Patients ≤ 65 years had a significantly higher representation of females (p = 0.0021), more frequent familial cancer aggregation (p = 0.028) and a lower incidence of squamous cell carcinoma (p = 0.0133). When excluding pure carcinoid tumours, a significantly higher proportion of the younger patients presented with advanced stage disease (p = 0.0392). Combined modality therapy was more common in younger patients (p = 0.0009), while chemotherapy appeared less prevalent among the elderly (p = 0.0015).
