High-grade gliomas are the most threatening brain tumors due to aggressive proliferation and poor prognosis. Thus, utilizing genetic glioma biomarkers to forecast prognosis and guide clinical management is crucial. Procollagen-lysine, 2-oxoglutarate 5-dioxygenase 3 (PLOD3) modulates cancer progression and metastasis. However, its detailed function in cancer remains largely uninvestigated. PLOD3 expression was evaluated with real-time PCR in glioblastoma (GBM) cell lines and by Gene Expression Omnibus dataset analysis and immunohistochemistry of glioma tissues...

Angiosarcoma is a vascular malignancy associated with a poor prognosis and chemotherapy resistance. The tumor immune microenvironment of angiosarcoma has not been characterized. We investigated the expression of programmed death-ligand 1 (PD-L1) and programmed death 1 (PD-1) in angiosarcoma and correlated these findings with vascular endothelial growth factor (VEGF)-related gene expression and survival. Using archived formalin-fixed paraffin-embedded tissues of primary and metastatic angiosarcoma specimens, we characterized the immunohistochemical (IHC) expression of PD-L1 and PD-1...

Cervical cancer constitutes a leading cause of morbidity and cancer deaths in women throughout the world. Approximately two thirds of the patients are diagnosed with locally advanced cervical cancer, showing disappointing survival rates despite correct multidisciplinary management. Metastatic disease implies a poor prognosis itself since diagnosis. Platinum-based chemotherapy has been the backbone treatment of metastatic cervical cancer for years with no major outstanding improvements on survival. The addition of new molecules, such as antiangiogenic agents, dramatically changed the treatment of this disease...

The inflammatory chemokine (C-C motif) ligand 4 (CCL4) plays an important role in the pathogenesis and progression of cancer. In particular, higher serum CCL4 levels in patients with oral squamous cell carcinoma (OSCC) are associated with a more advanced stage of disease. OSCC accounts for approximately 95% of oral cancer in Taiwan and has a poor prognosis, due to aggressive local invasion and metastasis, leading to recurrence. OSCC spreads preferentially through lymphatic vessels and has the propensity to metastasize to the cervical lymph nodes even in the early stage of disease...

Clinical outcome prediction is major concern to patients with cancer. Various molecular markers in various carcinomas have been identified in the past few decades. However, accurate predictors in chondrosarcoma have not been developed, even though chondrosarcoma is the second most common primary bone tumour. Chondrosarcoma is the cartilage-forming malignancy and shows a wide spectrum of clinicopathological behaviours. The majority of chondrosarcoma grows slowly and rarely metastasises, and adequate surgery leads to a good prognosis...

Concurrent with an expansion in the number of agents available for the treatment of advanced CRC, there has been an increase in our understanding of selection biomarkers to optimize the management of patients with this disease. For CRC patients being considered for anti-EGFR therapy, expanded RAS testing is the standard of care to determine the subset of patients who can benefit from cetuximab or panitumumab in conjunction with chemotherapy. A small fraction of patients have HER2 amplification where emerging data suggest treatment with drugs targeting this alteration...

The vascular endothelial growth factor regulates angiogenesis that is increased in glioma. VEGF polymorphisms are thought to modulate vascular endothelial growth factor plasma levels and therefore may be implicated in glioma risk. We aimed to clarify the role of VEGF and von Willebrand factor polymorphisms in glioma susceptibility and prognosis. A case-control study of 126 glioma patients and 180 cancer-free controls was performed. Using Sequenom MassARRAY platform, 11 VEGF and 1 VWF polymorphisms were genotyped...

Gallbladder cancer (GBC) is the most common malignant tumor of the biliary track system. Epithelial-mesenchymal transition (EMT) plays a vital role in the process of tumor metastasis. Mesenchymal-like cells can serve as a source of cancer stem cells (CSCs), which can confer the EMT phenotype. Placental growth factor (PLGF) belongs to the VEGF family and plays a vital role in cancer. However, the underlying molecular mechanisms about the influence of PLGF on EMT in GBC remain unknown. Here we show that PLGF expression levels were higher in GBC tissues than in normal adjacent tissues (NATs) and were associated with poor prognosis in GBC patients...

