Materials and methods
The purpose of this research was to conduct a retrospective
observational descriptive epidemiological analysis on all instances of
GC that were identified in Saudi Arabia across all regions between
January 2004 and December 2017. Because the information on the GC
incidence in Saudi Arabia is readily available to the scientific
researchers and can be obtained through the SCR reports with little
effort, the observational descriptive epidemiological study that was
conducted did not require any kind of ethical approval. The Saudi
Ministry of Health established a population-based cancer registry in
1992, and its records provided the basis for this investigation.
Furthermore, the first cancer report in Saudi Arabia was issued in 2001,
and the most precise cancer reports in Saudi Arabia were published at
the beginning of 2004. In addition, the most recent information
accessible from the SCR was collected in 2017.
SCR has been issuing reports on the pattern of cancer in Saudi Arabia
since 2001, with the primary purpose of describing the epidemiological
spread of the disease. On the basis of this data, we have access to
in-depth reports for 13 administrative regions, covering the years
2004-2017, that detail the CIR and ASIR, adjusted by province in Saudi
Arabia, patient gender, and year of diagnosis. However, for this study,
all of the information from the SCR was used to collect important data.
Data was analysed using SPSS, the Statistical Package for the Social
Sciences, version 20.0. The descriptive statistics of the
epidemiological data involved computing the overall of percentage, CIR,
and ASIR adjusted by gender, geographical region, and year of diagnosis.
Comparisons of CIR and ASIR of GC between male and female Saudis were
analysed using t-test for independent samples.
Version 20.0 of the Statistical Package for the Social Sciences (SPSS)
was employed in the study of data. The descriptive analysis of the
epidemiological data involved computing the overall percentage, the
age-specific incidence rate (ASR), the CIR, and the ASIR stratified by
gender, geographical region, and year of diagnosis. The independent
sample t-test was performed to compare male and female Saudis’ CIR and
ASIR of GC. In addition, both the CIR and ASIR of GC were analysed
across regions of Saudi Arabia using the Kruskal-Wallis test. However,
the sex ratio for GC was computed from the age-specific incidence rate,
the CIR, and the ASIR in this study.
