Purpose: Papillary thyroid cancer (PTC) has grown rapidly in prevalence over the past few decades, and central neck lymph node metastasis (CNLNM) is associated with poor prognoses. However, whether to carry out preventive central neck lymph node dissection (CNLND) is still...
Stern et al13 present a series of 85 patients with SCC of the maxillary sinus and conclude that there is the indication for systematic elective irradiation of the cervical lymph nodes during the course of postoperative radiotherapy for all patients with squamous cell carcinoma, except for those ...
Lymph nodes.An enlarged cervical lymph node is the most commonly encountered neck lump. The role of ultrasound is to differentiate pathological nodes (e.g., metastases, lymphoma, tuberculous lymphadenitis) from normal/reactive nodes (Figure 1). Different ultrasound criteria have been established to d...
The most commonly used characteristics are size, irregularity, necrosis, cystic degeneration, spherical shape, and clustering lymph nodes [6, 7]. However, enlargement may be observed in reactive lymph nodes, whereas malignant lymph nodes may maintain normal morphology [8]. A meta-analysis found a...
General study characteristics All 106 studies that utilized structured datasets were published between 2016 and 2022 with more studies in 2021 than other years (Fig.2). Majority of the studies were conducted in China (26.4%) and the USA (16%) with only 5.7% of the studies conducted in India...
Across these studies, clinical characteristics are being used to further classify risk for those with HPV-positive disease, such as tumor size, margins following surgery, extracapsular spread (ECS), and lymph node involvement. The phase 2 NRG-HN002 study (NCT02254278)4 specifically examined a 60...
In conclusion, histopathological characteristics can be a predictor of the extent of LNM. Bilateral and multifocal PTC indicate that the disease has probably spread to more lymph nodes. So, patients should undergo careful evaluations for LNM when they have multifocal or bilateral PTC. Also, Lymph ...

Evaluation of metastatic lymph nodes in head and neck cancer: a comparative study between palpation, sonography, ultrasound-guided fine needle aspiration cytology and computed tomography. Acta Clin Belg 2006;61:236-241. PubMed CAS Google Scholar Saad RS, Takei H, Lipscomb J, Ruiz B. Nodular ...
Lymph nodes with suspected involvement were diagnosed on the basis of ultrasound characteristics of metastatic lymph nodes of papillary thyroid cancer, such as the presence of calcification, cystic change, loss of an echogenic fatty hilum, hyperechogenicity, round shape and abnormal vascularity on color...
