Filter by:The clinical trial is a phase 1, single-arm trial that will evaluate the safety of the investigational treatment on metastatic cancer in patients who have a deleterious or suspected deleterious BRCA1, BRCA2, or PALB2 genetic alteration. The investigational treatment will involve 2 cycles of a combination of intravenous melphalan, BCNU, low-dose I.V. ethanol, vitamin B12b, and vitamin C in association with autologous hematopoietic stem cell infusion. A dose-escalation schedule will be employed for vitamin C.
Robotic mastectomy with immediate reconstruction was introduced by Toesca et al. in 2015. Since then, several studies have reported the safety and feasibility of robotic nipple-sparing mastectomy with immediate reconstruction. However, most studies were conducted by single centers and had small samples. Furthermore, there is a lack of studies comparing surgical and oncologic outcomes between robotic nipple-sparing mastectomy and conventional nipple-sparing mastectomy. For this reason, this study evaluates surgical and oncologic outcomes of robotic nipple-sparing mastectomy with immediate reconstruction using international multi-center data.
IRFARPC is a multicenter national registry designed to study the diagnosis and predisposing factors of subjects with an inherited increased risk for pancreatic cancer.
This is a phase II/III randomized controlled trial to evaluate efficacy of platinum-based chemotherapy vs conventionally prescribed non-platinum monochemotherapy in patients with platinum-resistant ovarian cancer
Relationship between the presence of the BRCA mutation (BReast Cancer) and outcomes is unclear in high-risk early breast cancers (BC). This study is a multi-center retrospective cohort of patients treated in region Franche-Comté for an early BC by neoadjuvant and/or adjuvant chemotherapy. The primary aim was to describe clinical and pathological characteristics considering BRCA mutated (BRCAm) patients versus BRCA wild type (BRCAwt) patients or untested patients. The second objective was to assess the prognostic impact of germinal BRCAm in this high-risk population.
Risk-Reducing Salpingo-Oophorectomy (RRSO) at the age of 35 to 45 years is recommended for women with a high genetic risk for ovarian cancer. While this procedure decreases the risk of ovarian cancer by 80-96%, it also results in an immediate menopause. Current research on potential adverse effects of premenopausal risk-reducing salpingo-oophorectomy, such as increased risk of cardiovascular disease, compromised bone health, cognitive dysfunction and reduced quality of life, is limited, mostly due to short follow up. The investigators will conduct a multicenter cross-sectional study nested in a cohort of BRCA mutation carriers from 8 Dutch centers for hereditary cancer. Eligible participants are women who underwent RRSO before the age of 45. The participants will be frequency-matched on current age with women above the age of 55 without RRSO or with RRSO after the age of 55. Participants will complete an online questionnaire containing various questions about lifestyle, medical history, risk factors for cardiovascular disease, bone health, cognition and quality of life. Participants will be asked to visit one of the participating hospitals for a blood test, a cardiovascular assessment and a DEXA scan for determining bone mineral density. Afterwards participants will be requested to perform the online Amsterdam Cognition Scale.
The objective of this protocol is to develop an institution-wide liquid biopsy protocol that will establish a common process for collecting blood and corresponding archived tumor specimens for future research studies at the University Health Network's Princess Margaret Cancer Centre. Circulating cell-free nucleic acids (cfNA), including cell-free DNA (cfDNA) and cell-free RNA (cfRNA), are non-invasive, real-time biomarkers that can provide diagnostic and prognostic information before cancer diagnosis, during cancer treatment, and at disease progression. Cancer research scientists and clinicians at the Princess Margaret are interested in incorporating the collection of peripheral blood samples ("liquid biopsies") into research protocols as a means of non-invasively assessing tumor progression and response to treatment at multiple time points during a patient's course of disease.
The main purpose of this research study is to learn whether the investigational combination of olaparib, palbociclib, and fulvestrant is safe in patients with estrogen receptor-positive breast cancer and BRCA1 or BRCA2 mutations.
This is a combination retrospective/prospective observational study with two arms:
Women carrying harmful mutation in BRCA1 or BRCA2 gene are at higher risk to develop breast and/or ovarian cancer than the general population. Many observations lead to the hypothesis that breast cancer risk may be increased in women with elevated plasma insulin-like growth factor 1 (IGF-1) and insulin levels. Targeting the IGF system is therefore a promising anticancer therapy and a new tool for oncologists. Evidence from bio-gerontology research from our laboratories show that cycles of short-term fasting/starvation (STS) or low calorie diet can improve health span of laboratory animals, whose effect is partly mediated by reduced circulating IGF-1. Investigators in our group have demonstrated that protein consumption, especially animal proteins, increases IGF-1 level and is associated with elevated cancer risk in a US cohort ranging from age 50 to 65 (PMID: 26094889). It was also showed that alternating prolonged fasting and nutrient-rich medium extended yeast lifespan independently of the status of the established pro-longevity genes. Prolonged Fasting (PF) has also been shown in preliminary studies to decrease the side effects of chemotherapy, an effect now being tested in multiple larger randomized clinical trials (PMID: 26590477). The main hypothesis of this proposal is that a combination of protein restriction, fasting, fasting mimicking diet (FMD), and restriction of specific amino acids may be able to decrease cancer incidence in a cohort of people at high risk of developing tumors (BRCA1/2). Our group plan to verify the safety, effectiveness and impact of a specially formulated longevity dietary regimen (low protein fish- and plant-based) and of FMD repeated cycles on the levels of endogenous hormones in a cohort of people at increased cancer risk. Since the duration of the project will not give us the opportunity to directly measure cancer incidence in humans we will test: 1a) the variation of a number of widely recognized susceptibility biomarkers predictive of cancer incidence in a cohort human carriers of BRCA1/2 mutations in response to the dietary interventions; 1b) cancer incidence and progression in genetically engineered mice (K14Cre Brca1flox/flox Trp53+/flox and K14Cre Brca1+/flox Trp53-/- mice) predisposed to develop hereditary breast cancer in response to corresponding dietary interventions. Investigators will also test epigenetic alterations associated with these interventions in: 2a) DNA samples from muscle biopsies of a subgroup of humans; 2b) breast epithelial tissue in mice.
