The incidence of human papillomavirus–positive (HPV+) head and neck squamous cell carcinoma (HNSCC) has surpassed that of cervical cancer and is projected to increase rapidly until 2060. The coevolution of HPV with transforming epithelial cells leads to the shutdown of host immune detection. Targeting proximal viral nucleic acid–sensing machinery is an evolutionarily conserved strategy among viruses to enable immune evasion. However, E7 from the dominant HPV subtype 16 in HNSCC shares low homology with HPV18 E7, which was shown to inhibit the STING DNA-sensing pathway. The mechanisms by which HPV16 suppresses S...

Authors: He H, Li PC, Jia W, Hu B, Ji CS Abstract BACKGROUND Recently, targeted therapy for malignant tumors has developed rapidly, but there is still no effective targeted therapy for advanced esophageal squamous cell carcinoma (ESCC). Methylenetetrahydrofolate dehydrogenase 2 (MTHFD2) is a key enzyme involved in folate metabolism and is closely related to the proliferation in many cancers. However, few studies have explored the expression of MTHFD2 in ESCC and its prognostic significance. MATERIAL AND METHODS The expressions of MTHFD2, ki67, and p53 in ESCC tissues were detected by immunohistochemistry. Further, ...

AbstractExtranodal extension (ENE) is a significant prognostic factor in p16-negative head and neck squamous-cell carcinoma and is classified as N3b by the American Joint Committee on Cancer 8th edition. While most previous radiological studies have focused on the diagnostic performance of pathological ENE, radiologists should be able to provide more clinically relevant information on this entity. The purpose of this article is to review the clinical implications of ENE, to describe key imaging features of ENE with clinical and histopathological correlations and to discuss evaluation of ENE for clinical staging, treatment ...

This study was registered with PROSPERO (No. CRD42019127761). A total of 28 studies, which included 13,748 lung cancer cases and 23,112 controls, were used for this meta-analysis. The pooled OR indicated that the highest residential radon exposure was significantly associated with an increased risk of lung cancer (OR = 1.48, 95% CI = 1.26–1.73). All histological types of lung cancer were associated with residential radon. Strongest association with small-cell lung carcinoma (OR = 2.03, 95% CI = 1.52–2.71) was found, followed by adenocarcinoma (OR = 1.58, 95% CI = 1.31–1.91), other histological...

CONCLUSION: Complications remain hard to predict and there are continuing causes of morbidity. Additionally, prior treatment continues to affect surgical outcomes. PMID: 32079554 [PubMed - as supplied by publisher]

CONCLUSION: Repeat transoral laser microsurgery can be an oncologically safe alternative to other salvage therapies for glottic squamous cell carcinoma recurrence, without sacrificing functional outcomes. PMID: 32079549 [PubMed - as supplied by publisher]

Authors: Hessam S, Bechara FG Abstract Hidradenitis suppurativa/acne inversa (HS/AI) is a chronic inflammatory skin disease. Several studies showed that perianal, perineal and gluteal involvement is more common in men. Axillary, submammary and inguinal localizations seem to be more prevalent in women. Involvement of the genitoanal region is associated with a higher reduced quality of live and sexual health compared to other locations. Moreover HS/AI in the genitoanal region can lead to serious complications. The knowledge of perianal fistula formation, pubogenital lymphedema and squamous cell carcinoma, w...

Authors: Jabalee J, Towle R, Lawson J, Dickman C, Garnis C Abstract Neutral sphingomyelinase 2 (nSMase2), the product of the sphingomyelin phosphodiesterase 3 (SMPD3) gene, catalyzes the hydrolysis of sphingomyelin to ceramide. Ceramide acts on various signaling pathways to influence cell proliferation, survival, and stress response. Altered levels of sphingolipids and ceramides have been reported in various cancer types, including oral squamous cell carcinoma (OSCC). OSCC patients exhibit a poor 5-year survival rate of 50%, a figure that has remained stagnant for decades. To overcome this requires a better underst...
