| Zusammenfassung: | <jats:p> 566 </jats:p><jats:p> Background: In most patients (pts) with metastatic colorectal cancer, a 3-drug combination of a fluoropyrimidine, oxaliplatin (ox) or irinotecan (iri), and a monoclonal antibody is considered standard 1st-line treatment. However, in elderly pts this choice remains controversial. After registration of bevacizumab (bev) in Germany in 2005, this observational study was initiated in pts receiving bev with various first-line chemotherapy (CT) regimens to evaluate the disease profile and efficacy of bev in patients with metastatic colorectal cancer. </jats:p><jats:p> Methods: Eligibility criteria focused on M1 disease without prior palliative CT. The choice of CT regimen was at the physician’s discretion. Predefined efficacy endpoints were: response rate (RR), progression-free survival (PFS) and overall survival (OS). Pts were followed for up to 6 years (y). Two pt subgroups were analyzed: ≥70 y and ≥75 y; the ≥75 y group is the focus of this abstract. </jats:p><jats:p> Results: 1777 eligible pts were enrolled at 261 sites from Jan 2005 to June 2009, 206 (12%) of whom were aged ≥75 y. These elderly pts did not differ greatly vs younger pts in time from initial diagnosis or time to first relapse, pT, pN and M stage, site of metastasis, grading, CEA, WBC, blood pressure, or prior adjuvant therapy. However, fewer elderly pts had >1 involved organ site (28% of pts ≥75 y vs. 32% of pts ≥70 y) and elderly pts had significantly poorer performance status (ECOG 0 in 29% of pts ≥75 y vs. 39% of pts ≥70 y). Bev treatment duration was similar in elderly and younger pts, but differences in CT usage were observed (Table). Response and survival outcomes were significantly worse in those aged ≥75 y. </jats:p><jats:p> Conclusions: Bev-based treatment combinations can be used successfully in pts aged ≥75 y. However, PFS and OS are significantly shorter in pts aged ≥75 y vs younger pts, probably because of greater comorbidity and possibly because of less intensive treatment in the elderly. </jats:p><jats:p> [Table: see text] </jats:p> |
