Sintilimab is a recombinant fully human anti-programmed death 1 (PD-1) monoclonal antibody that blocks the interaction of PD-1 with its ligand. We evaluated the safety and efficacy of sintilimab combined with chemotherapy and targeted therapy in the treatment of advanced malignant tumors.
We performed a retrospective analysis of the clinical data of patients with advanced malignant tumors treated with sintilimab combined with chemotherapy and targeted therapy admitted to the Third Ward of the Department of Medical Oncology, First Affiliated Hospital of Anhui Medical University, China, from July 2019 to February 2021. The objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and related adverse reactions were analyzed.
A total of 48 patients with advanced malignant tumors treated with sintilimab combined with chemotherapy and targeted therapy. All 48 patients completed 2 courses of treatment, and the ORR and DCR were 20.83% and 81.25%. The mediaced malignant tumors, with increases in the treatment efficacy and DCR for advanced tumors. Because of few adverse reactions and proven efficacy, sintilimab combination therapy can be used as an option for the treatment of advanced malignant tumors.
Circular RNAs (circRNAs) have been confirmed to exert important roles in promoting tumor initiation and progression. However, the expression, effect, and underlying mechanism of circTADA2A in non-small cell lung cancer (NSCLC) remain unclear.
A total of 60 paired clinical samples of NSCLC tissues and corresponding normal adjacent tissues were obtained. Quantitative real-time PCR was used to verify circTADA2A, miR-450b-3p, and HMGN5 mRNA expression. The NSCLC cell Lines A549 and H1299 were individually transfected with circTADA2A and HMGN5. The regulatory interaction between circTADA2A and miR-450b-3p was investigated by dual-luciferase reporter assay. HMGN5 protein expression was detected by Western blotting.
CircTADA2A expression was significantly upregulated and correlated with poor overall survival of NSCLC patients. Functionally, circTADA2A inhibition successfully suppressed the proliferation, invasion, and migration of A549 and H1299 cells. circTADA2A functioned as a competing endogenous RNA to sponge miR-450b-3p to promote the expression of HMGN5 mRNA and protein. Furthermore, a positive relationship between circTADA2A and HMGN5 existed in NSCLC tissues. There were negative relationships between circTADA2A and miR-450b-3p as well as miR-450b-3p and HMGN5 in NSCLC tissues.
These findings suggest that circTADA2A might act as an oncogenic circRNA that promotes NSCLC progression by sponging miR-450b-3p and promoting HMGN5 expression, indicating that the suppression of circTADA2A could become a potential therapeutic target for restraining NSCLC.

Lung cancer is one of the most common malignant tumors in the world, of which the rate of incidence has continuously increased over recent years. Lung adenocarcinoma (LUAD) is the most frequent pathological type of lung cancer.
In order to discover the key markers for the occurrence and development of LUAD, we collected messenger RNA (mRNA) expression datasets in the Gene Expression Omnibus (GEO), namely, GSE2514, GSE7670, and GSE40275. The differentially expressed genes (DEGs) were screened using the online interface between GEO and R (GEO2R). Then, DEGs were functionally annotated in the Database for Annotation, Visualization, and Integrated Discovery (DAVID). Next, a protein-protein interaction (PPI) network was drawn by using the Search Tool for the Retrieval of Interacting Genes (STRING) web tool and Cytoscape software. Finally, Kaplan-Meier plotter was utilized to analyze the overall survival (OS) of the hub genes. The correlation between fibroblast growth factor 2 (
) and immune infiltration was s to be involved in the immune microenvironment of LUAD.
Esophageal cancer (EC) is highly malignant, with poor prognosis. The main forms of treatment are surgery, radiotherapy, and chemotherapy. In recent years, the incidence and mortality rate of patients with EC has improved. However, the factors that affect the quality of life of EC patients are unclear. This study investigated the postoperative complications and quality of life of EC patients, and identified the related factors. The relationship between complications and quality of life was explored so as to provide guidance for the clinical treatment and rehabilitation these patients.
A total of 120 patients with EC who underwent surgery at the First People's Hospital of Lianyungang from January 2016 to August 2017 were retrospectively enrolled in this study. The patient's subjective quality of life evaluation was documented and clinical data were collated. The correlation between the incidence of postoperative complications and the patient's quality of life, serum tumor markers, and prognosis was analyzedmplications have poorer quality of life and obvious symptoms of fatigue, pain, and swallowing pain. Health education and dietary guidance should be provided to such patients to improve their symptoms.
EC is a common malignant tumor with a high incidence of postoperative complications. Patients with high CYFRA21-1 expression should be aware of the higher risk of postoperative complications. Patients with complications have poorer quality of life and obvious symptoms of fatigue, pain, and swallowing pain. Health education and dietary guidance should be provided to such patients to improve their symptoms.
