Abstract

In 1988 we started our investigation on the influence of low-level laser on oncologic patient. Now we have an experience of application of LLLT on more than 700 patients with the confirmed diagnosis of cancer at different stage. We used LLLT on 112 with stomach cancer 4th stage before and after operation and on patients without operating interference. LLLT investigations, with a wavelength of 890 nm, have shown that the laser therapy before operation is most effective. Laser therapy activates the immune system by increasing T-active rosette-formed cells and T-helpers and by decreasing T-suppressor cells. Application of LLLT decreases postoperative complications by 11.86 percent after palliative operations; by 9.63 percent after non-radical operations. It also promotes more rapid restorations of the motility and improves general status of patients by 58.69 percent. Investigations of low-level radiation have shown that the life-span of patients with 4th stage stomach cancer who were treated by laser therapy before surgery was increased by 2.03 percent; for those who were treated by LLLT after surgery it was increased by 1.81 times and by 3.03 times in those who took LLLT without surgery.
