Relationship between postoperative tumor recurrence time and long-term survival in colorectal cancer patients

Figure 1 Kaplan-Meier survival curves comparing early and late recurrence groups in colorectal cancer patients. A: Overall survival curves showing significantly worse prognosis in the early recurrence group (median 36.8 months) compared to the late recurrence group (median 68.5 months) (Log-rank P < 0.001); B: Post-recurrence survival curves demonstrating markedly shorter survival after recurrence in the early recurrence group (median 14.6 months) than in the late recurrence group (median 33.2 months) (Log-rank P < 0.001).
