A Randomized Trial Evaluating Personalized vs Guideline-based Well Follow-up Strategies for Patients With Early-stage Breast Cancer

Start date: August 19, 2022
Phase: Phase 4
Study type: Interventional

After breast cancer patients complete the acute phase of their treatment (i.e. surgery, chemotherapy and/or radiation therapy), they are routinely followed in clinic every 3-6 months for several years. Multiple guideline recommendations exist with no consensus on the optimal follow-up schedule due to lack of randomized data to support any particular follow-up recommendation. Therefore the investigators propose a randomized trial evaluating personalized vs guideline-based well follow-up strategies for patients with early-stage breast cancer.

NCT ID: NCT05364450 Active, not recruiting - Breast Cancer Clinical Trials

Facilitating Adaptive Coping With Fear of Recurrence Among Breast Cancer Survivors

Start date: July 17, 2021
Phase: N/A
Study type: Interventional

Fear of cancer recurrence (FCR) is a highly prevalent, disruptive, and under-treated problem for breast cancer survivors. This randomized controlled trial will test the efficacy of group-based Acceptance and Commitment Therapy compared to Cognitive Behavioral Therapy and enhanced usual care for breast cancer survivors suffering from FCR while examining its cost-effectiveness and the mechanisms by which the intervention may work. Study findings will guide the future care of breast cancer survivors with FCR.

Sentinel Node Localization and Staging With Low Dose Superparamagnetic Iron Oxide

MAGSNOW
Start date: November 1, 2021
Phase: Phase 1/Phase 2
Study type: Interventional

Sentinel lymph node (SLN) status is pivotal for treatment decisions in breast cancer patients. The dual technique with Technetium99m (Tc99) and blue dye (BD) is yet the current routine for SLN detection. However, the same reliability has been presented by superparamagnetic iron oxide nanoparticles (SPIO). The aim of this study was to determine if SLN detection using ultra-low dose SPIO is feasible.

NCT ID: NCT05346224 Active, not recruiting - Breast Cancer Clinical Trials

Study type: Interventional

Study of NGM438 as Monotherapy and in Combination with Pembrolizumab in Advanced or Metastatic Solid Tumors

NCT ID: NCT05303129 Active, not recruiting - Breast Cancer Clinical Trials

Prognostic Impact of the Neutrophil/Lymphocyte Ratio (NLR) in the Treatment of First-line Metastatic or Locally Advanced Breast Cancer Treated With CDK4/6 Inhibitor.

PEPSI
Start date: May 27, 2022
Phase: N/A
Study type: Interventional

The impact of the inflammatory microenvironment in predicting the benefit of a CDK4/6 inhibitor in the treatment of locally advanced or first line metastatic breast cancer has not yet been studied. We propose a multicenter prospective study to confirm the prognostic value of pre-therapy NLR on progression-free survival of patients initiating treatment with a CDK4/6 inhibitor combined with hormonal therapy for locally advanced or metastatic HR-pos / HER2-neg breast cancer. We will also evaluate other markers of inflammation and their prognostic and predictive value for a better response to CDK4/6 inhibitor therapy in combination with hormone therapy in these patients. Specific blood tests (lymphocyte typing) will be performed during treatment with CDK4/6.

