What are the treatment options to increase survival rate in advanced adenocarcinoma of lung?

Survival: Tumor stage and tumor burden meaning what organs are involved and how much disease is there plays a role. Similarly tumor subtype adenocarcinoma, tumor profile egfr mutation or alk mutation can affect survival. Non smokers have better prognosis. For advanced stage, all measures are still considered palliative. Other factors such as general health, infections and thromboembolism can affect survival.
