NCT ID: NCT03677427 Recruiting - Breast Cancer Clinical Trials

Comparing 5 and 15 Fractions for Whole Breast Irradiation After Breast Conserving Surgery

Start date: October 16, 2017
Phase: N/A
Study type: Interventional

Adjuvant radiotherapy after breast-conserving surgery for breast cancer reduces the risk of locoregional relapse and ensures better overall survival. In recent years it has been found that hypofractionation in which the number of radiation sessions is reduced with a higher dose per session offers advantages for breast irradiation. Randomized studies showed that moderate hypofraction regimens in 15 or 16 fractions have the same effect in tumor control and toxicity, although the total dose is lower than the traditional 50 Gy in 25 fractions. In a randomized study from the United Kingdom (START-B trial) even a better disease-free survival was seen with 15 sessions than with 25 sessions and the long-term side effects were also less with the short schedule. This project proposes a clinical trial with an accelerated radiotherapy schedule in 5 sessions. It is expected that the accelerated schedule of 5 sessions over 12 days will have a number of radiobiological benefits: since a higher dose per session is given over a shorter period of time, it is expected that tumor control and survival will be higher. By reducing the total treatment time, the total dose is reduced, which may result in fewer radiation-related side effects and thus improve the quality of life. Apart from these radiobiological benefits, the shorter radiotherapy program reduces the number of treatment days from 15 to 5. This is not only more comfortable for the patients, but also increases the treatment capacity of the radiotherapy department. This opens up a possibility for the use of more complex techniques with fewer side effects such as radiation in the prone position. This project includes a randomized study comparing the accelerated schedule in 5 sessions with a hypofraction schedule of 15 sessions in patients who are irradiated on the entire breast after breast-saving surgery. The primary endpoint is chest retraction (loss of volume) 2 years after radiotherapy.

Diagnostic Accuracy of Dermal Thickness in Lymphedema

Start date: September 28, 2018
Study type: Observational

Ultrasound is an easily feasible noninvasive technique which is widely used in rehabilitation settings. Measurement of dermal thickness via ultrasound can be less time consuming than volume measurements with water displacement and circumference measurements. Measurement of subcutaneous tissue thickness were used for both assessment and treatment outcome. Recently reliability of ultrasound examination of thickness of the skin and subcutaneous tissue were studied by Han et al. However, diagnostic accuracy of this method has not been studied before. Early identification of breast cancer related lymphedema to start treatment earlier is critical. Consequently, reliability and diagnostic accuracy of the assessment techniques of lymphedema is crucial to evaluate both severity at the time of diagnosis, and later effectiveness of treatment. The aim of this study was to establish diagnostic accuracy of between side differences of ultrasonographic dermal thickness measurements in breast cancer related arm lymphedema.

Hypo-Fractionated Radiotherapy in Breast Cancer

Start date: January 2, 2018
Phase: N/A
Study type: Interventional

This is a prospective interventional phase I/II study which will be done at Tata Medical Centre, Kolkata. Total 30 eligible female patients, ≥18 years of age, with locally advance invasive carcinoma of breast, not amenable to curative surgery of metastatic breast cancer, planned for palliative loco regional radiotherapy will be enrolled in the study amongst which patients with left sided breast cancer (at least 10) will be recruited to study the feasibility of voluntary breath hold technique for heart sparing. Once consented, all patients will have regional baseline PET-CT scan of breast and tissue biopsy along with blood sampling done before studying radiotherapy. Planning Ct scan will then be taken, with standard planning CT scan for right breast cancers with implementation voluntary breath hold technique for the left breast disease. All patients will be treated with hypo-fractionated radiotherapy with schedule of 26Gy on 5 Fractions over 1 week with 6Gy simultaneously integrated boost with incorporation of breath hold technique for left breast disease. All patients will be assessed weekly during course of radiotherapy. The toxicity will be assessed using CTCAE version 4 and LENT SOMA toxicity criteria and the impact of the hypo-fractionated breast radiotherapy schedule on quality of life in advanced incurable breast cancer patients using FACT B scores PHQ4 questionnaire will also be assessed during treatment and follow-ups tissue bio0psy will be taken after 2 hours of completion of 1 st and last fraction of radiotherapy and biobanked for future radiobiological tests. Response evaluation will be done clinically and by regional PET CT scan using PERSIST criteria in 3 months after completion of radiotherapy. After completion of treatment, patient will initially be followed up every month for 1 st three months thereby 3 monthly for 2 years and 6 monthly for next 3 years.

