Supravaginal uterine amputation in Denmark 1978-1988 and risk of cancer.
In Denmark, total rather than subtotal hysterectomy has been recommended as treatment for benign conditions of the uterine corpus, primarily due to the risk of cervical cancer in the residual stump. Due to possible benefits during and after surgery, it has recently been argued that total hysterectomy for benign conditions could be substituted by subtotal hysterectomy, particularly since cancers of the cervix are declining as a consequence of screening. Cancer risk following supravaginal uterine amputation among 1104 Danish women undergoing operations during 1978-1988 was studied using record linkage techniques with the Danish Cancer Registry. No overall cancer risk, nor an overall increased risk of cancers coded as cervical, was observed. However, a 3.3 to 5.0-fold increased risk for cervical cancer was observed among women whose operations occurred at 50 years of age or older, possibly reflecting an increased risk of cancer in the endocervical area or in remaining uterine tissue. This observation, together with the difficulties in treating a cervical cancer of the stump when it does occur, should be taken into account before a change in surgical procedures from total to subtotal hysterectomies is recommended.
