Despite neoadjuvant chemotherapy and wide surgical ablation, 15% to 25% of patients with primary osteosarcoma will relapse (local recurrence or metastases). Neither chemotherapy nor radiation therapy alone will render a patient disease-free without concomitant surgical ablation of relapse. We prefer excision of relapse when possible. However, it is unclear whether ...

Treatment of soft tissue sarcoma (STS) includes complete tumor excision. However, in some patients, residual sarcoma cells remain in the tumor bed. We previously described a novel hand-held imaging device prototype that uses molecular imaging to detect microscopic residual cancer in mice during surgery. To test this device in a ...

The 5-year survival rates for localized liposarcomas reportedly vary from 75% to 91% with histologic grade as the most important prognostic factor. However, it is unclear which other factors, including the initial surgery quality and recurrent tumors, influence survival in localized liposarcomas (LPS). We analyzed factors (including AJCC staging system) ...

The literature on osteosarcoma survival generally focuses on tumor and treatment variables, although it is unclear whether and how ethnic and socioeconomic factors might influence survival. We therefore investigated the relative contribution of socioeconomic influences together with more traditional tumor-specific factors on osteosarcoma survival. We performed survival analyses on two ...

Ybt1p is a class C ABC transporter (ATP-binding cassette transporter) that is localized to the vacuole of Saccharomyces cerevisiae. Although Ybt1p was originally identified as a bile acid transporter, it has also been found to function in other capacities, including the translocation of phosphatidylcholine to the vacuole lumen, and the ...

Translocation of gastrointestinal bacteria in HIV-infected individuals is associated with systemic inflammation, HIV progression, mortality, and comorbidities.
