Imatinib resistance: diagnostic and therapeutic choices

We report a case of a 42-year-old woman with t(9;22) positive chronic myeloid leukemia (CML) who developed a sub-optimal response to therapy with imatinib mesylate due to M351T mutation and low plasma level of imatinib. Dose increase of imatinib resulted in toxicity. She obtained a complete molecular response to therapy with nilotinib, without adverse events

Management of Germ Cell Tumors During the Outbreak of the Novel Coronavirus Disease-19 Pandemic:A Survey of International Expertise Centers

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has become a public health emergency affecting frail populations, including patients with cancer. This poses the question of whether cancer treatments can be postponed or modified without compromising their efficacy, especially for highly curable cancers such as germ cell tumors (GCTs). MATERIALS AND METHODS: To depict the state-of-the-art management of GCTs during the COVID-19 pandemic, a survey including 26 questions was circulated by e-mail among the physicians belonging to three cooperative groups: (a) Italian Germ Cell Cancer Group; (b) European Reference Network-Rare Adult Solid Cancers, Domain G3 (rare male genitourinary cancers); and (c) Genitourinary Medical Oncologists of Canada. Percentages of agreement between Italian respondents (I) versus Canadian respondents (C), I versus European respondents (E), and E versus C were compared by using Fisher's exact tests for dichotomous answers and chi square test for trends for the questions with three or more options. RESULTS: Fifty-three GCT experts responded to the survey: 20 Italian, 6 in other European countries, and 27 from Canada. Telemedicine was broadly used; there was high consensus to interrupt chemotherapy in COVID-19-positive patients (I = 75%, C = 55%, and E = 83.3%) and for use of granulocyte colony-stimulating factor primary prophylaxis for neutropenia (I = 65%, C = 62.9%, and E = 50%). The main differences emerged regarding the management of stage I and stage IIA disease, likely because of cultural and geographical differences. CONCLUSION: Our study highlights the common efforts of GCT experts in Europe and Canada to maintain high standards of treatment for patients with GCT with few changes in their management during the COVID-19 pandemic. IMPLICATIONS FOR PRACTICE: Despite the chaos, disruptions, and fears fomented by the COVID-19 illness, oncology care teams in Italy, other European countries, and Canada are delivering the enormous promise of curative management strategies for patients with testicular cancer and other germ cell tumors. At the same time, these teams are applying safe and innovative solutions and sharing best practices to minimize frequency and intensity of patient contacts with thinly stretched health care capacity

Characterization of three novel pathogenic SLC40A1 mutations and genotype/phenotype correlations in 7 Italian families with type 4 hereditary hemochromatosis

Mutations of SLC40A1 encoding ferroportin (Fpn), the unique cellular iron exporter, severely affect iron homeostasis causing type 4 hereditary hemochromatosis, an autosomal dominant iron overload condition with variable phenotypic manifestations. This disease can be classified as type 4A, better known as “ferroportin disease”, which is due to “loss of function” mutations that lead to decreased iron export from cells, or as type 4B hemochromatosis, which is caused by “gain of function” mutations, conferring partial or complete resistance to hepcidin-mediated Fpn degradation. In this work, we discuss clinical and molecular findings on a group of patients in whom a SLC40A1 single copy missense variant was identified. Three novel variants, p.D181N, p.G204R and p.R296Q were functionally characterized. Fpn D181N and R296Q mutants can be classified as full or partial loss of function, respectively. Replacement of G204 with arginine appears to cause a more complex defect with impact both on iron export function and hepcidin sensitivity. This finding confirms the difficulty of predicting the effect of a mutation on the molecular properties of Fpn in order to provide an exhaustive explanation to the wide variability of the phenotype in type 4 hereditary hemochromatosi

Impact on mental health, disease management, and socioeconomic modifications in hematological patients during the COVID-19 pandemic in Italy

Background: Hematological patients are a highly vulnerable population with an increased risk of developing severe COVID-19 symptoms due to their immunocompromised status. COVID-19 has proven to cause serious mental health issues, such as stress, anxiety, and depression in the general population. However, data on the psycho-social impact of COVID-19 on hematological patients are lacking. Objectives: This study aims to examine the psychological well-being of hematological patients in Italy during the initial period of the COVID-19 pandemic. Furthermore, it seeks to explore the association between modifications in the management of hematological diseases and employment status of these patients during the COVID-19 pandemic and the resulting mental health outcomes. Design and Methods: A survey using the DASS-21 questionnaire was administered to 1105 hematological patients. Data analysis was conducted using the R software, and logistic regression analysis was performed to predict the association between hematological patient/general population and employment status with DASS scores. Results: The hematological patient population reported significantly higher levels of depression (OR 0.947, 95% CI 0.966–0.982, p  < 0.001), anxiety (OR 0.948, 95% CI 0.939–0.958, p  < 0.001), and stress (OR 0.984, 95% CI 0.977–0.992, p  < 0.001) compared with the general population. A significant relationship has been found in stress between employed and unemployed patients (OR 1.015, 95% CI 1.000–1.030, p  = 0.044), as well as in the control group (OR 1.024, 95% CI 1.010–1.039, p  = 0.001). In addition, employment status is significantly related to depression, anxiety, and stress in both the hematological patient group and the general population. Conclusion: During the initial phase of the COVID-19 pandemic, hematological patients had elevated levels of depression, anxiety, and stress compared with the general population. The delay in their treatment and employment status played a role in their mental health outcomes. These findings emphasize the importance of further research to gain deeper insight into the long-term psychological effects and explore effective strategies for managing mental health in similar crises

Thrombosis and survival in essential thrombocythemia: A regional study of 1,144 patients

To identify prognostic factors affecting thrombosis-free survival (TFS) and overall survival (OS), we report the experience of a Regional cooperative group in a real-life cohort of 1,144 patients with essential thrombocythemia (ET) diagnosed from January 1979 to December 2010. There were 107 thrombotic events (9.4%) during follow-up [60 (5.3%) arterial and 47 (4.1%) venous thromboses]. At univariate analysis, risk factors for a shorter TFS were: age >60 years (P 60 years (P 15 × 10(9) /l (P = 0.0370) were independent risk factors. Previous thrombotic events in ET patients are crucial for TFS but their importance seems related not to the occurrence per se but mainly to the interval between the event and the diagnosisTo identify prognostic factors affecting thrombosis-free survival (TFS) and overall survival (OS), we report the experience of a Regional cooperative group in a real-life cohort of 1,144 patients with essential thrombocythemia (ET) diagnosed from January 1979 to December 2010. There were 107 thrombotic events (9.4%) during follow-up [60 (5.3%) arterial and 47 (4.1%) venous thromboses]. At univariate analysis, risk factors for a shorter TFS were: age >60 years (P < 0.0054, 95% CI 1.18-2.6), previous thrombosis (P < 0.0001, 95% CI 1.58-4.52) and the presence of at least one cardiovascular risk factor (P = 0.036, 95% CI 1.15-3.13). Patients with a previous thrombosis occurred ≥24 months before ET diagnosis had a shorter TFS compared to patients with a previous thrombosis occurred <24 months (P = 0.0029, 95% CI 1.5-6.1); furthermore, patients with previous thrombosis occurred <24 months did not show a shorter TFS compared with patients without previous thrombosis (P = 0.303, 95% CI 0.64-3
