Quality of life of Japanese elderly oral cancer patients during the perioperative period.

Japan's aging society has an increasing incidence of oral cancer. This study investigated perioperative changes in quality of life (QoL) among 172 oral cancer patients (elderly ≥75 years vs non-elderly <75 years), pre-treatment, at treatment completion, and at 1, 3, and 6 months post-treatment, using the following Functional Assessment of Cancer Therapy - Head and Neck (FACT-H&N) subscales: physical well-being (PWB), social/family well-being (SWB), emotional well-being (EWB), functional well-being (FWB), additional head- and neck-specific concerns (H&N). SWB (P=0.026), H&N (P=0.024), and total FACT-H&N (P=0.009) scores were significantly lower in the elderly group than in the non-elderly group at 6 months post-treatment, especially for mastication items (H&N1, P=0.047; H&N11, P=0.004), but not for swallowing items (H&N5 and H&N7, both P> 0.05). PWB (P= 0.004), EWB (P< 0.001), and FWB (P= 0.022) scores in the non-elderly group were significantly higher at 6 months post-treatment than before treatment. In the elderly group, no subscale showed a better score at 6 months post-treatment. Post-treatment QoL in elderly oral cancer patients did not improve, unlike in non-elderly patients.
