Ethics approval and consent to participate
: A written informed consent was signed by the patients for the use of their resected tissue samples for medical research. According to the Dutch legislation, the approval of local ethics committee for medical research with patient data and tissue samples is not mandatory. At the time of tissue collection for this study, ethical approval was deemed unnecessary not only because of this legislation but also because the tissue collection did not determine the course of the surgery nor of the preceding and follow-up treatment, and the investigated samples would otherwise have been discarded. All tissue samples and patient data were anonymized for the members of the experimental research team, and these members did not have any contact with the operated patients.
: The authors declare that they have no competing interests.
