Dynamic Quality-of-Life Trajectories After Head and Neck Reconstruction

Area of Science:

• Oncology
• Reconstructive Surgery
• Quality of Life Research

Background:

• Quality of life (QOL) is a critical outcome in cancer care, second only to survival.
• Current clinical practice assumes QOL stabilizes one year after head and neck reconstruction, influencing follow-up and trial design.

Purpose of the Study:

• To investigate the trajectory of QOL beyond the first year following head and neck reconstruction.
• To identify modifiable risk factors associated with QOL deterioration after free flap reconstruction.

Main Methods:

• A prospective cohort study involving 315 patients undergoing free flap reconstruction for head and neck disease.
• Quality of life was assessed using the University of Wisconsin QOL questionnaire, with time to deterioration (TTD) as the primary endpoint.
• Cox proportional hazards models were used to analyze risk factors for QOL deterioration.

Main Results:

• QOL remained dynamic beyond one year, with 59.9% of patients experiencing clinically meaningful changes between years 1 and 2.
• Charlson Comorbidity Index, chemotherapy, and post-operative complications were associated with QOL deterioration at 12 months.
• Complications at one year were the strongest modifiable risk factor for QOL decline.

Conclusions:

• The assumption of QOL stabilization at one year post-head and neck reconstruction is challenged by these findings.
• Prognostic QOL risk scores can help target interventions to high-risk patients, prioritizing QOL preservation.
• This study emphasizes a shift towards comprehensive survivorship care that includes QOL monitoring and management.
