Monitoring and Managing Lorlatinib Adverse Events in the Portuguese Clinical Setting: A Position Paper.

Rearrangements in the anaplastic lymphoma kinase (ALK) and proto-oncogene tyrosine-protein kinase ROS (ROS1) genes characterise two distinct molecular subsets of non-small cell lung cancer (NSCLC) tumours. Lorlatinib is a third-generation ALK/ROS1 tyrosine kinase inhibitor (TKI) shown to have systemic and intracranial activity in treatment-naive patients and in those who progressed on first- and second-generation TKIs. Despite being generally well tolerated, lorlatinib has a unique and challenging safety profile that includes hyperlipidaemia and central and peripheral nervous system adverse events (AEs).

Clinical insights gained by refining the 2016 WHO classification of diffuse gliomas with: EGFR amplification, TERT mutations, PTEN deletion and MGMT methylation.

Background: Significant advances in the molecular profiling of gliomas, led the 2016 World Health Organization (WHO) Classification to include, for the first-time, molecular biomarkers in glioma diagnosis: IDH mutations and 1p/19q codeletion. Here, we evaluated the effect of this new classification in the stratification of gliomas previously diagnosed according to 2007 WHO classification. Then, we also analyzed the impact of TERT promoter mutations, PTEN deletion, EGFR amplification and MGMT promoter methylation in diagnosis, prognosis and response to therapy in glioma molecular subgroup.

Impact of Radiation Target Volume on Health-Related Quality of Life in Patients With Low-Grade Glioma in the 2-Year Period Post Treatment: A Secondary Analysis of the EORTC 22033-26033.

Purpose: It is currently unknown whether increasing radiation therapy (RT) volume has a negative impact on the health-related quality of life (HRQoL) of patients with low-grade glioma in the short term. The aim was to examine whether the size of the target volume is independently associated with HRQoL.

Methods And Materials: We included patients who were treated with radiation therapy in the European Organisation for Research and Treatment of Cancer (EORTC) 22033-26033 study and who completed baseline HRQoL assessment.

Temozolomide chemotherapy versus radiotherapy in high-risk low-grade glioma (EORTC 22033-26033): a randomised, open-label, phase 3 intergroup study.

Background: Outcome of low-grade glioma (WHO grade II) is highly variable, reflecting molecular heterogeneity of the disease. We compared two different, single-modality treatment strategies of standard radiotherapy versus primary temozolomide chemotherapy in patients with low-grade glioma, and assessed progression-free survival outcomes and identified predictive molecular factors.

Methods: For this randomised, open-label, phase 3 intergroup study (EORTC 22033-26033), undertaken in 78 clinical centres in 19 countries, we included patients aged 18 years or older who had a low-grade (WHO grade II) glioma (astrocytoma, oligoastrocytoma, or oligodendroglioma) with at least one high-risk feature (aged >40 years, progressive disease, tumour size >5 cm, tumour crossing the midline, or neurological symptoms), and without known HIV infection, chronic hepatitis B or C virus infection, or any condition that could interfere with oral drug administration.

Comparison of four verbal memory tests for the diagnosis and predictive value of mild cognitive impairment.

Background: Mild cognitive impairment (MCI) is considered to be an early stage of a neurodegenerative disorder, particularly Alzheimer's disease, and the clinical diagnosis requires the objective demonstration of cognitive deficits. The aim of the present study was to evaluate the predictive value of MCI for the conversion to dementia when using four different verbal memory tests (Logical Memory, LM; California Verbal Learning Test, CVLT; Verbal Paired-Associate Learning, VPAL; and Digit Span, DS) in the MCI criteria.

Methods: Participants were consecutive patients with subjective cognitive complaints who performed a comprehensive neuropsychological evaluation and were not demented, observed in a memory clinic setting.

Mixed testicular germ cell tumour in a patient with previous pineal germinoma.

Germ cell tumours (GCT) are a relatively common malignancy in men aged 15-35 years. They occur most frequently in the gonads, but 3-5% have extragonadal origin, mainly in the pineal gland, neurohypophysis, mediastinum and retroperitoneum. Although intracranial germinomas may present with synchronous midline lesions, development of metachronous testicular germ cell primaries seems to be extremely rare, and confirmed dissemination of intracranial GCT to the testes has never been reported.
