'Urgent suspicion of cancer' referrals to a head and neck clinic - what do patients expect?

CONCLUSION: Patients with non-cancer symptoms are frequently referred with suspected cancer. Patients with red flag symptoms are not aware of their significance and they have low expectations of healthcare. PMID: 31439066 [PubMed - as supplied by publisher]

JohnsonAbstractEpidemiologic evidence indicates that regular use of nonsteroidal anti-inflammatory drugs (NSAIDs) provides a protective effect against the development of colorectal, breast, and head and neck cancers. Genomic characterization of these cancers has lent considerable insight into the subpopulations of cancer patients who are most likely to benefit from NSAID therapy. The PIK3CA gene encodes the catalytic subunit of phosphatidylinositol 3-kinase (PI3K) and...

Authors: Xu Z, Zheng X, Zheng J Abstract Salivary adenoid cystic carcinoma (SACC) is a rare head and neck malignancy characterized by unpredictable expansion, considerable perineural invasion and high risk of metastasis; however, the underlying mechanism of SACC progression remains unclear. Cancer-associated fibroblasts localized within the tumor microenvironment may promote cancer malignant transformation by enhancing tumor growth, blood vessel formation, inflammation development and metastasis occurrence. Small extracellular vesicles, including exosomes, are mediators of intercellular communication and can influe...

This study investigates the performance of label-free, reflectance-based hyperspectral imaging (HSI) and autofluorescence imaging for SCC detection at the cancer margin in excised tissue specimens from 102 patients and uses fluorescent dyes for comparison. Fresh surgical specimens (n = 293) were collected during H and N SCC resections (n = 102). The tissue specimens were imaged with reflectance-based HSI and autofluorescence imaging and afterwards with two fluorescent dyes for comparison. A histopathological ground truth was made. Deep learning tools were developed to detect SCC with new patient samples (inter-patient) and...

In this study, we overexpressed LMP1 in two NPC cell lines and found elevated level of cytokeratin 19 (CK19) expression. CK19 is an undifferentiated keratin and a stem cell marker. We also have found an increased number of ALDH positive cells along with LMP1 overexpression in both cell lines. Our data demonstrate that LMP1 regulates the maintenance of ALDH-1 positive NPC cancer stem cells, thus shedding light on target therapy of NPC in clinical application. Keywords: nasopharyngeal carcinoma; latent membrane protein 1; aldehyde dehydrogenase; cancer stem cells. PMID: 31507199 [PubMed - in process]

LuoAbstractTo compare the effectiveness and safety of robotic surgery with that of open operations for patients with cancers of the head and neck we made an electronic search of the CENTRAL, MEDLINE, EMBASE, CNKI, CBM, Opengray and Sciencepaper Online databases, and then made a manual search of specific online databases and the reference lists of relevant papers. Our most recent searches were made on 18 July 2018, and we included randomised control...

Conclusion: We found few genetically-related as well as identical isolates among the 32 Candida strains which indicated low cross-contaminations among the patients. There was no relationship between C. albicans MLST profiles and their geographic distribution, cancer type and SAP2 gene expression. This lack of correlation was possibly due to the small understudy population; hence, finding more relevance requires studies with a higher number of samples.

In this study, we evaluated the inhibitory effects of OPZ on lung cancer cell lines in vitro. The results showed that OPZ significantly suppressed cell proliferation and strongly induced apoptosis in both tested lung cancer cells independent of p53 expression. OPZ was able to cause obvious caspase 3 and PARP cleavages and stabilize p53 and its transcriptional targets p21, PUMA, and Noxa. Moreover, OPZ was capable of sensitizing lung cancer cells to the conventional chemotherapeutic drug cisplatin. Our study provides preclinical data and sheds light on the potential applications of proteasome inhibitor OPZ in lung cancer tr...
