Figure 1.
Comparison of progression-free survival (PFS) and overall survival (OS) between the carbon ion radiotherapy (CIRT) monotherapy group and the preoperative adjuvant chemotherapy (NAC) + curative surgery + adjuvant chemotherapy group before propensity score matching. (A) There is no significant difference in PFS between the CIRT monotherapy and the NAC + curative surgery + adjuvant chemotherapy group (p=0.733). (B) OS is better in the NAC + curative surgery + adjuvant chemotherapy group compared to the CIRT monotherapy group (p=0.006).

Comparison of progression-free survival (PFS) and overall survival (OS) between the carbon ion radiotherapy (CIRT) monotherapy group and preoperative adjuvant chemotherapy (NAC) + curative surgery + adjuvant chemotherapy group by propensity score matching. (A) There is no significant difference in PFS between the CIRT monotherapy and NAC + curative surgery + adjuvant chemotherapy groups (p=0.992). (B) OS is significantly better in the NAC + curative surgery + adjuvant chemotherapy group than in the CIRT monotherapy group (p=0.037).
