辅助化、放疗相关的生存曲线。A：行术后辅助化疗与未行术后辅助化疗患者的生存比较显示，未行术后辅助化疗患者预后相对较好（P < 0.001）；B:行术后辅助放疗与未行术后辅助放疗患者的生存比较显示，二者生存无差异（P=0.538）；C：MG患者术后行辅助化疗与未行术后辅助化疗的生存比较显示，二者生存无差异（P=0.150）；D: MG患者术后行辅助放疗与未行术后辅助放疗的生存比较显示，二者生存无差异（P=0.424）。

Survival curve associated with adjuvant chemotherapy and adjuvant radiotherapy. A: The survival of patients who received adjuvant chemotherapy and without adjuvant chemotherapy showed that the prognosis of patients who did not undergo adjuvant chemotherapy was relatively good (P < 0.001); B: Survival comparison between adjuvant radiotherapy and postoperative adjuvant radiotherapy in patients showed that there was no difference in survival between the two groups (P=0.538); C: Survival comparison between adjuvant chemotherapy and non adjuvant chemotherapy after MG showed that there was no difference in survival between the two groups (P=0.150); D: Survival comparison between adjuvant radiotherapy and postoperative adjuvant radiotherapy in MG patients showed that there was no difference in survival between the two groups (P=0.424).
