Objectives
Optimal contouring of fibula free flaps (FFF) for mandibulectomy often requires osteotomies. This study aimed to define criteria for initial gap width by evaluating whether postoperative gap size and other factors influence long-term osseous union on CBCT, and to identify key determinants of bone healing.
Methods
This retrospective study included 75 patients who underwent segmental mandibulectomy with FFF reconstruction from 2017 to 2024. Initial osteotomy gaps were measured at four points on postoperative CBCT scans. Osseous union was assessed using a callus scale. Demographic, anatomical, and surgical variables—including 3D-assisted planning, fibula morphology, osteotomy location, systemic comorbidities, and segment number —were analyzed using uni- and multivariate regression models.
Results
A total of 202 osteotomy sites were evaluated. The mean initial gap was 1.68 ± 0.97 mm, and gap size did not significantly predict long-term union. Complete union occurred in 50.0% of sites, partial union in 36.6%, and nonunion in 13.4%. Fibula–fibula interfaces showed significantly better healing than fibula–mandible interfaces (p < 0.001). Symphyseal osteotomies demonstrated superior union compared with body and angle regions. Systemic vascular comorbidities were strong negative predictors of union, whereas reconstructions using more than two segments showed improved outcomes (p < 0.001). Alcohol consumption negatively affected both initial gap formation and union.
Conclusions
Long-term osseous union after FFF reconstruction is influenced mainly by systemic vascular health, osteotomy location, interface type, and fibula morphology rather than initial gap width.

Intro
Population-based studies predominantly focused on carcinoma of the parotid gland (CPG) are rare. The study aims were to analyze the incidence of CPG and to assess treatment outcomes in relation to histopathology, preoperative diagnosis and adjuvant radiotherapy.
Methods
A retrospective analysis was conducted on data from the Swedish Head and Neck Cancer Register (SweHNCR), including 1,018 patients diagnosed with CPG between 2008 and 2019.
Results
The age-adjusted incidence remained stable with a mean of 0.9 (range 0.65–1.08) cases per 100,000 person-years (ASR-Europe). Curative treatment was administered to 90 % of the patients, with a recurrence rate of 9 % within 3 years. The highest recurrence rates were observed in patients with salivary duct carcinoma and adenocarcinoma, while patients with acinic cell and mucoepidermoid carcinomas had lower recurrence rates. For stage I–II tumors, the 5-year relative survival was unaffected by whether the malignant diagnosis was known preoperatively. Male sex, increasing age, stage III–IV disease, and a World Health Organization/ Eastern Cooperative Oncology Group (WHO/ECOG) performance status 2–4 was independently associated with increased overall mortality risk, whereas the timing of adjuvant radiotherapy was not.
Conclusion
This study contributes to establishing the incidence and treatment outcomes of CPG in Sweden and highlights the diverse histopathological diagnoses of these tumors. Notably, unknown malignancy at the time of surgery did not impact survival in early-stage disease, and the timing of postoperative radiotherapy was not associated with overall survival.

Background/Objectives: Inflammation and immune evasion are linked to tumor progression. This cancer-related inflammatory response is reflected by a biomarker named the systemic inflammatory response (SIRI). SIRI is calculated by multiplying the peripheral blood neutrophil and monocyte counts and dividing by the lymphocyte count is a biomarker that has shown prognostic capacity in squamous cell head and neck cancer. We sought to perform a meta-analysis of SIRI data for head and neck cancer. Methods: A meta-analysis using a mixed-effects model was performed to estimate the overall effect size of prognostic capacity. The primary outcomes of interest were overall survival and progression-free survival, with effect sizes measured as log hazard ratios (HR). Results: Ten studies reporting data on overall survival revealed a pooled HR of 2.4 (p < 0.0001). This indicates higher SIRI patients are at greater risk of mortality relative to lower SIRI patients. Additionally, 3 studies reported metrics on progression-free survival, with a pooled HR of 2.32 (1.72, 3.13) (p < 0.0001). Minimal heterogeneity was observed for progression-free survival (I2 = 0%, p< 0.74). Conclusions: High SIRI portends worse overall survival. Since SIRI correlates to immune function and demonstrated minimal heterogeneity, these factors are among those most likely to be impacted by altered SIRI parameters.

