Filter by:Purpose To investigate the ability of 18F-FDG PET/CT imaging to detect metastases not detected by conventional imaging (CT and bone scintigraphy) in patients diagnosed with stage II/III and locoregional recurrent breast cancer (BC) which can affect the choice of treatment. Hypothesis The hypothesis is that 18F-FDG PET/CT can provide information about disease stage beyond the currently used conventional imaging (CT and bone scintigraphy) in patients diagnosed with stage II/III or locoregional recurrent BC. Objectives Primary: To evaluate if a 18F-FDG PET/CT scan in the initial work up of patients diagnosed with stage II/III or locoregional recurrent BC will lead to change in staging and/or treatment. Secondary: - Overall survival (OS) and progression-free survival (PFS) in the patients with upstaging based on findings on 18F-FDG PET/CT scan compared with the patients with unchanged stage of disease following 18F-FDG PET/CT. - Obtain size of the primary BC from CT/MRI scan and evaluate if these metrics are correlated to outcome. - Obtain PET parameters from the primary BC: maximum, mean, and peak standardized uptake value (SUVmax, SUVmean, SUVpeak), metabolic tumour volume (MTV), total lesion glycolysis (TLG), total MTV and total TLG and evaluate if these metrics are correlated with outcome. - Obtain CT and PET texture parameters from the primary BC and evaluate if these metrics are correlated with outcome. - Blood and tumor samples for molecular characterisation:
This study will examine how ctDNA and additional prognostic genomic information in patients with early stage breast cancer might influences patient decision- making regarding systemic therapy options.
The aim of this observational study is to investigate the association between mid-life changes in cardiorespiratory fitness and the risk of breast cancer incidence and mortality among Swedish women. The main questions to answer are: - Are changes in cardiorespiratory fitness associated with the risk of being diagnosed or dying from/with breast cancer later in life? Participants performed at least two occupational health assessment tests, which consisted of a submaximal ergometer cycle test, measurement of body mass and height to calculate BMI, and a questionnaires on physical and life style habits.
Studies have shown that dose-dense chemotherapy reduces the risk of recurrence and death of breast cancer patients comparing with standard-schedule chemotherapy. But some research data indicate that HR+/HER2- breast cancer patients benefit from dose-dense chemotherapy while some have negative results. How to identify HR+/HER2 breast cancer patients who are more likely to benefit from dose-dense chemotherapy is strongly necessary. Ki67 is a marker reflecting the proliferation of tumor cells. Breast cancer patients with high Ki67 are more likely to benefit from dose-dense chemotherapy. The purpose of this project is to investigate the efficacy and safety of neoadjuvant dose-dense chemotherapy for HR+/HER2- breast cancer patients with high proliferation index. At the same time, we will explore biomarkers, such as MammaPrint and BluePrint, to further identify patients who benefit more from neoadjuvant dose-dense chemotherapy.
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.
Postoperative radiotherapy is for the majority of breast cancer patients the standard of care. During postoperative radiotherapy, unexpected dosimetric deviations can occur due to breast contour changes resulting from resorption of postoperative breast or chest wall seroma/hematoma, oedema either postoperatively or during irradiation, or arm/body positioning variation. In approximately 10% of cases, repositioning after setup imaging is not sufficient, and offline plan adaptation is required. When a new treatment planning is required in the standard offline workflow this will take in general 2 days. By using an online adaptive workflow with a daily treatment planning this delay and extra work caused by offline plan adaptation can be omitted. The aim of this study is to translate the offline adaptive workflow to an online adaptive workflow, and investigate the experiences of patients who have been treated with online adaptive radiotherapy for breast cancer (BREAST-ART).
The purpose of the study will be to investigate the effect of kinesotaping augmented by resistive exercise on fatigue, muscle strength, and QoL in breast cancer survivors.
To establish if the cardiac radiation dose assesment is well aproximated with routine 3D CT scan compared to 4D CT experimental scan with respiratory gating (breath motion monitoring). The study population relates to left side breast cancers female patients that require a radiation therapy treatment.
To evaluate the efficacy and safety of Disitamab Vedotin combined with Penpulimab as neoadjuvant therapy in patients with HER2-low early or locally advanced breast cancer
This study is conducted to compare between efficacy of large and small area of low-level laser therapy (LLLT) in treatment of post mastectomy lymphedema. The change of severity of BCRL will be measured by the difference of circumference and skin thickness, detected by ultrasound. The influence on clinical symptoms, such as pain, shoulder mobility and hand function, are also investigated in the study.
