Active clinical trials for "Carcinoma, Lobular"

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.

This trial studies how well EMBr Wave technology works in reducing hot flashes in women with a history of breast cancer. Hot flashes are a common symptom experienced by menopausal women. The standard treatment for hot flashes is hormone replacement therapy, however hormone replacement therapy cannot be used in women with a history of, or active, breast cancer. EMBr Wave is a personal heating and cooling device worn on the wrist. EMBr Wave may help reduce hot flash severity in women with a history of breast cancer.

Circulating levels of Sex Hormone Binding Globulin (SHBG) are significantly associated with a decreased risk of breast cancer. The main aim of this clinical trial is to verify whether Low Dose Tamoxifen (LDT) increases circulating levels of SHBG more than lifestyle intervention (LI) with or without intermittent caloric restriction (ICR) after 6 months in women at increased risk of breast cancer (unaffected BRCA1-2 OR PALB2 mutation carriers; or with a >5% risk of developing breast cancer at 10 years according to the "Tyrer-Cuzick model") or with a recently resected intraepithelial neoplasia of the breast (IEN). The secondary aims are: to verify whether ICR significantly modulates primary and secondary endpoints such as Homeostasis Model Assessment (HOMA) index, immune and inflammatory markers, lipid profile, Adiponectin/Leptin (A/L) ratio, quality of life (QoL), Body mass index (BMI), fat body composition, safety and toxicity; to verify whether LDT significantly modulates secondary endpoints, such as HOMA-index, immune and inflammatory markers, lipid profile, A/L ratio, QoL, BMI, fat body composition, safety and toxicity; to investigate differences in microbiome composition by arms and the effect of changes in microbiome on QoL taking into account circulating biomarkers, cytokines, immune modulators, and inflammatory proteins in serum; to investigate MD (Mammographic Breast Density) changes by LDT vs. LI, with or without ICR. This aim will be performed in a subgroup of participants (not all the participants will undergo mammography due to younger age).

This phase IIA trial compares the effect of acolbifene versus low dose tamoxifen in preventing breast cancer in premenopausal women at high risk for developing breast cancer. The usual approach for patients at increased risk for breast cancer is to undergo yearly breast magnetic resonance imaging (MRI) or ultrasound in addition to yearly mammogram. Premenopausal women at very high lifetime risk for breast cancer (greater than 50%) can consider preventive removal (mastectomy) of both breasts. Premenopausal women age 35 or older with a prior diagnosis of atypical hyperplasia, lobular carcinoma in situ, or an estimated 10-year risk of greater than or equal to 3% or estimated 10-year risk of greater than or equal to 2-5 times that of the average woman (depending on age) may be advised to consider five years of standard dose tamoxifen. Standard dose tamoxifen is four times the dose used in this study. Estrogen can cause the development and growth of breast cancer cells. Acolbifene and tamoxifen blocks the use of estrogen by breast cells. This study may help researchers measure the effects of acolbifene and low dose tamoxifen on markers of breast cancer risk in mammogram imaging, breast tissue, and in blood samples.

This phase I trial studies how well fluciclovine positron emission tomography (PET)/computed tomography (CT) and PSMA PET/CT work in helping doctors understand and classify invasive lobular breast cancer in patients with invasive lobular breast cancer that is suspicious for or has spread to other places in the body (metastasized). Fluciclovine and PSMA are radiotracers used in PET/CT imaging scans that emit radiation. The PET/CT scan than picks up the radiation being released to create a picture from within the body. Information learned from this study may help researchers learn how to better identify metastatic disease in invasive lobular breast cancer patients which will impact appropriate staging.

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

This study evaluates whether adding a polygenic risk score evaluation to standard breast cancer risk assessment tools helps African American and Hispanic women make more informed decisions about accepting additional breast cancer screening and prevention strategies. Traditional breast cancer risk assessments rely mostly on the presence of standard clinical risk factors including family history, reproductive history, and mammographic breast density. This information can be combined with validated risk estimation models to provide a measure of a patient's 10 year and lifetime risk for breast cancer. A polygenic risk score helps to estimate breast cancer risk in a more individualized way by evaluating a patient's genetics. Adding a polygenic risk score evaluation to traditional screening techniques may help minority women make more informed decisions about screening and prevention strategies for breast cancer.

This research study is creating a way to collect and store specimens and information from participants who may be at an increased risk of developing cancer, or has been diagnosed with an early phase of a cancer or a family member who has a family member with a precursor condition for cancer. The objective of this study is to identify exposures as well as clinical, molecular, and pathological changes that can be used to predict early development of cancer, malignant transformation, and risks of progression to symptomatic cancer that can ultimately be fatal. The ultimate goal is to identify novel markers of early detection and risk stratification to drive potential therapeutic approaches to intercept progression to cancer.

This pilot clinical trial studies new ways to monitor the impact of hypofractionated image guided radiation therapy in treating patients with stage IV breast cancer. Radiation therapy uses high energy x rays to kill tumor cells. Giving radiation therapy in different ways may kill more tumor cells.

This phase II trial studies how well radiation therapy works in treating post-menopausal women with early stage breast cancer undergoing surgery. Radiation therapy uses high energy x rays to kill tumor cells. This may be an effective treatment for breast cancer.
