Comparison of survival based on initial symptom severity and type of therapy. (A) Median overall survival time of patients based on New York Heart Association (NYHA) functional classification, where patients with NYHA class I or II at the time of diagnosis showed significantly better survival than those with a more severe functional class. (B) Median overall survival time of patients according to the treatment is shown. Patients with molecular targeted therapy showed significantly better survival than those with conventional therapy only.
