CCI: Charlson Comorbidity Index; ECOG: Eastern Cooperative Oncology Group; NOS: not otherwise specified; PS: performance status; SD: standard deviation; STS: soft tissue sarcoma; UK: United Kingdom; anot collected in France; bpatients with stage I, II, or III at initial diagnosis and with time from initial to advanced diagnosis greater than zero; cbecause the objective of the CCI score was to evaluate underlying comorbidity burden independent of STS, cancer was excluded from the CCI calculation for this study.
