HN Tumor Biobank

NameHead and Neck Tumor Biobank
AcronymHN Tumor Biobank
Type☒ Disease specific
Diseases studied(suspected) squamous cell carcinoma of the oropharynx, larynx, hypopharynx, nasopharynx or oral cavity
DescriptionIn HNSCC patients, advances in molecular biology with the development of genomic and proteomic approaches have also demonstrated distinct prognostic patient subsets, beyond those defined by traditional clinical-pathological factors such as tumor subsite and stage.

Predictive models are needed to deal with multiple predictive factors and that the inclusion of gene-signature data and/or other molecular biomarkers from fresh-frozen tumor tissue will improve outcome prediction. However, validation of these biomarkers and other emerging prognostic factors in large prospective cohort studies is required before these markers can be introduced as standard clinical practice.

Collect primary tumor biopsy material for storage in a HN Tumor Biobank from all patients with Head and Neck Squamous Cell Carcinoma (HNSCC). These biopsies will be stored fresh-frozen until further analysis.

OPTIMA

NameEvaluation of potential biomarkers during irinotecan-based systemic treatment for colorectal cancer
AcronymOPTIMA Study
Type☒ Cohort
☒ Disease specific
☒ Hospital
☒ Longitudinal
Diseases studiedAdvanced Colorectal Cancer
DescriptionBackground
Patients with advanced colorectal cancer (CRC) commonly receive irinotecan-based systemic treatment to alleviate symptoms, improve quality of life (QoL), and prolong overall survival (OS). However, predicting efficacy and toxicity of the treatment is challenging.
Previous research indicated an association between the tumor molecular profile and response to irinotecan-based systemic treatment.
Moreover, the UGT1A1 genotype of the patient, and the activity of the gut microbial enzyme β-glucuronidase (GUS) have been suggested as biomarkers for the development of systemic (e.g. neutropenia) and gastrointestinal toxicity (e.g. diarrhea) respectively.

Therefore, the OPTIMA study will evaluate in patients with advanced CRC:
1. whether tumor molecular profiling can predict the efficacy of irinotecan-based systemic treatment;
2. whether high bacterial GUS enzyme activity is associated with increased gastrointestinal toxicity, decreased QoL and OS; as well as
3. the safety of a 70% irinotecan dose intensity in UGT1A1 poor metabolizers (PMs).
Methods
This prospective, observational, multi-center cohort study will include patients with advanced CRC scheduled for irinotecan-based systemic treatment. Archived tumor tissue and routine CT/MRI scans at baseline and after four cycles will be used to investigate the association of tumor molecular profile and treatment response according to RECIST.
Before treatment initiation, germline DNA obtained from whole blood will be genotyped using PCR to determine the UGT1A1*28 genotype, followed by 30% irinotecan dose reduction in UGT1A1 PMs.
Bacterial GUS activity will be quantified in fecal samples collected before and during treatment by means of an enzyme activity assay and will be related to patient-reported gastrointestinal toxicity (mainly diarrhea).
Additionally, patients will fill in questionnaires concerning QoL, medication use, medical history and comorbidities, dietary habits, as well as physical performance. OS will be documented, capturing the duration from the start of treatment until death from any cause.
Discussion
Results obtained in the context of the OPTIMA study are expected to contribute to the optimization of efficacy and the reduction of toxicity of irinotecan-based systemic treatment, thereby potentially improving QoL of patients.
Given that maintaining QoL is particularly critical in the palliative setting, the OPTIMA study has the potential to be of significant benefit for patients and their caregivers.

STAR

NameSTudying Ageing in Rheumatoid arthritis (STAR) stored serum
AcronymSTAR stored serum
Type☒ Case-Control
☒ Cross-sectional
Diseases studiedICD-10 M06.9 Rheumatoid arthritis
DescriptionThe goal of the STudying Ageing in Rheumatoid arthritis (STAR) study is to gain insight into the effect of ageing on the result of disease activity measures, decline in cognition, physical activity and performance.

In total, 420 patients with RA will be compared to 420 population controls between 55 and 85 years of age.

In 180 participants (90 patients with RA and 90 population controls) one blood sample will be collected for the determination of CRP and ESR values, and serum will be stored for potential future analyses.

STRONG II

NameStereotactic body radiation therapy after chemotherapy for unresectable perihilar cholangiocarcinoma: a multicenter phase II trial
AcronymSTRONG II
Type☒ Cohort
☒ Disease specific
☒ Hospital
☒ Longitudinal
Diseases studiedunresectable perihilar cholangiocarcinoma (XH43E4)
DescriptionFor patients with perihilar cholangiocarcinoma (pCCA), surgery is the only treatment modality that can result in cure. Unfortunately, most patients have unresectable tumors at presentation. The standard treatment for patients with unresectable pCCA is palliative chemotherapy (cisplatin and gemcitabine) which yields an estimated median overall survival (OS) of 12 months.

In 2020 we completed a feasibility and phase I trial (STRONG 1) in six patients with stereotactic body radiation therapy (SBRT), delivered after chemotherapy to test its tolerability in patients with unresectable pCCA.
We observed no dose-limiting toxicity (DLT), defined as grade ≥ 4 hepatobiliary or grade ≥ 3 gastrointestinal toxicity. The 12-month local tumor control rate was 80%, median survival was not reached, and there were no substantial changes in quality of life (QoL).

The objective of the study is to confirm the efficacy of SBRT in a larger cohort of patients regarding local tumor control, toxicity, progression-free survival (PFS), OS, and QoL. Additionally, this study will include a translational part to explore the value of peripheral immunodynamics in predicting survival.

Type☒ Disease specific
Diseases studiedMalignant neoplasm of rectum (C20)
DescriptionProspective validation of a predictive model for pathologic complete response after chemoradiotherapy in rectal
cancer: A prognostic study.
Objective: The long-term research objective is to be able to select rectum cancer patients who could receive a less invasive
treatment. If prediction of response is possible, surgery may be avoided when complete response after chemoradiotherapy is expected or performed with smaller incisions if stage reduction is significant. This support decision
system helps to individualize patient treatment and can improve the quality of life for the patient.
