EP-2047: Surface guided radiotherapy increases setup accuracy for locoregional breast cancer patients

Modulated Radiotherapy for Breast Cancer: Locoregional Outcomes

Breast cancer is the commonest cancer among females worldwide as well as in India, accounting for 27% of all cancer and 21% of cancer related deaths in India [1]. Over last few decades, better understanding of disease biology, early detection and advances in treatment techniques have led to improved outcomes. Newer approaches are being studied to improve treatment outcome with decreased treatme...

Surface Imaging for Patient Setup and Monitoring for Breast Radiotherapy

Image-guided prostate radiotherapy: analysis of inter- fractional setup errors

Introduction: The accuracy of the patient setup and tumor location are major factors that determine the efficacy of radiotherapy treatment planning. In the prostate radiotherapy, reproducibility of the prostate location for each treatment fraction is problematic owing to varying filling of the rectum and bladder. According to this, the aim of this study was to measure the inte...

Trastuzumab improves locoregional control in HER2-positive breast cancer patients following adjuvant radiotherapy

The benefit of adjuvant trastuzumab in disease-free and overall survival for human epidermal receptor 2-positive (HER2+) breast cancer patients is well established. However, the effect of trastuzumab on locoregional control remains unclear, particularly in patients treated with adjuvant radiotherapy (RT). In this study, we investigated the locoregional benefit of trastuzumab in patients with HE...

Comparison of setup accuracy of three different image assessment methods for tangential breast radiotherapy

INTRODUCTION To compare the differences in setup errors measured with electronic portal image (EPI) and cone-beam computed tomography (CBCT) in patients undergoing tangential breast radiotherapy (RT). Relationship between setup errors, body mass index (BMI) and breast size was assessed. METHODS Twenty-five patients undergoing postoperative RT to the breast were consented for this study. Weekl...