Purpose
Efficient resource allocation in surgery requires thorough economic evaluation that reflects the true costs of a procedure, with micro-costing being a primary method. Existing economic studies on microvascular jaw reconstruction of the jaw often exclude or estimate key cost-drivers. The aim of this study was to estimate the direct financial costs and cost-drivers associated with surgical reconstruction of the jaw from the perspective of the healthcare provider.
Methods
A retrospective micro-costing study from the perspective of the healthcare provider was performed on 100 patients who underwent mandibular or maxillary free flap reconstruction. Direct financial costs of activities (in USD) from admission to discharge were examined, and classified into operative and perioperative admission periods.
Results
The mean cost for the entire admission was $36,415.95 ± 14,246.56 comprising 57.7% from the operative period and 42.3% from the perioperative admission period. Ward staffing and consumables (35.7%), prostheses (25.0%), and operating room staffing (21.0%) were the largest cost contributors. In adjusted analyses, higher costs were associated with vasculopathy (+$9142.02, p = 0.044), ASA IV ($19,495.93, p = 0.023), tracheostomy (+$10,445.81, p = 0.012), return to the operating room (+$19,920.22, p = 0.005), and return to the intensive care unit (+$25,316.26, p = 0.014).
Conclusion
Jaw reconstruction is associated with considerable direct financial costs to the healthcare provider with complications requiring return to the operating room and/or return to the intensive care unit the critical key cost-drivers. These insights will support future health technology assessments focused on jaw reconstruction to assist decision-makers in implementing or reimbursing these procedures.

Worst pattern of invasion (WPOI) has been evaluated in many single-institute cohorts. Our goal was to perform a large multicentre evaluation of WPOI as a prognostic marker in oral squamous cell carcinoma (OSCC). Retrospective pathology data was collated from 14 institutions and compared with clinical outcome in 1374 OSCC patients with upfront curative resection. Most cases were of oral tongue (n = 645, 47%); T2 (33%) and N0 (59%). WPOI 1–3 frequency was 29.4%, WPOI 4 47% and WPOI 5 22%. On univariable analysis, the 3-year disease free survival (DFS) was 54.2% for WPOI 5 vs. 69.7% for WPOI 1–4 (p < 0.001). The locoregional control (LRC) was 68.9% vs 79.2% (p = 0.001), and overall survival (OS) 68.4% vs 83.8% (p < 0.001). On multivariable Cox-regression in the entire cohort, WPOI 4 or 5 was strongly correlated with other known poor prognostic factors and not an independent predictor of OS (HR 1.10, 95% CI 0.92–1.52), LRC or DFS. However, in early-stage (pT1-2 N0) patients treated with surgery alone without adjuvant radiotherapy, WPOI 5 was a robust independent predictor of DFS (HR 4.36, 95% CI 1.54–12.32, p = 0.006), OS (HR 3.69, 95% CI 1.23–11.1, p = 0.020) and LRC (HR 3.52, 95% CI 2.13–5.82, p <0.001) after applying inverse probability weighting to correct for selection bias. Furthermore, in the entire cohort of early-stage patients, interaction modeling showed that adjuvant radiotherapy significantly reduces the risk for both DFS and LRC for those with WPOI-5 (Interaction p = 0.002). Therefore, it may act as a predictive biomarker for the benefit of adjuvant radiotherapy. The prognostic and predictive role of WPOI-5 should be validated in prospective trials.

Background
The management of head and neck cancer relies on multidisciplinary expertise; however, access to tumor boards remains variable. Large language models (LLMs) may support guideline-based decision-making, although performance in complex oncologic scenarios is not well defined.
Methods
Fourteen synthetic cases based on real tumor board encounters were evaluated. Five blinded comparator arms produced recommendations: a human expert, Non-RAG-GPT-4, Non-RAG-GPT-5, RAG-GPT-4, and RAG-GPT-5. Eight head and neck oncologic surgeons scored each recommendation for appropriateness, clarity, specificity, and feasibility using 5-point Likert scales. Paired permutation testing and inter-rater reliability were assessed.
Results
LLM outputs showed close alignment with expert recommendations. RAG-based models achieved the highest mean scores across domains, with some statistically significant differences versus the expert comparator in appropriateness and clarity; however, absolute differences were modest. Inter-rater reliability was strong (ICC 0.73–0.87).
Conclusions
Advanced LLMs can generate guideline-concordant management recommendations in simulated head and neck cancer cases, supporting potential utility for decision support and education; prospective validation and expert oversight remain essential.
