Transitional Cell Carcinoma

A prospective single-arm two-stage phase II study to allow for analysis of the treatment-specific outcomes and disease-specific survival of patients treated with open or laparoscopic nephroureterectomy and bladder cuff excision along with a lymph node dissection (modified template retroperitoneal lymph node dissection).

The lymph nodes will be sent to pathology for review.

Lymph Node Dissection

Philippe Spiess, M.D.

The primary objective is to show that performing a lymph node dissection may detect occult nodal metastasis in this patient population whereby providing important diagnostic information, with potential therapeutic benefits in patients with isolated nodal metastases.

In case of urothelial carcinoma of the upper urinary tract (a cancer originating from the inner lining of the urinary tract) requiring the removal of the kidney, ureter, and cuff of bladder (a surgical termed a nephroureterectomy). Previous studies in urothelial carcinoma of the bladder, have shown that doing a lymph node dissection (surgically removing the lymph nodes) may improve survival, or at least give an idea of what patients may need chemotherapy (drugs to control the cancer cells that are outside the kidney-ureter) earlier (before the nodes are enlarged in the imaging studies).

Participants will have a nephroureterectomy (taking the kidney and the ureter). Investigators will also be doing a lymph node dissection (taking the patient's lymph nodes in the same side of the kidney) to look for malignancy outside of the kidney and ureter. The lymph nodes will be sent to pathology for review.

Study visits will be scheduled 10 to 14 days after surgery for removal of stitches and analysis of the patient's pathology report.

The following procedures will be done:

* History and physical examination, urinary cytology (test to look for malignant cells in the urine) and surveillance cystoscopy (procedure to look inside the urethra and bladder which is performed in the office under local anesthesia) every 3 months for the first 2 years after treatment, every 6 months for the next 2 years and yearly thereafter if the patient is free from recurrence.
* Radiographic studies including chest x-ray and abdomino-pelvic computed tomography (CAT scans) will be performed every 6 months for the first 2 years and then yearly thereafter.
* Bone scan (special imaging study to look for cancer spread in bone) in case of bone pain or elevated alkaline phosphatase level.

After surgery patients will be followed every 3 months for the first 2 years after treatment, every 6 months for the next 2 years and yearly thereafter if they are free from recurrence.

Merits of Performing a Modified Template Retroperitoneal Lymph Node Dissection

Merits of Performing a Modified Template Retroperitoneal Lymph Node Dissection at Time of Nephroureterectomy for Urothelial Carcinoma of the Upper Urinary Tract

The number of participants having pathologically proven lymph node metastasis at the time of radical nephroureterectomy (RNU) and modified retroperitoneal lymph node dissection (RPLND).

The primary endpoint is the detection via lymph node dissection of pathological node positive urothelial carcinoma in patients treated with open or laparoscopic nephroureterectomy for upper tract urothelial cancer.

The mean (range) total lymph node count and lymph node count per procedure category. Between 2009 and 2011, patients with suspected upper urinary tract urothelial carcinoma (UUT-UC) underwent open, laparoscopic, or robot-assisted radical nephroureterectomy (RNU) with modified retroperitoneal lymph node dissection (RPLND).

The sample size was small because it was a single institution study. It was thus underpowered to achieve a cancer-specific endpoint pertaining to the oncological merit of performing a modified RPLND in the context of UUT-UC.

All evaluable participants. On histopathological review, one patient had a benign angioma and was excluded from the final data analysis.
