there is not only overgrowth and invasion of myometrium by glandular tissues in groups and bundles as in the above cases, but there is destruction of the basement membrane and invasion and infiltration into the stroma and lymphatics of cancer cells individually and in strands, columns and cellular masses. Often indeed there is such an extensive cellular overgrowth that almost all evidence of gland structure is absent. These cases are distinctly more malignant histologically and clinically than those of the first group. Even with a relatively short history, less than six months, they may be incurable because of local and distant metastases. (Fig. 2.) In reviewing our cases in 1930 it seemed to us that our end results were poorest in the group of adenocarcinoma cases treated by hysterectomy without irradiation and

exclusively. In an effort to acquire additional information on this point we have quite uniformly subjected most of our cases of cancer of the corpus to irradiation before the hysterectomy is done. The irradiation, since most of the patients are beyond the menopause consists of a pelvic x-ray therapy cycle of 750 r or 1000 r given to each of four pelvic fields. This is given in daily doses, usually divided, and using a 200 k.v. machine. A week or ten days after completing the x-ray therapy cycle, a diagnostic curettage is done and radium capsules are inserted into the corpus and cervix for an average dose of 3600 milligram hours. If hysterectomy is planned to follow the irradiation it is usually done four to ten weeks later.

of endometrial cancer. Whether it is more than coincidence is difficult to say since uterine fibromyomata are extremely common and cancer of the corpus is rather infrequent in comparison. However, it seems to me of the utmost importance to do a diagnostic curettage to rule out endometrial cancer in all cases of uterine bleeding associated with fibromyomata when the patients are over forty-five years of age, before resorting to hysterectomy. If the curettage reveals tissue grossly resembling cancer, intrauterine radium and if feasible x-ray therapy should be promptly instituted and the hysterectomy temporarily postponed. In possibly one of every 3 cases treated by irradiation followed four to ten weeks later by hysterectomy, the pathologist will find evidence of persistent cancer in the removed uterus. Often this is said to show marked irradiation changes and to be nonviable. Nevertheless the uncertainty associated with such findings makes it absolutely

essential for us to follow with close observation for at least a year each and every patient in whom treatment for the cancer is limited to irradiation. If uterine discharge or bleeding should again be observed three or four months or longer after radiation treatment, a second diagnostic curettage should be done and if cancer is found intrauterine irradiation should be repeated and, if at all feasible, hysterectomy should follow the second course of radiation treatment. CONCLUSIONS
I t is evident from this discussion that, based upon our experience and observation at the Memorial Hospital in the care of patients suffering from primary cancer of the corpus, the writer believes that adequate radiation therapy alone in the less favorable cases or preliminary to panhysterectomy in the surgically operable cases lways should be the routine procedure.
