Patients complete half of the whole cycles of neoadjuvant chemotherapy.

Patients complete whole cycles of neoadjuvant chemotherapy.

1. Evaluation of the tumor size by sonography is performed before neoadjuvant chemotherapy and prior to surgery.
2. Measurement of tumor size refers to WHO standards.

Ultrasound

Typically, the pretreatment tumor specimen will be a core needle biopsy. Because 15% to 28% of patients will have no residual tumor after NAT, it is important to have an adequate pretreatment sample in which an unequivocal diagnosis of invasive carcinoma is established and evaluation of hormone receptors and HER2/ neu status is completed before treatment.

All patients after neoadjuvant chemotherapy are performed BCS and modified radical mastectomy.

The residual tumor areas are microscopically outlined on each slice by pathologist.

CX22

1. Each slice that has been microscopically outlined is scanned by Epson V600.
2. Every image by scanning should be saved as JPG.

1. Evaluation of the tumor size by MRI was performed before neoadjuvant chemotherapy and prior to surgery.
2. Measurement of tumor size refers to WHO standards.
3. The images of patients which were scanned by MRI should be burned onto disc for 3d reconstruction.

A.Pathological images three-dimensional reconstruction:

1. Pathological images registration is based on skin and shear mark by Photoshop 13.0 software.
2. Residual tumor boundary on Pathological images after registration are outlined and taken three-dimensional reconstruction by 3D-doctor 4.0 software.
3. Observe the shrinkage modes in three-dimensional space.
4. According to WHO standard,the boundaries of all residual tumor images are displayed in one plane and the longest diameter and its longest perpendicular diameter of boundaries are measured in one-dimensional space.
5. According to RECIST standard,the longest diameter of boundaries of residual tumor images in three-dimensional space.

B.MRI images three-dimensional reconstruction:the procedure is similar to Pathological images three-dimensional reconstruction

Three-Dimensional Reconstruction

1. Evaluation of the tumor size by mammography is performed before neoadjuvant chemotherapy and prior to surgery.
2. Measurement of tumor size and calcification extent refers to WHO standards.
3. Calcification extent is not only measured in mammography image but also under microscope.

The main clinical goal of NAC is to down-stage the primary tumor for BCS,yet BCS after NAC has been associated with significantly higher ipsilateral breast tumor recurrences.The accuracy of breast tumor excision in BCS can dramatically reduce IBTR.The main reseason of IBTR might be the uncertain shrinkage modes of the breast cancer after NAC.This clinical trial is firstly carried out to make clear the shrinkage modes of the primary tumor after 3 cycles and whole cycles of NAC,respectively,with whole-mount serial section(WMSS) and three-dimensional(3D) pathological reconstruction of the residual tumor.The second objective is to investigate the predictive value of 3D MRI reconstruction for the shrinkage modes of the primary tumor after NAC.
