Single-institution experience of intensity-modulated radiotherapy for malignant pleural mesothelioma at University of Catania.

AIM: The multimodal approach to malignant pleural mesothelioma is gradually becoming the standard of care for this disease in patients with good performance status. Materials & methods: We report our experience concerning eight cases treated with the use of static step-and-shoot intensity-modulated radiotherapy to the whole pleural cavity, in patients already undergoing surgical and/or antiblastic therapy. Results & conclusion: Results at a median follow-up of 16 months showed a median survival from the initial treatment of 29 months, with lung toxicity of grade II reported only in two patients.

Combined taxane-based chemotherapy and intensity-modulated radiotherapy with simultaneous integrated boost for gastroesophageal junction adenocarcinoma.

We describe our experience, gained over the past 3 years, in the treatment of gastroesophageal junction adenocarcinoma, whose incidence has been increasing in recent years. In our series, we present the results to a follow-up of about 2 years for a total of 18 patients, treated with a particularly intensive combination treatment. It consists of neoadjuvant induction chemotherapy with the protocol docetaxel-cisplatin-5-fluorouracil for four cycles, before a concomitant chemoradiotherapy treatment. During combined phase, patients received an intensity-modulated radiotherapy and a weekly cisplatin. We will present the data to a long follow-up time and we will discuss the literature, the integration with thoracoabdominal surgery and other specific issues of this pathology.

Follicular dendritic cell sarcoma of mediastinum: a key role of radiotherapy in a multidisciplinary approach.

Follicular dendritic cell sarcoma is a rare and aggressive tumor and its management is a major clinical challenge. Surgery is considered the mainstay of treatment and no adjuvant approach has demonstrated the ability to reduce the rate of relapses. We report on a case of a man with a 26-year clinical history of mediastinal follicular dendritic cell sarcoma, with several relapses after multiple surgical interventions. The impact of chemotherapy was very small, unlike the radiation therapy that was performed twice, with an interval time of 8 years, through an intensity-modulated technique and an altered fractionation schedule.

Time Course of Ischemic and Bleeding Burden in Elderly Patients With Acute Coronary Syndromes Randomized to Low-Dose Prasugrel or Clopidogrel.

Background Elderly patients have high ischemic and bleeding rates after acute coronary syndrome; however, the occurrence of these complications over time has never been studied. This study sought to characterize average daily ischemic rates ( ADIRs ) and average daily bleeding rates ( ADBRs ) over 1 year in patients aged >74 years with acute coronary syndrome undergoing percutaneous coronary intervention who were randomized in the Elderly ACS 2 trial, comparing low-dose prasugrel (5 mg daily) with clopidogrel (75 mg daily). Methods and Results ADIRs and ADBRs were calculated as the total number of events, including recurrent events, divided by the number of patient-days of follow-up and assessed within different clinical phases: acute (0-3 days), subacute (4-30 days), and late (31-365 days). Generalized estimating equations were used to test the least squares mean differences for the pairwise comparisons of ADIRs and ADBRs and the pairwise comparison of clopidogrel versus prasugrel effects. Globally, ADIRs were 2.6 times (95% CI, 2.4-2.9) higher than ADBRs . ADIRs were significantly higher in the clopidogrel arm than in the low-dose prasugrel arm in the subacute phase ( Padj<0.001) without a difference in ADBRs ( Padj=0.35). In the late phase, ADIRs remained significantly higher with clopidogrel ( Padj<0.001), whereas ADBRs were significantly higher with low-dose prasugrel ( Padj<0.001). Conclusions Ischemic burden was greater than bleeding burden in all clinical phases of 1-year follow-up of elderly patients with acute coronary syndrome treated with percutaneous coronary intervention. Low-dose prasugrel reduced ischemic events in the subacute and chronic phases compared with clopidogrel, whereas bleeding burden was lower with clopidogrel in the late phase.

Effects of α-lipoic acid therapy on sympathetic heart innervation in patients with previous experience of transient takotsubo cardiomyopathy.

BACKGROUND: Takotsubo syndrome is a stress cardiomyopathy, characterized by reversible left ventricle (LV) apical ballooning in the absence of significant angiographic coronary artery stenosis. The frequent association with emotional stress suggests in this disease an autonomic nervous system involvement. We could think that a therapeutic treatment targeting heart sympathetic dysfunction could be of crucial importance. METHODS: From January 2010 to June 2012, 886 patients were consecutively evaluated at Cardarelli Hospital, Naples, Italy. Among these, 48 patients met takotsubo cardiomyopathy (TCM) criteria. Each patient was assessed with history and physical examination, 12-lead electrocardiogram, serum troponin, coronary arteriography, and left ventricular angiogram, perfusion myocardial scintigraphy with technetium 99m, with echocardiography and 123I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy. At discharge, the surviving patients were randomly assigned to α-lipoic acid (ALA) treatment (600mg once daily) or placebo. Following discharge, after the initial TCM event, patients returned to our outpatient clinic at Internal Medicine of the Second University Naples for the follow-up evaluation quarterly until 12 months. Routine analysis, myocardial damage serum markers, oxidative stress serum markers, pro-inflammatory cytokines, and sympathetic tone activity were evaluated in all patients. RESULTS: ALA administration improved MIBG defect size at 12 months compared to placebo. CONCLUSIONS: Adrenergic cardiac innervation dysfunction in TCM patients persists after previous experience of transient stress-induced cardiac dysfunction. ALA treatment improves the adrenergic cardiac innervation. This study evaluates whether sympatho-vagal alterations are TCM event-related.
