Psychosocial adaptation of families with children newly diagnosed with cancer in the Greek population amidst the socioeconomic crisis.

OBJECTIVE: To present the initial assessment of psychosocial adaptation among Greek parents whose children were newly diagnosed with cancer amidst the turmoil of an ongoing financial crisis. STUDY DESIGN: This prospective observational study used a quantitative approach. PARTICIPANTS: Sixty-one parents of children with cancer treated at a large urban tertiary-care children's hospital were prospectively recruited to participate in our study during the first week of their child's diagnosis (2013-2016). METHODS: The parents were asked to complete the psychosocial assessment tool (PAT 2.0), Zung Depression Scale, State-Trait Anxiety Inventory, Hospital Anxiety and Depression Scale, and World Health Organization Quality of Life-Bref Instrument; Moreover, three female healthcare providers (the physician oncologist, the head nurse and a senior nurse) completed the relevant PAT 2.0 -Staff Perceptions questionnaire the results of which were then compared to those of the child's parent. FINDINGS: The majority of parents had PAT 2.0 scores indicative of increased psychosocial risk :54% were stratified into the "Targeted" (moderate risk) and 15% into the "Clinical" (highest risk) categories, whereas healthcare providers underestimated psychosocial risk in 57%-59% of the cases. The subscales that most contributed to the increased scores were Parental Stress Reaction, Family Structure and Resources, and Family Social Support. The PAT 2.0 had statistically significant correlations with most of the anxiety and depression scales, with Zung having the strongest correlation (r-value: +0.5, p-value <0.01). Our cohort presented more anxiety and depression compared to the general Greek population (14% for depression versus 2,9% for the general population and 46% for anxiety compared to 4,1%) in the years of financial recession in Greece. CONCLUSIONS: The parents of children newly diagnosed with cancer in Greece are at increased risk for developing anxiety and depression in the years of financial recession in Greece compared to general population. IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS: Parental stress reaction to diagnosis as well as lack of family resources and social support may contribute to this difference. Screening for psychosocial risk factors is essential for the early identification of these families and for the optimal utilization of the limited available resources in times of economic hardship.

Aplastic anemia and paroxysmal nocturnal hemoglobinuria in children and adults in two centers of Northern Greece.

Bone marrow failure (BMF) syndromes are a group of various hematological diseases with cytopenia as a main common characteristic. Given their rarity and continuous progress in the field, we aim to provide data considering the efficiency and safety of the therapeutic methods, focusing on the treatment of aplastic anemia(AA) and paroxysmal nocturnal hemoglobinuria (PNH). We enrolled consecutive patients diagnosed with BMF in two referral centers of Northern Greece from 2008 to 2020. We studied 43 patients with AA (37 adults and 6 children/adolescents) and 6 with classical PNH. Regarding classical PNH, 4 patients have received eculizumab treatment with 1/4 presenting extravascular hemolysis. Among 43 patients with aplastic anemia, PNH clones were detected in 11. Regarding patients that did not receive alloHCT (n=15), 14/15 were treated with ATG and cyclosporine as first line, with the addition of eltrombopag in patients treated after its approval (n=9). With a median follow-up of 16.7 (1.8-56.2) months from diagnosis, 12/14 (85.7%) are alive (4-year OS: 85.1%). AlloHCT was performed in 28 patients. Five patients developed TA-TMA which did not resolve in 3/5 (all with a pre-transplant PNH clone). With the follow-up among survivors reaching 86.3 (6.3-262.4) months, 10-year OS was 56.9%, independently associated with PNH clones after adjusting for age (p=0.024). In conclusion, our real-world experience confirms that novel treatments are changing the field of BMF syndromes. Nevertheless, there is still an unmet need to personalize algorithms in this field.

Adolescents and young adults (AYA) with acute myeloid leukemia (AML): real-world long-term results and age-specific outcomes.

Opposing acute lymphoblastic leukemia, sparse data about AYAs with acute myeloid leukemia (AML) is available. Overall, 125 AYAs (age 10-35 years) treated during the last two decades were evaluated and compared to 385 older patients. CBF leukemia was more frequent in AYAs (21.6% vs. 8%, p < 0.001); however, many presented high-risk features. AYAs showed improved complete remission rate (CR, 80% vs. 65%, p = 0.01), lower cumulative incidence of relapse and TRM and longer survival (5 year-OS 53% vs. 24%, p < 0.0001), observed mainly in intermediate-risk karyotype. Adolescents displayed even better outcomes (5 year-OS 69%). AlloHCT in CR1 was beneficial for nonadolescent AYAs (5 year-OS 66.7% vs. 44.4% without HCT, p = 0.04). Among 50 APL patients, 19 AYAs experienced better outcomes than older, mainly attributed to reduced treatment-related mortality (TRM, 5% vs. 19%, p = 0.1). We observed an important (>10%) survival gain for AYAs during the last decade. However, AYAs have still unmet needs to obtain optimal cure rates.

