Efficacy and safety of first-line treatments for advanced hepatocellular carcinoma patients: a systematic review and network meta-analysis.

Background: The first-line treatment for advanced hepatocellular carcinoma has evolved significantly. This study aimed to identify the most beneficial regimen. Methods: A systematic search was conducted from July 2012 to August 2024 across the following four databases: PubMed, Embase, Cochrane Library, and ClinicalTrials.gov. This search focused on phase III prospective randomized controlled trials that compared first-line treatment for advanced hepatocellular carcinoma. Results: Seventeen studies involving 10322 patients were included in this network meta-analysis. Of the studies we included, twelve studies were global multicenter clinical studies, four were initiated in China, and one was initiated in Korea. The results of our statistical analysis suggest that Hepatic artery infusion chemotherapy with oxaliplatin plus fluorouracil (HAIC-FO) demonstrated significant overall survival (OS) benefits compared with most treatments, including various immune checkpoint inhibitors (ICIs) and anti-vascular endothelial growth factor tyrosine kinase inhibitors (VEGF-TKIs). In terms of OS, HAIC had shown similar efficacy with sorafenib plus FOLFOX (HR, 0.88; 95% CI: 0.37-2.09) and transcatheter arterial chemoembolization (TACE) combined with lenvatinib (HR, 0.69; 95% CI: 0.30-1.56). Notably, immune-related treatments, such as ICIs combined with anti-VEGF therapies, also showed improved OS compared with anti-VEGF-TKIs alone. In terms of progression-free survival (PFS), HAIC-FO outperformed anti-VEGF-TKI monotherapy, ICI monotherapy, and several ICI combinations. However, it was not superior to lenvatinib plus TACE or lenvatinib plus pembrolizumab. Based on the Surface Under the Cumulative Ranking Curve (SUCRA) values, HAIC-FO was ranked the most effective in terms of OS (SUCRA = 0.961) and objective response rate (ORR) (SUCRA = 0.971). The results of the subgroup analysis suggested that HAIC-FO achieved the best OS benefit in the macrovascular invasion (MVI) and extrahepatic spread (EHS) subgroup (SUCRA = 0.99) and that tremelimumab combined with durvalumab achieved the best OS benefit in the Asian subgroup (SUCRA = 0.88). Conclusion: This systematic review and network meta-analysis suggest that HAIC-based therapies may become a potential first-line treatment option for advanced HCC, especially for patients in Mainland China with MVI and EHS. Additionally, immune-related treatments may be more suitable for Asian populations.

Irinotecan plus raltitrexed as second-line treatment in locally advanced or metastatic colorectal cancer patients: a prospective open-label, single-arm, multi-center, phase II study.

BACKGROUND: Colorectal cancer is the third most common cancer and the second leading cause of cancer death. There are limited therapeutic options for the treatment of locally advanced or metastatic colorectal cancers which fail first-line chemotherapy. Phase I/II studies showed that the combined application of the raltitrexed and irinotecan has significant synergistic effect and acceptable toxicity. However, most of these previous studies have relatively small sample size. METHODS: This is a prospective open-label, single-arm, multi-center, Phase II trial. Brief inclusion criteria: patients were aged 18 to 75 years with locally advanced or metastatic colorectal cancer after failure of 5-FU and oxaliplatin therapy. Enrolled patients received raltitrexed (3 mg/m2, d1) and irinotecan (180 mg/m2, d1) each 21-day cycle until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival, and the secondary endpoints were disease control rate, objective response rate, overall survival and safety. RESULTS: A total of 108 patients were enrolled between September 2016 and May 2020. The median age was 61 years, ECOG 1 score accounts for 67.6%, the rest were ECOG 0. A total of 502 cycles were completed, with an average of 4.6 cycles and a median of 4 cycles. 108 patients were evaluated, with an objective response rate of 17.6%, and disease control rate of 76.9%. The median follow-up time was 27 months (range:3.1-61.0 m) at data cut-off on March 2023. Median progression-free survival was 4.9 months (95% CI 4.1-5.7) and median overall survival was 13.1 months (95% CI 12.2-15.5). The most common adverse events that were elevated are alanine aminotransferase increased, aspartate aminotransferase increased, fatigue, diarrhoea, neutrocytopenia, thrombocytopenia, hypohemoglobin, and leukocytopenia. Most of the adverse events were Grade I/II, which were relieved after symptomatic treatment, and there were no treatment-related cardiotoxicities and deaths. CONCLUSIONS: The combination of raltitrexed and irinotecan as second-line treatment for mCRC could be a reliable option after failure of standard 5-Fu-first-line chemotherapy in locally advanced or metastatic colorectal cancers, especially for patients with 5-FU intolerance (cardiac events or DPD deficiency patients). TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03053167, registration date was 14/2/2017.

