Right ventricular thrombus (RVT) is a rare but clinically significant condition associated with severe complications, such as pulmonary embolism and right heart failure. This case report presents a 68-year-old woman with a history of diabetes, coronary artery disease, and heart failure with reduced ejection fraction (HFrEF), who developed bilateral ventricular thrombi in the context of septic cardiomyopathy secondary to a diabetic foot infection and a urinary tract infection (UTI). Echocardiography revealed thrombi in both the right and left ventricles, severe global hypokinesia, and reduced ejection fraction.

This case report details a patient with Crohn's disease (CD) who developed acute lymphoblastic leukemia (ALL) 16 years after their initial diagnosis. Various immunosuppressive therapies used in the treatment included azathioprine, infliximab and, for a short period, vedolizumab and steroids for CD and hyper-CVAD chemotherapy for leukemia. The association between CD and increased cancer risk, particularly hematological malignancies, emphasizes the importance of regular cancer surveillance, including hematological assessments, for patients on immunosuppressive therapy.

Purpose: Describe clinical characteristics and outcome of Li-Fraumeni syndrome (LFS)-associated osteosarcomas.

Methods: TP53 germline pathogenic/likely pathogenic variant carriers diagnosed with osteosarcoma in France between 1980 and 2019 were identified via the French Li-Fraumeni database at Rouen University Hospital. Sixty-five osteosarcomas in 52 patients with available clinical and histological data were included.

Background: Previous studies have shown that neutrophil-to-lymphocyte (NLR) ratio at diagnosis and early lymphocytes recovery on doxorubicin-based chemotherapy, may impact the outcome in patients with osteosarcoma (OST). This study aimed to evaluate the prognostic value of hemogram parameters in patients with OST treated with high-dose methotrexate and etoposide/ifosfamide (M-EI) chemotherapy.

Materials And Methods: We retrospectively analyzed the prognostic value of various hemogram parameters at diagnosis and during therapy in a large consecutive cohort of patients with OST included in the French OS2006 trial and treated with M-EI chemotherapy.

Article Synopsis
  • Monoclonal antibodies like gantenerumab target amyloid-beta to potentially slow decline in Alzheimer’s symptoms, being a fully human anti-Aβ antibody.
  • Two phase 3 trials (GRADUATE I and II) involved nearly 2,000 participants aged 50-90 with early signs of Alzheimer’s, comparing gantenerumab with a placebo over 116 weeks.
  • Although the trials showed some differences in amyloid levels and cognitive scores between tretament groups, the results were not statistically significant, indicating gantenerumab might not significantly alter cognitive decline compared to placebo.

Article Synopsis
  • Germ cell tumors (GCT) are a type of brain cancer that mostly affects teenagers and young adults, but they can often be treated successfully with chemotherapy and radiation therapy.
  • A study looked at 17 patients treated for these tumors, and most of them had good results, with only one person having a relapse.
  • Proton beam radiation (PBT) was shown to be a safe and effective treatment, helping to keep patients' brains working well without causing serious side effects.

Background: Diffuse intrinsic pontine glioma (DIPG) is a fatal disease with a median overall survival (OS) of less than 12 months after diagnosis. Radiotherapy (RT) still remains the mainstay treatment. Several other therapeutic strategies have been attempted in the last years without a significant effect on OS.

Background: Ewing sarcoma (ES) is a rare and aggressive pediatric cancer. Numerous studies have attempted to identify new prognostic biomarkers. The predictive value of serum LDH and CRP has not been clearly described, to date.

The occurrence of cancer in newborns within the first 28 days of life is uncommon, with different clinical presentation from other age groups. Prenatal diagnosis is reported in about half of patients, while a genetic predisposition condition is supposed. The management of a newborn with cancer can be challenging and needs to be tailored according to the histology and the primary tumor site; surgery represents the main strategy, while chemotherapy should be considered with caution because of the higher toxicity and mortality due to different pharmacokinetics in neonates compared to older children.

Unlabelled: The outcomes of adolescents/young adults with osteosarcoma have not improved in decades. The chaotic karyotype of this rare tumor has precluded the identification of prognostic biomarkers and patient stratification. We reasoned that transcriptomic studies should overcome this genetic complexity.

Phase II immuno-oncology clinical trials screen for efficacy an increasing number of treatments. In rare cancers, using historical control data is a pragmatic approach for speeding up clinical trials. The drop-the-losers design allows dropping off ineffective arms at interim analyses.

In anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma (ALK+ ALCL), positive minimal residual disease (MRD+) after the first chemotherapy course was proven of strong prognostic significance. We aimed to validate these results in 138 French patients. Eighty-seven patients had a detectable minimal disseminated disease at diagnosis (MDD+).

Given the very poor prognosis for children with recurrent medulloblastoma, we aimed to identify prognostic factors for survival post-relapse in children with childhood medulloblastoma. We retrospectively collected clinico-biological data at diagnosis and main clinical characteristics at relapse of children newly diagnosed with a medulloblastoma between 2007 and 2017 at Gustave Roussy and Necker Hospital. At a median follow-up of 6.

Background: To evaluate the influence of automated visual field (VF) testing on intraocular pressure (IOP) in patients with ocular hypertension (OHT) or glaucoma.

Methods: We conducted a prospective observational study in the glaucoma department at Quinze-Vingts National Ophthalmology Hospital in Paris. Ninety-five right eyes of 95 patients followed for glaucoma or OHT were included.

Relapses involving the central nervous system (CNS) are rare in children and adolescents with ALK+ anaplastic large cell lymphoma (ALCL) treated with regimens including CNS prophylaxis. Early identification of patients at high-risk for CNS relapse would enable stratification and better adaptation of initial treatment especially in the light of the upcoming targeted therapies with limited CNS penetration. We analyzed clinical and histological data of all ALK+ALCL patients with CNS relapse registered in ALCL99-database with the aim to describe risk factors and outcome.

Background/aims: In oncology, new combined treatments make it difficult to order dose levels according to monotonically increasing toxicity. New flexible dose-finding designs that take into account uncertainty in dose levels ordering were compared with classical designs through simulations in the setting of the monotonicity assumption violation. We give recommendations for the choice of dose-finding design.

Purpose: The purpose of this work is to assess the clinical outcome of pediatric patients diagnosed with pheochromocytoma and paraganglioma (PPGL) detected in France since 2000.

Methods: A retrospective multicenter study was conducted that included all patients younger than 18 years with PPGL diagnosed in France between 2000 and 2016. Patients were identified from 4 different sources: the National Registry of Childhood Solid Tumors, the French Pediatric Rare Tumors Database, the French registry of succinate dehydrogenase (SDH)-related hereditary paraganglioma, and the nationwide TenGen network.

Background: Previous pilot studies have shown the feasibility of preoperative chemotherapy in patients with medulloblastoma, but benefits and risks compared with initial surgery have not been assessed.

Methods: Two therapeutic strategies were retrospectively compared in 92 patients with metastatic medulloblastoma treated at Gustave Roussy between 2002 and 2015: surgery at diagnosis (n = 54, group A) and surgery delayed after carboplatin and etoposide-based neoadjuvant therapy (n = 38, group B). Treatment strategies were similar in both groups.
