THE EFFECTS OF ULTRA-VIOLET LASER RADIATION ON CANCER

Abstract

A group of mice implanted with squamous cell carcinoma (CA1025) and melanoma (B16) were irradiated with a cw krypton laser using 3374A° (total dosage 346 j/cm², and 660 j/cm²) , and 3507A° (total dosage 367 j/cm²), and a pulse N₂ laser 3371A° (total dosage 471 j/cm², 660 j/cm², and 165 j/cm²). In all groups, tumorous mice were used as controls.

Regression of tumors was observed at wavelengths of 3374A° and 3371A° (total dosage 471 j/cm² and 660 j/cm²). No regression was observed at 3507A°. The regression in some cases was very impressive.

The preliminary work on N₂ laser irradiation of basal cell carcinoma (in human beings) and of BEL 7404 liver carcinoma cells in vitro and irradiation of one patient with an N₂ laser performed in China will also be reported.
