Palliative radiotherapy for recurrent granulosa cell tumor of the ovary: a report of 3 cases with radiological evidence of response.

Abstract

BACKGROUND:

The role of radiotherapy for recurrent or residual granulosa cell tumor of the ovary (GCTO) is controversial. One reason for this controversy may be that most published studies on this topic have not utilized sectional imaging to assess response to radiotherapy. We report on three cases of recurrent or residual GCTO that were treated with radiotherapy for which pre- and post-treatment CT scans were available to assess response.

CASE REPORTS:

Case #1: A 77-year-old woman with a 7 x 10-cm pelvic mass post-surgery was treated with radiotherapy to a dose of 45 Gy in 25 fractions followed by a boost of 10 Gy in 5 fractions. Post-treatment scans revealed a decrease in tumor size to 4 x 2.5 cm. The reduction in tumor volume was 86%, and the duration of response was 13 months. Case #2: A 73-year-old woman with multiple abdominal recurrences was treated with radiotherapy to a dose of 30 Gy in 20 fractions. The dominant mass shrank from 13 x 17 cm to 5.1 x 6.6 cm. The reduction in volume was 85%, and the duration of response has been 5 months. Her symptom of abdominal bloating and early satiety abated. Case #3: An 83-year-old woman with a 20 x 20 x 15-cm mass in the left abdomen was treated with radiotherapy to a dose of 45 Gy in 25 fractions. The mass decreased in size to 3.7 x 2.5 cm post-treatment. The duration of response has been 21 months. Her symptom of left leg swelling disappeared after therapy.

CONCLUSION:

Radiotherapy is highly effective in treating recurrent or residual GCTO. In these three cases, the tumor volume decreased by 85 to 90%, and the duration of response has, up to now, been 5 to 21 months.
