Active clinical trials for "Breast Neoplasms"

The purpose of the study is to survey how many women have breast implants in the mammography screening population and the effect of implants on the number and type of examinations and on costs.

This project will engage anti-HER2 directed Trastuzumab biosimilar with a novel quality of ePRO and enable comparison of reliable reference real world patient data, thereby creating a basis for analytic research in order to promote the quality and efficiency of treatment

To observe the efficiency for patient with stage II-III HR+/HER2+ early breast cancer with standard neoadjuvant therapy, a retrospective, multicenter study in real world settings.

This is a multi-center, retrospective-prospective, observational, active-control, non-inferiority, real world study using hospital medical record data, with objectives to evaluate E2 suppressive effect of Zoladex® 10.8 mg is non-inferior to Zoladex® 3.6 mg. Eligible breast cancer patients who received Zoladex® from January 1st, 2015 till December 31st, 2021(including December 31st, 2021) will be identified and included for retrospective data collection and analyses in this study. And prospective data will be monthly collected of eligible patients receiving Zoladex® after January 1st, 2022 (including January 1st, 2022) until approximately 1000 patients being included in this study for analysis. (If site has specific identification of retrospective data and prospective data, it will be subject to the requirement of site). The first date of the presence of Zoladex® treatment or prescription record for breast cancer during the study period will be considered the index date for patients. According to the Zoladex® treatment at the index date, patients will be categorized into two cohorts: Zoladex® 10.8 mg or Zoladex® 3.6 mg. About 10-15 hospitals will be included in this study. To be considered, the hospitals need to have relatively large number of eligible patients, geographic representativeness and willingness to participate in this study. Approximately 1000 eligible patients from selected hospitals during the study period will be included and matched with propensity scores. It is expected that at least 150 matched patients in each of the two cohorts will eventually be included in the primary endpoint analysis. The final subject number will be based on the actual situation of the study.

To explore the cognitive impairment caused by chemotherapy and endocrine therapy in premenopausal breast cancer patients and to find biomarkers with early predictive effect on this cognitive impairment by using multimodal integrated PET/MRI technology combined with psychobehavioral technology.

In women with newly diagnosed breast cancer, synchronous contralateral breast cancer is reported in 1% to 3%. During the initial diagnosis of breast cancer, it is important to detect the contralateral cancer to avoid second round of cancer therapy. Because breast MRI is a highly sensitive modality, it is used for screening of occult contralateral disease in women newly diagnosed with breast cancer and detects contralateral cancers not seen on clinical or conventional imaging (mammography and ultrasonography) in 4.1% of women. However, the use of breast MRI for screening contralateral breast cancer, is limited not only by high costs and long examination time but also by high false-positive findings resulting in more benign biopsies and extensive surgeries. In addition, the use of intravenous gadolinium-based contrast agent is contraindicated in pregnancy and in women with renal impairment or contrast material allergy contrast. Thus, there is a need to develop a more safe and cost-effective supplemental imaging modality for screening breast cancer. Diffusion-weighted (DW) MRI is a fast, functional modality that measures the movement of water molecules to create tissue contrast without the need for contrast injection. Breast malignancies exhibit hindered diffusion and appear hyperintense on DW MRI with low apparent diffusion coefficient (ADC) compared to normal surrounding tissue. A number of studies have shown that the use of DW MRI can significantly reduce the false positives and unnecessary benign biopsy of breast MRI. Several studies have explored how to use DW MRI as a stand-alone tool for breast cancer screening, and recent results have shown that DW MRI is more useful than conventional imaging in detecting small breast cancer. However, most of these studies were retrospective with inconsistent results. Thus, a prospective multicenter study with standardized acquisition and interpretation protocols in a large population is needed to determine the efficacy of DW MRI for breast cancer screening. The purpose of our study is to determine whether DWI improves the performance of preoperative DCE MRI in detecting clinically occult contralateral breast cancers.

In Italy, 50% of new breast cancer (BC) diagnosis occur in female of working age. Although return to work (RTW) is strongly desired by BC patients, cancer survivors are more likely to be unemployed than healthy individuals. Moreover, work difficulties may hindrance this process. Since 2018, the investigators have planned a local social-healthcare pathway which provides a multidisciplinary vocational rehabilitation intervention with the aim to help cancer survivors in their RTW process. To date, the feasibility of the multidisciplinary vocational rehabilitation interventions has not been verified for BC patients.

The purpose of this study is to compare the efficacy, safety, pharmacokinetic, and immunogenicity of Pertuzumab (Test, Cadila Healthcare Ltd.,) plus Trastuzumab and Docetaxel versus Pertuzumab (Reference, Genentech Inc.,) plus Trastuzumab and Docetaxel treatment in previously untreated patients with HER2 positive MBC.

This is a prospective, multicenter, open-label, non-comparative, non-interventional, observational study to assess te safety and effectiveness of Piqray in the real-world setting

High Intensity Focused Ultrasound (HIFU) is a new method of treating solid tumours by thermally ablating them. It has been used in a number of different types of cancers but there is little information on its use in invasive breast cancer (IBC). The investigators aim to assess the efficacy and safety of HIFU in the treatment of IBC. In this study, fifteen otherwise healthy women diagnosed with small, early stage IBC will be treated with HIFU prior to conventional surgical treatment. The effects of HIFU on the resected tumour will be analysed pathologically and correlated with radiological findings. Immune response and participant experience will also be evaluated
