RESUMEN
Many oncology centers provide integrative oncology (IO) care, many within palliative care settings. The primary study objective was to examine the impact of IO-palliative patient-tailored program on quality of life (QoL) among patients with advanced cancer. In this pragmatic prospective controlled study, patients with advanced cancer undergoing chemotherapy/palliative care were referred by their oncology healthcare providers to an integrative physician (IP) consultation and weekly IO treatments. Patients with high adherence to integrative care (AIC; ≥ 4 IO sessions/6 weeks) were compared with moderate (2-3 sessions) or low AIC patients (regarded as control group). Outcomes were assessed at 6- and 12-week follow-up with Edmonton Symptom Assessment Scale (ESAS) and EORTC QLQ-C30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire) tools. Change in QoL scores (ESAS fatigue in particular) was considered a primary study outcome. Of 225 eligible patients, 153 underwent baseline and 6-week optimal assessment (high AIC, 100; moderate AIC, 22; low AIC, 31). High AIC patients reported greater improvement on ESAS scores for fatigue (vs. low-moderate AIC, P < 0.001), depression (vs. moderate AIC, P = 0.01) at 6 weeks, and sleep (P = 0.007) at 12 weeks. High AIC patients had significantly improved EORTC global health status/QoL at 6 weeks (vs. moderate-low AIC, P = 0.01), cognitive functioning (vs. moderate AIC, P = 0.043), and social functioning (vs. moderate AIC, P = 0.032). High AIC patients had lower rates of hospitalizations at 12 weeks (19% vs. 35% in low AIC, P = 0.02; 44% in moderate AIC, P = 0.003), hospitalization days (vs. low AIC, P = 0.003), and opioid use (vs. low AIC, P < 0.001). High adherence to integrative care was associated with a significant effect on fatigue, depression, global QoL at 6 weeks, and need for hospitalizations at 12 weeks.
