BAI-BACE for Advanced Lung Squamous Cell Carcinoma

This study is a multicenter, interventional study to explore the efficacy, safety of BAI-BACE as non-first-line therapy for advanced central squamous cell carcinoma. Lung cancer is the leading cause of cancer-related death worldwide. Owing to the insidious symptom, most patients (about 75 %) are diagnosed at the advanced stage of the disease and, thus, cannot undergo resection. The central squamous cell carcinoma accounts for 25% of all cases of lung cancer. The first-line standard treatment for advanced central squamous cell carcinoma is combined chemoradiotherapy, and chemoradiotherapy is usually as the second-line. However, treatment failure is noted in many patients, and those patients often face the limited therapy choice and poor prognosis. Bronchial arterial infusion plus bronchial arterial chemoembolization (BAI-BACE) has been reported to treat lung cancer in many hospitals in China. BAI, which use chemotherapeutic drugs directly injected into the tumor and achieved a high concentration in a short time to kill the tumor. Then BACE could seal off the tumor vessels. The systemic toxicity of this surgery is low and tolerable. This study will provide clinical evidence that BACE-BAI will provide survival benefit for patients with advanced central squamous cell carcinoma.
