RESUMEN

In a 72-year-old patient with anemia (Hb 7 g/dl), duodenoscopy exhibited an area of polypous irregular-looking mucosa. Histology revealed duodenal infiltration by epithelioid tumor cells, immunhistochemically positive for endothelial cell markers (CD34, CD31, ERG). Ultrasonography showed thrombotic material in the otherwise unremarkable abdominal aorta with some uptake of contrast bubbles on CEUS. Histological and clinical diagnosis assumed an epithelioid angiosarcoma of the thoraco-abdominal aorta at the level of the visceral and renal arteries with duodenal metastases.To prevent further shedding of tumor cells and aortic rupture, a branched stent-graft was placed into the thoraco-abdominal aorta. Palliative chemotherapy with gemcitabine and docetaxel was started, leading to a partial remission after 6 cycles. Three months later, however, there was a progress of the duodenal masses with new pulmonal and osseous metastases. Thirteen months after the initial diagnosis, death occured due to a hemorrhagic shock caused by a hematothorax.Aortic tumors are exceedingly rare, with only slightly more than 220 cases reported so far. In most cases, diagnosis is made either at autopsy or after an emergency operation for embolic complications like embolic intestinal ischemia. With an overall median survival of 8 months, prognosis is very poor.This case sensitizes for the correct sonographic interpretation of aortic "thrombi" in an otherwise normally appearing aorta, possibly with the aid of CEUS. Besides, it demonstrates the relatively early and uncommon diagnosis of an aortic angiosarcoma by the combination of endoscopy, immunohistochemistry, and ultrasonography.

RESUMEN

In patients with relapsed or refractory (r/r) acute myeloid leukemia (AML), allogeneic hematopoietic stem cell transplantation (HSCT) is considered to be the only treatment providing long-term disease control. The BRIDGE trial studied the safety and efficacy of a clofarabine-based salvage therapy before HSCT in patients with r/r AML. Here, we report the long-term follow-up of this phase II multicenter trial and exploratory analyses on the impact of comorbidity on outcome. Eighty-four patients with a median age of 61 years (range, 40 to 75) were enrolled. Patients were scheduled for at least 1 cycle of salvage therapy with CLARA (clofarabine 30 mg/m2; cytarabine 1 g/m2, days 1 to 5). Chemo-responsive patients with a donor received HSCT after first CLARA. The conditioning regimen consisted of clofarabine 30 mg/m2, day -6 to -3, and melphalan 140 mg/m2 day -2. The Eastern Cooperative Oncology Group (ECOG) score, the hematopoietic cell transplantation-specific comorbidity index (HCT-CI), and the Cumulative Illness Rating Scale were obtained at study enrollment as well as before HSCT. Sixty-seven percent of the patients received HSCT within the trial. After a median follow up of 40 months, the estimated 3-year overall survival (OS) for all enrolled patients and those with HSCT within the trial was 40% and 55%, respectively. Relapse-free survival for patients who underwent transplantation with a complete remission afterwards (n = 50) was 48%, calculated from the day of transplantation. In multivariate analysis, both the HCT-CI and ECOG score had a statistically significant impact on OS with a hazard ratio of 1.22 (P = .025)and 1.72 (P = .001), respectively. Using a clofarabine-based salvage therapy combined with early allogeneic HSCT, we were able to achieve good long-term results for patients with r/r AML. In this cohort, both the HCT-CI and the ECOG scores gave prognostic information on OS, showing the feasibility and clinical relevance of comorbidity evaluation at the time of diagnosis of r/r AML patients.

RESUMEN

BACKGROUND: Alveolar soft-part sarcoma (ASPS) is a rare sarcoma often occurring in young patients that is characterized by the unbalanced translocation der(17)t(X;17) (p11;q25). Although it usually shows an indolent clinical course, the prognosis is usually poor in advanced disease. Since standard chemotherapy regimens used in soft-tissue sarcomas lack efficacy in ASPS, new therapeutic options are needed. We investigated the efficacy of trabectedin, which has demonstrated activity in a variety of cancer types including some of the most prevalent translocation-related sarcomas. PATIENTS AND METHODS: 7 patients with metastatic or advanced ASPS treated with trabectedin in the Sarcoma Center Berlin-Brandenburg and the University Hospital of Greifswald were analyzed for median progression-free survival (mPFS), overall survival (OS), and therapy-related toxicity. RESULTS: In 6 patients with documented disease progression, disease stabilization was reached with trabectedin; only 1 patient experienced progressive disease. The mPFS and OS were 7 months and 21 months, respectively, since the start of trabectedin treatment. Overall, no severe Common Toxicity Criteria (CTC) grade 3 or 4 toxicity was observed. CONCLUSIONS: The poor prognosis of patients with ASPS has so far been due to the unavailability of effective systemic treatments. Trabectedin can be considered the only currently registered drug with clinical activity in this disease.

RESUMEN

Deficits in processing of auditory stimuli are known to play an important role in the aetiology of dyslexia. To specify the auditory deficit in children at risk for dyslexia, 19 children with a phonological deficit and 15 controls were tested using the mismatch negativity event-related potential, which reflects preattentive auditory processing. Children with a phonological deficit, not yet suffering from dyslexia, had similar mismatch negativity patterns to dyslexics. The deficit was speech specific, because there were significant group differences only with syllables but not with pure tones.