Cytogenetics in Chronic Lymphocytic Leukemia: ERIC Perspectives and Recommendations.

Mounting evidence underscores the clinical value of cytogenetic analysis in chronic lymphocytic leukemia (CLL), particularly as it allows the identification of complex karyotype, that has recently emerged as a prognostic and potentially predictive biomarker. That said, explicit recommendations regarding the methodology and clinical interpretation of either chromosome banding analysis (CBA) or chromosome microarray analysis (CMA) are still lacking. We herein present the consensus of the Cytogenetic Steering Scientific Committee of ERIC, the European Research Initiative on CLL, regarding methodological issues as well as clinical interpretation of CBA/CMA and discuss their relevance in CLL. ERIC considers CBA standardized and feasible for CLL on the condition that standards are met, extending from the use of novel mitogens to the accurate interpretation of the findings. On the other hand, CMA, is also standardized, however, robust data on its clinical utility are still scarce. In conclusion, cytogenetic analysis is not yet mature enough to guide treatment choices in CLL. That notwithstanding, ERIC encourages the wide application of CBA, and potentially also CMA, in clinical trials in order to obtain robust evidence regarding the predictive value of specific cytogenetic profiles towards refining risk stratification and improving the management of patients with CLL.

Secondary Acute Myeloid Leukemia (sAML): Similarly Dismal Outcomes of AML After an Antecedent Hematologic Disorder and Therapy Related AML.

Therapy related acute myeloid leukemia (tAML) and secondary AML after an antecedent hematologic disorder (sAML-AHD) are often addressed together, blurring any clinical and prognostic differences. Among 516 AML patients, we compared characteristics and outcomes of 149 patients with "sAML" (sAML-AHD: 104, tAML: 45), uniformly and intensively treated during the last 2 decades at 1 center. Clinical outcomes of the whole "sAML" cohort were significantly inferior compared to de novo AML and in both intermediate and poor cytogenetic risk groups. Adverse karyotype had no effect on survival in tAML, while it was a negative predictor in sAML-AHD. Both groups showed similarly dismal outcome, with low complete remission rates (CR 44% vs. 41%) and median overall survival (OS 7 vs. 10.5 months). Allogeneic hematopoietic cell transplantation (alloHCT) recipients in CR1 had superior median OS (24 vs. 8 months). By multivariate analysis, alloHCT was an independent predictor of outcome, while karyotype was for sAML-AHD only. In conclusion, both "sAML" groups have inferior outcomes after chemotherapy, with adverse karyotype affecting primarily sAML-AHD. Until new treatment approaches are available, only alloHCT offers a survival advantage.

Survival Advantage of Treosulfan Plus Fludarabine Before Allogeneic Hematopoietic Cell Transplantation for Older or Comorbid Patients With Myeloid Malignancies.

We have previously shown an advantage of a myeloablative conditioning regimen with reduced toxicity (Fludarabine 150 mg/m2, Treosulfan 42 g/m2, FluTreo) compared to a reduced-intensity regimen. We aimed to determine long-term safety and efficacy of FluTreo. We prospectively studied consecutive patients who received FluTreo in our center (2014-2019) on the basis of age (≥50 years), hematopoietic cell transplantation comorbidity index (HCT-CI) ≥2, or both. FluTreo recipients were then compared to a historical control group. We studied 68 FluTreo recipients, with a median age of 58.5 years and HCT-CI of 3. We calculated cumulative incidence (CI) of acute (grade 2-4) and moderate/severe chronic graft-versus-host disease (GVHD) (29.9% and 25%, respectively). The 3-year CI of treatment-related mortality was 19.1%, associated only with acute GVHD (P < .001). With a median follow-up of 27.3 (range 5.7-84.5) months in surviving patients, the 3-year overall survival (OS) was 56.6%, and disease-free survival (DFS) was 54.9%. Median survival has not yet been reached. Among pretransplantation and transplantation factors, only HCT-CI was associated with DFS and OS (P = .022 and P = .043, respectively). FluTreo recipients aged ≥50 with HCT-CI ≤ 2 had favorable DFS and OS compared with patients aged ≥50 with HCT-CI ≤2 after myeloablative conditioning. Our real-world study confirms that HCT with FluTreo expands the transplant population with favorable outcomes compared to previously used conditions. The choice of HCT in patients of a rather older age and comorbidity index needs to be revisited.

