1. Breast cancer patients and age-matched controls are first invited to answer questions on HRQoL. 2. Among responding breast cancer patients, a subset are invited in a randomized clinical trial with two digital interventions for cancer stress management, cognitive based stress management (CBSM) and mindfulness based intervention (MBI), as well as a control group. 3. The goal is to determine whether digital CBSM or MBI can effectively reduce stress levels as compared to a control group. Second, whether these interventions can improve HRQoL (or avoid onset of HRQoL problems) for patients with breast cancer, compared to a control group.
The present study aimed to verify the effects of resistance exercise training and successive detraining on body composition, lipid profile, muscle strength, oxidative stress, and inflammatory markers of postmenopausal breast cancer survivors undergoing tamoxifen treatment.
The challenge of breast conserving surgery (BCS) is to obtain free resection margins, by removing the invasive tumor and the precursor cells: DCIS (Ductal Carcinoma in Situ). Consequently, 17%-25% of primary invasive breast cancer patients will need a repeat surgery. Repeat breast surgery has been associated with higher surgical risks, poorer cosmetic outcome and increased psychological and economic burden. Finding a precise method to obtain tumor- and DCIS-free resection margins during BCS is therefore strongly needed. The purpose with this study is to investigate if the need for a re-operation can be reduced by performing Digital Breast Tomosynthesis (DBT) of the resected tumor margins compared to the currently used standard X-ray during BCS.
This is an open-label, two-part, phase 1-2 dose-finding study designed to determine the safety, tolerability, PK, PD, and proof-of-concept efficacy of ST101 administered IV in patients with advanced solid tumors. The study consists of two phases: a phase 1 dose escalation/regimen exploration phase and a phase 2 expansion phase.
Primary Objective: To determine whether Amcenestrant (SAR439859) in combination with palbociclib improves progression free survival (PFS) when compared with letrozole in combination with palbociclib in participants with estrogen receptor positive (ER+), human epidermal growth factor receptor 2 negative (HER2-) advanced breast cancer who have not received any prior systemic anticancer therapies for advanced disease. Secondary Objective: - To compare the overall survival in both treatment arms. - To evaluate the objective response rate in both treatment arms. - To evaluate the duration of response in both treatment arms. - To evaluate the clinical benefit rate in both treatment arms. - To evaluate progression-free survival on next line of therapy. - To evaluate the pharmacokinetics of amcenestrant, and palbociclib. - To evaluate health-related quality of life in both treatment arms. - To evaluate the time to first chemotherapy in both treatment arms. - To evaluate safety in both treatment arms.
The purpose of this study is to try to find a better injection regimen (including time and dose) of PEG-rhG-CSF, which is supposed to better prevent bone marrow suppression and/or FN in breast cancer patients who receive chemotherapy.
Hormone receptor-positive breast cancer accounts for about 70% of all breast cancers. Extended endocrine therapy with aromatase inhibitor is the current main treatment for hormone receptor-positive breast cancer. However, previous studies have shown a long-lasting risk of the recurrence of hormone receptor-positive breast cancer at early stage, and disease recurrence is considered inevitable only depending on a 5-year of adjuvant endocrine therapy. Therefore, extended endocrine therapy is considered as a possible measure to reduce the risk of recurrence. Numerous clinical studies have focused on extended endocrine therapy in patients with specific types of breast cancer. In 2017, the National Comprehensive Cancer Network (NCCN) updated the recommends for extended endocrine therapy with aromatase inhibitor, where postmenopausal early-stage breast cancer patients wo have high risk factors may be considered to be given an extended 5-year endocrine treatment with aromatase inhibitor after the initial 5-year treatment. In 2019, the Chinese Society of Clinical Oncology also suggested that postmenopausal hormone receptor-positive patients who have been well tolerated to the initial 5 years of adjuvant endocrine therapy can be given the extended endocrine therapy under some restrictions. However, extended endocrine therapy may also cause other risks in patients. Long-term tamoxifen treatment can significantly increase the incidence of adverse reactions such as endometrial cancer, thrombotic disease, and dyslipidemia, and long-term aromatase inhibitor treatment can also increase the incidence of osteoporosis, fractures, dyslipidemia, and hypertension. Although anti-cancer treatment can reduce cancer deaths, it may increase deaths due to cardiovascular diseases. An attempt has been proposed to find out an indicator that can effectively determine the necessity of extended endocrine therapy in such patients, not only improving the prognosis of breast cancer patients, but also reducing treatment-related side effects. The author's team recently discovered sj-subway, a possible factor with a long tubular structure in breast cancer lesions. The authors found that the higher expression of sj-subway indicates the worse patient's prognosis. So the positive expression of sj-subway may be a predictor of recurrence and metastasis in high-risk hormone receptor-positive patients. However, whether this predictor can be used clinically remains to be studied. This real-world study intends to analyze the difference in the clinical efficacy of extended endocrine therapy under different sj-subway expression in high-risk hormone receptor-positive breast cancer patients, and to explore whether sj-subway can screen out the patients who can benefit from extended endocrine therapy, thus providing a therapeutic help for hormone receptor-positive breast cancer patients.
This clinical trial examines the integration of cancer genetic testing in various ethnic populations. Studying individuals and families at risk of cancer may help identify cancer genes and other persons at risk. The information from this study may provide an opportunity for cancer risk stratification and individualized screening in these ethnic populations.
The primary aim of this study is to determine if the addition of an individual polygenic risk score (PRS) in addition to the Breast Cancer Risk Assessment Tool (BCRAT) or Tyrer-Cuzick (IBIS) score will aid women at risk of breast cancer in making a decision to take (or not take) medications to prevent breast cancer.
