Key Molecular Events in Cervical Cancer Development.

Key Molecular Events in Cervical Cancer Development. Medicina (Kaunas). 2019 Jul 17;55(7): Authors: Balasubramaniam SD, Balakrishnan V, Oon CE, Kaur G Abstract Cervical cancer is the fourth most common cancer among women. Infection by high-risk human papillomavirus (HPV) is the main aetiology for the development of cervical cancer. Infection by high-risk human papillomavirus (HPV) and the integration of the HPV genome into the host chromosome of cervical epithelial cells are key early events in the neoplastic progression of cervical lesions. The viral oncoproteins, mainly E6 and E7, are responsible for the initial changes in epithelial cells. The viral proteins inactivate two main tumour suppressor proteins, p53, and retinoblastoma (pRb). Inactivation of these host proteins disrupts both the DNA repair mechanisms and apoptosis, leading to rapid cell proliferation. Multiple genes involved in DNA repair, cell proliferation, growth factor activity, angiogenesis, as well as mitogenesis genes become highly expressed in cervical intraepithelial neoplasia (CIN) and cancer. This genomic instability encourages HPV-infected cells to progress towards invasive carcinoma. The key molecular events involved in cervical carcinogenesis will be discussed in this review.

AbstractBackgroundPrevious studies have identified that patients withEGFR mutations tend to have better responses to targeted therapy, as well as chemotherapy; however, the effect of genetic alterations in terms of radiotherapy (RT) ‐related outcomes has not been fully assessed. We studied the impact of common non‐small cell lung cancer (NSCLC) genetic alterations (EGFR,ALK andKRAS) in relation to objective response rate (ORR) to RT in patients with brain metastases.MethodsFrom 2009 –2015, 153 patients with an available genotyping status were treated with whole‐brain irradiation (WBI) before receiving systemic ...

ConclusionsEndostar delivered by CIV with CCRT may be a better option than IV in terms of potential survival and safety for unresectable stage III NSCLC.Key pointsSignificant findings of the study Endostar delivered by continuous intravenous pumping might achieve more favorable survival over intravenous injection and reduce adverse hematological reactions in patients with unresectable stage III NSCLC treated with Endostar combined with CCRT.What this study adds The administration route of recombinant human endostatin is also one key factor for survival and safety to consider when treating patients with unresectable stage III NSCLC.

ConclusionsThe use of osimertinib immediately after nivolumab significantly increased the frequency of grade 3 or higher hepatotoxicity in patients with advanced NSCLC harboringEGFR mutation acquired T790M resistance.

To gain a better understanding of the factors that govern in vivo cellular recognition, artificial glycoproteins are created as biomimetic probes to study the influence of specific glycan assemblies to biodistribution. The principle aim of this Review is to present pioneering research that has driven artificial glycoprotein ‐based targeting and subsequent adaptations with potential therapeutic applications. AbstractAkin to a cellular “fingerprint,” the glycocalyx is a glycan‐enriched cellular coating that plays a crucial role in mediating cell‐to‐cell interactions. To gain a better understanding of the ...

L-GILZ binds and inhibits nuclear factor κB nuclear translocation in undifferentiated thyroid cancer cells. J Chemother. 2020 Feb 18;:1-5 Authors: Marchetti MC, Cannarile L, Ronchetti S, Delfino DV, Riccardi C, Ayroldi E Abstract Proto-oncogene mutations and abnormal activation of mitogen-activated protein kinase (MAPK) signalling are recurrently found in thyroid cancers. Some thyroid neoplasms respond to drugs that inhibit MAPK pathway activation. Previously, we showed that pharmacological inhibition of MAPK in thyroid cancer cells inhibits cell proliferation and upregulates L-GILZ (long glucoco...

Authors: Maruta M, Miyoshi T, Matsuo N, Yamashina T, Irie K, Tsuruta M, Tsukada H, Tsuruyama M, Nagano M, Hiraki Y Abstract We administered FOLFOX (oxaliplatin (L-OHP) plus infusional 5-fluorouracil (5-FU) and leucovorin) to an hemodialysis (HD) patient with advanced gastric cancer (AGC), and investigated pharmacokinetics (PKs) and dialyzability of L-OHP. The patient was a 54-year-old Japanese man with a diagnosis of inoperable AGC. FOLFOX was instituted 3 h prior to the start of a 4 h HD period with the L-OHP and 5-FU doses reduced by 50% for the first cycle, and 30% reduced dose was administered for...

CONCLUSIONS: Despite the retrospective nature of the observations and the low number of enrolled patients, the application of MRgRT in LACC appears to be safe and feasible with a favorable toxicity profile and response rates comparable to gold standard, supporting the setup of larger prospective studies to investigate the potentialities of this new technology.

CONCLUSIONS: Cancer diagnosis should always be considered in patients with unprovoked thrombosis and, if NSCLC is diagnosed, genetic alterations should be always sought after. A possible relation between venous thromboembolism and oncogenic drivers, particularly for ALK translocations, has been hypothesized. Similarly to ALK-positive NSCLC, ROS1 rearranged disease has been associated with an increased thromboembolic risk. Further studies are needed to better evaluate this relation and to evaluate the potential benefit of a prophylactic anticoagulating treatment in this subset of patients.

CONCLUSIONS: The prevalence of HPV in HNC from this area is very low. The lineage/sublineage classification of the 3 HPV types in HNC in this area is consistent with the previous reported data of HPV lineage distribution in cervical cancer within China.
