Guest Editor Ryan T. Fitzgerald

Human papillomavirus (HPV) is now recognized as the primary causative factor in a subgroup of epidemiologically and clinically distinct cancers of the head and neck, oropharyngeal squamous cell carcinoma (OPSCC).1,2 The rising incidence of OPSCC relative to squamous cell cancers elsewhere within the mucosal spaces … more »

Chemoradiotherapy (CRT) as definitive treatment has become a standard management option for many patients with head-and-neck squamous cell carcinoma (HNSCC), in order to improve the patient’s quality of life via organ preservation. However, the disease control achieved with CRT remains heterogeneous because the treatment responses and clinical outcomes … more »

Differences in Imaging Characteristics of HPV-Positive and HPV-Negative Oropharyngeal Cancers: A Blinded Matched-Pair Analysis

Lawrence Ginsberg

Lawrence E. Ginsberg

The topic was chosen because we are witnessing a tsunami of HPV-associated oropharyngeal cancers. As smoking-related head-and-neck malignancies wane (along with lung cancer), oropharyngeal cancer is on the upswing.

Earlier work in AJNR, also authored by my colleague Dr. Sarah Cantrell, focused on radiologic differences between HPV-positive and … more »

Improving Imaging Diagnosis of Persistent Nodal Metastases after Definitive Therapy for Oropharyngeal Carcinoma: Specific Signs for CT and Best Performance of Combined Criteria

Jackson Hamilton

With human papillomavirus infection reaching epidemic proportions, oropharyngeal cancers are expected to increase in a younger population than that historically afflicted with head and neck cancer. Because these tumors are most often treated nonsurgically, there is always a debate as to whether nodal dissection for posttreatment residual … more »
