Morbidity and healthcare use among mothers of children with cancer: A population-based study

Background

The impact of a child's cancer diagnosis on subsequent maternal physical health is unclear.

Methods

We identified all Ontario children diagnosed less than 18 years with cancer between 1992 and 2017. Linkage to administrative databases identified mothers who were matched to population controls. We identified physical health conditions, acute healthcare use, and preventive healthcare use through validated algorithms using healthcare data, and compared them between exposed (child with cancer) and unexposed mothers. Predictors of health outcomes were assessed among exposed mothers.

Results

We identified 5311 exposed mothers and 19,516 matched unexposed mothers. For exposed mothers, median age at last follow-up was 48 years, (interquartile range: 42–53). Exposed mothers had an increased risk of cancer (hazard ratio [HR] 1.2, 95% confidence interval [95% CI]: 1.0–1.5, p = .03), but not of any other adverse physical outcomes or of increased acute healthcare use. Exposed mothers were more likely to receive influenza vaccinations (odds ratio 1.4, 95% CI: 1.3–1.5, p < .0001), and underwent cancer screening at the same rate as unexposed mothers. Among exposed mothers, bereavement was associated with a subsequent increased risk of cancer (HR 1.7, 95% CI: 1.2–2.5, p = .004) and death (HR 2.2, 95% CI: 1.2–4.1, p = .01).

Conclusion

Mothers of children with cancer are at increased risk of developing cancer, but not of other adverse physical health outcomes, and were equally or more likely to be adherent to preventive healthcare practices. Bereaved mothers were at increased risk of subsequent cancer and death. Interventions targeting specific subpopulations of mothers of children with cancer or focused on screening for specific cancers may be warranted.     

Worries and anxiety in parents of adult survivors of childhood cancer: A report from the Swiss Childhood Cancer Survivor Study-Parents

Objective

Having a child diagnosed with cancer is distressing for parents. We aimed to compare worries and anxiety in parents of adult childhood cancer survivors with parents of the Swiss general population (GP-parents), and to evaluate characteristics associated with worry in parents of survivors.

Methods

We conducted a nationwide, population-based study in parents of survivors (survivors aged ≥20 years at study, ≤16 years at diagnosis, >5 years post diagnosis) and GP-parents (≥1 child aged ≥20 years at study). We used the Worry and Anxiety Questionnaire (WAQ), and computed the WAQ total score (worries; possible range 0–80) and caseness for generalized anxiety disorder (anxiety), cognitive, somatic, and any criteria. We used multilevel, multivariable linear regression to identify characteristics associated with worries in parents of survivors.

Results

We included 787 parents of 513 survivors (41.0% fathers) and 478 GP-parents (42.3% fathers). Parents of survivors and GP-parents did not differ regarding worries (16.6 vs. 17.1, p = .977), anxiety (2.7% vs. 3.6%, p = .536), cognitive (p = .440), and somatic criteria (p = .067). Less parents of survivors met any criteria (17.7% vs. 24.0%, p = .039). Half of parents reported current cancer-related worries. Higher cancer-related worries were reported by mothers (β = 4.1; 95% CI: 2.0–6.2), parents with one child (β = 5.9; 95% CI: 2.0–9.7), currently experiencing disadvantages because of their child's former disease (β = 7.3; 95% CI: 4.0–10.6), or with support needs (β = 9.0; 95% CI: 3.9–14.2; p = .001).

Conclusions

It is encouraging that most parents of adult survivors report similar worries and anxiety as GP-parents, but cancer-related worries are still prevalent. Efforts should be made to empower parents to seek psycho-social support if required.     

Type of cancer and complementary and alternative medicine are determinant factors for the patient delay experienced by children with cancer: A study in West Java,Indonesia

Introduction

Most pediatric cancer patients in developing countries present at an advanced stage due to delayed diagnosis, being an important barrier to effective care. The objective of this study was to evaluate the associated factor of patient delay and explore significant parental practice-associated risk factor to patient delay.

