New therapeutic options for gynecological cancers (in particular, targeted therapies and immunotherapies) are associated with potential cardiovascular toxicities that oncologists should be able to identify, detect and manage together with a cardiologist. The first step consists of evaluating the patient's individual cardiovascular risk, regardless of planned oncologic treatment, to determine whether this treatment can be initiated immediately or if cardiological advice is required. In a second step, the risk of cardiovascular toxicity of the selected treatment must be assessed, considering its intrinsic risk and the patient's comorbidities. Once treatment has started, appropriate monitoring should be implemented during administration, and after discontinuation. Beyond general recommendations, specific situations are detailed for initial workup and surveillance relating to most common protocols of chemotherapy, immunotherapy, targeted therapy and associations used in gynecological oncology. If cardiotoxicity occurs (hypertension, QT interval increase, left ventricular dysfunction, troponin increase, myocarditis), the oncologist must be aware of the principles of management, and distinguish between what he can manage on his own and what requires referring to specialists. Prior to rechallenge after cardiotoxicity, multidisciplinary discussion is mandatory to assess the patient's benefit/risk ratio.

The growing number of cancer cases induces increasing pressure on oncology and hematology departments, creating the need for alternatives such as hospitalization at home (HAH). The Carfil-HAD pilot study aimed to assess the feasibility and safety of administering short-duration intravenous carfilzomib infusions at home for the treatment of multiple myeloma. Among the 17 patients included, 15 received 128 infusions of Carfilzomib under a combined Outpatient Hospital (OH)/HAH scheme, are evaluable. Deviations from standard operating procedures were monitored, quality of life and satisfaction were evaluated, and a cost-effectiveness analysis compared the mixed OH/HAH model to exclusive OH care. The results confirmed feasibility: of 128 infusions, 42 were performed in OH and 86 in HAH without serious incident or interruption of care, with 96% of deviations classified as minor. Quality of life is not affected by the mixed care organization, and patient satisfaction was very high. From an economic perspective, the OH/HAH model generated savings of €610 per treatment cycle, nearly half the cost of hospital-based care. In conclusion, intravenous administration of carfilzomib in HAH is feasible and safe. This organization could be applied to other oncological therapies to offer a wider range of outpatient's care.

Although immune-mediated colitis is well known and is one of the most common toxicities of Immune Checkpoint Inhibitors (ICIs), the toxicity of these agents to the upper digestive tract is largely unknown and its incidence is probably underestimated. It can affect the stomach and/or the duodenum, and much more rarely the esophagus. Involvement of several segments is common, as is the association with colitis and possibly extra-digestive toxicity(ies). Severity is extremely variable, but severe forms are possible, particularly due to hydro-electrolytic and nutritional repercussions, possible haemorrhagic complications, and much more rarely, a risk of perforation. Many differential diagnoses must be considered. Therapeutic modalities are partly modeled on those of colitis, and the choices must be discussed and validated in multidisciplinary meetings, taking into account the entire "spectrum" of toxicity. We propose a review of the data available in the literature concerning the toxicity of ICIs on the upper digestive tract, illustrated by a few cases from our center.

Prostate cancer mainly affects older men and is treated with hormone therapy, often in combination with other treatments. Particular attention must be paid to the side effects of treatments that impact patients' quality of life. Comprehensive care and regular monitoring by a multidisciplinary team supported by supportive oncology care, coordinated by an advanced practice nurse or coordinating nurse, ensure optimal and safe care.

As the number of cancer treatments increases, new specific toxicities are emerging, requiring early and specialized treatment. The Gustave-Roussy center in Villejuif, near Paris, has set up a multidisciplinary toxicity pathway (ImmunoTox multidisciplinary consultation meeting, day hospital, mobile team). This includes an advanced practice nurse to optimize the management of undesirable effects, improve quality of life and mobilize all related skills.

