Perineural spread of tumour cells along cranial nerves is a severe complication of primary cutaneous squamous cell carcinomas of the head and neck region. While surgical excision of the tumour is the treatment of choice, removal of all the tumour is often complicated by the neural location and recurrence is frequent. Non-invasive immune treatments such as checkpoint inhibitor blockade may be useful in this set of tumours although little is understood about the immune response to perineural spread of squamous cell carcinomas...

BACKGROUND: Gallbladder cancer detected incidentally after cholecystectomy (IGBC) currently is the most common diagnosis of gallbladder cancer, and oncologic extended resection (OER) is recommended for tumors classified higher than T1b. However, the precise prognostic significance of residual cancer (RC) found at the time of OER has not been well established. This analysis aimed to determine the prognostic impact of RC found in patients with IGBC undergoing OER. METHODS: Outcomes for IGBC at a center for a low-incidence country (USA) and a high-incidence country (Chile) between January 1999 and June 2015 were analyzed...

Mortalin, an essential mitochondrial chaperone protein, is involved in the tumorigenesis of a number of malignancies. This study aimed to investigate the expression of Mortalin in pancreatic ductal adenocarcinoma (PDAC) cells and to determine its clinicopathological and prognostic significance. The localization of Mortalin protein was detected in BXPC-3 PDAC cells using immunofluorescence (IF). Immunohistochemistry (IHC) was also employed to detect Mortalin expression in well-defined tissues obtained from 106 PDAC patients and 46 corresponding non-tumor pancreatic tissues...

Squamous cell carcinoma (SCC) that originates in the pinna is thought to have a high risk of metastases (up to 16%) compared with under 5% for cutaneous SCC at any other site, and histological features of the primary tumour may provide evidence for further surveillance or treatment. To identify any association between histological features and the risk of metastases we made an electronic search of the histopathological records at the University Hospital Southampton NHS Foundation Trust for all patients who presented with auricular SCC from 2007-2012...
