The role of radiation therapy for uterine cervical cancer with distant metastasis.

OBJECTIVE

We carried out a review to determine the role of radiation therapy in uterine cervical cancer with distant metastasis.

METHODS

Forty-four patients with uterine cervical cancer with distant metastasis underwent radiation therapy; 29 of these also underwent chemotherapy. A total dose of 19.8-90.4 Gy (median 62.9 Gy) was delivered to the cervical tumors.

RESULTS

Thirty-three patients died during the follow-up period of 1-94 months (median 10 months) after irradiation. The overall survival rate at 3 years was 20%, and the estimated median survival time was 15 months. Ten patients developed primary tumor progression, and the primary tumor control rate at 3 years was 49%. A distant metastatic site and primary tumor size were significant prognostic factors for their survival. Total radiation dose was considered a significant and useful variable for primary tumor control. With the exception of transient hematologic reactions and hemorrhagic cystitis, there were no therapy-related toxicities of grade 3 or greater.

CONCLUSIONS

Radiation therapy was safe and effective for local control in patients with uterine cervical cancer with distant metastasis. More aggressive treatment, including radiation therapy with a curative radiation dose, should be considered for patients with favorable prognostic factors for survival.
