30-Second Takeaway

  • Selective tracheostomy in free-flap reconstruction can halve trach rates without added airway or flap complications.
  • Frailty- and sarcopenia-based indices better flag patients likely to crash on multimodality head and neck therapy.
  • Early viral cfDNA dynamics may individualize induction chemotherapy intensity and post-treatment surveillance.
  • Frozen section offers excellent rule-in value for oral cavity margins but misses some microscopic disease.
  • Noninvasive diagnostics—from AI breath tests to viscoelastic ultrasound—are approaching clinic-ready status.

Sharper selection, risk tools, and biomarkers in contemporary head and neck practice

Selective prophylactic tracheostomy is safe in free-flap oral and oropharyngeal surgery

ORAL ONCOLOGYMar 29, 2026

Among 411 adults undergoing oral or oropharyngeal free-flap reconstruction, a 2018 initiative promoted selective rather than routine prophylactic tracheostomy. Tracheostomy rates dropped from 92.6% to 42.7% without increasing airway compromise or flap failure. After 2018, tracheostomy use clustered in oropharyngeal primaries, advanced nodal disease, and bilateral neck dissections. Longer surgical and anesthetic times and advanced clinical nodes increased tracheostomy odds, while scapula versus radial forearm flaps decreased them. Patients with tracheostomies had longer hospital stays and more postoperative complications, underscoring morbidity from routine tracheostomy.

mHNSRI improves prediction of treatment intolerance in operable HPV-negative HNSCC

ORAL ONCOLOGYMar 30, 2026

An ambispective cohort of 568 patients with operable HPV-negative stage II–IV head and neck cancer was used to develop the modified Head and Neck Surgery Risk Index. Treatment intolerance, including severe toxicity or therapy non-completion, occurred in nearly half of patients. Low cervical paraspinal skeletal muscle index, higher Risk Analysis Index, reduced high-to-low attenuation muscle ratio, and obesity independently predicted intolerance. Sarcopenia and frailty showed synergistic effects, and adding muscle metrics significantly improved discrimination compared with traditional indices. The mHNSRI achieved an AUC of 0.71 in external validation and outperformed RAI, mFI-5, ASA, and Charlson scores.

Early cfEBV DNA clearance guides induction chemotherapy cycles in LA-NPC

BRITISH JOURNAL OF CANCERApr 1, 2026

This study analyzed 1,590 patients with locoregionally advanced nasopharyngeal carcinoma treated with induction chemotherapy plus chemoradiotherapy. After one induction cycle, 45.5% had undetectable cfEBV DNA, which was combined with N-stage and overall stage to create a risk model. The model stratified patients into high- and low-risk groups with the best 5-year progression-free survival discrimination. In matched low-risk patients, three induction cycles improved 5-year progression-free survival versus two cycles without significantly more grade 3–4 toxicity. High-risk patients gained no progression-free survival benefit from additional induction, suggesting a need for alternative systemic strategies.

ctHPV-DNA sequencing offers highly sensitive surveillance in HPV-positive OPSCC

TRANSLATIONAL ONCOLOGYApr 1, 2026

Target-enrichment sequencing for circulating tumor HPV DNA was applied to plasma from 33 HPV-positive OPSCC patients and 30 non-cancer controls. Baseline ctHPV-DNA was detected in all cancer patients and absent in all controls using robust statistical cutoffs. Post-treatment plasma from patients who remained disease-free stayed ctHPV-DNA negative during up to 24 months’ follow-up. All patients with recurrent disease had ctHPV-DNA detected, sometimes up to a year before clinical diagnosis. Patients with suspected residual neck disease but only necrotic metastasis remained ctHPV-DNA negative, helping distinguish necrosis from viable tumor.

  • Routine prophylactic tracheostomy is increasingly hard to justify when structured selection criteria are applied.
  • Quantifying sarcopenia and frailty outperforms traditional scores for predicting treatment intolerance in HPV-negative head and neck cancer.
  • Viral cfDNA assays (EBV, HPV) are maturing into real-time tools for tailoring therapy and surveillance.
