Introduction: Our safety net hospital offers minimally
invasive, traditional open and perineal radical
prostatectomies, as well as radiation therapy and medical
oncological services when appropriate. Historically,
only few African American and Hispanic patients
elected surgical procedures due to unknown reasons.
Interestingly, after initiation of the prostate cryoablation
program (Whole Gland) in 2003 at Denver Health Medical
Center (DHMC) we noticed a trend towards cryotherapy
in these speciic patient populations for the treatment of
localized prostate cancer. We analyzed the proile of ethnic
minority men evaluated for localized prostate cancer and
evaluated the associated factors in the decision making for
the treatment of localized prostate cancer.
Materials and methods: A retrospective review of 524
patients seen for prostate cancer from January 2003 to
January 2012 in our safety net hospital was conducted. The
treatment selected by the patient after oncologic consultation
was then recorded. The health insurance status, demographic
data, and personal statements of reasons for elected procedure
were obtained. A multivariate logistic regression for
associated factors inluencing treatment decisions was then
formed. Patients were categorized by using the D’Amico
risk stratiication criteria.
Results: The insurance status revealed that only 1% of
African American patients had private health insurance
versus 5% Hispanic and 26% of Caucasians. African
American men were at higher D’Amico risk with more
positive metastasis evaluation yet were less likely to
undergo surgery and instead often elected for radiation
therapy. Conversely, Hispanic and Caucasian men
often elected cryoablation and radical prostatectomy for
their treatment. Referrals for surgery were primarily
Caucasian males with private health insurance. Most
minority patients had indigent health coverage. Statistical
analysis further revealed that age, marital status, indigent
enrollment, D’Amico risk, and the option of cryoablation
may inluence patient’s selection for surgical management
of localized prostate cancer.
Conclusion: Many factors inluence treatment selection
including race, age, marital status, enrollment in an
indigent program, and a high D’Amico risk. The less
invasive nature of cryoablation appeared to inluence
patients’ opinion regarding surgery for the treatment of
localized prostate cancer, especially in African American
men.
Key Words: prostate cancer, minority group,
decision making, cryoablation
higher risk of being diagnosed, and have a 2-3 times
higher risk of dying of prostate cancer compared to
Caucasian men.

Moreover, African American men
have lower odds of undergoing radical prostatectomy
compared to Caucasian men.

Conversely, they have
greater odds of receiving radiation therapy or watchful
waiting.

According to the Ofice of Minority Health
of the US Department of Health Human Services, new
prostate cancer diagnosis in Hispanic males occurs in
116.2 cases out of every 10 men.

Prostate cancer exhibits the most striking racial
disparity, as African American men are at 1.4 times
