Novel Prostate Cancer Hypothesis – CT Measurement of Periprostatic Fat Proves Superior Indicator of its Belligerence

A remarkable premise put forth by Dr. Joep van Roermund and associates indicate that computed tomography (CT) measurement of periprostatic fat could be a finer forecaster of prostate cancer (CaP) aggressive behaviour as compared to body mass index or BMI.

This theory was suggested on the basis of the fact that intra-abdominal adipose tissue has the maximum metabolically active fatty tissue. The report findings nevertheless revealed that periprostatic adipose tissue did not show correlation with prostate cancer (CaP) aggressiveness in this patient group.

The authors of the study indicates that waistline girth as a marker of visceral fat might be a better forecaster to gauge CaP possibility as compared to solely body mass index, particularly amongst males having a low body mass index.

The authors revealed that computed tomography was additionally an accurate means of intra-abdominal fat measurement.

The study involved 902 male entrants having prostate cancer (CaP) and undergone brachytherapy during 2004-2008. Computed tomography scans were acquired a day subsequent to seed placement. There were 725 males having satisfactory quality CT scans at hand. Calculation of BMI was done and stratification of men into three groups was done, namely: normal (lesser than 25), overweight (between 25 and 30) and obese (over 30). Computation of periprostatic adipose tissue area and % fat density was conducted. Stratification of patients on the basis of fat density was done into 3 sets namely: below 25 score, between 25 and 75 score and above 75 score.

The average age of patients in the study was sixty-six years and the average body mass index computed was 25.8 kilogram/meter sq. and fat density came to 31.8 percent. Normal BMI was noted in 37.2 percent of the patients, 50.2% were in the overweight group and 12.6% in the obese group. There was a considerable link in between body mass index and fat-density sets, periprostatic fat and thickness of fat lying just underneath the skin. Noteworthy were the outcomes of males with normally occurring BMI, thirty-one percent of them had a below 75 score of fat density. Nevertheless, there was dearth of statistically major association in-between diverse fat measurement and elevated risk ailment.
