Lymph node counting

Zhuowei Xue, Xiaolu Zhu, Yincheng Teng
Epithelial ovarian cancer (EOC) is one of the leading causes of cancer‑associated mortality in women. At present, the overall 5‑year survival rate of patients with EOC remains poor despite advancements in diagnosis and treatment. Long non‑coding RNAs (lncRNAs) have attracted increasing attention in recent years for their extensive roles in tumorigenesis and cancer development. The lncRNA cancer susceptibility candidate 2 (CASC2) was originally identified as a downregulated gene in endometrial cancer, and subsequent studies revealed that CASC2 was able to act as a tumor suppressor gene in various types of cancer...

Older melanoma patients have lower rates of sentinel lymph node (LN) metastases yet paradoxically have inferior survival. Patient age correlated with an inability to retain Technetium radiotracer during sentinel LN biopsy in over 1000 patients, and high technecium counts correlated to better survival. We hypothesized that loss of integrity in the lymphatic vasculature due to ECM degradation might play a role. We have implicated HAPLN1 in age-dependent ECM degradation in the dermis. Here we queried whether HAPLN1 could be altered in the lymphatic ECM...

Circulating tumour cells (CTCs) originating from a primary tumour, lymph nodes and distant metastases hold great potential for liquid biopsies by providing a molecular fingerprint for disease dissemination and its temporal evolution through the course of disease management. CTC enumeration, classically defined on the basis of surface expression of Epithelial Cell Adhesion Molecule (EpCAM) and absence of the pan-leukocyte marker CD45, has been shown to correlate with clinical outcome. However, existing approaches introduce bias into the subsets of captured CTCs, which may exclude biologically and clinically relevant subpopulations...

A 9-year-old spayed female Curly Coated Retriever was referred for evaluation of generalized peripheral lymphadenomegaly. The dog was clinically healthy on presentation with no anomalies detected on complete blood count, serum biochemistry, urinalysis, or three-view thoracic radiographs. Fine-needle aspiration (FNA) and cytology of the peripheral lymph nodes were consistent with lymphoma with an intermediate-sized lymphoid population. Flow cytometry of peripheral lymph nodes was consistent with a homogeneous population of CD4+ T cells that had lost expression of the pan-leukocyte antigen CD45...
