Compare the Outcomes of XT and XEC Adjuvant Chemotherapy in HER2-negative Luminal B Breast Cancer Patients

January 28, 2013 updated by: Liao Ning, Guangdong Academy of Medical Sciences

A Phase III，Randomized ，Multi-center Clinical Trail to Compare the Outcomes of XT and XEC Adjuvant Chemotherapy Protocol in HER-negative Luminal B Breast Cancer Patients Who Reached Pathologic Response After XT Neoadjuvant Chemotherapy

Human epidermalgrowth factor receptor-2(HER2) negative Luminal B subtype breast cancer patients are included. After 4 cycles of Capecitabine combined with Docetaxel(XT) protocol neoadjuvant chemotherapy ,those who reach partial response(PR) but not pathological complete response(pCR) are randomly divided into the group treated with XT protocol and the group with Capecitabine combined with Epirubicin and Cyclophosphamide(XEC) protocol ,then compare the disease free survival(DFS) and overall survival(OS) of two subgroup.

Detailed Description

Individualized treatment of breast cancer has become one of the main directions in the clinical and research areas of breast cancer,and the individualized treatment of the estrogen receptor(ER) positive patients which covered 65% of total cases is of vital importance. Historical research showed that among the ER-positive and HER2-negative breast cancer,Luminal B breast cancer with Ki67>14% is more likely to be benefited from chemotherapy,compared with the Luminal A breast cancer with Ki67<14%. And the results of our previous research showed that, the neoadjuvant XT protocol has more than 17% pCR rate in Luminal B subtype breast cancer.However,to those who didn't reach pCR,we've got no evidence whether switching to Anthracycline-based post operative protocol can benefit them.So that,we sketch out a randomized controlled multicentric phase III clinical trail.HER2 negative Luminal B subtype breast cancer patients are included. After 4 cycles of XT protocol neoadjuvant chemotherapy ,those who reach PR but not pCR are randomly divided into the group treated with XT protocol and the group with XEC protocol ,then compare the DFS and OS of two subgroup.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Disease free survival after adjuvant chemotherapy within five years
Time Frame: Within 5 years after adjuvant chemotherapy
Within 5 years after adjuvant chemotherapy,we should evaluate disease free survival and overall survival rates as the most important outcome measure.
Within 5 years after adjuvant chemotherapy
Overall survival after adjuvant chemotherapy within five years
Time Frame: Within five years after adjuvant chemotherapy
Within 5 years after adjuvant chemotherapy,we should evaluate overall survival (OR)rates as the most important outcome measure.
Within five years after adjuvant chemotherapy

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Imaging evaluation after neoadjuvant chemotherapy
Time Frame: within the 21 days after neoadjuvant chemotherapy
After neoadjuvant chemotherapy,we should evaluate the status of patients as progress disease and then use the imaging evaluations as the proofs to plan their next therapeutic schedule or different grouping methods.
within the 21 days after neoadjuvant chemotherapy

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Baseline evaluation
Time Frame: before the neoadjuvant chemotherapy
Baseline evaluation includes the issues of ECOG PS scores, primary tumor Imaging evaluation, evaluation and reserve of bone marrow and organ function evaluation.
