The Detection of Cell-in-cell Structure (CICs) in Patients With Breast Cancer Undergoing Neoadjuvant Chemotherapy
Study Details
Study Description
Brief Summary
Breast cancer is the most common malignant tumor in women worldwide and neoadjuvant therapy has been the standard care for local advanced breast cancer. Moreover, neoadjuvant therapy undoubtedly provides an ideal model to evaluate the response to therapy. Cell-in-cell structures (CICs) refer to the presence of one or more cells inside host cell, which generally leads to the death of inner cells. Notably, established evidences indicated that CICs were present in breast cancer and tend to impact patient survival. However, whether CICs profile could predict efficacy of therapy remains unclear. In this prospective cohort study, the CICs number and profile will be detected in tumor tissue before and after the neoadjuvant therapy. Then the association between CICs number including dynamic changing and response rate will be explored.

Outcome Measures
Primary Outcome Measures
- pCR(complete pathological response) [Up to 24 weeks.]
no invasive malignant cells identifiable in sections from the site of the tumor(Miller-Payne grades 5) the Miller-Payne grades 4 and 5 patients are grouped as responders.
- Objective response rate (ORR) [Up to 24 weeks.]
Response Evaluation Criteria in Solid Tumors (RECIST):Progressive Disease (PD); Partial Response (PR); Complete Response (CR); Stable Disease (SD) Objective response rate (ORR), defined as the proportion of patients with a complete response (CR) partial response (PR) to treatment.
- Quantification of CIC structure in tumor tissue [Up to 24 weeks.]
CICs number and subtypes in tumor tissue (Core needle biopsy specimens before and after neoadjuvant therapy and surgical specimens based on neoadjuvant therapy.)
Other Outcome Measures
- Disease-free survival (DFS) [Within 5 years after surgery]
It refers to the length of time from the start of medication after enrollment to the death of the patient because of the recurrence, distant metastasis of the disease, invasive contralateral breast cancer, or any other cause.
- Overall survival (OS) [Within 10 years after surgery]
It refers to the length of time from the start of treatment to the death of the patient.
- CEA(carcinoembryonic antigen) [Up to 24 weeks.]
Counts of international units per milliliter (IU/mL) of tumor marker CEA
- CA125(Carbohydrate antigen125) [Up to 24 weeks.]
Counts of international units per milliliter (IU/mL) of tumor marker CA 125
- CA199(Carbohydrate antigen199) [Up to 24 weeks.]
Counts of international units per milliliter (IU/mL) of tumor marker CA 199
