Long-term follow-up and complications of infants with vulvovaginal embryonal rhabdomyosarcoma treated with surgery, radiation therapy, and chemotherapy.

The long-term follow-up is presented of three infants with vulvovaginal rhabdomyosarcoma treated at 10, 11, and 15 months of age by radical surgery, pelvic radiation therapy, and chemotherapy. Two patients developed colonic stricture requiring operative repair. One of these two patients also has urinary incontinence secondary to severe bladder contraction. Pelvic radiation did not significantly affect stature. Lateral transposition of the ovaries at the time of surgery preserved endocrine function in one patient with a normal puberty. The other two patients developed normal secondary sexual characteristics with hormonal replacement therapy. These patients perform well academically and socially. They have adapted 14, 14, and 16.5 years after their therapy.
