title: Staging practices of primary non-small-cell lung cancer: a literature review.
abstract: Lung cancer is the most frequent cause of cancer deaths worldwide, and non-small-cell lung cancer (NSCLC) accounts for approximately 80% of all cases. Stage at diagnosis is the most important indicator of survival. Various non-invasive and invasive procedures are available for NSCLC staging. However, the precise indications for performing these procedures remain controversial. There is no evidence about the level of variability in practice of imaging and invasive procedures used for NSCLC staging. Their high costs contribute to the controversy about their use. We performed a literature search on the MEDLINE database to identify studies reporting practice of staging for a nonselected group of patients with NSCLC. Only seven studies enrolling between 185 and 2,071 patients reported NSCLC staging practices. These studies were reviewed to identify patterns in practice of staging work-up and consecutive treatment. Lack of detailed reporting limits the interpretation of the results. Based on our review, future investigations should be conducted to determine the extent of variation in patterns of physician practices of NSCLC staging and their impact on the treatment practice or patient survival.
