ABSTRACT
Brain metastases (BMs) are the most common intracranial tumors and non-small cell lung cancer (NSCLC) are responsible for BM more than any other solid tumor. Its frequency is increasing due to of the availability of new imaging techniques, earlier diagnosis and improvement in treatment techniques and survival rates. NSCLC patients with BM represent heterogeneous prognostic group. The possibility of better prognostic stratification associated with more systemic therapy options and imaging and radiation technology advances have led to an increment of evaluation and indication of local ablative radiotherapy. The definite increment in quality of life and the potential overall survival (OS) benefit of its indication must be balanced with eventual higher risk of brain disseminated disease when whole brain irradiation is postponed. Therefore, a multidisciplinary evaluation is recommended to refine and personalize the therapeutic approach. The development of clinical nomograms or evaluation of circulating tumor cells/tumoral DNA that predict the survival free of new lesions may be the tools that will warranty further optimization of the treatment of NSCLC patients with BM. In this review, we report the main aspects of diagnosis, prognosis and therapeutic options and dilemmas evolving local ablative radiotherapy essentially based on seminal, updated prospective studies and ongoing trials.
ABSTRACT
Primary MALT lymphoma arising at the dura is a rare circumstance with no categorical therapeutic plan in literature. There are few reports available with different treatment courses. Here, we report two cases with a long-term follow-up after the same pattern of management and review the literature.
