In their study, Halle and colleagues found that lymph node negative cervical cancer patients with high expression of ectodomain EGFR isoforms had a high probability of relapse after chemoradiotherapy, whereas the EGFR tyrosine kinase activity was of minor importance. Gene expression profiles of the tumors were used to further explore these findings. The study may shed light on possible mechanisms of treatment resistance in EGFR trials and point to the expression of ectodomain EGFR isoforms as a novel and well-needed biomarker of relapse for this group of patients.
The patients were treated at the Radium Hospital and clinical collaborators were Gunnar B. Kristensen and the radiotherapy team at the section for Gynecological Oncology. Collaborators in statistics and bioinformatics were Marit Holden at the Norwegian Computing Center and Trevor Clancy at Department of Tumorbiology.
