PURPOSE To provide rationale for using phosphoinositide 3-kinase (PI3K) and/or mitogen-activated protein kinase (MAPK) pathway inhibitors to treat rhabdomyosarcomas, a major cause of pediatric and adolescent cancer deaths. EXPERIMENTAL DESIGN The prevalence of PI3K/MAPK pathway activation in rhabdomyosarcoma clinical samples was assessed using(More)
Aromatase inhibitors (AIs) have not been used consistently as part of the management of hormone receptor positive uterine leiomyosarcomas (ULMS). As a result, the published data regarding the efficacy of AIs in this subtype of ULMS are sparse. We performed a retrospective electronic medical record review of patients with ULMS treated with an AI, in the 1st(More)
PURPOSE To determine the feasibility of induction chemotherapy and chemo-IMRT in head and neck squamous cell cancers at risk of bilateral nodal spread (midline tumours) and to evaluate whether bilateral superficial lobe parotid-sparing IMRT can reduce the incidence of ⩾G2 subjective xerostomia. METHODS Patients with midline tumours were enrolled to a(More)
We describe a case of ovarian carcinosarcoma occurring in a 60-year-old female. The neoplasm was excised after neoadjuvant chemotherapy and contained a predominant heterologous pleomorphic rhabdomyosarcomatous component in which there were numerous multivacuolated rhabdomyoblasts that strongly mimicked lipoblasts. The clear cell variant of rhabdomyosarcoma(More)
BACKGROUND Worsening drug resistance in Plasmodium falciparum malaria is a major threat to health in tropical countries. We did a prospective study of malaria incidence and treatment in an area of highly multidrug-resistant P. falciparum malaria. METHODS We assessed incidence of P. falciparum malaria and the in-vivo responses to mefloquine treatment over(More)
BACKGROUND Rhabdomyosarcomas (RMSs) are primarily paediatric sarcomas that resemble developing skeletal muscle. Our aim was to determine the effects of microRNAs (miRNA) that have been implicated in muscle development on the clinical behaviour of RMSs. METHODS Expression levels of miR-1, miR-206, miR-133a and miR-133b were quantified by RT-PCR in 163(More)
PURPOSE To determine the safety and feasibility of combining intratumoral reovirus and radiotherapy in patients with advanced cancer and to assess viral biodistribution, reoviral replication in tumors, and antiviral immune responses. EXPERIMENTAL DESIGN Patients with measurable disease amenable to palliative radiotherapy were enrolled. In the first stage,(More)
PURPOSE This study sought to define the recommended dose of JS1/34.5-/47-/GM-CSF, an oncolytic herpes simplex type-1 virus (HSV-1) encoding human granulocyte-macrophage colony-stimulating factor (GM-CSF), for future studies in combination with chemoradiotherapy in patients with squamous cell cancer of the head and neck (SCCHN). EXPERIMENTAL DESIGN(More)
Tumor genomic instability and selective treatment pressures result in clonal disease evolution; molecular stratification for molecularly targeted drug administration requires repeated access to tumor DNA. We hypothesized that circulating plasma DNA (cpDNA) in advanced cancer patients is largely derived from tumor, has prognostic utility, and can be utilized(More)
