NID1 promotes laryngeal cancer stemness via activating WNT pathway.

Background: Laryngeal cancer (LCA) is one of the most common head and neck squamous cell carcinoma with poor outcome. LCA stem cells are the main reason for LCA therapy resistance and relapse. Understanding the molecular mechanisms of the self-renew of LCA stem cells is critical to develop now targets and strategies for LCA therapy.

Communication between cancer cell subtypes by exosomes contributes to nasopharyngeal carcinoma metastasis and poor prognosis.

Background: Intratumor heterogeneity is common in cancers, with different cell subtypes supporting each other to become more malignant. Nasopharyngeal carcinoma (NPC), a highly metastatic cancer, shows significant heterogeneity among its cells. This study investigates how NPC cell subtypes with varying metastatic potentials influence each other through exosome-transmitted molecules.

Comprehensive analysis of endoplasmic reticulum stress related signature in head and neck squamous carcinoma.

Head and neck squamous carcinoma (HNSC) is a prevalent malignant disease, with the majority of patients being diagnosed at an advanced stage.

This study aimed to explore the utility of PNI in ATC.

Risk factors of transient and permanent hypoparathyroidism after thyroidectomy: a systematic review and meta-analysis.

Background: Postoperative hypoparathyroidism (hypoPT) is a common complication following thyroid surgery. However, current research findings on the risk factors for post-thyroid surgery hypoPT are not entirely consistent, and the same risk factors may have different impacts on transient and permanent hypoPT. Therefore, there is a need for a comprehensive study to summarize and explore the risk factors for both transient and permanent hypoPT after thyroid surgery.

Efficacy and safety of pralsetinib in Chinese advanced RET-mutant medullary thyroid cancer patients.

Pralsetinib has demonstrated efficacious activity in various solid tumors, including medullary thyroid cancer (MTC), as observed in the phase 1/2 global ARROW study (BLU-667-1101; NCT03037385). We evaluated the safety and efficacy of pralsetinib in Chinese patients with advanced RET-mutant MTC. In the extension cohort of ARROW, adult patients with advanced MTC, who had not received systemic therapy (except for cytotoxic chemotherapy), were treated with pralsetinib (400 mg once daily, orally).

Epigenetic signature discriminates lymphatic metastasis in wild-type thyroid carcinoma: methylation role of .

Conservative treatment approaches for thyroid carcinoma (TC) patients with wild-type B-type Raf kinase () pose risks of long-term recurrence. The association of DNA methylation with TC metastasis is unclear. Here we analyzed data from 179 wild-type TC patients in the The Cancer Genome Atlas database, identifying significant metastasis-associated CpGs.

Risk factors and predictive model for recurrence in papillary thyroid carcinoma: a single-center retrospective cohort study based on 955 cases.

Background: The 2015 American Thyroid Association guidelines proposed recurrence risk stratification of differentiated thyroid carcinoma, including papillary thyroid carcinoma (PTC), but this stratification excluded non-initial treatment patients with worse outcomes. This study aimed to explore the potential risk factors for recurrence in PTC and develop a predictive model for both initial and non-initial treatment of patients with PTC.

Methods: A total of 955 patients were included in this study.

Intratumor microbiome: selective colonization in the tumor microenvironment and a vital regulator of tumor biology.

The polymorphic microbiome has been proposed as a new hallmark of cancer. Intratumor microbiome has been revealed to play vital roles in regulating tumor initiation and progression, but the regulatory mechanisms have not been fully uncovered. In this review, we illustrated that similar to other components in the tumor microenvironment, the reside and composition of intratumor microbiome are regulated by tumor cells and the surrounding microenvironment.

Contrast-enhanced US with Perfluorobutane to Diagnose Small Lateral Cervical Lymph Node Metastases of Papillary Thyroid Carcinoma.

