DURING the 25-year period 1928-1953 there were 1,498 cases of cancer of the larynx seen in the bronchoscopic clinic of the Jefferson Hospital. Of this number, 1,442 were verified histologically. Fifty-eight of the patients had two or more primary lesions. Although there are many variable factors encountered in any large series of cases, some can be eliminated in this group, since all the records have been kept in a uniform manner for the entire period and the management of the patients has been under the direction of one person, Dr. Louis H. Clerf. It is extremely hazardous to attempt to arrive at any final decisions on the basis of data from one source. This report serves to place statistical material on record so that, when considered with that from other sources, more knowledge of laryngeal carcinoma may be gained. No valid statistical conclusions about the disease can be drawn from |
