Abstract: Kanglaite (KLT) injection, composed of coix seed oil, functions by supplementing qi and nourishing yin, which reduces swelling and eliminates stagnation in traditional Chinese medicine. KLT injection has been used mainly in the clinical treatment of advanced-stage non-small cell lung cancer, whether alone or in combination with chemotherapy. Studies confirmed that KLT injection combined with chemotherapy or targeted therapy for non-small cell lung cancer patients can enhance the clinical efficacy, reduce side effects, and improve the patients' quality of life.
