  • Preoperative staging using magnetic resonance imaging and risk of positive surgical margins after prostate-cancer surgery
  • 2019
  • Ingår i: Prostate Cancer and Prostatic Diseases. - : Nature Publishing Group. - 1365-7852 .- 1476-5608. ; 22:3, s. 391-398

    • Background: It is unclear whether preoperative staging using Magnetic Resonance Imaging (MRI) reduces the risk of positive margins in prostate cancer. We aimed to assess the effect on surgical margins and degree of nerve sparing of a pelvic MRI presented at a preoperative MRI conference. Methods: Single institution, observational cohort study including 1037 men that underwent robot assisted radical prostatectomy between October 2013 and June 2015. Of these, 557 underwent a preoperative MRI combined with a preoperative MRI conference and 410 did not. With whole-mount prostate specimen histopathology as gold standard we assessed the ability of MRI in finding the index tumor and the sensitivity and specificity for extra prostatic extension. We calculated relative risks for positive surgical margins and non-nerve sparing procedure, adjusting for preoperative risk factors using stabilized inverse-probability weighting. Results: MRI detected the index tumor in 80% of the cases. Non-organ confined disease (pT3) at histology was present in the MRI and the non-MRI group in 42% and 24%, respectively. Rate of positive surgical margins comparing the MRI and non-MRI groups was 26.7% and 33.7%, respectively, relative risk 0.79 [95% CI 0.65-0.96], weighted relative risk (wRR) 0.69 [95% CI 0.55-0.86]. The wRR of extensive positive surgical margins was 0.45 [95% CI 0.31-0.67]. Undergoing MRI was also associated with an increased risk of being operated with a non-nerve sparing technique (wRR, 1.84 [95% CI 1.11-3.03]). Conclusions: Our study suggests that preoperative prostate MRI in combination with a preoperative MRI conference affects the degree of nerve-sparing surgery and reduces positive surgical margins.

  • Objectively measured mobilisation is enhanced by a new behaviour support tool in patients undergoing abdominal cancer surgery
  • 2019
  • Ingår i: European Journal of Surgical Oncology. - 0748-7983 .- 1532-2157. ; 45:10, s. 1847-1853
  • Tidskriftsartikel (refereegranskat)abstract
    • INTRODUCTION: Mobilisation reduces the risk of complications after abdominal surgery. Despite that, patients spend most of their time immobilised during hospital stay. Hence, the aim of this study was to evaluate a tool called the Activity board, which includes behaviour change techniques, regarding effects on mobilisation and postoperative recovery after abdominal cancer surgery.MATERIAL AND METHODS: Patients who were planned for abdominal surgery due to colorectal, ovarian or urinary bladder cancer, and at least three postoperative days at Karolinska University Hospital were included in this non-randomised controlled trial, from January 2017 to May 2018. The patients were allocated to Activity board or standard treatment when they were admitted to hospital. Mobilisation was evaluated objectively with activity monitor the first three postoperative days, and postoperative recovery was assessed continuously during hospital stay.RESULTS: In total, 133 patients, mean (sd) age 68.1 (12.3) years were included. The patients with the Activity board had postoperatively higher levels of mobilisation, compared to standard treatment, as mean value over the first three days, steps, median (min-max) 1057 (3-10433) and 360 (0-6546), respectively (p = 0.001), and for each day separately. Further, the group with the Activity board had a shorter length of stay, 6 (3-13), compared to standard treatment 7 (3-14) (p = 0.027).CONCLUSION: The Activity board is an effective tool to enhance mobilisation after abdominal surgery due to cancer, in hospital settings. Using the Activity board could lead to improved postoperative recovery.
