Filter by:Patients with locally advanced (stage III) breast cancer (LABC) are characterized by a significantly worse prognosis compared to patients with primarily operable breast cancer. While neoadjuvant chemotherapy has been the first choice in this situation for several decades, recent evidence suggests that some patients may experience an extraordinary effect from neoadjuvant endocrine treatments involving aromatase inhibitors as monotherapy or in modern drug combinations.Selected LABC patients admitted for treatment will be offered combination therapy including letrozole and ribociclib. The overall goal of the project is to improve understanding of tumor responses and resistance in patients suffering from ER-positive/HER-2 negative locally advanced breast cancer, focusing on the role of the immune system including the gut microbiome.
The aim of this study is to compare the efficacy of the Sentimag localization system and its tracer Magtrace, superparamagnetic iron oxide nanoparticles, as a tracer in sentinel node biopsy in breast cancer with Tc99 in a single-center prospective study. The other part of the study will be the implantation of the smallest non-radioactive seed, Magseed, in the non-palpable breast cancer lesions. Another part of the study will be the implantation of Magseed in the positive axillary lymph nodes in patients diagnosed with clinically positive lymph nodes that will receive neoadjuvant systemic therapy.
Background: Online interventions can be a fast, cost-efficient, and convenient medium for providing breast cancer patients (BCP) with access to evidence-based interventions that address their emotional needs. As true as that may be, online interventions are still a novel research area that struggles in implementation. Objectives: This study aims to determine the acceptability, feasibility, and efficacy of Oncovox, an iACT-BC, a guided internet delivered ACT intervention designed to improve psychosocial outcomes in BCP diagnosed within the last two years when compared to treatment as usual. The primary outcomes in this study are health related quality of life, behavioural activation, symptom interference and reward observation. The secondary outcomes are psychosocial distress, anxiety and depression and psychological flexibility. Methods: A two-arm, parallel, open label, waiting list randomised controlled trial will investigate the effectiveness, feasibility, and acceptability of Oncovox. Expected results: It is anticipated that Oncovox will show to be effective, feasible and acceptable programme in improving health related quality of life, behavioural activation, symptom interference, reward observation, psychological distress, anxiety, depression, and psychological flexibility in BCP diagnosed in the last two years, as opposing to a waiting list control under treatment as usual. An exploratory moderator analysis will be employed to the assess the significance of Time x Group as well as Time x Group x Surgery type interactions for all outcome and process variables. A mediation analysis to assess the effect of psychological flexibility on the outcomes will also be applied. The results of this research will be published in accordance with CONSORT 2010 and CONSORT-EHEALTH guidelines and should be available for publication in September 2022.
Cancer survivorship is associated with many long-term chronic health issues that arise as a result of cancer treatment protocols. Non-pharmacological lifestyle and mind-body interventions have been shown to be effective and critical components of a total-health strategy for cancer survivors. PranaScience Institute seeks to develop and test a novel group video app for home-based delivery of a Yogic Breathing intervention that reduces symptoms of cancer treatment survival and supports total-health.
This is an open-label, multi-center, roll-over study to evaluate the long term safety of ribociclib in combination with other drugs in participants who are participating in a Novartis sponsored global study, that has fulfilled requirements for its primary objective(s), and who in the opinion of the Investigator, would benefit from continued treatment.
In this study, the safety, tolerability and preliminary effectiveness of GNC-035 in participants with locally advanced or metastatic Breast Cancer will be investigated to assess the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) or maximum administered dose (MAD) for MTD is not reached of GNC-035.
Italian Multicentric non inferiority two-arm randomized clinical trial to verify that the experimental treatment (omission of axillary lymph node intervention) in the presence of sentinel lymph node metastases does not lead to a significant worsening in survival or in the risk of locoregional recurrence compared to standard treatment (removal of I-II level of axillary lymph nodes).
The primary objective of this Phase 2 Simon 2-Stage study is to determinate the Overall Response Rate (ORR) per RECIST v1.1 following treatment with Imprime PGG + pembrolizumab in patients with ER/PR+/ HER2(-) metastatic breast cancer who have progressed through prior hormone therapy with at least one CDK4/6 inhibitor, and a maximum of 2 subsequent chemotherapy treatment. Patients will be screened for baseline anti-β glucan antibody level (ABA; measured in peripheral blood). Those patients with an ABA greater than or equal to 20 mcg/ml and meeting all other I/E criteria, will be enrolled. The study will enroll 47 patients with 23 patients enrolled into Stage 1. If 4 or more patients in Stage 1 have an objective response after 12 weeks of treatment, the study will proceed into Stage 2. A total of 24 patients will be enrolled in Stage 2 for a total combined population of 47. Overall, objective responses must be observed in 10 patients for the study to be declared a success.
This is a Phase 1 dose-escalation and confirmation study of PRT2527, a Cyclin-dependent Kinase 9 (CDK9) inhibitor, in participants with advanced solid tumors. The purpose of this study is to define the dosing schedule, and maximally tolerated dose to be used in subsequent development of PRT2527.
This project intends to prospectively collect patients with suspected breast malignant tumors by ultrasound or mammography. After routine MRI scanning, all patients underwent diffusion spectrum imaging (DSI) sequence scanning. The inclusion criteria were as follows: (1) breast cancer was confirmed by surgery or biopsy. (2) pathologically diagnosis of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor 2 (HER-2), Ki-67, and lymphatic vessel invasion (LVI) status in breast cancer. (3) routine MRI and DSI scans were performed within one week before the pathologic examination. The exclusion criteria were as follows: (1) patients who had received treatment before DSI scanning; (2) patients who underwent breast tumor biopsy within two weeks before DSI image acquisition; (3) pathology results of breast masses were other diseases besides breast cancer. (4) post-processing of DSI data cannot be performed due to poor image quality, such as motion artifacts. Breast MRI data were collected on a 3T MR scanner (Magnetom skyra, Siemens Healthcare, Erlangen, Germany). All participants used standardized breast MRI scanning schemes, including T2 weighted imaging (T2WI), T1 weighted imaging (T1WI), diffusion-weighted imaging (DWI), DSI, and contrast dynamic enhancement (DCE). A total of 22 GSI quantitative parameters were derived from NeudiLab software that is based on the open-source platform DIPY (diffusion imaging in Python, http://nipy.org/dipy). The correlation between DSI quantitative parameters and pathological indexes (i.e., ER, PR, HER-2, Ki-67, and LVI) was evaluated by Spearman correlation analysis. The independent predictors of GSI quantitative parameters for different pathologic characteristics discrimination in breast cancer were determined by the logistic regression analysis. The predictive performance of DSI quantitative parameters for difference pathologic classifications was assessed by the receiver operating characteristic (ROC) curves and their respective area under the curves (AUCs).
