Filter by:This is a study to investigate the potential clinical benefit of G1T38 as an oral therapy in combination with fulvestrant in patients with hormone receptor-positive, HER2-negative metastatic breast cancer. The study is an open-label design, consists of 2 parts: dose-finding portion (Part 1), and expansion portion (Part 2). Both parts include 3 study phases: Screening Phase, Treatment Phase, and Survival Follow-up Phase. The Treatment Phase begins on the day of first dose with study treatment and completes at the Post-Treatment Visit. Approximately, 102 patients will be enrolled in the study.
This phase II trial studies how well talimogene laherparepvec and nivolumab work in treating patients with lymphomas that do not responded to treatment (refractory) or non-melanoma skin cancers that have spread to other places in the body (advanced) or do not responded to treatment. Biological therapies, such as talimogene laherparepvec, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop tumor cells from growing. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving talimogene laherparepvec and nivolumab may work better compared to usual treatments in treating patients with lymphomas or non-melanoma skin cancers.
In patients with resectable pancreatic duct adenocarcinoma (PDAC), curative surgery followed by adjuvant chemotherapy is currently the standard of care. However, the long-term results are still poor, with median disease-free and overall survival of 14 months and 23 months. The corresponding 5-year overall survival rate is 20%. Chemotherapy before surgery (neoadjuvant chemotherapy) allows identification of patients with rapidly progressive metastatic disease at time of preoperative restaging (surgery is then avoided in these patients), and may increase the rate of free margin resection (R0) and reduce the risk of local recurrence. Even though single-agent gemcitabine and 5-FU have been validated in adjuvant and metastatic settings, the objective response was low (at around 10%), whereas combination chemotherapy exceeds a response rate of 30% in advanced disease. In metastatic PDAC, palliative FOLFIRINOX chemotherapy has been demonstrated to be effective (in terms of response rates and progression-free survival) and well tolerated. Interestingly, the response rate is increased by using more than two chemotherapeutic agents in advanced pancreatic cancer, justifying the use of an alternative neoadjuvant FOLFOX-based chemotherapy arm. PANACHE-01 is an open, non-comparative, randomised, multicentre Phase II study designed to assess the safety and efficacy of two modes of neo-adjuvant chemotherapy (FOLFIRINOX & FOLFOX) relative to the current reference treatment (surgery and then adjuvant chemotherapy) for resectable PDAC. Patients with immediately resectable PDAC (definition based on the NCCN's (American National Comprehensive Cancer Network 2014) latest guidelines) will be randomised to either pancreatectomy and adjuvant chemotherapy or 4 cycles of neoadjuvant chemotherapy with either FOLFOX or FOLFIRINOX. The patients in the neoadjuvant chemotherapy arms will receive postoperative chemotherapy for 4 months (8 cycles).
This study is evaluating how ruxolitinib affects premalignant breast cells. One half of the study participants will receive ruxolitinib for approximately 15 days, and the other half will receive a placebo (sugar pill) for approximately 15 days. Once study participants have completed their ruxolitinib or placebo, participants will undergo surgery to remove the premalignant breast tissue.
This study looks at the risks and benefits of active monitoring (AM) compared to surgery in the setting of a pragmatic prospective randomized trial for low risk DCIS. Our overarching hypothesis is that management of low-risk Ductal Carcinoma in Situ (DCIS) using an AM approach does not yield inferior cancer or quality of life outcomes compared to surgery.
Mammography screening has limited performance in young women or women with dense breasts although it is the only proven method for breast cancer screening that reduces the mortality. The investigators propose a multicenter trial of breast cancer screening to assess the effectiveness of supplemental ultrasonography for Korean women aged 40-59 years.
