Complex nasal reconstruction for skin cancer and posttraumatic deformity using a modified frontonasal flap - Case report.

Int J Surg Case Rep 2021 Apr 30;83:105944. Epub 2021 Apr 30.

Plastic and Aesthetic Surgery, AARE KLINIK, Bern, Switzerland. Electronic address:

Introduction And Importance: Reconstruction of the nasal tip is challenging, especially when large defects are associated with compromised nasal soft tissues and framework. The frontonasal flap is an axial-pattern myocutaneous flap from the glabella and nasal dorsum that allows for various modifications in flap design to cover medium sized defects of the nasal tip.

Case Presentation: A 66-year-old male patient presented with a large and ulcerated squamous cell carcinoma of the nasal tip that was associated with substantial posttraumatic damage of the nasal soft tissue envelope and cartilaginous vault of the dorsum. Read More

Extension of early esophageal squamous cell neoplasia into ducts and submucosal glands and the role of endoscopic ablation therapy.

Gastrointest Endosc 2021 May 8. Epub 2021 May 8.

Dept. of Gastroenterology and Hepatology, St. Antonius Hospital, Nieuwegein, the Netherlands;; Dept. of Gastroenterology and Hepatology, University Medical Center Utrecht, Utrecht University, Utrecht, the Netherlands;. Electronic address:

Background And Aims: Early esophageal squamous cell neoplasia (ESCN) is preferably treated with en-bloc endoscopic resection. Ablation might be an alternative for flat ESCN, but ESCN extension along the epithelial lining of ducts and submucosal glands (SMGs) might jeopardize ablation efficacy. Clinical studies suggest that local recurrence might arise from such buried ESCN niches after ablation. Read More

African Americans With p16+ and p16- Oropharyngeal Squamous Cell Carcinomas Have Distinctly Poor Treatment Outcomes Independent of Medical Care Access.

JCO Oncol Pract 2021 May;17(5):e695-e702

Department of Otolaryngology-Head and Neck Surgery, University Hospitals Cleveland Medical Center, Case Western Reserve University School of Medicine, Cleveland, OH.

Purpose: Human papilloma virus-positive (HPV+) oropharyngeal squamous cell carcinoma (OPSCC), diagnosed with p16 immunohistochemistry, is associated with favorable prognosis; however, this connection was established using European American (EA)-skewed populations. The impact of p16/human papillomavirus status on outcomes in African American (AA) OPSCC patients remains to be settled. In this study, we determine the association between cancer disparity and p16 status in an OPSCC cohort controlling for time to treatment initiation (TTI), a surrogate for medical care access.

Reprogramming of the esophageal squamous carcinoma epigenome by SOX2 promotes ADAR1 dependence.

Nat Genet 2021 May 10. Epub 2021 May 10.

Herbert Irving Comprehensive Cancer Center, Division of Digestive and Liver Diseases, Department of Medicine, Columbia University, New York, NY, USA.

Esophageal squamous cell carcinomas (ESCCs) harbor recurrent chromosome 3q amplifications that target the transcription factor SOX2. Beyond its role as an oncogene in ESCC, SOX2 acts in development of the squamous esophagus and maintenance of adult esophageal precursor cells. To compare Sox2 activity in normal and malignant tissue, we developed engineered murine esophageal organoids spanning normal esophagus to Sox2-induced squamous cell carcinoma and mapped Sox2 binding and the epigenetic and transcriptional landscape with evolution from normal to cancer.

A seven-gene signature to predict the prognosis of oral squamous cell carcinoma.

Oncogene 2021 May 10. Epub 2021 May 10.

University of Coimbra, Cytogenetics and Genomics Laboratory, Institute of Cellular and Molecular Biology, Faculty of Medicine, Coimbra, Portugal.

The prognosis of oral squamous cell carcinoma (OSCC) patients remains poor without implemented biomarkers in the clinical routine practice to help in the patient's management. With this study we aimed to identify specific prognostic biomarkers for OSCC using a whole genome technology as well as to verify the clinical utility of a head and neck cancer-specific multiplex ligation-dependent probe amplification (MLPA) panel. A genomic characterization of tumor samples from 62 OSCC patients was performed using array comparative genomic hybridization (aCGH) and a more straightforward and cost-effective molecular technology, MLPA.

Decoupling epithelial-mesenchymal transitions from stromal profiles by integrative expression analysis.

Nat Commun 2021 May 10;12(1):2592. Epub 2021 May 10.

Department of Molecular Cell Biology, Weizmann Institute of Science, Rehovot, Israel.

Epithelial-to-mesenchymal transition (EMT) is the most commonly cited mechanism for cancer metastasis, but it is difficult to distinguish from profiles of normal stromal cells in the tumour microenvironment. In this study we use published single cell RNA-seq data to directly compare mesenchymal signatures from cancer and stromal cells. Informed by these comparisons, we developed a computational framework to decouple these two sources of mesenchymal expression profiles using bulk RNA-seq datasets. Read More

A novel lncRNA LOLA1 may predict malignant progression and promote migration, invasion, and EMT of oral leukoplakia via the AKT/GSK-3β pathway.

J Cell Biochem 2021 May 10. Epub 2021 May 10.

Department of Oral Mucosal Diseases, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, College of Stomatology, National Center for Stomatology, National Clinical Research Center for Oral Diseases, Shanghai Key Laboratory of Stomatology, Shanghai Jiao Tong University, Shanghai, China.

Although dysregulation and dysfunction of long noncoding RNAs (lncRNAs) have been implicated in malignant behavior of oral squamous cell carcinoma (OSCC), whether aberrant lncRNAs play a role in the carcinogenesis of oral leukoplakia (OL) as the best-known precursor of OSCC remains undetermined. Differentially expressed lncRNAs in the occurrence and progression of OL were studied by microarray and quantitative reverse-transcription polymerase chain reaction (qRT-PCR). We found a novel key lncRNA n386251 that we named LOLA1 (lncRNA oral leukoplakia progressed associated 1) in the OL progression. Read More

Comparison of Two Major Staging Systems in Predicting Survival and Recommendation of Postoperative Radiotherapy Based on the 11th Japanese Classification for Esophageal Carcinoma After Curative Resection: A Propensity Score-Matched Analysis.

Ann Surg Oncol 2021 May 9. Epub 2021 May 9.

Department of Radiation Oncology, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Objective: The aim of this study was to compare the prognostic predictive power of the 11th Japan Esophageal Society (JES) staging system with the 8th edition of the American Joint Committee on Cancer (AJCC) staging system in patients with thoracic esophageal squamous cell carcinoma (TESCC), and to estimate the survival benefits of postoperative radiotherapy (PORT) based on a substage of the JES staging system.
