  • No increased risk of short-term complications after radical cystectomy for muscle-invasive bladder cancer among patients treated with preoperative chemotherapy: a nation-wide register-based study
  • 2020
  • Ingår i: World journal of urology. - SPRINGER. - 0724-4983 .- 1433-8726. ; 38:2, s. 381-388

    • Purpose Preoperative chemotherapy is underused in conjunction with radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC) due to concerns for complications and delay of surgery. Prospective data on short-term complications from population-based settings with frequent use of preoperative chemotherapy and standardised reporting of complications is lacking. Methods We identified 1,340 patients who underwent RC between 2011 and 2015 in Sweden due to MIBC according to the Swedish Cystectomy Register. These individuals were followed through linkages to several national registers. Propensity score adjusted logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for complications and death within 90 days of surgery, comparing patients receiving preoperative chemotherapy or not. Results Minimum two cycles of preoperative chemotherapy were given to 519 (39%) of the patients, who on average tended to be younger, have higher education, better physical status, and more advanced bladder cancer than patients not receiving chemotherapy. After adjusting for these and other parameters, there was no association between treatment with preoperative chemotherapy and short-term complications (OR 1.06 95% CI 0.82-1.39) or mortality (OR 0.75 95% CI 0.36-1.55). We observed a risk reduction for gastrointestinal complications among patients who received preoperative chemotherapy compared with those who did not (OR 0.49 95% CI 0.30-0.81). Conclusion This nation-wide population-based observational study does not suggest that preoperative chemotherapy, in a setting with high utilisation of such treatment, is associated with an increased risk of short-term complications in MIBC patients treated with radical cystectomy.

  • The increased risk for thromboembolism pre-cystectomy in patients undergoing neoadjuvant chemotherapy for muscle-invasive urinary bladder cancer is mainly due to central venous access: a multicenter evaluation
  • 2020
  • Ingår i: International Urology and Nephrology. - SPRINGER. - 0301-1623 .- 1573-2584. ; 52, s. 661-669
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose To investigate if patients receiving neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC) had an increased risk of thromboembolic events (TEE) and to evaluate when these events occur on a timeline starting from 6 months pre-cystectomy, during NAC-administration and 60 months post-cystectomy. Methods Two hundred and fifty five patients undergoing radical cystectomy during 2009-2014 at three Swedish cystectomy centers (Umea, Linkoping and Sundsvall) were in-detail reviewed retrospectively, using individual medical records. One hundred and twenty nine patients were ineligible for analysis. NAC patients (n = 67) were compared to NAC-naive NAC-eligible patients (n = 59). The occurrence of TEE was divided into different periods pre-cystectomy and post-cystectomy. Statistical analyses included Chi-squared and logistical regression tests. Results Significant associations were found between receiving NAC and acquiring a TEE during NAC therapy pre-cystectomy. All but one pre-cystectomy event was venous and all but one of the patients received NAC. 31% (14/45) of TEEs occurred pre-cystectomy. The incidence of TEEs pre-cystectomy in NAC-naive NAC-eligible patients was only 10% (2/20), whereas the incidence of TEEs in NAC patients occurred pre-cystectomy in 48% (12/25) and 11/12 incidents were detected during NAC therapy-this including 7/11 (64%) incidents affecting veins in anatomical conjunction with the placement of central venous access for chemotherapy administration. Conclusions There is a significantly increased risk for TEE pre-cystectomy during chemotherapy administration in MIBC patients receiving NAC, compared to the risk in NAC-naive NAC-eligible MIBC patients. In 64% of the pre-RC TEEs in NAC patients, there was a clinical connection to placement of central venous access.
