| Scientific title | A multimodality technique of single photon emission computed tomography fused with computed tomography (SPECT-CT) and intraoperative verification by gamma probe used to map the primary lymphatic landing sites of the urinary bladder wall in patients scheduled for cystectomy |
| Study hypothesis | Surgical excision and histological examination of the pelvic lymph nodes (LNs) provides the most accurate staging regarding pelvic lymph node status in patients undergoing radical cystectomy for invasive urinary bladder cancer. Whilst the optimal field of lymphadenectomy is still debated, there is growing evidence that extended pelvic lymph node dissection (PLND) in patients with bladder cancer may confer a survival benefit for both node-positive and node-negative patients. The purpose of this study was to prospectively determine the anatomical location of the draining LNs after injection with a radioactive tracer in the lateral, non tumour bearing bladder wall and to evaluate the implications for the extent of PLND in strictly unilateral bladder cancer. |
| Ethics approval(s) | Ethics Committee of Bern, approved in February 2007 (ref: 31/07) |
| Condition | Lymphatic drainage of urinary bladder in bladder cancer patients |
| Intervention | Preoperative flexible cystoscopy guided injection of technetium into the bladder wall in patients with bladder cancer scheduled for cystectomy and extended PLND. Thereafter, all patients undergo preoperative SPECT-CT to detect Tc 99m positive nodes. Intraoperative gamma probe detection at the time of PLND. Removal of Tc 99m positive nodes separately. Backup extended PLND to detect possibly missed Tc 99m positive nodes. |
