Characteristics and treatment of acute myeloid neoplasms with cutaneous involvement in infants up to 6 months of age: A retrospective study.

BACKGROUND: Myeloid neoplasms account for 50% of cases of pediatric leukemias in infants. Approximately 25%-50% of patients with newborn leukemia have cutaneous extramedullary disease (EMD). In less than 10% of patients, aleukemic leukemia cutis or isolated extramedullary disease with cutaneous involvement (cEMD) occurs when skin lesions appear prior to bone marrow involvement and systemic symptoms. Interestingly, in acute myeloid leukemia with cutaneous EMD (AML-cEMD) and cEMD, spontaneous remissions have been reported. METHOD: This is a multicentric retrospective cohort study aiming to describe characteristics, treatment, and outcome of infants with either cEMD or presence of cutaneous disease with involvement of the bone marrow (AML-cEMD). This study included patients born between 1990 and 2018 from Italy, the Netherlands, Switzerland, and the United States, diagnosed between 0 and 6 months of life with cEMD or AML-cEMD. Descriptive statistics, Fisher's exact test, Kaplan-Meier method, and log rank test were applied. RESULTS: The cohort consisted of n = 50 patients, including 42 AML-cEMD and eight cEMD patients. The most common genetic mutation found was a KMT2A rearrangement (n = 26, 52%). Overall 5-year event-free survival (EFS) and overall survival (OS) were 66% [confidence interval (CI): 51-78] and 75% [CI: 60-85], respectively. In two patients, complete spontaneous remission occurred without any therapy. Central nervous system (CNS) involvement was found in 25% of cEMD patients. No difference in outcomes was observed between the AML-cEMD and cEMD groups, but none of the latter patients included in the study died. KMT2A rearrangements were not associated with poorer prognosis. CONCLUSION: In the largest cohort to date, our study describes the characteristics of infants with cutaneous involvement of myeloid neoplasms including cytomolecular findings and survival rates. Further prospective biologic and clinical studies of these infants with myeloid neoplasms will be required to individualize therapy for this rare patient population.

Gynaecological follow-up for women of reproductive age with multiple sclerosis: The GYNESEP study.

BACKGROUND: The gynaecological care of women with Multiple Sclerosis has received little attention; most reports focussed on pregnancy or sexuality. The objective of the present study was to evaluate if gynaecological follow-up for women of reproductive age with Multiple Sclerosis was adequate. METHODS: We performed a cross-sectional study on a large cohort of women with Multiple Sclerosis aged 18-40 years. All participants completed online questionnaires on general health status, gynaecological follow-up, and sexuality. Expanded Disability Status Scale (EDSS) scores were extracted from medical records. The study was registered in clinicaltrials.gov with the number NCT05248438, and in the European database ID-RCB with the number 2021-A02912-39. RESULTS: Of the 192 patients who completed questionnaires, 157 (82.2%) reported gynaecological follow-up. Of the 155 patients on immunosuppressive treatments, only 31 (20%) underwent annual cervical screening. Of the 140 patients who met the French papillomavirus vaccination age recommendations, only 50 (35.7%) were vaccinated. A total of 128 (66.7%) patients used contraception. However, 16 (8.3%) patients reported unplanned pregnancies since the time of diagnosis. CONCLUSION: Women with Multiple Sclerosis require more information on reproductive health and prevention of cancer. Better contraceptive advice would reduce the number of unplanned pregnancies and avoid foetal exposure to potentially teratogenic treatment.
