We have evaluated the feasibility, toxicity, and tumour response of concurrent whole-brain radiotherapy (WBRT) and chemotherapy with cisplatin, vindesine and mitomycin in the treatment of 33 patients with brain metastasis from non-small-cell lung cancer (NSCLC). The imaging response demonstrated that 25 patients (75.8%) responded to brain lesions, including five complete responders, and the response rate to primary lesion was 18%. The treatment improved at least one grade of performance status in 30% and of neurological functions in 55% of the patients. The major toxicity was leucopenia (> or = grade 3, 84.4%). Median survival was 9.7 months and the 1-year survival rate was 40%. Concurrent WBRT and chemotherapy can be safely administered to patients with brain metastasis from NSCLC, with a remarkable response rate, improvement of neurological functions and encouraging survival duration.

Cyclin-dependent kinase 5 (CDK5), a unique member of the CDK family, is a proline-directed serine/threonine protein kinase with critical roles in various physiological and pathological processes. Widely expressed in the central nervous system, CDK5 is strongly implicated in neurological diseases. Beyond its neurological roles, CDK5 is involved in metabolic disorders, psychiatric conditions, and tumor progression, contributing to processes such as proliferation, migration, immune evasion, genomic stability, and angiogenesis.

Mutations in Sonic Hedgehog (SHH) signaling pathway genes, for example, (SUFU), drive granule neuron precursors (GNP) to form medulloblastomas (MB). However, how different molecular lesions in the Shh pathway drive transformation is frequently unclear, and mutations in the cerebellum seem distinct. In this study, we show that fibroblast growth factor 5 (FGF5) signaling is integral for many infantile MB cases and that expression is uniquely upregulated in infantile MB tumors.

Lung cancer is a malignant tumor with high morbidity and mortality in China and worldwide. Once it metastasizes to the brain, its prognosis is very poor. Brain metastases are found in about 20% of newly diagnosed non-small-cell lung cancer (NSCLC) patients.

Objective: To develop a machine learning-based clinical and/or radiomics model for predicting the primary site of brain metastases using multiparametric magnetic resonance imaging (MRI).
Materials And Methods: A total of 202 patients (87 males, 115 females) with 439 brain metastases were retrospectively included, divided into training sets (brain metastases of lung cancer [BMLC] = 194, brain metastases of breast cancer [BMBC] = 108, brain metastases of gastrointestinal tumor [BMGiT] = 48) and test sets (BMLC = 50, BMBC = 27, BMGiT = 12). A total of 3,404 quantitative image features were obtained through semi-automatic segmentation from MRI images (T1WI, T2WI, FLAIR, and T1-CE).

Glioblastoma multiforme (GBM) is a World Health Organisation (WHO) grade IV glioma originating from astrocytes. It is the most common malignant primary tumour of the brain and central nervous system (CNS) and is associated with fast progression and violent local spread, with a median overall survival of approximately 15 months after diagnosis. Due to its late and varied presentation, it is often diagnosed only after it has grown considerably.
