Also, patients in this study likely had lower tumor burden compared with patients who participated in earlier studies as a result of better imaging at diagnosis as well as the coincidental detection of small cancers when patients undergo diagnostic imaging for other indications.

The median overall survival was As of December 15,median follow-up for surviving patients was cqlgb Thus, calg analyses should be considered exploratory. Patients were 18 years or older with an Eastern Cooperative Oncology Group performance status of 0 to 1 and normal hepatic, renal, and hematologic laboratory values.

Eli Lilly provided the cetuximab. Drafting of the manuscript: PubMed Google Scholar Crossref. This analysis included only caogb without a mutated KRAS gene, which is a known biomarker of response to certain colorectal cancer therapies cetuximab is approved only for treating KRAS wild-type tumors.


Eligible patients had pathology-documented untreated locally advanced or metastatic colorectal cancer, although measurable disease tumor that could be quantified was not require.

The primary statistical analyses were 2-sided tests of superiority comparing cetuximab vs calg with regard to the primary and main secondary outcomes among patients whose tumors were determined to be KRAS wt exon 2, codons 12,13 by Southwest Oncology Group review using intention-to-treat analyses.

The primary end point of overall survival was defined as time of study entry until death. To determine if the callgb of cetuximab vs bevacizumab to the combination of leucovorin, fluorouracil, and oxaliplatin mFOLFOX6 regimen or the combination of leucovorin, fluorouracil, and irinotecan FOLFIRI regimen is superior as first-line therapy in advanced or metastatic KRAS wild-type wt colorectal cancer.

Thirty-one patients calbg while receiving the protocol therapy: The median progression-free survival was Better chemotherapeutic regimens, patient selection, and changing multidisciplinary management likely contributed to these outcomes as did the exclusion of patients with KRAS mutations.
