The optimal duration of extended endocrine therapy (ET) for women with hormone receptor-positive (HR-positive) early-stage postmenopausal breast cancer remains uncertain. This meta-analysis systematically evaluated the optimal time to prolong aromatase inhibitors ( AIs) therapy for postmenopausal early stage breast cancer who received initial endocrine therapy.

Anthracyclines are effective antineoplastic drugs; however, their use is constrained by dose-dependent cardiotoxicity. Vascular endothelial dysfunction is an early independent event in cardiovascular diseases and may precede anthracycline-induced cardiotoxicity. Brachial flow-mediated dilation (FMD) is a non-invasive technique for evaluating vascular endothelial function. We evaluated the evidence on anthracycline-induced vascular endothelial dysfunction in cancer patients and survivors using FMD. Studies measuring FMD in anthracycline-treated active cancer patients or survivors were retrieved from inception to August 2024 using PubMed, Embase, and Scopus. The primary outcome was the difference in FMD between anthracycline-treated patients and healthy controls or baseline. We performed the meta-analysis using a random-effects model and evaluated the certainty in effect estimates. Overall, 18 studies (n = 841 patients) met the inclusion criteria. Compared to the baseline, a non-significant change toward a decline in FMD was observed. However, a significant reduction in FMD was observed in anthracycline-treated patients compared to healthy controls (standardized mean difference (SMD): - 0.6082; 95% CI: - 0.8963 to - 0.3201; p < 0.0001). Subgroup analyses revealed consistent significant reductions in FMD for childhood cancers (SMD: - 0.7189; 95% CI: - 0.9903 to - 0.4476; p < 0.0001), while adult cancers showed no significant difference. No significant publication bias was detected overall for healthy control comparisons. High heterogeneity was observed in the included studies (I2 = 81.7808% versus healthy controls and I2 = 75.6876% for childhood cancers subgroup analysis). Anthracyclines induce vascular endothelial dysfunction, indicated by lower FMD in cancer patients and survivors, particularly among those with childhood cancers, who might be at risk of long-term cardiovascular complications.

The efficacy and safety of pembrolizumab in treating advanced hepatocellular carcinoma (HCC) are inconsistent across studies. This study sheds light on the efficacy and safety of pembrolizumab in advanced HCC patients.

To systematically evaluate the efficacy and safety of regimens combining new drugs (bortezomib, etc.) with chemotherapy in the treatment of plasmaoblastoid lymphoma (PBL). PubMed, Embase, Web of Science, American Society of Hematology Annual Meeting Proceedings, Cochrane Controlled Trials Center Registry, Cochrane Library, Science Citation Index, and meeting abstracts were searched for quality evaluation based on Cochrane Risk and Jadad scores and other assessment tools. Patients were divided into subgroup 1 (traditional treatment vs. no treatment) and subgroup 2 (traditional treatment vs. combination of new drugs) based on medication use, and Revman 5.4 software was applied for statistical analysis. A total of 12 papers were included, including 410 patients with PBL. Meta-analysis results: the objective remission rate (ORR) of patients in the combination of new drugs group was higher than that of the traditional treatment group [56.8% (25/44) vs. 70.2% (66/94); OR = 2.18, 95%CI 1.58-2.78, P = 0.002 < 0.05], and the progression-free survival (PFS) rate of patients in the combination of new drugs group was higher than that of the traditional treatment group. the progression survival (PFS) was better than traditional treatment group (HR = 2.22, 95%CI 1.71-2.90, P < 0.001), and the heterogeneity between the results of each study I = 95%; there was no statistically significant difference between the two groups in terms of overall survival (OS) (HR = 1.81, 95%CI 0.44-7.46, P = 0.41), and grade 3-4 adverse events (AE) (HR = 0.85, 95%CI 0.27-7.46, P = 0.002 < 0.05). 95%CI 0.27-2.71, P = 0.78) were not statistically different. The regimen combining new drugs is an effective means to improve the prognosis of PBL, with better ORR and PFS than the traditional regimen, and there is no statistically significant difference between the two adverse events. However, the small sample size of this study increases the possibility of bias and the results need to be treated with caution.

Cisplatin-induced hearing loss leads to significant neurologic, social, and behavioral impairment in children. The goal of this study is to characterize options available to prevent cisplatin-induced hearing loss and to identify gaps in the literature.

Hematological cancers are among the leading malignancies affecting women of reproductive age. Oocyte cryopreservation (OC) is routinely recommended before initiating gonadotoxic treatments. We aim to evaluate OC outcomes in women with hematological cancers undergoing chemotherapy.

