Upper tract transitional cell carcinoma is an uncommon cancer mainly affecting the draining system of the kidney (kidney pelvis) and ureter (the tube through which urine passes from the kidney to the bladder). The main treatment approach for this condition is surgical removal of the malignant area. There are a number of surgical techniques for this procedure and the aim of this review was to compare them and determine which was the most effective in terms of surgical ease, patient morbidity, clinical outcome and cost. Our search of the literature found no high quality evidence comparing different surgical techniques. Evidence from one small randomised trial and observational studies suggests that laparoscopic surgical intervention may reduce blood loss, post-operative pain and hospital stay. However, the quality of the evidence is poor and, therefore, it is not possible to recommend the most effective surgical procedure to replace the existing clinical practice for managing upper tract transitional cell carcinoma.

Upper tract transitional cell carcinomas (TCC) are uncommon and aggressive tumours. There are a number of surgical approaches to manage this condition including open radical nephroureterectomy and laparoscopic procedures.
วัตถุประสงค์
To determine the best surgical management option for upper tract transitional cell carcinoma.
วิธีการสืบค้น
A sensitive search strategy was developed to identify relevant studies for inclusion in this review. The following databases were searched for randomised trials evaluating surgical approaches to the management of upper tract TCC: Medline EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, British Nursing Index, AMED, LILACS, Web of Science®, Scopus, Biosis, TRIP, Biomed Central, Dissertation Abstracts, and ISI Proceedings.
เกณฑ์การคัดเลือก
The following criteria that were considered for this review.
Types of studies - All randomised or quasi-randomised controlled trials comparing the various surgical methods and approaches for the management of localised upper tract transitional cell carcinoma.
Types of participants - All adult patients with localised transitional cell carcinoma. Localised disease was defined as limited to the kidney or ureter with no gross regional lymph nodal enlargement on imaging.
Types of interventions - Any surgical method or approach for managing localised upper tract transitional cell carcinoma.
Types of outcome measures - Overall and cancer-specific survival were primary outcomes. Surgery-related morbidity. Quality of life and health economics outcomes were secondary outcomes.
การรวบรวมและวิเคราะห์ข้อมูล
Two review authors examined the search results independently to identify trials for inclusion.
ผลการวิจัย
We identified one randomised controlled trial that met our inclusion criteria. The trial showed that the laparoscopic approach had superior peri-operative outcomes compared to open approach. Laparoscopic was superior and statistically significant for blood loss (104 mL (millilitres) versus 430 mL, P < 0.001) and mean time to discharge (2.3 days versus 3.7, P < 0.001). Oncological outcomes (bladder tumour-free survival, metastasis-free survival, cancer-specific survival curves), at a median follow up of 44 months and in organ-confined disease, were comparable for both groups.
ข้อสรุปของผู้วิจัย
There is no high quality evidence available from adequately controlled trials to determine the best surgical management of upper tract transitional cell carcinoma. However, one small randomised trial and observational data suggests that laparoscopic approach is associated with less blood loss and early recovery from surgery with similar cancer outcomes when compared to open approach.
