CE: Cardiotoxicity and Breast Cancer as Late Effects of Pediatric and Adolescent Hodgkin Lymphoma Treatment

Anthracycline cardiotoxicity: current methods of diagnosis and possible role of 18F-FDG PET/CT as a new biomarker

Despite advances in chemotherapy, the drugs used in cancer treatment remain rather harmful to the cardiovascular system, causing structural and functional cardiotoxic changes. Positron-emission tomography associated with computed tomography (PET/CT) has emerged like a promising technique in the early diagnosis of these adverse drug effects as the myocardial tissue uptake of fluorodeoxyglucose labeled with fluorine-18 (¹⁸F-FDG), a glucose analog, is increased after their use. Among these drugs, anthracyclines are the most frequently associated with cardiotoxicity because they promote heart damage through DNA breaks, and induction of an oxidative, proinflammatory, and toxic environment. This review aimed to present the scientific evidence available so far regarding the use of ¹⁸F-FDG PET/CT as an early biomarker of anthracycline-related cardiotoxicity. Thus, it discusses the physiological basis for its uptake, hypotheses to justify its increase in the myocardium affected by anthracyclines, importance of ¹⁸F-FDG PET/CT findings for cardio-oncology, and primary challenges of incorporating this technique in standard clinical oncology practice.

CE: Caring for Survivors of Hodgkin Lymphoma

: Hodgkin lymphoma (HL) is a highly curable cancer. Advances in diagnosis and treatment have resulted in excellent cure rates, producing an ever-increasing number of HL survivors who live decades beyond their initial cancer treatment. These survivors, however, are at risk for late effects secondary to the cancer treatments they received years earlier, most notably, subsequent primary cancers, cardiovascular disease, pulmonary toxicity, and endocrine dysfunction. Monitoring and managing such late treatment effects may significantly challenge survivors' long-term health care providers, who may need to take on increased survivorship care. For physicians and nurses working outside of oncology settings, who are increasingly called upon to collaborate with oncologists when caring for HL survivors, understanding the late treatment effects and potential risk factors facing this growing patient population is essential to the provision of comprehensive long-term care. The authors provide an overview of HL, review the most commonly encountered late adverse effects of treatment, and discuss current recommendations for survivor surveillance and screening.

Adolescent and young adult Hodgkin lymphoma: Raising the bar through collaborative science and multidisciplinary care

Hodgkin lymphoma (HL) is one of the most common cancers in the adolescent and young adult (AYA) population (15-39 years). Despite continued improvements in HL outcomes, AYAs have not exhibited survival gains to the same extent as other age groups. At present, details about tumor biology, optimal therapeutic approaches, supportive care needs, and long-term toxicities in AYAs with HL remain understudied. Herein, we summarize the current state of the AYA population with HL, specifically focusing on how collaborations across the pediatric and medical oncology divide, coupled with multidisciplinary patient care, can further optimize outcomes for this group of patients.