Post-MI depression is a critical clinical problem, the comorbidity of which complicates depression treatment and worsens cardiovascular outcomes. However, which antidepressant is the best to lower the risk of cardiovascular events in persons with depression was still unknown. Recently, it has been proposed that the activation of ALDH2 by Alda-1 can effectively reduce depressive-like behaviors and improve the prognosis of coronary heart disease. In the present study, we investigated the effect of Alda-1 on the expression of VEGF in the hippocampus of a rat model with post-MI depression, as well as the potential treatment mechanism...

Malignant melanoma (MM) is caused by melanophore cancerization in tissue pigmentation regions, leading to skin, mucous membrane, eye and central nervous system carcinogenesis. The incidence of MM has increased in previous years, and it has become the primary cause of skin cancer‑associated mortality in developed countries. MM is characterized as highly malignant and readily metastasized, and has a poor prognosis. Targeting angiogenesis is an important method for MM treatment. As an important proangiogenic factor in tumor growth and metastasis, vascular endothelial growth factor (VEGF) can promote neovascularization and increase vascular permeability...

Pancreatic ductal adenocarcinoma (PDAC) has poor prognosis and high mortality rate. Inhibitor of differentiation-1 (ID-1) overexpression has already been reported to be associated with low survival, but the detailed roles of ID-1 in PDAC are unclear. As an ID-1 inhibitor, 2-methoxyestradiol (2-ME) has been shown effective in the anti-tumor therapies, but its effect on PDAC is unknown. In this study, ID-1 overexpression and knockdown stable SW1990 cells were used to examine proliferation, migration and invasion abilities...

The most widely accepted treatment for cutaneous angiosarcoma (CAS) is wide local excision and postoperative radiation to decrease the risk of recurrence. Positive surgical margins and large tumors (T2, >5 cm) are known to be associated with poor prognosis. Moreover, T2 tumors are known to be associated with positive surgical margins. According to previous reports, the majority of CAS patients in Japan had T2 tumors, whereas less than half of the patients in the studies from western countries did so. Consequently, the reported 5-year overall survival of Japanese CAS patients without distant metastasis was only 9%, lower than that for stage-IV melanoma...

Introduction: The introduction of targeted therapies in renal cell carcinoma has significantly improved its prognosis and treatment outcomes in recent years. Such treatment options are targeted therapies of the vascular endothelial growth factor (VEGF) pathway and the mammalian target of the rapamycin pathway. With the use of tyrosine kinase inhibitors (TKIs) and mammalian target of the rapamycin inhibitors, overall survival has increased up to 2 years. In Turkey, due to applicable reimbursement conditions for patients with metastatic renal cell carcinoma (mRCC), interferon use is mandated as a first-line treatment, thus providing information on the use of everolimus only after initial interferon and second-line VEGF-targeted treatments such as VEGF-TKI...

Accumulating evidence suggests that a unique set of receptor tyrosine kinases, known as discoidin domain receptors (DDRs), plays a role in cancer progression by interacting with the surrounding collagen matrix. In this study, we investigated the expression and role of DDR1 in human gastric cancer metastasis. Proliferation, migration, invasion, and tube formation assays were conducted in DDR1-expressing MKN74 gastric cancer cells and corresponding DDR1-silenced cells. The effects of DDR1 on tumor growth and metastasis were examined in orthotopically implanted and experimental liver metastasis models in nude mice...

BACKGROUND: Patients suffering from squamous cell carcinoma of the larynx (LSCC) with lymphatic metastasis have a relatively poor prognosis and often require radical therapeutic management. The mechanisms which drive metastasis to the lymph nodes are largely unknown but may be promoted by a pro-angiogenic tumor microenvironment. In this study, we examined whether the number of microvessels and the expression level of vascular endothelial growth factor (VEGF) in the primary tumor are correlated with the degree of lymph node metastasis (N-stage), tumor staging (T) and survival time in LSCC patients...
