SCIENTOMETRIC ANALYSIS OF “ANNALS OF ONCOLOGY” DURING 2010 – 2014

This paper presents bibliometric analyses of 10681 articles published in ANNALS OF ONCOLOGY (AOO) during 2010-2014. The data was downloaded from web of science database. The analysis covers various parameters like year wise publication, growth pattern, word frequency, ranking of authors, ranking of institution, document types etc., and Histographicanalysis of the datasets has been performed using Histcite software.


INTRODUCTION
Academic journals are utilized by the researchers and experts to share their thoughts, considerations, developments, advancements, and disclosures. So individual journals are the main target of the many bibliometric and scientometric studies. The terms bibliometrics and scientrometrics wereintroduced by Pritchard, Nalimov and Mulchenko in 1969. Bibliometric study is a simple statistic method of bibliography counting to evaluate and quantify the growth of a subject (Tsay et al., 1997).

ORIGIN OF THE JOURNAL
Annals of Oncology, the journal of the European Society of Medical Oncology and the Japanese Society of Medical Oncology, provides rapid and efficient peer-review publications on innovative cancer treatments or translational work related to oncology and precision medicine.
Main focuses of interest include: systemic anticancer therapy (with specific interest on molecular targeted agents and new immune therapies), randomized trials (including negatives ones), top-level guidelines, and new fields currently emerging as key components of personalized medicine, such as molecular pathology, bioinformatics, modern statistics, and biotechnologies.
Radiotherapy, surgery and pediatrics manuscripts can be considered if they display a clear interaction with one of the fields above or are paradigm-shifting.
With a large international editorial board of experts who are leaders in their fields, Annals of Oncology aims at delivering the best communication on the fast moving, and continually evolving, global oncology landscape.

REVIEW OF LITERATURE
There are several bibliometric studies available in the literature which includes bibliometric studies on single journals, citation studies and subject studies. A study by Nageswara Rao et al. (2013) on Bibliometric Analysis of theJournal of Propulsion andPower (1985-2013) showed thatthe highest number (194) articles were published in year 1992 and lowest (81) in 1987. Out of total articles, 1330 were produced by two authors and 1098 by three authors. It is found that 1205 different institutions were involved in publication of articles. 'Purdue University' contributed highest number of 163 articles. Out of ranked list of 21 affiliations which produced more than 50 articles, 18 institutions were from USA, 2 from Japan, and 1 from Germany, etc. The required bibliographic data have been captured from Web of Science database and analyzed by using Histcite software application. For each articles we identified like year wise publication, growth pattern, word frequency, ranking of authors, ranking of institution, the country of publication and document types. Contributed most number of articles. One fourth of the total articles published in Pramana are from outside India, the host country of the journal and the number of articles submitting from other countries is also increasing. Cosmology; super symmetry; chaos; quantum chromo dynamics; phase transition; and quark-gluon plasma are the leading micro-fields of physics to which maximum number of articles published in Pramana. The average number of references per article is found as 21.85 and it is 104.4 when the average is taken only for review articles.

OBJECTIVES
The objectives of this study are as follows:  To find out the year wise publication of research output.
 To analysis the growth rate of the publication using CARG, RGR and Doubling Time.
 To find out the ranking of authors and Institutions.
 To examine the contribution of different countries.
 To analysis the document type of the journal.
 To identity keyword frequency of the journal.

ANALYSIS
The bibliographic records for the analysis are limited to 10681 articles published in ANNALS OF ONCOLOGY (AOO)in the period of 2010-2014.

COMPOUND ANNUAL GROWTH RATE -CARG
The Compound Annual Growth Rate (CAGR) (http://www.investopedia.com/terms/c/cagr.asp (11-01-2016)) is the mean annual growth rate of an investment over a specified period of time longer than one year. This can be written as follows: Year Therefore the compound annual growth rate for the period of 5 years is -13.21% field of Botany (Hunt, 1978), which in turn, had its origin from the study of the rate of interest in the financial investment (Blackman, 1919).The mean Relative Growth Rate(R) over the specific period of interval can be calculated from the following equation:

RELATIVE GROWTH RATE (RGR) AND DOUBLING TIME
Where:      It is clearly seen from the table that Van Cutsem E has published the maximum number of articles with 80 records, having the global citation score of 708 and local citation score of 16, followed by Nakagawa K and Yamamoto N with 74 records, having global citation scores of 50 and 70, local citation scores of 3 respectively. It is also noted that La Vecchia C with 55 records has a global citation score of 1451. bbreviatedlist of keywords ccurrence in the records en from the table that the sed in 5590 records by the itation score of 25902 and 12, followed by the word Table 4 shows highly prolific organizations contributing more than 100 articles.From Table 4, it is evident that Institute Gustave Roussy (World's leading cancer-research institutes) contributed highest articles 333 with global citation score of 2644 and local citation score of 124, followed byThe University of Texas: MD Anderson Cancer Center (The original three comprehensive cancer centersin the United States) with 240 articles, having a global citation score of 1752 and local citation score 53 and 213 articles by National Cancer Centre and so on. The data presented in Table 5 which gives the types of articles wise distribution of publication and their citation information. It is clearly noticed from the table that the major source of records published in the form of meeting abstracts (75.11%), followed by articles and letter with 1983 (18.57%) and 267 (2.5%) having global citation scores of 35229 and 845, local citation scores of 1047 and 41 respectively. Hence, It is observed that 'USA' contributed 2039 articlesto the total contributions, followed by 1753 articles by Japan, 1507 articles by Italy and so on.

The doubling time is highest in the year 2013 with 5.77 and lowest in the year 2012 with 1.19.Although this study has identified a decreasing trend of Compound Annual Growth Rate (CAGR), the editorial board should pay much attention to increase it further.
