A Phase 2 Study of the Hsp90 Inhibitor AUY922 as Treatment for Patients with Refractory Gastrointestinal Stromal Tumors.

Background: AUY922 is an inhibitor of heat shock protein 90 (Hsp90). Hsp90 inhibitors induce kit degradation in preclinical gastrointestinal stromal tumor (GIST) models. This trial was designed to determine the progression-free survival (PFS) of patients with GIST refractory to or intolerant of imatinib and sunitinib.

Panitumumab, Gemcitabine, and Carboplatin as Treatment for Women With Metastatic Triple-Negative Breast Cancer: A Sarah Cannon Research Institute Phase II Trial.

Background: Triple-negative breast cancer (TNBC) is a subtype with poor prognosis, and treatment options are limited to chemotherapy. Because the epidermal growth factor receptor (EGFR) is overexpressed in up to 70% of these tumors, this phase II trial was designed to evaluate the efficacy and safety of panitumumab in combination with gemcitabine and carboplatin as first- or second-line treatment for metastatic TNBC.

Patients And Methods: Adult women with metastatic TNBC with a maximum of 1 previous chemotherapy regimen were eligible.

Concurrent radiotherapy and temozolomide followed by temozolomide and sorafenib in the first-line treatment of patients with glioblastoma multiforme.

Background: The current study was conducted to evaluate the efficacy of sorafenib, an oral vascular endothelial growth factor receptor tyrosine kinase inhibitor, when added to standard radiotherapy and temozolomide in the first-line treatment of patients with glioblastoma multiforme.

Methods: After initial surgical resection or biopsy, patients with newly diagnosed glioblastoma multiforme received concurrent radiotherapy (2.0 grays [Gy]/day; total dose, 60 Gy) and temozolomide (at a dose of 75 mg/m2 orally daily), followed by 6 months of maintenance therapy with temozolomide (at a dose of 150 mg/m2 orally on Days 1-5 every 28 days) and sorafenib (at a dose of 400 mg orally twice daily).

Unsuspected skeletal sarcoidosis mimicking metastatic disease on FDG positron emission tomography and bone scintigraphy.

Sarcoidosis is a disease process of unknown cause that exhibits heterogeneous clinical manifestations. Although the mediastinum and lungs are most commonly involved, the granulomatous process may also affect the skeleton, skin, eyes, kidneys, spleen, and liver. A 51-year-old woman with low back pain and no history of cancer was found to have a suspicious lesion at L4 on magnetic resonance imaging.
