Clinical Application of CTDNA in Operable Breast Cancer Patients

June 11, 2016 updated by: Qiang SUN, Peking Union Medical College Hospital
Our study aims to evaluate the possibility of clinical application of CTDNA detection in samples or peripheral blood of breast cancer patients, so as to act as the new techniques or indicators of early diagnosis, therapy efficiency, or postoperative surveillance of breast cancer.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Probability Sample

Study Population

Operable breast cancer patients who need chemotherapy before or after surgery.

Description

Inclusion Criteria:

  1. Written informed consent must be obtained and documented according to the local regulatory requirements prior to beginning specific protocol procedures.
  2. Age of at least 18 and at most 70 years.
  3. Performance status (Karnofsky-Index) >80%.
  4. Chemotherapy is necessary before or after surgery.
  5. No clinical evidence of local recurrence or distant metastases.
  6. Complete staging work-up within 3 months prior to registration. All patients must have (bilateral) mammography or breast MRI, chest X-ray; other tests may be performed as clinically indicated.
  7. Life expectancy of at least 2 years, disregarding the diagnosis of cancer.
  8. Adequate organ function including normal red and white blood count, platelets, serum creatinine, bilirubin, and transaminases within normal range of the institution.
  9. Patients must be available for and compliant to treatment and follow-up.
  10. Patients registered on this trial must be treated and followed up at the participating center.

Exclusion Criteria:

  1. Known hypersensitivity reaction to the investigational compounds or incorporated substances.
  2. Local recurrence and/or metastasis of breast cancer.
  3. No need of chemotherapy.

  4. Pregnant or lactating patients. Patients of childbearing potential must have a negative pregnancy test (urine or serum) within 14 days prior to registration.

    Prior or concomitant secondary malignancy (except non-melanomatous skin cancer or carcinoma in situ of the uterine cervix)

  5. Any other serious medical pathology, such as congestive heart failure; unstable angina; history of myocardial infarction during the previous year; uncontrolled high risk arrhythmias
  6. Other serious illness or medical condition that may interfere with the understanding and giving of informed consent and the conduct of the study.
  7. Concurrent treatment with other experimental drugs or any other anti-cancer therapy.
  8. Males.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
