Electroacupuncture Combined With PD-1 Inhibitor for Elderly Patients With Advanced NSCLC

"In the electroacupuncture group, bilateral Zusanli (ST36) and Sanyinjiao (SP6) points were selected for needling. Upon achieving the deqi sensation, the electroacupuncture device was connected to the needles at both points. A dispersed-dense wave was applied with an intensity ranging from 0.5 to 2 mA, adjusted according to the patient's tolerance. The needles were retained for 20 minutes, after which they were removed."

"In the sham electroacupuncture group, bilateral Zusanli (ST36) and Sanyinjiao (SP6) points were selected for sham electroacupuncture intervention, which did not receive manual manipulation. The electrode placement and other treatment settings were identical to those in the electroacupuncture group, but no skin penetration, electrical output, or needle techniques were applied to induce the sensation of deqi. No genuine electroacupuncture stimulation was administered in this group."
