Previous studies have shown that total epidermal growth factor receptor (EGFR) protein is highly expressed in soft tissue sarcoma (STS). We aimed to investigate the significance of phosphorylated-EGFR (pEGFR) and its activated-downstream signal transducers in STS tissue samples. A tissue microarray comprising 87 STS samples was assessed for total EGFR, pEGFR and its phosphorylated signal transducers and expression was correlated with clinicopathlogical parameters including patient outcome. Although the expression of total EGFR was significantly associated with adverse STS histologic grade (p = 0.004) and clinical stage (p = 0.012) similar to pEGFR, phosphorylated protein kinase B (pAkt) and phosphorylated extracellular signal regulated kinase (pERK), it is not a prognostic factor for survival. By contrast, the expression of pEGFR is an independent factor for cancer specific survival, while pERK is an independent prognostic factor for both overall and cancer specific survival in STS (p < 0.05, Cox proportional hazard model and log-rank test) in addition to the recognised factors of tumour grade and clinical stage. pERK and pEGFR are new independent prognostic factors for overall and/or cancer specific survival in STS. The expression of EGFR/pEGFR, and their associated downstream signal transducers, was associated with STS progression, suggesting that EGFR downstream signalling pathways may jointly support STS cell survival.

Necrotising fasciitis (NF) is a fulminant and life-threatening soft tissue infection, which leads to vascular thrombosis and cutaneous ischemia. We present our experience with extensive necrotising fasciitis in a 4-day-old neonate and stress the importance of early diagnosis, modern dressings including negative pressure therapy, prompt surgical debridement and intensive care to improve the survival and cosmetic outcome of children with NF.

We propose that this regimen represents a novel therapy for management of ulcerated infantile haemangioma. Possible mechanisms for healing effect, and improved analgesia are discussed. Further investigation is required to determine if negative pressure wound therapy results in faster healing times compared to traditional dressing regimens.
