Stillbirth After Adolescent and Young Adult Cancer: A Population-Based Study.

ABSTRACT:

Background

Gonadotoxic effects of cancer treatment may increase risk of adverse birth outcomes in adolescent and young adult (AYA, aged 15-39 years) women diagnosed with cancer. We estimated risk of stillbirth (fetal death of gestational age ≥20 weeks or weighing ≥350 grams) in a population-based sample of AYA women.

Methods

AYA women diagnosed with cancer between January 1, 1995, and December 31, 2015, were identified using the Texas Cancer Registry and linked to live birth and fetal death certificates through December 31, 2016. Among AYA women, cumulative incidence of stillbirth was estimated by gestational age, and Poisson regression models identified factors associated with stillbirth. Standardized fetal mortality ratios (SMR) compared the observed fetal mortality rate in AYA women with the expected fetal mortality rate in the general population.

Results

A total of 11 628 live births and 68 stillbirths occurred to 8402 AYA women after diagnosis. Cumulative incidence of stillbirth in AYA women was 0.70% (95% confidence interval [CI] = 0.51% to 0.96%) at 40 weeks of gestation. Risk of stillbirth was higher among Hispanic (risk ratio [RR] = 2.64, 95% CI = 1.29 to 5.41) and non-Hispanic Black (RR = 4.13, 95% CI = 1.68 to 10.16) women compared with non-Hispanic White women; there was no association with receipt of chemotherapy or time since diagnosis. Age- and race and ethnicity-adjusted fetal mortality rate in AYA women was similar to the general population (SMR = 0.99, 95% CI = 0.77 to 1.26).

Conclusions

AYA women may be counseled that overall risk of stillbirth is low, and for most, cancer does not appear to confer additional risk.

Project description:BackgroundAs the survival rates of cancer patients continue to increase, most cancer patients now die of non-cancer causes. Several studies have been showing elevated suicide rates among patients with cancer. However, no large-scale study has thoroughly assessed the risk of suicide among adolescent and young adult (AYA) patients with cancer. This study was conducted to characterize suicide mortality among AYA patients in the US and identify risk factors associated with a higher risk of suicide.MethodsPatients aged 15-39 years were residents of the US served by the Surveillance, Epidemiology, and End Results (SEER) program, who were diagnosed with cancers from 1973 to 2015.ResultsWe report that 981 of the 572,500 AYA patients with cancer committed suicide, for an age-, sex-, and race-adjusted suicide rate of 17.68/100,000 person-years. The rate of suicide was 14.33/100,000 person-years in the corresponding general population, giving a standardized mortality ratio (SMR) of 1.234 [95% confidence interval (CI) 1.159-1.313]. Higher suicide rates were associated with male sex, white race, unmarried state, distant tumor stage, and single primary tumor. AYA patients with otorhinolaryngologic, gonad, stomach, soft tissue, and nasopharyngeal cancer were at the greatest risk of suicide compared with those with other types of cancer. In older patients (≥ 40 years), the risk was highest in those with lung, stomach, oral cavity and pharynx, larynx, and bone malignancies. SMRs were highest in the first 5 years after diagnosis for most types of cancer.ConclusionAYA patients with cancer in the US have over 20% higher the incidence of suicide of the general population, and most suicides occurred in the first 5 years following diagnosis. Suicide rates vary among patients with cancers of different anatomic sites. Further examination of the psychological experience of these young patients with cancer, particularly that of those with certain types of cancer, is warranted.

Project description:BackgroundFew studies have investigated the risks of subsequent primary neoplasms after adolescent and young adult (AYA) cancer. We investigated the risks of specific subsequent primary neoplasms after each of 16 types of AYA cancer.MethodsThe Teenage and Young Adult Cancer Survivor Study is a population-based cohort of 200 945 survivors of cancer diagnosed when aged 15-39 years in England and Wales from Jan 1, 1971, to Dec 31, 2006. The cohort was established using cancer registrations from the Office for National Statistics and the Welsh Cancer registry. Follow-up was from 5-year survival until the first occurrence of death, emigration, or study end date (Dec 31, 2012). In this analysis, we focus on the risk of specific subsequent primary neoplasms after 16 types of AYA cancer: breast; cervical; testicular; Hodgkin lymphoma (female); Hodgkin lymphoma (male); melanoma; CNS (intracranial); colorectal; non-Hodgkin lymphoma; thyroid; soft-tissue sarcoma; ovarian; bladder; other female genital; leukaemia; and head and neck cancer. We report absolute excess risks (AERs; per 10 000 person-years) and cumulative incidence of specific types of subsequent primary neoplasm after each type of AYA cancer.FindingsDuring the 2 631 326 person-years of follow-up (median follow-up 16·8 years, IQR 10·5-25·2), 12 321 subsequent primary neoplasms were diagnosed in 11 565 survivors, most frequently among survivors of breast cancer, cervical cancer, testicular cancer, and Hodgkin lymphoma. AERs of any subsequent primary neoplasms were 19·5 per 10 000 person-years (95% CI 17·4-21·5) in survivors of breast cancer, 10·2 (8·0-12·4) in survivors of cervical cancer, 18·9 (16·6-21·1) in survivors of testicular cancer, 55·7 (50·4-61·1) in female survivors of Hodgkin lymphoma, and 29·9 (26·3-33·6) in male survivors of Hodgkin lymphoma. The cumulative incidence of all subsequent primary neoplasms 35 years after diagnosis was 11·9% (95% CI 11·3-12·6) in survivors of breast cancer, 15·8% (14·8-16·7) in survivors of cervical cancer, 20·2% (18·9-21·5) in survivors of testicular cancer, 26·6% (24·7-28·6) in female survivors of Hodgkin lymphoma, and 16·5% (15·2-18·0) in male survivors of Hodgkin lymphoma. In patients who had survived at least 30 years from diagnosis of cervical cancer, testicular cancer, Hodgkin lymphoma in women, breast cancer, and Hodgkin lymphoma in men, we identified a small number of specific subsequent primary neoplasms that account for 82%, 61%, 58%, 45%, and 41% of the total excess number of neoplasms, respectively. Lung cancer accounted for a notable proportion of the excess number of neoplasms across all AYA groups investigated.InterpretationOur finding that a small number of specific subsequent primary neoplasms account for a large percentage of the total excess number of neoplasms in long-term survivors of cervical, breast, and testicular cancer, and Hodgkin lymphoma provides an evidence base to inform priorities for clinical long-term follow-up. The prominence of lung cancer after each of these AYA cancers indicates the need for further work aimed at preventing and reducing the burden of this cancer in future survivors of AYA cancer.FundingCancer Research UK, National Institute for Health Research, Academy of Medical Sciences, and Children with Cancer UK.

