Sinonasal squamous cell carcinoma (SNSCC) is an aggressive cancer affecting the nasal and sinus regions, with its progression factors, particularly genetic ones, not yet fully understood. Here, we first conducted a retrospective study with 219 SNSCC patients to identify clinical factors affecting SNSCC prognosis. Additionally, we mined a vast literature dataset to uncover genetic factors associated with SNSCC progression.

Exosomes from M2 macrophages were isolated and characterized using transmission electron microscopy, nanoparticle tracer analysis and western blot. Expression of HOXC13-AS, miR-485-5p, IGF2BP2, and PD-L1 was analyzed.

Sakuranin is a flavanone which is a class of flavonoids found abundantly in Prunus species. Flavonoids have been long known for their anticancer properties against a range of human cancers. However, there are no previous reports on the anticancer effects of sakuranin flavanone molecule.

Here, we constructed a nanodrug delivery system (HA/Au-PDA@CZT) that targets tumors and responds to pH and near-infrared (NIR) dual stimuli. By precisely interacting with an overexpressed CD44 receptor in specific cancer cells, hyaluronic acid (HA) is coated on the Au-PDA NP surface for tumor-targeting abilities.

Head and neck squamous cell carcinoma are one of the most common types of cancer worldwide. Although a variety of treatment methods such as surgery, radiotherapy, chemotherapy, and targeted therapy are widely used in diagnosing and treating HNSCC, the survival prognosis of patients has not been significantly improved in the past decades. As an emerging treatment approach, immunotherapy has shown exciting therapeutic effects in R/M HNSCC.

They have many similarities in embryology, histology, and anatomy, but their advantages and disadvantages in head and neck repair have not been fully recognized. This study aimed to compare the cadaveric anatomy and clinical application of FPTF and FRFF for the reconstruction of head and neck defects after tumor resection.

Objective: To investigate the clinicopathological characteristics of papillary thyroid cancer (PTC) and identify risk factors for postoperative recurrence of PTC with recurrent laryngeal nerve (RLN) involvement.
Methods: In total, 171 patients (112 women and 59 men, age: 18-80 years, and 65 patients aged ≥ 55) with T4a PTC with RLN involvement, treated at Beijing Tongren Hospital, Capital Medical University, from January 2006 to December 2020, were retrospectively examined. Clinicopathological characteristics, including voice analysis results, and survival outcomes were assessed.
Objective: To investigate the feasibility and effect of a pedicled submental flap in postoperative defect repair of nasopharyngeal malignant tumors.
Methods: Eight cases (six women, two men; age, 29-63 years) of postoperative defects after resection of malignant nasopharyngeal tumors with a lesion stage of (r) TNM were retrospectively analyzed. Preoperative enhanced thin-slice computed tomography of the neck was performed to predict the submental flap reflux vein.
Purpose: the purpose of this study was to screen peripheral blood parameters and construct models predicting the prognosis and induction chemotherapy (IC) response in locally advanced laryngeal squamous cell carcinoma (LSCC) patients.
Methods: A total of 128 stage III/IVa LSCC patients (who required a total laryngectomy) were enrolled in a retrospective study from January 2013 to September 2020 at Beijing Tongren Hospital of Capital Medical University. Among them, 62 patients received IC (IC group), and 66 patients immediately underwent a total laryngectomy (TL) after diagnosis (surgery group).
Objective: To investigate a novel combined microinvasive trans-submandibular and nasendoscopy surgical approach for nasopharyngeal carcinoma involving the parapharyngeal space.
Methods: Seven patients diagnosed with nasopharyngeal carcinoma involving the parapharyngeal space between May 2018 and April 2021, two males and five females, aged 37-63 years.Six of the 7 patients underwent submental flap preparation and dissection of the lymph nodes in the upper neck and parapharyngeal space on the lesion side.
Determination of human papillomavirus (HPV) status has become clinically relevant for head and neck squamous cell carcinoma (HNSCC) patients. p16 immunohistochemistry is one of the recommended methods for classifying HPV status. However, long noncoding RNAs (lncRNAs) and related competing endogenous RNA (ceRNA) networks linked to different p16-status HNSCC are still absent.

Introduction: Papillary thyroid microcarcinoma (PTMC) is a specific subgroup of papillary thyroid carcinoma and defined with the dimension ≤1 cm by the WHO. Although it shows a relatively high 10-year livability, the metastasis of PTMC into other tissues and organs seriously affects the daily life of patients with relatively high mortality. Therefore, the genetic basis for the metastasis of PTMC needs to be explored for effective therapeutic targets.

Multiple risk factors have been described for the development of local recurrence after treatment. However, to date, there is no analysis or systematic review investigating the relationships between clinical and histopathological factors and the appearance of local recurrence after transoral CO laser microsurgery in T1b-T2 glottic carcinoma patients.
