Evaluation of perioperative complications in the elderly with radical prostatectomy / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the incidence and severity of perioperative complications in elderly patients with radical prostatectomy (RP).</p><p><b>METHODS</b>A total of 242 patents underwent RP for prostate cancer were retrospectively assessed, whose clinicopathologic factors and perioperative complications were retrieved from the medical records. The mean age in the elderly group (n = 163) and control group (n = 79) were (73.2 ± 2.4) and (63.2 ± 4.8) years, respectively. The clinicopathologic factors including Charlson comorbidity index and preoperative prostate specific antigen were statistically significant different. The difference of clinicopathologic factors and perioperative complications between the elderly group (≥ 70 years old) and control group were statistically analyzed using the SPSS 17.0.</p><p><b>RESULTS</b>The incidence of perioperative complications was 23.5% in the elderly group and 22.7% in the control group. Except for gross hematuria (there were 12 cases in elderly group and 1 case in control group, respectively, χ(2) = 3.89, P < 0.05) and perioperative transfusion (there were 36 cases in elderly group and 7 cases in control group, respectively, χ(2) = 6.37, P < 0.05), there was no significant difference in each kind or total of perioperative complications.</p><p><b>CONCLUSION</b>The elderly patients underwent RP in experienced center are not associated with higher or more serious perioperative complications.</p>

The building and validation of a model to predict the bone metastases of patients with newly diagnosed prostate cancer / 中华外科杂志

<p><b>OBJECTIVE</b>To develop and validate a nomogram used to predict the bone metastasis risks according to the clinicopathological factors of patients with newly diagnosed prostate cancer.</p><p><b>METHODS</b>The 501 cases were randomly assigned into development sample (300 cases) and validation sample (201 cases). In the development sample, Logistic regression analysis was used to explore the predictors of bone metastases, and then a nomogram was built based on regression coefficients and validated in the validation sample.</p><p><b>RESULTS</b>Prostate specific antigen, cT3, cT4 and Gleason score ≥ 8 were the independent prognostic factors (P < 0.05), and the OR values were 5.65, 2.89, 9.07 and 2.87 respectively. The concordance index was 0.830 in the model sample and 0.799 in the validation sample.</p><p><b>CONCLUSION</b>A nomogram, built based on the clinicopathological factors, could be used to predict the risk of bone metastases and then could be helpful for the rational use of bone scan.</p>