Methods

This was a sequential mixed methodology, utilizing data from the Indonesian Pediatric Cancer Registry for clinical variables and completed interviews with parents using structured questionnaires to obtain their sociodemographic data. A binary logistic regression analysis model was fitted to identify factors associated with patient delay. Additional semi-structured interviews related to parental practice of using complementary and alternative medicine (CAM) were administered to 30 parents. Thematic framework analysis was performed on qualitative data to explore determinant factors of parental practice of using CAM.

Results

We interviewed 356 parents with children with cancer. The median patient delay was 14 days (interquartile range [IQR]: 6–46.5 days). The most extended delay was in patients with malignant bone tumors (median 66, IQR: 14–126). In multivariable logistic regression analysis, solid cancer (odds ratio [OR] = 5.22, 95% confidence interval [CI]: 2.79–9.77, p < .001) and use of CAM (OR = 1.86, 95% CI: 1.13–3.08, p = .015) were associated with patient delay. Qualitative interviews highlighted key issues relative to determinant parental factors using CAM, including vague initial childhood cancer symptoms, parental health-seeking behavior, CAM availability and accessibility, also barriers of healthcare facilities.

Conclusion

Type of cancer and use of CAM are essential factors that cause patient delay. It should be addressed in the future childhood cancer awareness and childhood cancer diagnosis pathway.     

Barriers to medication adherence in sickle cell disease: A comprehensive theory-based evaluation using the COM-B model

Background

Sickle cell disease (SCD) affects more than 100,000 Americans, with complications such as pain episodes and acute chest syndrome. Despite the efficacy of hydroxyurea in reducing these complications, adherence remains low. Study objectives were to examine barriers to hydroxyurea adherence, and to evaluate the relationship between barriers and their impact on adherence.

Methods

In this cross-sectional study, patients with SCD and their caregivers were enrolled if they were taking hydroxyurea. Study measures included demographics, self-report of adherence using visual analog scale (VAS), and the Disease Management and Barriers Interview (DMI)-SCD. The DMI-SCD was mapped to the Capability, Opportunity, Motivation, and Behavior (COM-B) model.

Results

Forty-eight caregivers (females 83%, median age 38 [34–43]) and 19 patients (male 53%, median age 15 [13.5–18]) participated. Using VAS, many patients (63%) reported low hydroxyurea adherence, while most caregivers (75%) reported high adherence. Caregivers endorsed barriers across multiple COM-B components, with physical opportunity (e.g., cost) and reflective motivation (e.g., SCD perceptions) being the most identified categories (48% and 42%), respectively. Patients’ most identified barriers included psychological capability (e.g., forgetfulness) and reflective motivation (84% and 68%), respectively. Patients’ and caregivers’ VAS scores negatively correlated with the number of barriers (r_s = –.53, p = .01; r_s = –.28, p = .05) and COM-B categories (r_s = –.51, p = .02; r_s = –.35, p = .01), respectively, suggesting lower adherence with more endorsed barriers.

Conclusions

Fewer barriers to hydroxyurea adherence were associated with higher adherence. Understanding barriers to adherence is essential to develop tailored interventions aimed at improving adherence.     

Predictors of Pediatric Frequent Emergency Department Use Among 7.6 million Pediatric Patients in New York

ObjectiveThis study examines the characteristics and factors associated with frequent emergency department (ED) utilization among the pediatric population.MethodsWe conducted a pooled cross-sectional secondary analysis using the Healthcare Cost and Utilization Project State Emergency and Inpatient Databases on ED visits to all hospitals in New York from 2011 to 2016 by patients aged 0 to 21. We used multivariable logistic and negative binomial regressions to investigate the predictors of multiple ED visits in the pediatric population.ResultsOverall, our study included 7.6 million pediatric patients who accounted for more than 12 million ED visits. Of those, 6.2% of patients were frequent ED users (≥4 visits/year), accounting for 20.8% of all ED visits (5.4 ED visits/year on average). The strongest predictors of frequent ED use were having at least one ED visit related to asthma (aOR = 8.37 [95% CI: 6.34–11.04]), mental health disorders (aOR = 9.67 [95% CI: 8.60–10.89]), or multiple comorbidities compared to none. Larger shares of ED visits for not-emergent conditions were also associated with frequent ED use (aOR = 6.63 [95% CI = 5.08–8.65]). Being covered by Medicaid compared to private (aOR = 0.45 [95% CI: 0.42–0.47]) or no insurance (aOR = 0.41 [95% CI: 0.38–0.44]) were further associated with frequent ED use. The results from the negative binomial regression yielded consistent findings.ConclusionsPediatric patients who exhibit increased ED use are more medically complex and have increased healthcare needs that are inextricably tied to social determinants of health. Better integrated health systems should emphasize connecting vulnerable patients to appropriate social and primary care services outside of emergency settings     

