Speech Impairment Dominates Early Quality of Life After Oral Cancer Surgery

Postoperative quality of life (QoL) in the first week after oral cancer surgery appears to be driven most strongly by speech dysfunction, operating through both direct and multilayered psychosocial pathways, according to a study published in Health and Quality of Life Outcomes.

In a structural equation model adjusting for tumor stage, speech disorder demonstrated the largest total negative association with QoL (β, −0.824), underscoring its central role in early recovery and its downstream effects on self-esteem, social alienation, and body image.

This cross-sectional analysis included 401 participants assessed within 7 days of surgery from an initial cohort of 487 screened patients, yielding an enrollment rate of 91.4% among eligible patients and a retention rate of 97.8%. The sample was predominantly male (90.8%), married (94.8%), and aged 51 to 60 years (43.4%). Most participants had squamous cell carcinoma (96.3%), with the tongue as the most frequent lesion site (54.1%), and were classified as stage II (34.7%). The mean QoL score was 65.95±11.64.

Nonparametric analyses showed significant differences in QoL by marital status, residential method, caregiver identity, tumor stage, receipt of chemoradiotherapy, and postoperative complications (all P <.05). Tumor stage exerted the greatest clinical impact, with stage IV disease associated with the lowest QoL (58.21±14.02). In multivariable regression, tumor stage (β, −0.413, P <.001) outweighed demographic factors, justifying its inclusion as the sole covariate in subsequent modeling.

Correlation analyses highlighted strong interrelationships among functional and psychosocial domains. QoL was inversely correlated with speech disorder (r, −0.681), body image disturbance (r, −0.566), and social alienation (r, −0.557), and positively correlated with self-esteem (r, 0.535; all P <.01). These findings suggested that impaired communication may precipitate internal and social consequences that amplify perceived health burden.

In the final structural equation model, body image showed the strongest direct association with QoL (β, −0.609; P <.001), while self-esteem and social alienation influenced QoL only indirectly through body image. Speech disorder maintained a substantial direct effect (β, −0.446; P <.001) and additional indirect effects through 4 mediated pathways involving self-esteem, social alienation, and body image.

These data indicate that early postoperative QoL in oral cancer is shaped by complex, sequential interactions linking speech impairment to psychosocial vulnerability and altered body image. "These findings underscore the importance of a multidimensional survivorship model and point to the potential value of early and integrated interventions that combine functional rehabilitation with psychosocial support," said the authors. "Future research should further explore these pathways using longitudinal and interventional designs to validate the associations observed and to inform clinical application."
