  • Efficacy and safety of capecitabine combined with irinotecan versus capecitabine combined with oxaliplatin in treatment of advanced/metastatic colorectal cancer: a systematic review

    ObjectiveTo systematically review the efficacy and safety of capecitabine combined with irinotecan (CAPIRI) versus capecitabine combined with oxaliplatin (CAPOX) for patients with advanced/metastatic colorectal cancer.MethodsPubMed, EMbase, The Cochrane Library, VIP, WanFang Data and CNKI databases were electronically searched to collect randomized controlled trials (RCTs) on CAPIRI versus CAPOX for patients with advanced/metastatic colorectal cancer from inception to August 2018. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 12 RCTs involving 1 049 patients were included. The results of meta-analysis showed that: there were no significant differences in complete response (CR), partial response (PR), stable disease (SD), progression disease (PD), overall respond rate (ORR), median progression-free survival (mPFS), and median overall survival (mOS) between two groups (P>0.05). However, CARIRI group was lower on the disease control rate (RR=0.93, 95%CI 0.86 to 1.00, P=0.04) than CAPOX group. Incidence of diarrhea was higher in CAPIRI group (RR=1.83, 95%CI 1.37 to 2.45, P<0.000 1). However, the incidence rate of peripheral neurotoxicity in CAPOX group was higher (RR=0.13, 95%CI 0.05 to 0.35, P<0.000 1). There were no significant differences between two groups in the incidence rates of nausea and vomiting, hand-foot syndrome, anemia, thrombocytopenia, leukocytopenia and alopecia (P>0.05).ConclusionsCurrent evidence shows that two groups are equivalent in terms of curative effects. CAPIRI has a higher incidence rate of diarrhea, while CAPOX has a higher risk of peripheral neurotoxicity. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.

  • Inadequate efficacy or intolerance with conventional synthetic disease-modifying antirheumatic drug in rheumatoid arthritis patients: a systematic review of pharmacoeconomic evaluation

    ObjectivesTo review the pharmacoeconomic evaluation of rheumatoid arthritis patients with an inadequate efficacy or intolerance with conventional synthetic disease modifying antirheumatic drugs (csDMARDs).MethodsCNKI, WanFang Data, VIP, PubMed, EMbase, Web of Science and The Cochrane Library were electronically searched to collect pharmacoeconomic studies about rheumatoid arthritis patients with an inadequate efficacy or intolerance with csDMARDs from inception to February 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of the included studies, then, descriptive analysis was performed.ResultsA total of 16 studies were included, where most compared the economics of different treatment methods from the perspective of the payer by cohort or individual model. The economic costs in the studies were primarily on direct cost. Sensitivity analyses were used to prove the robustness of the main analysis in each study. Biological disease-modifying antirheumatic drugs (bDMARDs) might be more cost-effective than csDMARDs. In addition, compared with the bDMARDs, new-marketed targeted synthetic disease-modifying antirheumatic drugs (tsDMARDs) might be more cost-effective.ConclusionsIt could be considered to implement more new marketed tsDMARDs to improve patients’ condition to reduce the economic burden and optimize the allocation of health care resources.

  • Progress in the application of clinical evidence in health decision-making: experience from NICE in the UK

    Traditional randomized controlled trial and real-world study have different advantages in internal validity and external extensibility, respectively. With the development of evidence-based health decisions, randomized controlled trial was no longer the only golden standard of interventional study, the research evidence of the real world was gradually involved in health decisions. This study mainly analyzed the requirements of evidence and actual application of evidence in the evaluation of the effectiveness of NICE in the UK. It was found that NICE still used the results of randomized controlled trials as a primary basis. Although real-world research has developed rapidly in recent years, it was limited used in health decision because of its bias by design and other factors. However, in recent years, real-world evidence has played a significant role in the field of innovative drugs or diseases that lack therapeutic drugs. With the improvement of real-world research in experimental design and data analysis, it is expected that it will play a more important role in health decision-making.

  • Pharmacoeconomics of ferric carboxymaltose in patients with iron deficiency anemia: a systematic review

    ObjectiveTo systematically review the pharmacoeconomics of high-dose intravenous iron ferric carboxymaltose in the treatment of patients with iron deficiency anemia. MethodsPharmacoeconomic studies of ferric carboxymaltose in the treatment of patients with iron deficiency anemia were searched in PubMed, The Cochrane Library, York University CRD, Web of Science, EBSCO, CNKI, WanFang Data and VIP databases, and relevant health technology assessment websites from inception to September 30th, 2021. A descriptive analysis was performed after two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. ResultsA total of 11 studies were included, most of them compared the health economics of ferric carboxymaltose with other therapies from a hospital perspective. The main costs included in these studies were costs for iron, infusion, blood transfusion, EPO, hospitalization, and transportation, as well as productivity cost. The ferric carboxymaltose was presumed to be more economical than other intravenous irons. ConclusionIt is suggested that the ferric carboxymaltose be considered in more clinical settings to improve the ischemic condition of patients with iron deficiency anemia, so as to promote the rational utilization of medical resources.

  • Three-dimensional study of facial soft tissue changes in patients with skeletal Class Ⅲ malocclusion before and after orthognathic surgery

    ObjectiveTo investigate the changes of facial soft tissue before and after orthognathic surgery in patients with skeletal Class Ⅲ malocclusion.MethodsBetween August 2016 and April 2017, 30 patients with skeletal Class Ⅲ malocclusion who underwent maxillary LeFort Ⅰ osteotomy and sagittal split mandible osteotomy were selected as study subjects. Among them, 11 were male and 19 were female with an average age of 22.6 years (range, 18-35 years). Full head CT scan and facial soft tissue three-dimensional image scan were performed within 2 weeks before surgery and at 6 months after surgery. A three-dimensional facial image model was established using Artec Studio 11.0 and CMF Proplan 3.0 software to analyze the facial soft tissue changes before and after surgery. The soft tissue anatomical landmarks in each area of the face were measured and compared before and after surgery.ResultsThe area of facial soft tissue change after surgery was the maxillary nose and the lower jaw area, and the two sides did not exceed the vertical boundary of the outer canthus. After surgery, the horizontal points of bilateral alar bases and bilateral cheeks changed significantly (P<0.05). The sagittal points of subnasale, pronasale, bilateral alar bases, upper lip margin significantly forwarded (P<0.05); the sagittal points of the bilateral cheilions, lower lip margin, midpoint of chin-lip groove, pogonion, and menton significantly backwarded (P<0.05). The vertical points of the upper lip margin, bilateral cheilions, lower lip margin, bilateral cheeks, and bilateral inner canthus points significantly descended (P<0.05), and the vertical point of the menton significantly elevated (P<0.05). After surgery, the nasal column was significantly shortened, the upper lip got longer and the alar base widened when compared with those before surgery (P<0.05).ConclusionThe overall change of face after double jaw surgery is shorter and fuller, and the mandible of facial soft tissue change is larger than that of maxillary, which suggests that the postoperative facial changes should be taken into account in the surgical design.
