The management strategies of cancer-associated anorexia: a critical appraisal of systematic reviews.

ABSTRACT:

Background

Cancer-related anorexia remains one of the most prevalent and troublesome clinical problems experienced by patients with cancer during and after therapy. To ensure high-quality care, systematic reviews (SRs) are seen as the best guide. Considering the methodology quality of SRs varies, we undertook a comprehensive overview, and critical appraisal of pertinent SRs.

Methods

Eight databases (between the inception of each database and September 1, 2017) were searched for SRs on the management of cancer-related anorexia. Two researchers evaluated the methodological quality of each SR by using the Revised Assessment of Multiple Systematic Reviews (R-AMSTAR) checklist. Characteristics of the "high quality" SRs were abstracted, included information on relevant studies numbers, study design, population, intervention, control, outcome and result.

Results

Eighteen SRs met the inclusion criteria. The R-AMSTAR scores of methodological quality ranged from 18 to 41 out of 44, with an average score of 30. Totally eight SRs scored ?31 points, which showed high methodological quality, and would be used for data extraction to make summaries. Anamorelin had some positive effects to relieve cancer anorexia-cachexia syndrome (CACS) and improve the quality of life (QoL). Megestrol Acetate (MA) could improve appetite, and was associated with slight weight gain for CACS. Oral nutritional interventions were effective in increasing nutritional intake and improving some aspects of QoL in patients with cancer who were malnourished or at nutritional risk. The use of thalidomide, Eicosapentaenoic Acid, and minerals, vitamins, proteins, or other supplements for the treatment of cachexia in cancer were uncertain, and there was inadequate evidence to recommend it to clinical practices, the same situation in Chinese Herb Medicine and acupuncture (acupuncture and related therapies were effective in improving QoL) for treating anorexia in cancer patients, warranting further RCTs in these areas.

Conclusions

Anamorelin, MA, oral nutrition interventions, and acupuncture could be considered to be applied in patients with cancer-related anorexia. Future RCTs and SRs with high quality on the pharmaceutical or non-pharmaceutical interventions of anorexia in cancer patients are warranted.

Project description:IntroductionOver the last years, the number of systematic reviews published is steadily increasing due to the global interest in this type of evidence synthesis. However, little is known about the characteristics of this research published in Portuguese medical journals. This study aims to evaluate the publication trends and overall quality of these systematic reviews.Material and methodsThis was a methodological study. We aimed the most visible Portuguese medical journals indexed in MEDLINE. Systematic reviews were identified through an electronic search (through PUBMED). We included systematic reviews published up to August 2020. Systematic reviews selection and data extraction were done independently by three authors. The overall quality critical appraisal using the A MeaSurement Tool to Assess systematic Reviews (AMSTAR-2) was independently assessed by three authors. Disagreements were solved by consensus.ResultsSixty-six systematic reviews published in 5 Portuguese medical journals were included. Most (n = 53; 80.3%) were systematic reviews without meta-analysis. Up to 2010 there was a steady increase in the number of systematic reviews published, followed by a period of great variability of publication, ranging from 1 to 10 in a given year. According to the systematic reviews' typology, most have been predominantly conducted to assess the effectiveness/efficacy of health interventions (n = 27; 40.9%). General and Internal Medicine (n = 20; 30.3%) was the most addressed field. Most systematic reviews (n = 46; 69.7%) were rated as being of "critically low-quality".ConclusionsThere were consistent flaws in the methodological quality report of the systematic reviews included, particularly in establishing a prior protocol and not assessing the potential impact of the risk of bias on the results. Through the years, the number of systematic reviews published increased, yet their quality is suboptimal. There is a need to improve the reporting of systematic reviews in Portuguese medical journals, which can be achieved by better adherence to quality checklists/tools.

Project description:BackgroundIn 2007, AMSTAR (A MeaSurement Tool to Assess systematic Reviews), a critical appraisal tool for systematic reviews (SRs), was published, and it has since become one of the most widely used instruments for SR appraisal. In September 2017, AMSTAR 2 was published as an updated version of the tool. This mixed-methods study aimed to analyze the extent of the AMSTAR 2 uptake and explore potential barriers to its uptake.MethodsWe analyzed the frequency of AMSTAR or AMSTAR 2 use in articles published in 2018, 2019 and 2020. We surveyed authors who have used AMSTAR but not AMSTAR 2 in the analyzed time frame to identify their reasons and barriers. The inclusion criterion for those authors was that the month of manuscript submission was after September 2017, i.e. after AMSTAR 2 was published.ResultsWe included 871 studies. The majority (N = 451; 52%) used AMSTAR 2, while 44% (N = 382) used AMSTAR, 4% (N = 31) used R-AMSTAR and others used a combination of tools. In 2018, 81% of the analyzed studies used AMSTAR, while 16% used AMSTAR 2. In 2019, 52% used AMSTAR, while 44% used AMSTAR 2. Among articles published in 2020, 28% used AMSTAR, while AMSTAR 2 was used by 69%. An author survey indicated that the authors did not use AMSTAR 2 mostly because they were not aware of it, their protocol was already established, or data collection completed at the time when the new tool was published. Barriers towards AMSTAR 2 use were lack of quantitative assessment, insufficient awareness, length, difficulties with a specific item.ConclusionIn articles published in 2018-2020, that were submitted to a journal after AMSTAR 2 tool was published, almost half of the authors (44%) still used AMSTAR, the old version of the tool. However, the use of AMSTAR has been declining in each subsequent year. Our survey indicated that editors and peer-reviewers did not ask the authors to use the new version of the tool. Few barriers towards using AMSTAR 2 were identified, and thus it is anticipated that the use of the old version of AMSTAR will continue to decline.
