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.

Detailed Description

Breast cancer (BC) is one of the most common malignant tumors in global population, with the highest morbidity and mortality rates among female.(1) Neoadjuvant chemotherapy (NAC) has become an important supplement of comprehensive and precise treatment of BC. Neoadjuvant chemotherapy (NAC) is increasingly used to induce tumor shrinkage, thereby allowing smaller surgical resection, eliminating clinically silent micro metastases, and providing prognostic information based on the extent of pathologic response(.2-4) Pathological complete response (pCR) is increasingly seen after neoadjuvant chemotherapy (NACT) for invasive breast cancer. Confident identification of pCR may lead to less radical breast surgery and to sentinel node biopsy rather than axillary clearance in women with pre-treatment positive nodes.(5)Response to NACT is routinely assessed using magnetic resonance imaging (MRI), greyscale ultrasound (US), and mammography.(6) In some studies, MRI has been shown to be superior to US.(7-8) however, MRI has the disadvantages of being time-consuming, expensive, requiring intravenous contrast agent . Ultrasonic elastography (UE) has been widely used to qualitatively and quantitatively evaluate differences in lesion stiffness or elasticity. Currently, the two most frequently used UE techniques for examination of breast diseases are strain elastography (SE) and shear-wave elastography (SWE). In practice, UE is a complementary technique for differentiating benign from malignant breast masses (9,10). Breast cancers with more aggressive pathological properties tend to have higher stiffness values .Strain elastography (SE) may be predictive of response in the early stage of treatment with high sensitivity (SEN) and specificity (SPE).(11,12) Pretreatment tumor stiffness measured by shear wave elastography (SWE) has a significant relationship with the subsequent reduction in tumor cellularity.(13) In case of NACT, early evaluation of relative changes in tumor stiffness could effectively predict the response and might indicate better therapeutic strategies.(14)

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.

Study Major Dates

Study Start (Anticipated)

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.
