Clinical Trial Summary

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.

Recruitment information / eligibility

• Status: Recruiting
• Enrollment: 4
• Est. completion date: July 2014
• Est. primary completion date: March 2014
• Accepts healthy volunteers: Accepts Healthy Volunteers
• Gender: Female
• Age group: 18 Years to 70 Years

Eligibility

Inclusion Criteria:

1. Female patients,locally advanced breast cancer,age =18 years.

2. Histologically confirmed invasive adenocarcinoma of the breast.

3. Primary palpable disease confined to a breast and axilla on physical examination. For patients without clinically suspicious axillary adenopathy, the primary tumor must be larger than 2 cm in diameter by physical exam or imaging studies (clinical T2-T3, N0-N1, M0). For patients with clinically suspicious axillary adenopathy, the primary breast tumor can be any size (clinical T1-3, N1-2, M0). (T1N0M0 lesions are excluded.)

4. Patients without clearly defined palpable breast mass or axillary lymph nodes but radiographically measurable tumor masses are acceptable. Accepted procedures for measuring breast disease are mammography, MRI, and breast ultrasound. This will need to be re-evaluated after 3 cycles and prior to surgery.

5. ECOG 0 or 2

6. No distant metastasis, as documented by complete staging workup =6 weeks prior to initiation of study treatment.

7. No previous treatment for breast cancer.

8. Adequate hematologic function with:

Absolute neutrophil count (ANC) >1500/µL. Platelets =100,000/µL. Hemoglobin =10 g/dL.

9. Adequate hepatic function with:

Serum bilirubin = the institutional upper limit of normal (ULN). Aspartate aminotransferase (AST) =2.5 x institutional ULN. Alanine aminotransferase (ALT) =2.5 x institutional ULN.

10. Adequate renal function with serum creatinine =1.5 x ULN.

11. Planned primary systemic (neoadjuvant) chemotherapy and surgical resection of residual primary tumor (mastectomy or lumpectomy/breast conservation) following completion of neoadjuvant chemotherapy

Exclusion Criteria:

1. inflammatory breast cancer

2. Pregnancy or breast-feeding.A negative serum pregnancy test within 7 days prior to first study treatment (Day 1, Cycle 1) for all women of childbearing potential is required. Patients of childbearing potential must agree to use a birth control method that is approved by their study physician while receiving study treatment and for 3 weeks after their last dose of study treatment. Patients must agree to not breast-feed while receiving study treatment.

3. Concurrent treatment with an ovarian hormonal replacement therapy or with hormonal agents such as raloxifene, tamoxifen or other selective estrogen receptor modulator (SERM). Patients must have discontinued use of such agents prior to beginning study treatment.

4. Uncontrolled intercurrent illness including (but not limited to) ongoing or active infection.

5. Concurrent treatment with any anti-cancer therapy other than those agents used in this study.

6. Mental condition or psychiatric disorder that would prevent patient comprehension of the nature, scope, and possible consequences of the study or that would limit compliance with study requirements.

Study Design

Related Conditions & MeSH terms

• Breast Cancer
• Breast Neoplasms

Intervention

Device:
• Ultrasound
Evaluation of the tumor size by sonography is performed before neoadjuvant chemotherapy and prior to surgery. Measurement of tumor size refers to WHO standards.

Procedure:
• CNB
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.
• BCS, Modified Radical Mastectomy
All patients after neoadjuvant chemotherapy are performed BCS and modified radical mastectomy.

Device:
• Pathologic Large Tissue Selected Table
Pathologic large tissue selected table has obtained Chinese patent.Its license ID is CN101261200. Each piece of breast tissues by cutting with the table has 3mm thickness.
• Leica TP1020

• Pathologic Large Tissue Embedded Table
The table is made of brass .It is applying for a chinese patent. The table can simultaneously embed 8 piece of breast tissues.
• Leica SM2000 R

Device:
• CX22
The residual tumor areas are microscopically outlined on each slice by pathologist.
• Epson V600
Each slice that has been microscopically outlined is scanned by Epson V600. Every image by scanning should be saved as JPG.
• MRI
Evaluation of the tumor size by MRI was performed before neoadjuvant chemotherapy and prior to surgery. Measurement of tumor size refers to WHO standards. The images of patients which were scanned by MRI should be burned onto disc for 3d reconstruction.

Procedure:
• Three-Dimensional Reconstruction
A.Pathological images three-dimensional reconstruction: Pathological images registration is based on skin and shear mark by Photoshop 13.0 software. Residual tumor boundary on Pathological images after registration are outlined and taken three-dimensional reconstruction by 3D-doctor 4.0 software. Observe the shrinkage modes in three-dimensional space. 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. 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

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