[Animal experiment comparison of the therapeutic efficacy of tumor excision with a scalpel or with a CO2 laser in subcutaneously implanted Lewis lung cancer].

Abstract

An animal experimental study was carried out in order to compare the therapeutical value of two different surgical methods for excising the subcutaneous implanted Lewis lung carcinoma - tumor excision with scalpel or with carbon dioxide laser. The radicalism of operation methods, the survival time, and the tumor local recurrences were performed. The therapeutic effectivity of tumor excision with the carbon dioxide laser is more favourable than the scalpel method.
