INTRODUCTION: The alfapump system has been shown to be a possible alternative to repeat therapeutic paracentesis (TP) in selected patients with refractory ascites (RA). The objective of this study was to assess the safety and efficacy of alfapump on ascites control and quality of life in these patients. METHODS: Patients with cirrhosis and RA requiring ≥2 TPs 30 days prior were enrolled and followed for 24 months postimplant. Primary efficacy end point assessed at 6 months was reduction in paracentesis requirement; safety end point was device-related adverse events resulting in intervention, explant, or death. RESULTS: Forty patients with RA (mean Model of End-stage Liver Disease-Sodium: 15 ± 4) received an alfapump. TP requirement was decreased from 3.2 ± 1.5 sessions per month preimplant to 0.2 ± 0.6 sessions per month at 6 months postimplant ( P < 0.001), with 77% of patients having ≥50% reduction. Six pumps (15%) were explanted within 6 months due to device-related adverse events, 3 (7.5%) due to pump site skin erosion, and 3 (7.5%) due to bladder discomfort. Twenty-four renal events occurred in the 0–6 month postimplant period; 16 cases were readily reversible stage 1 acute kidney injury. Ascites-related symptoms assessed with an Ascites Q score improved from 51.0 ± 19.3 preimplant to 32.2 ± 21.9 at 6 months postimplant ( P < 0.001). Physical but not mental components of Short Form 36 improved ( P < 0.001). The 5 deaths within 6 months postimplant were not directly related to the device or alfapump therapy. DISCUSSION: The alfapump system effectively controlled ascites, which improved quality of life. It may be considered as an alternative to repeat TP in select patients with RA. Complication rates were similar to those expected in patients with RA.

Abstract Background and Aims Immunotherapy has emerged as an effective treatment for patients with advanced‐stage HCC. We aimed to investigate the efficacy of immunotherapy for advanced HCC in a nationwide cohort and racial and ethnic disparities in access to immunotherapy. Approach and Results We used the US National Cancer Database to identify patients with tumor‐node‐metastasis stage 3 or 4 HCC between 2017 and 2018. We performed multivariable Cox regression to identify factors associated with overall survival (OS) and logistic regression to identify factors associated with receipt of immunotherapy. Of the 3,990 patients treated for advanced HCC, 3,248 (81.4%) patients received chemotherapy and 742 (18.6%) patients received immunotherapy as a first‐line treatment. Immunotherapy was associated with improved OS compared with chemotherapy (adjusted HR: 0.76, 95% CI: 0.65–0.88) after adjusting for covariates. There were racial and ethnic disparities in access to immunotherapy, with Hispanic (adjusted OR [aOR]: 0.63, 95% CI: 0.46–0.83) and Black patients (aOR: 0.71, 95% CI: 0.54–0.89) less likely to receive immunotherapy compared with White patients. There was a significant interaction between race‐ethnicity and facility type, with higher disparity observed in nonacademic centers (interaction p = 0.004). Conclusions Immunotherapy was associated with improved OS compared with chemotherapy in advanced HCC. There are significant disparities in early access to immunotherapy, likely due to differential access to clinical trials and experimental therapies. A comprehensive approach to monitoring and eliminating racial‐ethnic disparities in the management of advanced HCC is urgently needed.