Endogenous Mechanisms of Inactivation of the Endothelium Tumor

Start date: January 31, 2018
Study type: Observational

The role of immunity in the development of cancers, and the associated escape mechanisms, have attracted renewed interest since the publication of tests testing immunological checkpoint inhibitors. One of the steps in the probably least studied immunological response is the penetration of immunocompetent cells within the tumor across the vascular barrier. This infiltration is suggested as a prognostic and predictive marker of treatment response, particularly in triple negative HER2 (Human Epidermal Growth Factor Receptor-2) overexpressing breast cancers. The methods of evaluating these infiltrates are complex and have been the subject of recommendations. A better understanding of the mechanisms of infiltration of immunity cells within tumors will certainly help to better understand the impact of cancer treatments and develop new therapeutic strategies. It is this issue of vascular endothelium that Dr. Soncin's team is developing as part of an INCa (Institut National du cancer) project. The egfl7 / VE-statin (vascular endothelial-statin) gene is thought to be involved in transendothelial passage of immune cells from vascular lumen to tumor. Its expression has already been studied in a series of breast cancers. Other markers of endothelial activation are currently being identified. The main objective of this project will be to better understand the behavior of the endothelium in a population of breast cancer where the infiltrate in immune cells is precisely likely to play a leading role. This retrospective cohort of 250 to 300 cases treated with adjuvant and neoadjuvant will be immunologically characterized using the recommendations of Salgado et al. that a multicentric team of pathologists will take ownership. This evaluation will be counter-appraised. Once our cohort is immunologically characterized, our project will focus on better understanding the endothelial mechanisms involved: which cells? immunophenotyping of immunity cells. By which vessels? (measurement of densities in blood and lymphatic vessels, density in HEV). By what mechanisms? Do the actors identified in vitro within the Inca project have an in vivo translation

Dermacell ADM Without Basement Membrane

Start date: September 1, 2018
Phase: N/A
Study type: Interventional

DermACELL acellular dermal matrix (D-ADM) is the trade name of LifeNet Health's acellular dermal matrix (ADM). LifeNet Health will remove the basement membrane from the D-ADM and this product will be compared to FlexHD® Pliable, which does not include a basement membrane in order to demonstrate that D-ADM without a basement membrane is not inferior to FlexHD in the frequency of significant side effects that result from breast implants. This is a post market trial that is comparing two ADM products with a known safety profile. The D-ADM without a basement membrane is being prepared specifically for this UVA evaluation. Removal of the basement membrane by the manufacturer is considered minimal manipulation. D-ADM without a basement membrane will be considered a human cell, tissue, and cellular and tissue-based product (HCT/P) and is eligible for marketing immediately within the US, if desired by LifeNet Health (LNH). Additionally, the applications of the products are indicated. Therefore, the trial is not in support of an Investigational Device Exemption (IDE). Prior to surgery, the registered subject will be randomized to receive the D-ADM without the basement membrane or the comparator, FlexHD Pliable. The surgeon and the patient will be blinded to the product group. The patient will receive the ADM at the time of placement of the tissue expander. After a period of tissue expansion, the patient will have the expander-implant exchange. During this surgery, there will be 3 punch biopsies taken in 3 different locations: native breast tissue, center of the ADM, and the border of the ADM and subject's breast tissue. These specimens will be analyzed to estimate differences in immunologic and inflammatory response for each ADM product. The patient will follow up with the surgeon at 1-3 weeks, 3 months, 6 months, 9 months, and 12 months post implant exchange. At these visits, the surgeon will assess for any adverse events and this information will be collected for research purposes. The patient will be asked to complete the reconstruction module of the Breast-Q at the baseline visit and 6 and 12 months to assess quality of life and patient satisfaction.
