The combination of lycopene and vitamin E has been shown to be far more
effective in inhibiting the growth of prostate cancer than the effect
of lycopene alone, according to new research from BASF. A phase-2
clinical trial on humans is under way, but initial results with mice,
published in the May issue of the Journal of Nutrition are encouraging
Tumour suppression was increased 73% (compared to 53% for lycopene
alone) and survival time increased by 40% (19% for lycopene alone) in a
study carried out by the urology department of the Erasmus University in
Rotterdam, the Netherlands. BASF investigated how different doses of
lycopene and vitamin E affect prostate tumour growth, and whether a
combination of the two exerts additional effects. The PSA
(prostate-specific antigen) levels in blood ? a marker for tumour growth
? were also monitored. Combined treatments using comparatively low
dosage ? just 5mg/kg body weight for each product ? was shown to be most
effective. PSA levels were proportional to tumour size, regardless of
the dietary supplementation received, indicating that supplements of
lycopene and vitamin E are unlikely to interfere with PSA measurements
for diagnostic purposes.
