Abstract:
introduction: Accurately predicting the outcomes of con-version therapy among patients with initially unresectable hepatocellular carcinoma (uHCC) remains a challenge. Clinical complete response (cCR) has been proposed as a predictor of prognosis. However, information on its prog-nostic value in these patients is limited. We aimed to explore the prognostic value of cCR in patients with uHCC following conversion therapy and identify predictors of cCR. Methods: We included 241 patients with uHCC who underwent transcatheter arterial chemoembolization combined with Lenvatinib and PD-1 inhibitors (triple therapy) as first-line treatment. The prognostic value of cCR, predictive factors ofcCR, and the relationship between cCR and pathological complete response (pCR) were analyzed. Results: The cCRrate of the 241 patients included was 17.4%. Patients with cCR showed better overall survival (OS) (p<0.001) and progression-free survival (PFS) (p<0.001) than those without. cCR was an independent risk factor for OS (hazard ratio [HR]: 0.11, 95% confidence interval [CI]: 0.03-0.42,p=0.001) and PFS (HR: 0.29, 95% CI: 0.15-0.56,p<0.001). Serum alpha-fetoprotein levels >= 400 ng/mL (odds ratio [OR]: 0.47, 95%CI: 0.22-0.95,p= 0.040) and extrahepatic metastasis (OR:0.13, 95% CI: 0.01-0.62,p= 0.046) were independent negative predictors of cCR. A total of 107 patients (44.4%)underwent conversion surgery. Among these patients, cCR was associated with better OS (p= 0.009) and recurrence-free survival (p= 0.007). cCR was significantly correlated withpCR (Phi= 0.61,p<0.001). Albumin levels >= 35 g/L (OR: 0.12,95% CI: 0.02-0.69,p= 0.018) and cCR (OR: 30.32, 95% CI:9.19-128.00,p<0.001) were independent predictors of pCR. Conclusion: cCR after triple therapy has an excellent long-term survival advantage and is significantly related to pCR.cCR may be a surrogate marker for predicting prognosis andpCR in patients with uHCC receiving triple therapy
