Activation of the nuclear factor (erythroid-derived 2)-like 2 (NFE2L2 or NRF2) transcription factor is a critical and evolutionarily conserved cellular response to oxidative stress, metabolic stress, and xenobiotic insult. Deficiency of NRF2 results in hypersensitivity to a variety of stressors, whereas its aberrant activation contributes to several cancer types, most commonly squamous cell carcinomas of the esophagus, oral cavity, bladder, and lung. Between 10 and 35% of patients with squamous cell carcinomas display hyperactive NRF2 signaling, harboring activating mutations and copy number amplifications of the NFE2L2 oncogene or inactivating mutations or deletions of KEAP1 or CUL3, the proteins of which co-complex to ubiquitylate and degrade NRF2 protein.

Organ transplant recipients (OTRs) have an elevated risk for keratinocyte cancers (KC); basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). We assessed whether polygenic risk scores (PRSs) generated in non-transplantees from the UK Biobank and 23andMe (13,981 SCC, 33,736 BCC, and >560,000 controls), can predict KC risk in an independent OTR cohort.

Purpose: Parastomal recurrence of squamous cell carcinoma (SCC) with tracheal involvement following salvage total laryngectomy after prior concurrent chemoradiotherapy is one of the most insidious challenges in head and neck surgery because a complex reconstruction is often required for covering a large area of skin loss, filling the dead space beneath, tracheal reconstruction and suspension, and tracheostome resurfacing. The aim is to describe our experience with the internal mammary artery perforator (IMAP) propeller flap for tracheal and tracheostome reconstruction and neck resurfacing after parastomal and cervical trachea resection, especially for suspension and anchoring the stump of the residual distal trachea to the island flap itself.

Methods: We describe IMAP flap reconstruction after resection of parastomal recurrence of SCC requiring cervical trachea resection in five patients between January 1, 2005 and August 30, 2019. Read More

Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide, with reported incidences of ~800 000 cases each year. One of the critical determinants in patient response to radiotherapy, particularly for oropharyngeal cancers, is human papillomavirus (HPV) status where HPV-positive patients display improved survival rates and outcomes particularly because of increased responsiveness to radiotherapy. The increased radiosensitivity of HPV-positive HNSCC has been largely linked with defects in the signalling and repair of DNA double-strand breaks. Read More