Enhanced HbF reactivation by multiplex mutagenesis of thalassemic CD34+ cells in vitro and in vivo.

Thalassemia or sickle cell patients with hereditary persistence of fetal hemoglobin (HbF) have an ameliorated clinical phenotype and, in some cases, can achieve transfusion independence. Inactivation via genome editing of γ-globin developmental suppressors, such as BCL11A or LRF/ZBTB7A, or of their binding sites, have been shown to significantly increase expression of endogenous HbF. To broaden the therapeutic window beyond a single-editing approach, we have explored combinations of cis- and trans-editing targets to enhance HbF reactivation. Multiplex mutagenesis in adult CD34+ cells was well tolerated and did not lead to any detectable defect in the cells' proliferation and differentiation, either in vitro or in vivo. The combination of 1 trans and 1 cis mutation resulted in high editing retention in vivo, coupled with almost pancellular HbF expression in NBSGW mice. The greater in vivo performance of this combination was also recapitulated using a novel helper-dependent adenoviral-CRISPR vector (HD-Ad-dualCRISPR) in CD34+ cells from ß-thalassemia patients transplanted to NBSGW mice. A pronounced increase in HbF expression was observed in human red blood cells in mice with established predominant ß0/ß0-thalassemic hemopoiesis after in vivo injection of the HD-Ad-dualCRISPR vector. Collectively, our data suggest that the combination of cis and trans fetal globin reactivation mutations has the potential to significantly increase HbF both totally and on a per cell basis over single editing and could thus provide significant clinical benefit to patients with severe ß-globin phenotype.

Paroxysmal nocturnal hemoglobinuria and myelodysplastic syndrome: Disappearance of cytogenetic abnormalities.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare life-threatening disease resulting from clonal hematopoietic stem cell evolution. There is a strong link between PNH and other acquired bone marrow failure syndromes, including myelodysplastic syndrome (MDS). Cytogenetic, morphological abnormalities or both are observed in the range of MDS/PNH diagnosis. Herein, we investigate cytogenetic abnormalities in PNH patients. We found two patients with PNH clones and MDS-associated abnormalities that later disappeared. The first patient, originally diagnosed with MDS and Trisomy 6, developed a large PNH clone. At the time of PNH diagnosis, the abnormal cytogenetic clone was no longer detectable despite persistent trilineage dysplasia. In the second patient, a large PNH clone and MDS-defining abnormality were detected at diagnosis, without evidence of dysplasia. No cytogenetic abnormalities were evident after complement inhibition. Our report adds significant information on the complex link between MDS and PNH, suggesting that distinction between these entities may be difficult in some cases. Especially in transplant eligible patients, the clinical phenotype may be the leading feature for treatment decisions in the era of complement inhibition. Lastly, the transient presence of cytogenetic abnormalities is a unique characteristic of our patients' course that needs to be further elucidated in larger studies.

Cytogenetic complexity in chronic lymphocytic leukemia: definitions, associations, and clinical impact.

Recent evidence suggests that complex karyotype (CK) defined by the presence of ≥3 chromosomal aberrations (structural and/or numerical) identified by using chromosome-banding analysis (CBA) may be relevant for treatment decision-making in chronic lymphocytic leukemia (CLL). However, many challenges toward the routine clinical application of CBA remain. In a retrospective study of 5290 patients with available CBA data, we explored both clinicobiological associations and the clinical impact of CK in CLL. We found that patients with ≥5 abnormalities, defined as high-CK, exhibit uniformly dismal clinical outcomes, independently of clinical stage, TP53 aberrations (deletion of chromosome 17p and/or TP53 mutations [TP53abs]), and the expression of somatically hypermutated (M-CLL) or unmutated immunoglobulin heavy variable genes. Thus, they contrasted with CK cases with 3 or 4 aberrations (low-CK and intermediate-CK, respectively) who followed aggressive disease courses only in the presence of TP53abs. At the other end of the spectrum, patients with CK and +12,+19 displayed an exceptionally indolent profile. Building upon CK, TP53abs, and immunoglobulin heavy variable gene somatic hypermutation status, we propose a novel hierarchical model in which patients with high-CK exhibit the worst prognosis, whereas those with mutated CLL lacking CK or TP53abs, as well as CK with +12,+19, show the longest overall survival. Thus, CK should not be axiomatically considered unfavorable in CLL, representing a heterogeneous group with variable clinical behavior. High-CK with ≥5 chromosomal aberrations emerges as prognostically adverse, independent of other biomarkers. Prospective clinical validation is warranted before ultimately incorporating high-CK in risk stratification of CLL.

