- W2891870935 abstract "e21530 Background: In geriatric assessments, comorbidity is often assessed with tools such as the Charlson comorbidity index (CCI) and the Cumulative Illness Rating Scale-Geriatrics (CIRS-G). In studies of older patients with colorectal cancer (CRC), comorbidity was mainly measured using the CCI, and inconsistent results about the correlation comorbidity with overall survival (OS) were found. In order to refine our understanding of the impact of comorbidity, we evaluated its correlation with OS using the CIRS-G and heat maps to elicit the subgroups with the highest impact. Methods: We retrospectively reviewed 153 consecutive patients from the Total Cancer Care database, aged ≥65 with stage 4 CRC, who underwent chemotherapy at Moffitt Cancer Center from 2000 to 2015. The association between CIRS-G scores and OS was examined by the Cox proportional hazards regression model. Results: Median age at diagnosis was 71 years. Forty-eight % of patients had an ECOG PS of 0. Median MAX2 score of chemotherapies was 0.119. Median total score of CIRS-G was 8 (1-20) and median severity index was 0.57 (0.07-1.43). The most common comorbidities were vascular, EENT and larynx, and respiratory diseases. Eleven patients had 1 comorbidity and 1 patient had 2 comorbidities at level 4 severity. Median OS of all patients was 25.1 months (95% CI 21.2-27.6). In univariate analysis, the number of CIRS-G level 4 comorbidities was a significant worse prognostic factor for OS (0 vs 1 or 2, HR 2.16, p = 0.017). In multivariate analysis, ECOG PS ≥2, poorly differentiated histology, age at diagnosis and numbers of CIRS-G level 4 comorbidities were significant worse prognostic factors for OS. ECOG PS ≥2 and age at diagnosis were significant worse prognostic factors for unplanned hospitalization. Conclusions: The OS in the elderly metastatic CRC patients was good and similar to the general population with this disease. The number of CIRS-G level 4 comorbidities was associated with worse OS but no specific CIRS-G category was individually associated with OS." @default.
