Patient-reported symptoms and stepwise symptom management in patients on epidermal growth factor inhibitors: A retrospective, descriptive cohort study.

Adverse events (AEs) of epidermal growth factor inhibitors (EGFRi) influence well-being with a risk to dose modifications (DMs). Hereby, clinical benefit of treatment might be affected. This retrospective cohort study was set up to gain insight into the suitability and added value of a patient-reported outcome measurement tool (PROM), together with a stepwise intervention management plan for EGFRi-related AEs in daily practice. The primary objective was to gain insight into total treatment duration and DMs, and the secondary objective to gain insight into patient-reported symptoms and well-being as well as healthcare professional-reported AEs. Sixty-eight patients on cetuximab and 19 on panitumumab treatment were included for analysis; 69% had squamous cell carcinoma of head and neck (SCCHN) and 26% metastatic colorectal carcinoma. DMs due to AEs occurred in 39% of the patients and dose discontinuations in 22%. Especially anorexia, dysphagia, oral pain and skin changes led to a decreased well-being. In patients on EGFRi, application of PROMs together with a stepwise symptom management plan enhances early recognition of symptom burden, pro-active symptom management and effect evaluation of interventions performed whereby well-being recovers. Since only SCCHN patients discontinued treatment due to AEs, patient-centred care focused on radiotherapy-related AEs, creates opportunities for amelioration.
