RESUMEN

INTRODUCTION: Colorectal cancer (CRC) is a disease of older patients, but evidence-based guidelines for chemotherapy in older patients are scarce. Geriatric assessment (GA) evaluates a patient's functional status (FS) and helps in decision-making when choosing chemotherapy for older patients. However, the change of FS during chemotherapy is rarely studied as GA is mostly performed once instead of sequentially. METHODS: We performed a subgroup analysis of a prospective, multicenter study EpiReal 75. Patients aged ≥75 years with gastrointestinal malignancy prior to initiation of chemotherapy or receiving palliative chemotherapy were screened. We defined geriatric core assessments including the Eastern Cooperative Oncology Group score, Barthel's activities of daily living (ADL) scale, Lawton's instrumental activities of daily living (IADL) scale, and G-8 questionnaire, which were performed at baseline and repeated every 3 months. Quality of life (QoL) assessed by QLQ-C30 questionnaire was also re-evaluated every 3 months. We defined any deterioration in any of the geriatric parameters as unstable in the corresponding function. RESULTS: 28 patients with CRC were enrolled between April 2014 and December 2018. 20 patients were evaluable for statistical analysis with a mean age of 78.5 years (range, 75-88). Most patients received chemotherapy in palliative setting. During 3 months of chemotherapy, 25% of patients became more dependent as measured by ADL or IADL. During a median follow-up of 15 months, patients with unstable ADL or IADL had a significantly shorter overall survival (OS) than those with stable ADL or IADL (plogrank = 0.0055 and 0.0253, respectively), without a significant difference in progression-free survival (PFS). Also, unstable IADL correlated with a deterioration in aspects of QoL such as role functioning and emotional functioning (p = 0.0189 and 0.0239, respectively). 20% of patients experienced treatment-related grade 3 adverse events (AEs), no grade 4-5 AEs occurred. CONCLUSION: Sequential GA revealed changes in FS in older patients with CRC receiving chemotherapy. A deterioration of FS during chemotherapy did not influence PFS but had a negative impact on OS and QoL. It is therefore important to maintain FS in older patients with cancer, and regular performance of geriatric core assessments should be encouraged in the clinical practice.