Construction of the prognostic model for small-cell lung cancer based on inflammatory markers: A real-world study of 612 cases with eastern cooperative oncology group performance score 0-1.

OBJECTIVES: This research aimed to explore the relationship between pre-treatment inflammatory markers and other clinical characteristics and the survival of small-cell lung cancer (SCLC) patients who received first-line platinum-based treatment and to construct nomograms for predicting overall survival (OS) and progression-free survival (PFS). METHODS: A total of 612 patients diagnosed with SCLC between March 2008 and August 2021 were randomly divided into two cohorts: a training cohort (n = 459) and a validation cohort (n = 153). Inflammatory markers, clinicopathological factors, and follow-up information of patients were collected for each case. Cox regression was used to conduct univariate and multivariate analyses and the independent prognostic factors were adopted to develop the nomograms. Harrell's concordance index (C-index) and time-dependent receiver operating characteristic curve were used to verify model differentiation, calibration curve was used to verify consistency, and decision curve analysis was used to verify the clinical application value. RESULTS: Our results showed that baseline C-reactive protein/albumin ratio, neutrophil/lymphocyte ratio, NSE level, hyponatremia, the efficacy of first-line chemotherapy, and stage were independent prognostic factors for both OS and PFS in SCLC. In the training cohort, the C-index of PFS and OS was 0.698 and 0.666, respectively. In the validation cohort, the C-index of PFS and OS was 0.727 and 0.747, respectively. The nomograms showed good predictability and high clinical value. Also, our new clinical models were superior to the US Veterans Administration Lung Study Group (VALG) staging for predicting the prognosis of SCLC. CONCLUSIONS: The two prognostic nomograms of SCLC including inflammatory markers, VALG stage, and other clinicopathological factors had good predictive value and could individually assess the survival of patients.

Effects of Apatinib on the Pharmacokinetics of Nifedipine and Warfarin in Patients with Advanced Solid Tumors.

BACKGROUND AND PURPOSE: Apatinib is a small-molecule tyrosine kinase inhibitor for the treatment of recurrent or progressive advanced-stage gastric adenocarcinoma or gastroesophageal junction cancer. The in vitro inhibition studies suggested that apatinib exerted potent inhibition on CYP3A4 and CYP2C9. To evaluate the potential of apatinib as a perpetrator in CYP450-based drug-drug interactions in vivo, nifedipine and warfarin were, respectively, selected in the present study as the probe substrates of CYP3A4 and CYP2C9 for clinical drug-drug interaction studies. Since hypertension and thrombus are common adverse effects of vascular targeting anticancer agents, nifedipine and warfarin are usually coadministered with apatinib in clinical practice. METHODS: A single-center, open-label, single-arm, and self-controlled trial was conducted in patients with advanced solid tumors. The patients received a single dose of 30 mg nifedipine on Day 1/14 and a single dose of 3 mg warfarin on Day 3/16. On Day 9-21, the subjects received a daily dose of 750 mg apatinib, respectively. The pharmacokinetics of nifedipine and warfarin in the absence or presence of apatinib was, respectively, investigated. RESULTS: Compared with the single oral administration, coadministration with apatinib contributed to the significant increases of AUC0-48h and Cmax of nifedipine by 83% (90% confidence interval [CI] 1.46-2.31) and 64% (90% CI 1.34-2.01), respectively. Similarly, coadministration with apatinib contributed to the significant increases of AUC0-t and Cmax of S-warfarin by 92% (90% CI 1.68-2.18) and 24% (90% CI 1.10-1.39), respectively. CONCLUSION: Concomitant apatinib administration resulted in significant increases in systemic exposure to nifedipine and S-warfarin. Owing to the risk of pharmacokinetic drug-drug interactions based on CYP3A4/CYP2C9 inhibition by apatinib, caution is advised in the concurrent use of apatinib with either CYP2C9 or CYP3A4 substrates.

