Incidence of oropharyngeal tumors has risen in both nH black and white males. However, nH white males have higher incidence of HPV, and nH black males have higher incidence of more aggressive and advanced HNSCCs. Racial differences in clinical characteristics associated with poorer survival exist, and future studies should determine factors associated with these differences.
Lung cancer is the leading cause of cancer-related deaths worldwide. Approximately 85% of all lung cancers are non-small cell histology [non-small cell lung cancer (NSCLC)]. Modern treatment strategies for NSCLC target driver oncogenes and immune checkpoints. However, less than 15% of patients survive beyond 5 years. Here, we investigated the effects of SAR302503 (SAR), a selective JAK2 inhibitor, on NSCLC cell lines and tumors. We show that SAR is cytotoxic to NSCLC cells, which exhibit resistance to genotoxic therapies, such as ionizing radiation, cisplatin, and etoposide. We demonstrate that constitutive IFN-stimulated gene expression, including an IFN-related DNA damage resistance signature, predicts for sensitivity to SAR. Importantly, tumor cell-intrinsic expression of PD-L1 is IFN-inducible and abrogated by SAR. Taken together, these findings suggest potential dual roles for JAK2 inhibitors, both as a novel monotherapy in NSCLCs resistant to genotoxic therapies, and in tandem with immune checkpoint inhibition. .
American Society of Clinical Oncology Annual Meeting, Chicago, IL, USA, 3-7 June 2016 The American Society of Clinical Oncology Annual Meeting took place in Chicago, IL, USA, from 3 to 7 June 2016. Over 30,000 oncologists, researchers, related professionals and advocates participated in the conference, which covered all aspects of oncology. An overview of the key studies in brain metastases presented at the 2016 American Society of Clinical Oncology Annual Meeting is highlighted here. Key data presented on radiotherapy, and systemic therapy for brain metastases are reviewed.
Conventional external beam radiotherapy has been historically employed in the treatment of pituitary adenomas either as a single modality or following suboptimal surgical resection. However, with the widespread adoption of the trans-sphenoidal surgery, the role of radiation therapy has been limited to cases deemed resectable or in those with subtotal resections. Advances in radiotherapy have improved the dose distribution to the pituitary mass while minimizing the volume of normal tissues receiving doses of radiation near or exceeding their inherent tolerances, permitting radiation oncologists to migrate from simple 2D radiation planning to 3D planning. Fractionated radiosurgery, linear-accelerator/gamma source-based radiosurgery, or image-guided/intensity-modulated radiotherapy is now commonly employed. Long-term follow-up data demonstrate excellent progression-free survival and local control along with few complications for all radiation treatment modalities whether employed as monotherapy or following subtotal resection.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
