clinical study of propranolol combined with neoadjuvant chemotherapy in gastric cancer

Conditions: Gastric Cancer

Summary: at the cellular and animal level, we found that propranolol can inhibit the proliferation and invasion of gastric cancer cells. further, we want to explore the efficacy and safety of propranolol in the treatment of gastric cancer patients.
