Genome-wide association studies (GWAS) have been successful in identifying common genetic variation involved in susceptibility to etiologically complex disease. We conducted a GWAS to identify common genetic variation involved in susceptibility to upper aero-digestive tract (UADT) cancers. Genome-wide genotyping was carried out using the Illumina(More)
BACKGROUND Microsomal epoxide hydrolase (mEH) is an enzyme involved in the metabolism of (pre)carcinogens in tobacco smoke. We investigated whether functional genetic polymorphisms in mEH may have a risk-modifying effect on head and neck carcinogenesis. METHODS Blood from 429 patients with oral, pharyngeal, and laryngeal carcinoma and 419 healthy subjects(More)
UDP-glucuronosyltransferase 1A1 (UGT1A1) is an enzyme which catalyses not only the glucuronidation of tobacco smoke carcinogens like benzopyrene, but also of the endogenous substrate bilirubin. Bilirubin for a long time was considered to be only a toxic waste product of hemoglobin degradation, but recent findings have shown that bilirubin is a potent(More)
Combined analysis of diagnostic and therapeutic management of neck metastases of carcinoma of unknown primary origin (‘true CUP’) in two European tertiary referral centers (University Medical Centers of Maastricht, NL and Cologne, D) to contribute to the ongoing discussion on management in CUP. Retrospective analysis of 29 (Maastricht) and 22 (Cologne) true(More)
BACKGROUND The purpose of this study was to determine the relationship between swallow-specific quality of life (QOL) using the MD Anderson Dysphagia Inventory (MDADI) and the swallowing function using a standardized fiber-optic endoscopic evaluation of swallowing (FEES) protocol in patients with dysphagia with head and neck cancer. METHODS Sixty-three(More)
BACKGROUND UGT1A7 is an enzyme involved in the metabolism of (pre)carcinogens present in tobacco smoke. We investigated whether genetic polymorphisms in UGT1A7, with predicted altered enzyme activity, may have a risk-modifying effect on head and neck carcinogenesis. METHODS Blood samples from 427 patients with oral, pharyngeal, and laryngeal carcinoma and(More)
The purpose of this study was to investigate the feasibility of an online self-management application (OncoKompas) among cancer survivors. In OncoKompas, cancer survivors can monitor their quality of life (QOL) via participant reported outcomes (PROs) (“Measure”), which is followed by automatically generated individually tailored feedback (“Learn”) and(More)
We conducted a genome-wide association study of oral cavity and pharyngeal cancer in 6,034 cases and 6,585 controls from Europe, North America and South America. We detected eight significantly associated loci (P < 5 × 10-8), seven of which are new for these cancer sites. Oral and pharyngeal cancers combined were associated with loci at 6p21.32 (rs3828805,(More)
PURPOSE To find molecular markers from expression profiling data to predict recurrence of laryngeal cancer after radiotherapy. EXPERIMENTAL DESIGN We generated gene expression data on pre-treatment biopsies from 52 larynx cancer patients. Patients developing a local recurrence were matched for T-stage, subsite, treatment, gender and age with(More)
BACKGROUND Cyclooxygenase-2 (COX-2) is an enzyme involved in the synthesis of prostaglandins and thromboxanes, which are regulators of processes such as inflammation, cell proliferation, and angiogenesis, all relevant for cancer development. We investigated whether functional genetic polymorphisms in COX-2 may have a risk-modifying effect on head and neck(More)