Patients with ductal carcinoma in situ (DCIS) treated with available therapies have experienced excellent outcomes and very low mortality rates due to the disease's non-invasive nature. However, considerable debate exists as to how the DCIS lesion should be treated. As a result, determining strategies to manage DCIS has been identified as a research priority. The role of sentinel lymph node biopsy (SLNB) for DCIS management is controversial in general and needs further scrutiny. Our study addresses this evidence gap as the investigators propose a retrospective cohort study to investigate the outcome of SLNB among DCIS patients. Specifically, the investigators will compare the outcomes, including survival outcomes and treatment side effects, among women older than 67 years of age with DCIS receiving SLNB vs. not receiving SLNB within 6 months of DCIS diagnosis. The investigators have two primary aims in this study: Aim 1: the investigators select our study sample using SEER-Medicare database. The investigators will determine associations between SLNB and acute/subacute side effects, including lymphedema, pain, and limitation of movement of upper extremity from the first breast conserving surgery to 9 months post-diagnosis. Aim 2: the investigators will determine associations between SLNB and long-term outcomes, including breast cancer specific mortality, ipsilateral invasive breast cancer diagnosis, subsequent mastectomy as treated recurrence, and lasting side effects, from >9 months post-diagnosis to death or the end of this study period. Given the nature of our observational study design, the investigators will apply standard multivariate analyses and propensity score methodology to reduce the influence from confounders. The investigators will control for patient demographics, comorbidities, functional status, tumor characteristics, and prior healthcare utilization. Using distance to the nearest provider that uses SLNB for DCIS or surgeon's tendency in using SLNB for stage I/II breast cancer, the investigators also plan to conduct instrument variable analyses if necessary. Stratifying patients by key DCIS characteristics (including grade, comedonecrosis, and tumor size) and their predicted life expectancy (given their age and comorbidities), the investigators also hope to identify patient subgroups who may safely forgo SLNB. The study would provide evidence on the efficacy and safety outcome of SLNB for DCIS management.
The overarching purpose of this study is to determine if the mainstay chemotherapeutic regimens represented by several genotoxic agents including but not limited to Cyclophosphamide, Doxorubicin, Epirubicin, Fluorouracil and Methotrexate (CDEFM), in the format of either a single agent or combinations are safe, tolerable, and effective in the treatment of patients with infiltrating ductal carcinoma of breast.
Introduction: With population ageing and increasing Westernization breast cancer continues to be important health conditions among women in Hong Kong. Greater collaborative research efforts are needed to examine the questions about population screening for breast cancer, the aetiology of such lesions and outcomes of breast cancer during survivorship period. There is a lack of locally-relevant models for assessing breast cancer risk. Contribution of novel genetic factors to breast cancer, identification of the key and functional alleles in gene regions associated with risk of breast cancer as well as gene-environment interaction, requires further investigation in Chinese population. Prognostic research studies in the West may not be readily applicable to the Chinese population. Objectives: We aim to investigate the aetiology and outcomes of breast cancer in local Chinese by using case-control and cohort study design in the health care setting in Hong Kong. We aim to examine potential risk factors/biomarkers (both traditional and novel), and to build infrastructure and biobank for breast cancer surveillance. We will follow up cases prospectively as a survivor cohort. Methods: A hospital-based case-control study and a prospective survivor cohort study will be conducted. Consecutive incident breast cancer and DCIS cases (n=3,501) within a 36-month period in Hong Kong were recruited from public hospitals, private hospitals and private practices; and controls were selected by frequency-matching on factors such as age and hospital/clinic setting, whenever possible. Cases will be prospectively followed up over a 10-year period, and data collection will occur at baseline (within 24 weeks of diagnosis), 3, 5 and 10 years following baseline assessment. Biologic samples (including both blood, and tumour and normal breast tissue samples from the cases, and blood samples from the controls) will be collected for later genetic and molecular study including WGS, GWAS, gene-environment interaction and molecular functional studies. Depending on availability of pathology samples and resources, additional studies such as tissue microarray block production will be considered and performed in future. Data will be analysed by traditional regression, EWAS and genetic association methods, whenever relevant. Public Health Implications: The repository of clinical, radiological and biological materials assembled through this case-control study will serve as a common, publicly accessible platform for subsequent functional analysis and scientific interrogation. The case-control findings would offer an improved understanding to the state of the science on aetiology of breast cancer in Chinese women. In the genomics analysis, potential refined classification of breast tumours may enhance our understanding, detection and follow-up of such lesions, as well as enable us to have more informed targeted and personalized treatment selection for our women population. The cohort study findings are important for developing an effective strategy for the improvement of overall survival and quality of life for the cancer survivors in Chinese population.
This phase 1b trial studies the biologic effect of 9cUAB30 on early stage breast cancer. 9cUAB30 is a retinoid X receptor (RXR)-selective retinoid that acts in a tissue selective manner with the goal of minimizing side effects, a necessary feature of agents under development for cancer prevention.
