Author Information
Author(s): Wallis S Plummer, Premini Persaud, Penelope J Layne
Primary Institution: The Cancer Registry of Guyana
Hypothesis
What are the ethnic trends in cancer prevalence among the population of Guyana?
Conclusion
The Cancer Registry of Guyana shows a high incidence of prostate, cervical, and breast cancers among Afro-Guyanese, indicating the need for further investigation into socio-economic, dietary, and genetic influences.
Supporting Evidence
- Afro-Guyanese men accounted for over 65% of prostate cancers.
- Indo-Guyanese women had the highest cases of breast cancer at 45%.
- Cervical cancer was significantly more common among Indigenous Amerindian women.
Takeaway
This study looked at cancer cases in Guyana and found that different ethnic groups have different rates of certain cancers, especially among Afro-Guyanese.
Methodology
A comprehensive review of the Cancer Registry's database was conducted, focusing on ethnic and site prevalence of major cancers, with chi squared analysis applied.
Potential Biases
Potential bias due to the absence of a Cancer Act and reliance on data from public and private health facilities.
Limitations
The study may not capture undiagnosed cases and deaths due to cancer that were not managed by a healthcare worker.
Participant Demographics
The population of Guyana is 44% East Indian, 30% African, and 9% Indigenous Amerindian.
