Effect of microsurgical and carbon dioxide and argon laser resection on recurrence of the intracerebral 9L rat gliosarcoma.
The intracerebral 9L rat brain tumor was resected from 38 rats with the use of standard microsurgical techniques, the carbon dioxide laser, or the argon laser. The extent of resection was evaluated by histological examination, and the effect on survival of the three methods was compared. All three methods achieved histologically verifiable gross total resection, and tumor recurrence after resection by all three methods occurred at the same rate.
