Impact of renal insufficiency on patients with hepatocellular carcinoma undergoing radiofrequency ablation

Recurrence of hepatocellular carcinoma after radiofrequency ablation in a poor-risk patient with chronic renal failure and other complications successfully treated with stereotactic body radiotherapy

The patient was an 85-year-old man with hepatitis C-related liver cirrhosis and chronic renal failure caused by diabetes mellitus under maintenance hemodialysis (HD) who developed hepatocellular carcinoma (HCC) after achieving a sustained viral response with direct acting antiviral therapy 1 year and 3 months previously. HCC located near the right hepatic vein was treated by radiofrequency ablation (RFA) but recurrent disease accompanied by hepatic vein invasion was detected 3 months after RFA. The recurrent HCC was curatively treated with stereotactic body radiotherapy (SBRT). The patient had additional complications, including grade III AV block controlled by a pacemaker, colonic adenoma resected by endoscopic mucosal resection, and a small cerebral aneurysm, which was untreated. At 2 years after SBRT, there had been no recurrence of HCC. In this old HCC patient with various complications including HD with polypharmacy, multidisciplinary treatment, including SBRT, enabled the patient to achieve complete remission and maintain a good quality of life.

ALBI grade in dialysis patients with hepatocellular carcinoma: prognostic impact and staging strategy

BACKGROUND

Patients with hepatocellular carcinoma (HCC) may develop end-stage renal disease and receive dialysis, but the impact of dialysis on the prognosis is unclear. This study aimed to evaluate the outcome of dialysis HCC patients and the prognostic role of albumin-bilirubin (ALBI) grade in these patients.

METHODS

Among the consecutive 3,794 HCC patients between 2002-2017, 43 patients undergoing dialysis, and 129 age, sex-matched controls were analyzed. Multivariate Cox hazards model was used to identify independent prognostic predictors.

RESULTS

Dialysis patients had decreased overall survival when compared with non-dialysis patients (n=3,751) and matched controls (n=129; each P=0.004). Patients with ALBI grade 1 had the best survival in the pooled cohort of dialysis and matched controls (n=172). In the Cox model, total tumor volume >33 cm3 [hazard ratio (HR): 6.763, P<0.001], presence of ascites (HR: 6.168, P<0.001), dialysis duration less than 24 months (HR: 3.144, P=0.006), diabetes-related dialysis (HR: 9.366, P=0.001) and non-curative treatments (HR: 9.220, P<0.001) were poor prognosis factors associated with increase mortality among dialysis patients. Of the 9 currently-used HCC staging systems, the CLIP score was the optimal cancer staging for dialysis patients.

CONCLUSIONS

Patients receiving dialysis had decreased overall survival compared with non-dialysis patients. Longer duration of dialysis, non-diabetes related dialysis, absence of ascites, and curative treatments were associated with improved survival in these patients. The ALBI grade is a feasible prognostic model to evaluate liver functional reserve, and the CLIP model is the best staging system for dialysis patients with HCC.

Benefits and problems of transarterial therapy in patients with hepatocellular carcinoma and chronic kidney disease

PURPOSE

To evaluate the feasibility of transarterial therapy (transcatheter arterial chemoembolization and transcatheter arterial infusion) for patients with hepatocellular carcinoma and chronic kidney disease (CKD).

MATERIALS AND METHODS

The study enrolled 35 patients who received transarterial therapy. The patients were classified into a CKD group (n = 10 nondialysis chronic kidney disease [NDCKD] and n = 9 end-stage renal disease [ESRD]) or a non-CKD group (n = 16). The survival rates between the two groups were compared using two different starting points: (a) from initial diagnosis of hepatocellular carcinoma and (b) from enrollment in the study. The tolerance of transarterial therapy in patients with CKD was evaluated by comparing the incidence of major adverse events.

RESULTS

The 2-year and 5-year survival rates from initial diagnosis were 83.9% and 53.8% in the CKD group and 70.1% and 40.4% in the non-CKD group (P = .478). The corresponding 3-year survival rate from enrollment in the two groups was 25.6% and 41.2%, respectively (P = .995). The 2-year and 5-year survival rates from initial diagnosis were 70.1% and 40.4% in the non-CKD group, 90.0% and 39.4% in NDCKD patients, and 76.2% and 76.2% in ESRD patients (P = .380). The corresponding 2-year survival rates from enrollment in these groups were 54.9%, 48.0%, and 48.6% (P = .943). Severe contrast-induced nephropathy (n = 3) and late-onset death caused by cholesterol crystal embolism (n = 1) were observed in the NDCKD group.

CONCLUSIONS

Transcatheter arterial chemoembolization is feasible in patients with CKD by instituting periprocedural hemodialysis with similar 2-year and 5-year survival compared with patients without CKD.
