Physical activity and exercise have demonstrated to be an integral part of the cancer-continuum care. Despite strong evidence suggesting that both endurance and strength training should be encourage in cancer patients, there is still controversy regarding exercise dosage, frequency, volume and optimal environment of delivery. In this randomised controlled trial we aim to compare water-based versus land-based exercise in breast cancer survivors to decrease cancer-related fatigue (CRF), improve Health-Related Quality of Life (HRQoL), exercise tolerance, muscle strength and physical activity levels.
Due to breathing and other motions, tumours, such as breast and lung cancer, as well as their surrounding organs (e.g. the heart), move, which poses a challenge for radiotherapy treatment. Reducing or even stopping breathing, e.g. by irradiating during inspiration, is a way to decrease tumour and organ motion resulting in a reliable target coverage with smaller margins. These smaller margins can result in a better sparing of normal tissues. Furthermore, in some patients, during inspiration, the heart may move away from the target volume making it possible to better spare the heart. Finally, during inspiration, the lung volume is larger and the lung density is lower, which can lead to a lower dose to the surrounding normal lung tissue. Reduction of radiation dose to normal tissues leads to less radiation-induced toxicity. This makes treating breast and lung cancer patients in breath hold (BH) conditions an attractive strategy. Standard BH durations in RT treatment are around 20 seconds, which is not enough to perform a complete CBCT. The health status of lung cancer patients is generally worse compared to breast cancer patients, making it more difficult to treat this patient group during breath hold. Nasal High Flow Therapy (NHFT) is a non-invasive system that provides controlled oxygen concentrations and low levels of positive pressure via a nasal interface. NHFT improves oxygenation in diverse patient groups, and is increasingly used as an alternative to mechanical ventilatory support. It has been shown to be a safe device in several clinical situations and patient populations, such as COPD patients, but also in apneic conditions under general anesthesia.
This study is aimed to establish a registry of women undergoing intensive surveillance for the early detection of breast cancer in high-risk women.
Accurate staging is of great importance in patients with clinically locally advanced primary breast cancer (LABC, stage III) or locoregional recurrent (LRR) breast cancer for making a correct treatment plan. According to current guidelines, staging is performed with positron emission tomography (PET) using the 2-[18F]fluoro-2-deoxy-D-glucose ([18F]FDG) PET tracer, combined with diagnostic computed tomography (CT). However, previous studies have shown that this technique (with the current PET tracer) might not be sufficient for accurate staging. Specifically in low grade, estrogen receptor positive (ER+) breast cancer metastases can be missed due to the low metabolic activity, leading to low uptake of [18F]FDG. Therefore, there is a clinical need to improve staging procedures. 16α-[18F]-fluoro-17β-estradiol ([18F]FES), an ER-targeted PET tracer, allows imaging of ER+ tumor lesions regardless of their metabolic activity. Patients with clinically LABC and LRR have a 25-50% risk of distant metastases. Correct identification of distant metastases allows adaptation of the treatment plan to avoid burdensome treatment with surgery, systemic and radiotherapy in order to maintain quality of life. In case of oligometastases, correct identification increases the likelihood for cure with local treatment. In the current study we will compare disease staging with [18F]FES- and [18F]FDG PET in patients with clinically LABC/LRR breast cancer. Objective: To determine whether [18F]FES PET/CT improves staging for women with clinically LABC or LRR, ER+/HER2- breast cancer as compared to standard [18F]FDG PET/CT. Study design: Multicenter prospective study with invasive measurements. Study population: 20 LABC and 20 LRR ER+/HER2- breast cancer patients. Main study parameters/endpoints: To determine the percentage of patients with a correctly changed treatment plan according to information obtained from [18F]FES PET/CT compared to [18F]FDG PET/CT at staging and at 6 months of follow-up; to determine the percentage of metastatic lesions detected and missed with [18F]FES PET/CT compared to [18F]FDG PET/CT (at staging and during follow-up). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Patients will receive an intravenous cannula for tracer injection and blood sampling, causing potentially transient discomfort at the site of the cannula insertion. Tumor biopsy will be performed from an easy accessible lesion and the most frequent complications that can occur are discomfort, bleeding and (local) infection. The risk of complications from a tumor biopsy is considered low: 0.24-1.6% and 0.11-0.48% for major complications and mortality, respectively. Radiation exposure from a [18F]FES PET and [18F]FDG PET scan usually ranges between 4-11 mSv and 7-8 mSv, respectively. Radiation exposure from a diagnostic CT scan ranges between 8-14 mSv. The total radiation burden is considered justifiable when compared to the information that can be obtained from this study, in this patient group with breast cancer. Imaging with [18F]FES PET may improve staging for patients with breast cancer as it may show tumor lesions that could not be identified with [18F]FDG PET, the current standard for staging. If this is the case, the initial treatment goal and intensity can be adjusted which can have beneficial effects for the patient.
This study (also known as IMpassion050) will evaluate the efficacy and safety of atezolizumab compared with placebo when given in combination with neoadjuvant dose-dense anthracycline (doxorubicin + cyclophosphamide) followed by paclitaxel + trastuzumab + pertuzumab (ddAC-PacHP) in patients with early HER2-positive breast cancer (T2-4, N1-3, M0).
This research is being done to learn more about whether or not Korean American women will improve the screening practices for breast and cervical cancer if subjects receive education and follow-up from community health workers. The education materials may be given via online or in-person. Primary Hypothesis: e-CHEC-uP will be as efficacious as the original CHEC-uP in promoting mammogram and Pap test screening among Korean immigrant women (KIW) at 6 months. Objectives: (1) To develop a web-based platform of the health literacy education component of the original CHEC-uP intervention; (2) To evaluate the acceptability and usability of the web version of the health literacy education in a user testing sample of 10 KIW; and (3) To conduct a pilot study to test the preliminary efficacy of the web version of CHEC-uP (e-CHEC-uP) in 40 KIW.
The purpose of this study is to assess the efficacy and safety of pembrolizumab (MK-3475) versus placebo in combination with neoadjuvant (pre-surgery) chemotherapy and adjuvant (post-surgery) endocrine therapy in the treatment of adults who have high-risk early-stage estrogen receptor-positive, human epidermal growth factor receptor 2-negative (ER+/HER2-) breast cancer. The primary study hypotheses are: 1) pembrolizumab is superior to placebo, both in combination with the protocol-specified neoadjuvant anticancer therapy, as assessed by pathological Complete Response (pCR) rate defined by the local pathologist, and 2) pembrolizumab is superior to placebo (both in combination with the protocol-specified neoadjuvant and adjuvant anticancer therapies) as assessed by Event-Free Survival (EFS) as determined by the investigator. The study is considered to have met its primary objective if pembrolizumab is superior to placebo with respect to either pCR (ypT0/Tis ypN0) or EFS.
