Nasopharyngeal carcinoma: Imaging features of unusual cancer in children

Conclusion Pediatric NPC is generally not suspected clinically until late into the disease process. Awareness that NPC can occur in children should prompt careful evaluation for distinctive radiographic features. Earlier diagnosis may then direct the patient to timely appropriate therapy when these key radiographic features are present and recognized.

Stage IV nasopharyngeal carcinoma (NPC) without distant metastasis is defined as clinically T4 or N3 disease in the American Joint Committee on Cancer (AJCC) and the International Union against Cancer Control (UICC) 8th edition [1]. This is either a locally infiltrative tumor with intracranial extension, involvement of cranial nerves, hypopharynx, orbit, parotid gland and/or extensive soft tissue infiltration beyond the lateral surface of the lateral pterygoid muscle (T4), or unilateral or bilateral metastasis in cervical lymph node(s) larger than 6 cm in greatest dimension, and/or extension below the caudal border of cricoid cartilage (i.e.

Publication date: Available online 13 January 2020Source: Brazilian Journal of OtorhinolaryngologyAuthor(s): Semih Ak, Caner Kiliç, Samet ÖzlügedikAbstractIntroductionSurgical treatment options are limited for nasopharyngeal cancer for many reasons including epidemiological and histological properties, proximity to important structures, heavy lymphatic drainage, and the difficulty in ensuring a safe surgical margin; therefore primary treatment is generally radiotherapy and chemotherapy. With current radiotherapy technology, oncological success has been increased and the quality of life of patients during t...

In this study, four different weight% of Punica granatum fruit peel extract were used as green stabilizers to synthesize IONPs followed by a series of characterization experiments and in vitro anticancer evaluation. Results revealed that all synthesized IONPs have high degree of crystallinity and purity. The optimum saturation magnetization, and hydrodynamic size were found to be ∼69 emu.g−1, and 26.52 nm, respectively. Morphological studies demonstrated that adding peel extract decreased size of NPs with the average particle size below 11 nm. Cytotoxicity assay showed that the IONPs were not react...

Abstract AP-1 is a dimeric complex that is composed of JUN, FOS, ATF and MAF protein families. FOS-related antigen 1 (FRA1) which encoded by FOSL1 gene, belongs to the FOS protein family, and mainly forms an AP-1 complex with the protein of the JUN family to exert an effect. Regulation of FRA1 occurs at levels of transcription and post-translational modification, and phosphorylation is the major post-translational modification. FRA1 is mainly regulated by the mitogen-activated protein kinases signaling pathway and is degraded by ubiquitin-independent proteasomes. FRA1 can affect biological functions, such as tumor...

This study aimed to evaluate the prognostic value of combining pretreatment Epstein ‐Barr virus (EBV) DNA level and cervical node necrosis (CNN) for patients with nasopharyngeal carcinoma (NPC) receiving intensity‐modulated radiotherapy (IMRT). A total of 607 incident nonmetastatic NPC patients treated with IMRT ± chemotherapy were reviewed. Patients were divided into four g roups based on EBV DNA level and CNN status. The primary endpoint was progression‐free survival (PFS). Kaplan‐Meier curves with log‐rank test were applied to compare survival outcomes and the Cox proportional model was used t...

Conclusion: These results suggest that apatinib might be effective for not only gastric cancer but also other carcinomas including lung cancer, colorectal cancer, cervical cancer, liver cancer, breast cancer, and nasopharyngeal cancer. Thus, apatinib is a promising targeted drug for multiple types of cancer.

Authors: Yao Z, Zhang Y, Xu D, Zhou X, Peng P, Pan Z, Xiao N, Yao J, Li Z Abstract d_abstr_R Long non-coding RNAs (lncRNAs), a group of non-protein-coding RNAs longer than 200 nucleotides, are involved in multiple biological and pathological processes, such as proliferation, apoptosis, migration, invasion, angiogenesis, and immune escape. Many studies have shown that lncRNAs participate in the complex network of cancer and play vital roles as oncogenes or tumor-suppressor genes in a variety of cancers. Moreover, recent research has shown that abnormal expression of lncRNAs in malignant tumor cells before and after ...
