Filter by:The goal of this observational study is to learn about the value of 18F-FAPI-RGD PET/CT imaging in Breast Tumors. Participants will undergo clinical evaluation and 18F-FAPI-RGD PET/CT examination.
The purpose of this study is to establish a prospective, single-center platform research based on clinical subtypes to explore precision neoadjuvant therapy in patients with operable breast cancer who met the indications for neoadjuvant chemotherapy and by the update of basic translational research in the center, especially the refinement of typing, the discovery of new targets and the development of novel targeted drugs, verified the effectiveness of new targeted drugs in neoadjuvant therapy.
The purpose of this study is to further advance the ability to practice personalized medicine by learning which new drug agents are most effective with which types of breast cancer tumors and by learning more about which early indicators of response (tumor analysis prior to surgery via magnetic resonance imaging (MRI) images along with tissue and blood samples) are predictors of treatment success.
This protocol aims to create a tissue bank of breast tumors obtained at the time of diagnosis for the identification of biomarkers for diagnosis, prognostication, and prediction of treatment response in breast cancer. While tissue banks now exist in major hospitals in Singapore to collect tumor specimens at the time of surgery, specimens collected at surgery from patients who had undergone pre-operative treatment represent a post-treatment sample and not a baseline, untreated sample. Such samples are intrinsically different from untreated samples, and have to be analyzed separately from untreated samples. However, they remain valuable samples, particularly if a pre-treatment sample has been obtained, providing paired pre- and post-treatment samples, which could provide valuable information on treatment-related tumor biomarker changes. A tissue bank comprising of samples collected during the diagnostic core biopsy thus represents a valuable supplement to existing tissue banks. Approximately 10-20% of patients diagnosed with non-metastatic breast cancer will require neoadjuvant chemotherapy. In addition, future clinical trials may include 'window-of-opportunity' studies during which biological therapy is administered for a short period (2-3 weeks) while an operable breast cancer patient is awaiting definitive surgery. The majority of early-stage breast cancer patients would be eligible for such trials, allowing the rapid recruitment of breast cancer patients. When coupled with analysis of surrogate markers of response (eg apoptosis, anti-angiogenic effects, etc), these unique clinical trials could provide valuable insights into the biological effects of new therapeutic agents in evaluation.
