In the United States, the burden of human papillomavirus (HPV)-associated cancers varies by racial/ethnic group. HPV vaccination may provide opportunities for primary prevention of these cancers. Herein, the authors projected changes in HPV-associated cancer burden among racial/ethnic groups under various coverage assumptions with the available first-generation and second-generation HPV vaccines to evaluate changes in racial/ethnic disparities. ⋯ HPV vaccines are expected to reduce the overall burden of HPV-associated cancers for all racial/ethnic groups and to reduce the absolute disparity gap. However, even with the second-generation vaccine, relative disparities will likely still exist and may widen if the underlying causes of these disparities remain unaddressed.

A positron emission tomography (PET) scan after induction chemotherapy before preoperative chemoradiation and surgery for esophageal adenocarcinoma predicts outcomes. Some patients with progression on PET after induction chemotherapy had long-term overall survival (OS) when they were changed to alternative chemotherapy during radiation. ⋯ A PET scan after induction chemotherapy predicts outcomes for locally advanced esophageal adenocarcinoma patients who undergo chemoradiation and surgery. The median PFS is improved, and trends toward improved OS appear possible in PET nonresponders who change chemotherapy during radiation. The fully accrued Cancer and Leukemia Group B 80803 study (NCT01333033) is evaluating this strategy. Cancer 2016;122:2083-90. © 2016 American Cancer Society.
