ASCO GI: Phase III Bevacizumab Results of the AVEX and TRIBE Trials

The same week that bevacizumab (Avastin) received a new indication for the treatment of metastatic colorectal cancer, results from two phase III trials involving the drug were presented at the American Society of Clinical Oncology 2013 Gastrointestinal Cancers Symposium (ASCO GI) held January 24–26 in San Francisco.

Authors: Ren C, Zhang Z, Wang S, Zhu W, Zheng P, Wang W Abstract Metastasis is the main cause of increasing cancer morbidity and mortality. However, the underlying mechanism of cancer metastasis remains largely unknown. In the present study, we identified one circular RNA (circRNA) closely related to the metastasis of colorectal cancer (CRC), namely hsa_circ_0001178. CRC patients with high hsa_circ_0001178 were more prone to have metastatic clinical features, advanced TNM stage and adverse prognosis. Stable knockdown of hsa_circ_0001178 significantly weakened CRC cell migratory and invasive capabilities in vitro as...

ConclusionsNetwork pharmacology analysis revealed that the compounds isoquercitrin, quercitrin, berberine, chlorogenic acid and caffeic acid showed strong synergistic interactions with the cancer-related targets and pathways. It could be concluded that N. domestica Thunb. constituents affect both apoptosis and Akt-signaling pathways during the stages of early and intermediate adenoma through interaction with the targets CASP3 and MAPK1 (ErC2) while during the stages of late adenoma and carcinoma, the compounds acts through the p53 and ErbB signaling pathways.Graphical abstract

Authors: Pakdemirli A, Karaca C, Sever T, Daşkin E, Leblebici A, Yiğitbaşi T, Başbinar Y Abstract Natural products are a popular insight for researchers to investigate promising anti-cancer agents since some of these substances have lesser adverse effects restricting the treatment than traditional chemotherapeutic agents. A well-known monoterpene Carvacrol, widely consumed in Mediterranean cuisine and related to lower risks of cancer, has efficient anti-cancer effects. However, the mechanism of action is yet to be discovered. So this study aims to illuminate a new perceptive in the role of this substance on col...

Reprogrammed glucose metabolism and increased glycolysis have been implicated in tumor chemoresistance. The aim was to investigate the distinct roles of the glucose metabolites pyruvate and ATP in chemoresistance mechanisms, including cell death and proliferation. Our data showed higher glucose transporters in colorectal cancer (CRC) from non-responsive patients than those responsive to chemotherapy. Human CRC cell lines exposed to 5-fluorouracil (5-FU) displayed elevated cell viability and larger tumors in xenograft mouse models if cultured in high-glucose medium. Glucose conferred resistance to 5-FU-induced necroptosis v...

Conclusions: ctDNA shows enormous promise as a sensitive biomarker for monitoring response to many treatment modalities and for targeting therapy. Thus, it is emerging as a new way for guiding treatment decisions—initiating, altering, and ceasing treatments, or prompting investigation into the potential for residual disease. However, many potentially useful ctDNA markers are available and more work is needed to determine which are best suited for specific purposes and for improving specific outcomes.

ConclusionPreoperative immunonutrition was found to reduce both postoperative situs site infections and need of antibiotic treatment during the postoperative course. This study encourages the use of preoperative immune-enhancing nutrition as a part of multimodal prehabilitation programs in the management of frail colorectal cancer patients.

Conclusions: The patients demonstrated a high level of safety, efficacy, and satisfaction with the ileal-vaginal extension for treating vaginal stump contracture after cervical cancer surgery combined with radiotherapy, suggesting that this method is valid for broad clinical application to improve the life quality of cervical cancer patients after surgery.
