US-guided Diffuse Optical Tomography: Clinicopathological Features Affect Total Hemoglobin Concentration in Breast Cancer

摘要

PURPOSE:To investigate breast cancers total hemoglobin concentration (THC) characteristics and its association with clinical pathologic findings.MATERIALS AND METHODS:The study was approved by the institutional review board and all patients provided written informed consent. 447 breast cancer patients, totally 455 lesions were included in our study. The size and THC of breast lesions were measured by conventional ultrasound (US) and US-guided Diffuse Optical Tomography (DOT) 1–2?days before surgery. Clinical and pathology information of patients was collected.RESULT:The average THC values of ER- or PR- lesions were significantly higher than the positive ones (P?=?.005 andP?=?.01,respectively); The average THC values of axillar LN+ or LVI+ were higher than the negative ones (P?=?.042 andP?=?.043, respectively). No significant THC difference was found in groups of infiltrating vs. non-infiltrating, HER2+ vs. HER2-, Ki67 high vs. Ki67 low, and different menstrual phases (P?=?.457,P?=?.917,P?=?.417,P?=?.213, respectively).The incidence ages and the lesion-nipple distances of T3 patients were lower than that of T1 and T2 (P?
