Post-irradiation cytology of cervical cancer patients.
The accuracy of cervicovaginal cytology following radiotherapy for cervical cancer is compromised by the anatomical and tissue changes resulting from irradiation. Collection of representative samples may be more difficult, and benign radiation changes, post-irradiation dysplasia, and the frequent occurrence of repair cells and active stromal cells in post-irradiation smears may cause diagnostic problems. Nevertheless, cytology is a valuable tool for the detection of locally recurrent cervical cancer. It is simple and economical to perform at the time of clinical follow-up examination, and may detect occult tumour recurrence. Awareness of the cellular changes resulting from irradiation, and the varied composition of post-irradiation smears may lead to more accurate interpretation of the cytological findings.
