Calcified desmoplastic fibroblastoma of the foot: imaging findings

We report a case of desmoplastic fibroblastoma (DF) of the foot in a 65-year-old woman. The tumor presented as a slow-growing, painless mass located in the first intermetatarsal space of the right foot. Ultrasound showed a well-circumscribed hypoechoic lesion containing hyperechoic calcifications confirmed on standard radiographs. At magnetic resonance imaging (MRI), the mass appeared isointense to the muscles on T1-weighted (T1W) images, hyperintense on proton-density-weighted fat-saturated images, and presented scattered internal hypointense foci. Post-contrast T1W spectral presaturation with inversion recovery (SPIR) images showed heterogeneous, mostly peripheral, contrast enhancement. DF must be considered in the differential diagnosis of soft-tissue calcified tumors of the foot

Selective Internal Radiation Therapy with SIR-Spheres for the Treatment of Unresectable Colorectal Hepatic Metastases

The purpose of this study was to evaluate the effectiveness of colorectal cancer (CRC) liver metastasis radioembolization with yttrium-90 (Y90), assessing toxicity and survival rates in patients with no response to chemotherapy through our 3-year experience. From February 2005 to January 2008, we treated 41 patients affected by CRC from a cohort of selective internal radiation therapy patients treated at our institution. All patients examined showed disease progression and arrived for our observation with an abdominal CT, a body PET, and a hepatic angiography followed by gastroduodenal artery coiling previously performed by us. We excluded patients with a bilirubin level > 1.8 mg/dl and pulmonary shunt > 20% but not patients with minor extrahepatic metastases. On treatment day, under fluoroscopic guidance, we implanted a dose of Y90 microspheres calculated on the basis of liver tumoral involvement and the body surface area formula. All patients were discharged the day after treatment. We obtained, according to Response Evaluation Criteria on Solid Tumors, a complete response in 2 patients, a partial response in 17 patients, stable disease in 14 patients, and progressive disease in 8 patients. In all cases, we obtained a carcinoembryonic antigen level decrease, especially in the week 8 evaluation. Technical success rate was 98% and technical effectiveness estimated at 3 months after treatment was 80.5%. Side effects graded by Common Terminology Criteria on Adverse Events were represented by one grade 4 hepatic failure, two grade 2 gastritis, and one grade 2 cholecystitis. The median survival and the progression-free survival calculated by Kaplan-Meier analysis were 354 and 279 days, respectively. In conclusion, according to our 3-year experience, Y90 SIR-Spheres radioembolization is a feasible and safe method to treat CRC liver metastases, with an acceptable level of complications and a good response rate

Survival after Yttrium-90 resin microsphere radioembolization of hepatocellular carcinoma across Barcelona clinic liver cancer stages: A European evaluation

A multicenter analysis was conducted to evaluate the main prognostic factors driving survival after radioembolization using yttrium-90-labeled resin microspheres in patients with hepatocellular carcinoma at eight European centers. In total, 325 patients received a median activity of 1.6 GBq between September 2003 and December 2009, predominantly as whole-liver (45.2%) or right-lobe (38.5%) infusions. Typically, patients were Child-Pugh class A (82.5%), had underlying cirrhosis (78.5%), and had good Eastern Cooperative Oncology Group (ECOG) performance status (ECOG 0-1; 87.7%), but many had multinodular disease (75.9%) invading both lobes (53.1%) and/or portal vein occlusion (13.5% branch; 9.8% main). Over half had advanced Barcelona Clinic Liver Cancer (BCLC) staging (BCLC C, 56.3%) and one-quarter had intermediate staging (BCLC B, 26.8%). The median overall survival was 12.8 months (95% confidence interval, 10.9-15.7), which varied significantly by disease stage (BCLC A, 24.4 months [95% CI, 18.6-38.1 months]; BCLC B, 16.9 months [95% CI, 12.8-22.8 months]; BCLC C, 10.0 months [95% CI, 7.7-10.9 months]). Consistent with this finding, survival varied significantly by ECOG status, hepatic function (Child-Pugh class, ascites, and baseline total bilirubin), tumor burden (number of nodules, alpha-fetoprotein), and presence of extrahepatic disease. When considered within the framework of BCLC staging, variables reflecting tumor burden and liver function provided additional prognostic information. The most significant independent prognostic factors for survival upon multivariate analysis were ECOG status, tumor burden (nodules >5), international normalized ratio >1.2, and extrahepatic disease. Common adverse events were: fatigue, nausea/vomiting, and abdominal pain. Grade 3 or higher increases in bilirubin were reported in 5.8% of patients. All-cause mortality was 0.6% and 6.8% at 30 and 90 days, respectively. Conclusion: This analysis provides robust evidence of the survival achieved with radioembolization, including those with advanced disease and few treatment options. \ua9 2011 American Association for the Study of Liver Diseases

RADIOEMBOLISATION IN PATIENTS WITH HEPATOCELLULAR CARCINOMA THAT HAVE PREVIOUSLY RECEIVED LIVER-DIRECT THERAPIES

Purpose: Radioembolisation is part of the multimodal treatment of hepatocellular carcinoma (HCC) at specialist liver centres. This study analysed the impact of prior treatment on tolerability and survival following radioembolisation. Methods: This was a retrospective analysis of 325 consecutive patients with a confirmed diagnosis of HCC, who received radioembolisation with yttrium-90 resin microspheres at eight European centres between September 2003 and December 2009. The decision to treat was based on the clinical judgement of multidisciplinary teams. Patients were followed from the date of radioembolisation to last contact or death and the nature and severity of all adverse events (AEs) recorded from medical records. Results: Most radioembolisation candidates were Child-Pugh class A (82.5%) with multinodular HCC (75.9%) invading both lobes (53.1%); 56.3% were advanced stage. Radioembolisation was used first-line in 57.5% of patients and second-line in 34.2%. Common prior procedures were transarterial (chemo)embolisation therapies (27.1%), surgical resection/transplantation (17.2%) and ablation (8.6%). There was no difference in AE incidence and severity between prior treatment subgroups. Median (95% confidence interval [CI]) survival following radioembolisation was similar between procedure-naive and prior treatment groups for Barcelona Clinic Liver Cancer (BCLC) stage A: 22.1\ua0months (15.1\u201345.9) versus 30.9\ua0months (19.6\u201346.8); p =\ua00.243); stage B: 18.4\ua0months (11.2\u201319.4) versus 22.8\ua0months (10.9\u201334.2); p =\ua00.815; and stage C: 8.8\ua0months (7.1\u201310.8) versus 10.8\ua0months (7.7\u201312.6); p =\ua00.976. Conclusions: Radioembolisation is a valuable treatment option for patients who relapse following surgical, ablative or vascular procedures and remain suitable candidates for this treatment
