ABSTRACT
In this paper we review clinical and genetic aspects of testicular germ cell tumours (TGCTs). TGCT is the most common type of malignant disorder in men aged 1540 years. Its incidence has increased sharply in recent years. Fortunately, survival of patients with TGCT has improved enormously, which can chiefly be attributed to the cisplatin-based polychemotherapy that was introduced in the nineteen eighties to treat patients with metastasized TGCT. In addition, new strategies have been developed in the surgical approach to metastasized/non-metastasized TGCT and alterations have been made to the radiotherapy technique and radiation dose for seminoma. Family history of TGCT is among the strongest risk factors for this tumour type. Although this fact and others suggest the existence of genetic predisposition to develop TGCT, no germline mutations conferring high risk of developing TGCT have been identified so far. A small deletion, referred to as gr/gr, identified on the Y chromosome is probably associated with only a modest increase in TGCT risk, and linkage of familial TGCT to the Xq27 region has not been confirmed yet. Whether highly penetrant TGCT-predisposing mutations truly exist or familial clustering of TGCT can be explained by combinations of weak predispositions, shared in utero or postnatal risks factors and coincidental somatic mutations is an intriguing puzzle, still waiting to be solved.
ABSTRACT
This study examines the prevalence of problems in children within four months after a parent's cancer diagnosis (T1) and six (T2) and twelve months (T3) afterwards. Sixty-nine ill parents and 57 spouses completed the Child Behavior Checklist for 57 primary school (aged 4-11 years) and 66 adolescent children (aged 12-18 years). Adolescents completed the self-report version. Children's functioning was compared to that of the norm group and a sample of families that were confronted with parental cancer between one to five years before study participation (retrospective study). Most children were reported as having a similar level as or fewer problems than was reported in the norm and retrospective studies. Reported problems decreased with time, but children who initially had more problems remained vulnerable during the year. Fathers and mothers highly agree in their perception of children's behavior, with the exception of adolescent daughters' behavior. Agreement between mothers and adolescent daughters was high, whereas agreement between fathers and adolescent sons and daughters, and mothers and adolescent sons was low to moderate. The outcomes suggest that most children do not experience problems shortly after the parent's diagnosis and were functioning over time on a level equal to or better than that of their peers. Differences in informant's perceptions appear and remain of interest.
