There are many histologic types of gynecologic malignancies. I reviewed three rare ovarian tumor types that have poor prognoses. Ovarian mesonephric-like adenocarcinoma (MLA) is a newly described histological type known for its aggressive behavior.

Background And Purpose: Understanding the cellular and molecular effect of proton radiation, particularly the increased DNA damage complexity at the distal end of the Bragg curve, is current topic of investigation. This work aims to study clonogenic survival and DNA damage foci kinetics of a head and neck squamous cell carcinoma cell line at various positions along a double passively scattered Bragg curve. Complementary studies are conducted to gain insights into the link between cell survival variations, experimentally yielded foci and the number and complexity of double strand breaks (DSBs).

Department of Biophysics, Medical College of Wisconsin, Milwaukee, WI, United States.
Background And Purpose: Quantitative MRI (qMRI) has been explored for detecting tumor changes during radiation therapy (RT) in head and neck squamous cell cancer (HNSCC). Clinical trials show prolonged survival with PD-1 targeted immune checkpoint inhibition. Hypofractionated radiation regimens are being studied to counteract radioresistant clonogen formation.

Department of Head and Neck Surgical Oncology, Peter MacCallum Cancer Centre, Melbourne, Australia.
Objectives: Transoral robotic surgery (TORS) and transoral laser microsurgery (TOLM) plus neck dissection are viable alternatives to radiotherapy as a treatment modality in select cases of oropharyngeal squamous cell carcinoma. Many centers advocate for elective ligation of the feeding arteries at index neck dissection prior to TORS/TOLM to mitigate the risk of catastrophic perioperative hemorrhage. Although there are multiple cadaveric studies in the literature to identify the lingual artery at multiple points throughout its course, there are no studies on the intraoperative identification of the lingual artery for elective ligation prior to TORS/TOLM.

Introduction: Oral squamous cell carcinoma (OSCC) is one of the most common malignant tumors in oral and maxillofacial region. The development of new chemotherapy agents and new drug combinations may improve patient survival and quality of life, but both surgery and radiotherapy have significant functional side effects and drug resistance, ultimately resulting in a 5-year survival rate of no more than 60% for OSCC patients. Studies have shown that Brucea javanica oil (BJO) extracts have anti-cancer effects against a variety of cancers, but little research has been reported on OSCC.
