The results of bioinformatics analysis were further successfully validated in the clinical ESCA cohort by qRT-PCR and immunohistochemistry staining.

Our study constructed and validated an m6A RNA methylation regulators-based prognostic signature. This might provide important information for developing diagnostic and therapeutic strategies.

Tools for the non-invasive assessment of colorectal cancer (CRC) prognosis have profound significance. Although plasma coagulation tests have been investigated in a variety of tumours, the prognostic value of the prothrombin time (PT) and activated partial thromboplastin time (APTT) in CRC has not been discussed. Our study objective was to explore the prognostic significance of preoperative PT and APTT in CRC patients.

A retrospective analysis of preoperative coagulation indexes including PT, PTA, INR, APTT, FIB, TT, PLT, NLR and PLR in 250 patients with CRC was performed. Kaplan-Meier and multivariate Cox regression analysis were used to demonstrate the prognostic value of these preoperative coagulation indexes.

The overall survival (OS,
<0.05) and disease-free survival (DFS,
<0.05) of CRC patients with lower PT and APTT levels were significantly prolonged. Based on univariate analysis, PT levels (
<0.001,
<0.001), PTA levels (
=0.001,
=0.001), APTT levels (
=0.001,
<0.001),fication approach for more precise clinical staging of CRC.
Elevated levels of preoperative PT and APTT were predictors of poor outcomes in CRC patients. Moreover, the combination of preoperative PT and APTT can be a new prognostic stratification approach for more precise clinical staging of CRC.
Regorafenib is an oral multikinase inhibitor approved for the therapy of previously treated metastatic colorectal carcinoma (mCRC). The aim of the present study was to analyze the outcomes of treatment with regorafenib in real-world clinical practice based on data from a national registry.

The CORECT registry, the Czech non-interventional database of patients with mCRC treated with targeted agents, searched for patients with metastatic CRC treated with regorafenib. In total, 555 evaluable patients were identified.

The median age at diagnosis was 61.7 years. All patients had disease progression on or after previous systemic treatment. Most patients were treated with an initial dose of 160 mg daily (n = 463; 83.6%). The median duration of treatment was 2.7 months (range 0.0-23.4 months). By the data cut-off date, 472 patients (85%) had completed treatment with regorafenib and were evaluable for treatment response evaluation. Partial response was reported in 13 patients (2.8%) and disease stabilization in hort exceeded that reported in randomized trials. Regorafenib is a safe and active treatment option for a subgroup of patients with mCRC who are progressing after other systemic therapies and maintain good performance status.
The aim of this study was to explore the signatures of oral microbiome associated with OSCC using a random forest (RF) model.

A total of 24 patients with OSCC were enrolled in the study. The oral microbiome was assessed in cancerous lesions and matched paracancerous tissues from each patient using 16S rRNA gene sequencing. Signatures of mucosal microbiome in OSCC were identified using a RF model.

Significant differences were found between OSCC lesions and matched paracancerous tissues with respect to the microbial profile and composition. Linear discriminant analysis effect size analyses (LEfSe) identified 15 bacteria genera associated with cancerous lesions.
and
were enriched. A classifier based on RF model identified a microbial signature comprising 12 bacteria, which was capable of distinguishing cancerous lesions and paracancerous tissues (AUC = 0.82). The network of the oral microbiome in cancerous lesions appeared to be simplified and fragmented. Functional analyses of oral microbiome showed altered functions in amino acid metabolism and increased capacity of glucose utilization in OSCC.

The identified microbial signatures may potentially be used as a biomarker for predicting OSCC or for clinical assessment of oral cancer risk.

Unresectable intrahepatic cholangiocarcinoma (ICC) has a poor prognosis. The aim of this study was to evaluate the efficacy and safety of apatinib for patients with unresectable ICC.

A total of 10 patients with unresectable ICC were enrolled for this single-center observational study between March 2, 2016, and August 27, 2019. Subjects received 500 mg apatinib on a daily basis. Tumor response was assessed by 1.1 response evaluation criteria in solid tumors. The progression-free survival (PFS) and overall survival (OS) were calculated using the Kaplan-Meier method. The drug-related adverse effects were also monitored.

Based on the follow-up computed tomography and magnetic resonance imaging after treatment, 4 (40.0%), 4 (40.0%), and 2 (20.0%) patients achieved a partial response, stable disease, and progression of the disease, respectively. The response rate and disease control rate were 40.0% and 80.0%, respectively. ZIETDFMK The median PFS was 4.5 months (95% confidence interval 3.157~5.843 months); the median OS was 6.5 months (95% confidence interval 4.744~8.256 months). Furthermore, 3-, 6-, and 9-month OS rates were 77.5%, 61.7%, and 15.0%, respectively. The most common hematologic grade 3 adverse event was neutropenia (10%); the most common nonhematologic grade 3 adverse events were hypertension (20.0%) and hand-foot syndromes (20.0%). No treatment-related grade 4 or 5 adverse events were recorded.

Apatinib revealed to have antitumour activity in unresectable ICC patients, with manageable toxicities, and thus might be used as a new treatment option for patients with unresectable ICC.
