Economically
country classification
The economics states
are established among the means of GNI-PPP according the administrations of the
International Monetary Fund (IMF); the World Bank (WB) and the Central
Intelligence Agency (CIA) [13-15]. The difference concerning the same country
can be considerable among the data origin. These variations are explaining by:
·
GNI-PPP
is estimated
·
Anterior
projection of an economic crisis changes GNI-PPP data
·
The
estimation of the population included in the local population
·
The
choice elements for GNI-PPP evaluation have some subjective part.
These data must be
taken with precaution
Economically Country is
divided according to the gross national income (GNI) per capita 2016, Atlas
method and PPP [15].
·
Estimated to be
low income ($1,005 or less)
·
Estimated to
be lower middle income ($1,006 to $3,995)
·
Estimated to
be upper middle income ($3,956 to $12,235)
·
Estimated to
be high income ($12,236 or more).
Gross
national income (GNI), Per capita, Purchasing power parity (PPP)
Gross
national product is gross domestic product (GDP) plus net income (employee
compensation and investment income) from abroad. GNI, per capita is GNI divided
by mid-year population. PPP is purchasing power parity; an international dollar
has the same purchasing power over GNI as a U.S. dollar has in the United
States. PPP exchange rates are used to account for the local prices of goods
and services not traded internationally. However, PPP is used to compare across
national accounts, not for making international poverty comparisons [15].
Cancer
incidence
Incidence is the number
of new cases that occurs during a given period of time in a specified
population. It can be expressed as an absolute number of cases per year or as a
rate per 100,000 persons per year. The rate provides an approximation of the
average risk of developing a cancer. Cancer incidence data presented are based
on the most recent data available at IARC. GLOBOCAN 2012 provides a global
profile of cancer that has been developed using a number of methods that are
dependent on the availability and the accuracy of the data. National sources
are used where possible, with local data and statistical modeling used in their
absence.
Population
Standard population
(POPst) is determining to Senegal population (Western Africa) with 14,668,522
persons. Nepal population is estimated to 29,384,297 persons. Population
compares estimates from the US Bureau of the Census based on statistics from
population censuses, vital statistics registration systems, or sample surveys
pertaining to the recent past and on assumptions about future trends [16].
Provisional
budget (thousands of U.S $)
The World Health
Organization (WHO) emphasizes that, when developing national strategies for
controlling cancer, countries should consider the following four broad
approaches based on their economic development:
·
The primary
prevention
·
The early
detection and secondary prevention
·
The diagnosis
and treatment
·
The palliative
care.
The provisional budget
is establishing among the guidelines developed by WHO for regional and national
cancer control programs according to national economic development. However, an
International Atomic Energy Agency report suggested that in developing
countries at least 60% of cancer patients require radiation treatment.
Radiotherapy is one of the main components of modern cancer treatment and
requires substantial capital investment, trained professionals in several
disciplines, high precision equipment and a particular external and internal
organizational structure [17]. In High Incomes Countries, the healthcare costs
can be as much as 8.4% (UK in 2007) to 18% (USA in 2009) of a country’s gross
domestic product [18]. Cancer consumes about 5-10% of the global healthcare
budget, of which radiotherapy only consumes about 5%; thus, more than 50% of
cancer patients requiring radiotherapy in low and middle-income countries lack
access to treatment [19]. A benchmark of between 400 and 500 patients per
treatment unit per year has been used to calculate machine throughput in
several reports [20,21]. The benchmark of 450 patients per machine, which
corresponds to about 8 operating hours per day, seems adequate for High Incomes
Countries. For scenarios where radiotherapy demand is not satisfied, a
treatment day of 10 h optimizes the utilization of equipment and decreases the
number of machines needed. But, the range of needs currently covered varies
from 0% and 3-4% in Low Incomes Countries in Latin America and Africa up to
59-79% in Up-Middle Incomes Countries in Europe-Central and Asia [22]. However,
in this study, in order to found the best cost-effective methods to prevent and
treat cancer, the number of machines needs is establishing among 3 millions of
peoples and not by the number of cancer cases, according to the weakness of the
countries incomes.
Standard
budget for 5 years (S0)
Standard budget
for 5 years (S0) is estimated using a population of 1,000,000
persons in Senegal (POPst). Senegal has 8361 new cancer cases (CIst) in 2015
with a means GNI-PPPst of US$ 2,551 referred to the year 2016 (low middle
income country), according the administrations of the International Monetary
Fund (IMF); the World Bank (WB) and the Central Intelligence Agency (CIA).
Estimation budget is taken into account the weakness of the countries incomes.
Standardized
rapport (R0)
Standardized rapport (R0),
among the GNI-PPP, CI and the number of the population, is calculated.
Standardization simplifies comparisons of GNI-PPP and cancer incidence rates
among populations.

Note:
For Radiotherapy equipment, R0 = GNI-PPP X POP / GNI-PPPst X 3 million peoples;
Senegal has installed two new radiotherapy machines in 2017. Radiotherapy
equipment is estimated to US$ 2,500,000.
For Prevention and
screening infrastructure, R0 =GNI-PPPX POP / GNI-PPPst X 3 million peoples.
