High Coffee Intake Lowers Risk of Prostate Cancer Recurrence
Pre-Diagnosis Coffee Intake Tied to Prostate CA Outcomes
(HealthDay News) -- Higher coffee consumption before prostate cancer diagnosis is associated with a lower risk of recurrence/progression, according to a study published in the August issue of Cancer Causes & Control.
To examine the correlation between pre-diagnostic coffee and tea consumption and the risk of prostate cancer recurrence/progression, Milan S. Geybels, from Maastricht University in the Netherlands, and colleagues assessed the usual pattern of coffee and tea consumption in men diagnosed with prostate cancer (2002 to 2005) for two years before the date of diagnosis.
The researchers included 630 patients with a median follow-up of 6.4 years, during which time there were 140 recorded prostate cancer recurrence/progression events. About 61 percent of patients reported intake of one or more cups of coffee per day. The risk of prostate cancer recurrence/progression was significantly lower with coffee consumption (adjusted hazard ratio for at least four cups/day versus no more than one cup/week, 0.41). About 14 percent of patients consumed at least one cup of tea per day, but there was no correlation seen between tea consumption and prostate cancer recurrence/progression.
"Results indicate that higher pre-diagnostic coffee consumption is associated with a lower risk of prostate cancer recurrence/progression," the authors write. "This finding will require replication in larger studies."
