Abstract:
Objective To explore the ultrasound-guided diffuse optical tomography (DOT) distribution difference and clinical characteristics of T 1-T3 breast carcinoma. Methods Four hundred and forty-seven breast cancer patients with 455 breast lesions were enrolled.The lesion maximal diameter and total hemoglobin concentration(THC) were obtained by ultrasound-guided DOT before breast surgery biopsy.The patients age,body mass index(BMI),and the distances from lesion to skin and nipple were measured,lymph node status were also assessed.According to the 7th Edition of the AJCC Cancer Staging, all tumors were divided into T1( ≤ 2 cm),T2(2 cm < lesion ≤ 5 cm),and T3( > 5 cm) three groups according to maximum diameter on ultrasound.Results Out of 455 breast cancer lesions,148 lesions were stage T1,251 lesions were stage T2,56 lesions were T3.The age,lesion size,lesion THC and the distances between lesions and nipples of breast cancer patients were found that there were significant differences among T1,T2 and T3(all P = 0.000). With T stages increasing,the age of breast cancers patients decreased,the distance between lesions and nipples decreased,the THC increased.THC of breast cancer T 2 [(221.0 ± 56.0)μmol/L] and T3[(233.1 ± 54.0)μmol/L] were significant higher than that of T1 [(181.6 ± 70.4)μmol/L](all P = 0.000).There were all no significant difference for BMI and the distancefrom lesion to skin among different stages T( P > 0.05).With T stages increasing,the ratio of lymph node metastasis increased(T1 26.4%,T2 49.8%,T3 55.4%; P =0.000).Conclusions With breast cancer T stages increasing,T HC increases,the age of the patients decreases,lymph node metastasis rate increases.
