Abstract
Background:
Brain is one of the common sites of metastasis in patients with lung cancer. This is more
likely to be present in cases with small cell lung cancer (SCLC) than those with non-small cell
lung cancer (NSCLC).
Objective:
To estimate the incidence of silent brain metastasis in patients with NSCLC (clinically
stages II, III and IV at presentation).Patients and methods: A prospective study was conducted
during the period from July 2012 to January 2016 for 942 patients presented in Sohag University
Clinical Oncology Department, Sohag Cancer Center and Sohag Health Insurance. All of them
had histopathological prove of NSCLC and contrast-enhanced conventional magnetic resonance
imaging (MRI) of the brain was done for all patients at presentation.
