Registry and Database Lap Prostatectomy

Prostate Cancer Clinical Trial

Official title: Laparoscopic Radical Prostatectomy: A Registry and Database

Status Completed

Clinical Trial Summary

Recently, many centers have begun offering laparoscopic radical prostatectomy (LRP) as a minimally invasive therapy for localized prostate cancer.1-6 LRP may offer the advantages of improved neurovascular bundle sparing, a more precise urethrovesical anastomosis, shorter hospitalization, and decreased convalescence.

Our group at Methodist Urology, LLC has extensive experience in laparoscopy and in treating prostate cancer and are planning to offer LRP. We intend to maintain a registry and database to document the outcomes with LRP.

Clinical Trial Description

Prostate cancer is the second leading cause of cancer death in men today. An estimated 220,900 new cases will be diagnosed in 2003 according to the American Cancer Society.7 Prostate cancer will account for one-third of the new cancer diagnoses in men in 2003. Prostate specific antigen (PSA), a sensitive screening method for prostate cancer, has helped diagnose prostate cancer at earlier stages. Stamey et al. found that the diagnosis of prostate cancer in patients with T1c disease (no abnormalities on digital rectal examination but elevated PSA) increased from10% in 1988 to 73% in 1996 and the increase in organ confined cancers increased from 40% to 75% over the same time period.8

Current surgical options for organ confined prostate cancer include open radical retropubic prostatectomy, open radical perineal prostatectomy, radioactive seed implantation, and radiation therapy. Open radical retropubic prostatectomy was pioneered in 1947 by Millin but what was slow to gain widespread acceptance secondary to associated morbidity.9-13 Refinement of the retropubic approach by Walsh has greatly improved outcomes, making it the most common surgical approach for radical prostatectomy.14, 15

As with other procedures, interest in the laparoscopic approach for radical prostatectomy developed in hopes of minimizing patient morbidity. In 1992, Schuessler et al performed the first LRP but the technical difficulties of the procedure at that time prohibited the widespread application of this technique.16 In 1998, Guillonneau et al introduced the Mountsouris technique in which a transperitoneal approach was used to perform the LRP.17, 18 Other groups have used this approach and even adapted this technique to perform extraperitoneal approaches to LRP.1, 2, 4, 5, 19, 20 Many centers are currently offering LRP as primary therapy for organ confined prostate cancer.

All curative surgical therapies for prostate cancer, whether performed in an open or laparoscopic manner, can result in impotence and/or incontinence. Incontinence can be treated with simple measures, such as muscle strengthening exercises, or if more bothersome, can be treated with surgical therapy. Impotence can be treated with medications or, if needed, surgery.

The relative risk of having positive surgical margins in patients undergoing open radical retropubic prostatectomy compared to laparoscopic radical prostatectomy is not known. Preliminary publications regarding laparoscopic radical prostatectomy report rates of positive surgical margins (13-25%) that are similar to open radical prostatectomy (11-46%).2, 5, 6, 19, 21-28 However, long-term follow-up is not available for patients undergoing laparoscopic radical prostatectomy, so the impact of positive margins on long-term survival is not known. ;
