Prognosis
In limited stage disease, median survival with treatment is 14–20 months, and about 20% of patients with limited stage small cell lung carcinoma live 5 years or longer.
The prognosis is far worse in extensive stage small cell lung carcinoma, with treatment, median survival is just 8–13 months, and only 1–5% of patients with extensive stage small cell lung carcinoma treated with chemotherapy live 5 years or longer.