Outcome of patients with undifferentiated embryonal sarcoma of the liver treated according to European soft tissue sarcoma protocols

Background

To assess the outcomes of pediatric patients with undifferentiated embryonal sarcoma of the liver (UESL) and treatment including at least surgery and systemic chemotherapy.

Methods

This study included patients aged up to 21 years with a pathological diagnosis of UESL prospectively enrolled from 1995 to 2016 in three European trials focusing on the effects of surgical margins, preoperative chemotherapy, use of radiotherapy (RT), and chemotherapy.

Results

Out of 65 patients with a median age at diagnosis of 8.7 years (0.6–20.8), 15 had T2 tumors, and one had lymph node spread, 14 were Intergroup Rhabdomyosarcoma Study (IRS) I, nine IRS II, 38 IRS III, and four IRS IV. Twenty-eight upfront surgeries resulted in five operative spillages and 11 infiltrated surgical margins, whereas 37 delayed surgeries resulted in no spillages (p = .0119) and three infiltrated margins (p = .0238). All patients received chemotherapy, including anthracyclines in 47. RT was administered in 15 patients. With a median follow-up of 78.6 months, 5-year overall and event-free survivals (EFS) were 90.1% (95% confidence interval [CI]: 79.2–95.5) and 89.1% (95% CI: 78.4–94.6), respectively. Two out four local relapses had previous infiltrated margins and two out of three patients with metastatic relapses received reduced doses of alkylating agents. Infiltrated margins (p = .1607), T2 stage (p = .3870), use of RT (p = .8731), and anthracycline-based chemotherapy (p = .1181) were not correlated with EFS.

Conclusions

Multimodal therapy improved the outcome of UESL. Neoadjuvant chemotherapy for pediatric patients increases the probability of complete surgical resection. The role of anthracyclines and RT for localized disease remains unclear.     

Rates and predictors of visits to primary care physicians during and after treatment of childhood acute lymphoblastic leukemia: A population-based cohort study

Introduction

Patient re-engagement with primary care physicians (PCPs) after cancer treatment is essential to facilitate survivorship care and to meet non-oncology primary care needs. We identified rates and predictors of PCP visits both during and after treatment among a population-based cohort of children with acute lymphoblastic leukemia (ALL).

Methods

Children of age less than 18 years at ALL diagnosis in Ontario between 2002 and 2012 were linked to administrative data and matched to controls without cancer. PCPs at diagnosis were identified and PCP visit rates during treatment compared between patients and controls. Post-treatment PCP visit rates were also calculated. Predictors included demographic-, disease-, and PCP-related variables.

Results

A total of 743/793 (94%) patients and 3112/3947 (79%) controls had a PCP at diagnosis. Almost half of patients (361/743, 45%) did not visit their PCP during treatment. Visit rate during treatment was 0.64 per person per year (PPPY) versus 1.4 PPPY among controls (adjusted rate ratio [aRR] 0.47, 95th confidence interval [95CI]: 0.40–0.54; p < .0001). No disease- or PCP-related factors were associated with visit rates. Total 711 patients completed frontline therapy; 287 (40.4%) did not have a PCP visit after treatment. Nonetheless, survivors overall visited PCPs post treatment more often than controls (aRR 1.4, 95CI: 1.2–1.6; p < .0001). Survivors who saw their PCP during treatment had post-treatment visit rates twice that of other survivors (aRR 2.0, 95CI: 1.6–2.5; p < .0001).

