Objective To measure volume of breast cancer , calculate tumor volume doubling time (TVDT), and analyze the correlated factors affecting TVDT using three-dimensional ultrasound (3D-US). Methods We applied 3D-US to measure the volume of breast cancer of BI-RADS-US 4A classified by conventional ultrasound. The breast cancer case scanned by 3D-US at least twice (the interval is 3 months at least) without any medical intervention were included in the study. We calculated TVDT according to the formula, and analyzed the affecting factors of TVDT using multiple linear regression. Results Sixty-nine cases were enrolled in the study. The TVDT of breast cancer were from 66 to 521 days , in an average of 185 ± 126 days and the median time of 164 days. We found that: ① there were no statistics significances in TVDT between different breast cancer pattern , smoothing border lines , speculated sign , hyperechoic halo , microcalcification and different rear echo (P > 0.05). ② TVDT of different age groups, lymph node metastasis, pathological grade and NPI score were significantly different (P < 0.05), while menstrual cycle, family history of breast cancer and molecular typing showed no difference (P > 0.05). ③ TVDT of patients with different expression of ER, PR and Ki-67, molecular typing showed statistically difference (P < 0.05), but there was no significant difference between different level of HER2 (P >0.05). ④ multi-factor analysis showed that the NPI score, lymph node metastasis, Ki-67 and molecular typing of breast cancer were relative factors in TVDT (P < 0.05). Conclusions The NPI score , lymph node metastasis , Ki-67 and molecular typing significantly correlate with TVDT of breast cancer. Triple-negative breast cancer in molecular typing has the fastest growth rate.

Objective To investigate diagnostic efficiency of vascular parameters in the diagnosis of BI-RADS Ⅳ breast masses using three-dimensional power Doppler ultrasound (3D-PDUS).Methods After adjusting the ultrasonic instrument under property conditions,3D-PDUS were applied to scan BI-RADS Ⅳ breast masses before surgery with QLab software,the following parameters of breast masses were obtained:total tumor volume,vascularization index (VI),flow index (FI),and vascularization flow index (VFI).According to the pathological results,the diagnostic value of vascular parameters from 3D-PDUS were assessed with receiver operating characteristic (ROC) curve,and the diagnostic efficiency were analyzed by best cut-off limits of various vascular parameters.Results The volume and vascular parameters of benign group were remarkably lower than those of malignant group (all P ＜0.001).The area under the ROC curve (AUC) of VI (0.873) ＞VFI (0.866) ＞FI (0.778).AUC of FI was significantly smaller than that of VI (P =0.016) and of VFI (P =0.039),while no statistical difference between that of VI and of VFI (P =0.294).The diagnostic accuracies of VI (cut-point:1.2,sensitivity:84.1％,specificity:83.3 ％,accuracy:83.8 ％) and of VFI (cut-point:0.5,sensitivity:82.5 ％,specificity:85.2％,accuracy:82.9％) were higher than that of FI (cut-point:35.3,sensitivity:74.6％,specificity:70.4 ％,accuracy:72.6 ％).AUC of VI (P =0.001) and of VFI (P =0.033) in small-volume group (＜2cm3) were both larger than those of large-volume group (≥2 cm3),no significant difference in AUC of FI between these two groups (P =0.09).Conclusions Vascular parameters obtained using 3D-PDUS have affirmative value in the diagnosis of BI-RADS Ⅳ breast masses,especially in masses less than 2 cm3 in volume.