The ubiquitin-proteasome pathway (UPP) plays a key role in the intracellular degradation of abnormal and misfolded proteins in eukaryotic cells. Multiple myeloma (MM) is a common hematologic malignancy caused by clonal expansion of malignant plasma cells. Proteasome-targeted drugs such as carfilzomib, which is a selective proteasome inhibitor (PI), could play an important role in the treatment of diseases such as MM.
MM cells were treated with different concentrations of carfilzomib and apoptosis as well as the viability of MM cells were measured by flow cytometry analysis and MTT assay. We also measured the effect of carfilzomib on the proliferation of myeloma cells by DNA incorporation of the pyrimidine analog BrdU. The effect of carfilzomib on apoptosis was detected by immunofluorescence TUNEL staining and western blot. We also verified its effect on the STAT1/COX-2/iNOS pathway by western blot.
Carfilzomib inhibited the growth of MM cells in a concentration-dependent manner, with the strongest inhibptosis.
Cancer patients with
or
mutations may be excellent candidates for immune checkpoint inhibitors (ICIs) therapy and have favorable prognosis, but their potential in stomach adenocarcinoma (STAD) remains unknown. Therefore, the clinical significance of
and
mutations in STAD was evaluated.
A summary of
/
mutations and clinical characteristics was performed on all 613 STAD samples, from which 360 samples were screened for analysis of the potential clinical relevance of
/
mutations to prognosis and immunotherapy.
The total frequency of both
and
mutations was 7.99% in STAD patients, correlating with an older age of onset and more frequently in the antrum anatomic subdivisions. Several genes that related to prognosis and immunotherapy also had high mutation frequencies in
/
-mutant STADs. Furthermore, the STAD subgroup with
/
mutations had longer progression free survival (PFS) and overall survival (OS) in the subpopulation under 80. More importantly, STAD patients with
/
mutations exhibited adaptive immune resistance tumor microenvironment (TME) and deficient mismatch repair (dMMR) status, and possessed significantly higher PD-L1 expression level, higher tumor mutational load (TMB), higher microsatellite instability (MSI) percentage, and lower aneuploidy score, all of which may have potential implications for better ICIs treatment outcomes.
and
mutations are promising useful biomarkers to improve the clinical efficiency of practicing precision medicine in STAD patients, including as positive prognostic markers and predictive biomarkers of immunotherapy outcomes for STAD patients.
POLE and POLD1 mutations are promising useful biomarkers to improve the clinical efficiency of practicing precision medicine in STAD patients, including as positive prognostic markers and predictive biomarkers of immunotherapy outcomes for STAD patients.
Triple-negative breast cancer (TNBC) is a highly aggressive subtype and only some of patients could benefit from the immunotherapy. The present study aims to investigate the expression pattern and prognostic value of immune checkpoint genes (ICGs) in TNBC and develop a novel ICGs-signature to predict the prognosis and immune status in TNBC.
ICGs expression profiles and clinical characteristics of TNBC samples were obtained from The Cancer Genome Atlas (TCGA) and the Molecular Taxonomy of Breast Cancer International Consortium (METABRIC) database. learn more The least absolute shrinkage and selection operator (LASSO) Cox regression analysis was employed to construct a multi-gene signature for predicting the prognostic outcome. The risk scores were calculated based on the coefficients of each ICG in LASSO-Cox regression model. The median score was considered as the cut-off value to divide the TNBC patients into a high-risk group and a low-risk group. The Kaplan-Meier survival curves were generated to further explore tential indicator reflecting immunotherapy response.
A novel ICGs-signature was developed and validated, which may be not only served as a robust prognostic marker, but also a potential indicator reflecting immunotherapy response.
The liver is the most common site for rectal cancer metastasis, and liver resection combined with chemotherapy is the only treatment offering the possibility of long-term survival in patients with metastatic rectal cancer. However, a significant proportion of liver metastases cannot be surgically removed, and very limited data are available regarding the survival outcomes of these patients. This study aimed to investigate the survival pattern of rectal cancer patients with unresectable liver metastases after both chemoradiotherapy and primary tumor resection.
A total of 51,178 rectal cancer patients were identified from the Surveillance, Epidemiology, and End Results (SEER) database, of whom 448 had synchronous liver metastases and underwent both chemoradiotherapy and primary tumor resection. According to different treatment modalities, patients were divided into a hepatic resectable group and an unresectable group. The Kaplan-Meier method was used to estimate patient survival, and differences between the hepatic resectable and unresectable groups were compared using the log-rank test.
