INTRODUCTION
Cancer starts when cells in the body change (mutate) and grow out of control. Your body is
made up of tiny building blocks called cells. Normal cells grow when your body needs them.
They die when your body doesn't need them anymore. Cancer is made up of abnormal cells
that grow even though your body doesn‟t need them. In most types of cancers, the abnormal
cells grow to form a lump or mass called a tumor. Leukemia is different from most other
cancers. Leukemia cells don't always form a tumor. This cancer starts in the bone marrow.
The bone marrow is the thick, spongy liquid inside your bones. It's where new blood cells are
made. Leukemia starts in early forms of blood cells, often white blood cells, which help fight
infections. When you have leukemia, your body makes too many "bad" blood cells that don‟t
work like they should. Instead of forming tumors, leukemia cells travel in the blood and go
all over the body. This means they can reach almost any organ. Leukemia can cause problems
and be found in many different ways, depending on which organs are affected.
Blood is made up of liquid, called plasma, and 3 main kinds of cells. Each kind of cell has a
special task: White blood cells. These help the body fight infection and disease. Red blood
cells. These carry oxygen from the lungs to the body's tissues and carry carbon dioxide from
the tissues to the lungs. Platelets. These help form blood clots and control bleeding. Blood
cells are made in the soft center of the bones called the bone marrow. In adults, active bone
marrow is found mostly in the hip bones, ribs, spine, and skull. Normal cells in the bone
marrow develop from very immature cells into mature, working cells ready to go out in the
blood. Early, less mature, non-working forms of new blood cells are called blasts. As cells
mature in the bone marrow, they become smaller and more compact. They're better able to do
their special jobs. Some new blood cells stay in the bone marrow to grow, while others move
to other parts of the body to grow. More blood cells are made when the body needs them,
such as when a person has an infection or low numbers of red blood cells (anemia). This
process keeps the body healthy.[1]

Scientometric Study
Scientometric is a study to measure the performance of researchers as well as the research
publications. The research activities contain major changes over the last few decades and
emerged as an established research in the discipline of “Library and Information Science”.
The study of scientific literature has a long history dating back to the early decades of the
past century. However, despite in the number of research literature in this area it was not until
1969, that the term bibliometrics first appeared in print (Pritchard 1969).[2] Definition of
bibliometric was „application of mathematical and statistical methods to books and other
media of communication‟, particularly in North America, the term was quickly adopted and
used (Wilson, 1999).[3] At the same time, Nalimov and Mulchenko (1969)[4] coined the term
scientometrics to refer to „the application of quantitative methods which are dealing with the
analysis of science viewed as an information process‟. In contrast, this term was widely used
in Europe (Wolfram, 2003).[5] Initially, therefore, scientometrics was restricted to the
measurement of science communication, whereas bibliometrics was designed to deal with
more general information processes, Andres A (2009).[6]
Review of Literature
Jose Luis Martin Perez-Santos and Maricruz Anaya-Ruiz (2013)7 Mexican breast cancer
research output, 2003-2012. The objective of this study was to explore a bibliometric
approach to quantitatively assess current research trends with regard to breast cancer in
Mexico. Data were retrieved from the Web of Science database from 2003 to 2012; A total of
256 articles were retrieved. The institutions with the majority of publications were the
National Autonomous University of Mexico (22.3%), the National Institute of Cancerology
(21.9%), and the Social Security Mexican Institute (20.3%); clinical observation studies were
the dominant investigation type (64%), and the main types of research were metabolics
(24.2%) and pathology (21.5%). This article demonstrates the usefulness of bibliometrics to
address key evaluation questions and establish priorities, define future areas of research, and
develop breast cancer control strategies in Mexico.
Alí Ruiz-Coronel et al (2020)[8] National Cancer Institute scientific production scientometric
analysis, the using the LabSOM software and the ViBlioSOM methodology based on
artificial neural networks, the INC a scientific production indexed in the Web of Science
from 2007 to 2017 was analyzed. The multidimensional scientometric profile of the Institute
was obtained and compared with that of other national health institutions. In terms of
Ravichandran et al. World Journal of Engineering Research and Technology

