Ultra Hypo-fractionated Adjuvant Whole Breast Radiation Therapy With Simultaneous Integrated Boost for Early-Stage Breast Cancer (H-ASSIST)

This study evaluates the rates of radiation-specific toxicity, quality of life, and oncologic outcomes for early-stage breast cancer and ductal carcinoma in situ treated with 5-fraction whole breast irradiation (WBI) with a simultaneous integrated tumor bed boost (SIB). SIB refers to the technique tumor bed boost given at the same time as standard radiation therapy. The FAST-Forward trial previously showed that a 1-week course of radiotherapy had similar effects to the traditional 3-week course for early-stage breast cancer after surgery. Given these favorable results, a 5-fraction WBI regimen is appealing for many patients who wish to minimize the number of treatment visits while still reducing their risk of recurrence. Generally, tumor bed boosts further decrease the risk of recurrence, but in the setting of 5-fraction WBI, a more traditional sequential boost technique is utilized.

Comparing an Operation to Monitoring, With or Without Endocrine Therapy (COMET) Trial For Low Risk DCIS

This study looks at the risks and benefits of active monitoring (AM) compared to surgery in the setting of a pragmatic prospective randomized trial for low risk DCIS. Our overarching hypothesis is that management of low-risk Ductal Carcinoma in Situ (DCIS) using an AM approach does not yield inferior cancer or quality of life outcomes compared to surgery.

Management of Low-risk (Grade I and II) DCIS

A substantial number of DCIS lesions will never form a health hazard, particularly if it concerns slow-growing low-risk DCIS (grade I and II). This implies that many women might be unnecessarily going through intensive treatment resulting in a decrease in quality of life and an increase in health care costs, without any survival benefit. The LORD (LOw Risk DCIS) study is a non-randomized, international, multicenter, phase III non-inferiority trial, and aims to determine whether screen-detected low-risk DCIS can safely be managed by an active surveillance strategy or that the conventional treatment, being either WLE alone, WLE + RT, or mastectomy, and possibly HT, should remain the standard of care.

Radiotherapy Omission in Low Risk Ductal in Situ Carcinoma Breast

Following breast-conserving surgery (BCS) for localized ductal carcinoma in situ (DCIS) of the breast, whole-breast irradiation (WBRT) is a standard of care, reducing the absolute rate of in-breast recurrences (IBR) by more than 15% at 10 years, from 28% without radiotherapy to 13 % with radiotherapy. Half of the recurrences occurred as invasive disease. Whereas in the comparative trials, WBRT did not impact on overall survival, survival of patients who recurred with invasive cancers was impaired in comparison to patients who did not recur, or to patients with DCIS-only recurrences. Using criteria based on age, tumor size, nuclear grade, and margins status, several trials and cohort studies failed to identify subgroups of patients at low risk, who could be safely spared the need for WBRT. The Radiation Therapy Oncology Group (RTOG) DCIS trial included patients treated with BCS for low- or intermediate grade DCIS revealed by unifocal microcalcifications, size ≤25 mm, margins ≥3 mm, and no residual microcalcifications after surgery. The 5-year rates of IBR were 3.5 % without radiotherapy, versus 0.4 % with radiotherapy, and 6.7 % and 0.9 % at 7 years, respectively (p \<0.001). Sixty percent of the patients received tamoxifen in both groups. Several studies showed that the same molecular classes were identified in DCIS as in invasive cancers. Studies suggested that low proliferation, hormone receptors expression, and lack of ERBB2 amplification were associated with a low risk of IBR in patients not receiving radiotherapy. A combined signature was tested in the Eastern Cooperative Oncology Group (ECOG) trial, showing a 10% IBR rate at ten years in patients with a low-risk. Identifying very low-risk DCIS, using biological markers in addition to the clinical and histological markers of low-risk DCIS, could help to select patients who could be safely avoided WBRT following BCS. It would avoid over-treatment in these women and could decrease the cost of management.

A Prospective CohorT Study of HandX - Assisted ENdoscopic MAstectomy: Feasibility and Safety (ATHENA I Study)

This study aims to learn whether a handheld robotic device, called the HandX, can help surgeons safely perform a minimally invasive nipple-sparing mastectomy. This type of mastectomy uses a small incision at the side of the breast to remove breast tissue while keeping the skin and nipple in place. The goal is to lower scarring, improve comfort, and support good cosmetic results after surgery. Participants in this study will already be planning to have a therapeutic or preventive mastectomy with immediate implant-based reconstruction. All surgeries are done at Mediterraneo Hospital in Greece. During the operation, surgeons use the HandX device to assist with the endoscopic dissection. Researchers will collect information about how long the surgery takes, whether the planned approach can be completed without switching to open surgery, and whether any surgical complications occur. They will also check healing, infection, and implant-related problems for up to 365 days after surgery. Participants will complete the BREAST-Q questionnaire before surgery and at several times after surgery to share their views on comfort, well-being, and cosmetic outcomes. About 15 participants will take part. The results will help researchers understand whether this approach is practical and safe, and whether it should be studied further in a larger trial.

Real-Time MRI-Guided 3-Fraction Accelerated Partial Breast Irradiation in Early Breast Cancer

This trial will investigate a novel 3-fraction radiation regimen for participants undergoing breast-conserving therapy (BCT) for early breast cancer that will: 1) significantly reduce the duration of treatment and can be completed in one-week (5 working days) and 2) MRI-guided radiotherapy (MRIdian) would limit the volume of normal tissue radiated and therefore resultant toxicity. The hypothesis is that 3-fraction radiation therapy can be delivered safely without compromising the therapeutic ratio. Participants can expect to be on study for follow up up to 5 years.

Delayed Selective Sentinel Node Biopsy for Patients Undergoing Mastectomy for DCIS

In the case of a patient undergoing total mastectomy for intraductal carcinoma (DCIS), the sentinel lymph node is not excised during the primary surgery but only marked for identification. If the final histological examination confirms invasive cancer, delayed surgery is performed to remove the sentinel lymph node that was marked during the initial surgery. primary endpoint : The success rate of identifying the sentinel lymph node that was marked during the primary surgery in cases where the final histological examination confirms invasive cancer is evaluated. addendum) The previously documented Breast-Conserving Surgery has been corrected to reflect the accurate procedure of Total Mastectomy.

Delayed Sentinel Lymph Node Biopsy in Ductal Cancer in Situ

The trial aims to investigate the use of superparamagnetic iron oxide (SPIO) nanoparticles as a tracer for delayed sentinel lymph node dissection (d-SLND) in patients where upfront axillary surgery (SLND) is oncologically deemed unnecessary and should be avoided. This includes but is not limited to patients with a preoperative diagnosis of ductal cancer in situ of the breast (DCIS), an unclear BIRADS 4-5 planned for diagnostic excision or women planned for risk reducing mastectomy. SPIO is injected in the primary operation, and should final specimen pathology demonstrate invasive breast cancer, only then is an operation in the axilla (d-SLND) performed.
