Abstract

OBJECTIVE

This study aimed to investigate clinical characteristics and prognosis of secondarily developed lung tumors in the cases having different system malignancy and to evaluate the relationship with the primary tumor.

METHODS

Between January 2002- December 2010 thirty patients diagnosed as second primary lung cancer have been included in the study. The patients were grouped according to lung cancer development time; synchronous group (n: 7 patients, 16.7%) and metachronous group (n: 23 patients, 83.3%).

RESULTS

Second cancer was detected in 50% of the patients within the first 2.5 years. Majority of patients had extra pulmonary cancer history concerning their relatives (43.3%). The rate of quitting smoking among all patients before the diagnosis of lung cancer was 50 %, current smoker rate was 30 % and never smoker was 20%. There was no statistical relationship between the response to treatment of first cancer and the duration of cancer developed secondarily (p=0.36). The overall survival of groups was found 24 months (95% confidence interval: 18.30 months) and 12 months (95% confidence interval: 10-14 months) respectively for synchronous and metachronous groups.

CONCLUSION

Close follow-up on pulmonary system especially within the first 2.5 years after primary disease and encouragement on quitting smoking is important.
