ABSTRACT

Objectives: To determine the prevalence of neuropathic and mixed pain in the population treated in the Oncology Service of the catchment area (Cadiz-San Fernando) of the Puerta del Mar University Hospital. Patients with cancer reporting pain and who had not received prior oncological treatment that could have caused the pain were included. We also aimed to determine the demographic, clinical and psychiatric comorbidities associated with the presence of neuropathic and mixed pain in these patients. Material and methods: Design: Observational, cross-sectional study. Setting: Catchment area of the Puerta del Mar University Hospital (Cadiz-S. Fernando), which attends a population of 242,723 people. Study subjects: Patients diagnosed with cancer who reported pain and who had not received prior oncological treatment that could potentially have caused the pain attended in the Outpatient Oncology Department of the Puerta del Mar University Hospital. Data collection The following scales were used the validated Spanish version of the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) scale for the diagnosis of neuropathic pain, the Hospital Anxiety and Depression Scale (HADS) and the Brief Pain Inventory Short Form (BPI-SF). A questionnaire was employed to collect sociodemographic and clinical variables. Analysis: The prevalence of neuropathic and mixed pain (± 95% CI) was calculated in the population attending the Outpatient Oncology Department of the Puerta del Mar University Hospital (AU)
