Purpose: Many patients with cancer do not gain Medicaid coverage until a cancer diagnosis, which can reduce access to early cancer detection and timely treatment, potentially driving inferior survival. Little is known about whether continuous Medicaid coverage prediagnosis through postdiagnosis ( gaining Medicaid at/after diagnosis) provides survival benefits for pediatric/adolescent oncology patients.

Materials And Methods: We identified patients newly diagnosed with cancer at age 21 years or younger in a large pediatric health system between 2007 and 2016.

Background: Childhood cancer survivors need regular, long-term survivor care. The Children's Oncology Group (COG) recommends that pediatric patients receive ongoing, evidence-based surveillance for late effects, beginning 2 years after the completion of cancer therapy. However, at least a third of survivors are not engaging in long-term survivorship care.

The extent to which heavy metal chemotherapy results in treatment-related ovarian damage is controversial. Anti-Mullerian hormone (AMH) levels measured more than 1 year after cancer therapy completion were abstracted from the medical records of 39 female survivors of childhood cancer aged 11 years and older, whose only gonadotoxic exposure was heavy metal chemotherapy. One-fifth of survivors who received cisplatin had AMH levels indicative of diminished ovarian reserve at last measurement.

Allogeneic hematopoietic cell therapy (HCT) is an established cure for sickle cell disease (SCD); however, HCT conditioning regimens are known to be gonadotoxic. Anti-mullerian hormone (AMH) measures ovarian reserve, and follicle-stimulating hormone (FSH) defines premature ovarian insufficiency (POI) at values >40 mIU/mL in pubertal females. The present study was conducted to assess ovarian reserve and function before and after transplantation in pediatric and adolescent females with SCD treated with allogeneic HCT between January 2015 and June 2020 at Children's Healthcare of Atlanta.

Background: Cancer survivors who received gonadotoxic treatment are at-risk for future infertility and may desire a fertility status assessment (FSA), defined as semen analysis for males and consultation with a reproductive specialist for females. The purpose of this study was to describe the proportion of, and factors associated with, interest in FSA among young adult survivors of childhood cancer.

Methods: This retrospective single-institution review included patients with prior gonadotoxic treatment, aged 18-25 years and >1 year from cancer treatment completion, who received a fertility-focused discussion during survivorship.

Article Synopsis
  • - This study investigates chronic symptoms experienced by young adult survivors of childhood cancer, aiming to identify specific clusters of these symptoms post-treatment.
  • - Researchers analyzed data from 579 survivors and identified three main symptom clusters: gastrointestinal (e.g., nausea, pain), psychological (e.g., depression, anxiety), and neurologic (e.g., fatigue, weakness), with varying prevalence across different demographic groups.
  • - The clusters were validated through statistical methods, showing that the gastrointestinal and psychological clusters were consistent across most subgroups, indicating a need for further research into the symptoms affecting these cancer survivors.

Background: Targeted anticancer therapies such as BCR-ABL tyrosine kinase inhibitors (TKIs) have improved outcomes for chronic myeloid leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph + ALL). However, little is known about long-term risks of TKIs in children. Exposure-based survivorship guidelines do not include TKIs, thus surveillance practices may be variable.

The reproductive concerns of emerging adult survivors of childhood cancer are not well described, and valid measurement tools tailored to this population are lacking. The purpose of this analysis was to evaluate a modified version of the Reproductive Concerns Scale (mRCS) among male and female survivors of childhood cancer. This is a secondary analysis of cross-sectional survey data collected from patients enrolled on an infertility-educational intervention study.

Objectives: This study describes the hormone profiles for gonadal late effects after alkylator-based hematopoietic stem cell transplant (HSCT) regimens used for sickle-cell disease (SCD).

Methods: This is a retrospective chart review of subjects followed in the post-HSCT clinic for sickle-cell disease. Patient demographics, pubertal development, characteristics of pre-HSCT disease severity, treatment before HSCT, conditioning regimens, presence of graft versus host disease and follicle-stimulating hormone, anti-Müllerian hormone (AMH), luteinizing hormone and testosterone were abstracted from the medical record.

Background: Providers often rely on self-reported ovarian function in adolescent and young adult (AYA)-aged childhood cancer survivors when making clinical decisions. This study described reported menstrual patterns and the agreement between respondent-reported and biochemical premature ovarian insufficiency (POI) in this population.

Procedure: This was a cross-sectional study of survivors (or their parent proxy) aged 13-21.

Background: Children diagnosed with cancer are living longer and the survivor population is growing. However, most survivors develop late effects of radiation and chemotherapy shortly to years after completion of therapy, and the receipt of follow-up visits that are recommended by the Children's Oncology Group (COG) is suboptimal nationally.

Aims: The aims of this study are to: 1) evaluate the impact of a patient-controlled electronic personal health record (ePHR) and system (SurvivorLink) on care visit attendance, risk-based surveillance, and other secondary outcomes (i.

Purpose: Current guidelines recommend screening at-risk childhood cancer survivors for ovarian dysfunction using follicle-stimulating hormone (FSH). However, FSH identifies diminished ovarian reserve (DOR), a component of ovarian dysfunction, in the later stages when fertility preservation is less likely to succeed. This analysis evaluates the utility of anti-Mullerian hormone (AMH) for the assessment of DOR in adolescent and young adult (AYA)-aged survivors of childhood cancer.
