Abstract

PURPOSE:

Although the dismal clinical prognosis of diffuse intrinsic pontine glioma (DIPG) has not changed, there has been significant progress in the academic literature made in the biological understanding of this brainstem tumor. The aim of this analysis was to evaluate citation and other bibliometric characteristics of the 100 most-cited DIPG articles in the current literature in order to better understand the current state of our academic efforts in this area.

METHODS:

Elsevier's Scopus database was searched for the 100 most-cited articles that focussed on DIPG. Articles were dichotomized as either primarily basic science (BSc) or clinical (CL) articles. Various bibliometric parameters were summarized and comparison between BSc and CL articles was performed using Pearson's chi-square and Mann-Whitney U tests.

RESULTS:

Of the 100 most-cited articles, 36 (36%) were BSc and 64 (64%) were CL articles. Overall median values were as follows: citation count, 52 (range, 27-261); citation rate per year, 8.6 (range, 1.7-104); number of authors, 9 (range, 1-63); and publication year, 2011 (range, 1997-2017). Articles were published in a total of 43 different journals and predominately originated in the USA (n = 67, 67%). When compared with CL articles, BSc articles reported significantly greater citation count (P = 0.03), citations rate per year (P < 0.01), number of authors (P < 0.01), and more recent years of publication (P < 0.01).

CONCLUSIONS:

The 100 most-cited articles about DIPG were characterized in this analysis. Although smaller in overall proportion, BSc articles demonstrated significantly increased bibliometric parameters, supporting the recent dominance of BSc in this field, primarily involving histone biology of the H3K27M mutation. Moving forward, it will be of great interest to see how the findings of these high-impact BSc articles will translate into future high-impact CL articles.
