What is the second most common cancer in men?
Prostate cancer (PCa) is the second most common cancer and fifth leading cause of death in men. There were 1.1 million patients diagnosed with PCa worldwide in 2012 accounting for 15% of the total diagnosed cancers in men and 307,000 deaths, representing 6.6% of the total male cancer mortality.1Diet, lifestyle, environment, and genetics are regarded as risk factors for PCa. A case-control study in Western Australia found that a Western dietary pattern with high intake of red or processed meats, fried fish, chips, high-fat milk and white bread was associated with a higher risk for PCa.2In recent decades, growth of the Chinese economy accompanied with a shift towards western lifestyle has been associated with an increased prevalence of PCa in China. The overall incidence of PCa in China increased from 3.80/100,000 in 2001 to 7.10/100,000 in 2011 and in urban areas from 4.49/100,000 to 10.06/100,000).3,4The World Cancer Research Fund has reported that a high intake of fruit and vegetable may be beneficial in reducing the risk of cancer including PCa.5Tomatoes and tomato products, which contain abundant lycopene, are in particular recommended for PCa prevention. Lycopene, a 40-carbon carotenoid molecule, has been identified as an antioxidant agent with potential anti-cancer properties and no obvious side effects.6
How to derive a linear dose response curve?
To derive a linear dose–response curve, the distribution of cases and person-years, or cases and non–cases with RRs and estimates of uncertainty (such as CIs) for at least 3 categories of quantified lycopene intake or circulating concentrations was required to be presented in the included studies. If the total number of cases or person-years was presented without distribution, we estimated the distribution on the basis of definitions of the quantiles. If the unit for circulating concentrations was μmol/L, it was multiplied by 536.85 (relative molecular weight of lycopene) and adjusted to μg/L.
Is lycopene an anticancer?
Prostate cancer (PCa) is a common illness for aging males. Lycopene has been identified as an antioxidant agent with potential anticancer properties. Studies investigating the relation between lycopene and PCa risk have produced inconsistent results. This study aims to determine dietary lycopene consumption/circulating concentration and any potential dose–response associations with the risk of PCa. Eligible studies published in English up to April 10, 2014, were searched and identified from Pubmed, Sciencedirect Online, Wiley online library databases and hand searching. The STATA (version 12.0) was applied to process the dose–response meta-analysis. Random effects models were used to calculate pooled relative risks (RRs) and 95% confidence intervals (CIs) and to incorporate variation between studies. The linear and nonlinear dose–response relations were evaluated with data from categories of lycopene consumption/circulating concentrations. Twenty-six studies were included with 17,517 cases of PCa reported from 563,299 participants. Although inverse association between lycopene consumption and PCa risk was not found in all studies, there was a trend that with higher lycopene intake, there was reduced incidence of PCa (P = 0.078). Removal of one Chinese study in sensitivity analysis, or recalculation using data from only high-quality studies for subgroup analysis, indicated that higher lycopene consumption significantly lowered PCa risk. Furthermore, our dose–response meta-analysis demonstrated that higher lycopene consumption was linearly associated with a reduced risk of PCa with a threshold between 9 and 21 mg/day. Consistently, higher circulating lycopene levels significantly reduced the risk of PCa. Interestingly, the concentration of circulating lycopene between 2.17 and 85 μg/dL was linearly inversed with PCa risk whereas there was no linear association >85 μg/dL. In addition, greater efficacy for the circulating lycopene concentration on preventing PCa was found for studies with high quality, follow-up >10 years and where results were adjusted by the age or the body mass index. In conclusion, our novel data demonstrates that higher lycopene consumption/circulating concentration is associated with a lower risk of PCa. However, further studies are required to determine the mechanism by which lycopene reduces the risk of PCa and if there are other factors in tomato products that might potentially decrease PCa risk and progression.
Does lycopene affect PCA?
In a meta-analysis32published in 2003, Etminan et al found an inverse association. However a study published in 2013 by Chen et al found no effect.33Moreover, these 2 meta-analyses did not evaluate the dose–response association with risk reduction or determine a beneficial range of consumption and both suggested a further study was needed to determine the type and quantity of tomato products for preventing PCa. In 2014, a high-quality 24-years follow-up nested case-control (NCC) study20including 51,529 US healthy men suggested a reduced odds of PCa for those with highest lycopene intake when compared to those with lowest lycopene intake (hazard ratio [HR] 0.91, 95% confidential interval [CI] 0.84 to 1.00). As inconsistencies between studies may relate to different exposure levels, it is important to determine the shape of the dose–response curve. It is also possible that only those individuals with a low baseline lycopene intake or status may benefit from higher lycopene consumption. However, none of previous reviews have investigated these issues. Therefore we conducted an updated systematic review to clarify whether lycopene intake or serum concentration is inversely related to PCa, with particular emphasis on the shape of the dose–response curve.

A 2013 review of all such lycopene supplement trials “failed to support [the initial] optimism.” In fact, they were just happy that the lycopene pills didn’t end up causing more cancer, like beta-carotene pills did. But, then came 2014. Researchers in Italy had been giving the largest doses they could of lycopene, selenium, and isolated green tea compounds to men with precancerous prostate lesions, hoping they could prevent full-blown cancer. But, in 2014, the expanded results of a similar trial were published, in which selenium and vitamin E supplements resulted in more cancer. Yikes! So, these researchers stopped their trial, and broke the code to unblind the results, And indeed, those taking high doses of lycopene, green tea catechins, and selenium appeared to get more cancer than those who just got sugar pills.
