Trends in hepatocellular carcinoma research from 2008 to 2017: a bibliometric analysis

Abstract

ObjectivesTo comprehensively analyse the global scientific outputs of hepatocellular carcinoma (HCC) research.MethodsData of publications were downloaded from the Web of Science Core Collection. We used CiteSpace IV and Excel 2016 to analyse literature information, including journals, countries/regions, institutes, authors, citation reports and research frontiers.ResultsUntil March 31, 2018, a total of 24,331 papers in HCC research were identified as published between 2008 and 2017. Oncotarget published the most papers. China contributed the most publications and the United States occupied leading positions in H-index value and the number of ESI top papers. Llovet JM owned the highest co-citations. The keyword “transarterial chemoembolization” ranked first in the research front-line.ConclusionsThe amount of papers published in HCC research has kept increasing since 2008. China showed vast progress in HCC research, but the United States was still the dominant country. Transarterial chemoembolization, epithelial-mesenchymal transition, and cancer stem cell were the latest research frontiers and should be paid more attention.

Knowledge Mapping of Angelica sinensis (Oliv.) Diels (Danggui) Research: A Scientometric Study

“…The IF of the journals publishing AS research ranged from 1.984 (Evidence-Based Complementary and Alternative Medicine) to 6.044 (Carbohydrate Polymers). As is shown in Figure 2, the dual-map overlay of journals represents the subject distribution of journals, with the left side of the graph representing citing journals, the right side of the graph indicating cited journals, and the colored lines representing the citation relationship between articles in citing journals and articles in cited journals (Chen, 2017;Miao et al, 2018). We found that there were three citation paths, including two orange paths and one yellow path.…”

“…The top 10 references with the strongest strength citation burst identified by CiteSpace are presented in Figure 5. Papers with a high citation burst are paid much attention by peers in the scientific community, therefore emerging trends or topics within the AS research field were labeled in this study by AS publications with high citation bursts (Chen, 2017;Miao et al, 2018). Overall, the burst strength of the top 10 AS publications ranged from 2.5479 to 3.9294, while endurance strength ranged from 4 to 6 years, as indicated by the number of red squares.…”

“…Scientometric analysis is a method that has been widely employed to analyze research frontiers and development trends of unique research fields or subjects (Xiao et al, 2017;Miao et al, 2018;Chen et al, 2019;Lu et al, 2019). For example, Xiao et al (2017) employed this method to study organic photovoltaic technology (OPV) and found that the emerging trends of OPV research included inverted device structure and tandem solar cells.…”

“…For example, Xiao et al (2017) employed this method to study organic photovoltaic technology (OPV) and found that the emerging trends of OPV research included inverted device structure and tandem solar cells. Miao et al (2018) applied this method to analyze hepatocellular carcinoma (HCC) research and found that transarterial chemoembolization, cancer stem cells and the epithelial-mesenchymal transition are the major research foci of HCC. In a published work, we analyzed the top 100 mostcited publications related to network pharmacology (NP), and found that NP focused on cardiovascular diseases and cancers (Lu et al, 2019).…”

On the challenges ahead of spatial scientometrics focusing on the city level

“…Parallel with the globalization of science, spatial scientometric studies have become more common. As demonstrated by Frenken et al (2009a), spatial scientometrics initially involved the country level in the research focusthe works performed by Narin and Carpenter (1975) and Frame et al (1977) are considered particularly important in the fieldand the majority of spatial scientometric studies have still been focusing on examining the country level (see, for example, Almeida et al 2009;Gazni et al 2012;Glänzel 2001;Horta and Veloso 2007;Lee et al 2011;Leydesdorff et al 2014;Miao et al 2018;OECD and CSIC 2016;Stephan and Levin 2001;Wang et al 2017). Besides country-level scientometric analyses, based on experiences gained from them, many spatial scientometric studies have been carried out with sublevel territorial units (e.g., federal states, provinces, and NUTS regions 1 ) in focus.…”
