Background: HPV infection is implicated in approximately half of global penile squamous cell carcinoma (PSCC) cases. Previous studies on HPV DNA and p16INK4a status in PSCC have yielded inconclusive prognostic findings. This meta-analysis aims to elucidate the prognostic role of HPV in PSCC by pooling data on disease-free survival (DFS), disease-specific survival (DSS), and overall survival (OS).

Soft tissue sarcomas (STS) are radioresistant with a low α/β, which may have a biologic benefit with hypofractionation. For unresectable STS, the dose escalation required to achieve durable control is often limited by long-term toxicity risk. We sought to compare an isotoxic approach utilizing hypofractionated accelerated radiation dose-painting (HARD) versus standard fractionated radiation therapy (SFT) in patients with unresected STS.
