Objective. To access the predictors and structure of the postoperative Clavien-Dindo grade ≥3 complications in the bladder cancer patients after the radical cystectomy (RC) and to create the model to predict the likelihood of such complications.
Methods. Results of the radical cystectomy series performed in N.N. Alexandrov National Cancer Center of Belarus during the period from 1999 to 2012 (849 patients) were retrospectively analyzed. The information about postoperative Clavien-Dindo grade ≥3 complications during 30 days after the radical cystectomy was obtained from medical records. By means of uni- and multivariate logistic regression analyses, the relationship of severe postoperative complications with perioperative parameters was assessed.
Results. Postoperative complications were registered in 351 patients from 849 (41%). 116 patients had 128 Clavien-Dindo grade ≥3 complications (13.7%, 95% CI 11.4-16.0). Multivariate regression analysis revealed the statistically significant correlation of complications frequency of Clavien-Dindo grade ≥3 with the following factors: surgeons experience (<50 versus >200 RC: OR 3.252; 95% CI 1.297-8.157; p=0.011; 50-200 versus >200 RC: OR 2.61; 95% CI 1,456-4,89; p=0.002), patients age (<70 versus ≥70: OR 1.779; 95% CI 0.125-2.815; p=0.014), body mass index (BMI) (<25 versus ≥25: OR 1.779; 95% CI 1.117-2.821; =0.04), previous open bladder surgery (OR 3.479; 95% CI 1.055-11.409; =0.015), preoperative serum creatinine level (<155 mmol/l versus ≥155 mmol/l, OR 2.762, 95% CI 1.415-5.388; p=0.003).
Conclusions. Complication rate is influenced by patients parameters (BMI ≥25, age ≥70 and serum creatinine level ≥155 mmol/l) and surgeon experience, which should be taken into account before planning radical cystectomies.
