Assessment of Quality of Life in Rectal Cancer with Organ-Preservation Treatment: Are We There yet?

Rectal cancer is a common cancer and shows an increased incidence with older age. Although the gold standard treatment is surgical excision, minimally invasive approaches are increasingly used and organ preservation is becoming a reasonable approach. The conservative treatment approach includes local excision, external beam radiotherapy and brachytherapy. However, these all carry a risk of side-effects. It is crucial to provide patients with information to quantify the improvement or detriment in quality of life with their cancer treatment. This can only be done with patient-reported outcome measures (PROMs) as tools within current and future trials. Colorectal cancer has numerous publications with specific PROMs. However, PROMs reporting in rectal cancer is more sparse; PROMs are generally extrapolated from colorectal cancer. Rectal PROMs trials hold small population samples and PROMs as an end point is scarce. We present a review of recent literature based on the PROMs reporting of quality of life for rectal cancer patients and introduce the CITRuS trial as an innovative feasibility study related to electronic PROMs data collection.
