Serum microRNA-18a and/or microRNA-21 might serve as non-invasive diagnostic markers in colorectal cancer, while serum microRNA-92a is better to be combined with either microRNA-18a or microRNA-21 as it has limited usefulness when used as sole diagnostic marker.

The link between the pro-inflammatory status, tumor aggressiveness and treatment response has been well established in multiple cancers. Various hematologic and biochemical variables representing surrogates for inflammation have been used as predictive markers. Our primary aim was to assess the prognostic value of neutrophil-to-lymphocyte ratio (NLR) in evaluating neoadjuvant treatment response in locally advanced rectal cancer (LARC).

We included 60 consecutive patients with LARC, admitted for surgery, after completing a standard full-course neoadjuvant radio-chemotherapy regimen. NLR and other hematologic parameters were collected one day prior to surgery. Treatment response was assessed on the resection specimens.

On univariate analysis, poor responders had a significantly higher NLR value when compared with good responders 5.81 (5.40-7.28) vs. 3.51 (2.36-4.04), p<0.0001. NLR retained its significance on multivariate analysis, with an OR of 3.51 (1.54-6.57), p=0.001. A NLR cut-off value of 4.50 had the best predictive value for poor response, with an area under the curve (AUC) of 0.85, sensitivity of 83.3% and specificity of 83.3% (p<0.001). Other hematologic ratios, such as the derived NLR (dNLR) and platelet-to-lymphocyte ratio (PLR) were also significant predictors for poor response, although to a lesser extent when compared to NLR.

NLR is a simple and cost-effective predictor for neoadjuvant treatment response in LARC. As more data is generated, clear cut-off values could provide valuable insight regarding the management of LARC.

To explore the associations of computed tomography (CT) features with tumor-node-metastasis (TNM) stage and pathology of patients with rectal cancer and their significance in the evaluation of efficacy and prognosis.

A total of 83 rectal cancer patients who were operated in our hospital were collected. CT examination was performed before operation, and pathological examination was conducted after operation. The influence of CT stage on the prognosis of patients with rectal cancer was assessed.

Postoperative pathological examination showed that there were 15 cases in T1-T2, 41 cases in T3 and 27 cases in T4. The results of CT examination showed that there were 15 cases in T1-T2, 40 cases in T3 and 28 cases in T4, and the sensitivity was 93.18%. It can be seen that the results in the two examinations were similar. The postoperative pathological examination revealed that lymph node metastasis occurred in 57 cases, and the main metastatic sites were the left and right pelvic cavity, near the intestine and ide metastasis. CT scan also has great value for distant metastasis, and contributes to the development of clinical therapeutic regimens for patients with rectal cancer in different stages. CT stage has an influence on the prognosis and patient survival.

Expression of programmed death ligand-1 (PD-L1) is related to the prognosis of many solid tumors, but the prognostic value of PD-L1 expression in colorectal cancer (CRC) remains unclear. The aim of this study was to clarify the role of PD-L1 expression in predicting prognosis, and then provide further insight into the relation between PD-L1 and toll like receptor-4 (TLR-4) in CRC progression.

The expression of PD-L1 and TLR-4 in patients with resected CRC was analyzed using immunohistochemistry (IHC). The biological relation of PD-L1 and TLR-4 in CRC was explored using gene set enrichment analysis (GSEA).

Positive PD-L1 and TLR-4 expression in tumor cells were observed in 12.7% and 41.2% respectively. High PD-L1 and TLR-4 expression levels were significantly correlated with poor disease-free survival. Selleck Oligomycin A PD-L1 expression was closely associated with TLR-4 expression. Multivariate analyses further confirmed that increased expression levels of PD-L1 are unfavorable prognostic factors for operable CRC.

High PD-L1 expression can be used as a prognostic indicator for patients with operable CRC. PD-L1 expression is associated with TLR-4 expression, thereby providing a theoretical basis for the combined use of PD-1/PD-L1 inhibitors and TLR agonists.

To explore the effectiveness of fluorouracil (FU) entrapped in dendritic cell (DC)-secreted exosomes (DC-Exos) for enhancing its anti-colon cancer effect.

DC-Exos were extracted through ultrahigh-speed centrifugation, and the FU-DC-Exos system was constructed using electroporation. Moreover, the influence of FU-DC-Exos on the viability of mouse colon cancer CT26 cells was determined in vitro using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and 4',6-diamidino-2-phenylindole (DAPI) staining, and pharmacodynamic evaluation was performed in vivo through TUNEL and hematoxylin-eosin (H&E) staining, with the CT26 tumor-bearing mouse model as the study object.

Compared with the control group, FU and DC-Exos groups exhibited a lowered proliferation rate of mouse CT26 colon cancer cells, whereas the apoptosis rate of cells in FU-DC-Exos group differed significantly from FU group. According to the wound healing assay, the migration rate of CT26 cells was reduced in FU and DC-Exos groups, and it was evidently different between FU-DC-Exos group and FU group. Moreover, in vivo experiments revealed that DC-Exos alone exhibited a trend of suppressing tumor growth, and that DC-Exos as carriers not only killed tumor cells alone, but also enhanced the anti-colon cancer effect of FU after entrapment.

Exos extracted via ultrahigh-speed centrifugation can be used for the preparation of the drug delivery system of FU-DC-Exos via electroporation, and drug-loaded Exos are able to effectively inhibit the proliferation of tumor cells and induce their apoptosis, exerting an anti-tumor effect.
