Plaque radiotherapy is a common treatment for uveal melanoma. However, local failure has been reported in up to 20% of patients. We use intraoperative ultrasonography at plaque insertion and removal to evaluate plaque movement as a potential factor in local failure.

Primary Outcome Measures:
  • Plaque tilt using intraoperative ultrasonography [ Time Frame: End of study ]
  • Local melanoma failure [ Time Frame: End of study ]

Estimated Enrollment: 175
Study Start Date: July 2000
Estimated Study Completion Date: July 2007
Estimated Primary Completion Date: July 2007 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: Intraoperative ultrasonography
    Intraoperative ultrasonography will be used to determine plaque placement.
Detailed Description:
Episcleral plaque radiotherapy is a common treatment for uveal melanoma and results in local tumor control in most cases. However, local failure has been reported in a substantial proportion of patients. Since local failure greatly increases the risk of metastatic death, identifying and correcting the causes of local treatment failure are of paramount importance. Poor plaque localization is an important contributing factor to local failure. With the aid of intraoperative ultrasonography, most malpositioned plaques can be identified and readjusted at the time of plaque insertion. However, little is known about plaque movement during the 4-5 days of brachytherapy, which could also contribute to local failure. To address this question, we perform intraoperative B-scan ultrasonography at the time of iodine-125 radioactive plaque insertion and removal in uveal melanoma patients.
