Show moreHodgkin lymphoma and testicular cancer survivors have an increased risk of developing second primary gastrointestinal malignancies. Whether the pathogenesis of the gastrointestinal malignancies in cancer survivors differs from cancer in the general population is unknown. This thesis investigated the pathogenesis of gastrointestinal malignancies in Hodgkin lymphoma and testicular cancer survivors. Furthermore, the effectiveness of colorectal cancer surveillance is investigated in these cancer survivors. Additionally, this thesis will focus on mismatch repair deficiency, as identification of Lynch syndrome could have implications for the patients and implications for treatment choice. Show less

Show moreBeing confronted with cancer is a life-changing event, with major impact to well-being, quality of life and relationships. Cancer treatments and outcomes have improved, but possess the potential to impair reproductive and sexual function. International guidelines highlight the importance of timely discussion of sexual function and fertility deterioration resulting from treatments. In spite of these developments, practice behaviour and attitudes of health professionals have been reported to vary.The first part of this thesis demonstrates barriers among oncology professionals in the Netherlands in discussing sexual function during daily practice. In general, consensus exists regarding responsibility for addressing sexual dysfunction. Despite, the implementation of discussing sexual function as a standard of care is not carried out structural.Part two describes practice routines concerning the counselling on impaired fertility and fertility preservation for cancer patients of reproductive age. Medical oncologists and oncology nurses both reported discussing the impact of treatment on fertility. However, it was not performed in all cases and depending on factors like educational level, experience, type of hospital, prognosis and chances of fertility recovery.Furthermore, testicular cancer patients were evaluated on specific items concerning the discussion, referral and process of semen cryopreservation. Long term reproductive concerns were identified among survivors. Show less

Show morePurpose The study aimed to compare the psychosocial development of young adult survivors of childhood cancer (YACCS) with a norm group of young adults from the general population. Methods From 2017 to 2020, 558 YACCS (18-30 years, 51% female, 10.9% CNS cancer) who participated in the Dutch Childhood Cancer Survivor Study (DCCSS) LATER cohort (diagnosed 1963-2001) part 2 completed the Course of Life Questionnaire (CoLQ), assessing the achievement of milestones. Items were grouped into the scales autonomy, psychosexual, and social development. Differences between YACCS and norm group were examined with ANOVA and Cohen's d (CoLQ scales) and with logistic regression analysis and odds ratio (OR) (CoLQ items), for the total group and YACCS of CNS cancer. Results The total group of YACCS did not report a less favorable psychosocial development than the norm group. YACCS of CNS cancer scored lower than the norm group (p < 0.001) on the scales autonomy (d = - 0.36) and psychosexual (d = - 0.46). Additionally, on half of the items of autonomy (0.25 <= OR <= 0.34), psychosexual (0.30 <= OR <= 0.48), and social (0.23 <= OR <= 0.47) development, YACCS of CNS cancer were less likely (p < 0.01) than the norm group to have achieved the milestones. Conclusion Overall, psychosocial development of YACCS was as favorable as the norm, but YACCS of CNS cancer were at risk of an unfavorable psychosocial development in all domains. Monitoring psychosocial development should be included in the standards of psychosocial care, especially for CNS cancer patients and survivors, to be able to trace delay. Personalized interventions should be offered to improve the psychosocial development in an early stage. Show less
