Filter by:Chemotherapy treatments such as epirubicin-cyclophosphamid or paclitaxel lead to severe off-target side effects such as skeletal muscle deconditioning. To date, three different studies investigated skeletal muscle decontioning in breast cancer patients, through long term protocols including all chemotherapy cycle treatment, and highlighted both structural alterations and impaired cellular processes. However, no study is currently availbale on the acute effect of one single chemotherapy administration in breast cancer patients skeletal muscle tissue. Our study is therefore dedicated to the investigation of the acute effect of the first dose administration of both Epuribicin/cyclophosphamide and Paclitaxel chemotherapies on skeletal muscle of breast cancer patients.
This is a retrospective propensity score-matched analysis of a large institutional cohort of patients in order to compare long-term outcomes and clinicopathologic characteristics between patients treated with breast conserving surgery or mastectomy for breast cancer.
Rationale: In breast cancer, a sentinel node procedure is performed to investigate whether malignant cells have spread to the axillary lymph nodes. This is an important part of determining the stage of breast cancer and the final treatment plan. A disadvantage of the sentinel node procedure is that it is performed using radioactive tracing with concomitant radiation exposure for the patients and involved health care personnel. In addition, the use of radioactive tracing puts high demands on the logistics in the operation theatre: the capacity of patients that can be treated in one day is limited and the radio-active tracing leads to many time-consuming precautionary measures. A radiation free alternative would therefore have multiple advantages. Not only with respect to radiation exposure for the patients and health care workers, but also by reducing the waiting time for operation for the patients as it will make the planning of patients for surgery more efficient. Recently, a radiation free tracer for the sentinel node procedure has become available (Magtrace). This tracer has been tested in small-case studies and is currently used as standard care in several hospitals around the world. Objective: The primary objective of this study is to evaluate the diagnostic accuracy of Magtrace in the sentinel node procedure in breast cancer in the Breast Care Centre in Zuyderland Medical Centre; with the ultimate goal to make the sentinel node procedure a radiation free process. Study design: A prospective cohort of forty patients with breast cancer and an indication for a sentinel node procedure will be injected with both Technetium (radioisotope) and Magtrace (magnetic). All patients in this study will receive both tracers. Study population: Patients of 18 years or older with breast cancer and an indication for a sentinel node procedure will be included. These patients will be recruited by their breast surgeon in the outpatient department of the Breast Care Centre in Zuyderland Medical Centre. Intervention (if applicable): Sentinel node procedure using a magnetic tracer next to Technetium. Main study parameters/endpoints: The concordance in detection of sentinel nodes by Magtrace and the Technetium tracer, measured by the sensitivity and specificity of Magtrace in detecting sentinel nodes with Technetium tracer as gold standard. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The goal of this project is evaluating the diagnostic accuracy of Magtrace in the sentinel node procedure. To establish that Magtrace is a non-inferior and a non-radioactive alternative for Technetium with respect to reliability in detecting metastases. The ultimate goal is to make the sentinel node procedure a radiation free process.
Up to 78% of women diagnosed with breast cancer experience impairments in their cognitive function (e.g., frequent forgetfulness, slow processing speeds, and difficulties in concentration, multitasking and/or word retrieval) in the course of cancer treatment. These cognitive impairments (CI) have negative effects on patients' social relationships, overall life satisfaction, and treatment adherence. Dietary intake may be an important factor in mitigating risk of CI that breast cancer patients experience. Several studies have suggested that dietary intake of specific nutrients and foods (e.g., carotenoids, B-vitamin, and omega-3 fatty acids rich foods) can be helpful to decrease the severity of cancer-related cognitive impairment (CRCI). High-quality dietary patterns can be also helpful to protect white matter volume and its integrity; damage to and changes in white matter contributes to CRCI. However, despite the high incidence of CRCI in breast cancer patients, very little is known about etiology of CRCI. Thus, the purpose of this observational study with cross-sectional design is to examine the relationships of diet with brain structural and functional outcomes of breast cancer patients. The study will aim to enroll 30 female postmenopausal breast cancer survivors (age 45-75) who have recently completed chemotherapy treatment within 3-12 months from study enrollment. Participants will complete study questionnaires online, and will have an in-person study visit to complete a functional magnetic resonance imagine (MRI) scan, cognitive testing, and blood sample collection via fingerstick and venous blood draw. It is expected that this study will advance the field's understanding and ability to early assess, manage, and prevent CRCI.
This study aims to evaluate the effectiveness of Aquatic Therapeutic Exercise by providing a set of exercises in the reduction and / or control the volume of secondary lymphedema treatment of breast cancer in patients who are in the maintenance phase of conventional treatment. It is an experimental, randomized, unifactorial, and intersubjective study. The intervention group will be treated by guided underwater exercises while the control group will receive the same set of exercises out-of-water. The research will be based on comparing the difference on the volume of lymphedema obtained by the exercises provided aquatic environment and out-of-water exercises. The study population will be obtained from rehabilitation service Bellvitge Hospital. The goal is to evaluate the volume of lymphedema and the quality of life related to the health of patients will be evaluated before starting the treatment, at the end of the 20 sessions, when the treatment reaches 3 months and when patient is discharged.
Study to assess the capability of using the Histolog Scanner, a recent large field-of-view confocal laser scanning medical imaging device for the breast cancer detection in fresh lumpectomy margins.
The purpose of this study is to conduct a descriptive feasibility study of assessing how patients retain and understand information regarding radiation therapy obtained from an initial consult visit. This study will also pilot the use of visual aids and assess their utility to patients during a consult. The study will provide a baseline to conduct larger studies that will later incorporate additional patient education tools to assess changes in patient understanding of information received in radiation oncology patient consultations.
The purpose of this study is to evaluate the mechanism of action, as well as the safety and efficacy of trilaciclib in combination with standard of care treatment in the neoadjuvant setting of early-stage triple negative breast cancer (TNBC). This study will have four phases: 1) Screening Phase, 2) Trilaciclib Lead-In Phase, 3) Treatment Phase, and 4) Surgery and Follow-Up Phase. After a screening phase of up to 21 day, each participant will receive trilaciclib single-dose monotherapy during the lead-in phase, followed by a tumor biopsy. During the treatment phase, each participant will receive trilaciclib with standard of care chemotherapy. Immunotherapy may be included during the treatment phase, per standard of care. 3-5 weeks following conclusion of the treatment phase, each participant will undergo definitive surgery. A 30-day Safety Follow-up Visit will occur 30 days after the last dose of trilaciclib and an End of Study Visit will occur within 14 days after definitive surgery.
This is a multicenter, randomized, open-label, active comparator-controlled phase Ⅲ trial to compare efficacy and safety of Goserelin Acetate Sustained-Release Microspheres for Injection (LY01005) and ZOLADEX® in patients with breast cancer.
Patients with breast cancer meet criteria for enrollment are randomized into PTC group or control group. The neoadjuvant therapy regimens are guided by PTC test in the PTC group. The regimens in control group are included of (dd)EC-T for HER2 negative subtype, TCH(P) or EC-TH(P) for HER2 positive subtype. We compared the pCR rate between two groups as the primary endpoint.
