PG2 Breast Cancer Evaluation in Adjuvant Medicine-Survival Study

Overview

Astragalus polysaccharides (APS), acting as an immunomodulator, is known to modulate the tumor microenvironment and inhibit tumor growth and progression, thereby suggesting potential as an adjuvant cancer therapy to improve treatment outcomes. PG2 (APS Injection) has completed a clinical trial (Protocol name: PG2 Treatment for Reduction of Chemotherapy-Induced Toxicity and Encouraging Compliance with Chemotherapy among Stage II/III Breast Cancer Patients Receiving Adjuvant Chemotherapy , NCT03314805, hereinafter called the parent trial) aimed to show that PG2 treatment among stage II/III breast patients under adjuvant Epirubicin and cyclophosphamide (EC) regimen in reduction of chemotherapy-induced toxicities and encouraging compliance with chemotherapy. This study will further explore whether the addition of PG2 can delay cancer recurrence or metastasis, thereby conferring substantial survival benefits for early breast cancer patients with adjuvant chemotherapy by retrospectively collecting recurrence, metastasis, and survival information from patients enrolled in the parent trial.
