Article Synopsis
  • Primary meningiomas in the head and neck region are rare, and fine needle aspiration (FNA) can complicate their diagnosis due to their uncommon presentation.* -
  • A case involving a 26-year-old woman revealed a large neck mass that, upon FNA, displayed characteristic cellular features leading to a diagnosis of meningioma with rhabdoid characteristics and loss of the protein BAP1.* -
  • The study underscores the challenges FNA poses for diagnosing extracranial meningiomas and emphasizes the need for additional diagnostic techniques to prevent misdiagnosis.*

Importance: Despite the widespread use of fibula free flap (FFF) surgery for head and neck reconstruction, there are no studies assessing if early weight-bearing (EWB) affects postoperative recovery, and the timing of weight-bearing initiation following FFF surgery varies considerably across institutions. Therefore, it is important to understand the effect of EWB in these patients and whether it could improve postoperative recovery.

Objective: To assess the association of EWB after FFF surgery with donor-site complications, length of stay, and discharge to home status.

Article Synopsis
  • - The study analyzed 145 patients with regionally metastatic cutaneous squamous cell carcinoma (cSCC) who underwent parotidectomy and neck dissection, focusing on their overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS) over three years.
  • - Results showed that the overall survival rate was 74.5%, while the disease-specific survival and disease-free survival rates were 85.5% and 64.8%, respectively; factors like immune status and lymphovascular invasion significantly affected these outcomes.
  • - The findings indicate that patients with immunosuppression and lymphovascular invasion had worse survival outcomes; additionally, those with positive surgical margins or fewer than 18 lymph nodes

Salivary adenoid cystic carcinoma (ACC) is a rare, biologically unique biphasic tumor that consists of malignant myoepithelial and luminal cells. MYB and Notch signaling have been implicated in ACC pathophysiology, but in vivo descriptions of these two programs in human tumors and investigation into their active coordination remain incomplete. We utilize single-cell RNA sequencing to profile human head and neck ACC, including a comparison of primary ACC with a matched local recurrence.

PD-L1 testing guides therapeutic decision-making for head and neck squamous cell carcinoma (HNSCC). We sought to understand whether chemoradiation therapy (CRT) influences the PD-L1 combined positive score (CPS) and other biomarkers of response to immunotherapy. PD-L1 expression was assessed using immunohistochemistry, and bulk RNA sequencing was performed on 146 HNSCC patients (65 primary sites, 50 paired local recurrences, and 31 paired regional recurrences).

Diagnosing salivary gland tumors (SGTs) through fine-needle aspiration (FNA) biopsies is challenging due to the overlapping cytomorphologic features between benign and malignant tumors. The authors developed an innovative, multiplexed cycling technology for the rapid analyses of single cells obtained from FNA that can facilitate the molecular analyses and diagnosis of SGTs. Antibodies against 29 protein markers associated with 7 SGT subtypes were validated and chemically modified via custom linker-bio-orthogonal probes (FAST).

Article Synopsis
  • HPV+HNSCC is a rising HPV-related cancer in the U.S., and traditional diagnostic methods like tissue biopsies and p16 IHC are invasive and vary in sensitivity.* -
  • A study involving 140 subjects found that a noninvasive method using circulating tumor HPV DNA (ctHPVDNA), along with imaging and physical exams, showcased a sensitivity of 95.1% and specificity of 98.6%, outperforming standard methods.* -
  • This noninvasive approach not only improved diagnostic accuracy but also reduced costs by 36-38% and shortened the diagnostic time by 26 days, indicating it could be a more effective alternative in the future.*
