Brain metastases (BC) are the cause of important mortality and morbidity in cancer patients. Corticoids and Whole Brain Radiotherapy (WBRT) remains the standard treatment but, at the long-term, the results are disappointing. In patients with a single metastase, the survival and the Quality of Life (QoL) can be improved by surgery combined with WBRT. Unfortunately, if surgery (S) is impossible because of the number and/or the site of the metastases or any contraindication for surgery, radiosurgery (RS) remains a good alternative choice. RS allows an excellent local control of the lesions and can be applied to several lesions at the same time. There is no advantage in in terms of survival between RS + WBRT and S + WBRT or RS alone. RS can therefore be recommended as a first treatment approach, namely when favourable prognostic factors are present. This approach allows to avoid WBRT and its potential toxicity, namely in long-term survival.

Background: Health-related quality of life (HRQoL) is critical for patients with lung cancer due to poor prognosis. We presented patient-reported outcomes in patients with non-small cell lung cancer (NSCLC) brain metastases (BM) who received whole-brain radiotherapy (WBRT) in combination with erlotinib or WBRT alone in the phase 3 ENTER study.
Methods: The patients' HRQoL was assessed by using the European Organization for Research and Treatment of Cancer 30-item Core Quality of Life Questionnaire (EORTC QLQ-C30).

Background: A major concern in anticancer treatment (ACT) of brain metastases (BM) is exposing patients with short expected survival to treatments that negatively impact on quality of life (QoL). Such futile ACT at the end of life is time-consuming and burdensome for patients and their families and entails unnecessary healthcare costs. Refraining from ACT is challenging for both physicians and patients.

Background: Patients with non-small cell lung cancer (NSCLC) are prone to developing brain metastases (BMs), particularly those with epidermal growth factor receptor (EGFR) mutations. In clinical practice, treatment-naïve EGFR-mutant NSCLC patients with asymptomatic BMs tend to choose EGFR-tyrosine kinase inhibitors (TKIs) as first-line therapy and defer intracranial radiotherapy (RT). However, the effectiveness of upfront intracranial RT remains unclear.

Effective therapies for cognitive impairments induced by brain irradiation are currently lacking. This study investigated the therapeutic potential of hyperbaric oxygen therapy (HBOT) for radiation-induced brain injury in a randomized controlled experimental model using adult male Wistar rats. Adult male Wistar rats were divided into four experimental groups: 0 Gy whole brain radiotherapy (WBRT) with normal baric air (NBA) treatment, 0 Gy WBRT with HBOT, 10 Gy WBRT with NBA, and 10 Gy WBRT with HBOT.