Cancer therapy-induced cardiotoxicity (CTRCD) is a significant adverse effect of oncologic treatment, associated with considerable morbidity and mortality. Among CTRCD, heart failure stands out in prevalence and severity, with left ventricular dysfunction being the focus of most studies. Right ventricle (RV) may also be damaged by CTRCD, however the effects of CTRCD on RV function (RVF) have not been elucidated.

Gastric cancer, especially cancer of the gastro-esophageal junction, ranks among the first five cancers in the world with the highest mortality rates. It has poor survival rates for the advanced stages. Traditional chemotherapy, while standard, often results in significant side effects and limited efficacy. The objective of this meta-analysis and systemic review is to ascertain if pembrolizumab-based therapies for advanced gastric cancer are more effective and safer than standard chemotherapy. The focus consisted of RCTs with adults suffering from gastric carcinoma who received pembrolizumab every 3 weeks (200 mg) intra-related dose or with at least comparable chemotherapy regimen. Outcomes assessed are as follows: overall survival (OS), progression-free survival (PFS), and objective response rate (ORR). All potential sources regarding the search of outcome measures were applied: Google Scholar, Scopus, PubMed, and Cochrane library, and last search in June 2024 was carried out. Out of 568 articles screened, four RCTs comprising 2,831 patients met the inclusion criteria. Analysis indicated that pembrolizumab alone did not significantly improve OS compared to chemotherapy (HR 0.87). However, when combined with chemotherapy, pembrolizumab dramatically enhanced OS (HR 0.80) and PFS (HR 0.78). ORR was superior in the pembrolizumab plus chemotherapy group (RR 1.24), while pembrolizumab monotherapy showed no significant difference from chemotherapy alone. Safety analysis revealed a higher frequency of adverse events in the pembrolizumab-based therapy groups compared to chemotherapy. Pembrolizumab together with chemotherapy improves greater survival and higher levels of response rate in patients with severe gastric cancer, especially with high PD-L1 expression. But it has rather more adverse events, allowing patient monitoring with care.

This meta-analysis aims to evaluate the efficacy and safety of rapamycin (mTOR) inhibitors with endocrine therapy versus endocrine therapy alone in treating advanced or metastatic estrogen receptor/progesterone receptor (ER/PR) + breast cancer.

Hepatic arterial infusion chemotherapy (HAIC) exhibits synergistic anticancer effects with systemic therapy in treating hepatocellular carcinoma (HCC). The approach combining systemic therapy and HAIC is likely to establish a new survival benchmark for advanced HCC. However, related evidence is still lacking.

Metastatic and recurrent gastrointestinal stromal tumors (GISTs) present challenging clinical management. Imatinib is the standard first-line therapy, improving survival and reducing tumor burden in the neoadjuvant use, facilitating surgical intervention. This systematic review and meta-analysis assessed the efficacy of neoadjuvant imatinib in metastatic/recurrent GISTs, highlighting its potential to enhance surgical outcomes and overall patient management.

The use of immune checkpoint inhibitors has recently become a promising and innovative therapeutic option for patients suffering from advanced recurrent or metastatic cervical cancer(CC), and several studies of immunotherapy have been published or have revealed stage-by-stage results at international congresses. Nevertheless, there is a lack of meta-analyses of ICIs for advanced CC in past Meta-analysis.

Gastrointestinal perforation (GIP) is a rare and potentially fatal adverse event of antineoplastic therapy. GIP is a rare but serious complication in oncology patients, often leading to significant morbidity and mortality. In general oncology patients, the incidence of GIP ranged from 0.5 to 1.9%. A meta-analysis of six clinical trials with 4579 patients reported an incidence of 1.0%. Among mCRC patients, the incidence varied between 0.5 and 2.4%, with geographic differences-1.5% in the USA and 2.4% in Australia. For metastatic melanoma patients, the incidence of GIP ranged from 0.4 to 0.67%, with U.S. rates of 0.57% and 0.67% and a lower rate of 0.40% reported in Germany. The findings suggest that the risk of GIP varies significantly across oncology populations and treatment regimens, with higher risks noted in metastatic cancer patients undergoing therapies such as VEGF inhibitors or immune checkpoint inhibitors. These data highlight the need for careful monitoring and early intervention in high-risk populations to reduce the impact of GIP on patient outcomes. This systematic review aims to summarize the incidence of GIP in general oncology, metastatic colorectal cancer (mCRC), and metastatic melanoma (MM) populations. A literature search was conducted in Embase and Medline databases from January 1, 2011 to August 30, 2017, identifying relevant studies on GIP incidence.

