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...
Papillary thyroid carcinoma, Neck lymph node, Lymph node metastasis, Tumor diameterLittle is known about the pathological characteristics of metastatic and nonmetastatic lymph nodes (LNs) in papillary thyroid carcinoma (PTC). The aim of this study was to elucidate the pathological characteristics of ...
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 ...
enhancement of the lymphomatous nodes was significantly lower than that of the control group in the time interval from 40 s to 180 s after injection.The enhancement pattern previously suggested from studies of retroperitoneal lymph nodes was confirmed in this prospective study of cervical nodes. ...
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 ...
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...
1,2,9 Any or all of these characteristics warrant consideration of fine needle aspiration (FNA) or biopsy (Fig. 2). Sign in to download hi-res image Fig. 2. Lymph node metastasis from papillary thyroid carcinoma on ultrasound. Necrosing lymph nodes tend to become increasingly hypoechoic and...
3 These characteristics parallel those of non—small cell lung cancer (NSCLC), where pembrolizumab has shown activity in a subgroup of patients.4 Additionally, HNSCCs are accessible for tissue biopsies, enabling powerful correlative studies that can result in a distinct advantage in clinical trial ...

1/59 (1.6%) , 28 patients with negative lymph nodes and 31 patients without lymph node sampling, developed distant metastasis. Clinical factors associated with metastasis were young age (mean 35 years, p=0.02), female gender, and carotid body location, although the age is the only parameter ...
