Watch and Wait Approach for Re-excision After Unplanned Yet Macroscopically Complete Excision of Extremity and Superficial Truncal Soft Tissue Sarcoma is Safe and Does Not Affect Metastatic Risk or Amputation Rate

Annals of Surgical Oncology - The benefits of systematic re-excision (RE) after initial unplanned excision (UE) of soft tissue sarcoma (STS) are unknown. The aim of this study was to evaluate the...     

Can radiomics improve the prediction of metastatic relapse of myxoid/round cell liposarcomas?

European Radiology - The strongest adverse prognostic factor in myxoid/round cell liposarcomas (MRC-LPS) is the presence of a round cell component above 5% within the tumor bulk. Its identification...

Prognostic impact of distinct genetic entities in pediatric diffuse glioma WHO-grade II—Report from the German/Swiss SIOP-LGG 2004 cohort

Reports on pediatric low-grade diffuse glioma WHO-grade II (DG2) suggest an impaired survival rate, but lack conclusive results for genetically defined DG2-entities. We analyzed the natural history, treatment and prognosis of DG2 and investigated which genetically defined sub-entities proved unfavorable for survival. Within the prospectively registered, population-based German/Swiss SIOP-LGG 2004 cohort 100 patients (age 0.8-17.8 years, 4% neurofibromatosis [NF1]) were diagnosed with a DG2. Following biopsy (41%) or variable extent of resection (59%), 65 patients received no adjuvant treatment. Radiologic progression or severe neurologic symptoms prompted chemotherapy (n = 18) or radiotherapy (n = 17). Multiple lines of salvage treatment were necessary for 19/35 patients. Five years event-free survival dropped to 0.44, while 5 years overall survival was 0.90 (median observation time 8.3 years). Extensive genetic profiling of 65/100 DG2 identified Histone3-K27M-mutation in 4, IDH1-mutation in 11, BRAF-V600-mutation in 12, KIAA1549-BRAF-fusions in 6 patients, while the remaining 32 tumor tissues did not show alterations of these genes. Progression to malignant glioma occurred in 12 cases of all genetically defined subgroups within a range of 0.5 to 10.8 years, except for tumors carrying KIAA1549-BRAF-fusions. Histone3-K27M-mutant tumors proved uniformly fatal within 0.6 to 2.4 years. The current LGG treatment strategy seems appropriate for all DG2-entities, with the exemption of Histone3-K27M-mutant tumors that require a HGG-related treatment strategy. Our data confirm the importance to genetically define pediatric low-grade diffuse gliomas for proper treatment decisions and risk assessment.

Epidemiology of childhood tuberculosis in Switzerland between 1996 and 2011

Approximately 9 million cases of tuberculosis (TB) are reported annually and half a million occur in children <15 years of age. Globally, TB notifications in children have been neglected for decades although childhood TB may represent a sentinel for ongoing transmission. Data included in this study were collected from the TB database of the Swiss Federal Office of Public Health, which includes culture-confirmed TB and/or cases treated with ≥3 anti-mycobacterial drugs. Data from all children <15 years of age reported between 1996 and 2011 were analyzed. A total of 320 cases of TB (166 cultures confirmed, 5 confirmed by nucleic acid amplification, 149 other than definite cases) were reported with an overall incidence rate of 1.6 per 100,000 children (range 1.2–2.2). A total of 154 (48 %) children were younger than 5 years of age and 141 (44 %) were born in Switzerland. Children below 5 years of age were more likely to be Swiss-born compared to children aged 10 to 14 years (74 % versus 26 %). When analyzing the country of origin, only 55 children (17 %) were of Swiss origin. Of all children with foreign origin, 117 (47 %) were from a country within the WHO European Region. In 288 (90 %) of all notified cases, the site of disease was the lung. Mycobacterial culture was positive in 166 cases (51.9 %) with 1.8 % multi-drug-resistance. The overall incidence of childhood TB disease reported in Switzerland remained stable over a 16-year period with a remarkable high rate of very young patients of foreign origin. Only half of the reported cases were culture confirmed, highlighting the need for better diagnostic tests in childhood TB.
