Abstract Background Adding anti-epidermal growth factor receptor (anti-EGFR) target agents to conversion therapy may improve the resection rates and survival of patients with potentially resectable metastatic colorectal cancer (mCRC). This study aims to analyze the efficacy and safety of additional anti-EGFR target agents. Methods A systematic search was conducted on PubMed, Web of Science, Embase, and Cochrane Library. And all relevant studies published in English before January 2023 were collected to explore the impact of additional anti-EGFR targeted agent on the efficacy and safety of patients with potentially resectable mCRC (PROSPERO: CRD42022340523, https://www.crd.york.ac.uk/PROSPERO/ ). Results This study included a total of 8 articles, including 2618 patients. The overall response rate (ORR) and R0 resection rates of the experimental group were higher than those of the control group, while there was no significant difference in progression-free survival (PFS) and overall survival (OS) between the two groups. In RAS/KRAS wild-type patients, the ORR ( RR : 1.20, 95% Cl : 1.02–1.41, p = 0.03), R0 resection rate ( RR : 1.60, 95% Cl : 1.17–2.20, p = 0.003), PFS ( HR : 0.80, 95% Cl : 0.68–0.93, p = 0.003), and OS ( HR : 0.87, 95% Cl : 0.76–0.99, p = 0.031) of the experimental group were higher than those of the control group. While in KRAS mutant patients, there was no statistical difference between the two groups in ORR, R0 resection rate, PFS, and OS. Conclusion The addition of anti-EGFR targeted agents can improve the prognosis of RAS/KRAS wild-type patients with potentially resectable mCRC, while KRAS mutant patients may not benefit. In addition, the overall safety factor was controllable.
Introduction: The purpose of this meta-analysis is to evaluate the efficacy and safety of cyclin-dependent kinase4/6 inhibitors (CDK4/6i) combined with endocrine therapy (ET) on hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2–) breast cancer (BC). Material and methods: A search was conducted in the PubMed, Embase, Web of Science, and Cochrane Library databases before July 2022. Results: A total of 19 studies comprising 19,004 patients were eligible for this meta-analysis. This meta-analysis found that for unresectable locally advanced or metastatic HR+, HER2– BC, CDK4/6i combined with ET can significantly improve the progression-free survival (PFS) (hazard ratio = 0.59, p < 0.001), overall survival (OS) (hazard ratio = 0.77, p < 0.001), objective response rate (ORR) [risk ratio (RR) = 1.32, p = 0.001)], disease control rate (DCR) (RR = 1.10, p < 0.001), and clinical benefit response (CBR) (RR = 1.15, p = 0.001). For early HR+, HER2- BC, CDK4/6i combined with ET improved ORR (RR = 1.14, p = 0.05) and invasive disease free survival (iDFS) (hazard ratio = 0.87, p = 0.045) but had no effect on pathologic complete response (pCR) (RR = 1.75, p = 0.33), distant recurrence free survival (DRFS) (hazard ratio = 0.83, p = 0.311), and OS (hazard ratio = 1.08, p = 0.705). Conclusion: CDK4/6i combined with ET can improve the prognosis of patients with unresectable locally advanced or metastatic HR+, HER2– BC, but it has no obvious effect on patients with early HR+, HER2– BC. It is generally safe and manageable.
This study aimed to investigate the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of patients with pyrrolidine alkaloids-induced hepatic sinusoidal obstruction syndrome (PA-HSOS).Patients diagnosed with PA-HSOS and treated in Ningbo No.2 Hospital between November 2017 and October 2022 were enlisted in this retrospective cohort study.This cohort comprised a total of 22 patients with PA-HSOS, of which 12 patients received TIPS treatment and 10 patients experienced conservative treatment. The median follow-up duration was 10.5 months. Baseline characteristics existed with no significant difference between the two groups. No operation failures or any TIPS-associated intraoperative complications were observed after TIPS. In the TIPS group, the portal venous pressure was substantially decreased from 25.3 ± 6.3 mmHg to 14.4 ± 3.5 mmHg after TIPS ( P = 0.002). Compared with preoperative, the ascites after TIPS were significantly subsided ( P = 0.001) and there existed a considerable decrease in Child-Pugh score. At the end of follow-up, 5 patients died, involving 1 in the TIPS group and 4 in the conservative treatment group. The median survival time was 13 (3-28) months in the TIPS group and 6.5 (1-49) months in the conservative treatment group, respectively. The survival analysis demonstrated that the total survival time of TIPS group was longer than that of the conservative treatment group, no statistical significance was observed ( P = 0.08).TIPS may be a secure and effective therapeutic strategy for PA-HSOS patients who do not respond to conservative treatment.
Metformin is one of the most common drugs for type 2 diabetes mellitus (T2DM) treatment. In addition, metformin intends to have a positive effect on the prognosis of several cancers. However, the therapeutic effect of metformin on gastric cancer (GC) remains controversial. This study explores and updates the therapeutic effect of metformin in GC patients with T2DM.We searched through PubMed, Embase, Web of Science, and the Cochrane Library for relevant articles by July 2022. The relationship between metformin therapy and the prognosis of GC patients with T2DM was evaluated based on the hazard ratio (HR) at a 95% confidence interval (95% CI). Overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS) were the primary outcomes analyzed.Seven retrospective cohort studies with a combined 2,858 patients met the inclusion criteria. OS and CSS were reported in six studies, and PFS was reported in four studies. Pooled results showed that, compared to the nonmetformin group, the prolonged OS (HR = 0.72, p = 0.001), CSS (HR = 0.81, p = 0.001), and PFS (HR = 0.70, p = 0.008) of the experimental group may be associated with the exposure to metformin.Metformin may have a beneficial effect on the prognosis of GC patients with T2DM.
