Two cases of post-radiation osteosarcoma of the sacrum after pelvic irradiation for uterine cervical cancer
Background: Post-radiation pelvic bone sarcoma can result as a long-term sequela of pelvic irradiation for uterine cervical cancer. Case: A 59-year-old woman who had received pelvic irradiation for Stage IIB uterine cervical cancer 16 years before was diagnosed as having post-radiation osteosarcoma of the sacrum. Another 66-year-old woman who had received pelvic irradiation for Stage IIIB uterine cervical cancer seven years previously was also diagnosed as having pleomorphic sarcoma of the sacrum. Conclusion: When a bone lesion is observed at a previously irradiated field, post-radiation sarcoma should be considered and differentiated from bone metastases.
