About this study

The purpose of this stage of study is to establish discriminant among healthy tissue, benign and malignant thyroid and breast tumors by fourier transform infrared spectrometry variables.

Read the detailed description

Recently,the methods to the diagnosis of tumors include palpation,X-ray,ultrasound,CT and MRI.The doctors could not get conclusion without a existing mass.The FNB is very popular nowadays in western countries,but it has been reported that about one-third malignant cases have been neglected by FNB,for the tissue isn't enough through the needle.There also have been reports about the increased auxilliary lymphnode metastases for breast cancer because of FNB.Although the Mammotome has been used widely,it is still traumatic.

Process of malignant transformation of tissues and cells, first proteins, lipids, carbohydrates and nucleic acids constitute the main substance of tissue and cell structure, conformation, and the number of occurrence of significant changes in subsequent histological changes. Fourier transform infrared spectroscopy is the major molecular bond coupling between the atoms vibrational spectra and molecular rotational spectra.

In this study, consists of three phases:

Stage one:

Continuous enrollment requires inpatient surgery 300 cases of thyroid cancer patients and breast cancer patients, 200 cases of preoperative determination of tumor on the surface infrared spectroscopy, infrared spectroscopy of the anterior tumor tissue and lymph node surgery, measured in vivo; at the same time into the group of 50 patients healthy people, the determination of surface infrared spectroscopy of the thyroid and breast area. Paraffin pathological findings as the gold standard, the thyroid and breast cancer patients were divided into the benign group and malignant group, relatively healthy and good, the distribution of differences of the surface infrared spectrum of malignant group, while relatively good in the malignant group IR spectra of the distribution of differences.

Phase II:

Were enrolled, infrared spectroscopy and pathological specimens were collected at different stages. Paraffin pathological findings as the gold standard, were established two tumor surface, the infrared spectra of the fresh in vitro and in vivo for tumor benign or malignant diagnosis discrimination system.

Phase III:

Into the infrared spectra collected data on behalf of the above-mentioned discrimination system to verify its sensitivity, specificity and accuracy; both paraffin pathological findings as the gold standard to compare the infrared spectral discrimination systems and intraoperative frozen section pathology for the diagnosis of benign and malignant tumors correctly rate differences, to explore the clinical value of infrared spectroscopy discrimination system.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. pathologic findings

    1. In operation patients, discriminant between benign and malignant thyroid and breast tumors are established by fourier transform infrared spectrometry variables, and pathologic diagnoses are gold standard.
    2. Between Patients and healthy volunteers, discriminant are established among thyroid and breast tumors and healthy tissues.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Thyroid Tumor and Breast Tumor, run by XU Zhi 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?

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: status not confirmed, as of the sponsor's last update on 20 Aug 2012. 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?

Results are not available in the source record.

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

Contact Zhi XU, PHD MD (86-10-82267331, xuzhi123456@sohu.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

pathologic findings (time frame: 12 months). 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 Aug 2012.
