Abstract

Synchronous and metachronous lung cancer is occasionally encountered. Frequency of the occurrence is increasing because of recent progress of imaging technique such as high resolution CT and CT based annual lung survey. We analyzed clinical characteristics of both synchronous and metachronous lung cancer treated surgically in our facility. There were 20 cases of multiple lung cancer cases, which is consisted of 12 synchronous multiple lung cancer cases and 8 metachronous lung cancer cases. Mean age was 62 years old and there were 14 male and 6 female cases. Among synchronous group, 8 cases have multiple shadow in ipsilateral hemithorax and 4 cases in both side. Surgery was carried out according to the extent of the disease and lung reserve. Associated cancer was diagnosed stage IA or IB in all cases. Five-year survival was 58.9%. Meanwhile, as regards to metachronous group, mean interval between first cancer and second cancer was 73 months. Seven cases have contralateral second primary lung cancer and one case has ipsilateral second primary lung cancer. In 3 cases, histology of the first and the second disease were different and in 5 cases that were the same. The first procedures were complete resection with systemic mediastinal LN dissection. The second procedures were determined based on the lung reserve. Pathological stage of the second disease were either stage IA or IB. There were no operative mortality and 5 years survival was 75%. Since there is no operative mortality and the outcome seems satisfactory when the patient has enough lung reserve, aggressive surgical resection should be considered in the case of multiple primary lung cancer. There is an increasing chance of synchronous multiple primary lung cancer because of improvement of imaging system. We have to prepare new therapeutic strategy for those patients.
