Pathological complete remission (pCR) after neoadjuvant therapy in HER2-positive early breast cancer patients is closely related to disease-free survival (DFS) and overall survival (OS), which makes pCR an important evaluation indicator of recurrence risk. Trastuzumab combined with pertuzumab is a new standard targeted treatment regimen for HER2-positive early breast cancer. However, there are still quite a few patients who do not reach PCR. For these patients, current guidelines recommend the use of TDM-1 for intensive treatment after surgery, although a significant number of patients still have recurrence or metastasis. Besides, TDM-1 is unavailable in China. Pyrotinib has been approved for HER2-positive breast cancer patients who have previously failed after the treatment of trastuzumab. The investigators intend to conduct this phase II clinical study. Patients with poor response to the standard neoadjuvant treatment regimen of trastuzumab combined with pertuzumab are enrolled. These patients receive pyrotinib to observe that whether pCR has been improved. The investigators aim to explore the effect of pyrotinib in patients with poor response to standard dual-target neoadjuvant therapy, and further explore the improvement of neoadjuvant treatment strategy in HER2 positive early stage breast cancer patients.
This is a randomized, multicenter phase 2 clinical trial to evaluate the efficacy and safety of capecitabine plus pyrotinib versus capecitabine plus trastuzumab plus pertuzumab in patients who have HER2 positive metastatic breast cancer and have not received systemic anticancer therapy for advanced disease.
Circulating tumor cells (CTCs) in peripheral blood originate from breast cancer (primary and metastatic lesions) shedding. Utilization of CTCs as novel and noninvasive tests for diagnosis confirmation, therapy selection, and cancer surveillance is a rapidly growing area of interest. In this project, the investigators will explore a novel detection technology of circulating tumor cells in breast cancer using novel Microfluidic and Raman Spectrum Device. The primary objective is to demonstrate that the CTC assay counts technology can distinguish between healthy subjects and malignant breast cancer subjects. The secondary objective is to demonstrate that the CTCs detection technology can evaluate the efficacy of chemotherapy and neoadjuvant chemotherapy, as well as dynamic treatment monitoring and prognosis evaluation.
To evaluate the efficacy and safety of the SHR6390 in combination with anastrozole, pyrotinib, and trastuzumab in patients with ER-positive, HER2-positive breast cancer in the neoadjuvant setting.
The main objective of the study is to assess the feasibility of a coached physical activity program in the form of an accompanied and adapted water polo program by evaluating the interest aroused in patients for this proposal. treatments (number of participants and sessions performed).
This study evaluates whether SLNB can safely be omitted in breast cancer patients with HER2+ or TN tumors who achieve a radiological complete response on MRI after neoadjuvant systemic therapy
Anthracyclines combined with cyclophosphamide or taxane-containing regimens may cause nail pigmentation which reduces quality of life in breast cancer patients. We conducted this study to investigate nail pigmentation and other skin changes associated with these drugs and aim to evaluate the effect of ice water immersion of hands on nail pigmentation. The first phase is an observational study. Breast cancer patients who received anthracyclines combined with cyclophosphamide or taxane-containing regimens for adjuvant/neoadjuvant chemotherapy are enrolled. The second phase is a prospective phase II study. Early breast cancer patients who plan to receive these drugs for adjuvant/neoadjuvant chemotherapy are treated with ice water immersion of the left hands while their right hands serve as control. The primary end point is the degree of nail pigmentation. The other end points are the incidence of nail pigmentation in both hands, the degree and the incidence of onycholysis, the time from the first chemotherapy to the occurrence of nail pigmentation/onycholysis, the recovery of nail pigmentation/onycholysis, and patient comfort.
Triple negative breast cancer (TNBC), characterized by estrogen receptor, progesterone receptor and HER2 negative, accounts for 10-20% of all breast cancers and usually occurs in young women. It is an aggressive and worst prognosis breast cancer subtype, which urgently requires effective treatment.The pathological complete response (pCR) of neoadjuvant therapy is associated with disease-free survival (DFS) and overall survival (OS) of breast cancer. The correlation between pathological response and long-term survival in patients with early-stage breast cancer is the strongest among patients with triple-negative breast cancer.
This is a retrospective, multicenter, non-interventional study for the evaluation of real-world efficacy and safety of T-DM1 in metastatic/relapsed HER2-positive breast cancer as part of the establishment of hospital medical record collection system to evaluate drug effectiveness by Health Insurance Review & Assessment Service (HIRA). The medical records in approximately 1,000 patients of HER2-positive locally-advanced unresectable or metastatic breast cancer, who have received Kadcyla(Trastuzumab Emtansine, T-DM1) previously, will be collected.
