Background and Purpose-Strokes have especially devastating implications if they occur early in life; however, only limited information exists on the characteristics of acute cerebrovascular disease in young adults. Although risk factors and manifestation of atherosclerosis are commonly associated with stroke in the elderly, recent data suggests different causes for stroke in the young. We initiated the prospective, multinational European study Stroke in Young Fabry Patients (sifap) to characterize a cohort of young stroke patients. Methods-Overall, 5023 patients aged 18 to 55 years with the diagnosis of ischemic stroke (3396) *Drs Rolfs, Fazekas and Grittner contributed equally to this work. Authors contributions: Dr Rolfs has conceptualized, initiated, and designed and organized the study, has been involved in the recruitment of the patients, and wrote significant parts of the manuscript.

Gemcitabine sensitizes tumor cells to radiation and cisplatin and thereby enhances the cytotoxic effect of gemcitabine. Here we report the efficacy and toxicity of concurrent chemoradiation with gemcitabine and cisplatin in the treatment of patients with locally advanced, unresectable pancreatic cancer. A total of 47 patients (29 men, 18 women; median age 61 years) with histologically proven advanced pancreatic carcinoma were included in the study. They underwent chemotherapy with gemcitabine 300 mg/m2 and cisplatin 30 mg/m2 on days 1, 8, 22, and 29; concurrent radiation (45-50 Gy) was applied to the tumor and regional lymph nodes (1.8-2.0 Gy/fraction 5 days per week). Subsequent to chemoradiotherapy, treatment was continued with more two cycles of gemcitabine (1000 mg/m2) and cisplatin (50 mg/m2) applied on days 1 and 15 of a 4-week cycle. After completion of chemoradiotherapy, 9 patients (19.1%) achieved a complete response and 23 patients (48.9%) a partial response, for an overall response rate of 68%. The lesions were considered resectable in 27 patients, and 25 of the 27 patients underwent laparotomy. The other 20 patients underwent a definitive pancreatic resection. Altogether, 13 patients had negative surgical margins. With a median follow-up of 25.7 months (range 12.7-38.7 months) after completion of chemoradiation, distant metastasis had occurred in 23 patients and local recurrence in only 4 of 44 patients (8.5%). the median progression-free survival was 7.8 months (range 6.2-9.4 months). The median survival amounted to 10.7 months (range 8.4-13.0 months) for all patients, whereas it was prolonged to 24.2 months (range 6.8-41.7 months) for those undergoing R0 resection. The main toxicities associated with chemoradiation included grade 3/4 leukopenia (68% of patients) and thrombocytopenia (61%). Episodes of cholangitis were observed in 11 patients. We concluded that gemcitabine and cisplatin can safely be combined with external beam radiation. This preoperative treatment approach is highly effective and appears to improve survival in patients whose tumors are rendered completely resectable.

Microvessel density (MVD) and blood and lymphatic vessel invasion (BLVI) were investigated with regard to their influence on the disease-free survival (DFS) in node-negative breast cancer patients. Paraffin embedded microsections of 230 patients with T1,2 N0 breast cancer were immunohistochemically stained for factor VIII-related antigen. Every cluster consisting of more than highlighted endothelial cells was considered a countable microvessel. MVD was counted in 4 fields of 0.25 mm2 each. All MVD values are given as value for the sum of 4 fields of 0.25 mm2 each, that is, I mm2. BLVI was considered positive, when at least one tumor cell could be identified in a stained lumen. Out of 230 patients, 49 experienced local or distant recurrence and had a mean MVD of 72.4/mm2, whereas 181 patients who lived without recurrent disease had a mean MVD of 45.3/mm2. BLVI was negative in 6.2% of the cases with and in 93.8% of the cases without recurrent disease. BLVI was positive in 59.4% of the cases without and 40.6% of the cases with recurrent disease. MVD and BLVI remained the only significant prognostic factors of DFS in the Cox-Model. Tumor size, histological grade, and hormonal-receptor status were not prognostically relevant in the Cox-model. 10-year-DFS was 93.3% in BLVI-negative/MVD < or = 40/mm2 patients, 88.1% when MVD was high or BLVI was positive and 48.9% in BLVI positive/MVD < or = 40/mm2 patients. Our present data indicate that MVD and BLVI identify a very-low risk group among node-negative breast cancer patients, who will not benefit from systemic adjuvant therapy. MVD and BLVI should be used as stratification criteria in clinical trails on node-negative breast cancer patients.

Our data revealed a 7.9% incidence of radiographically evident unilateral pulmonary oedema after MICS with intraoperative collapse of a lung. Of the total number of patients, 1.5% simultaneously developed clinical symptoms. The influence of corticosteroids, as well as the contribution of possible risk factors, needs further evaluation.
