In unadjusted analyses rural-dwelling men were older compared to urban-dwelling men (72 years versus 68.5 years, p = 0.035), had higher median PSA values (22.9 ng/ml versus 18 ng/ml, p = 0.001), higher local tumour stage (65.2 % versus 34.8 % T3 disease; 73.7 % versus 26.3 % T4 disease; p = 0.005), higher mean Gleason scores (p = 0.048) and more non-curative initial treatments. The gene discussed is KLK3; the disease is neoplasm.
