One Week Versus Three Week in Adjuvant Radiotherapy in Breast Cancer

Background:Moderate three week hypofractionated adjuvant radiotherapy schedule is a standard care in breast cancers. A five day schedule has been demonstrated to be iso-toxic as a standard three week schedule. Recently studies have also demonstrated the safety and feasibility of simultaneous integrated boost in this setting. This randomized trial will investigate if a one-week course of hypofractionated breast radiotherapy is non-inferior to a three week course. Aim: To determine if one-week schedule of adjuvant radiotherapy in breast cancer is non-inferior to a three week schedule. Primary Objective: Locoregional Recurrence Rate (LRR) (Cumulative proportion of patients with locoregional recurrence) at 5 years Secondary Objective: Overall survival (OS) (Time from randomization to death) Invasive Disease-free survival (iDFS) (Time from randomization to any invasive disease recurrence, death due to any cause or second invasive malignancy) Late adverse events (AE) Quality of Life (QoL) Hypothesis: 1 week schedule will be non-inferior to a three week schedule for Locoregional Recurrence Rate 1 week schedule will be non-inferior to a three week schedule for OS 1 week schedule will be not result in worse late adverse events as compared to 3 week schedule Proportion of patients decrease in quality of life will not differ between the two arms at 12 months Design: Open-label, parallel group, two arm, randomised, phase III, non-inferiority trial. Population: Patients with breast cancer who need adjuvant radiotherapy after breast conservation or mastectomy. Intervention: Patients will be randomized to 15 days or 5 days of radiotherapy to the whole breast or chest wall or reconstructed breast. Nodal radiation will be delivered as indicated. A simultaneous integrated boost (SIB) will be delivered to patients who need a tumor bed boost after breast cancer. The following dose schedules will be tested: Control Group: 40 Gy in 15 fractions over 3 weeks (with SIB of 8 Gy)* Test Group: 26 Gy in 5 fractions over 1 week (with SIB of 6 Gy).* * Use of Sequential Boost is allowed in both arms if prespecified by the institution. If used dose is 12 Gy in 4 fractions in 1 week in both arms. Outcomes and measures: LRR : Cumulative proportion of patients with ipsilateral Locoregional Recurrence after treatment at 5 years . OS: Time from randomization to the time of death due to any cause. Cumulative proportion reported at 5 years. iDFS: Time from randomization to any disease recurrence, death due to any cause or second primary invasive cancer.Cumulative proportion reported at 5 years. AE: Proportion of patients with late Grade 2 or more AE as defined by the CTCAE 5 criteria QoL: Proportion of patients with a worse summary score in the EORTC QLQ C30 at 12 months post-treatment as compared to the baseline score.

Simulating Outcomes From Breast Conserving Surgery Using 3D Surface Imaging

Most women with breast cancer are able to have an operation to remove the cancer while preserving the breast (breast conserving therapy, BCT). Whilst cancer control is the most important goal, appearance of the breast after surgery has been shown to affect the quality of a woman's life after treatment. This is even more relevant now that most women are surviving breast cancer. Before surgery, women are prepared for how they will look afterwards by having a discussion with the Surgeon or Breast Care Nurse. Sometimes women are shown two dimensional (2D) (standard) photographs of other women who had a similar operation. Patients have stated that viewing photographs of other patients does not prepare them adequately for their own experience of surgery. Three dimensional (3D) digital photography is currently being used to predict the appearance of the breasts after enlargement surgery using specialist software. The investigators intend to use a similar system to simulate a patient's appearance after BCT for cancer. The investigators believe that this will lead women to feel better prepared for their surgery, reduce stress, and lead to greater satisfaction with their breast after treatment. This study invites women undergoing BCT to be assigned at random to one of three groups receiving standard care (discussion), a 2D photograph, or the 3D simulation before their operation. The investigators will find out whether women feel better prepared for surgery and are more satisfied with their outcome if they are shown a simulated image of how their own breasts are likely to look. By taking 3D photographs of all study patients before and after surgery, a more accurate way to predict appearance after surgery will be developed for future patients.
