Figure 2 Summary estimates of hazard ratio (HR) for (A) disease recurrence and (B) death associated with hematogenous tumor cell detection. RFS, recurrence-free survival; OS, overall survival. Note: Three studies reported cancer-related survival (CRS) instead of OS.17,20,39 Sensitivity analysis excluding these studies did not change the results significantly (HR = 2.44 [95% CI: 1.60–3.74], n = 18, I2 = 67%).

Figure 3 Summary estimates of hazard ratio (HR) for disease recurrence and death associated with tumor cell detection in the (A and D) peripheral blood, (B and E) mesenteric/portal blood, and (C and F) bone marrow compartment. RFS, recurrence-free survival; OS, overall survival. Note: Two studies in the analysis of peripheral blood (D) reported cancer-related survival (CRS) instead of OS.17,20 Sensitivity analysis excluding these studies did not change the results significantly (HR = 2.73 [95% CI: 1.68–4.45], n = 14, I2 = 63%).
