There is a lack of an accurate diagnostic method to predict occult lymph node metastasis and to help surgeons make precise treatment decisions. Aim: To construct and evaluate a preoperative diagnostic method to predict occult lymph node metastasis (OCLNM) in early-stage oral and oropharyngeal squamous cell carcinoma (OC and OP SCC) based on deep learning features (DLFs) and radiomics features. Methods: A total of 319 patients diagnosed with early-stage OC or OP SCC were retrospectively enrolled and divided into training, test and external validation sets. Traditional radiomics features and DLFs were extracted from their MRI images. The least absolute shrinkage and selection operator (LASSO) analysis was employed to identify the most valuable features. Prediction models for OCLNM were developed using radiomics features and DLFs. The effectiveness of the models and their clinical applicability were evaluated using the area under the curve (AUC), decision curve analysis (DCA) and survival analysis.
The optimal interval between neoadjuvant chemradiotherapy and esophagectomy is still a question that needs to be explored for patients with esophageal squamous cell carcinoma. In this study, based on previous studies, the investigators divided patients into two groups with a cutoff value of 50 days. By comparing the overall survival and disease-free survival of the entire population and non PCR population, the investigators ultimately obtained the optimal surgical timing suitable for clinical use
This study aimed to analyze perioperative information in patients with high-grade squamous intraepithelial lesion (HSIL) undergoing total hysterectomy (TH), offering insights into optimal surgery timing, selecting the operation path, and enhancing surgical operation details.
Patients with biopsy-verified oropharyngeal squamous cell carcinoma or Human Papillomavirus (HPV)-positive unknown primary treated with transoral robotic surgery are included. Immediately post-operatively, freshly resected specimens are examined with ex vivo 3D ultrasound (US). Ex vivo 3D US will be used to match US slices of the specimen with corresponding histopathology slices. The US slices will be reviewed by a panel of head and neck surgeons blinded to histopathology. The primary aim is to explore perioperative ex vivo 3D US for oropharyngeal tumor detection, delineation from normal tissue, tumor size and volume, and margin assessment.
We sought to comprehend the rates and causes of unplanned hospital readmission within 60 days following oral cancer surgery
Existing models do poorly when it comes to quantifying the risk of Lymph node metastases (LNM). This study generated elastic net regression (ELR), random forest (RF), extreme gradient boosting (XGB), and a combined (ensemble) model of these for LNM in patients with T1 esophageal squamous cell carcinoma.
The goal of this multicenter retrospective cohort study is to evaluate the impact of different pathological regression types on survival and recurrence patterns, with a particular focus on ypT0N+ patients in patients with esophageal squamous cell carcinoma. The main questions it aims to answer are the survival and recurrence patterns among the different pathological regression types in patients with esophageal squamous cell carcinoma after neoadjuvant chemoradiotherapy.
Retrospective analysis of the presence and maturity of tertiary lymphoid structures in pathological sections of patients with esophageal squamous cell carcinoma after surgical treatment. Pay attention to the overall survival and disease free survival of these esophageal squamous cell carcinoma patients.
This study is a multi-center, non-interventional study. Clinicopathologic, treatment , outcome and efficacy data will be collected from medical records in metastatic esophageal squamous cell carcinoma (ESCC) patients.
Patients with liver metastasis from esophagus squamous (ESC) are usually offered systemic therapy. However, for those with predominant liver disease or failure of system therapy, local liver management becomes an option. This prospective single center study aimed to evaluate the efficacy and adverse events of hepatic arterial infusion chemotherapy (HAIC) using percutaneous catheter placement techniques for liver metastases from esophagus squamous (ESC).
