on a level-by-level basis, with histopathologic findings. Histopathologic examination revealed nodal metastases in 74 of 402 nodal levels. The sensitivity, specificity, and accuracy were 77.0%, 99.4%, and 95.3% for CT and MR; 78.4%, 98.5%, and 94.8% for US; and 81.1%, 98.2%, and 95.0% for PET/CT, respectively. The comparison of these modalities showed no statistically significant difference among them (p > 0.05). The combination of CT, MR, US, and PET/CT improved sensitivity (86.5%), without loss of specificity (99.4%) and accuracy (97.0%), although the difference failed to reach statistical significance.
