Active clinical trials for "Breast Neoplasms"

The investigators at PGIMER have been practicing hypofractionation radiotherapy with a dose of 35Gy/15#/3wks to the chest wall in post mastectomy and 40Gy/16#/3wks in breast conservation in breast cancer patients for the last 4 decades. It is also a routine practice in UK and few centers in Canada. Hypofractionation reduces treatment time to half while maintaining cosmesis and gives control rates equal to conventional fractionation. As breast cancer is a leading cancer in females and radiation therapy is an important part of its local management, hypofractionation help the radiation centers worldwide to meet the growing need for radiation in breast cancer, particularly in developing countries where resources are limited. It also reduces the financial burden on the patient and family. In this study the investigators want to reduce the treatment duration from 3 weeks to 2 weeks. The study will include 1000 patients, 500 in each arm, with breast cancer post mastectomy or after breast conservative surgery to be treated with a radiotherapy dose of 34Gy in 10 fractions over 2 weeks in the study arm and 35Gy in 15 fractions over 3 weeks in the control arm. The primary endpoint of the study will be ipsilateral local tumour control. Secondary endpoints will be early and late adverse effects in normal tissues, quality of life, contralateral primary tumours, regional and distant metastases and survival.

This is a multicenter, prospective, e, real-world cohort survey initiated by researchers to focus on the patterns of breast cancer management and prognosis of breast cancer in China, and to establish the multicenter, prospective breast cancer data platform. A total of 18 sites in Guangdong and Henan have cooperated to build a cooperative network unit. The sites will conduct prospective and standardized records concerning the clinical pathological features, treatment and prognosis of the early breast cancer patients who are treated in their own site each year, registering in the REDCap system.This real-world cohort study aims to provide a representative and reliable survey data of epidemiological characteristics, clinical treatment and prognosis of patients with early breast cancer in China and explore the establishment of a national multi-center breast cancer data platform model.

This is a Phase 1, multiple dose, ascending dose escalation study to define a MTD/RD and regimen of XmAb20717, to describe safety and tolerability, to assess PK and immunogenicity, and to preliminarily assess anti-tumor activity of XmAb20717 in subjects with selected advanced solid tumors.

This phase 1b study will determine the safety and efficacy of combined treatment of Abraxane and phenelzine sulfate (Nardil) for metastatic or locally advanced breast cancer. Participants may be eligible to join this study if they are aged 18 years or above and have been diagnosed with metastatic breast cancer or inoperable locally advanced breast cancer. All participants will receive a combination of intravenous Abraxane and an oral dose of phenelzine sulfate. Abraxane will be administered weekly for the first 3 weeks of a 4-week cycle for 3 consecutive cycles. Phenelzine sulfate will be taken daily for the duration of the 3 cycles. Five patient cohort groups will receive a progressively increasing dose of phenelzine sulfate. Safety and efficacy will be assessed weekly over the 3 cycles of treatment. Although both drugs have been used in clinical care for more than a decade, they have not been intentionally combined together in a cancer therapy setting. This means that the combined effect of these two drugs has not been documented. This is being addressed in this study.

This study is to prospectively investigate the cardiac dose-sparing effect and clinical benefit of deep inspiration breath-hold (DIBH) technique. Patients with left-sided breast cancer treated with breast conserving surgery followed by radiotherapy is enrolled. Radiotherapy is delivered with either free-breathing or deep inspiration breath-hold (DIBH) technique. The cardiac dose parameters and cardiac toxicity are prospective evaluated, and the dose-effect relationship is analyzed.

This is a multi-centre, open label, phase 2, randomised controlled trial of patients with advanced triple negative breast cancer (TNBC) who have received no more than one line of chemotherapy (not including neoadjuvant or adjuvant therapy) who will be randomised to be treated with SABR 20Gy in 1# followed by atezolizumab or SABR 24Gy in 3# followed by atezolizumab.

The goal of this single-group prospective study is to examine the impact of the Healthy Eating and Active Lifestyle (HEAL) Breast Cancer program on participants' perceived stress, biometrics, basic labs, lifestyle behaviors, self-efficacy, mental health, and quality of life. Participants will participate in an 8-week program of 90-minute virtual sessions each week to decrease risk of cancer recurrence. Program participants can choose to participate in the research study which will include data collection (surveys, biometrics, basic labs). The data collection will occur at four timepoints - baseline prior to program start, post-program, 3 month follow-up, and 6 month follow-up.

This is a non-interventional, ambispective, observational cohort study describing the real-world safety data of approximately 550 Hormone receptor / Human epidermal growth factor receptor 2 (HR+/HER2-) advanced/metastatic breast cancer patients who have received ribociclib combined with hormonal therapy in pre-and postmenopausal women or men in Middle Eastern countries.

This study aimed to evaluate the role of serum chemerin as a biomarker of breast cancer. and To investigate the diagnostic value of hsa_circ_0001785 (Circ-ELP3) and hsa_circ_100219 (Circ-FAF1) in serum samples of breast cancer patients to find out whether these circRNAs can utilize as a diagnostic and prognostic biomarker for human breast cancer assessment and make Correlation between serum chemerin levels , serum Circ-FAF1 , serum CircELP3 and classical tumor markers (CEA + CA15-3). andTo elucidate if there is a difference between metastatic and non-metastatic cases as regard serum chemerin levels, serum Circ-FAF1 or Circ-ELP3.

The aim of our study is to examine the cryoimmunologic response and its mechanisms induced by US-guided cryoablation of small breast tumors (<2 cm) not eligible to neoadjuvant therapy. We will recruit 30 women who will undergo cryoablation and their results will be compared with a control group of 30 women, who will follow the same therapeutic pathway without performing cryoablation. All recruited patients will undergo an enrollment check, pre-cryoablation breast MRI and blood test to assess immune response, breast cancer US-guided cryoablation, post-cryoablation breast MRI and the same blood test to evaluate immunologic response. Within 21 days all patients will undergo breast surgery, with immuno-histopathological analysis on surgical specimen. At least 10 days after surgery the patient will undergo clinical breast examination, blood test to assess immune response and patient satisfaction questionnaire. Cryoablation treatment will be performed using a 14G cryoprobe under us-guidance for visualization of the ice ball surrounding the lesion. The ultrasound guide is used to ensure that the action affects the entire tumor and that therapeutic temperatures are reached in every part of the tumor. Pre- and post- cryoablation breast MRI will be performed on a 3T magnet to assess cryoablation rate of success. Artificial intelligence algorithms will also be used for this purpose. Cryoablation treatment efficacy will also be evaluated with ultrasound. The immunological fitness of cancer patients will be studied by flow cytometry, evaluating the presence of cytokines/chemokines relevant during anticancer immune response/tumor progression and for the presence of molecules released by cells during an immunogenic cell death. The goal of our study will be to demonstrate that cryoablation of breast cancer can induce an antitumor immune response. Therefore this approach could become an additional tool in the oncological treatment of breast cancer.
