Among patients with at least two years of follow up after external beam radiation therapy, three- and five-year PSA-failure free survival was 73.8 percent and 65.1 percent respectively. In the U.S., those percentages are 90 percent and 85 percent, respectively.
Reasons recognized by KBTH clinicians for patients declining radiation therapy included: the prohibitive cost of treatment, fear of radiation, and a state of denial based on their perception of disease originating solely from spiritual causes rather than biologic processes.
The data, which to date provides the largest source of published information on outcomes for prostate cancer treatment in the West African region, is a call to action, according to the authors.
The research team plans to develop treatment regimens tailored to the needs of Ghanaian men, which may differ from guidelines currently utilized in the Unites States and Europe in order to better address the disease burden and improve mortality rates in Ghana. That could mean more frequent PSA screening.
"There is controversy in the United States with PSA testing, but in a country like Ghana, there may be a role for PSA screening, even infrequent screening, because of all the late stage cancers we are finding," said Dr. Yamoah.
The team has established collaboration between two institutions with the hope of improving prostate cancer treatment and plan to start more clinical trials to develop novel, shorter course treatments for locally-advanced prostate cancer.
"Based on these results, our group has proposed a plan for future research aimed at identifying an appropriate role for PSA screening in this population, developing radiation therapy treatment schedules that better fulfill the needs of Ghanaian prostat
