Active clinical trials for "Breast Neoplasms"

Cardiotoxicity is one of the most significant adverse effects in breast cancer patients treated with anthracyclines (a type of chemotherapy), so we propose to determine whether acute training (i.e., 24h before each chemotherapy session) could reduce the levels of a cardiac biomarker which measures muscle damage (NT-proBNP). Given the fact NT-proBNP attenuation has been observed with one session performed 24h before the first treatment, we propose to verify these findings in each cycle of doxorubicin analyzing how each type of exercise (aerobic, strength or combined aerobic + strength) may impact on anthracycline-induced cardiotoxicity, since this observation may be relevant considering the feasibility and low cost this implementation would represent in clinical practice.

RATIONALE: Radiotherapy (RT) can be indicated to patients submitted to breast-conserving surgery, but, despite the benefits, adjuvant RT can cause contracture generated by tissue fibrosis in patients with immediate prosthetic reconstruction, which could cause prosthesis loss. The biological explanation of this outcome is not fully understood, but recent advances in the analysis of patient-derived blood can contribute to establishing a connection of molecular alterations related to this clinical outcome. There is not a consensus about using hypofractionated RT schemes for patients with BCS and breast reconstruction since no studies had investigated the reasons why some patients lose the prosthesis. PURPOSE: This study will evaluate G3 toxicity rate in breast cancer patients with immediate prosthetic reconstruction, submitted to hypofractionated radiotherapy, analyzing capsular contracture, leakage, infection, and bad positioning in order to demonstrate the noninferiority of Hypo-RT with the conventional RT. Additionally, the molecular profile of blood samples will be investigated in order to find biomarkers related to inflammations processes and response to treatment.

This research study is looking to see how well male breast cancer responds to preoperative treatment with endocrine therapy and which endocrine therapy regimen is the most effective treatment for male breast cancer. The drugs used in this study are: Tamoxifen Anastrozole Degarelix Abemaciclib

A phase 1b study to assess the combination of ARV-471 and everolimus in participants with advanced or metastatic ER+/HER2- breast cancer.

This is a Phase 3, open-label, randomized, clinical trial evaluating the efficacy and safety of gedatolisib plus fulvestrant with or without palbociclib for the treatment of patients with locally advanced or metastatic HR+/HER2- breast cancer following progression on or after CDK4/6 and aromatase inhibitor therapy.

Through a scientific and standardized multicenter, randomized, and controlled study method, the investigators evaluated the clinical efficacy and safety of acupuncture in the treatment of breast cancer-related insomnia, with a view to providing a reliable theoretical basis for the treatment of breast cancer-related insomnia with acupuncture.

In preclinical research, short-term fasting (STF) protects tumor-bearing mice against the toxic effects of chemotherapy, improves the CD8+ effector T-cell intratumor infiltration, while enhancing the chemotherapy efficacy. Short-term use of a "fasting-mimicking diet" (FMD) caused a major increase in the efficacy of cancer treatment in mice comparable to STF. In humans, the investigators recently performed a multicenter randomized phase II trial showing that patients with Human Epidermal growth factor Receptor 2 (HER2) negative breast cancer treated with neoadjuvant chemotherapy and FMD displayed a better radiological response and a better pathological response (90-100% vs <90% tumor cell reduction) than patients treated with chemotherapy without FMD (de Groot, Nat Commun 2020; NCT02126449). Therefore these findings will be validated in a phase 3 trial with the underlying hypothesis that FMD during neoadjuvant chemotherapy for breast cancer improves clinical outcomes, potentially due to improved local immunity.

This is a multicenter, open-label, single-arm, multicohort, two-stage optimal Simon's design, phase II clinical trial that is designed to improve the tolerance of sacituzumab govitecan in patients with unresectable locally advanced or metastatic triple negative breast cancer (TNBC), refractory to at least one, and no more than two, prior standard of care chemotherapy regimens in this setting that is not amenable to resection with curative intent. The goal of this study is to evaluate the safety of sacituzumab govitecan in combination with loperamide and G-CSF in pretreated patients with unresectable locally advanced or metastatic TNBC.

This study aims at assessing the vitamin Dstatus in breast cancer patients who receive letrozole for more than two months and to evaluate effects of vitamin D3 and calcium supplementation on arthalgia caused by letrozole on these patients.

Studies on postoperative adjuvant albumin paclitaxel in domestic breast cancer patients are less reported, especially in large samples, and more studies focus more on the safety and tolerability of albumin paclitaxel use. Head-to-head studies of white violet and docetaxel are not supported by data at this time, but some studies have shown that docetaxel-induced long-term Other adverse effects such as myelosuppression, hepatotoxicity and hypersensitivity reactions can have a serious impact on quality of life. Therefore, this study aims to analyse the efficacy and safety of albumin paclitaxel and docetaxel in the adjuvant treatment of breast cancer in a large randomized controlled trial, and to further analyse the efficacy and safety of albumin paclitaxel in combination with chemotherapy for postoperative breast cancer in different subtypes of breast cancer patients, in order to obtain more realistic data and provide new treatment options for breast cancer patients.
