Health quality of life and colorectal cancer.
BACKGROUND
Quality of life associated with cancer and radiation treatment includes the dimensions of psychologic and physical well-being, nutrition concerns/side effects, and radiation treatment-related anxiety/adjustment. An understanding of the impact of colorectal cancer and radiation treatment on these aspects of health quality of life can be reached by comparing this diagnostic group to others undergoing similar treatment.


METHODS
Thirty-six patients with colorectal cancers, 41 with uterocervical cancers, 43 with genitourinary tumors, 13 with leukemia or bone metastasis, and 129 with head and neck cancers undergoing radiation therapy provided complete health quality of life index (QLI-RT) data during weeks 1 and 3 of treatment and at the first follow-up visit after treatment completion. The QLI-RT was found to be reliable and valid.


RESULTS
Those with colorectal cancer had similar QLI-RT summary scores as the other groups at the beginning of treatment and during the follow-up period. QLI-RT scores tended to range from 62 to 84 for the summary score and individual-item scores; this was a narrow span considering the QLI-RT uses a 0-100-mm linear analog-response scale. The exceptions were strength, which elicited scores in the 46-68 range and a couple of responses to worrying about radiation therapy. The largest change in QLI-RT score in relation to the treatment trajectory was 11 mm.


CONCLUSIONS
These findings tend to support the notion that patients with cancer try to maintain health quality of life at an acceptable level despite the occurrence of stressful negative events. Future research should explore the stable versus dynamic attributes of health quality of life to learn more about the factors that contribute to the adaptive process that maintains such quality of life at an acceptable level.
