Background: There is growing evidence that long non-coding RNA long iatrogenic non-protein-coding RNA p53-induced transcript (LINC-PINT) is highly expressed in cancer tissue and is associated with the prognosis of cancer patients. The present study systematically analyzed the prognostic significance of LINC-PINT expression in cancer patients. We aimed to reveal the association between LINC-PINT expression and survival in cancer patients.

Article Synopsis
  • - The study investigates the role of tumor necrosis factor receptor 2 (TNFR2) in cancer progression and its correlation with the prognosis of various cancers including lung, breast, and colorectal cancers.
  • - A meta-analysis of nine studies, including 2,229 patients, found that high TNFR2 expression is significantly linked to poorer overall and disease-free survival rates, as well as higher tumor grade, stage, and clinical stage.
  • - The results suggest that TNFR2 could serve as an important prognostic factor for patients with cancer, indicating worse outcomes when expressed at high levels.

Background: Atherosclerotic cardiovascular disease (ASCVD) is a major health concern, and lipoprotein(a) (Lp(a)) is an independent risk factor. However, there is limited evidence regarding Lp(a) and the risk of ASCVD in Asian populations. This study aimed to assess the predictive value of changes in coronary artery calcification (CAC) for ASCVD risk associated with Lp(a) level.

Background: Diffuse large B-cell lymphomas are the most common type of non-Hodgkin lymphoma. Because cutaneous lymphomas predominantly originate from the T cells, primary cutaneous diffuse large B-cell lymphomas are considered a rare subtype of extranodal diffuse large B-cell lymphomas that commonly involve the subcutaneous tissues of the trunk and extremities. To date, only a single case of facial primary cutaneous diffuse large B-cell lymphoma has been reported in the literature.

Background: Myoferlin is a multifunctional protein expressed in various normal and cancer cells, with novel oncogenic roles being newly discovered. Recently, correlations have been found between myoferlin expression and unfavorable prognosis in various carcinomas. This study investigated the prognostic role of myoferlin expression in papillary thyroid carcinoma (PTC), specifically that associated with nodal metastasis.

Background: Recent studies have shown that nicotinamide adenosine dinucleotide phosphate oxidase 4 (NOX4) is related to cancer development, proliferation, invasion, epithelial-to-mesenchymal transition, and metastasis. The prognostic value of NOX4 expression although has been reported in various cancers, it remains unclear as several studies have reported conflicting results. Therefore, the purpose of this study was to systematically investigate the prognostic value of NOX4 expression in cancer patients.

Background: Recent studies have shown that CD90 has an important role in cancer development. Moreover, CD90 is reportedly associated with cancer progression, metastasis, and poor prognosis. Thus, we performed this meta-analysis to investigate the prognostic and clinicopathological value of CD90 expression in patients with cancer.

Background: The expression of S100A8 and S100A9 is found to be related with the survival of cancer patients, but the results and information regarding their prognostic significance are inconsistent in literature. This study, therefore, aimed to perform a comprehensive meta-analysis and determine the prognostic significance of S100A8 and S100A9 expression in patients with cancer.

Methods: Data were collected by performing a literature search on the PubMed, Cochrane library, and Scopus databases.

Background: CXC chemokine receptor 3 (CXCR3) plays a critical role in tumorigenesis, and CXCR3 expression is associated with prognosis in many cancers. Recently, CXCR3 expression is recognized as a potential prognostic factor for patients with gastric cancer. In this study, we analyzed the prognostic significance of CXCR3 expression in gastric cancer.

Ectopic adrenal gland in the ovary is very rare case, and even more rarer in older women. We reported a case of ectopic adrenal tissue as an incidental finding in left ovary from a 68-year-old woman. She presented with bearing down sensation due to uterine prolapse for 5 years.

Lineage tracing in mice indicates that LGR5 is an adult stem cell marker in multiple organs, such as the intestine, stomach, hair follicles, ovary, and mammary glands. Despite many studies exploring the presence of LGR5 cells in human tissues, little is known about its expression profile in either human mammary tissue or pathological lesions. In this study we aim to investigate LGR5 expression in normal, benign, and malignant lesions of the human breast using RNA in situ hybridization.

Article Synopsis
  • A study looked at a protein called CD9 to see how it affects cancer progression and patient survival.
  • They analyzed data from 17 studies with over 3,400 cancer patients and found that higher CD9 levels were linked to better survival rates.
  • The results suggest that checking CD9 levels could help doctors understand how well a cancer patient might do over time.

Background: Osteocalcin is known to regulate energy metabolism. Recently, metabolic syndrome (MetS) has been found to be associated with reduced levels of osteocalcin in men, as well as in postmenopausal women. The aim of this study was to investigate the association between serum osteocalcin and MetS in premenopausal women, compared with that in postmenopausal women.

Cancer stem cells (CSCs) are believed to be responsible for tumor growth, invasion, and metastasis. Submucosal invasion, which greatly enhances metastasis risk, is a critical step in gastric cancer (GC) progression. To identify stem cell-related markers associated with submucosal invasion and lymph node (LN) metastasis in GCs, we investigated the expression of candidate CSC markers (CD133, CD44, and ALDH1A) and intestinal stem cell (ISC) markers (EPHB2, OLFM4, and LGR5) in early GCs that manifested submucosal invasion.

Background: Hepatoma-derived growth factor (HDGF) promotes cancer progression and metastasis by interacting with vascular endothelial growth factor, thereby inducing epithelial-to-mesenchymal transition and angiogenesis. Recent studies have correlated increased HDGF levels with poor prognosis in various malignancies, including lung cancer. This meta-analysis systematically assessed the prognostic significance of HDGF expression in patients with non-small cell lung cancer (NSCLC).

Background: Programmed death-ligand 1 (PD-L1) is one of the immune checkpoint proteins, and plays an important role in the progression and microenvironment of cancer. PD-L1 expression has been associated with poor survival in many cancers. Several studies have also shown an association between PD-L1 expression and the prognosis of patients with thymic epithelial tumors (TETs).

Background: CD63 has been described as a key factor in extracellular vesicle production and endosomal cargo sorting, and there have been certain reports suggesting an association between CD63 expression and survival in patients with tumors including gastric, colon and lung cancer. However, the prognostic value of CD63 expression remains contradictory. Hence, we performed this meta-analysis to assess the prognostic value of CD63 expression in solid tumors.