Project description:BackgroundThe fertility of adolescent and young adult (AYA) patients with cancer can be threatened by treatments, but to the authors' knowledge little is known regarding the extent to which providers discuss this with patients or recommend fertility preservation, or the patient and physician characteristics associated with these interactions.MethodsQuestionnaires from 459 AYA patients with cancer who were diagnosed between 2007 and 2008 and recruited through 7 US population-based cancer registries were analyzed using sex-specific multivariable models. The authors assessed characteristics associated with not discussing therapy effects on fertility or fertility preservation options, and not making fertility preservation arrangements.ResultsMales without a medical oncologist were more likely not to be told that therapy might affect fertility than those with a medical oncologist (male odds ratio [OR], 2.28; 95% confidence interval [95% CI], 1.03-5.00). Individuals without insurance (male OR, 2.91 [95% CI, 1.41-5.91] and female OR, 5.46 [95% CI, 1.59-18.72]); those raising children aged <18 years; and, among males only, those who received treatment posing no or a low fertility risk (OR, 3.39; 95% CI, 1.60-7.16) were more likely not to discuss fertility preservation with providers. Finally, among males, those without a college degree (OR, 1.98; 95% CI, 1.00-3.97), lacking private insurance (OR, 2.97; 95% CI, 1.16-7.63), and raising children aged <18 years (OR, 3.53; 95% CI, 1.63-7.65) were more likely to not make fertility preservation arrangements; too few females had made fertility preservation arrangements for similar analyses to be performed.ConclusionsDiscussion and action surrounding fertility preservation for AYA patients with cancer are associated with medical factors, patient socioeconomic data, and child-rearing status. These results highlight the need for insurance coverage for fertility preservation and increased awareness of fertility preservation options.

Project description:Survivors of childhood, adolescent, and young adult cancer are known to be at risk of late effects of their disease and its treatment. Most population-based studies of cancer survivors have reported on second primary cancers and mortality. The aim of this study was to research acute and psychiatric hospital admission rates and length of stay in 5-year survivors of cancer diagnosed before the age of 25 years.This was a population-based retrospective cohort study using linked national cancer registry, acute hospital discharge, psychiatric hospital, and mortality records. The study population consisted of 5229 individuals who were diagnosed with cancer before the age of 25 years between 1981 and 2003, and who survived at least 5 years after the date of diagnosis of their primary cancer. Indirect standardisation for age and sex was used to calculate standardised bed days and hospitalisation ratios (SBDR and SHR) for both acute and psychiatric hospital admissions, and absolute excess risks (AERs) compared with the general Scottish population.Five-year survivors of cancer, diagnosed before the age of 25 years, are at increased risk of admission to acute hospitals (SHR 2.8; 95% confidence interval 2.7-2.9) and of spending more time in hospital (SBDR 3.7; 3.6-3.7). Corresponding AERs were 6.4 (6.0-6.6) admissions and 64.8 (64.4-66.9) bed days per 100 cancer survivors per year. In contrast, 5-year survivors were not at higher risk of admission to psychiatric hospital (SHR 0.9; 0.8-1.2), and they spent significantly less time as psychiatric in-patients (SBDR 0.4; 0.4-0.4) compared with the whole population.Using routinely collected linked records, our population-based study has demonstrated increased rates of hospitalisation in 5-year survivors of cancer diagnosed before the age of 25 years. Long-term clinical follow-up of survivors of cancer in this age group should focus on the prevention and treatment of the late effects of cancer in those patients at highest risk of hospitalisation.