Conclusions

Only a portion of children with ALL see their PCPs during treatment and return to PCP care following treatment completion. Post-treatment engagement with PCPs may be improved by PCP involvement during ALL treatment.     

Facial deformation following treatment for pediatric head and neck rhabdomyosarcoma; the difference between treatment modalities. Results of a trans-Atlantic,multicenter cross-sectional cohort study

Background

The four different local therapy strategies used for head and neck rhabdomyosarcoma (HNRMS) include proton therapy (PT), photon therapy (RT), surgery with radiotherapy (Paris-method), and surgery with brachytherapy (AMORE). Local control and survival is comparable; however, the impact of these different treatments on facial deformation is still poorly understood. This study aims to quantify facial deformation and investigates the differences in facial deformation between treatment modalities.

Methods

Across four European and North American institutions, HNRMS survivors treated between 1990 and 2017, more than 2 years post treatment, had a 3D photograph taken. Using dense surface modeling, we computed facial signatures for each survivor to show facial deformation relative to 35 age–sex–ethnicity-matched controls. Additionally, we computed individual facial asymmetry.

Findings

A total of 173 HNRMS survivors were included, survivors showed significantly reduced facial growth (p < .001) compared to healthy controls. Partitioned by tumor site, there was reduced facial growth in survivors with nonparameningeal primaries (p = .002), and parameningeal primaries (p ≤.001), but not for orbital primaries (p = .080) All patients were significantly more asymmetric than healthy controls, independent of treatment modality (p ≤ .001). There was significantly more facial deformation in orbital patients when comparing RT to AMORE (p = .046). In survivors with a parameningeal tumor, there was significantly less facial deformation in PT when compared to RT (p = .009) and Paris-method (p = .007).

Interpretation

When selecting optimal treatment, musculoskeletal facial outcomes are an expected difference between treatment options. These anticipated differences are currently based on clinicians’ bias, expertise, and experience. These data supplement clinician judgment with an objective analysis highlighting the impact of patient age and tumor site between existing treatment options.     

Total serum bilirubin levels during the first 2 days of life and subsequent neonatal morbidity in very low birth weight infants: a retrospective review

To determine the relationship between total serum bilirubin (TSB) during the first 2 days of life and subsequent neonatal morbidity in very low birth weight (VLBW, less than 1500 g) infants. We performed a prospective study of 582 VLBW infants born between July 1, 2005 and December 31, 2009. TSB was measured in umbilical cord blood (UCB), at 24 and 48 h after birth. Demographic and clinical characteristics of infants in hospital were recorded. The interaction between TSB variables during the first 48 h of life and subsequent neonatal morbidity were assessed in logistic regression analyses adjusted for multiple risk factors. It was found that TSB in UCB was in a negative correlation with occurrence of respiratory distress syndrome (RDS) [OR 0.626, 95% confidence interval (95% CI): 0.446–0.879, p = 0.007], and there was also a negative correlation between TSB in UCB and occurrence of intraventricular hemorrhage (IVH) [OR 0.695, 95% CI 0.826–0.981, p = 0.020]. However, TSB in UCB positively correlated with hyperbilirubinemia [OR 2.471, 95% CI 1.326–3.551, p = 0.012], and TSB at 24 h after birth was also in a positive correlation with early onset sepsis (EOS) [OR 1.299, 95% CI 1.067–1.582, p = 0.011]. VLBW infants with low TSB levels in UCB were more likely to develop RDS and IVH, and those with low TSB levels in UCB were less likely to develop hyperbilirubinemia. Infants with high TSB levels at 24 h after birth were more likely to develop EOS. The protective effect of raised TSB in UCB with respect to RDS and IVH warrants further investigation.     