Background Although metastasis of lateral cervical lymph nodes (LNs) is common in papillary thyroid carcinoma (PTC), correctly diagnosing small metastatic LNs with US remains challenging. The use of contrast-enhanced US (CEUS), especially the postvascular phase of CEUS with perfluorobutane contrast material, might contribute to improved diagnosis of metastatic LNs in PTC. Purpose To assess the diagnostic value of the postvascular phase of CEUS with perfluorobutane in suspicious small lateral cervical LNs (short-axis diameter ≤8 mm) in patients with PTC.

Analysis of T1-T2 stage oropharyngeal squamous cell carcinoma treated with transoral robotic surgery.

Objective: Transoral robotic surgery (TORS) has become an effective treatment for early-stage oropharyngeal squamous cell carcinomas (OPSCCs). We aimed to analyze the clinical safety and efficacy of TORS for human papilloma virus (HPV)-positive and HPV-negative OPSCC in China.

Methods: Patients with OPSCC of pT1-T2 stage who underwent TORS from March 2017 to December 2021 were analyzed.

Ultrasound-guided core needle biopsy for accessing laryngeal masses with unsatisfactory laryngoscopy and biopsy results.

Background: Laryngoscopy and biopsy is the standard techniques to sample and diagnose laryngeal neoplasms, but not all patients with laryngeal neoplasm are eligible for biopsy via laryngoscopy (e.g., submucosal neoplasms).

Prognostic Utility of Nutritional Risk Index in Patients with Head and Neck Soft Tissue Sarcoma.

Background: The nutritional risk index (NRI) is an excellent indicator of nutritional status and a significant prognostic factor in several malignancies, but the relationship between NRI and the prognosis of head and neck soft tissue sarcoma (HNSTS) patients remains unclear. The aim of this study was to investigate the role of NRI in patients with HNSTS.

Methods: We retrospectively reviewed patients with HNSTS between 1990 and 2021.

Early postoperative calcitonin-to-preoperative calcitonin ratio as a predictive marker for structural recurrence in sporadic medullary thyroid cancer: A retrospective study.

Background: Calcitonin (Ctn) is widely used as a marker in the diagnosis, prognosis, and postoperative follow-up of patients with medullary thyroid carcinoma (MTC). The prognostic value of postoperative calcitonin-to-preoperative calcitonin ratio (CR), reflecting the change in Ctn level of response to initial treatment, remains uncertain in long-term disease outcomes. This study aims to determine the cut-off value of CR for predicting structural recurrence and assess the prognostic role of CR in patients with MTC.

HPRT1 Promotes Chemoresistance in Oral Squamous Cell Carcinoma via Activating MMP1/PI3K/Akt Signaling Pathway.

Hypoxanthine phosphoribosyl transferase 1 (HPRT1) is traditionally believed to be a housekeeping gene. However, recent reports have indicated that HPRT1 overexpression is associated with a poor prognosis in various types of cancers. Using The Cancer Genome Atlas (TCGA), HPRT1 was found to be highly expressed in various cancer types, especially in head and neck squamous cell carcinoma (HNSCC).

Background: The objective of this study was to investigate the role and molecular mechanism of cyclin-dependent kinase 5 (CDK5) in regulating the growth of tongue squamous cell carcinoma (TSCC).

Methods: The authors used multiple methods to detect the levels of CDK5 expression in samples of TSCC and to explore the relation between CDK5 expression and various clinicopathologic factors. In vivo and in vitro cell experiments were performed to detect the proliferation, invasion, and migration of TSCC cells with CDK5 knockdown or overexpression.

Comparison of the value of ultrasound and enhanced magnetic resonance imaging in judging cervical lymph node metastasis in patients with oral cancer.

Background: Oral cancer is the twelfth largest malignant tumor in the world. Oral cancer is prone to lymph node metastasis in the early stages of the disease, and lymph node metastasis will directly affect the treatment and survival rate. Therefore, whether the lymph node metastasis can be accurately evaluated is of great significance to the treatment and prognosis of patients.
