Safety and Efficacy of Palliative Radiotherapy (25 Gy × 5 Fractions) for Symptomatic Pelvic Tumors

The treatment plan of a representative patient is shown. The patient had a recurrence of ovarian cancer at the vaginal stump which caused bleeding. The light blue line shows the tumor in the figure on the left. Beams were created from 5 directions to ensure coverage of the tumor while avoiding high doses to the rectum. The dose distribution is shown in color wash, and the red thin line indicates 95% of the prescribed dose (25 Gy in 5 fractions). Diagnostic computed tomography image with contrast media of the same patient taken 6 months after treatment is shown on the right figure. The tumor shrunk well, and bleeding was controlled.
