Estimated 5-year survival was 10% (median: 4.5 months). Tumor size less than 6.0 cm (p = .004) and female gender (p = .02) were significant prognostic factors. Five patients who underwent complete resection had an estimated 5-year survival of 60% (median: 131 months). Four of these patients had postoperative radiotherapy with or without sequential chemotherapy. Two of these patients survived more than 10 years, and a third remains alive without disease at 26 months.
