The age of the patients ranged from 19 to 40 years, with a median age of 23 years. Four patients were diagnosed as stage Ia, two as Ib and one as Ⅱ a, 6 cases were treated with surgery, chemotherapy and/or radiotherapy, and 1 with surgery only, 5 cases in this group survived more than 5 years with a mean 7.9 years of follow-up. The prognosis for cervical sarcoma botryoides is similar to that of other female genital tract embryonal rhabdomyosarcomas. Primary therapy should consist of vincristine and dactinomycin based chemotherapy. Surgery should be guided by the response to initial chemotherapy and should attempt to conserve the function of the bladder, rectum, vagina, and ovaries. Radiotherapy was used for involved surgical margins or positive nodes. The effect of radiotherapy is unclear for stage Ia cases.展开更多