PD-L1 upregulation accompanied with epithelial-mesenchymal transition attenuates sensitivity to ATR inhibition in p53 mutant pancreatic cancer cells.

Pancreatic cancer is a highly progressive malignant tumor for which there is a critical unmet need for novel therapeutic strategies. A previous study of the authors indicated that VE-821, a selective inhibitor of the ataxia-telangiectasia-mutated and rad3-related protein (ATR), has antitumor efficacy. In this study, the effect of programmed death ligand 1 (PD-L1) on the sensitivity to VE-821 was investigated in p53 mutant pancreatic cancer cells. These results show that BxPC-3 cells exhibited higher sensitivity to VE-821 than mesenchymal PANC-1 cells, which were more migratory and had higher expressions of PD-L1 and CD44. When VE-821 was applied to two cells, epithelial-to-mesenchymal transition (EMT) was induced in PANC-1 cells with concomitant upregulation of PD-L1 and CD44, while BxPC-3 cells did not manifest these changes. Attenuation of PD-L1 expression suppressed VE-821-induced EMT, inhibited cell migration, and downregulated CD44 expression. Furthermore, PD-L1 inhibition partially reversed the activation of AKT/ERK, enhanced DNA damage, and increased VE-821 sensitivity in PANC-1 cells. Analysis of GEPIA data showed positive correlation of PD-L1 expression with EMT-related transcription factors. Taken together, these results suggest a novel function of PD-L1 in regulating response to ATR inhibition. These data highlight PD-L1 inhibition as a promising target to enhance sensitivity to ATR inhibitors in mesenchymal pancreatic cancer.

Efficacy of Thalidomide in Preventing Delayed Nausea and Vomiting Induced by Highly Emetogenic Chemotherapy: A Randomized, Multicenter, Double-Blind, Placebo-Controlled Phase III Trial (CLOG1302 study).

Purpose We examined the efficacy and safety of thalidomide (THD) for the prevention of delayed nausea and vomiting in patients who received highly emetogenic chemotherapy (HEC). Patients and Methods In a randomized, double-blind, active-controlled, phase III trial, chemotherapy-naive patients with cancer who were scheduled to receive HEC that contained cisplatin or cyclophosphamide-doxorubicin/epirubincin ≥ 50 mg/m2 regimens were randomly assigned to a THD group (100 mg twice daily on days 1 to 5) or placebo group, both with palonosetron (0.25 mg on day 1) and dexamethasone (12 mg on day 1; 8 mg on days 2 to 4). Primary end point was complete response to vomiting-no emesis or use of rescue medication-in the delayed phase (25 to 120 h). Nausea and anorexia on days 1 to 5 were evaluated by the 4-point Likert scale (0, no symptoms; 3, severe). Quality of life was assessed by the European Organization for Research and Treatment of Cancer QLQ-C30 version 3 questionnaire on days -1 and 6. Results Of 656 patients, 638 were evaluable: 317 in the THD group and 321 in the control group. Compared with placebo, delayed and overall (0 to 120 h) complete response rates to vomiting were significantly higher with THD: 76.9% versus 61.7% ( P < .001) and 66.1% versus 53.3% ( P = .001), respectively. Rates of no nausea were also higher in the THD group (delayed: 47.3% v 33.3%; P < .001; overall: 41% v 29.6%; P = .003), and mean scores of anorexia were lower overall (0.44 ± 0.717 v 0.64 ± 0.844; P = .003). Adverse effects were mild to moderate. The THD group had increased sedation, dizziness, constipation, and dry mouth, but experienced better quality of life after chemotherapy. Conclusion Thalidomide combined with palonosetron and dexamethasone significantly improved HEC-induced delayed nausea and vomiting prevention in chemotherapy-naive patients.