Factors associated with syndemic anemia and stunting among children in Myanmar: A cross-sectional study from a positive deviance approach

BackgroundAnemia and stunting in children are detrimental to the prospects of a normal, healthy upbringing. Having similar risk factors and serious consequences, the syndemic aspect of these two ailments is mostly underrated, and positive deviant (PD) factors that ensure non-anemic status in stunted children have not been studied to date.MethodsThis study aimed to identify PD factors that have potential to prevent syndemic anemia among stunted children aged 6–59 months in Myanmar. This was a cross-sectional secondary analysis of the Myanmar Demographic and Health Survey (DHS) data conducted in 2016, applying the PD concept, where children who were stunted without anemia were considered as PDs.ResultsAmong 1248 stunted children, those who had the syndemic condition were compared with their PD peers in terms of maternal characteristics as well as socioeconomic and health-related factors. Multivariable logistic regression analyses were used to identify the determinants of syndemic state. The results showed that three out of every five stunted children were anemic. The syndemic risk was decreased among children of maternal age groups 20–34 years and 35–44 years: [aOR] = 0.19, 95% CI = 0.05–0.69; p = 0.012, and aOR = 0.19, 95% CI = 0.05–0.75; p = 0.018, respectively. Moderately stunted children (aOR = 0.53, 95% CI = 0.34–0.81; p = 0.004) and children who were not currently breastfed (aOR = 1.56, 95% CI = 1.01–2.41; p = 0.044) were less likely to develop the syndemic condition.ConclusionMaternal age, stunting severity, breastfeeding duration, and maternal anemic status are strong predictors in determining hemoglobin concentrations among stunted children. This study suggests that nutritional interventions targeting PD factors could represent syndemic action in improving child health.     

Extracranial germ cell tumours in children and adolescents: Results from the French TGM13 protocol

Background

Chemotherapy for non-seminomatous germ cell tumours (NSGCT) exposes to dose-dependent toxicities. The TGM13-NS protocol (EudraCT 2013-004039-60) aimed to decrease the chemotherapy burden compared to the previous TGM95 protocol while maintaining the 5-year event-free survival (EFS) at 80% or more.

Procedure

Patients less than 19 years of age with disseminated NSGCT were enrolled (May 2014 to May 2019) and stratified into four groups: two intermediate-risk (IR: localised tumour with low tumour markers [TM]) groups treated with VBP (vinblastine–bleomycin–cisplatin): three courses for IR1 (ovarian tumour any age/testis tumour less than or equal to 10 years) and four courses for IR2 (extragonadal tumour 10 years or less) groups, and two high-risk (HR: metastatic and/or high TM) groups treated with etoposide–cisplatin and either ifosfamide (VIP) or bleomycin (BEP): three courses for HR1 (ovarian tumour any age/testis tumour less than or equal to 10 years and low TM/testis tumour more than 10 years and very low TM) groups and four courses for HR2 (remainder) groups.

Results

One hundred fifteen patients were included: median age of 12.8 years (0.4–18.9); tumour sites: 44 ovaries, 37 testes and 34 extragonadal. The 5-year EFS and overall survival (OS) were 87% (95% CI: 80–92) and 95% (89–98), respectively (median follow-up: 3.5 years, range: 0.2–5.9), similar to those of the TGM95 protocol (5-year EFS 89% (84–93), 5-year OS 93% (89–95), p = .561). The 5-year EFS were 93% (95% CI: 80–98), 88% (71–95) and 79% (62–90) for ovarian, testicular and extragonadal tumours, respectively. The 5-year EFS varied (p = .02) according to the risk groups: 90% (66–97), 64% (30–85), 95% (72–99) and 87% (74–94) for IR1, IR2, HR1 and HR2, respectively. TM decline adjusted to tumour site, and alpha-fetoprotein (AFP) level revealed a prognostic impact of time to normalisation on EFS: HR = 1.03 (1.003–1.007).

Conclusion

Risk-adapted and globally decreased chemotherapy burden maintains excellent outcomes, exclusive of the IR2 group, which warrants more intensive chemotherapy.     