productivity, INC ranks fourth among the 10 Mexican public health institutions indexed in
the Web of Science; in the normalized impact ranking, it ranks sixth. Although out of 1323
articles 683 (51.62 %) did not receive citations, 11 articles classified as excellent (0.83 %)
obtained 24 % of 11,932 citations and, consequently, INC a normalized impact rate showed
mean productivity higher than the world mean.
Jeyshankar and Ramesh babu (2013)[9] examined the scientometric analysis of leukemia
research output (1960-2011): an Indian perspective. The data was collected from the Scopus
database. The leukemia research output from India a total of 2120 research papers were
published during the period 1960-to 2011. The growth rate is found to be at a maximum
during the period 1992-1996 and the minimum during the period 1982-1986. The average
growth rate works out to be 1.12 and Dt is in a fluctuation trend. The largest number (1524)
of the journal articles 97.89%) used for publication indicates a continued trend of relying
primarily on this form of publication. The future trend of leukemia will have an increasing
trend in the year 2015 and may gain an increasing trend in 2020. A single-authored
publication from form 6.37% and the average degree of collaboration the 0.96. The Journal of
leukemia ranks first with 6.37%.
Rabiya Mushtaq & Fayaz Ahmad Loan (2021)[10] examined the lung cancer research in
India and Iran: The top 10 countries contribute 89.77% of the total research productivity in a
scientometric study. The lung cancer 151,903 (35.75%) publication productivity of the USA.
the RGR is found to exhibit the highest value of 0.71 and the lowest of 0.10. Year-wise
calculated values of RGR for India depict that year 1989 has the highest RGR of 0.71
however, later shows a decreasing trend dipping as low as 0.10 for the years 1998 and 2000.
Both countries very high of the degree of collaboration in (0.98 for Iran and 0.97 for India).
The value of the collaboration coefficient (CC) is above 0.50, i.e. (0.89 for India and 0.91 for
Iran). This also confirms that both nations prefer multiple authorship patterns.
Sudhakar and Thanuskodi (2018)[11] analyzed the scientometric analysis of Marine
Pollution Bulletin Journal research publications from 2008 to 2017 with 5416 publications.
Maximum numbers of 905(16.71%) publications are contributed in the year 2017. This study
identified RGR has been decreased from 0.63 to 0.18 and the same time doubling time has
been increased from 1.10 to 3.85. The degree of collaboration was 0.94, which clearly
indicates its dominance of multiple author‟s contributions. Liu J. was the top ranked authors

Data Analysis and Interpretations
Compound Annual Growth Rate [CAGR]
The Compound Annual Growth Rate [CAGR] is one of the useful measures to identify the
growth, over the multiple time periods. It can be measure from the initial number of
publications to ending number of publications. The mathematical formula of CAGR is used
Ashok Kumar and Gopala Krishnan (2013)[16]
The compound annual growth rate was calculated by the following formula,
-1
Ravichandran et al. World Journal of Engineering Research and Technology

101
During the ten year study period compound annual growth rate is calculated by the Leukemia
research outputs in India from the beginning year and ending year. It is identified from the
table 1 the compound annual growth rate is 5.37.
Relative Citation Index (RCI)
Relative citation index (RCI) was developed by the Institute of Scientific Information and
examine the impact of different countries, institutions, authors and journals research
publications. The scientific impact of leading countries was examined by using two relative
indicators, namely citations per paper (CPP) and relative citations index (RCI). Citations per
paper (CPP) are a relative indicator computed as the average number of citation per paper.
To measure the both influence and visibility of a country research, the following formula has
been used by Bharvi Dutt and Khaiser Nikam (2016).[17]
RCI = 1 indicate that a country‟s citation rate is equal to the world citation rate
RCI > 1 indicate that a country‟s citation rate is greater than the world citation rate
RCI < 1 indicate that a country‟s citation rate is lower than the world citation rate
H-Index
Hirsch (2005)[18] proposed the h-index is one of the alternatives to the standard bibliometric
indicators for single scientists, it is defined below the table,
A scientist has index h if h of his or her Np papers have at least h citations each and other
papers (Np – h) have ≤ citations each.
Ye (2009)[19] found that the Glanzel-Schubert (2007)[20] model was better than the Hirsch
and Egghe-Rousseau (2006)[21] model to estimate the h-index of countries and other units.
Gupta and Bala (2013)[21] discussed the h-index in the various acts of Epilepsy research in
India. Differences among the various models of the h-index are

The year –wise growth of leukemia research publications during the 10 years study period in
the table-1 between 2011 and 2020 with 5,474 research publications and 86,869 citations.
The study from the maximum of 692 (12.64%) research publications are contributed in the
year 2020, followed by 600 (10.96%) publications in the year 2016, and 575 (10.50%)
publications in the year 2019. The average research publication per year is 547.4.
During the ten-year study that a total number of 5,474 publications are received 86,869
citations. Out of that maximum of 26,325 (30.30%), citations are received 552 publications in
the year 2015. Followed by 12,682 (14.60%) citations are received 533 publications in the
year 2017. From the study, out of 5,474 publications, 4,228 (100%) research publications are
cited publications, and 1,246 (100%) research publications are uncited publications. The
maximum of citation per paper is 47.69 in the year 2015, followed by CPP is 23.79 in the
year 2017, and by CPP is 22.16 in the year 2011 and the average citation per paper is 1.66.
The maximum of RCI is 3.01 in the year 2015, followed by 1.50 in the year 2017, by 1.40 in
the year 2011 and the average RCI is 1.04.
Relative Growth Rate (RGR)
The most important feature of science and technology in recent years has been calculated by
the rate of growth. Scientific growth has been involved not only increase in manpower and
financial investment. The relative growth rate is identified by the increase in number of
publications per unit of time. The mean relative growth rate over the particular period of
interval can be calculated in the following formula developed by Mahapatra (1985).[23]
Ravichandran et al. World Journal of Engineering Research and Technology
www.wjert.org ISO 9001: 2015 Certified Journal
103
Where,
R (a) = RGR = the mean relative growth rate over the specific period of interval
W1 = the logarithm of beginning number of publications/pages
W2= the logarithm of ending number of publications/pages after a specific period of interval
T2 – T1 = the unit difference between the beginning time and the ending time.
The doubling time is the time taken for the doubling of the number of records actually
published within a stipulated period. The doubling time is calculated from the relative growth
rate and the natural logarithm number is used, the difference has a value of 0.693. The
corresponding doubling time can be calculated by the following formula,

