OBJECTIVE To evaluate the cost-effectiveness of rezivertinib versus gefitinib as first-line treatment for epidermal growth factor receptor (EGFR) mutation-positive advanced non-small cell lung cancer (NSCLC) from the perspective of the Chinese healthcare system. METHODS A Markov model was constructed based on the REZOR trial data, with a cycle length of 3 weeks and a study duration of 5 years. Both costs and health outcomes were discounted at an annual rate of 5%. A cost-utility analysis was conducted using 3 times China’s 2024 per capita gross domestic product as the willingness-to-pay (WTP) threshold. The economic differences between the rezivertinib regimen versus the gefitinib regimen were evaluated using the incremental cost- effectiveness ratio (ICER) and incremental net monetary benefit (INMB). Sensitivity and scenario analyses were performed to verify the robustness of the model. RESULTS Compared to the gefitinib regimen, the rezivertinib regimen saved 225 310.47 yuan and gained an additional 0.57 quality- adjusted life years (QALYs), resulting in an ICER of -395 562.80 yuan/QALY, which was much lower than the WTP threshold of this study, indicating that rezivertinib had an absolute economic advantage. The INMB analysis (389 041.26 yuan) further validated this conclusion. One-way and probabilistic sensitivity analyses confirmed the robustness of the model. Scenario analysis, incorporating a 15% reduction in drug prices and adjustments to the utility values for progression free survival and progression disease, yielded consistent results with the base case analysis. CONCLUSIONS Compared to gefitinib, rezivertinib as a first-line treatment for EGFR mutation-positive advanced NSCLC has an absolute economic advantage.

OBJECTIVE To comprehensively evaluate the quality of adverse drug reaction (ADR) reports in clinical departments or ward (hereinafter referred to as “department”) based on game theory combinatorial weighting-technique for order preference by similarity to ideal solution (TOPSIS)-rank-sum ratio (RSR) method, providing a reference for the further standardization of ADR reporting. METHODS Based on relevant documents and scoring criteria, the ADR report quality evaluation standards previously developed by our team were modified. Using game theory principles, the fusion of subjective and objective weights for each indicator was determined. A game theory combinatorial weighting-TOPSIS-RSR model was developed to evaluate and categorize the quality of raw ADR reports submitted by departments to the pharmacy department at Bozhou Hospital of Anhui Medical University. RESULTS A total of 222 ADR reports from 23 departments were included. The game theory combinatorial weighting method identifies weak points in management, such as ADR symptoms and signs, the description of underlying diseases, timing of ADR, by optimizing the weightings of the indicators. The TOPSIS-RSR method calculates that the mean relative closeness of the departments was 0.401 7, indicating that the overall report quality ranged from moderate to substandard. 20095) Three departments, including neurosurgery, demonstrated medium reporting quality [estinate closeness (Ĉ)i ≥0.506], while two departments, such as the respiratory department,were rated as unqualified (Ĉi<0.278). The remaining departments were all deemed qualified (0.278≤ Ĉi<0.506). CONCLUSIONS The developed game theory combinatorial weighting-TOPSIS-RSR method provides an effective approach for the quality evaluation of ADR reports, which not only balances subjective and objective weights but also facilitates comparisons among different departments. There is still room for improvement in the ADR report quality at the hospital.

OBJECTIVE To evaluate the cost-effectiveness of bevacizumab combined with erlotinib in the first-line treatment of advanced EGFR mutant non-squamous non-small cell lung cancer (NSCLC) from the perspective of China’s health system. METHODS A dynamic Markov model was established based on BEVERLY study data, with a cycle of 3 weeks, a research deadline until 99% of patients die, and an annual discount rate of 5%. The model outputs were total cost, quality-adjusted life year (QALY), and incremental cost-effectiveness ratio (ICER). Taking 3 times China’s per capita gross domestic product (GDP) in 2023 as the willingness-to-pay (WTP) threshold, the cost-utility analysis was used to evaluate the cost-effectiveness of bevacizumab combined with erlotinib (observation group) versus erlotinib alone (control group) in the first-line treatment of advanced EGFR mutant non-squamous NSCLC, and the single factor sensitivity analysis and probability sensitivity analysis were used to verify the robustness of the basic analysis results. RESULTS The results of the basic analysis showed that compared with the erlotinib therapy plan, ICER of bevacizumab combined with erlotinib was 1 452 243.01 yuan/QALY, which was more than 3 times China’s per capita GDP in 2023 (268 074 yuan/QALY) as the WTP threshold, indicating that bevacizumab combined with erlotinib was not cost-effective. The results of single factor sensitivity analysis showed that the cost of bevacizumab, the utility value of progression-free survival and progressed disease status had a great influence on the results. The results of probability sensitivity analysis showed that when the WTP threshold was 1 740 000 yuan/QALY, the probability of cost-effective of bevacizumab combined with erlotinib plan was 50%. CONCLUSIONS Compared with erlotinib alone, bevacizumab combined with erlotinib is not cost-effective in the first-line treatment of advanced EGFR mutant non-squamous NSCLC, when using 3 times China’s per capita GDP in 2023 as the WTP threshold.

