Filter by:Neoadjuvant chemotherapy (NACT) can induce complete pathologic response (pCR) in approximately 35-55% of patient with triple-negative breast cancer (TNBC). These patients have excellent long term survivals. On the other hand patients with residual disease exhibit a high rate of local or metastatic. Although it has been successful in some regards, randomized trials have shown similar rates of mortality between patients receiving NACT and adjuvant chemotherapy (ACT). The goal of this study is to understand the molecular biology (gene expression signature) driving treatment-resistant TNBC. The investigators are planning to identify targetable genetic alterations which may help to optimize adjuvant therapy for the patient with residual TNBC.
This is a companion study to the "Pragmatic Randomized Trial of Proton vs Photon Therapy for Patients with non-Metastatic Breast Cancer Receiving Comprehensive Nodal Radiation: A Radiotherapy Comparative Effectiveness (RadComp) Consortium Trial" (NCT02603341). The investigators will collect cardiovascular (CV) biomarkers and echocardiograms prior to, during, and for up to 1 year following radiation for a subset of patients enrolled on RadComp and to evaluate the impact of proton vs photon radiation therapy (RT) on CV function and structure.
This clinical study is aiming to determine the safest doses and schedule for the combination of two drugs named palbociclib and avelumab. The study will also be investigating how effective the combination is for a subgroup of breast cancer patients whose cancer expresses the androgen receptor (AR) but not the oestrogen (hormone) or HER2 receptors. Palbociclib is a drug used in routine care for hormone-receptor (HR) positive and HER2 negative advanced breast cancer, the most common subtype of breast cancer. It is possible that the combination of palbociclib and avelumab will be a more effective cancer treatment than each drug separately, but this is unknown and this study is needed to establish the best dosage and schedule of each drug as well as how effective the combination is.
To evaluate and compare the sensitivity, specificity, AUC, pathology results of core needle biopsy and surgical pathology results coincidence rate, tumor staging, and DFS (disease-free survival) of US-detected nonpalpable breast cancer vs mammography-detected nonpalpable breast cancer.
The purpose of this study is to find the most effective dose of radiation therapy to give to breast tumors in a shorter period of time, prior to standard partial mastectomy/axillary surgery.
This study aims to identify key benefits and harms of integrating risk stratification (the BC-Predict intervention) into the NHS Breast Screening Programme. A non-randomised fully counterbalanced study design will be used, whereby women from screening sites will be offered usual NHS Breast Screening Programme or BC-Predict for an eight month period, followed by a cross-over point where women at each site will be offered the other invention during an eight month period.
.Brief Summary:* Obesity is a major public health problem in France. Indeed, 17% of the French population is obese (BMI greater than or equal to 30 kg/m²) while almost half of the adult population is overweight (BMI greater than or equal to 25 kg/m²). There is an increased risk of gynecological cancer in obese women but screening is less often performed : In women, obesity is a risk factor for the occurrence of certain cancers such as uterine cancer, epithelial ovarian cancer and breast cancer, particularly post-menopausal. In addition, an increase in BMI from the first stage of obesity is associated with larger breast tumors with more frequent lymph node involvement, indicating more invasive cancers. Recent studies have shown an increase in breast cancer mortality for women with grade 2 and 3 obesity compared to women of so-called normal weight. Mortality from invasive breast cancer is higher from the obesity stage onwards. The current recommendations of the High Authority for Health recommend breast cancer screening by mammography and clinical examination every two years in all women aged 50 to 74, excluding women at high risk and requiring specialist follow-up. Organized screening for cervical cancer has recently been modified. From 25 to 30 years of age the modalities remain the same and consist of two cytological examinations one year apart and then every 3 years if the latest results are normal. From the age of 30 and up to the age of 65, it is now recommended that an HPV test be performed as a first-line test, 3 years after the last normal cytological examination and then every 5 years if the last test was negative. Studies dating back quite some time had shown an under-screening of cancers in obese women, in terms of carrying out mammography and cervical smears compared to women of normal weight. More recent data on access to gynecological cancer screening for obese women are heterogeneous, but there still seems to be less access to these examinations, whether for mammography or cervical smears. For example, a large American cohort study observed poorer detection of pre-cancerous lesions by smear with increasing BMI. Obese women had the lowest cumulative risk of pre-cancerous lesions at five years (followed by overweight women), but the highest rate of cancer at five years, associated with higher mortality. A neglected contraception in obese women? Data in the literature show that rates of unintended and unplanned pregnancies are higher in obese women (mainly those with grade 3 obesity) than in normal-weight women. This is associated with a lower use of contraception which is certainly poly-factorial: contraception not necessary due to a decrease in fertility linked to obesity, increased risks linked to contraception in obese women... However, most current contraceptive methods have shown similar efficacy in obese and non-obese women. This context suggests that there is still a marked difference in the gynecological management of obese women. The role of the general practitioner seems essential in this follow-up by facilitating the use of screening tests and by improving the information of this population with regard to contraception in particular. The objective of this study is to compare the gynecological follow-up of obese and non-obese women in a sample of women in Occitania, in terms of screening for breast and cervical cancer, as well as in terms of access to a method of contraception in general practice.
This study is a prospective, single-center, open-label, umbrella-shaped phase II clinical study for patients with HR+/HER2- endocrine-resistant advanced breast cancer.
This is a open-label, multicenter phase Ib study to evaluate safety and efficacy of TQ-B3525 tablets combined with fulvestrant injection in subjects with HR-positive, HER2-negative and PIK3CA mutation advanced breast cancer.
The purpose of this study is to help better understand the uptake and impact of genetic testing for women diagnosed with breast cancer who do not meet National Comprehensive Cancer Network (NCCN) criteria for genetic testing. By doing so, the research team will gain a better understanding of the clinical implications for offering genetic testing for all patients recently diagnosed with breast cancer versus only offering genetic testing to those meeting NCCN criteria. By offering genetic counseling and genetic testing to all women recently diagnosed with breast cancer, there will be a shortage of genetic counselors. This study will also assess the feasibility of using artificial intelligence to assist in the genetic counseling process.
