The benefit of primary or adjuvant irradiation in the treatment of mixed Müllerian tumors is still not clear.


During 1981-1997 63 patients were referred for primary (n = 13) or postoperative (n = 50) radiotherapy. Analysis of outcome of primarily and postoperatively irradiated patients was performed separately because of different staging systems. Of 50 patients treated after surgery 29 presented in histopathologic stage I, 4 in stage II, 14 in stage III, and 3 in stage IV. Clinical stage distribution for primary treatment was stage I: n = 9, stage II: n = 1, stage III: n = 3. Forty-four patients in the postoperatively treated group and 6 in the primarily treated group received radiotherapy with a curative intent; external beam therapy was given up to 56 Gy to the pelvis combined with intravaginal or intracavitary brachytherapy.


Five-year actuarial overall survival, disease-specific survival, local control, and distant control for 50 patients receiving adjuvant irradiation was 52.9, 57. 5, 83.4, and 70.8%, in stage I: 68.4, 76.1, 95.2, and 81.7%, in stage II: 50.0, 50.0, 75.0, and 66.7%, and in stage III: 31.3, 34.1%, 70.4, and 47.6%, respectively. Four of 13 patients treated with primary irradiation achieved long-term local control.


These data suggest that adjuvant radiotherapy improves local control and disease specific survival in the treatment of mixed Müllerian tumors compared to data in the literature concerning treatment by surgery alone.
