Second exposure after one year by Dr. V. E. SILER showing operating room set up with laser, 70 joules exit energy Exposure of tumor in two centimeter deep mass became smaller. operating room ruby patient, this had been present for some five years without any evidence of metastases, In the other patient, there was a small metastatic nodule in the axilla. These lesions, in both of these patients, were exposed in the operating room by Dr. V. E. Siler, Director of Laser Surgery at the Laser Laboratory.

Laser Treatment of Melanomas 39 Multiple laser impacts, focussed and unfocussed, were given to the exposed tissues even to pigmented masses deep in the neck. The patients withstood the operations very well and during the brief period of observation, there were no significant reactions. Both patients were given in addition autogenous extracts of melanoma in complete Freund's adjuvant and adjuvant 65. In only follow-up of one year the lesions in both patients are not progressive. As yet, there are no visceral metastases in the laser impact area but there is are spread about the periphery.

The instrument must have a high output, be flexible and easily controlled by the surgeon, maintain sterility precautions and be safe for operation as regards electrical and anesthesia hazards. At present, our laser operating rooms have 650 joules exit energy ruby lasers, a laboratory model of an 1160 exit energy neodymium laser on loan from the Eastman Kodak Company and a 2-10 watt CW argon laser on loan from the Bell Telephone Laboratories. The ruby laser is flexible, not as yet under the direct control of the surgeon but able to be moved in all planes by the technician.
