=Treatment.=--Complete removal of the uterus is the only curative treatment for cancer of the cervix. If the disease is seen in the earliest stages, amputation of the cervix beyond the limits of the growth seems, theoretically at least, to be a proper plan of treatment. Practically, however, the operator can never be certain that the excision is made in healthy tissue. The senses of touch and unaided sight are not capable of defining the limits of malignant infiltration. Moreover, it must be remembered that the endometrium is very often involved secondarily from a cancerous focus in the cervix. Complete removal of the uterus should therefore always be practised in all cases in which there is a possibility of removing all of the disease. The manner of performing this operation will be described subsequently. The cases that are not suitable for the operation of hysterectomy are those in which the disease has extended to structures that are surgically inaccessible. Such cases include those in which the bladder or the rectum are involved, those in which the vagina is extensively implicated, and those in which the disease has extended into the broad ligaments or the cellular tissue of the pelvis. When the bladder is involved, there are dysuria, vesical pain, and tenderness on vaginal pressure upon the base of the bladder, while the urine is altered in character, containing blood, pus, and, in the later stages, broken-down necrotic tissue. Involvement of the rectum is manifest by digital examination. When the broad ligaments are involved the uterus is held rigidly in the pelvis or is drawn to one side, and the bases of the broad ligaments, palpated through the lateral vaginal fornices, are thick and hard. When the cellular tissue of the pelvis is generally involved the whole vaginal vault feels indurated and the uterus seems fixed in the unyielding matrix. In examining with the view of determining the practicability of hysterectomy, it is important to distinguish between cancerous and simple inflammatory involvement of the broad ligaments. The uterus may be fixed in the pelvis by inflammatory adhesions resulting from old tubal disease, and yet the cancer of the cervix may be strictly local and in a stage suitable for hysterectomy. In the simple inflammatory cases the adhesions are more attenuated, are higher in the pelvis, and lie chiefly posterior to the uterus. They are not directly continuous with the cervix. Frequently the enlarged tube and the adherent ovary may be felt. When the uterus is fixed by cancerous involvement of the broad ligament, we readily feel that it is the base of the broad ligament that is involved. The induration is broad, it is directly continuous with the induration of the cervix, and it lies to the side of the uterus.
