EGFR overexpression is not common in patients with head and neck cancer. Cell lines are not representative for the clinical situation in this indication.

Conclusions: Cell lines are not representative of the clinical situation in HNSCC. Larger studies should investigate whether patient subgroups with activating EGFR mutations or overexpression can be identified. PMID: 29989001 [PubMed]

Targeting the PPIs formed between RPA and other DNA Damage Response (DDR) mediators has become an intriguing area of research for cancer drug discovery. A number of studies applied different methods ranging from high throughput screening approaches to fragment-based drug design tools to discover RPA inhibitors. Although these method...

We previously proposed a detailed computational model for this network, which consists of four coupled Cdk modules. Both this detailed model and a reduced, skeleton version show that the Cdk network is capable of temporal self-organization in the form of sustained Cdk oscillations, which correspond to the orderly pr...

Kibel, Annemarie Uhlig, Quoc-Dien TrinhIntroductionWith improvements in early detection and treatment, a growing proportion of the population now lives with a personal history of a cancer. Although many cancer survivors are in excellent health, the underlying risk factors and side effects of cancer treatment increase the risk of medic...

ConclusionPD-1/PD-L1 pathway was expressed in MTC patients and was significantly correlated with the distant metastases at surgery, which may shed light on PD-1/PD-L1 as a promising therapeutic target in MTC. Future better understanding of PD-1/PD-L1 expression and their relationship with immunotherapy response may provide direct evidence for management of refractory MTC.

Authors: Buchanan T, Mutch D Abstract INTRODUCTION: Although a relatively uncommon disease, the treatment of vulvar cancer has changed considerably over the years and has been under considerable focus due to its past overtreatment and apparent increase in incidence. The purpose of this review is to describe the recommended management of the most commonly encountered vulvar carcinomas based on the most recent available literature. Areas covered: The clinical environment of squamous cell vulvar cancers are illustrated in order to describe the potential pitfalls and limitations of treatment. Then, by examining publish...

Authors: Arunkumar G, Deva Magendhra Rao AK, Manikandan M, Prasanna Srinivasa Rao H, Subbiah S, Ilangovan R, Murugan AK, Munirajan AK Abstract MicroRNAs (miRNAs) are reported to function as a major component in the cellular signaling circuit, which regulates epithelial-mesenchymal transition (EMT). Dysregulation of the microRNA-200 (miR-200) family and EMT-associated genes enables tumor metastasis and resistance to therapy. The present study profiled miR-200 family members miR-200a, miR-200b, miR-200c, miR-141 and miR-429, and also several EMT-regulatory genes including zinc finger E-box-binding homeobox (ZEB)1, ZE...

CONCLUSION: In conclusion, men diagnosed with HNSCC, those with higher grade or advanced state tumor, and those treated by surgery alone are at higher risk of unfavorable outcomes than others and may need more frequent follow-up visits. PMID: 28846014 [PubMed - in process]

Conclusion EBV radiosensitized the p53 mutant tobacco associated head and neck cell line, FaDu. Objectives In the head and neck, HPV is a major risk factor associated with tonsil and base of tongue cancers, while a majority of undifferentiated nasopharyngeal cancers are positive for EBV. Clinically, head and neck tumors positive for HPV or EBV are more radiosensitive than tumors associated with tobacco and alcohol. This study aimed to evaluate whether viral infections can sensitize tobacco-associated head and neck squamous cell carcinoma cell line that harbors multiple mutations, especially TP53, to radiotherapy. Method Fo...

Human papillomavirus-associated oropharyngeal squamous cell carcinoma is now recognised as a subtype of head and neck cancer with distinct clinical, molecular and histological characteristics. The majority of these carcinomas are of non-keratinising squamous type but there is a growing number of histomorphologic variants of this disease. Here we describe the clinical, histomorphologic and immunophenotypic features of two cases of human papillomavirus-associated oropharyngeal squamous cell carcinoma demonstrating a clearly delineated biphasic differentiated and undifferentiated phenotype.
