This clinical trial evaluates the added role of contrast-enhanced mammography (CEM), as well as imaging and blood biomarkers, for predicting the presence or absence of high-grade ductal carcinoma in situ (DCIS) or invasive cancer on pathology. Screening mammography is the mainstay of population-wide early breast cancer detection, and mammography-detected cancers are usually of an earlier stage, giving women the best chance of survival. However, the main drawbacks of this type of screening are false positive results and potential over-diagnosis of breast cancer. Suspicious microcalcifications detected with mammography pose a particular diagnostic problem, as they may be associated with invasive and high-grade in-situ cancers like DCIS, but are more often benign or require further workup to verify diagnosis. As such, microcalcifications detected by mammography pose a risk of both over-diagnosis and underestimation of disease severity. This study evaluates the impact of using CEM, compared to standard full field digital mammography (FFDM) for the management of suspicious microcalcifications and prediction of breast cancer in women with this finding.
Hypofractionated radiotherapy could provide more convenient treatment and had similar toxicities.However,reports of hypofractionated radiotherapy with two-stage expander/implant reconstruction are rare,Some studies have shown that hypofractionated radiotherapy had similar toxicities to conventional fractionated radiotherapy in patients with breast reconstruction. So,investigators conducted a phase II study to observe the reconstruction failure in hypofractionated radiotherapy with two-stage expander/implant reconstruction.
This project is a case-control study which seeks to identify modifiable risk factors for breast and colorectal cancer in Nigeria. Both cases and controls will be required to complete a risk factor questionnaire which contains information about their diet, physical activity, past medical history and life style factors. They will also be required to provide information on their body composition through the use of a bioimpedance machine which measures the body mass index, fat and total body water percentage. Based on the existing ARGO platform where a current colorectal cancer study is going on, approximately 400 patients with a prior diagnosis or a new diagnosis will be recruited into this study. Comparatively, we will select our 400 controls from two groups of participants who are free of cancer and gastrointestinal diseases.
In this study, the safety, tolerability and preliminary effectiveness of GNC-035 in participants with locally advanced or metastatic solid tumors will be investigated to assess the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) or maximum administered dose (MAD) for MTD is not reached of GNC-035.
The purpose of this study is to find out how much oxygen is used during a cardiopulmonary exercise test (CPET) in women who have mild cardiotoxicity after standard treatment for HER2-positive breast cancer, and to see whether the results of this test can be used to predict how well participants' heart and lungs will work if they continue to receive this kind of treatment.
This clinical trial investigates contrast-enhanced mammography (CEM) in detecting breast cancer. CEM is similar to standard mammography, but it includes an injection of an iodine-based contrast, which makes tissue and blood vessels more visible in scans. Diagnostic procedures, such as CEM, may increase the chance of finding breast cancers and decrease the risk of having unnecessary biopsies.
The treatment of patients with HER2 positive early breast cancer has continuously improved over the last decades. Up to now both, trastuzumab and pertuzumab are approved in combination with chemotherapy (CTX) not only for the adjuvant but also for the neoadjuvant treatment of early breast cancer patients. A high pCR rate in the neoadjuvant setting was shown in several trials and observational studies with CTX+ trastuzumab and with CTX+ pertuzumab. The efficacy is dependent on a variety of mechanisms including the blocking of the important PI3K/Akt and MAPK pathways, and ADCC (antibody dependent cellular toxicity). Recently the biosimilar Ontruzant® (SB3) has been introduced into the treatment of HER2 positive breast cancer as a biosimilar. Efficacy and toxicity have been shown to be equivalent to the first approved antibody, however, data from the real-world setting have not been published like it has for the originally approved antibody. Therefore, the aim of this study is to establish safety and efficacy for Ontruzant® in the real world setting. Patients can be included if they are treated with Ontruzant® in the neoadjuvant setting. Additionally, the study will be accompanied by a comprehensive immune monitoring program and biomarker program to explore immune oncology potential for the neoadjuvant treatment.
This study's aim is to evaluate the feasibility of introducing a women's malignancy survivorship clinic incorporating symptom management through ePRO collection (complex intervention) into routine follow up care in patients with early-stage Hormone Receptor(HR)-positive breast and gynaecologic cancer post primary curative therapy.
After progression of disease after one chemotherapy, metastatic breast cancer patients will be randomized 1:1 to one of the following treatment arms: Arm A. Eribulin Arm B. Paclitaxel Blood draws for immune analysis will be performed before start of therapy, on day 1 of cycle 2 and on day 21 of cycle 4 (end of therapy) for the primary study aim. Patients will be treated under study conditions for a maximum of 4 therapy cycles.
The breast cancer patients who received radiotherapy after mastectomy and breast reconstruction will be enrolled. The skin microbiome before radiotherapy and its changes after radiotherapy will be analyzed systematically to find out whether the skin microbiome is associated with the severity of radiation dermatitis.
