Kong Fanming120 enrolled

Overview

The aim of this study was to systematically evaluate the clinical efficacy and safety of electroacupuncture (EA) combined with PD-1 inhibitors in patients with advanced non-small cell lung cancer (NSCLC) who have an ECOG performance status of 2 through a multicenter, randomized, sham-controlled clinical trial. The core scientific question addressed in this study was whether EA combined with standard immunotherapy could further improve progression-free survival (PFS), immune function, and quality of life in these patients. Patients meeting the inclusion criteria were randomly assigned in a 1:1 ratio to receive EA plus a PD-1 inhibitor (trial group) or sham EA plus a PD-1 inhibitor (control group) through a computerized randomization system. PD-1 inhibitors were administered every 21 days for four to six cycles, followed by maintenance therapy according to each patient's condition. EA intervention was initiated on the first day of each immunotherapy cycle and administered once daily for five sessions per cycle, continuing for four to six cycles. The primary endpoint was progression-free survival (PFS). The secondary endpoints included objective response rate (ORR), overall survival (OS), first-line treatment completion rate, quality of life as assessed by the EORTC QLQ-C30 scale, traditional Chinese medicine (TCM) syndrome score, immune function index, and incidence of adverse events according to CTCAE 5.0 criteria. In addition, peripheral blood was collected from patients at baseline for non-coding RNA sequencing, and differentially expressed genes were identified through bioinformatics analysis to determine potential molecular biomarkers associated with the synergistic effects of EA, thereby providing a basis for accurately identifying patients likely to benefit from EA therapy.

Based on the principles of evidence-based medicine, a randomized controlled clinical trial was conducted to provide high-quality evidence on the clinical efficacy and immunomodulatory effects of acupuncture combined with first-line immunotherapy in patients with advanced NSCLC with an ECOG PS2, thereby facilitating the promotion and application of "precision" traditional Chinese medicine (TCM) treatment. This project provides an evidence-based reference for developing standardized treatment protocols and clinical pathways for advanced NSCLC and further clarifies the potential role of TCM within the therapeutic framework of advanced lung cancer, holding significant academic value and substantial social benefits.

Interventions

Electroacupuncture (EA)OTHER

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.

Sham electroacupunctureOTHER

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.
