Evaluation and localization of lymphatic drainage and sentinel lymph nodes in patients with head and neck melanomas by hybrid SPECT/CT lymphoscintigraphic ... In patients with head and neck tumors, preoperative lymphoscintigraphy can be used to map lymphatic drainage patterns and identify sentinel lymp...
on the inner sides of the elbows and behind the knees can be as small as few millimeters, while those in the groin can reach 1.5 centimeters[4]. In some healthy older children, the lymph nodes in the neck and armpits can be palpated, while in healthy adults, except in ...
In the chronic stage of brucellosis, symptoms may persist or recur. Both acute and chronic infections in humans can have a significant impact on infected individuals and their families due to the significant loss of workdays and the resulting socioeconomic impact (WHO, Estimates of the global bur...
Currently accepted immune checkpoint inhibitors resistance mechanisms.Resistance to currently used immune checkpoint inhibitors, namely anti-PD1, anti-PD-L1 and anti-CTLA-4 therapeutic antibodies, has been associated with the lack of effective tumour T cell infiltration. This could be due to lack of ...

a 20-gene signature of CD8+exhausted T (Tex) cells derived from lymph nodes could be used to predict LNM, and targeting the HLA-E-KLRC1/KLRC2 signaling pathway may present new clinical treatment opportunities for GC [58]. Cancer stem cells (CSCs) are crucial for cancer treatment and progno...
Diagnostic value of dual-energy CT imaging for cervical lymph nodes metastasis in the patients with papillary thyroid cancer[J]. China Oncol, 2018, 28(7): 497−504. DOI: 10.19401/j.cnki.1007-3639.2018.07.004. [7] Zhuo SQ, Sun JY, Chang JY, et al. Dual-source dual-energy thin-...
Forty-seven cases of thyroid cancer and 44 cases of large goiters were analysed. Surgeon read additional signs such as obliterated fat plane between goiter and subcutaneous plane&59; level I lymph nodes&59; bilateral cervical lymphadenopathy, internal jugular vein thrombus, and pharyngeal invasion ...
Asegmentation mapis a partition of the plane. Each region represents an object or a specific area on the image. Consider a random fieldY= (ys)s∈Λ, whereys∈S. The likelihood termP(Y|X) model thegray level distributionof the pixels belonging to a given class or region. For example, ...
In every case there was emperipolesis in a subset of the histiocytes (Figures 1–3), although emperipolesis was much less obvious in extranodal sites, particularly when associated with dense fibrosis (Figure 1b). Involved lymph nodes were enlarged with a variably thick- ened, fibrotic ...
