Fig 3. Overall survival (OS) rates of patients who did not receive previous chemotherapy and patients who received GC chemotherapy.

Fig 3

The OS rates since disease onset were 87.5% and 90.0% at 6 months, 87.5% and 67.5% at 1 year, and 36.5% and 40.5% at 2 years in patients who did not receive previous chemotherapy and those who received GC chemotherapy, respectively. The median OS since disease onset was 21.4 months (95% confidence interval [CI] 13.7–29.18) and 19.7 months (95% CI 9.84–29.63), respectively. There was no significant difference in the OS since disease onset between patients who underwent no chemotherapy and those who underwent prior GC chemotherapy (P = 0.661).