Interdisciplinary care of pediatric oncology patients: A survey of clinicians in Central America and the Caribbean

Background

Quality cancer care depends on interdisciplinary communication. This study explored the communication practices of interdisciplinary clinicians, the types of healthcare services for which they engage in interdisciplinary collaboration, and the association between interdisciplinary care and perceived quality of care, as well as job satisfaction.

Methods

We conducted a survey of interdisciplinary clinicians from cancer centers in Guatemala, Honduras, Panama, El Salvador, and Haiti. The survey included 68 items including previously validated tools and novel questions.

Results

Total 174 interdisciplinary clinicians completed the survey: nurses (n = 60), medical subspecialists (n = 35), oncologists (n = 22), psychosocial providers (n = 20), surgeons (n = 12), pathologists (n = 9), radiologists (n = 9), and radiation oncologists (n = 5). Oncologists reported daily communication with nurses (95%) and other oncologists (91%). While 90% of nurses reported daily communication with other nurses, only 66% reported daily communication with oncologists, and more than 50% of nurses reported never talking to pathologists, radiologists, radiation oncologists, or surgeons. Most clinicians described interdisciplinary establishment of cancer treatment goals and prognosis (84%), patient preferences (81%), and determination of first treatment modality (80%). Clinicians who described more interdisciplinary collaboration had higher job satisfaction (p = .04) and perceived a higher level of overall quality of care (p = .004).

Conclusions

Clinicians in these limited resource settings describe strong interdisciplinary collaboration contributing to higher job satisfaction and perceived quality of care. However, nurses in these settings reported more limited interdisciplinary communication and care. Additional studies are necessary to further define clinical roles on interdisciplinary care teams and their associations with patient outcomes.     

Feeding behaviors during home‐based treatment of moderate acute malnutrition using corn‐soy blends or lipid‐based nutrient supplements

Feeding behaviors have an important impact on children's nutritional status and are essential to consider when implementing nutrition programs. The objective of this study was to explore and compare feeding behaviors related to supplementary feeding with corn‐soy blends (CSB) and lipid‐based nutrient supplements (LNS) based on best practice feeding behaviors. The study was conducted as part of a randomized controlled trial assessing the effectiveness of new formulations of CSB and LNS and comprised 1,546 children from 6 to 23 months. The study included a mixed methods approach using questionnaires, focus group discussions and home visits and interviews with a subsample of 20 caretakers of trial participants. We found that LNS, compared to CSB, were more likely to be mixed into other foods (OR [95% CI] 1.7 [1.3–2.2], p = <.001), served with a meal (OR [95% CI] 1.6 [1.1–2.3], p = <.018)or between meals (OR [95% CI] 1.5 [1.1–1.9], p = <.005), and fed using an encouraging feeding style (mean difference in percentage points [95% CI] 23% [6%:40%], p = .01). CSB were more likely to be fed using a forced feeding style (mean difference in percentage points [95% CI] 18% [3%:33%], p = .02) and were often observed to be served unprepared. The main differences in feeding behaviors between the two diet groups were linked to how and when supplements were served. Educational instructions should therefore be adapted according to the supplement provided; when providing CSB, efforts should be made to promote an encouraging feeding style, and emphasis should be made to ensure preparations are made according to recommendations.     

The prognostic value of IKZF1plus in B-cell progenitor acute lymphoblastic leukemia: Results from the EORTC 58951 trial

Background

IKZF1 gene deletion is an indicator of poor prognosis in childhood B-cell precursor acute lymphoblastic leukemia (BCP-ALL). The AEIOP/BFM group proposed that the prognostic strength of IKZF1 deletion could be remarkably improved by taking into account additional genetic deletions and reported that among patients with an IKZF1 deletion those with deletions in CDKN2A/2B, PAX5, or PAR1 in the absence of ERG deletion, grouped as IKZF1^plus, had the worst outcome.

Procedure

Between 1998 and 2008, 1636 patients under 18 years of age with previously untreated BCP-ALL were registered in the EORTC 58951 trial. Those with multiplex ligation-dependent probe amplification data were included in this analysis. Unadjusted and adjusted Cox model was used to investigate the additional prognostic value of IKZF1^plus.

