Supervoltage Roentgentherapy

This book is a valuable, detailed, well written and amply illustrated record of work done with an x-ray machine delivering roentgen rays with energies from 200 to 800 kv. The results in carcinoma of the esophagus, the maxillary sinus, the larynx, the urinary bladder, the breast and the cervix uteri, in malignant tumors of the pharynx and in pituitary adenoma are described. Of special interest are the favorable results in otherwise inaccessible esophageal tumors and the technical hints gathered from the work with the hypophysial tumors. Of interest also are the reasons given by the authors (page 200) for omitting postoperative radiation after a carefully done radical operation for carcinoma of the breast, and, finally, their general conclusion that promise of future advances lies not so much in exploring the region of higher voltages as in that close cooperation whereby the treatment is adapted as precisely as possible to the
