View clinical trials related to Ductal Carcinoma In Situ.
Filter by:Ductal carcinoma in situ (DCIS) accounts for approximately 20% of newly diagnosed breast cancer cases. Of these women, 20% require radical management in the form of mastectomy because of the extent of the lesions, which most often manifest as diffuse microcalcifications. This mutilating surgical management contrasts with the excellent prognosis of this pathology and considerably alters the quality of life of patients. Neoadjuvant hormone therapy has shown its efficacy in hormone-dependent infiltrating ductal carcinomas and offers the possibility of conservative surgery after hormone therapy. Adjuvant hormone therapy with Tamoxifen or anti-aromatase drugs has shown its efficacy in the prevention of homo or contralateral recurrence. The HORNEO 01 trial fits perfectly in the current context of surgical de-escalation of ductal carcinomas in situ. The objective of the study is to evaluate the impact of neoadjuvant hormone therapy on the surgical management of extensive DCIS.
Analysis of women's medical records to understand the impact of previous changes to breast cancer screening (increase from one to two clinicians examining each woman's mammograms, and what proportion of women they recall for further tests)
The purpose of this trial is to assess the efficacy of the Xoft Axxent eBx System when used for single-fraction IORT in early stage breast cancer. A comparison will be made to the current standard of care, whole breast irradiation (WBI), in women with early stage breast cancer.
The investigators have developed a novel ultrasound-guided nerve block indicated primarily for breast cancer surgery that mimic a thoracic paravertebral block (TPVB) - hitherto the internationally accepted regional anesthesia golden standard for anesthesia of the hemithorax - but hypothetically without the risks of adverse events associated with the TPVB (i.e. pneumothorax, risk of bleeding in the thoracic paravertebral space, random and unmanageable epidural spread etc.). The investigators have already tested the anatomical- and block execution hypothesis in a randomized cadaveric study, and the investigators now have anatomical proof of concept for the functionality of the block technique. The investigators have also conducted a small clinical pilot study with very promising results. The investigators wish to conduct a randomized, placebo controlled and double-blind study, comparing the effect of the ultrasound-guided multiple-injection costotransverse block (MICB) vs. placebo. The aim with this study is to investigate the efficacy of the MICB vs. placebo in patients undergoing unilateral mastectomy and primary reconstructive surgery due to breast cancer or ductal carcinoma in situ. The hypothesis is, that the unilateral MICB will significantly reduce the opioid consumption during the first 24 postoperative hours and significantly reduce the Numerical Rating Scale pain score (0-10) and opioid related side effects.
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 research study is to evaluate a decision support tool for patients diagnosed with ductal carcinoma in situ (DCIS).
Partial breast irradiation is typically performed after surgical removal of the tumor. Partial breast irradiation allows for focused radiation to the area from which the cancer was removed, sparing breast tissue from the potential bad effects of radiation compared to radiating the whole breast, which was the standard of care for many years. This study is evaluating the use of partial breast irradiation with NIBB performed before surgery instead of after surgery.This should allow researchers to target the cancer even more accurately and result in less normal breast tissue receiving radiation which may cause less side effects and/or a better cosmetic outcome. In this study partial breast treatment will be given with NIBB in 5 treatments over about 1 week. Surgical removal of the tumor will then be performed between 4-12 weeks following radiation treatment. Researchers believe that participant's risk of complications from surgery will not be higher after getting these radiation treatments than it would have been if participants had surgery first, but that is one of the things researchers are studying.
The proposed study will be a pilot randomized controlled trial comparing treatment as usual (TAU) to treatment as usual plus a brief Acceptance and Commitment Therapy (ACT) intervention (TAU + ACT) with mastectomy and lumpectomy patients identified as at-risk for developing persistent post-operative pain. The ACT intervention is a single individual therapy session scheduled two weeks following surgery. Potential participants will be recruited from the University of Iowa Breast Cancer Clinic. A sample size of n = 30 for each arm will be recruited. An attrition rate of 20% is anticipated so the total N to be recruited for the study is 72 participants. Study measures will consist of self-report questionnaires and medical record data. Data will be collected prior to surgery, one-week after surgery, and 3 months after surgery.
This study aims to discover more about radiation techniques for people treated for left-sided breast cancer that minimizes exposure to the heart, as noted by mean heart dose.
The goal of this study is to examine the role of Intraoperative Radiotherapy (IORT) in Ductal Carcinoma In-Situ (DCIS) and to improve the understanding of the clinical, radiographic, and patient-related impact of adopting IORT.
