Post-treatment 18F-fludeoxyglocuse-positron emission tomography in human papillomavirus-associated oropharyngeal cancer.

Background: Human papillomavirus association has changed the landscape of treatment for oropharyngeal squamous cell carcinoma; it remains to be seen whether current post-treatment surveillance schedules are effective.

Objective: Evaluate whether post-treatment surveillance of oropharyngeal cancer through FDG-PET imaging is modified by human papillomavirus association.

Methods: A prospective cohort analysis of retrospective data was conducted for patients undergoing treatment of oropharyngeal cancer between 2016 and 2018.

Nipple Reconstruction: A Regenerative Medicine Approach Using 3D-Printed Tissue Scaffolds.

This work provides a comprehensive overview and critique of nipple reconstruction techniques to date. It then explores different tissue engineering concepts and how these may improve clinical outcomes for patients undergoing nipple reconstruction. A novel technique is proposed, whereby a three-dimensional-printed tissue-engineered construct is used as an autologous graft to assist nipple reconstruction.
