The reports on relationship of obesity and biochemical or clinical recurrence of prostate cancer are controversial. Several reports have shown that obesity is associated with increased risk of biochemical or clinical failure after radical prostatectomy. Other prospective studies have shown no adverse effect of obesity on long-term outcomes after prostatectomy. Limited reports are available on the impact of obesity on prostate cancer progression after radiotherapy.