authorship mode with 1,064 (19.44%) publications, three authorship mode with 885 (16.17%)
publications. During the study period five authors are contributed with 739(13.50%)
publications, two authors are contributed only 696 (12.71%) publications. single author are
contributed only 180(3.29%) publications. This study confirmed that more than 97% of
publications are contributed in multiple authors.
Degree of Collaboration
The degree of collaboration is relationship between the single author and multi author‟s
contributions. The degree of collaboration is calculated by the Subramanian formula
(1983)[24], used by Vivekanandhan (2016),[25] Sivasamy (2020).[26] Ravichandran
(2021)[27]
Nm = Number of multi authored publications
Ns = Number of single authored publications
The present study of number of multi- authors = 5294, number of single author = 180
The degree of collaboration is =5294/ (180+5294) = 0.97

The leukemia research publications in India table -5 shows that the degree of collaboration
ten years study period to selected. The degree of collaboration from the study it is identified
that is between 0.96 in the year 2011 and 0.96 in the year 2020. The degree of collaboration
average is 0.97. The majority from this study it is identified that, the leukemia research
publications are contributed by collaborated authors.
Collaborative Coefficient (CC)
The pattern of co-authorship collaboration among the authors can be measured with the
following formula suggested by Ajiferuke, et al. (1988).[28]
Whereas,
Fj = Number of publications with j author papers
N = Total number of the research publications and
k = the greatest number of authors/ paper in the given field.
Collaboration Index (CI)
The simple indicator are presently employed in the publications to the collaboration index,
which is to be understand nearly as the mean number of authors per paper are suggested by
Ajiferuke, et al.(1988)[28]
Ravichandran et al. World Journal of Engineering Research and Technology
www.wjert.org ISO 9001: 2015 Certified Journal
106
Here
J - The number of co-authored papers appearing in a discipline
N - The total number of publications in the field over the same time period of interval and
k - The highest number of authors per paper in a same time field.
Modified Collaboration Coefficient
The modified collaboration coefficient (MCC) counted by the formula which is suggested by
Savanur and Srikanth, (2010)[29]
Which is given below:
Where,
j = the number authors in an article i.e. 1, 2, 3......
Fj = the number of j authored articles
N = the total number of articles published in a year, and
A = the total number of authors per articles

in the year 2011. The average CC value is 0.76. The CI values are identified from the table-6,
the maximum of CC value is 4.44 in the year 2017 and a minimum of CI value is 4.02 in the
year 2011.The average CI value 4.30. The maximum of MCC value is 4.47, and a minimum
of MCC value is 4.03. The average MCC value is 4.32.
Co-authorship Index (CAI)
To study how the pattern of co-authorship and the use of co-authorship index suggested by
Garg and Padhi (2001)30 has been explained the under mentioned formula. To evaluate the
co-authorship index (CAI) is the whole set of data is divided into 2 block years.
Whereas,
Nij - Number of publications having j authors in i block
Nio - Total publications of i block
Noj - Number of publications having j authors for all blocks
Noo-: Total number of publications for all authors and the all blocks
Here CAI=100 implies that a country‟s co-authorship effort for a particular authorship
correspond to the world average
CAI > 100 reflects higher than average co-authorship effort
CAI < 100 reflects lower than average co-authorship effort by the given type of authorship
pattern.
For calculating the co-authorship index for authors, years have been replaced into block
years. For this study, the authors have been classified into two blocks (ie.2010-2014 and
2015-2019) Vs. Single, Two, Three authors and More than 3 authors.

A straight – line equation is adapted to measure the future value based on previous data. The
time series analysis study reveals that, the estimated growth values are identified based on
previous data. Time series analysis used by Jeyshankar and Ramesh babu (2013).[31]
This study identified the future prediction of Leukemia research publications in India for the
year 2025 and 2030.
Straight Line Equation is
Y = a + bx
Here,
∑Y = 5474, ∑X2 = 110, ∑XY = 2029
a= ∑Y/N = 5474/10 = 547.4 = 547
b= ∑XY/ ∑X2 = 2029/110 = 18.4 = 18
The growth of estimate publications in the year 2025 is, when x = 2025-2015 = 10
Y = a + bx
= 547+ (110*10) = 547+1100 = 1647
The growth of estimate publications in the year 2030 is, when x = 2030-2015 = 15
Y = a + bx
= 547 + (110*15) = 547 + 1650 = 2197
The estimated growth based on a time series analysis statistical application will be expected
in the Leukemia research publications in Indian in the year 2025 is around are equal to 1647
publications and the year 2030 is around are equal to 2197 publications. So that time serious
analysis study conformed Leukemia research publications in India is increasing trend.
