ABSTRACT

Prostate cancer, one of the most common malignant tumors among men, is closely associated with obesity and, thus far, several studies have suggested the association between obesity and aggressive pathological characteristics in the United States. However, the effect of obesity on prostate cancer mortality is controversial, and it remains unclear whether obesity contributes to the aggressiveness of prostate cancer in Asian patients. The aim of the present study was to investigate the association between body mass index (BMI) and the clinicopathological characteristics of prostate cancer in 2,003 Japanese patients who underwent radical prostatectomy. There was a significant association between higher BMI and higher Gleason score (GS). The multivariate analysis also revealed that BMI was an independent indicator for GS ≥8 at surgery. Moreover, among patients with lower prostate-specific antigen levels, biochemical recurrence-free survival was significantly worse in those with higher BMI. These results suggest that BMI may be a classifier for predicting adverse pathological findings and biochemical recurrence after radical prostatectomy in Japanese patients.

ABSTRACT

Elderly people are at a high risk of experiencing problems with drug therapy due to age- related changes in the body, as well as exposure to many medications owing to multiple health problems. Medication-related adverse events are common amongst the elderly. Pharmacotherapy for benign prostatic hyperplasia or overactive bladder can generally im- prove lower urinary tract symptoms, whilst also improving the quality of life. However,;these drugs also have the potential to cause dangerous adverse events. For this reason, a great deal of caution should be taken when prescribing medication for elderly patients who are suffer- ing from lower urinary tract symptoms.

ABSTRACT

We herein report a case of primary lymphoma of the prostate, which arose in an 85-year-old male with dysuria. CT and MRI examinations demonstrated a large mass in the prostate. A transrectal ultrasound-guided biopsy of the prostate was performed. The histological examination showed diffuse large B-cell lymphoma. The large lesion in the prostate showed spontaneous regression. Spontaneous regression of primary lymphoma of the prostate has not been reported previously. The spontaneous regression of primary lymphoma of the prostate observed in this patient suggests that observation may represent a viable treatment option following a biopsy that has provided a histopathological diagnosis.
