Abstract: Hypofractionated radiotherapy (RT) in the setting of early invasive breast cancer has been shown to have similar local control rates and cosmetic outcomes as conventionally fractionated RT. This study compares ipsilateral recurrence rates between hypofractionated and conventional RT, with and without a boost. The effect of hypofractionated RT and chest wall separation (CWS) on cosmetic outcome was also assessed. All patients with ductal carcinoma in situ (DCIS) treated between 1998 and 2012 across two sites of a single cancer institution were retrospectively studied. Patients were analysed according to those receiving conventional RT (≤2 Gy per fraction) and those receiving hypofractionated RT (>2 Gy per fraction), as well as the presence or absence of a tumour bed boost. Data were collected through electronic medical records and local cancer registry. Cosmetic outcome was scored by physicians on a four-point scale during clinical follow-up appointments. One hundred and ninety-seven patients were treated for DCIS during the study period. One hundred and forty-one were treated with conventional RT, and 56 with hypofractionated RT. After a median follow up of 4.4 years, there were 12 ipsilateral recurrences, of which seven were invasive disease and five DCIS. Ten recurrences occurred in patients who received conventional RT (7.1% recurrence rate) and two in those who received hypofractionated RT (3.6% recurrence rate) (P = 0.48). Cosmetic outcomes were not significantly different between conventional and hypofractionated RT (P = 0.06). Hypofractionation represents a suitable alternative for treating DCIS in the absence of randomised data.

Abstract: This study aims to investigate the mediating role of management control system (MCS) characteristics in the relationship between state type, reflected through societal institutions (SIs), and two sets of management accounting techniques (MATs), namely, performance measurement techniques (PMTs) and cost measurement techniques (CMTs). Structural equation modeling was used to analyze data from a cross-sectional survey of 136 firms in the United Arab Emirates (UAE). The findings show a direct positive impact of state-type construct on MCS characteristics, and that MCS characteristics partially mediate the reported significant relationships between state type and the use of PMTs. While the findings show a similar positive relationship between state type and CMTs, MCS characteristics do not mediate this relationship. Although these results are affected by limitations associated with the survey method used, they are useful in explaining the necessary conditions supporting the use of MATs in general and performance measurement techniques in particular. The study uses a cross-section of companies in the UAE, an attractive global investment destination, as its s le. The results can help investors better understand the choice of MATs in the UAE and its relation to MCS characteristics. This study contributes to management accounting literature by determining the mediating role of MCS characteristics on the relationship between state type and the choice of two sets of MATs, whereas existing literature assumes a direct relation between the two.
