Background: As the survival proportions for rare cancers are on average worse than for common cancers, assessing the expected remaining life years in good health becomes highly relevant. This study aimed to estimate the healthy life expectancy (HLE) of a subset of rare and common cancer survivors, and to assess the determinants of poor perceived health in rare cancer survivors.

Methods: To calculate HLE, survival data from the population-based Netherlands Cancer Registry of survivors of a rare cancer (i.

Objective: Patients with a rare cancer (RC) often have a more complex disease trajectory than patients with a common cancer. Research involving both patient groups is needed to identify differences and resemblances. In this study, we aimed to explore and compare experiences, needs and quality of life of patients with rare and common cancer throughout the disease trajectory.

Background: Gastroenteropancreatic (GEP) neuroendocrine neoplasms (NENs) comprise a group of rare malignant tumours with heterogeneous behaviour. This study aimed to assess long-term survival and prognostic factors associated with survival, in order to optimise counselling.

Patients And Methods: This population-based study included all GEP-NENs diagnosed between 1989 and 2016 in the Netherlands, selected from the Netherlands Cancer Registry.

Introduction: Epidemiological discrepancies exist between rare and common cancers. The aim of this population-based study was to compare rare versus common adult solid cancers in the Netherlands, by providing incidence, prevalence and survival rates, evaluating trends in survival and comparing individual entities within domains and families.

Methods: All adult patients with malignant solid cancers in the Netherlands between 1995 and 2019 were identified from the Netherlands Cancer Registry.
