Abstracts from Literature Synopsis:This pilot study was performed to evaluate the effectiveness of bronchial artery infusion (BAI) of chemotherapeutic agents as a treatment for centrally located early-stage lung cancer. Seven patients with centrally located early-stage squamous cell lung carcinoma diagnosed bronchoscopically were offered BAI with cis-diamminedichloroplatinum (CDDP: dosage 50 to 150 mg/body, 35 to 100 mg/m2) as a curative attempt. All patients showed complete remission within 1 to 6 weeks after BAI. Three patients developed severe bronchial ulcers as a complication of BAI.
