Salivary adenoid cystic carcinoma is a very common malignant neoplasm in the salivary glands. One of the most important features of salivary cystic carcinoma is perineural invasion, which renders its complete removal is very difficult through clinical surgery. Consequently, tumor recurrence occurs easily after clinical surgery. Therefore, the molecular mechanisms of perineural invasion in salivary adenoid cystic carcinoma are necessary to explore. These mechanisms are reviewed in this paper.

BACKGROUND: Clonal naevi are characterized by a focal proliferation of pigmented melanocytes in an otherwise banal naevus. These subclones are often composed of aggregates of larger, epithelioid melanocytes with nuclear atypia and dusty-grey cytoplasmic pigmentation, which are referred to as 'pulverocytes', and this finding may lead to a misdiagnosis of malignant melanoma (MM). AIM: To characterize the significance of subclones of dusty-grey pigmented epithelioid melanocytes within spitzoid neoplasms...

Recurrence and second primary cancer (SPC) continue to represent major obstacles to long-term survival in head and neck cancer (HNC). Our aim was to evaluate whether established demographics, lifestyle-related risk factors for HNC and clinical data are associated with recurrence and SPC in HNC. We conducted a multicentre study by using data from five studies members of the International Head and Neck Cancer Epidemiology consortium-Milan, Rome, Western Europe, Sao Paulo, and Japan, totalling 4005 HNC cases with a median age of 59 (interquartile range 52-67)...

BACKGROUND: Glioblastoma multiforme (GBM) is the most malignant of brain tumors. Acquired drug resistance is a major obstacle for successful treatment. Earlier studies reported that expression of the multiple drug resistance gene (MDR1) is regulated by YB-1 or NFκB via the JNK/c-Jun or Akt pathway. Over-expression of the Dickkopf (DKK) family member DKK3 by an adenovirus vector carrying DKK3 (Ad-DKK3) exerted anti-tumor effects and led to the activation of the JNK/c-Jun pathway. We investigated whether Ad-DKK3 augments the anti-tumor effect of temozolomide (TMZ) via the regulation of MDR1...

PURPOSE: Dedicated breast positron emission tomography (DbPET) provides detailed high-resolution images and can detect intratumoral heterogeneity using 18 F-fluorodeoxyglucose (FDG). We aimed to evaluate the correlation between FDG uptake on DbPET and the clinicopathological features of breast cancer, particularly those with an intratumoral heterogeneous distribution of FDG on DbPET. METHODS: We evaluated 195 consecutive patients with invasive breast cancer who underwent preoperative whole-body PET (WBPET) and DbPET concurrently between January 2016 and March 2017...

PURPOSE: Pheochromocytomas (PCCs) exhibit malignant potential, but current histological modalities for the proper detection of aggressive behavior are debated. The two most widespread algorithms are the "Pheochromocytoma of the Adrenal Gland Scaled Score" (PASS) and the "Grading System for Adrenal Pheochromocytoma and Paraganglioma" (GAPP), both which mostly rely on histological parameters to identify PCC patients at risk of disseminated disease. Since the algorithms are derived from studies using predominantly sporadic PCCs, little is known whether the PASS or GAPP scores can predict malignant potential in hereditary cases...

Collision tumours of the uterine cervix are extremely uncommon with exact incidence not known. Unlike squamous cell carcinoma (SCC) and adenocarcinoma that are known to coexist, small cell neuroendocrine carcinoma (SCNEC) is rarely documented with other histological types in the cervix. We report such rare case of a collision tumour in cervix displaying dual histological component of SCNEC and SCC in a 36-year-old woman. The case is being presented because of its rarity and represents a unique and hitherto seldom-reported combination of two malignant tumours with distinct and often contrasting epidemiology, histology and prognosis coexisting in the same patient...

Hematopoietic stem cell transplantation is a curative treatment for many hematologic malignancies with its most important side effect being graft-versus-host disease (GVHD). Herein, we present a 3.5 year-old male with weight of 9.8 kg with acute GVHD (grade IV gastrointestinal and cutaneous) who did not respond to the first line therapies (corticosteroids). Thus, the patient was a candidate for extracorporeal photochemotherapy (ECP). Due to the hyperbilirubinemia, two sessions of ECP every week as well as one session of plasmapheresis 24 h before each ECP session were performed (Spectra™ Optia® apheresis system)...

T-cell acute lymphoblastic leukaemia (T-ALL) is a hematological malignancy caused by the accumulation of genomic lesions that affect the development of T-cells. ZEB1, a member of zinc finger-homeodomain family transcription factor, exhibits crucial function in promoting T-cell differentiation and potentially acts as a tumor suppressor in T-ALL. However, the molecular mechanism by which ZEB1 regulates T-ALL leukaemogenesis remains obscure. Here, we showed that oncogenic LIM only 2 (LMO2) could recruit Sap18 and HDAC1 to assemble an epigenetic regulatory complex, thus inducing histone deacetylation in ZEB1 promoter and chromatin remodeling to achieve transcriptional repression...

PURPOSE: Lung cancer is a multifactorial malignancy for which some risk factors, such as chronic lung diseases, their interactions with smoking, and how they differ by race and sex, are not fully understood. We investigated the associations between chronic inflammatory lung disease and non-small cell lung carcinoma (NSCLC) and how sex and race may affect such associations. METHODS: Using logistic regression, we analyzed 1660 lung cancer cases and 1959 population controls and estimated adjusted odds ratios (AORs) and 95% confidence intervals (CIs)...

Renal cell carcinoma (RCC) is the most common malignancy of kidney and remains largely intractable once it recurs after resection. mTOR inhibitors have been one of the mainstays used against recurrent RCC; however, there has been a major problem of the resistance to mTOR inhibitors, and thus new combination treatments with mTOR inhibitors are required. We here retrospectively showed that regular use of antilipidemic drug statins could provide a longer progression free survival (PFS) in RCC patients prescribed with an mTOR inhibitor everolimus than without statins (median PFS, 7...

Gallbladder cancer (GBC) is the most common malignancy of the biliary tract and its molecular pathogenesis is poorly understood. Aberrant expression of epithelial membrane protein-3 (EMP3) was reported in different kinds of cancers. Our study aimed to explore the elusive functional roles and the underlying molecular mechanisms of EMP3 with respect to GBC progression. The results showed that human GBC tissues exhibited decreased levels of EMP3 compared with non-malignant tissues. Kaplan-Meier analysis indicated that low expression of EMP3 was associated with poor prognosis of GBC patients...

BACKGROUND AND AIM: Studies have reported that Zinc finger E-box binding homeobox 1 antisense 1 (ZEB1-AS1) is overexpressed in many malignant tumors. However, the sample size in those studies was limited, so the clinicopathological and prognostic value of ZEB1-AS1 in solid tumors remains undetermined, Accordingly, the aim of this meta-analysis was to evaluate the relationship between the expression of lncRNA ZEB1-AS1 and clinicopathological characteristics and prognosis in patients with solid tumors...
