1.Advances in imaging and pathological research on extramural vascular invasion of rectal cancer
Chinese Journal of Digestive Surgery 2016;15(8):847-850
Extramural vascular invasion(EMVI)was defined as the presence of tumor cells within an endotheliumlined vessel beyond the muscularis propria.High-resolution MRI had 100%sensitivity and 89%specificity in identification of large(caliber greater than 3 mm)EMVI with histopathology as reference.EMVI detected by both histopathology and MRI was significantly associated with local recurrence,distance metastasis and tumor-related death in rectal cancer,which was also identified as an independent prognostic factor for 3-year tumor-free survival and overall survival.EMVI could be used as one of the risk factors,which would allow stratification of patients with rectal cancer to receive neoadjuvant chemoradiotherapy(neoCRT).Moreover,EMVI detected by high-resolution MRI was identified as an independent predictor for response to neoCRT.Tumor regression grading scale defined by high-resolution MRI could be used to evaluate EMVI regression after neoCRT.

Metabolic syndrome (MS) and breast cancer are common diseases of women. Triple negative breast cancer (TNBCs) is one type of breast cancer, which is of much attention in recent years. Important components of MS include central obesity, high blood sugar, high triglycerides and low level of high-density lipoprotein (HDL-C), which increased the inci-dence risk of TNBCs. Common biomarkers of MS including insulin, adiponectin and leptin play an important role in the oc-currence and development of breast cancer, especially TNBCs. Insulin-like growth factor-IImRNA binding protein 3 (IMP3, an oncofetal protein) may be TNBCs’new invasive cancer biomarkers. In this paper, the research progress on the relation-ship between MS and TNBCs is reviewed.