The comparative efficacy and safety of programmed death-ligand 1 (PD-L1) inhibitors versus programmed death protein 1 (PD-1) inhibitors in breast cancer treatment remain inconclusive, as no head-to-head randomized controlled trials (RCTs) conducted. This study aims to evaluate the efficacy and safety of PD-1/PD-L1 inhibitors as monotherapy or in combination with chemotherapy for breast cancer. A systematic review and meta-analysis were performed using major databases and oncology conference proceedings. The primary outcomes were overall survival (OS) for advanced breast cancer and pathological complete response (PCR) rate for early breast cancer. Secondary outcomes included progression-free survival (PFS) for advanced breast cancer and incidence of adverse events (AEs). Seventeen studies met the inclusion criteria, consisting of seven RCTs on early-stage and 10 on advanced breast cancer. For advanced breast cancer, PD-1/PD-L1 inhibitors modestly improved OS compared to chemotherapy, with no significant differences between PD-1 and PD-L1 inhibitors. PD-L1 inhibitors showed greater improvement in PFS compared to PD-1 inhibitors. The likelihood of AEs of any grade was higher with PD-L1 inhibitor treatment than with PD-1 inhibitor treatment. In early breast cancer, combining PD-1/PD-L1 inhibitors with chemotherapy inducing higher PCR rates than chemotherapy alone, with PD-1 inhibitors achieving better outcomes than PD-L1 inhibitors. PD-1 inhibitors were linked to slightly higher rates of grade >2 AEs compared to PD-L1 inhibitors. The findings indicate that PD-1 inhibitors may offer advantages for advanced breast cancer due to similar OS and a lower rate of AEs. For early breast cancer, PD-1 inhibitors are recommended given their superior PCR rates.

Naïve non-muscle invasive bladder cancer (NMIBC) is commonly treated with transurethral resection (TURBT), but recurrence and progression remain concerns. This meta-analysis, the first we have conducted on this topic, compared recurrence and progression rates between patients treated with neoadjuvant Mitomycin C (MMC) and the control group (TURBT alone).

Pembrolizumab, a PD-1 inhibitor, has shown potential for treating advanced gastric and gastroesophageal junction (GEJ) cancer. This meta-analysis evaluates its efficacy and safety, alone or combined with chemotherapy, in this population.

Cancer therapy-related cardiac dysfunction (CTRCD) is a major concern for patients undergoing cardiotoxic cancer treatments. Sodium-glucose co-transporter-2 (SGLT2) inhibitors have shown cardioprotective effects in both diabetic and non-diabetic populations. However, their impact on CTRCD risk remains uncertain. This meta-analysis aimed to assess the association between SGLT2 inhibitor use and CTRCD in cancer patients receiving cardiotoxic treatments. A systematic search of PubMed, Embase, and Web of Science was conducted to identify relevant studies. Cohort studies comparing CTRCD incidence in cancer patients with and without SGLT2 inhibitor use were included. Risk ratios (RRs) were pooled using a random-effects model, and subgroup and meta-regression analyses were performed to explore potential effect modifiers. Ten cohort studies involving 34,847 cancer patients met the inclusion criteria. Overall, SGLT2 inhibitor use was associated with a significantly reduced risk of CTRCD (RR: 0.47, 95% confidence interval: 0.33-0.68, P < 0.001), though significant heterogeneity was observed (I² = 70%). Subgroup analysis indicated a stronger protective effect in patients receiving anthracyclines (RR: 0.26) compared to those undergoing other treatments (RR: 0.73, P for subgroup difference = 0.001). Additionally, the cardioprotective effect was more pronounced in cohorts with a lower proportion of men (<55%, RR: 0.27) compared to those with a higher proportion (≥55%, RR: 0.75, P < 0.001). Sensitivity analyses, conducted by excluding one study at a time, consistently supported these findings, reinforcing their robustness. In conclusion, SGLT2 inhibitor use is associated with a lower risk of CTRCD in cancer patients, particularly those receiving anthracyclines. These findings highlight the potential role of SGLT2 inhibitors in mitigating cardiotoxicity during cancer therapy.

Chemotherapy has been confirmed as an effective treatment for advanced cervical cancer. However, whether combining PD-1/PD-L1 inhibitors with chemotherapy (PIC) offers superior efficacy remains a subject of debate. This meta-analysis aims to compare the antitumor effects and safety profile of PIC versus chemotherapy.

This study systematically reviews the efficacy and safety of the single or combined use of programmed factor 1 (PD-1)/programmed factor 1 ligand (PD-L1) inhibitors for treating metastatic or advanced renal cell carcinoma (RCC).

This meta-analysis aimed to evaluate the dose-response relationship between body mass index (BMI) and the risk of chemotherapy-induced peripheral neuropathy (CIPN) in cancer patients.
