Objectives: The aim of this study was to assess the incidence rate for surgical site infections (SSI), patient- and therapy-related risk factors in UICC stage III and IV oral squamous cell carcinoma patients treated with preoperative radiochemotherapy, ablative surgery and immediate microvascular free flap reconstruction.
Material And Methods: This retrospective analysis included 85 patients with oral squamous cell carcinoma treated by neoadjuvant radiochemotherapy, tumor surgery and immediate free flap reconstruction. Patient-, therapy-related factors and blood parameters were collected for this selective cohort.
Results: The incidence for SSI was 44.7% and for transplant loss 14.1%. Minor BMI changes (p = 0.010), diabetes (p = 0.003), edentulous status (p = 0.006) and cessation of alcohol consumption (0.034) showed to be significant patient-related risk factors. No therapy-related factors were found to be significantly influencing the risk for SSI. Neutrophil counts (p = 0.027) and GGT (p = 0.002) were found to be significantly linked to SSI.
Conclusion: The not so common treatment option for oral squamous cell carcinomas showed no more risk for SSI compared to standard treatment options. Preserving the ability for healthy nutrition has a significant impact on the development of SSI. This applies not only to the presented and particular treatment option.

There are 275,000 new cases of oral cancer (OC) per year, making it the sixth most common cancer in the world. Severe adverse effects, including loss of function, deformity, and systemic toxicity, are familiar with traditional therapies such as radiation, chemotherapy, and surgery; due to their unique properties, nanoparticles (NPs) have emerged as a superior alternative over chemo/radiotherapy and surgery due to their targeting capability, bioavailability, compatibility, and high solubility. Due to their unique properties, metallic NPs have garnered significant attention in OC control.

Background: The current NCCN guidelines advocate for the use of adjuvant radiotherapy (RT) or chemoradiotherapy (CRT) in pT3N0 oral cavity squamous cell carcinoma (OCSCC). Here, we sought to evaluate whether postoperative RT/CRT may confer a survival advantage in pT3N0 patients who lack adverse pathological features.
Methods: A dataset of 852 pT3N0 OCSCC patients treated between 2018 and 2021 was analyzed.

Objective: This study aimed to investigate the role of transmembrane emp24 domain-containing protein 2 (TMED2) in oral squamous cell carcinoma (OSCC).
Methodology: A bioinformatics analysis was first conducted to explore TMED2 expression in OSCC and its relation with overall survival. The analysis results were further verified by assessing TMED2 expression levels in human normal oral keratinocyte cells and human OSCC cell lines using quantitative real-time polymerase chain reaction and the Western blot.
