A case of synchronous double lung cancer treated with right upper lobectomy and carbon ion radiation

Abstract

A 66-year-old man was found to have a mass shadow in the right upper lung field and underwent further examinations, which revealed a 35 mm squamous cell carcinoma (SCC) in the periphery of the right S² and a nodular, endoscopically-early SCC at the orifice of the right B⁷. He was diagnosed as having synchronous double lung cancer and underwent right upper lobectomy with mediastinal lymph node dissection for SCC in the right S², and the pathological stage was II B (pT3N0M0). Three months after surgery, carbon ion radiotherapy with 61.2 GyE was performed for another SCC at the bifurcation of the right B⁷, resulting in CR. He is presently alive with no evidence of recurrence 5 years and 3 months after surgery. Heavy ion radiotherapy is superior in terms of the local control of multiple lung cancer,and is considered to be one of the radical treatment options for secondary cancer.
