The emerging role of noncoding RNAs in colorectal cancer chemoresistance

ConclusionsIn this review, we highlight the emerging roles and the regulatory mechanisms by which miRNAs and lncRNAs affect CRC chemoresistance. Tumor-specific miRNAs and lncRNAs may serve as novel therapeutic targets and prognostic biomarkers for CRC.

AbstractPurposePreoperative short-course radiotherapy (PSRT) and preoperative long-course radiotherapy (PLRT) are standard treatment regimens for locally advanced rectal cancer. However, whether the efficacy and safety of PSRT with delayed surgery (more than 4  weeks) are superior to those of PLRT remains unresolved and was explored in this meta-analysis.MethodsStudies published in PubMed, Embase, the Cochrane Library, databases were systematically searched. RevMan 5.3 was used to calculate pooled hazard ratios (HR) and relative risk (RR).ResultsSeven studies including 4973 patients were identifi...

ConclusionAlthough classically, majority of studies have shown oncogenic roles of nucleoporins as genetic fusion partners in several types of leukemia, emerging evidence suggests that nucleoporins also modulate many cellular signaling pathways that are associated with several major non-hematological malignancies, such as carcinomas of skin, breast, lung, prostate and colon. Hence, nucleoporins are emerging as novel therapeutic targets in human tumors.

ConclusionsOnly 3 out of 612 non-silent mutations encoded for neoantigens that were detectable by MS. Although MS has sensitivity limits and biases, and likely underestimated the true neoantigen burden, this established a lower bound of the percentage of non-silent mutations that encode for presented neoantigens, which may be as low as 0.5%. This could be a reason for the poor responses of non-hypermutated CRCs to immune checkpoint inhibitors. MEK-inhibitors recently failed to improve checkpoint-inhibitor efficacy in CRC and the observed lack of HLA upregulation or improved peptide presentation may explain this.

Authors: Grothey A, Marshall JL, Bekaii-Saab T Abstract The standard treatment for patients with metastatic colorectal cancer (mCRC) in the first- and second-line setting is generally chemotherapy, which can be augmented with vascular endothelial growth factor-targeted therapies and, for patients with KRAS wild-type status, epidermal growth factor receptor-targeted therapies. However, nearly all patients ultimately develop disease progression and require later lines of therapy. Traditionally, physicians recycled chemotherapy in the later lines, with many patients showing diminished or no response. However, the past...

AbstractBackgroundWithin the context of metastatic colorectal cancer, patients with Eastern Cooperative Oncology Group (ECOG) performance score 0 –1 are usually pooled together in clinical practice guidelines and clinical trials’ reports. The current study aims to delineate potential differences in outcomes between metastatic colorectal cancer patients with ECOG score 0 versus 1 who are treated with currently accepted first-line fluoroura cil (5FU)-based chemotherapy.MethodsThe current study is based on a pooled dataset from five clinical trials of 5FU-based treatment for metastatic colorectal cancer (NCT002720...

CONCLUSION: Surgical oncologists consider the patient's condition and postoperative course rather than high-risk factors to determine use of AC. Regardless of AC use, both the extent of surgery and the patient's subsequent status affected the survival rate in the high-risk group. None of the factors identified influenced survival rate in the low-risk group. PMID: 31726001 [PubMed]