Results

Among 1200 patients included in the analysis, 1039 (87%) had no IKZF1 deletion (IKZF1^WT), 87 (7%) had an IKZF1 deletion but not IKZF1^plus (IKZF1^del) and 74 (6%) had IKZF1^plus. In the unadjusted analysis, both patients with IKZF1^del (hazard ratio [HR] = 2.10, 95% confidence interval [CI]: 1.34–3.31) and IKZF1^plus (HR = 3.07, 95% CI: 2.01–4.67) had a shorter event-free survival compared with IKZF1^WT. However, although the IKZF1^plus status was associated with patients’ characteristics indicating poor prognosis, the difference between IKZF1^plus and IKZF1^del was not statistically significant (HR = 1.46, 95% CI: 0.83–2.57, p = .19). The results of the adjusted analysis were similar to the unadjusted analysis.

Conclusions

In patients with BCP-ALL from the EORTC 58951 trial, the improvement of the prognostic importance of IKZF1 by considering IKZF1^plus was not statistically significant.     

Impact of ovarian transposition before pelvic irradiation on ovarian function among long‐term survivors of childhood Hodgkin lymphoma: A report from the St. Jude Lifetime Cohort Study

1 Background

We reviewed the effect of ovarian transposition (OT) on ovarian function among long‐term survivors of childhood Hodgkin lymphoma (HL) treated with pelvic radiotherapy.

2 Procedure

Female participants (age 18+ years) with HL in the St. Jude Lifetime Cohort Study (SJLIFE) were clinically evaluated for premature ovarian insufficiency (POI) 10 or more years after pelvic radiotherapy. Reproductive history including age at menopause and pregnancy/live births was available on all patients.

3 Results

Of 127 eligible females with HL, 90 (80%) participated in SJLIFE, including 49 who underwent OT before pelvic radiotherapy. Median age at STLIFE evaluation was 38 years (range 25–60). In a multiple regression adjusted for age at diagnosis, pelvic radiotherapy doses > 1,500 cGy (hazard ratio [HR] = 25.2, 95% confidence interval [CI] = 3.1–207.3; P = 0.0027) and cumulative cyclophosphamide equivalent doses of alkylating agents > 12,000 mg/m² (HR = 11.2, 95% CI = 3.4–36.8; P < 0.0001) were significantly associated with POI. There was no significant association between OT and occurrence of POI (HR = 0.6, 95% CI = 0.2–1.9; P = 0.41).

4 Conclusions

OT did not appear to modify risk of POI in this historic cohort of long‐term survivors of HL treated with gonadotoxic therapy. Modern fertility preservation modalities, such as mature oocyte cryopreservation, should be offered to at‐risk patients whenever feasible.     

Maternal migraine and risk of pediatric cancers

Background

Maternal migraine has been linked to adverse birth outcomes including low birth weight and preterm birth, as well as congenital anomalies in offspring. It has been speculated that this may be due to the use of medications in pregnancy, but lifestyle, genetic, hormonal, and neurochemical factors could also play a role. There is evidence for varying cancer incidences among adults with migraine. Here, we utilized data from national registries in Denmark to examine associations between maternal diagnoses of migraine and risk for cancer in offspring.

Methods

We linked several national registries in Denmark to identify cases from the Cancer Registry among children less than 20 years (diagnoses 1996–2016) and controls from the Central Population Register, matched to cases by birth year and sex (25:1 matching rate). Migraine diagnoses were identified from the National Patient Register using International Classification of Diseases, versions 8 and 10 codes and migraine-specific acute or prophylactic treatment recorded in the National Pharmaceutical Register. We used logistic regression to estimate the risk of childhood cancers associated with maternal migraine.

