AI Article Synopsis
Article Abstract
Introduction: Detecting volatile organic compounds in exhaled breath enables the diagnosis of cancer. We investigated whether a handheld version of an electronic nose is able to discriminate between patients with head and neck squamous cell cancer (HNSCC) and healthy controls.
Methods: Ninety-one patients with HNSCC and 72 controls exhaled through an e-nose. An artificial neural network based model was built to separate between HNSCC patients and healthy controls. Additionally, three models were created for separating between the oral, oropharyngeal, and glottic subsites respectively, and healthy controls.
Results: The results showed a diagnostic accuracy of 72% at a sensitivity of 79%, specificity of 63%, and area under the curve (AUC) of 0.75. Results for the subsites showed an AUC of 0.85, 0.82, and 0.83 respectively for oral, oropharyngeal, and glottic HNSCC.
Conclusion: This feasibility study showed that this portable noninvasive diagnostic tool can differentiate between HNSCC patients and healthy controls.

Purpose: Radiotherapy (RT)/cetuximab (C) demonstrated superiority over RT alone for locally advanced squamous head and neck cancer. We tested this in completely resected, intermediate-risk cancer.
Methods: Patients had squamous cell carcinoma of the head and neck (SCCHN) of the oral cavity, oropharynx, or larynx, with one or more risk factors warranting postoperative RT.
Age, Sex, and Anatomical Location Patterns in Cutaneous Pyogenic Granuloma Cases.
JAMA Dermatol
January 2025
Division of Dermatology, Departments of Medicine and Pediatrics, Washington University School of Medicine in St Louis, St Louis, Missouri.
Importance: Cutaneous pyogenic granulomas (PGs) are commonly encountered, benign, vascular tumors, in which epidemiologic factors have been variably reported, in part, due to sample size limitations and a focus on either adult or pediatric patients.
Objective: To assemble a large dataset of pathologically diagnosed PGs across the continuum of age and investigate patterns of PGs by demographic factors, including age, sex, and anatomical location.
Design, Setting, And Participants: This retrospective case series included case reports of patients with pathologically confirmed PGs of cutaneous origin reported between April 1, 2010, to March 31, 2020.
Identification of factors related to functional prognoses in craniopharyngiomas.
J Neurooncol
January 2025
Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, 2-5-1 Shikata-cho, Kita-ku, Okayama, 700-8558, Japan.
Purpose: Craniopharyngiomas are histologically benign tumors, but their proximity to vital neurovascular structures can significantly deteriorate functional prognoses and severely restrict patients' social interaction and activity. We retrospectively identified risk factors related to the functional prognoses in patients with craniopharyngioma treated at our center.
Methods: A retrospective analysis was conducted on 40 patients who underwent surgery for craniopharyngioma and follow-up at our institution between 2003 and 2022.
Impact of smoking status on engagement in remote symptom monitoring after oncologic surgery: Implications for symptom management and readmission rates.
Cancer
February 2025
Department of Psychiatry and Behavioral Sciences, Memorial Sloan Kettering Cancer Center, New York, New York, USA.
Background: Remote symptom monitoring (RSM) is an evidence-based strategy shown to mitigate postoperative morbidity; however, platform engagement is required to benefit from RSM. Patients who report current smoking are at high risk for postoperative complications, but it is unknown whether smoking status influences engagement with RSM, symptom severity, or unanticipated acute care visits.
Methods: This observational case-control study was conducted in patients undergoing ambulatory oncologic surgery at a large cancer center.
Does Cerebrospinal Fluid Leak in Pituitary Surgery Affect Patient Reported Quality of Life?
Laryngoscope
January 2025
Department of Otolaryngology- Head & Neck Surgery, University of Western Ontario, London, Ontario, Canada.
Background: Endoscopic techniques allow for improved visualization and tumor debulking of pituitary adenomas. More thorough tumor resection, however, can be associated with higher rates of CSF leaks. We set out to determine if CSF leaks influenced patient perceived quality of life outcomes.
