Proc SPIE Int Soc Opt Eng 2021 Feb 15;11598. Epub 2021 Feb 15.

Dept. of Robotics Engineering, Worcester Polytechnic Institute, Worcester, MA, USA.

Office-based endoscopic laser surgery is an increasingly popular option for the treatment of many benign and pre-malignant tumors of the vocal folds. While these procedures have been shown to be generally safe and effective, recent clinical studies have revealed that there are a number of challenging locations inside the larynx where laser light cannot be easily delivered due to line-of-sight limitations. In this paper, we explore whether these challenges can be overcome through the use of side-firing laser fibers. Read More

Potential Therapeutic Significance of Laminin in Head and Neck Squamous Carcinomas.

Cancers (Basel) 2021 Apr 15;13(8). Epub 2021 Apr 15.

Laboratório de Interações Celulares, Instituto de Ciências Biomédicas, Prédio de Ciências da Saúde-Cidade Universitária, Universidade Federal do Rio de Janeiro-UFRJ, Ilha do Fundão, A. Carlos Chagas, 373-bloco F, sala 26, Rio de Janeiro 21941-902, Brazil.

Head and neck squamous cell carcinomas (HNSCC) are among the most common and lethal tumors worldwide, occurring mostly in oral cavity, pharynx, and larynx tissues. The squamous epithelia homeostasis is supported by the extracellular matrix (ECM), and alterations in this compartment are crucial for cancer development and progression. Laminin is a fundamental component of ECM, where it represents one of the main components of basement membrane (BM), and data supporting its contribution to HNSCC genesis and progression has been vastly explored in oral cavity squamous cell carcinoma.

Vocal-cord Only vs. Complete Laryngeal radiation (VOCAL): a randomized multicentric Bayesian phase II trial.

BMC Cancer 2021 Apr 22;21(1):446. Epub 2021 Apr 22.

Radiation Oncology Department, Western University, London, Ontario, Canada.

Background: Radiotherapy, along with laser surgery, is considered a standard treatment option for patients with early glottic squamous cell cancer (SCC). Historically, patients have received complete larynx radiotherapy (CL-RT) due to fear of swallowing and respiratory laryngeal motion and this remains the standard approach in many academic institutions. Local control (LC) rates with CL-RT have been excellent, however this treatment can carry significant toxicities include adverse voice and swallowing outcomes, along with increased long-term risk of cerebrovascular morbidity.

Perineural Invasion As the Sole Pathologic Risk Factor After Surgical Resection for Head and Neck Squamous Cell Carcinoma.

Cureus 2021 Feb 3;13(2):e13094. Epub 2021 Feb 3.

Radiation Oncology, Wake Forest School of Medicine, Winston-Salem, USA.