Results

Maternal migraine was positively associated with risk for non-Hodgkin lymphoma (odds ratio [OR] = 1.70, 95% confidence interval [CI]: 1.01–2.86), central nervous system tumors ([OR = 1.31, 95% CI: 1.02–1.68], particularly glioma [OR = 1.64, 95% CI: 1.12–2.40]), neuroblastoma (OR = 1.75, 95% CI: 1.00–3.08), and osteosarcoma (OR = 2.60, 95% CI: 1.18–5.76).

Conclusions

Associations with maternal migraine were observed for several childhood cancers, including neuronal tumors. Our findings raise questions about the role of lifestyle factors, sex hormones, genetic, and neurochemical factors in the relationship between migraine and childhood cancers.     

The changing clinical pattern of endemic Burkitt lymphoma in Western Africa: Experience from a tertiary center in Ghana

1 Background

Burkitt lymphoma (BL) is the most common childhood cancer in Ghana, where the endemic variant is the predominant subtype and historically presents as a highly chemo‐sensitive jaw tumor. This study aimed to update the current epidemiological characteristics of childhood BL in our institution.

2 Procedure

Patient data for all children diagnosed with BL and seen at Korle Bu Teaching Hospital between January 2007 and December 2012 were retrospectively analyzed.

3 Results

BL was diagnosed in 173 children (<13 years) during the study period, with the abdomen as the most common tumor site (46%) followed by the jaw (31%). Abdominal tumors were associated with advanced/disseminated disease (P = 0.002), and were more likely to occur in females irrespective of tumor stage (relative risk = 1.56 [95% CI; 1.1–12.3]). Twenty‐five percent (43/173) of the study cohort died and mortality was influenced by increasing age (P = 0.02) and advanced disease (P = 0.03). Treatment delay was experienced by nine in ten patients primarily due to familial financial constraint (75%). Treatment abandonment was observed as a first event in 94% of patients and two thirds of children in the study were eventually lost to follow‐up.

4 Conclusion

The predominance of primary abdominal tumors in our study cohort may indicate a changing epidemiological pattern of BL in Ghana. High rates of treatment delay and abandonment were evident and are likely to be contributing factors to the poor childhood cancer survival outcomes seen in resource‐limited countries in Africa.     

The Impact of Prenatal Diagnosis of Complex Congenital Heart Disease on Neonatal Outcomes

Prenatal diagnosis of congenital heart disease (CHD) is increasingly common. However, the current impact of prenatal diagnosis on neonatal outcomes is unclear. Between January 2004 and January 2008, a retrospective chart review of infants who underwent surgical repair of CHD before discharge at our institution was conducted. Obstetric and perioperative variables were recorded. Of 439 neonates, 294 (67%) were diagnosed prenatally (PREdx). Infants with PREdx had a lower mean birth weight (3.0 ± 0.6 vs. 3.1 ± 0.6 kg, p = 0.002) and gestational age (37.9 ± 2.1 vs. 38.6 ± 2.4 wk, p < 0.001) than those with postnatal diagnosis (POSTdx). Severe lesions were more likely to be PREdx: Neonates with single-ventricle (SV) physiology (n = 130 patients [31.2%]) had increased odds of PREdx (n = 113/130, odds ratio [OR] 4.7; 95% confidence interval [CI] 2.7–8.2, p < 0.001). PREdx was associated with decreased preoperative intubation (OR 0.62; 95% CI 0.42–0.95, p = 0.033), administration of antibiotics (OR 0.23; 95% CI 0.15–0.36, p < 0.001), cardiac catheterization (OR 0.54; 95% CI 0.34–0.85, p = 0.01), and emergency surgery (OR 0.18; 95% CI 0.06–0.5, p < 0.001) compared with POSTdx infants. There was no difference in APGAR scores, preoperative pH, day of life of surgery, operative complications, hospital length of stay, or overall mortality in the PREdx versus POSTdx groups, even when controlling for lesion severity. PREdx was not independently associated with neonatal mortality, despite having included more severe cardiac lesions. PREdx was significantly associated with decreased neonatal morbidity in terms of decreased use of preoperative ventilator, administration of antibiotics, cardiac catheterization, and emergency surgery.
