Morphine treatment restricts response to immunotherapy in oral squamous cell carcinoma.

Background: Immune checkpoint inhibitors (ICIs) are becoming the standard of care for recurrent and metastatic cancer. Opioids, the primary treatment for cancer-related pain, are immunosuppressive raising concerns about their potential to interfere with the efficacy of ICIs. We hypothesize that exogenous opioids given for analgesia suppress antitumor immunity via T cell-mediated mu opioid receptor 1 (OPRM1) signaling.

Integrating priorities at the intersection of cancer and neuroscience.

Cancer neuroscience is a rapidly growing multidisciplinary field that conceptualizes tumors as tissues fully integrated into the nervous system. Recognizing the complexity and challenges in this field is of fundamental importance to achieving the goal of translational impact for cancer patients. Our commentary highlights key scientific priorities, optimal training settings, and roadblocks to translating scientific findings to the clinic in this emerging field, aiming to formulate a transformative and cohesive path forward.

Quality of Life Outcomes for Parotid Malignancies.

Background: This study describes patient-reported outcome measures (PROMs) and associated factors in patients who underwent surgery for malignant parotid tumors (MPT).

Methods: This is a retrospective study of all surgically treated MPT patients in a multidisciplinary head and neck cancer (HNC) survivorship clinic (2017-2023). PROMs included University of Washington Quality of Life Questionnaire (UW-QOL), Eating Assessment Tool (EAT-10), Patient Health Questionnaire (PHQ-8), Generalized Anxiety Disorder (GAD-7), Neck Disability Index (NDI), and Insomnia Severity Index.

Next Directions in the Neuroscience of Cancers Arising outside the CNS.

The field of cancer neuroscience has begun to define the contributions of nerves to cancer initiation and progression; here, we highlight the future directions of basic and translational cancer neuroscience for malignancies arising outside of the central nervous system.

Pretreatment pain predicts perineural invasion in patients with head and neck squamous cell carcinoma.

Objectives: Perineural invasion (PNI) in head and neck cancer (HNC) is a distinct pathological feature used to indicate aggressive tumor behavior and drive treatment strategies. Our study examined the prevalence and predictors of PNI in HNC patients stratified by tumor site.

Study Design And Methods: A retrospective analysis of head and neck squamous cell carcinoma (HNSCC) patients who underwent surgical resection at the University of Pittsburgh Medical Center between 2015 and 2018 was performed.
