The present review summarizes the current clinical data, highlighting the role of sintilimab in treating various types of cancer, including non-small cell lung cancer, liver cancer, gastric cancer and neuroendocrine tumors. The review also explores the mechanism of action of sintilimab, its structural and pharmacokinetic properties and its safety profile, which includes a comprehensive analysis of immune-related adverse events. Notably, the high binding affinity of sintilimab to PD-1 and its fully humanized nature contribute to its potent immunotherapeutic effects and favorable safety profile. Clinical trials have shown that sintilimab, either used as a monotherapy or in combination with chemotherapeutic agents, can significantly extend progression-free and overall survival in patients with advanced cancers. Furthermore, the economic implications and accessibility of sintilimab, particularly in resource-limited settings, are discussed. The current review reports on the innovative potential of sintilimab in shaping future cancer treatment strategies and emphasizes the need for personalized therapy based on individual patient biomarkers. The study reveals that sintilimab is not only a viable alternative to existing PD-1 inhibitors, but also a promising candidate for further research and development in immuno-oncology.</p>","PeriodicalId":19503,"journal":{"name":"Oncology Letters","volume":"29 5","pages":"240"},"PeriodicalIF":2.5,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12142286/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144248965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In total, 45 patients with AML who were treated between January 2015 and December 2021 were retrospectively included. A significantly longer median OS time was observed in the group receiving idarubicin [12 mg/m<sup>2</sup> intravenous (IV) on days 1-3] and cytarabine (100 mg/m<sup>2</sup> continuous IV infusion on days 1-7) (I3A7 group) (median not reached) compared with that in the venetoclax group [10.7 months; 95% confidence interval (CI), 6.3-20.8], the low-dose cytarabine (LDAC) group (4.7 months; 95% CI, 0.8-18.7) and the group receiving idarubicin (12 mg/m<sup>2</sup> IV on days 1-2) with cytarabine (100 mg/m<sup>2</sup> continuous IV infusion on days 1-5) (I2A5 group) (2.3 months; 95% CI, 0.5-2.3).

The secondary endpoint was to evaluate the impact of SIRT1 expression levels on progression-free survival (PFS). The present study was a single-center, retrospective cohort study that included patients who underwent hysterectomy between June 2017 and December 2021 and had a postoperative histopathological diagnosis of non-endometrioid EC. The tissue slides were stained with a monoclonal antibody targeting the SIRT1 protein. The nuclear staining reaction of SIRT1 was considered to be positive in the presence of any percentage of nuclear staining. The cytoplasmic staining reaction of SIRT1 was assessed using the immune reactivity scoring (IRS) system, which was determined by multiplying the scores for the staining percentage and staining intensity. IRS values of 0 to 2 were considered as negative expression; 3 to 4 as low expression; 6 to 8 as moderate expression; and 9 to 12 as high expression. Cox proportional hazards regression models were used to identify factors influencing PFS. Data from a total of 43 patients who met the eligibility criteria were presented. Cytoplasmic staining with SIRT1 was detected in all samples (100%), whereas no nuclear staining was evident in any of the tissue samples. According to the IRS results, 20.9% of samples exhibited negative cytoplasmic expression, 14.0% exhibited low expression, 37.2% exhibited moderate expression and 27.9% exhibited high expression. The estimated 3-year PFS rate was 43.6%. Cox regression models demonstrated no independent factor influencing PFS. In conclusion, SIRT1 expression was found to be cytoplasmic in non-endometrioid EC.

To evaluate the expression levels of ferroptosis genes and their association with prognosis in lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC), The Cancer Genome Atlas LUAD and LUSC data were downloaded, patient clinical information and ferroptosis gene expression profiles were extracted, and differential gene expression, survival and correlation analyses were performed using R. Using immune correlation analysis, the value of ferroptosis genes for immunotherapy was explored. The potential application of ferroptosis genes in immunotherapy was further validated by immunohistochemical staining. A number of ferroptosis-associated genes were differentially expressed in tumor tissues compared with in non-tumor tissues. CDGSH iron-sulfur domain-containing protein 1 (CISD1) was upregulated in both LUAD and LUSC tumor tissues, and was associated with tumor Tumor-Node-Metastasis stage. Notably, high levels of CISD1 in LUAD indicated a poor prognosis, and CISD1 was negatively correlated with CD4<sup>+</sup> T cells based on the immune score. Furthermore, CISD1 may be involved in pathways such as cellular response to hypoxia, DNA repair, extracellular matrix-related genes, epithelial-mesenchymal transition markers, oxidative phosphorylation and PI3K-AKT-mTOR pathway. Immunohistochemical staining indicated that CISD1 was highly expressed in LUAD tissues, it was associated with a poor prognosis of patients with LUAD, and it was negatively associated with CD4 and CD20. In conclusion, the ferroptosis gene CISD1 may be associated with the prognosis of LUAD, and high levels of CISD1 could indicate a shorter survival time. Furthermore, CISD1 has potential applications in immunotherapy.

Therefore, the present study performed a network meta-analysis to compare the prognostic and diagnostic value of the expressions of several CSC markers for patients with HCC and to identify the most efficient CSC marker. Studies on the associations of positive CSC markers with the overall survival (OS) rate, disease-free survival (DFS) rate, recurrence-free survival (RFS) rate, recurrence rate, differentiation, microvascular invasion and metastasis in patients with HCC were included in the network meta-analysis following searches on the PubMed, Embase, Elsevier and The Cochrane Library databases from January 1, 2013 to November 17, 2023. The Quality Assessment of Diagnostic Accuracy Studies-2 tool was used to assess the quality assessment of studies, and R (version 4.3.1), Stata (version 15.0) and Review Manager (version 5.3) were used for analysis. A total of 37 studies involving 3,980 participants were included. For patients with HCC, simultaneous positivity of cytokeratin 19 (CK19) and epithelial cell adhesion molecule (EpCAM) was the strongest predictor of the OS rate [surface under the cumulative ranking curve (SUCRA), 78.65%], positive keratin 19 (K19) was the strongest predictor of the RFS and DFS rates (SUCRA, 98.93 and 84.95%, respectively), and simultaneous positivity of EpCAM and cluster of differentiation (CD)90 was the strongest predictor of the recurrence rate (SUCRA, 5.61%). In addition, positivity of CD56, K19 and CD133 had the best diagnostic efficacy for poor differentiation [superiority index, 7.4498; 95% confidence interval (CI): 0.3333, 13.0000], microvascular invasion (superiority index, 8.4777; 95% CI: 0.2308, 17.0000), and metastasis (superiority index, 5.6097; 95% CI: 0.3333, 11.0000), respectively. In conclusion, no single CSC marker possessed the best predictive effect on all indexes of survival prognosis and diagnosis of patients with HCC. In terms of survival prognosis, simultaneous positivity of CK19 and EpCAM demonstrated the strongest predictive effect on the OS rate, suggesting an association with a low OS rate in patients with HCC; positive K19 revealed the strongest predictive effect on the RFS rate and DFS rate, suggesting an association with low RFS and DFS rates in patients with HCC; and simultaneous positivity of EpCAM and CD90 had the strongest predictive effect on the recurrence rate, suggesting a high recurrence rate in patients with HCC patients. In terms of diagnostic value, CD56, K19 and CD133 were the strongest predictors of poor differentiation, microvascular invasion and metastasis, respectively.
