Abstract: AIM: To determine the growth rule and tendency of retinoblastoma 
(Rb) literature, and to provide the basis for research of diagnosis, treatment 
and on Rb.
METHODS: Bibliometric analyses were carried out on Rb literatures which 
contain the descriptors of Rb in their titles or texts from 1929 to 2010 in 
PubMed database (www.ncbi.nlm. nih.gov/Pubmed). The biomedical journals 
referring to Rb by using bibliometric indicators were calculated. The principal 
bibliometric indicators, i.e, Price's and Bradford's laws to the increase or 
distribution of scientific literature, the participation index of languages and the 
journals were applied. By means of manual coding, Rb documents were 
classified according to documents studied and to statistical analysis.
RESULTS: During 1929-2010, there were 16162 literatures in the PubMed 
database including the word Rb. According to the literature type, it includes 
Review (n=2026), Randomized Controlled Trial (n = 7), Practice guideline (n = 
3), meta-analysis (n = 4), letter (n = 215), editorial (n = 98), clinical trial (n = 
115) and others (n = 13694). By the statistical analysis, its equation is near 
power index (y = 3.0477 x(2.6088), R-2 = 0.9666). From 1929 to 2010, Rb 
literatures in English were primarily dominant (90.71%) and the amount of the 
literature in Chinese ranked the fourth (1.37%). By searching PubMed, 1420 
(8.8%) literatures covered were from 41 of 48 ophthalmological, and 406 
(2.5%) literatures from 44 of 86 pediatrics journals that correlated with 
retinoblastoma (SCI-indexed). The data showed that the literatures of Rb were 
gradually increasing year by year and were approximate near power index 
during 1929-2010, and the document publishes published mainly in 
ophthalmological journals, and in English (90.71%), and showing that the study 
on Rb is a popular subject in the last half century.
CONCLUSION: The literatures of Rb are gradually increasing, mainly English in 
ophthalmologic journals.