CD44 family proteins in gastric cancer: a meta-analysis and narrative review.

With a meta-analysis and narrative review, we evaluated the clinical and prognostic role of all CD44 family proteins in gastric cancer (GC). Literatures published up to August 2014 were searched on PubMed. Among the 37 eligible studies (6606 patients), 34 were included in meta-analysis, and 10 were subjected to narrative review. With meta-analysis, standard CD44 (CD44s) was demonstrated to predict reduced overall survival (OS) (HR = 1.93, 95% CI: 1.58-2.34, PHR = 0.0222) and disease free survival (HR = 3.13, 95% CI: 1.02-9.68, PHR = 0.0469), advanced N-stage (RR = 1.12, 95% CI: 1.04-1.21, PRR = 0.0019), and distant metastasis (RR = 2.14, 95% CI: 1.46-3.14, PRR < 0.0001) of GC. CD44 variant 6 (CD44v6) in GC might influence OS (5 studies; HR = 1.27, 95% CI: 0.75-2.14, PHR = 0.3783; 4 studies; HR = 1.52, 95% CI: 1.09-2.14, PHR = 0.0139), while significantly associated with N-stage (RR = 1.23, 95% CI: 1.03-1.48, PRR = 0.0240), M-stage (RR = 2.54, 95% CI: 1.08-6.00, PRR = 0.0333), TNM-stage (RR = 1.72, 95% CI: 1.18-2.50, PRR = 0.0045), Lauren type (RR = 0.67, 95% CI: 0.50-0.91, PRR = 0.0106), lymphatic invasion (RR = 1.13, 95% CI: 1.04-1.23, PRR = 0.0057), and liver metastasis (RR = 3.20, 95% CI: 1.94-5.27, PRR < 0.0001) of the disease. Moreover, a narrative review was performed for CD44 isoforms, such as v3, v5, v7, v8-10, and v9, in GC. In conclusion, CD44s and CD44v6 as evaluated by immunohistochemistry, respectively, predicts the prognosis and disease severity of GC.

Glutathione S-transferase M1 polymorphism and colorectal cancer risk in Chinese population.

Glutathione S-transferase M1 (GSTM1) polymorphism has been proven to be associated with risks of several cancers. However, previous studies on the association between GSTM1 polymorphism and colorectal cancer risk in Chinese population reported controversial results. We performed a meta-analysis of 13 studies which were identified through the literature search in PubMed and Wanfang databases. The strength of the association between GSTM1 polymorphism and colorectal cancer risk was measured by odds ratio (OR) with corresponding 95% confidence interval (95% CI). Overall, GSTM1 null mutation was significantly associated with a risk of colorectal cancer in Chinese population (OR = 1.37, 95% CI 1.12 to 1.68, P = 0.002). Sensitivity analyses by omitting those studies in turns did not materially alter the overall pooled ORs. The cumulative meta-analyses further showed a trend of an obvious association between GSTM1 null mutation and risk of colorectal cancer in Chinese population as information accumulated by year. The findings from our meta-analysis suggest that GSTM1 null mutation is significantly associated with a risk of colorectal cancer in Chinese population.

Insulin therapy contributes to the increased risk of colorectal cancer in diabetes patients: a meta-analysis.

BACKGROUND: Recent epidemiological studies suggest that treatment with insulin may promote cancer growth. The present systematic review and meta-analysis of published observational studies was conducted to assess the risk of cancer during treatment with insulin. MATERIALS AND METHODS: A compressive search was conducted through MEDLINE, PubMed, Web of Science, EMBASE, and Chinese Biomedical Literature databases (CBM). Pooled relative risks (RRs) and 95% confidence intervals (CIs) were calculated with a random-effects model. RESULTS: A total of four studies with one case-controls study and three cohort studies comparing the insulin therapy and colorectal cancer susceptibility were identified. When all four studies were analyzed, the summary RRs were 1.61 (95% CI = 1.18-1.35) in a random-effects model for individuals with insulin therapy, compared with individuals without insulin therapy, which suggests a statistically significant association between insulin use and colorectal cancer. CONCLUSIONS: Our findings provides the evidence that insulin therapy may contribute to the risk of colorectal cancer.
