Active clinical trials for "Breast Neoplasms"

In Ireland, over 3,000 patients are diagnosed with breast cancer annually, and 1 in 9 Irish women will be diagnosed with breast cancer in their lifetime. There is evidence that female breast cancer survivors are more likely to die of cardiovascular disease than their age-matched counterparts. This research is focused on evaluating pathways for identifying, managing, and overcoming side effects of cancer therapies that can negatively impact quality-of-life and overall outcomes for women during and after cancer treatment. The Cardio-oncology research team at GUH plan to capitalize on their expertise in both cancer care and cardiology to develop a care pathway for cancer patients who are at increased risk of developing heart disease.

This study evaluates whether there are pre-treatment factors such as patient characteristics, specific breast cancer type, specific treatments, toxicities, or adverse events during treatment that may impact the quality of life and function, 3 years or more after the treatment, in cancer-free subjects. There will be 2 groups. Cohort A: Women who participated in previous studies namely NCT02167932, NCT02328313, and NCT03761706, will be re-contacted and consent for this study activities. Cohort B: Women with breast cancer, who did not receive chemotherapy, will be consented to be included in the study, and their electronic medical data will be used. Furthermore, the long-term effects of treatment and a biomarker of aging cyclin-dependent kinase inhibitor 2A (CDKN2A,p16INK4a) and relation will be assessed.

The purpose of this study is to learn if certain drug combinations are effective treatments for patients with advanced ER+/HER2- who have previously been treated with palbociclib, ribociclib, or abemaciclib.

This study is a post-marketing, observational, multicenter, prospective study. It will investigate the the safety and effectiveness of T-DM1 in the Chinese population in real-world clinical practice.

Patients who experienced neutropenia after receiving pegfilgrastim on day 1 of the first round are randomly assigned to either the control or experimental arm. Patients in the control arm continue pegfilgrastim injection on day 1 while patients in the experimental arm will receive pegfilgrastim injection on day 3 to see if changing the pegfilgrastim administration date from day 1 to day 3 starting from the second round of chemotherapy could reduce the incidence of neutropenia

The goal of this clinical trial is to evaluate the efficacy of investigator's choice of chemotherapy, either alone or in combination with everolimus, in treating patients with locally recurrent inoperable or metastatic triple-negative breast cancer, luminal androgen receptor (LAR) subtype with PI3K/AKT/mTOR (PAM) pathway mutation, as the first-line treatment.

This is a prospective, randomized, open-label phase III clinical study on the efficacy and safety of fluzoparib combined with adjuvant endocrine therapy versus adjuvant endocrine therapy for HR+/HER2- SNF3-subtype early breast cancer.

We plan to carry out a phase II, open-label, single-arm clinical study of short-course trastuzumab, pertuzumab combined with taxanes in the adjuvant treatment of early HER2-positive breast cancer, to explore whether 4 courses of dual HER2 blockade combined with taxanes can lead to a similar prognosis with current standard treatment, which is one-year trastuzumab monotherapy combined with chemotherapy, while reducing the adverse reactions of treatment.

The incidence of breast cancer in Chinese women has increased year by year, and luminal A breast cancer commonly occurs in early-stage and postmenopausal women. This type of breast cancer is not sensitive to chemotherapy, although it has a low mortality rate and distant metastasis rate. Studies have shown that luminal A breast cancer is sensitive to endocrine therapy. Patients with breast cancer who undergo excision should be followed up and their prognosis should be monitored regularly. At present, imaging detection is mainly used in the conventional follow-up of breast cancer, but the cost of many imaging examinations is high, so a cost-effective examination is urgently needed. Recent studies have found that circulating tumor cells can be used as a new type of tumor molecular marker, which can be used to diagnose tumors, judge the prognosis and monitor the efficacy by detecting the number and characteristic protein expression of circulating tumor cells. Because circulating tumor cells may develop abnormalities 4-6 months earlier than conventional imaging examination, as long as circulating tumor cells of patients are abnormal, timely PET-CT examination will neither miss diagnosis nor delay the condition. Simultaneously, the cost of hospitalization can be obviously reduced. This non-inferiority randomized controlled clinical trial is designed to compare the differences in postoperative conditions between circulating tumor cell detection and conventional imaging examination in patients with luminal A breast cancer without lymph node metastasis.

Cardiomyopathy is a condition that affects the heart muscle, whereby it becomes enlarged, thick or rigid. When the heart muscle becomes involved, it affects the pumping action of the heart. This condition can affect as many as 10% of all patients after undergoing anthracycline cancer drug therapy and unfortunately carries the worst prognosis of all cardiomyopathies. To date, there is no effective intervention that will prevent a patient from developing this condition. The research conducted will look to see if an energy imbalance in the heart predates the onset of detrimental changes to the pumping function of the heart, if this is detected then we can act earlier to prevent the pumping function deteriorating.
