“Patients who underwent adjuvant chemotherapy for pulmonary large cell neuroendocrine carcinomas demonstrated poorer 3-year survival than those who did not undergo adjuvant treatment, according to study results presented at the American Association for Thoracic Surgery Annual Meeting.
“ ‘We did not see any particular subset of patients who may benefit from this treatment,’ researcher Pier Luigi Filosso, MD, of the University of Torino in Italy, said during a presentation.
“Filosso and colleagues conducted a retrospective cohort study to determine the impact of adjuvant chemotherapy in patients with resected large cell neuroendocrine carcinomas (LCNEC). The analysis included 400 patients with LCNEC who underwent surgery between 1992 and 2014 at one of 14 institutions worldwide.
“Researchers used the Kaplan-Meier method to estimate OS after resection. Propensity score for the likelihood of receipt of adjuvant chemotherapy was estimated based on patient age, gender, prior malignancy, ECOG performance status, TNM stage and year of surgery.”
