Abstract
IntroductionAfrican-American black men race is one of non-modifiable risk factors confirmed for prostate cancer. Many studies have been done in USA among African- American population to evaluate prostate cancer disparities. Compared to the USA very few data are available for prostate cancer in Sub-Saharan African countries. The objective of this study was to describe incident prostate cancer (PC) diagnosis characteristics in Burkina Faso (West Africa).MethodsWe performed a prospective non randomized patient’s cohort study of new prostate cancer cases diagnosed by histological analysis of transrectal prostate biopsies in Burkina Faso. Study participants included 166 patients recruited at the urology division of the university hospital of Ouagadougou. Age of the patients, clinical symptoms, digital rectal examination (DRE) result, serum prostate-specific antigen (PSA) level, histological characteristics and TNM classification were taking in account in this study.Results166 transrectal prostate biopsies (TRPB) were performed based on high PSA level or abnormal DRE. The prostate cancer rate on those TRPB was 63, 8 % (n=106). The mean age of the patients was 71, 5 years (52 to 86). Urinary retention was the first clinical patterns of reference in our institution (55, 7 %, n = 59). Most patients, 56, 6 % (n = 60) had a serum PSA level over than 100 ng/ml. All the patients had adenocarcinoma on histological study of prostate biopsy cores. The majority of cases (54, 7 % n = 58) had Gleason score equal or higher than 7.ConclusionProstate cancer is diagnosed at later stages in our country. Very high serum PSA level and poorly differentiated tumors are the two major characteristics of PC at the time of diagnosis.
Highlights
African-American black men race is one of non-modifiable risk factors confirmed for prostate cancer
African-Americans have more advanced stages of PC at diagnosis and higher mortality rates for PC than whites. [1,2,3,4] There is no scientific proof that PC in AfricanAmericans has the same characteristics in their ancestry from Central and West Africa but there is documented evidence in the literature indicating that prostate cancer in one West African country, Nigeria, is similar to rates found in the United States [5]
One hundred and sixty six (166) transrectal prostate biopsies (TRPB) were performed based on high prostate-specific antigen (PSA) level or abnormal digital rectal examination (DRE)
Summary
African-American black men race is one of non-modifiable risk factors confirmed for prostate cancer. Compared to the USA very few data are available for prostate cancer in Sub-Saharan African countries. The objective of this study was to describe incident prostate cancer (PC) diagnosis characteristics in Burkina Faso (West Africa). Many studies have been done in USA among African-American to evaluate prostate cancer disparities in this population. Compared to the USA very few data are available for prostate cancer in Sub-Saharan. This work aims to contribute by providing more data about PC in West Africa and to participate in the research to reduce prostate cancer disparities in black men. The objective of the study was to describe PC diagnosis characteristics at the time of diagnosis in our country
