Diana D. Shi, MD, of Dana-Farber Cancer Institute and Brigham and Women’s Cancer Center, discusses studies being planned and already underway to test BAY 2402234, a de novo pyrimidine synthesis inhibitor that possibly could be used clinically to target IDH-mutant gliomas and may act as a tumor-selective radiosensitizer (Abstract 167).
Matthew Manning, MD, of Cone Health Cancer Center, discusses findings that showed changes to the way cancer care is delivered may help eliminate racial disparities in survival among patients with early-stage lung and breast cancers. Identifying and addressing obstacles that kept patients from finishing radiation treatments for cancer were associated with improved 5-year survival rates for all patients (Abstract 53).
Daniel F. Hayes, MD, of the University of Michigan Rogel Cancer Center, discusses whether liquid biopsies can provide insight into the challenge of curing metastatic breast and possibly other cancers, how oligometastases are similar to a primary cancer, and why some kinds of local therapy for widespread disease might improve survival and lead to a cure.
Amar U. Kishan, MD, of the University of California, Los Angeles, discusses findings from a meta-analysis of clinical trials in patients with localized prostate cancer. The phase III results suggest that the use of androgen-deprivation therapy (ADT) or prolonged adjuvant ADT with radiotherapy may benefit patients with localized prostate cancer. Further biomarkers are needed to better personalize treatment intensification (Abstract 8).
David A. Palma, MD, PhD, of Ontario’s London Health Sciences Centre, discusses results of the ORATOR2 study, which compared two treatment options that could be de-escalated for patients with HPV-associated oropharyngeal squamous cell carcinoma: a lower-dose radiation approach (6 weeks instead of 7, often with chemotherapy) vs a transoral surgical approach (with low-dose radiation afterward, for 5 weeks) (Abstract LBA2).
Shauna Campbell, DO, of Cleveland Clinic, discusses results from her study that showed hypofractionated intensity-modulated radiation therapy (H-IMRT) in the definitive or postoperative treatment of head and neck cancers using ≥ 50 Gy in 20 fractions appears to be safe and well tolerated with modest toxicity. Dr. Campbell suggests that prospective studies comparing the safety and efficacy of H-IMRT with those of conventionally fractionated IMRT are warranted (Abstract 2313).
