This prospective cohort study investigate impact of diet and environment factors on the promoting and developing prostate cancer and include two cohorts as indicated below.
The cohort 1 investigates impacts of serum isoflavone concentration and life-style (diet including soybean, isoflavone and lycopene, etc.) on the initiation and promotion of prostate cancer. Participants are men aged between 35 and 44 who participate in prostate-specific antigen (PSA)-based screening in Kurosawa Hospital. Participants will be checked baseline serum isoflavone and life-style in 20-25 years old and at the enrollment using a validated questionnaire and will be followed for 5 to 8 years. The surrogate primary endpoints are risk of increased PSA above 2.0ng/ml or 3.0ng/ml and changes in the ratio of free to total PSA (%f-PSA) below 15% or 10%. The impact of baseline isoflavone concentration and life-style in 20-25 years old and at the enrollment on the surrogate endpoints will be investigated.
The cohort 2 investigates impacts of serum isoflavone concentration and life-style on the development of clinically manifested prostate cancer. Participants are men aged between 45 and 54 including high risk men whose baseline PSA above 2.0ng/ml and low risk men with PSA below 2.0ng/ml. The baseline assessment is the same as the cohort 1. The impact of baseline isoflavone concentration and life-style in 20-25 years old and at the enrollment on the development clinically manifested prostate cancer will be investigated.
