Show moreThe aim of this thesis was to investigate if a text-mining tool is suitable for collecting real-world data from electronic health records to evaluate cancer treatments in clinical practice. By investigating a range of use cases including treatments of patients with renal cell carcinoma, hepatocellular carcinoma, melanoma, breast cancer, and COVID-19, it showed that the text-mining tool is a suitable method of data needed for the evaluation of treatment patterns, effectiveness, safety, prognostic factors, and guideline adherence. The discussion showed that enhancing the data quality and actively using real-world data for treatment evaluation regarding treatment policies are some of the next steps. Show less

Show moreThis thesis focuses on treatment outcomes of high risk endometrial cancer and corresponding patients’ and clinicians’ preferences regarding adjuvant treatment decisions; molecular studies on the etiology of mismatch repair deficiency (MMRd) in intermediate and high risk endometrial cancer; and the combination of immunotherapy and PARP inhibition for the treatment of recurrent or metastatic endometrial cancer.The overall aims of this thesis were:• To evaluate health-related quality of life up to 5 years after chemoradiotherapy compared with pelvic radiotherapy alone in the adjuvant treatment of high risk endometrial cancer in the PORTEC-3 trial;• To investigate the preferences of patients and clinicians regarding the benefit-risk trade-off of the addition of chemotherapy to adjuvant pelvic radiotherapy;• To investigate the prevalence and prognosis of Lynch syndrome-associated endometrial cancer among MMRd endometrial cancers;• To evaluate the role of combined checkpoint inhibition and PARP inhibition in women with metastatic or recurrent endometrial cancer in terms of progression-free survival and toxicity in the DOMEC trial.

Show moreGemcitabine was examined as switch maintenance therapy after standard first line chemotherapy in the NVALT19 trial, which provided the first conformation of gemcitabine activity in malignant mesothelioma (MM). We describe additional analyses to confirm the prognostic value of CYFRA 21-1 and examine the prognostic value of CYFRA 21-1 in MM patients treated with gemcitabine. We also searched how gemcitabine could improve antitumor immune responses by positively modulating the immune system.In this thesis we describe a cohort of 107 malignant mesothelioma patients treated with nivolumab in the Netherlands. The real- world data of single agent PD-1 blocking were disappointing compared to previous reported single arm phase II trials. To examine clinical and peripheral blood biomarkers univariable and multivariable analyses were performed.As malignant peritoneal mesothelioma is even rarer then pleural mesothelioma, we hypothesized that centralization of care for peritoneal mesothelioma could benefit patients as they would likely receive treatment more often.Prognosis has a significant influence on the treatment preferences of patients, but prognosis of individual MM patients is variable and is hard to predict. We presented the MESOPRO score for patient with MM which are about the start with any systemic treatment. Show less

Show moreIn this thesis, the effects of a new form of immunotherapy was investigated and studied how it can be used against different types of cancers. The investigated immunotherapy is based on injecting nanoparticles loaded with various immunologically active molecules (immunomodulatory nanoparticles) that can modulate the immune system to attack cancer cells more efficiently. The effectiveness of this immunomodulatory nanoparticles have been studied on different mouse cancer models and investigated as a single treatment or in combination with other known therapies, such as chemotherapy, therapeutic cancer vaccination, or photodynamic therapy.
