Social wellbeing, loneliness, and symptom burden in head and neck cancer survivors: a latent class analysis.

PURPOSE: To identify patterns of co-occurring symptoms in a sample of head and neck cancer (HNC) survivors; compare symptom burden among latent classes; and examine associations between symptom classes and social wellbeing outcomes.

METHODS

This cross-sectional survey of HNC survivors ≥1 year post-diagnosis was conducted in 2020 using a tumor registry at an academic medical center. Primary outcomes were loneliness and activities impairment. Participants reported 19 HNC-specific symptoms using the European Organization for Research and Treatment of Cancer HNC module (EORTC HN-43), and general cancer symptoms (sleep, pain, anxiety, depression, fatigue). Latent class analysis was used to identify subgroups with different symptom patterns. Multivariable regression models were estimated to examine associations between class membership and social wellbeing outcomes.

FINDINGS: Three hundred forty-seven survivors (mean age 65.5 ± 11.3 years; 3.72 ± 2.3 years post-diagnosis) completed the survey. Participants were predominantly male (72.6%), White (81.6%), and under age 65 years at diagnosis (59.4%). Three symptom classes were identified: (1) complex symptom burden (45%), (2) oral/sensory symptom dominant (38.9%), and (3) limited symptom impact (15.8%). Membership in the complex symptom burden class was associated with increased activity impairment (β = 28.6, SE = 3.7, p<.001) and increased loneliness (β = 1.1, SE = 0.2, p<.001) compared to the oral/sensory class (most similar to overall sample).

CONCLUSION

Elevated and complex HNC symptom burden is associated with higher levels of general cancer symptoms and risk for loneliness and reduced engagement in daily activities. Tailored survivorship care models addressing symptom profiles of HNC survivors, particularly those with complex symptom burden, are needed to improve quality of life.
