It is certain that cancer does occasionally attack a cervical stump left after subtotal hysterectomy at such an interval after the operation as to make it certain that the cancer did not exist at the time of the operation. Such a case occurred in my practice. I performed subtotal hysterectomy in 1901 on a woman forty-two years of age, mother of one child; eighteen months later there was a cancerous ulcer on the cervix; the whole of the cervical stump was promptly removed and the nature of the disease established microscopically. In 1908 the patient was in excellent health.
In another case under my care I performed total hysterectomy for fibroids in ignorance that the patient had cancer of the cervix. Some months after the operation cancer recurred in the vaginal vault and scar of the hysterectomy; the neck of the uterus had been preserved by the doctor, and on examination the cancer was found. In this instance, although total hysterectomy was performed, it had no effect in staying the course of the disease.
It is necessary to utter a caution in regard to the occurrence of cancer of the cervix after subtotal hysterectomy. I removed a uterus containing a large globular submucous fibroid from a barren married woman forty-five years of age. Six years later she came under my observation with a large granulating and bleeding growth on the cervix uteri. I had no doubt from the naked-eye characters that this was a primary carcinoma, although it surprised me to find it there, especially as the woman had never been pregnant. On my urgent representations she allowed me to remove the cervix. On microscopic examination the suspected cancer turned out to be a granuloma. Two years later the patient was in good health. Polk has recorded a similar experience. These facts show that caution is necessary in accepting reports of cancer of the uterine stump after subtotal hysterectomy.
=Cancer of the body of the uterus and fibroids.= In deciding between total and subtotal hysterectomy for fibroids the probable presence of cancer requires consideration in another aspect. Although uterine fibroids do not predispose to cancer of the neck of the uterus, many writers in recent years have expressed their suspicions that the presence of a submucous fibroid favours the development of cancer in the corporeal endometrium. Piquand, in 1905, drew attention to this matter and emphasized what other observers had pointed out, namely, that a submucous fibroid is often associated with changes in the mucous membrane of the uterus, which not only causes excessive bleeding, but sets up inflammatory conditions giving rise to leucorrhœa, salpingitis, pyosalpinx, and morbid changes in the endometrium, rendering it susceptible to cancer. His statistics support his conclusions, for they represent that in one thousand women with fibroids fifteen will probably have cancer of the body of the uterus. My own observations support this opinion. This complication is found most frequently between the fiftieth and the sixtieth year of life. If we narrow the ages of the patient and exhibit the liability in its most emphatic form it would run thus: that in patients submitted to hysterectomy for fibroids over the age of fifty years, about ten per cent of them will have cancer of the corporeal endometrium.
