Esophageal cancer as the sixth common cause of cancer death in the world consists of different histological types with various incidence patterns. Among them, esophageal adenocarcinoma and esophageal squamous cell carcinoma are the most prevalent types which also have different causality, cell of origin and risk factors. Since epidemiological studies have announced consumption of hot substances as one of the major risk factors for squamous cell carcinoma, evaluating the effect of this external stress on esophagus cells seems desirable...

Oesophageal cancer is the sixth most common cause of cancer-related death worldwide and is therefore a major global health challenge. The two major subtypes of oesophageal cancer are oesophageal squamous cell carcinoma (OSCC) and oesophageal adenocarcinoma (OAC), which are epidemiologically and biologically distinct. OSCC accounts for 90% of all cases of oesophageal cancer globally and is highly prevalent in the East, East Africa and South America. OAC is more common in developed countries than in developing countries...

Lung cancer risk and tumor characteristics differ between sexes. Estrogen has been suggested to counteract lung cancer development. We aimed to test the hypothesis that digitalis use decreases lung cancer risk due to its estrogenic and other anticancer properties in men. This was a nationwide Swedish population-based cohort study between July 1, 2005 and December 31, 2013. Data on the use of digitalis and organic nitrates in all male individuals were derived from the Swedish Prescribed Drug Registry. New lung cancer diagnoses among cohort participants were identified from the Swedish Cancer Registry...

Although conventional chemoradiotherapy is effective for most anal squamous cell carcinoma (ASCC) patients, HPV-negative ASCC patients respond poorly to this treatment and new therapeutic approach is required. Our group has previously established an HPV-negative ASCC mouse model and demonstrated that signal transducer and activation of transcription 3 (STAT3) is hyper-activated in the model. Here, we show that in vivo inhibition of STAT3 by S3I-201 effectively delays tumor growth in ASCC mouse model indicated by significantly smaller tumor size and burden in the treatment group compared with control group at the same point...

INTRODUCTION: Recent evidence suggests that the local renin-angiotensin system has been implicated in various malignancies. The mitochondrial assembly receptor is a newly identified receptor for angiotensin peptides, angiotensin-(1-7), and has an important role in the renin-angiotensin system. However, the role of the mitochondrial assembly receptor in the prognosis of cancer patients remains unclear. The aim of this study was to evaluate the significance of mitochondrial assembly receptor signaling in the prognosis of oral tongue squamous cell carcinoma...

Oral squamous cell carcinoma (OSCC) is a disfiguring malignancy and significantly impacts the quality of patient's life. Kallikrein-related peptidase 4 (KLK4), which is closely related to cancers, is highly expressed in OSCC. To explore the biological function of KLK4 in OSCC, a KLK4-specific shRNA was used to silence its endogenous expression, and then the migration and invasion of OSCC cells were explored. Results of our study showed that silencing KLK4 inhibited the migration and invasion of OSCC cells. The protein levels of epithelial mesenchymal transition-associated markers and proteases were also altered by KLK4 silencing...

BACKGROUND: Neoadjuvant chemotherapy in pure urothelial bladder cancer provides a significant survival benefit. However, to the authors' knowledge, it is unknown whether this benefit persists in histological variants. The objective of the current study was to assess the effect of neoadjuvant chemotherapy on the probability of non-organ-confined disease and overall survival after radical cystectomy (RC) in patients with histological variants. METHODS: Querying the National Cancer Data Base, the authors identified 2018 patients with histological variants who were undergoing RC for bladder cancer between 2003 and 2012...
