Background: The Patient Protection and Affordable Care Act (ACA) allowed Americans aged 19-25 years to remain on their parents' health insurance plans until age 26 years (the Dependent Care Expansion [DCE]). Have those with cancer diagnoses benefited?

Methods: The ACE DCE 7-year age range of 19-25 years was compared for changes in cancer survival and mortality before and after enactment of the ACA with groups that were younger and older (in 7-year age spans: ages 12-18 and 26-32 years, respectively). Cancer death data for the entire United States were obtained from the Centers for Disease Control and Prevention, and relative survival data of patients who were diagnosed with cancer were obtained from the National Cancer Institute Surveillance, Epidemiology, and End Results regions representing 42%-44% of the country.

For young adults with acute lymphoblastic leukemia, pediatric-based regimens are likely to provide the following when compared to hyper-CVAD regimens: better disease control, less hospitalization time, diminished acute toxicities, decreased financial cost, more quality-adjusted life years, and fewer adverse late effects, such as infertility, myelodysplasia, and second malignant neoplasms. There are also reasons to expect less cardiac and cognitive dysfunction after pediatric regimens. The improved quality and quantity of life associated with pediatric regimens renders them preferable to hyper-CVAD regimens for the treatment of Philadelphia-negative B-precursor or T-cell acute lymphoblastic leukemia and lymphoblastic lymphoma in young adults.

In the United States, adolescent and young adult (AYA) patients with cancer have the lowest clinical trial participation rate of all age groups and slower progress in survival improvement than younger patients. Ominously, AYA clinical trial participation has been steadily decreasing since 2010, except in 15-19 year olds and AYAs with acute lymphoblastic leukemia. In order to reverse the accrual trend, multiple changes are necessary, including convincing community oncologists to pursue clinical trials on behalf of their AYA patients and to have the new National Community Oncology Research Program and National Clinical Trials Network lead a coordinated effort to increase accrual.

Importance: The incidence of acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) in adolescent and young adult (AYA) patients (age range, 15-39 years) in the United States is increasing at a greater rate than in younger or older persons. Their optimal treatment has been increasingly debated as pediatric regimens have become more widely used in the age group. This review compares the basic features of pediatric and adult chemotherapy regimens for ALL and LBL, recognizes and describes the challenges of the pediatric regimen, and suggests strategies to facilitate its adoption for AYAs with ALL and LBL.

We outline here the essential elements of training for health care professionals who work with adolescent and young adult (AYA) patients with cancer. Research is emerging that a number of cancers manifest themselves differently in the AYA population, both in terms of biology and treatment response. In addition, there are a number of issues uniquely experienced by the AYA population that are critical for health care professionals working within AYA oncology (AYAO) to understand.

One of the challenges of incorporating molecularly targeted drugs into multi-agent chemotherapy (backbone) regimens is defining dose-limiting toxicities (DLTs) of the targeted agent against the background of toxicities of the backbone regimen. An international panel of 22 pediatric acute lymphocytic leukemia (ALL) experts addressed this issue (www.ALLNA.

Background: While carotid artery disease and strokes have been documented in adult cancer patients treated with neck irradiation, little information is available on pediatric patients. The purpose of this study is to determine if carotid disease is more prevalent among pediatric cancer survivors treated with neck irradiation than among healthy controls.

Procedure: Thirty pediatric cancer survivors who received neck irradiation (2,000-6,660 cGy) and 30 healthy subjects underwent bilateral carotid ultrasounds.

Pediatric lymphoblastic lymphoma (LL) has utilized treatment strategies similar to childhood acute lymphoblastic leukaemia (ALL) with prolonged maintenance chemotherapy. We report the results of a pilot study to estimate the feasibility, toxicity and efficacy of a 12-month aggressive multi-agent chemotherapy regimen in children and adolescents with advanced LL. Between July 1994 and June 1997, 85 eligible children and adolescents with advanced LL (Stage III/IV) were enrolled on this pilot study.

Background: NY-ESO-1 is a human gene that codes for antigens that are expressed in malignancies of various histological types, but not in normal tissues, except the testes. The expression of NY-ESO-1 in intracranial brain tumors including astrocytomas (ASTRs) and medulloblastomas (MEDs)/primitive neuroectodermal tumors (PNETs) was examined since the expression of NY-ESO-1 has only previously been explored in depth in neuroblastomas.

Materials And Methods: During our immunohistochemical study, a sensitive, four-step, alkaline phosphatase-conjugated antigen detection technique was employed.

Article Synopsis
  • The study investigates how obesity affects outcomes in pediatric patients diagnosed with acute lymphoblastic leukemia (ALL), specifically looking at event-free survival and relapse rates.
  • Data from over 4,000 patients diagnosed between 1988 and 1995 reveals that obese patients have a lower 5-year event-free survival rate (72%) compared to nonobese patients (77%), along with a higher risk of relapse.
  • The findings highlight that obesity at diagnosis is a significant predictor of poorer outcomes in preteens and adolescents with ALL, regardless of chemotherapy treatment specifics.

Vascular endothelial growth factor (VEGF) is a homodimeric, disulfide-linked glycoprotein which exhibits endothelial cell-specific mitogenic properties. VEGF is also a potent inducer of vascular permeability. There is considerable experimental evidence that VEGF isoforms are strongly involved in provoking neoangiogenesis of neoplastic cells and, consequently, the growth and progression of primary neoplasms (i.
