- Purpose: To investigate the outcome following adjuvant doxorubicin and ifosfamide in a prospective non-randomised study based on a soft tissue sarcoma (STS) patient subgroup defined by specific morphological characteristics previously shown to be at a high-risk of metastatic relapse. The expected 5-year cumulative incidence of metastases in patients with this risk profile has previously been reported to be about 50% without adjuvant chemotherapy.Methods: High-risk STS was defined as high-grade morphology (according to the Federation Nationale des Centres de Lutte Contre le Cancer [FNCLCC] grade II-III) and either vascular invasion or at least two of the following criteria: tumour size >= 8.0 cm, infiltrative growth and necrosis. Six cycles of doxorubicin (60 mg/m(2)) and ifosfamide (6 g/m(2)) were given. Postoperative accelerated radiotherapy was applied and scheduled between cycles 3 and 4.Results: For the 150 eligible patients, median follow-up time for metastases-free survival was 3.9 years (range 0.2-8.7). Five-year metastases-free survival (MFS) was 70.4% (95% confidence interval [CI]: 63.1-78.4) with a local recurrence rate of 14.0% (95% CI: 7.8-20.2). For overall survival (OS), the median follow-up time was 4.4 years (range: 0.2-8.7). The five-year OS was 76.1% (95% CI: 68.8-84.2). Tumour size, deep location and reduced dose intensity (<80%) had a negative impact on survival. Toxicity was moderate with no treatment-related death.Conclusions: A benefit of adjuvant chemotherapy, compared to similar historical control groups, was demonstrated in STS patients with defined poor prognostic factors. Vascular invasion, tumour size, growth pattern and necrosis may identify patients in need of adjuvant chemotherapy.

- A total of 15 SNPs within complement genes and present on the ImmunoChip were analyzed in The Environmental Determinants of Diabetes in the Young (TEDDY) study. A total of 5474 subjects were followed from three months of age until islet autoimmunity (IA: n = 413) and the subsequent onset of type 1 diabetes (n = 115) for a median of 73 months (IQR 54-91). Three SNPs within ITGAM were nominally associated (p < 0.05) with IA: rs1143678 [Hazard ratio; HR 0.80; 95% CI 0.66-0.98; p = 0.032], rs1143683 [HR 0.80; 95% CI 0.65-0.98; p = 0.030] and rs4597342 [HR 1.16; 95% CI 1.01-1.32; p = 0.041]. When type 1 diabetes was the outcome, in DR3/4 subjects, there was nominal significance for two SNPs: rs17615 in CD21 [HR 1.52; 95% CI 1.05-2.20; p = 0.025] and rs4844573 in C4BPA [HR 0.63; 95% CI 0.43-0.92; p = 0.017]. Among DR4/4 subjects, rs2230199 in C3 was significantly associated [HR 3.20; 95% CI 1.75-5.85; p = 0.0002, uncorrected] a significance that withstood Bonferroni correction since it was less than 0.000833 (0.05/60) in the HLA-specific analyses. SNPs within the complement genes may contribute to IA, the first step to type 1 diabetes, with at least one SNP in C3 significantly associated with clinically diagnosed type 1 diabetes.
