Quality of life of elderly patients undergoing concomitant chemoradiation therapy for head and neck cancers, including assessment of geriatric parameters.
6100 Background: Data on the quality of life of older patients undergoing concomitant chemoradiation therapy (CCRT) for head and neck (H&N) cancer are very scarce and no study has focused specifically on them. Furthermore, no study has assessed the contribution of geriatric symptoms to their quality of life. Methods: We prospectively assessed patients aged 65 and older undergoing curative intent CCRT for H&N cancers, either alone or adjuvantly after surgery. We used the Quality of life-Radiation Therapy Instrument (QOL-RTI), with its H&N module (Trotti et al., 1998). In addition we created a 12-items senior adult questionnaire (SAQ). Patients were assessed at baseline, at 4 weeks, at the end of treatment (EOT), and 2 months after EOT (recovery). Results: Fifty patients were enrolled. Median age was 69 years (range 65-87). Eighty-two percent of patients had locally advanced stage IV disease. Twenty-eight percent had prior surgery. All patients were treated with IMRT, 92% at 70 Gy. The most frequent chemotherapy regimen was cisplatin q3wks (58%), followed by weekly carboplatin (24%). Patients had on average 4 comorbidities (CIRS-G), 54% of them a grade 3 or 4 disease. Forty-four percent were independent in IADL, and 98% were ECOG PS 0 or 1. The baseline scores were QOL-RTI: 7.72 (SD 1.36), H&N module 7.7 (SD 2.16), SAQ 8.21 (SD 1.54). At EOT, the scores were 6.22 (1.26), 4.59 (1.82), 7.38 (1.38) respectively, and at recovery 7.17 (1.25), 6.06 (1.66), 7.96 (1.16). The scores paralleled functional evolution, as 24% of patients had an ECOG PS 2 and 76% were IADL dependent at EOT; 16% ECOG 2-3 and 55% IADL dependent at recovery. Cronbach alphas for the 3 QOL measures were 0.88, 0.89, and 0.81, suggesting adequate internal consistency reliability. The SAQ was low-to-moderately correlated with the other two QOL measures (r=0.22 to 0.59) at different points of assessment. Conclusions: Older H&N cancer patients experience significant impact of CCRT on their function, and on their quality of life on all three measures. Most recover after two months, although some may take longer. A geriatric module adds significant information to the general QOL-RTI and H&N questionnaires.
