Severity of effect considerations regarding the use of mutation as a toxicological endpoint for risk assessment: A report from the 8th International Workshop on Genotoxicity Testing (IWGT)

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

Non-Hodgkin Lymphoma after Treatment with Extended Dosing Temozolomide and Radiotherapy for a Glioblastoma: A Case Report

Case Reports in Oncology, 2013
Temozolomide (TMZ) is an alkylating agent, used for the treatment of high-grade gliomas. This case report describes the development of a non-Hodgkin lymphoma in a patient treated with extended-dose temozolomide and radiotherapy.

Conditional survival in glioblastoma: The evolution of prognostic factors over time

International Journal of Cancer, EarlyView.
What's New? Neurooncologists rely on glioblastoma risk stratification systems for incorporating known disease‐ and patient‐specific factors at diagnosis. Although useful for general comparison and disease monitoring, these estimates are less informative for patients who survive beyond various time intervals post‐diagnosis.

Selective regulation of chemosensitivity in glioblastoma by phosphatidylinositol 3-kinase beta

iScience
Summary: Resistance to chemotherapies such as temozolomide is a major hurdle to effectively treat therapy-resistant glioblastoma. This challenge arises from the activation of phosphatidylinositol 3-kinase (PI3K), which makes it an appealing therapeutic ...

Molecular–clinical characteristics and treatment outcomes in 163 metastatic colorectal neuroendocrine carcinomas with a comparison to colorectal adenocarcinomas

International Journal of Cancer, EarlyView.
What's New? Colorectal neuroendocrine carcinoma (CR‐NEC) is a rare digestive neuroendocrine neoplasm that frequently exhibits an adenocarcinoma component. Nonetheless, the underlying biology of CR‐NEC remains poorly understood. This study examined molecular and clinical features and palliative chemotherapy outcomes of metastatic CR‐NEC, with comparison

Progress of temozolomide in the treatment of recurrent high-grade gliomas

Chinese Journal of Contemporary Neurology and Neurosurgery, 2013
High-grade gliomas are central nervous system malignancies which are difficult to treat. Surgery, temozolomide combined with radiotherapy postoperatively and adjuvant chemotherapy with temozolomide have been established as the standard treatment options ...

RTA‐408 Enhances Radiosensitivity and Inhibited Tumor Progression via JNK Pathway in Glioblastoma

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Glioblastoma (GBM) is an aggressive brain tumor with poor prognosis owing to its high invasiveness and resistance to therapy. RTA‐408, a synthetic triterpenoid and nuclear factor erythroid 2‐related factor 2 activator, exhibits anti‐inflammatory and anti‐cancer properties; however, its effects on GBM remain unclear. This study investigated the
