Impact of neck dissection on quality of life.

OBJECTIVES: For decades, the gold standard for treatment of cervical metastasis was radical neck dissection (RND). Current oncologic philosophy allows for treatment of appropriately staged neck disease with modified radical neck dissection (MRND) or selective neck dissection (SND). The purposes of this study were to determine the impact of various forms of neck dissection on patients' quality of life (QOL) and to evaluate the responsiveness of the University of Washington (UW) QOL shoulder domain. STUDY
DESIGN: Prospective accumulation of QOL data from patients treated for head and neck cancer at UW.
METHODS: Eighty-four patients were identified from the UW QOL registry who had undergone neck dissection and had completed pretreatment and posttreatment QOL questionnaires at 6 and 12 months.
RESULTS: Compared with pretreatment scores, the MRND and RND groups reported worse shoulder function at 6 and 12 months (P<.0005). The MRND group reported greater shoulder disability at 6 months compared with the SND group (P = .002), but by 12 months, there was no difference between the two groups. Shoulder function for the RND group was worse than the SND group at 6 and 12 months (P = .004). There was a trend toward decreased pain after treatment in the SND and MRND groups. There were no significant differences in subjective appearance, activity, recreation, chewing, swallowing, or speech in the three groups after treatment.
CONCLUSIONS: Consistent with findings of published functional studies, this study confirmed that the three forms of neck dissection affect patients' QOL differently. This study demonstrates that the UW QOL shoulder domain is a responsive instrument in assessing the effect of neck dissection on shoulder function.
