A Case of Stereotactic Radiotherapy (SRT) of Multiple Squamous Cell Lung Cancer

Abstract

A 70-year-old man was hospitalized with productive cough since one month previously. Multiple squamous cell carcinomas were found in right S^1 the orifice of the right upper lobe bronchus, right basal lobe bronchus and left upper lobe bronchus. The orifice of the right upper bronchus, the right basal lobe bronchus and the left upper lobe bronchus contained carcinoma in situ. Tumors of the right S^1 and the orifice of the right upper lobe bronchus were removed by sleeve lobectomy. Metastatic mediastinal lymph nodes were not found. The lesions of the orifice of the right basal bronchus and in the left upper bronchus were treated by stereotactic radiotherapy (SRT). There was no severe complication, and the effect obtained was complete response (CR). SRT is considered to be effective therapy for multiple carcinomas, especially, early lung cancer lesions such as carcinoma in situ.
