Alphonse G. Taghian, MD, PhD, of Massachusetts General Hospital, reviews the 10-year follow-up of a dose-escalation trial studying accelerated partial-breast irradiation and discusses the optimal dose, adverse effects, and cosmetic outcomes (Abstract 25).
Juliane Hörner-Rieber, MD, of Heidelberg University Hospital, discusses phase III results of the MINT trial, which showed that conventionally fractionated intensity-modulated radiotherapy with a simultaneous integrated boost was noninferior to three-dimensional conformal radiotherapy followed by a sequential boost for both local control and cosmesis in patients with breast cancer (Abstract 19).
Arjun Sahgal, MD, of the Sunnybrook Health Sciences Centre, discusses results of the first phase III trial to suggest that dose escalation with stereotactic body radiotherapy may be superior to conventional palliative radiotherapy in improving pain outcomes for patients with spinal bone metastases (Abstract LBA2).
Daniel E. Spratt, MD, of the University of Michigan Rogel Cancer Center, discusses a pooled analysis of two phase III trials showing adjuvant androgen-deprivation therapy (ADT) improves biochemical control and reduces distant metastasis when compared with a neoadjuvant approach, with no difference in late gastrointestinal or genitourinary toxicities. The analysis also showed that delaying radiotherapy to deliver neoadjuvant ADT did not benefit most patients (Abstract 32).
Vinai Gondi, MD, of Northwestern Medicine Cancer Center and Northwestern Medicine Proton Center, discusses the preliminary results of an NRG Oncology study of radiotherapy dose intensification using intensity-modulated radiotherapy vs standard-dose radiotherapy with temozolomide in patients with newly diagnosed glioblastoma (Abstract 42).
Youssef Zeidan, MD, PhD, of the American University of Beirut Medical Center, discusses study findings showing that breast-conserving surgery, whole-breast irradiation, and trastuzumab offer effective local tumor control for patients with HER2-positive breast cancer. An additional radiation boost does not seem to further improve outcomes (Abstract 52).
