There is a wealth of statistics regarding operations for cancer of the cervix uteri. Despite the figures obtained by radical operators like Wertheim, the vast majority of those surgeons who practise either vaginal or abdominal hysterectomy have obtained far inferior results to those of Byrne, with his cautery, which is still in use. Wertheim once reported the astonishing figure of 61 per cent of 5‒year recoveries. In a later report, however, Wertheim stated that only about one half of the cases that come to him are operable, and of these about one half are cured by operation, that is, about 25 per cent of all cases. But experience shows that if these cases could be followed up there would be very many late recurrences. The claims of Wertheim and others must be offset, however, by the high operative mortality reported by many; as the cases must have been incipient in order to be operable, it is possible that Byrne with his cautery could have done nearly as well, and Byrne never lost a patient. But Klein of Munich, by circular letters compiled many statistics, and concluded that the percentage of cure was but 4.5 per cent, and Klein himself obtained only 3.6 per cent. Reinecke asserted that only 10 per cent of cases of cancer of the cervix can be cured. Fredrick (_Trans. Gynæcol. Soc._, 1905, p. 136) collected the records of 500 hysterectomies for cancer of the cervix performed by prominent colleagues and himself. Of this entire material there had been but 13 five-year cures. In discussion Henrotin stated that he had practically given up abdominal hysterectomy. Currier stated that surgery was a failure as a cure for cancer. At an earlier session of the Society, 1900, in a discussion of Pryor’s paper, Van de Warker asserted that surgery had done nothing for cancer; Lapthorne Smith said that many women did better if left alone. J. Byrne stated that hysterectomy for cancer was a crime. Engleman thought that cancers left alone may insure a longer survival than those treated surgically. In a discussion before the same Society in 1896 (on Byrne’s paper) vaginal hysterectomy was discussed. While Boldt, Dudley, and Baldy claimed excellent results, Segond is known to have had but 5 relative cures (2‒5 years) in 80 cases. Mundé saw a rapid return in all his 25 cases. Polk had recurrence in every one of 50 cases. Byrne collected notes of 283 operations by ten men, and the results were as follows: died, 7 per cent; life prolonged, 11 per cent; and became worse, 82 per cent.