OBJECTIVE To evaluate the cost-effectiveness of regorafenib in the treatment of hepatocellular carcinoma after failure of sorafenib from the perspective of Chinese health system. METHODS Based on a phase Ⅲ trial(RESORCE), the partition survival model (PSM) and Markov model were constructed. The cycle was set as four weeks, the duration of the study lasted for lifetime, the annual discount rate was 5%. Drug cost data was obtained from yaozhi.com, other cost data were obtained from Anhui Provincial Medical Insurance Bureau and related literature, and utility values were obtained from literature. The incremental cost-effectiveness ratio (ICER) was used as the evaluation index, and the value of willingness to pay (WTP) was three times of China’s gross domestic product (GDP) per capita in 2022; one-way sensitivity analysis and probabilistic sensitivity analysis were used to verify the robustness of the basic analysis results. RESULTS The incremental cost of regorafenib group versus placebo group in PSM and Markov model was 112 116.95 yuan and 96 617.19 yuan, respectively. The incremental effectiveness was 0.31 QALYs and 0.32 QALYs, respectively. The ICERs were 360 751.01 yuan/QALY and 301 114.45 yuan/QALY, which were both greater than the value of WTP; regorafenib was not cost-effective. Results of one-way sensitivity analysis showed that the utility of progression-free survival and progressive disease, the unit cost of regorafenib had the greatest influence on the results, but ICER was always greater than the WTP within the floating range of each parameter. Under the WTP of 3 times China’s per capita GDP in 2022, the probabilities of regorafenib with cost-effectiveness were 0.8% (PSM) and 11.4% (Markov). CONCLUSIONS Under the WTP of 3 times the per capita GDP of China, regorafenib is not cost-effective in the treatment of hepatocellular carcinoma after failure of sorafenib treatment, compared with placebo.

OBJECTIVE To compare the efficacy, safety and economy of tacrolimus (TAC), cyclosporin A (CsA), cyclophosphamide (CTX) and rituximab (RTX) in the treatment of membranous nephropathy (MN). METHODS Retrieved from Pubmed, the Cochrane Library, Wanfang data, CNKI and health technology assessment (HTA) official website, HTA reports, systematic reviews/meta-analysis and pharmacoeconomic studies about TAC, CsA, CTX and RTX combined with glucocorticoid in the treatment of MN were collected during the inception and Mar. 2022. After data extraction and quality evaluation, descriptive analysis was performed on the results of the included studies. RESULTS A total of 15 articles were included, involving 13 systematic reviews/meta-analysis and 2 pharmacoeconomic studies. In terms of efficacy, TAC and CsA showed significant advantages in increasing the response rate, and could improve the levels of urine protein, serum albumin, serum creatinine and serum total cholesterol. In terms of safety, the incidence of adverse reaction induced by TAC, CsA and RTX was low and the symptoms were mild. In terms of economics, CTX cost lower but caused severe adverse reaction; TAC cost higher but showed higher remission rate and good safety. CONCLUSIONS TAC combined with glucocorticoid may be the recommended scheme for MN.

OBJECTIVE To compare the efficacy and safety of icotinib and gefitinib in the treatment of epidermal growth factor receptor (EGFR)-mutated advanced non-small cell lung cancer (NSCLC). METHODS The data of 146 patients with EGFR- mutant advanced NSCLC of our Hospital from December 2015 to September 2021 were retrospectively analyzed and divided into the gefitinib group (73 cases) and the icotinib group (73 cases) according to the drug use. Patients in the gefitinib group were given 0.25 g of gefitinib tablets once a day orally by single drug or combined with conventional chemotherapy, while patients in the icotinib group were given 125 mg of icotinib hydrochloride tablets three times a day orally by single drug or combined with conventional chemotherapy. Short-term efficacy, progression-free survival (PFS) were observed; Cox regression model was used to analyze the factors affecting the prognosis of patients; the occurrence of ADR were observed in the two groups. RESULTS There was no statistically significant difference in the objective remission rate, disease control rate, and the incidence of grade 1-2 and grade 3-4 adverse drug reactions between the two groups (P>0.05); median PFS was significantly better in the icotinib group than in the gefitinib group (P=0.048). Results of subgroup analysis based on patients basic information showed that compared with the gefitinib group, PFS of female [HR=0.57,95%CI(0.34,0.96),P=0.031] and non-brain metastatic patients [HR=0.58,95%CI(0.36,0.91),P=0.017] in icotinib group were prolonged significantly. Results of regression model analysis showed that EGFR19 exon Del mutation [HR=0.50, 95%CI(0.25,1.00), P=0.049], EGFR21 exon L858R mutation [HR=0.44, 95%CI(0.21,0.89), P=0.022] and icotinib treatment [HR=0.65, 95%CI (0.44,0.96), P=0.030] were influential factors for prognosis. CONCLUSIONS The short-term efficacy and safety of icotinib and gefitinib in the treatment of EGFR- mutant advanced NSCLC are comparable, but icotinib can significantly prolong the patients’ PFS; EGFR19 exon Del, EGFR21 exon L858R mutations and icotinib treatment are factors affecting patients’ prognosis.
