Fig. 4From: Cellular immunotherapy as maintenance therapy prolongs the survival of the patients with small cell lung cancerThe influence of cellular immunotherapy (CIT) courses on small cell lung cancer (SCLC) patients’ prognosis. (A) The median progression free survival (PFS) in the CIT ≥ 3 courses group was longer than that of the CIT < 3 courses group (9.5 vs. 2 months), although this difference was not significant (P = 0.057). (B) The median overall survival (OS) in the CIT ≥ 3 courses group was significantly longer than that of patients in the CIT < 3 courses group (23 vs. 9 months; P = 0.020)Back to article page
