Anti-Prokineticin1 Suppresses Liver Metastatic Tumors in a Mouse Model of Colorectal Cancer with Liver Metastasis.

Multidisciplinary treatment for colorectal cancer (CRC) has undergone significant advances, and molecularly targeted drugs have substantially improved patient prognosis. However, one problem with current molecularly targeted therapeutics is that they must be used in combination with anticancer agents. New molecular targeted therapies that can be used alone are needed.

18F-Fluorodeoxyglucose Positron Emission Tomography/Magnetic Resonance Imaging-Defined Extramural Venous Invasion Predicts Distant Metastasis and Reflects Strong Tumor Invasiveness in Rectal Cancer.

Introduction: Extramural vascular invasion in patients with rectal cancer is a poor prognostic factor associated with distant metastasis; thus, accurate preoperative diagnosis is important. However, the accurate detection of extramural vascular invasion using magnetic resonance imaging (MRI) is difficult, and an improved diagnostic modality is required. In addition, the factors involved in the formation of extramural venous invasion (EMVI) remain unclear.

Oxidative Stress as a Biomarker for Predicting the Prognosis of Patients with Colorectal Cancer.

Introduction: Excess oxidative stress is generated by inflammation and cancer, and it is involved in the development and metastasis of colorectal cancer. However, there are few reports on the relationship between blood oxidative stress and prognosis. This study examined the usefulness of derivatives of reactive oxygen metabolites (d-ROMs), a measure of oxidative stress, and the neutrophil-to-lymphocyte ratio (NLR), an inflammatory marker, as prognostic markers in colorectal cancer.
