Assessment of quality of life in patients with rectal cancer treated by preoperative radiotherapy: A longitudinal prospective study

One year after combined treatment for locally advanced rectal cancer, patients exhibited statistically significant improvement in some important QOL outcomes, including global QOL, despite a decrease in sexual function and body image. Any additional improvement in QOL outcome may require refinements in the RT and surgical techniques to reduce late sequelae, particularly sexual dysfunction. Our results suggest that QOL considerations do not justify sphincter-conserving approaches if locoregional tumor control would be compromised.
