ma G. Nikalje The work reports the facile synthesis of novel α-aminophosphonate derivatives coupled with indole-2,3-dione moieties, namely the diethyl(substituted phenyl/heteroaryl)(2-(2-oxoindolin-3-ylidene)hydrazinyl)methylphosphonates derivatives 4(a–n). One-pot three component Kabachnik-Fields reactions were used to synthesize these derivatives. The reaction was carried out at room temperature by stirring in presence of ceric ammonium nitrate (CAN) as a green catalyst. The structures of the synthesized compounds were established by spectral studies. The synthesized derivatives 4(a–n) w...

Publication date: Available online 1 August 2018Source: Reports of Practical Oncology &RadiotherapyAuthor(s): Bagher Farhood, Hadi Samadian, Mahdi Ghorbani, Seyed Salman Zakariaee, Courtney KnaupAbstractNeutron capture therapy (NCT) is a targeted radiotherapy for cancer treatment. In this method, neutrons with a spectra/specific energy (depending on the type of agent used for NCT) are captured with an agent that has a high cross-section with these neutrons. There are some agents that have been proposed in NCT including 10B, 157Gd and 33S. Among these agents, only 10B is used in clinical trials. Application of 157Gd is ...

AMP-activated protein kinase (AMPK) is a metabolic regulator that acts to limit the growth of cancer cells. AMPK is downregulated by melanoma antigens A3/6 (MAGEA3/6), which are cancer-specific proteins that enhance the activity of specific E3 ubiquitin ligases to ubiquitinate and degrade AMP-activated protein kinase α1 (AMPKα1). Here, using a bioinformatic approach, we identified a microRNA, miR-1273 g-3p, that is predicted to target the 3’ untranslated region (UTR) of MAGEA3/6. Analyzing miR-1273 g-3p expression in human colon cancer tissues, we found a reduction in miR-1273 g-3p expression correl...

We report two cases showing extreme response to vemurafenib, which could not be predicted prior to treatment commencement. Genetic testing demonstrated a resistant mechanism not previously reported in CRC or PTC patients, namely an acquired mutation of RAS. This is supported by an analysis of a large cohort of BRAF V600E-positive melanomas. Further studies are needed in order to identify predictive markers for response to vemurafenib and to explore novel strategies to overcome RAS-mediated resistance.

Conclusions“InterPreT Cancer Survival” is presented as an educational tool which engages the user through interactive features to improve the understanding of commonly reported cancer survival statistics. The tool has received positive feedback from a Cancer Research UK patient sounding board and there are further plans to incorporate more disease characteristics, e.g. stage.

CONCLUSIONS: Whole-body PET/CT and abdominal ultrasound complement each other in the staging of uveal melanoma. Benign hepatic abnormalities found using ultrasound is common. Of importance, a second asymptomatic primary malignancy associated with uveal melanoma was detected almost one in 10 patients.

AW, Horenblas S, Gietema JA, van Leeuwen FE, Schaapveld M Abstract Purpose Testicular cancer (TC) treatment increases risk of subsequent malignant neoplasms (SMNs). It is unknown whether changes in TC treatment over time have affected SMN risk. Methods Solid SMN risk was evaluated in a multicenter cohort comprising 5,848 1-year survivors treated for TC before age 50 years between 1976 and 2007. SMN incidence was compared with cancer incidence in the general population. Treatment-specific risks were assessed using multivariable regression in a case-cohort design. Results After a median follow-up of 14.1 years, 350...

Abstract A series of novel benzotriazole N-acylarylhydrazone hybrids was synthesized according fragment-based design strategy. All the synthesized compounds were evaluated for their anticancer activity against 60 human tumor cell lines by NCI (USA). Five compounds: 3d, 3e, 3f, 3o and 3q exhibited significant to potent anticancer activity at low concentrations. Compound 3q showed the most prominent broad-spectrum anticancer activity against 34 tumor cell lines, with mean growth inhibition percent of 45.80%. It exerted the highest potency against colon HT-29 cell line, with cell growth inhibition 86.86%. All leukemi...
