Lung cancer is one of the leading causes of death worldwide. Lung cancer treatment are including surgery, chemotherapy, targeted therapy and radiotherapy. Despite therapy modalities mentioned above, lung cancer survival is remained poor. In this research we want to find out the correlation between the current treatment modalities used and the survival of lung cancer patients.

Data will be analyzed regarding the correlation between the therapy given and survival of the patients also the correlation between histologic types of lung cancer and therapy given using contingency coefficient. Coefficient we found weak correlation between cancer type and therapy modalities given (p<0.01 and C=0.301) where targeted therapy is related with adenocarcinoma. Moderate correlation between therapy given and survival of the patients (p<0.01, C=0.533). Targeted therapy related with better survival outcome compared to chemotherapy and patient that get only supportive care. Targeted therapy is related with better prognosis compared to chemotherapy and supportive care. Targeted therapy drugs that used in Adenocarcinoma found in this research is mainly targeting EGFR mutation.
