Molecular testing of fine\u2010needle aspiration samples is underused, but when acquired with minimally invasive techniques could become the standard of care to obtain theranostic specimens. The aims of the current study were to identify key cytology specimen selection criteria suitable for next\u2010generation sequencing (NGS) and to determine the prevalence and spectrum of pathogenic alterations in a cohort of patients with AJCC stage IV lung cancer.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>A total of 70 adrenal gland cytology specimens with direct smears were screened to identify 56 patients with a single slide containing at least 300 total cells and 20% tumor nuclei. After DNA extraction, the NGS protocols were used to simultaneously detect mutations in &gt;2800 exonic regions in 50 key cancer genes.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>A total of 28 specimens produced acceptable NGS results. Specimens with a combined critical cell mass (&gt;5000 viable cells) and a DNA concentration &gt;5 ng\/\u00b5L resulted in a 95% chance of successful sequencing. A total of 37 pathogenic alterations were identified in 10 genes and in 25 patients (85%). A pathogenic alteration (\u22651) linked to available or developing targeted therapies was revealed in 50% of cases.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>The data from the current study demonstrate that theranostic NGS can be applied to adrenal gland metastasis using routine cytologic smear specimens. The characteristics of such smears could be evaluated during onsite adequacy assessment by cytopathology professionals. This model greatly augments the opportunity for customized genotype\u2010directed therapy from minimally invasive techniques. <jats:bold><jats:italic>Cancer (Cancer Cytopathol)<\/jats:italic>
