Patient‐reported outcomes after treatment for rectal cancer—A prospective nationwide study.

Aim Method Results Conclusion While modern treatment has improved rectal cancer (RC) survival, it can cause late side effects that impact health‐related quality of life (HRQoL). The aim of this study was to evaluate HRQoL and late effects 1 year after diagnosis in patients who underwent major resection for Stage I–III RC.All patients with RC registered in the Cancer Registry of Norway between 1 January 2019 and 31 December 2020, aged ≥ 18 years, and a control group without colorectal cancer were invited to participate in the study by answering a questionnaire on HRQoL and late effects. Functional domains and symptoms were compared in different patient groups and between patients and controls.There were 558 patients and 1693 controls eligible for analysis. Response rates were 41% for patients and 23% for controls. Some differences in HRQoL were observed between treatment modalities. Major low anterior resection syndrome (LARS) was prevalent in 60.8% of patients, and was associated with lower functional and higher symptom scores compared with patients with no/minor LARS. Patients with major chronic pain [n = 86 (15.4%)] had significantly lower scores for most of the functional items and higher symptom scores than patients with no/minor chronic pain. Patients had some lower functional scores and several higher symptoms score compared with controls.Patients who suffered from major LARS or major chronic pain had significantly impaired functions and more symptoms beyond change in bowel function and pain, respectively. Identification and treatment of these patient may hopefully be beneficial for their HRQoL. [ABSTRACT FROM AUTHOR]
