RESUMO

PURPOSE: To compare retrospectively the safety and efficacy of yttrium-90 ((90)Y) radioembolization with the safety and efficacy of chemoembolization in patients with unresectable hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Survival and complication rates were evaluated for patients with HCC who underwent chemoembolization or radioembolization at a single institution between August 2007 and April 2010. Complications were graded according to a standardized grading system for embolization procedures. Survival was determined via the Kaplan-Meier method, and multivariable analysis for factors affecting survival was performed. RESULTS: This study included 73 patients with HCC who underwent index embolization with radioembolization (n = 38; 52.1%) or chemoembolization (n = 35; 47.9%). The two patient populations were similar in terms of demographics, etiology of cirrhosis, functional status, tumor characteristics, Child-Pugh class, previous liver-directed therapy, and number of patients with bilirubin > 2.0 mg/dL. There was no significant difference in survival between the radioembolization (median 8.0 months) and chemoembolization (median 10.3 months) cohorts (P = .33). Postembolization syndrome was significantly more severe in patients who underwent chemoembolization, which led to increased total hospitalization rates in these patients. The rates of other complications and rehospitalization were similar between groups. Increased age, Child-Pugh class B, hepatitis seropositivity, bilobar tumor distribution, tumor vascular invasion, and presence of extrahepatic metastases were associated with reduced patient survival. CONCLUSIONS: Patients treated with radioembolization did not show a survival advantage over patients treated with chemoembolization. However, patients who underwent chemoembolization had significantly higher rates of hospitalization as a result of postembolization syndrome.

RESUMO

Asymptomatic incidental thyroid nodules (thyroid incidentalomas) are found in up to a third of the adult population. There is notable overlap in the sonographic appearance of benign and malignant thyroid nodules. This paper provides a brief review of the ultrasound findings of thyroid nodules that are suspicious for malignancy with pathologic correlates. We then discuss the standard approach to a fine needle aspiration biopsy of a thyroid nodule at our institution. Finally, we review specific diagnostic challenges in image guided fine needle aspiration biopsies.

RESUMO

UNLABELLED: Whether provider education changes practice for HF has not been reported. (NHeFT)™ uses didactic and experiential training of primary care providers (PCP) to optimize treatment of HF. We randomized PCP's in the Cleveland VA clinics to training (T) vs control (C). ENDPOINTS: Primary - the number of patients with EF < 40% treated with ACEI/ARB and Beta Blocker, +/- diuretic post T vs pre T; Secondary - the number of patients with increase in ACEI/ARB or a decrease in diuretic post T vs. pre T. Of 641 patients, 216 (85 C,131 T) had EF < 40%; 188 (85%) did not meet the primary endpoint at baseline. After T, a similar proportion (64.2% C, 74.4%,T) met the endpoint at end of study (P = 0.14). The odds of a patient meeting the primary endpoint by care of a T provider, was not significantly higher than C (OR 1.496, 95% CI (0.751, 2.982)). Patients seen by T were more likely to have the diuretic dose decreased vs patients under C, without increases in ACEI or ARB (P < 0.03). Thus, a didactic program of HF plus a preceptorship changed practice modestly. Studies should address provider readiness of change and self efficacy to adhere to evidenced-based care.

RESUMO

BACKGROUND: Neuroendocrine liver metastases have a distinct tumor biology and symptomatology that render their management challenging. This difficulty is reflected in the literature, which lacks consensus on a treatment algorithm. The aim of this study is to propose a treatment algorithm based on patient morbidity and the efficacy of different treatment options. METHODS: The medical records of 127 patients with neuroendocrine liver metastases were reviewed. As first-line treatment, 69 of these patients underwent radiofrequency ablation (RFA), 29 patients were treated by liver resection, and 29 underwent embolization. Clinical characteristics and surgical parameters were analyzed with the chi-square test, and cumulative survival was analyzed with the Kaplan-Meier method. All data are expressed as mean ± standard error of the mean. RESULTS: Of the 3 treatment modalities, RFA was the most commonly used initial treatment for patients with up to approximately 16 discrete lesions. Resection was used to debulk large tumors of limited number. Embolization was the first-line treatment for more extensive disease not amenable to RFA or resection. RFA provided effective cytoreduction while affording patients a shorter duration of stay and lower complication rates. On univariate analysis, the size of dominant metastases, extrahepatic disease, resection of primary tumor, and treatment modality affected survival. On multivariate analysis, sex, the size of dominant metastases, and extrahepatic disease were independent predictors of survival. CONCLUSION: To our knowledge, this study is the largest report on a multimodality approach to the treatment of neuroendocrine liver metastases yet published in the literature. Because of the patient selection criteria used in our study, a direct comparison of the treatment arms is not strictly possible. We used an initial treatment algorithm based on the presentation of the patient. Because this disease has a multifocal nature and accompanying elevated recurrence rate, careful follow-up of patients and subsequent treatments are often needed to minimize disease burden.
