Abstract
INTRODUCTION Research on childhood cancer survivor offspring has been limited to genetic disease occurrence, malformations or non-hereditary cancers. However, previous surveys indicated that survivors harbor fears about their (prospective) children's overall health. Our Multicenter Offspring Study examined extensive health aspects in children born to survivors and their siblings providing comprehensive information to be used in patient counseling to elucidate and alleviate existing concerns. METHODS Using a specifically designed questionnaire, childhood cancer survivors and their siblings were surveyed on their offspring's health (Supplementary material). Recruitment strategies depended on local infrastructures and standards of participating centers, including registry-based and direct approaches. Group differences were tested non-parametrically and effect sizes were calculated. RESULTS In total, 1126 survivors reported on 1780 offspring and 271 siblings reported on 441 offspring. Response rates ranged from 32.1% (Czech Republic) to 85.0% (Austria). Respondents were more likely to be female (p = .007), older at time of survey (p < .001), diagnosed 1980-1999 (p < .001) and treated with chemotherapy (p < .001). Compared to siblings, survivors were younger at time of survey (35 years vs. 39 years, p < .001) and at first birth (29 years vs. 30 years, p < .001). Survivor and sibling offspring only differed in terms of age at survey (6.3 years vs. 8.9 years, p < .001). CONCLUSION The Multicenter Offspring Study investigates a wide variety of health aspects in offspring born to survivors and their siblings in five European countries. Our study cohorts form a solid basis for future analyses; yet, certain limitations, due to differences in approach among participating centers, must be considered when interpreting findings.

Psychooncology 2021; 30:1866-1875. [PMID: 34156134 DOI: 10.1002/pon.5752] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Revised: 05/17/2021] [Accepted: 06/15/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Rising childhood cancer survival rates have increased the importance of health-related quality of life (HRQL) assessment. While survivors show comparable HRQL to peers, concerns that cancer treatment could impact the health of prospective children were reported. No previous publications address HRQL of childhood cancer survivor offspring. METHODS We assessed survivor offspring HRQL using the parental KINDL questionnaire. Matched-pair analysis was conducted with data from the general population (KiGGS study) using age, gender and education (1:1, n = 1206 cases). Multivariate analyses were conducted to detect the influence of parental diagnose and treatment on offspring HRQL. RESULTS Overall, within KINDL dimensions, survivors reported comparable to higher HRQL for their children than the general population. Survivor parents reported significantly (p < 0.001) higher psychological (86.7% vs. 83.0%, Cohen's d = 0.3) and self-esteem (79.1% vs. 73.3%, Cohen's d = 0.5) well-being scores for younger children (3-6-year-olds). As time since diagnosis increased, parents reported higher well-being scores. Accordingly, recently diagnosed survivors reported significantly lower psychological well-being scores (p = 0.28; OR = 0.457; 95% CI = 0.228-0.918) for their children. With increasing age, average HRQL scores decreased in both cohorts; yet, this drop was less pronounced for survivor offspring. The biggest difference between age groups (7-10- vs. 14-17-year-olds) was found for school-specific well-being (6.2-point drop in survivor offspring vs. 18.2-point drop in KiGGS offspring). CONCLUSION Comparable to higher parentally assessed HRQL was reported for survivor offspring compared to peers. These findings are reassuring and consistent with self-reported HRQL in childhood cancer survivors. Type of parental cancer diagnosis and treatment showed no negative impact on offspring HRQL.

Health outcomes in offspring born to survivors of childhood cancers following assisted reproductive technologies. J Cancer Surviv 2020; 15:259-272. [PMID: 32844376 PMCID: PMC7966626 DOI: 10.1007/s11764-020-00929-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Accepted: 08/15/2020] [Indexed: 10/27/2022]
Abstract
PURPOSE An increasing number of childhood cancer survivors are using assisted reproductive technologies (ART) to overcome treatment-related fertility impairment. We report perinatal and health outcomes of offspring born to survivors following ART. METHODS The FeCt Multicenter Offspring Study surveyed the health of offspring of childhood cancer survivors. Health outcomes in offspring born to survivors following ART (n = 57, 4.6%) or after spontaneous conception (n = 1182) were assessed in the German cohort (n = 1239) using bivariate analysis. Findings were put into the context of the general German population by health outcome assessment in 1:1 matched-pair analysis (n = 2478). RESULTS Nearly twice the survivors used ART compared with numbers reported for the German general population (4.6% vs. 2.6%). Successful pregnancies were achieved after a median of two cycles, mainly using non-cryopreserved oocytes/sperm. Multiple sibling births (p < 0.001, 28.1% vs. 3.0%) and low birth weight (p = 0.008; OR = 2.659, 95% CI = 1.258-5.621) occurred significantly more often in offspring born to survivors who utilized ART than spontaneously conceived children, whereas similar percentages were born preterm or too small for their gestational age. ART did not increase the prevalence of childhood cancer or congenital malformations in offspring born to survivors. CONCLUSION ART use by childhood cancer survivors was successful with both fresh and cryopreserved oocytes/sperm, and did not influence perinatal health or health outcomes when known confounders were taken into account. IMPLICATIONS FOR CANCER SURVIVORS Oncofertility is an important component of patient care. Our study implicates that the utilization of ART by adult survivors of childhood cancer does not put offspring at additional risk for adverse perinatal or health outcomes.
