BACKGROUND:Maintaining and improving quality of life (QOL) are important goals of anal cancer management. This disease is generally curable, with many long-term survivors.
OBJECTIVE:Long-term QOL after chemoradiation for patients with anal cancer was evaluated.
DESIGN:This was a prospective cohort study.
SETTINGS:This study used data from a prospective study of patients with anal cancer who were treated with chemoradiation between 2008 and 2013.PATIENTS: Patients with anal cancer who were treated with image-guided intensity-modulated radiation therapy were included. INTERVENTIONS: English-speaking patients completed European Organization for Research and Treatment of Cancer cancer-specific (C30) and site-specific (CR29) QOL questionnaires at baseline, at end of radiation, at 3 and 6 months, and then annually. MAIN OUTCOMES MEASURES: Long-term QOL was evaluated clinically (a change in score of ≥10 points was considered clinically significant) and statistically (using repeated-measurement analysis) by comparing the subscale scores at 1, 2, and 3 years with baseline scores. Subanalysis compared patients who received a radiation dose of 45 to 54 Gy versus 63 Gy. RESULTS: Ninety-six patients were included (median follow-up of 56.5 months). The symptom and functional scales showed a clinically significant decline at the end of treatment with improvement by 3 months after treatment. There was a long-term statistically significant decline in dyspnea, body image, bowel embarrassment, fecal incontinence, and hair loss, and there was longterm statistically and clinically significant worsening of impotence. Higher radiation dose (63 Gy) was not associated with significantly worse QOL.LIMITATIONS: Limitations included single-institution, single-arm study design, and lack of dose reconstruction (ie, analyses were based on prescribed, rather than delivered, dose).
