Abstract
Background
Despite its impact on female
health worldwide, no efforts have been made to depict the global
architecture of ovarian cancer research and to understand the trends in
the related literature. Hence, it was the objective of this study to
assess the global scientific performance chronologically, geographically
and in regards to economic benchmarks using bibliometric tools and
density equalizing map projections.
Methods
The NewQIS platform was
employed to identify all ovarian cancer related articles published in
the Web of Science since 1900. The items were analyzed regarding
quantitative aspects (e.g. publication date, country of origin) and
parameters describing the recognition of the work by the scientific
community (e.g. citation rates).
Results
23,378 articles on ovarian
cancer were analyzed. The USA had the highest activity of ovarian cancer
research with a total of n = 9312 ovarian cancer-specific publications,
followed by the UK (n = 1900), China (n = 1813), Germany (n = 1717) and
Japan (n = 1673). Ovarian cancer-specific country h-index also showed a
leading position of the USA with an h-index (HI) of 207, followed by
the UK (HI = 122), Canada (HI = 99), Italy (HI = 97), Germany (HI = 84),
and Japan (HI = 81).
In the socio-economic analysis, the USA were
ranked first with an average of 175.6 ovarian cancer-related
publications per GDP per capita in 1000 US-$, followed by Italy with an
index level of 46.85, the UK with 45.48, and Japan with 43.3. Overall,
the USA and Western European nations, China and Japan constituted the
scientific power players publishing the majority of highly cited ovarian
cancer-related articles and dominated international collaborative
efforts. African, Asian and South American countries played almost no
visible role in the scientific community.
Conclusions
The quantity and scientific
recognition of publications related to ovarian cancer are continuously
increasing. The research endeavors in the field are concentrated in
high-income countries with no involvement of lower-resource nations.
Hence, worldwide collaborative efforts with the aim to exchange
epidemiologic data, resources and knowledge have to be strengthened in
the future to successfully alleviate the global burden related to
ovarian cancer.
