ABSTRACT.Although new chemotherapeutic drugs have been applied constantly, their efficacy for non-small cell lung cancer (NSCLC) is still not satisfactory. In recent years, epidemiological investigations have shown that lung cancer may be induced by chronic Chlamydia pneumoniae (Cpn) infection, since stable high titers of Cpn antibodies, especially IgA, are a hallmark of chronic infections. Azithromycin is commonly used for the treatment of Cpn infections; however, there are only few reports regarding the application of azithromycin (A) combined with paclitaxel and cisplatin (TP) for advanced NSCLC. Considering that patients with NSCLC have a higher rate of Cpn infection, we proposed to employ azithromycin for Cpn infection in chemotherapy for advanced NSCLC. The aim of this study was to explore the effects of azithromycin on chemotherapy for NSCLC. A total of 86 patients with stage III-IV NSCLC were randomly divided into TP and ATP groups; the characteristics of patients in the two groups showed no significant differences. The TP group was treated with paclitaxel and cisplatin, and the ATP group was treated with Azithromycin, paclitaxel and cisplatin in lung cancer azithromycin combined with TP for at least 4 weeks, followed by evaluation and comparison of efficacy, side effects and patients' quality of life before and after chemotherapy between the two groups. Testing for Cpn infection revealed a significant difference in the case number before and after therapy in the ATP group (P < 0.01) compared with the TP group (P > 0.05), and a statistical difference was observed (P < 0.01) between the ATP and TP groups after treatment. The changes in quality of life of patients after two different chemotherapy regimens were statistically significant (P < 0.05), but there was a significant difference in only cognitive function after treatment. The changes in symptom scores of patients after the two different chemotherapy regimens were statistically significant (P < 0.05), but there was a significant difference in only shortness of breath and cough after treatment. Kaplan-Meier estimate was utilized to describe the survival function of patients in the two groups. The median survival time was 12.0 months for the TP group and 13.0 months for the ATP group. One-year survival rates of the TP and ATP groups were 45.0 and 75.0%, respectively, which were significantly different (P < 0.05). Our study of azithromycin+paclitaxe l+cisplatin on stage III-IV NSCLC patients achieved favorable results in terms of side effects and overall survival.
Continuous endovenous administration of Endostar (CE) gradually replaced drip intravenous administration of Endostar (DE) in lung squamous cell carcinoma (SCC) treatment presently, but the efficacy and safety of CE and DE which is better in advanced lung SCC are yet unclear. To evaluate the feasibility of CE as an alternative to DE with gemcitabine/cisplatin (GP) chemotherapy. Data were collected from patients admitted with locally advanced or metastatic lung SCC from January 2011 to April 2015, including the patients’ characteristics, the therapeutic regimen, the treatment effectiveness, and toxicity. There are 71 patients with pathologically confirmed lung SCC retrospectively assigned to a treatment (CE) group of 48 patients and a control (DE) group of 23 patients. The response of each tumor to the therapy was assessed every 2 cycles by a chest and upper abdomen computed tomography for the comparison of curative effects and adverse reactions. Compared with the DE group, the response rate and disease control rate were noninferior in the CE group. The median progression-free survival and overall survival in the CE and DE groups were no significantly difference (5.5 vs 5.5 months, P = .141; 22.9 vs 14.3 months, P = .053). Increased progression-free survival (PFS) for patients in CE group was observed across 3 subgroups analyzed. There was a 35.7% reduction in the total dose of Endostar per cycle in the CE group compared with that in the DE group. Thus, in combination with GP chemotherapy, CE could be a suitable alternative to DE in locally advanced or metastatic SCC patients, resulting in less hemoptysis, less treatment time, and lower costs.
BackgroundSpontaneous reporting of adverse drug events (ADEs) has long been the cornerstone of pharmacovigilance. Medical institutions in China have been a major source of ADE case reports, but the proportion of reports from tertiary hospitals is low due to the serious underreporting of case reports. The same problem existed in the Second Affiliated Hospital of Zhejiang University School of Medicine (SAHZU).ObjectiveIn order to increase the number of ADE reports and promote hospital pharmacovigilance, SAHZU’s clinical pharmacists established a pharmacist-led ADE management model. The aim of this paper is to introduce this management model and explore the advantages and disadvantages of the model.MethodsPharmacist-led ADE management model was gradually formed from 2015 to 2017 in the SAHZU. This “pharmacist-led” model is reflected not only in the fact that clinical pharmacists are the main reporters of SAHZU’s ADEs but also in that they are the main groups to analyze and manage ADE and drug errors. The sources of ADEs reported by clinical pharmacists mainly include pharmacy rounds, ADE-related pharmacist consultations, centralized monitoring, ADE warning signal analysis, newly introduced drug evaluations, and drug safety research.ResultsA total of 533 ADEs were reported by SAHZU to China’s spontaneous reporting system (SRS) in 2017, while the data in 2012 was 177, with an increase by 201%. In 2012, the proportion of “new” and “serious” reports was 16.4%. The proportions during the period from 2015 to 2017 were 41.4%, 60.8%, and 52.2%, respectively, which were statistically significant compared with the proportion in 2012. The proportion of ADEs reported by clinical pharmacists during the period from 2014 to 2017 were 51.5%, 57.3%, 68.8%, and 90.8%, respectively, which were statistically significant compared with the proportion in 2013 (P<0.05). There was a correlation between the proportions of severe ADEs and the proportion of ADEs reported by clinical pharmacists (r=0.873, P=0.023). Four hundred eighty four ADE cases reported by clinical pharmacists to China’s SRS in 2017 were mainly found in rounds of clinical pharmacists (74.17% [359/484]).ConclusionThe pharmacist-led pharmacovigilance working model significantly increased the quantity and quality of ADE reporting in SAHZU and promoted pharmacovigilance. This model is worth developing in Chinese tertiary hospitals and the following hospitals, where the physicians working there spend little time and energy on ADE reporting or the cost of physicians is high, while the clinical pharmacist team has strong professional skills.
ObjectivesIt is unclear what is driving rising colorectal cancer (CRC) treatment costs in China, whether an adjustment in drug prices changes use and total cost. This study aims to estimate trends in drug use, prescribing patterns and spending for antineoplastic drug therapies for CRC in major cities of China.MethodsInformation from 128 811 antineoplastic drug prescriptions in CRC was retrospectively collected from the Hospital Prescription Analysis Cooperative Project. The prescriptions extracted included demographic information of patients, the generic name and the price of antineoplastic drugs. The Mann-Kendall and Cochran-Armitage trend test was used to estimate the trends of antineoplastic agent usage.ResultsThe number of antineoplastic prescriptions ranged from 18 966 in 2015 to 34 219 in 2019. Among the prescriptions collected in this study, the annual cost of antineoplastic drugs increased by 117.2%, and average prescription cost increased by 20%. Throughout the study period, the most prescribed antineoplastic drugs were capecitabine, oxaliplatin, fluorouracil and irinotecan, representing 49%, 27%, 21% and 9% of (per cent of visits (PV)). The PV of bevacizumab and cetuximab increased by 494% and 338% (from 1.8% and 1.3% in 2015 to 10.7% and 5.7% in 2019). In prescribing patterns of antineoplastic agents, monotherapy gradually decreased, while combination therapy, especially three-drug combination, increased significantly from 1.35% to 7.31%.ConclusionThis study estimated recent trends of antineoplastic drug use and expenditure for Chinese patients with CRC. These results would inform CRC treatment decisions, including health insurance negotiation, precision therapy access, allocation of research funding and evaluation of the financial burden of CRC drug treatment.
