In early-stage patients, no statistically significant differences in disease-free survival were found with the addition of preoperative or adjuvant chemotherapy to surgery. In this trial, in which the treatment decision was made before surgery, more patients were able to receive preoperative than adjuvant treatment.
Patients homozygous for the ERCC1 118 C allele demonstrated a significantly better survival. ERCC1 SNP assessment could be an important component of tailored chemotherapy trials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