Tridimensional Geometric Modeling of the Breast

SENO3D
Start date: March 31, 2022
Phase: N/A
Study type: Interventional

The use of a personalized 3D model of the breast in the management of breast cancer would be very useful to help the surgeon better understand the three-dimensional location of tumors in the operative position and thus better plan incisions and dissection of the breast tissue. This could be achieved with the help of a 3D biomechanical breast model that ideally should integrate the patient-specific mechanical properties of all breast tissue structures. The elasticity of the skin and especially the consideration of factors that can make it vary with age has been little studied. However, the integration of this parameter would clearly increase the robustness of the 3D model. Main objective: To perform a pilot evaluation of the performance of the biomechanical model by integrating the biomechanical characteristics of the skin and the collagenous architecture of the breast, during the transition from prone to supine or lateral position. Secondary Objectives: To describe the values of skin elasticity and thickness at different points of the breast, in women in the general population To search for clinical factors predictive of elasticity and skin thickness To carry out a pilot description of the collagen architecture of the breast Participation in this study will be offered to all patients consulting the gynecology-obstetrics department of the Montpellier University Hospital and meeting the inclusion criteria-Visit 1: Inclusion and measurement of skin thickness and elasticity: Inclusion will take place during the follow-up consultation in the obstetrics gynecology department of the Montpellier University Hospital. The patient's written consent will be obtained after a reflection period at the end of the consultation. Measurements of elasticity and thickness will then be performed for each of the 200 patients. Skin elasticity: The patient will be installed in dorsal decubitus position, with her arms at her sides on an examination table. Measurements will be performed at 3 sites on one of the two breasts: at the areola, above the areola and below. The measurements will be performed by a single gynecologist in the gynecology department using a cutometer provided by a laboratory of Grenoble. It has just been used by the Dutch Cancer Institute in Amsterdam to measure the elasticity of the tongue in a clinical study including 10 patients. Three measurements will be performed at each site. One measurement corresponds to a 10-second suction time (progressive rise of the depression) followed by 5 seconds of relaxation of the measurement site. The duration of these measurements will be approximately 15 minutes. Skin thickness: The measurement of skin thickness will be performed using an ultrasound device available in the obstetrics and gynecology consultation department. The measurement will be performed at 3 sites. The duration of the measurements will be of approximately 10 minutes. Adverse events will be collected at the end of the measurements. -Visit 2: Within 3 weeks after the first visit. Among the 200 patients, 10 patients who should benefit from a breast MRI as part of their follow-up, will have a breast MRI in 3 different positions: prone (standard protocol) and two additional acquisitions (as part of the research) in dorsal and right lateral decubitus. This examination will be scheduled in the Lapeyronie Hospital.

Use of Superparamagnetic Iron Oxide (SPIO) in Sentinel Lymph Node Detection for Breast Cancer

Start date: July 24, 2018
Phase: N/A
Study type: Interventional

Sentinel lymph node biopsy is mandatory during breast cancer operation for disease staging and treatment. The localization of sentinel lymph node is by the injection of radioisotope and blue dye, which is the gold standard. However the use of radioisotope and blue dye are associated with specific drawbacks. Superparamagnetic iron oxide is a magnetic tracer which is FDA-approved for sentinel lymph node localization. The hypothesis of this study is superparamagnetic iron oxide can replace the conventional dual mapping of radioisotope and blue dye in the detection of sentinel lymph nodes for early breast cancers.

Interest of Virtual Reality on Anxiety Before the Planning CT Scan in Radiotherapy

REAVA
Start date: October 5, 2022
Phase: N/A
Study type: Interventional

In France, according to the National Cancer Institute, it appears that treatments in radiotherapy centers for cancer will increase from 198,000 in 2015 to 239,000 in 2030: this represents 40,000 additional treatments in 15 years. A meta-analysis on radiotherapy indicated that 10 to 20% of patients had clinically significant levels of anxiety at the beginning of radiotherapy. Indeed, several factors generate this tension, above all the new or unfamiliar environment, the imposing and noisy scanner, the restraints that are difficult to bear or the nudity required for the examination. This anxiety has an impact on performance of the planning CT scan examination, an essential step for the future treatment. The radiotherapy unit of the Centre Hospitalier Departemental de Vendee has put in place resources to reduce anxiety felt during treatment sessions (music therapy, conversational hypnosis, sophrology or aromatherapy). However, nothing has been put in place to reduce the anxiety of patients in the period preceding the planning CT scan. Virtual reality software seems to be a good alternative that requires fewer human resources. The research hypothesis is that patients who have benefited from the virtual reality software will have a lower level of anxiety before the planning CT scan than patients who have not benefited from virtual reality.
