Methods.:A review was conducted on patients (pts) treated with palliative RT for symptomatic ovarian cancer at The Ottawa Hospital Regional Cancer Centre between 1990 and 2003. Patient demographics,tumor factors,treatment variables,and clinical outcome were entered into a database. Symptom response was defined as complete (CR),partial (PR),or none. Results.:62 courses of RT were delivered to 53 pts. The symptoms treated were:bleeding (40%),pain (37%),and ‘others’(23%). The most common dose fractionation scheme was 30 Gy in 10 fractions (f) (range:5 Gy/1 f to 52.5 Gy/20 f). The overall response rate was 100%,with 68%achieving a CR. The CR rates were 88,65,and 36%for the symp- toms of bleeding,pain,and ‘others’,respectively (P = 0.003). The median duration of response was 4.8 months (range:1-71 months). In multivariate analysis,the only factors that were found to be significant positive predictors of symptom control were:the symptom bleeding (P = 0.015) and stage III/IV disease at presentation (P = 0.01). The most commonly reported toxicities were grades 1 and 2 nausea/vomiting and diarrhea. There were no grade 3/4 toxicities reported. Conclusions.:Radiotherapy is highly effective in palliating symptomatic ovarian cancer. Excellent results are achieved for patients presenting with bleeding or pain. Symptomatic patients should be strongly considered for palliative radiotherapy. Higher doses of radiotherapy should be considered for those with symptoms other than bleeding or pain and those with longer life expectancies.展开更多

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 ×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 ×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 30Gy in 20 fractions. The dominant mass shrank from 13 ×17 cm to 5.1 ×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 ×20 ×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 ×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.展开更多
