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)
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)
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)
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 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 Combinations of genetic polymorphisms in biotransformation enzymes might modify the individual risk for head and neck cancer. METHODS Blood from 432 patients with head and neck cancer and 437 controls was investigated for genetic polymorphisms in 9 different phase I and II biotransformation enzymes. Analysis of the risk-modifying effect was(More)
BACKGROUND Sequence variants located at 15q25 have been associated with lung cancer and propensity to smoke. We recently reported an association between rs16969968 and risk of upper aerodigestive tract (UADT) cancers (oral cavity, oropharynx, hypopharynx, larynx, and esophagus) in women (OR = 1.24, P = 0.003) with little effect in men (OR = 1.04, P = 0.35).(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)
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)
PURPOSE Current assessment of lymph node metastasis in patients with head and neck squamous cell carcinoma is not accurate enough to prevent overtreatment. The aim of this study was validation of a gene expression signature for distinguishing metastasizing (N+) from nonmetastasizing (N0) squamous cell carcinoma of the oral cavity (OSCC) and oropharynx(More)
