Elderly with locally advanced Lung cancer: Deciding through geriatric Assessment  on the oPtimal Treatment strategy

In this single stage phase II trial we aim to demonstrate absolute increase in progression free survival at two years. . PFS will be determined as the time between randomization and disease progression, according to RECIST 1.1, death due to any cause or last patient contact alive and progression-free.

By getting more insight in the treatment-induced immunomodulatory effects, ultimately, in subsequent projects, this will allow to determine optimal immune stimulation and hence improved outcomes of subsequent durvalumab immune therapy. The hypothesis is that we can identify immune changes in stage III NSCLC patients receiving concurrent chemoradiation with protons or photons followed by durvalumab, as is done in standard clinical practice in The Netherlands.

A randomized trial: Durvalumab and low-dose PCI vs durvalumab and observation in radically treated patients with stage III NSCLC.

This is a Phase III, randomized, placebo-controlled, double-blind, multi-center study assessing the efficacy and safety of durvalumab versus placebo following SoC SBRT in patients with unresected clinical Stage I/II lymph node-negative (T1 to T3N0M0) NSCLC.

Patients continue the same immune therapy they already received and get radiotherapy to one lesion. The lesion may or may not be symptomatic, but it should be a lesion that increased in size, i.e. containing resistant cells, according to RECIST 1.1 criteria. The preferred radiotherapy dose is 24 Gy in 3 fractions (dosage on the 10 Gy isodose is allowed), but other fractionation schedules (e.g. 30 Gy/ 10 fractions, 20 Gy/ 5 fractions, 20-24 Gy / 1 fraction for SRS) are allowed if these are standard for a certain location or palliative indication in the body.

The REQUITE Plus study is an extension of the original REQUITE study. The main study objective is to establish a prospective cohort of patients undergoing radiotherapy for breast, prostate or lung cancer according to local regimens and collecting standardised radiotherapy toxicity data, non-genetic risk factor data and samples for biomarker assays for the study of determinants of radiotherapy side-effects. Furthermore, the secondary objective is to establish a comprehensive centralised database and sample collection as a resource for the prospective evaluation and validation of clinical models incorporating biomarker data to identify before treatment those cancer patients who are at risk of developing long term side-effects from radiotherapy. De REQUITE Plus extension is an follow-up study to collect additional grade of toxicity data, as well as patient-reported outcome data.

Primary intracranial germ-cell tumours in adults; evaluation and treatment protocol

The hypothesis of this study is that 6 fractions of high-precision, hypofractionated radiotherapy delivered with a higher dose per fraction is non-inferior to the standard fractionation schema and is associated with better quality of life and lower costs.

It will establish whether early adjuvant treatment with radiotherapy and adjuvant temozolomide in resected IDHmutated astrocytoma will improve outcome, and whether benefits of early treatment outweigh potential side-effects compared to active surveillance.

Evaluation methods to assess cognitive function and predict cognitive decline after treatment of meningioma are urgently needed. In this study, patients will undergo extensive cognitive testing combined with advanced brain MRI scans.

No standard re-radiation regimen has been defined for patients with recurrent glioma. In this study we determine if re-irradiation in 4 fractions is non-inferior to 10 fractions in the primary endpoint of survival after re-irradiation.
