Larynx cancer is a therapeutically challenging disease. Rapidly evolving experimentally validated data have significantly improved our understanding of the complex role of numerous RNA, DNA, and proteins that play a role in the development and progression of cancer. Based on the insights from approximately two decades of research, it seems clear that microRNAs (miRNAs) have revolutionized our concepts related to the main role of noncoding RNAs in different cancers' progression, development, and metastasis. Mechanistically, miRNAs have been reported to regulate different RNAs and finally protein-coding genes. The expression profiling of miRNAs and messenger RNA (mRNAs) was conducted for a deeper analysis of the miRNAs and mRNAs which play an essential role in larynx cancer. Downregulation or upregulation over twofolds in the miRNAs was considered to be significant, and that of sixfolds or below was considered to be significant for the mRNAs. In accordance with this approach, the expression levels of 43 miRNAs were increased in this study, whereas the expression levels of 129 were decreased. Accordingly, all the genomic expression studies provided evidence of upregulation of 97 genes, whereas 128 genes were found to be downregulated. Among these miRNAs, hsa-miR-20a-3p and hsa-miR-1972 were noted to be important in the etiology of larynx cancer.

Accelerated Low-Dose Total Skin Electron Beam Therapy Using the Modified Stanford Technique: An In Vivo Dosimetry Confirmation Study.
Cureus

Radiation Oncology, Thomas Jefferson University Hospital, Philadelphia, USA.
Purpose Low-dose total skin electron beam therapy (LD-TSEBT) has recently gained popularity in treating mycosis fungoides (MF) due to its reduced toxicity and favorable response rates. Combining accelerated LD-TSEBT with the modified Stanford technique (mST), a condensed cycling approach, offers a promising and convenient option. However, in vivo dosimetry data confirming the effectiveness of this approach is limited.

Department of Otorhinolaryngology Head and Neck Surgery, Tianjin First Central Hospital, Tianjin, China.
Background: The early diagnosis of glottic laryngeal cancer is the key to successful treatment, and machine learning (ML) combined with narrow-band imaging (NBI) laryngoscopy provides a new idea for the early diagnosis of glottic laryngeal cancer.
Objective: To explore the clinical applicability of the diagnosis of early glottic cancer based on ML combined with NBI.
Material And Methods: A retrospective study was conducted on 200 patients diagnosed with laryngeal mass, and the general clinical characteristics and pathological results of the patients were collected.
Lymph Node Metastasis for pN+ Superficial Esophageal Squamous Cell Carcinoma.

Department of Thoracic Surgery, National Cancer Center/Cancer Hospital, Chinese Academy of MedicalSciences and Peking Union Medical College, Beijing, China.
Objectives: This study aimed to analyze lymph node metastasis (LNM) distribution in superficial esophageal squamous cell carcinoma (ESCC) and its impact factors on survival.
Methods: We reviewed 241 pT1N+ ESCC cases between February 2012 and April 2022 from 10 Chinese hospitals with a high volume of esophageal cancer (EC). We analyzed clinicopathological data to identify overall survival (OS) risk factors and LNM distribution in relation to tumor invasion depth.

Clinic for Otorhinolaryngology, University Hospital Leipzig, Leipzig, Germany.
Introduction: The larynx organ preservation (LOP) trial DeLOS-II enrolled = 173 patients with advanced laryngeal/hypopharyngeal squamous cell carcinoma (LHSCC) amenable (only curatively resectable) through total laryngectomy (TL) to receive induction chemotherapy (IC) with TPF [docetaxel (T), cisplatin (P), and 5-fluorouracil (F)] (arm A, 85 patients) or additional cetuximab (E) weekly (arm B, 88 patients). Responders with endoscopic estimated tumor surface shrinkage (ETSS) ≥30% after 1 cycle IC (IC-1) received a further two cycles of IC followed by radiotherapy (RT), whereas TL was recommended for non-responders. Arm B failed to show superior 24-month laryngectomy-free survival (LFS) and overall survival (OS), the protocol-specified primary and secondary endpoints.

Purpose: The incidence and survival rates of head and neck squamous cell carcinoma (HNSCC) and nasopharyngeal carcinoma (NPC) vary globally, influenced by factors such as ethnicity, lifestyle, and health care systems.
Methods: A retrospective analysis was conducted on patients with HNSCC treated between 2008 and 2020 in four major Thai academic cancer centers, using a multidisciplinary multicenter database. The study focused on the evolution of patient characteristics, survival changes, and treatment landscape alterations over time.
