Trial summary

Chemotherapy combined with trastuzumab and patuzumab is the standard neoadjuvant therapy for HER2 positive breast cancer patients. The survival rate of patients with pathological complete response (PCR) after neoadjuvant therapy was significantly better than that of patients with tumor residue, that is, non-PCR.

About this study

Official title: A Cohort Study of Different Choice of Adjuvant Therapy in Non-PCR Patients With HER2 Positive Early Breast Cancer After Neoadjuvant Therapy

Chemotherapy combined with trastuzumab and patuzumab is the standard neoadjuvant therapy for HER2 positive breast cancer patients. The survival rate of patients with pathological complete response (PCR) after neoadjuvant therapy was significantly better than that of patients with tumor residue, that is, non-PCR. Therefore, studies have confirmed that adjuvant therapy for patients with non-PCR after neoadjuvant chemotherapy can further improve the prognosis and survival of this population. However, the results of previous studies are based on trastuzumab target therapy in neoadjuvant therapy. Therefore, there are different recommendations for the current guidelines of adjuvant therapy after trastuzumab combined pertuzumab target neoadjuvant therapy. Patients with HER2 positive breast cancer who received trastuzumab and patuzumab based neoadjuvant therapy had invasive residual cancer in postoperative pathology. The effect of postoperative adjuvant therapy with trastuzumab and patuzumab or replacement of T-DM1 on survival.

Read the detailed description

Investigators retrospectively recruited patients with HER2 positive breast cancer who received trastuzumab and patuzumab based neoadjuvant therapy had invasive residual cancer in postoperative pathology from January 1, 2019 to November 31, 2024, and prospectively recruit patients of the same type from December 1, 2024 to December 31, 2028.

Inclusion Criteria:

  1. Patients with HER2 positive breast cancer were diagnosed by biopsy in Peking University People's hospital;
  2. The clinical stages before treatment were T1-T4, N0-N3, M0;
  3. Received treatment and operation in our hospital, and had hospitalization records;
  4. Receive at least 4 cycles of trastuzumab and pertuzumab target therapy combined chemotherapy as neoadjuvant therapy
  5. Postoperative pathology confirmed the presence of residual invasive breast cancer in the breast and/or metastatic tumor lesions in axillary lymph nodes;
  6. Has signed and agreed to participate in the PKUPH breast disease cohort study.

Exclusion Criteria:

  1. Lack of clinical and pathological data (such as imaging data and pathological data);
  2. Patients with metastatic breast cancer or bilateral breast cancer;
  3. Failure to perform radical surgery;
  4. Receiving other regimens besides the established neoadjuvant regimens.

The therapy choice Arm 1: The postoperative adjuvant regimen is a combination of trastuzumab and pertuzumab, with a planned treatment duration of 1 year; Arm 2: Postoperative adjuvant therapy was T-DM1, with a planned treatment duration of 1 year.

Primary end point 3-years invasive disease free survival

    Measured: 3 years

  2. distant disease free survival

    Time from study enrollment to distant recurrence and metastasis

    Measured: 3 years

  3. breast cancer specific survival

    Time from study enrollment to death due to breast cancer

    Measured: 3 years

  4. overall survival

    Time from study enrollment to death from any cause

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

An observational study of HER2-positive Breast Cancer, run by Shu Wang at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 20 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact yuan peng, doctor (86+13671287670, 13671287670@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

invasive disease free survival (time frame: 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Nov 2024.
