Purpose Treatment response to drug-eluting bead chemoembolization (DEB-TACE) is well established for patients with hepatocellular carcinoma (HCC); however, few studies have evaluated tumor imaging characteristics associated with treatment responses. The aim of our study was to identify imaging characteristics associated with treatment responses and overall survival after DEB-TACE of HCC. Methods This is a retrospective cohort study of 33 tumors in 32 patients who underwent DEB-TACE for inoperable HCC in a single, large academic medical center. Arterial phase computed tomography data were reviewed to assess tumor size, edge characteristics, tumor enhancement on pixel density histogram, and heterogeneity using coefficient of variation. We assessed correlation between these markers of tumor morphology and response to DEB-TACE using mRECIST criteria, progression-free survival, and overall survival. Results Tumor heterogeneity (P = 0.01) and tumor enhancement greater than 50% (P = 0.05) were significantly associated with complete response to DEB-TACE in patients with HCC; however, neither was associated with overall or progression-free survival. Tumor size and edge characteristics were not associated with complete response to DEB-TACE, although tumor size greater than 6 cm was associated with worse overall survival (hazard ratio, 3.349; P = 0.02). Conclusions Tumor heterogeneity and enhancement on arterial phase imaging may be predictive markers of treatment response to DEB-TACE among patients with HCC.

Uveal melanoma is one of the most common primary intraocular malignancies that accounts for about 85% of all ocular melanomas. The pathophysiology of uveal melanoma is distinct from cutaneous melanoma and has separate tumor profiles. The management of uveal melanoma is largely dependent on the presence of metastases, which confers a poor prognosis with a one-year survival reaching only 15%. Although a better understanding of tumor biology has led to the development of novel pharmacologic agents, there is increasing demand for minimally invasive management of hepatic uveal melanoma metastases. Multiple studies have already summarized the systemic therapeutic options available for metastatic uveal melanoma. This review covers the current research for the most prevalent locoregional treatment options for metastatic uveal melanoma including percutaneous hepatic perfusion, immunoembolization, chemoembolization, thermal ablation, and radioembolization.

To compare the safety and efficacy of percutaneous ultrasound guided gastrostomy (PUG) tube placement with traditional fluoroscopic guided percutaneous gastrostomy tube placement (PRG). A prospective, observational, non-randomized cohort trial was performed comparing 25 consecutive patients who underwent PUG placement between April 2020 and August 2020 with 25 consecutive patients who underwent PRG placement between February 2020 and March 2020. Procedure time, sedation, analgesia requirements, and complications were compared between the two groups in non-inferiority analysis. Technical success rates were 96% in both groups (24/25) of procedures. Ninety-two percent of patients in the PUG cohort were admitted to the ICU at the time of G-tube request. Aside from significantly more COVID-19 patients in the PUG group (P < .001), there was no other statistically significant difference in patient demographics. Intra-procedure pain medication requirements were the same for both groups, 50 micrograms of IV fentanyl (P = 1.0). Intra-procedure sedation with IV midazolam was insignificantly higher in the PUG group 1.12 mg vs 0.8 mg (P = .355). Procedure time trended toward statistical significance (P = .076), with PRG being shorter than PUG (30.5 ± 14.1 minutes vs 39.7 ± 17.9 minutes). There were 2 non-device related major complications in the PUG group and 1 major and 1 minor complication in the PRG group. PUG is similar in terms of complications to PRG gastrostomy tube placement and a safe method for gastrostomy tube placement in the critically ill with the added benefits of bedside placement, elimination of radiation exposure, and expanded and improved access to care.

Pulmonary embolism (PE) is a leading cause of morbidity and mortality worldwide. PE is a complex disease with a highly variable presentation and the available treatment options for PE are expanding rapidly. Anticoagulation (AC), systemic lysis, surgery, and catheter-directed thrombolysis (CDT) play important roles in treating patients with PE. Thus, a multidisciplinary approach to diagnosis, risk stratification, and therapy is required to determine which treatment option is best for a given patient with this complex disease.
