Filter by:This pilot observational study is being done to identify possible biomarkers of response to endocrine therapy in patients with ER/PR+ metastatic lobular breast cancer (LBC) starting new endocrine therapy. 18F-fluorofuranylnorprogesterone Positron Emission Tomography/Computed Tomography (FFNP-PET/CT) and liquid biopsies will be performed at baseline and after 4 weeks of treatment. Baseline levels and dynamic on-treatment changes in estrogen signaling as measured by FFNP-PET/CT and circulating tumor cell (CTC) liquid biopsy will be correlated with clinical response to endocrine therapy and progression-free survival in the above cohort of patients.
Study hypothesis is that combining the advantages of hybrid PET/MRI and the high sensitivity/specificity of 16-alpha-18F-fluoro-17-beta-estradiol(FES), a radiolabeled form of estrogen binding to functionally active ER, the investigators could obtain a reliable, non-invasive, operator-independent, one-stage imaging method for staging LumA and ER-positive Lobular tumours.
This is a prospective observational registry for patients with invasive lobular carcinoma (ILC) of the breast. After the first 1cohort is enrolled, the collected data will be utilized to develop an ILC specific response assessment tool.
Lobular Breast cancer staging with 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) is not optimal due to the poor accumulation of 18F-FDG in the tumour. Through better sensitivity (and specificity), 68Ga-FAPI-46-46 PET should provide a more accurate staging of lobular breast cancer than 18F-FDG PET.
The purpose of this study is to find out whether lattice radiation therapy (LRT) is an effective radiation therapy technique when compared to standard stereotactic body radiation therapy (SBRT). The study will also study how the different radiation therapy techniques (LRT and SBRT) affect how many immune cells are able to attack and kill tumor cells (immune infiltration).
This is a cross-sectional and retrospective study of a cohort of patients with invasive lobular breast cancer (LBC) or in situ lobular neoplasia (LIN3). The main endpoint is the relative frequency of patients with a germline mutation using a recent panel including 113 genes from the "Illumina" protocol. In case of identification of a novel pathogenetic germline mutations, a personalized follow-up will be offered to each patient (in case of genes at moderate-, low-penetrance), or prophylactic mastectomy (in case of genes at high-penetrance). Breast screening in moderate-, low-penetrance mutated patients should be performed periodically using digital mammography, ultrasound and MRI, and will be routinely observed. Patients will be scheduled for follow-up at six-month intervals for 5 years at our outpatient clinic, and yearly thereafter
Invasive lobular breast carcinoma (ILBC) represents 5-15% of all invasive BCs. The CDH1 gene (OMIM no. 192090), located on the chromosome 16q22.1, encodes for the E-cadherin protein, a key regulator of cell adhesion. Loss of E-cadherin expression is frequently detected in LBC CDH1 germline loss-of-function mutations are associated with the autosomal dominant cancer-predisposition syndrome, hereditary diffuse gastric cancer (HDGC; OMIM no. 137215). The cumulative risk of LBC for women with a CDH1 mutation is estimated to be 42% (95% CI 23% to 68%) by 80 years, when it is a component of HDGC syndrome. Recently, some authors described CDH1 germline mutations in women with in situ or ILBC with early onset (<45 or <50) and bilateral in situ or ILBC with no family history of HDGC. These results are opening a new scenario, suggesting that CDH1 could be a susceptibility gene for LBC in women without a family history of DGC. The first aim of this study is to investigate prevalence of CDH1 in this specific population of women with early onset (<45 or <50) in situ or ILBC, bilateral LBC or LBC with no family history of HDGC.
Decision making about whether to have breast reconstruction after mastectomy can be difficult, and previous studies have found that many women are not well informed about their options. Patient decision aids can improve decision quality for a variety of health conditions. This pilot randomized study seeks to determine how a patient decision aid about breast reconstruction affects the quality of decisions about reconstruction including patient knowledge, concordance between preferences and treatment, and decisional regret.
The purpose of this study is to find out how effective the combination of crizotinib and fulvestrant is in shrinking lobular breast cancer tumours. The investigators will also be assessing the side effects of the combination of crizotinib tablets and fulvestrant injections. The side effects and the doses of crizotinib and fulvestrant have already been evaluated in large clinical trials, but this is the first time these two drugs will be combined together.
This randomized phase III trial studies how well hypofractionated radiation therapy works in preventing recurrence in patients with stage IIa-IIIa cancer who have undergone mastectomy. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells that remain after surgery and have fewer side effects.