Oral adjuvant hormone therapy for early breast cancer, despite its proven importance in terms of survival and prevention of recurrence, does not fall within the scope of clinical pharmacy programs set up for oral anticancer drugs, even though issues of therapeutic adherence have been clearly identified. The aim of our study was to explore the perception of healthcare professionals regarding the prescription and dispensing of this hormone therapy, in order to identify the risks for these patients and determine the clinical pharmacy actions that could address these risks.

Therapeutics used in cancer treatment can cause vestibular ototoxicity, which is particularly challenging to detect due to the frequent occurrence of nausea and vomiting in patients experiencing significant fatigue and stress. An appropriate diagnosis enables optimal symptom correction, reduces the risk of falls, and improves quality of life.

Immune checkpoint inhibitors (ICI) have revolutionized the treatment of solid tumors. However, they can induce immune-related adverse effects (irAEs) that can affect any organ. These irAEs are different from the side effects of traditional oncological treatments and require specific management. Given the increasing use of ICI, first-line care will increasingly need to manage these irAEs. This article aims to assist in the implementation of the guidelines for managing irAEs, with a particular focus on aspects related to first-line care.

Drug-induced immune thrombocytopenia (DIIT) is a rare cause of immune thrombocytopenia, characterized by the formation of drug-dependent antiplatelet antibodies. DIIT can lead to life-threatening hemorrhage. The diagnosis is difficult, relying on the detection of antiplatelet antibodies in patient's serum exclusively in the presence of the implicated drug. The gold standard test is the monoclonal antibody immobilization of platelet antigens (MAIPA), although other techniques (flow cytometry and Luminex®) can be used.

Lyme borreliosis is suspected when there are compatible symptoms associated with tick exposure. The diagnosis, except for erythema migrans, is based on serology. However, in some cases, serology may be erroneous.

Febrile neutropenia is a medical emergency requiring rapid and rigorous management considering the risk of severe infection. Febrile neutropenia is a frequent complication in patients receiving chemotherapy. Initial assessment is vital in order to decide the follow-up (outpatient treatment, conventional care or intensive care unit) and to initiate adapted antibiotic therapy as soon as possible. Depending on the infectious syndrome (clinically documented, microbiologically documented or undocumented), antibiotic therapy should be adapted or discontinued, considering the recovery from aplasia and absence of fever. Antifungal agents are not systematically used and its use should be discussed according to the context. G-CSF should be used prophylactically, and is not an adjunct to antibiotic therapy for febrile neutropenia. Granulocyte transfusions are exceptionnally indicated and its use should be discussed on a case-by-case basis. Standard precautions are adequate for the majority of patients, with the exception of specific situations.

Children and adolescents who are being treated or have been treated for acute leukemia have a secondary immunodeficiency linked to chemotherapy, resulting in an increased risk of infections. Some of which can be prevented by vaccination but its effectiveness is not optimal during chemotherapy. Upon cessation of chemotherapy, the time required for immune reconstitution varies from three months to more than a year, depending on lymphocyte subpopulations, the patient's age, and the intensity of the treatment received. Although they may have regained their immune functions, studies show that most patients have lost part of their vaccine-induced protection post-chemotherapy and require booster doses of vaccines. Most practitioners agree on the importance of vaccinating or revaccinating these children, but practices are heterogeneous among pediatric hematologist-oncologists in France. Based on a practice study and a recent review of the literature, this work aims to propose new French recommendations for the vaccination strategy to be adopted for children and adolescents treated or recently treated for acute leukemia, excluding allogeneic transplant recipients, in 2024. These recommendations specifically include the vaccination protocols for human papillomavirus and meningococcal infections but do not address the COVID-19 vaccination, as its guidelines are subject to rapid changes.

