RESEARCH REPORT Leah Lawrence Limited surgical resection of duodenal gastrointestinal stromal tumors resulted in positive outcomes for both local and systemic disease-free survival, according to the results of a small study.
RESEARCH REPORT Leah Lawrence A majority of patients on imatinib for treatment of GIST or CML had low or absent levels of osteocalcin, a bone marker secreted by osteoblasts, and about 50% of patients had a decrease in bone mineral density, signaling that long-term treatment may affect bone health in these patients.
TEST YOUR IMAGE IQ Robert D. Cardiff, MD, PhD A 58-year-old male presents with chief complaints of bloating, vague abdominal pain, and dark black stools. He is referred to a gastroenterologist who recommends upper and lower endoscopy. What is the most likely diagnosis?
REVIEW ARTICLEONCOLOGY Vol. 26 No. 10 We describe areas where major inroads were initially achieved by targeting angiogenesis and by unraveling pathways in the heterogeneous tumors of mesenchymal origin—spurred by the identification of c-Kit–activating mutations in GIST and the regressions that ensued when tumors harboring these mutations were exposed to the tyrosine kinase inhibitor imatinib (Gleevec).
REVIEW ARTICLEONCOLOGY Vol. 23 No. 1 This review describes the current multidisciplinary management of gastrointestinal stromal tumor (GIST), which is the most common sarcoma of the gastrointestinal tract. Before 2001, surgery was the only effective therapy for GIST.

• Improving Harmonious Precision • Targeted Therapy for Cancer: Asking the Right Questions
The impact of neoadjuvant drug therapy needs to be further classified and explored. With additional evaluation of other tyrosine kinase inhibitors and novel therapies against other molecular markers, the treatment paradigm for this malignancy should continue to evolve.
• Treatment of GIST: Clarifying the Data
We report a case of a patient who developed Guillain-Barré syndrome after initial treatment with sunitinib, with recurrent symptoms upon reintroducing the drug. This is the first report of such an effect.
• Is Guillain Barré Syndrome Likely in This Patient?
The molecular and genomic determinants of response/resistance patterns are the subject of ongoing studies, and adjuvant studies are also under way. The initial evaluations of imatinib provide proof of concept for the hypothesis-driven design of selective molecularly targeted therapies for solid tumor malignancies.

Primary Care Can't Thrive Without Nurse Practitioners Courtney H. Lyder, ND, May 17, 2013 With a projected shortfall of primary-care physicians, it's time for alternate solutions to patient care. Nurse practitioners are one logical remedy.
