Introduction: Prostate cancer is an important public health concern in Brazil, especially among older men, with a significant mortality rate. In addition to advanced age, obesity emerges as a relevant risk factor, associated with a worse prognosis of the disease.
Objective: To investigate the relationship between body mass index (BMI) and Gleason score in older and very older patients with prostate cancer indicated for radiotherapy treatment.
Methods: Prospective, descriptive, and longitudinal study with 258 patients with prostate cancer, evaluating age, initial PSA, BMI, race, and Gleason Score.
Result: Findings revealed an association between a higher BMI and a more aggressive degree of disease, as indicated by higher Gleason scores.
Conclusion: Overweight and obese patients have a higher and more evident Gleason score in older patients compared to the very older, being more notable in the older. This study is one of the few studies to examine the link between BMI and poor prognosis in prostate cancer patients