The covalent Bruton tyrosine kinase inhibitors (iBTKs) have profoundly transformed the management of B-cell lymphoid malignancies, particularly chronic lymphocytic leukemia (CLL). These targeted therapies, with ibrutinib as the pioneer, have paved the way for significant improvement in the prognosis of many patients. With second-generation iBTKs such as acalabrutinib and zanubrutinib, the therapeutic landscape has expanded, offering potential new options for patients with CLL. This review focuses on the cardiovascular adverse effects associated with these treatments. It delves into the underlying pathophysiological mechanisms of these effects, highlighting the complex interactions between these molecules and the cardiovascular system. Additionally, it examines the frequency of adverse effects according to the type of iBTK, drawing on data from clinical trials and real-world clinical practice. Finally, the importance of close cardio-oncological monitoring is emphasized, with essential collaboration between hematologists and cardiologists. Strategies for screening and managing cardiovascular adverse effects are also discussed, emphasizing the need for a proactive approach in managing these complications. Experts propose a pragmatic follow-up of these patients, through a central illustration and a figure adapted from European cardio-oncology guidelines, to simplify hematologists' practice.

A large body of literature highlights the importance of energy metabolism in the response of haematological malignancies to therapy. In this review, we are particularly interested in acute myeloid leukaemia, where mitochondrial metabolism plays a key role in response and resistance to treatment. We describe the new concept of mitohormesis in the response to therapy-induced stress and in the initiation of relapse in this disease.

Therapeutic options for breast cancer have recently been enriched by new antibody-drug conjugates (ADC), which are now being utilized across all known molecular subtypes. ADCs represent a groundbreaking class of therapies that combine a cytotoxic agent with a monoclonal antibody via a combination molecule (linker). The primary objective is to selectively deliver chemotherapy to cells expressing the target antigen, thereby enhancing the therapeutic index. Trastuzumab-emtansine marked the pioneering use of this approach for HER2-overexpressed breast cancer. More recently, trastuzumab-deruxtecan and sacituzumab-govitecan have demonstrated efficacy in progression-free survival and overall survival in HER2-overexpressed and HER2-low breast cancer for the former, and HER2-non-overexpressed (including HER-low) for the latter. Numerous other ADCs are currently under development in breast cancer. While ADCs were initially designed to widen the therapeutic index and mitigate toxicities, managing ADC-related adverse events in the clinical setting remains a challenge. This review article aims to provide an overview of the toxicity profiles of these drugs already in current clinical practice or under development, drawing from results observed in various studies.

Chemotherapy-induced nausea and vomiting (CINV) are frequent and dreaded side effects in cancer treatments. CINV has a major impact on patient's condition and quality of life. Prophylaxis is tailored to patient's profile and the emetogenic level of their chemotherapy. The aim of this study is to update the recommendations for CINV prevention and management in pediatric onco-hematology for use in France, by adapting the guidelines of the Pediatric Oncology Group of Ontario (POGO). Clinical practice guideline adaptation is a recognized method for tailoring existing clinical practice guidelines to local context. A multidisciplinary French-speaking panel was formed to discuss about POGO guideline recommendations for the acute and delayed phases, breakthrough, refractory and anticipatory CINV and the evidence supporting them. Panel members were asked whether they wanted to adopt, modify or reject each of the POGO guideline recommendations. Panel members translated each recommendation and adapted recommendations for an implementation in France. Their acceptance required agreement at least 80 % of panel members. Algorithms and tables were created, listing all the recommendations and providing a better overview for decision-making process adapted to the patient's profile. These recommendations should be reviewed for implementation at French institutions caring for pediatric cancer patients and once implemented, the rates of adherence to recommendations and CINV control should be reported.

In France, the breast cancer is the most common cancer among women under the age of 40. From 38 to 70% of women have not fulfilled their parental plans at the time of diagnosis. The gonadotoxicity of the treatments and the follicular physiological decline linked to age can become an obstacle to this project.

The announcement of a cancer diagnosis is traumatic for the patient. In France, an announcement system has been in place, providing medical time for announcement and treatment proposal, nursing time for support, without including the pharmacist. In order to improve management of patients treated with intravenous anticancer drugs, we set up introductory pharmaceutical consultations in digestive oncology. The aims were to assess the situation one year after the introduction of these consultations, and to assess their contribution.