Long-term outcomes of total body irradiation plus cyclophosphamide versus busulfan plus cyclophosphamide as conditioning regimen for acute lymphoblastic leukemia: a comparative study.

The role of total body irradiation (TBI) in allogeneic hematopoietic stem cell transplantation (HCT) for adult acute lymphoblastic leukemia (ALL) remains controversial. Therefore, we investigated long-term treatment outcomes of transplanted ALL patients aiming to identify prognostic factors and the impact of conditioning. We enrolled consecutive ALL patients transplanted from 1990 to 2016, following TBI- or busulfan (Bu)-based conditioning regimen. We studied 151 ALL patients transplanted in first complete remission (CR) (60), other CR (33), or relapsed/refractory disease (58) from sibling (87), and HLA-matched (42) or mismatched (17) unrelated and alternative donors (5). High-dose fractionated TBI-based conditioning was administered in 84. No differences were observed in baseline characteristics, except for disease stage at transplant, donor type, and graft source. With a follow-up of 19.0 (0.5-170.5) in TBI and 14.5 (1.2-319.1) months in non-TBI patients, there was no difference in acute (grades II-IV) or chronic GVHD, thrombotic microangiopathy, and bacterial or fungal infections. Only viral infections were significantly increased in the non-TBI group. There was no significant difference in the cumulative incidence (CI) of treatment-related or relapse mortality and disease-free or overall survival (OS). In the multivariate analysis, unfavorable pre-transplant predictors of OS were age (p = 0.024), advanced disease stage (p = 0.007), and female-to-male donor (p = 0.006). Interestingly, TBI patients younger than 40 years had significantly higher OS (55.1%, p = 0.023) and DFS (48.6%, p = 0.020). In conclusion, high-dose TBI is feasible in younger patients providing better survival. The choice between TBI- or Bu-conditioning regimens remains challenging.

EGFR or PD-L1 decision for first line therapy in a case series of EGFR positive and PD-L1 >50.

Targeted therapies are on the market for the past five years and recently pembrolizumab was approved as first line treatment for patients with PD-L1 >50%. We present three cases of patients which had epidermal growth factor receptor positive expression and programmed death-ligand 1 (PD-L1), PD-L1 >50% overexpression.

"Liquid elbows" due to afatinib administration.

Non-small cell lung cancer adenocarcinoma in the past decade has targeted therapies as the cornerstone for therapy. In specific patients with epidermal growth factor receptor mutation have three different therapy approaches with the tyrosine kinase inhibitors: erlotinib, gefitinib and afatinib. Nowadays we can use tyrosine kinase inhibitors as second line treatment for squamous cell carcinoma. We present a case with a patient with squamous cell carcinoma receiving afatinib tyrosine kinase inhibitor who presented elbow bursitis or olecranon bursitis in both elbows.

Possible adverse effects of immunotherapy in non-small cell lung cancer; treatment and follow-up of three cases.

In the past decade novel agents are on the market for non-small cell lung cancer adenocarcinoma based on pharmacogenomics. The epidermal growth factor receptor mutation, anaplastic lymphoma kinase and programmed death-ligand 1 investigation is necessary in the everyday clinical practice for the oncologic patient. Immunotherapy is nowadays the novel therapy for advanced stage non-small cell lung cancer with two agents nivolumab and pembrolizumab. In the current case series we will present adverse effects from our centers and comment on the treatment and follow-up of the patients.

Re-biopsy after relapse of targeted therapy. T790M after epidermal growth factor mutation, where and why based on a case series.

Guidelines for the treatment of non-small cell lung cancer adenocarcinoma positive in epidermal growth factor mutations indicate tyrosine kinase inhibitors. There are currently three tyrosine kinase inhibitors that can be used as first line treatment: gefitinib, erlotinib and afatinib. Regarding erlotinib and afatinib dosage can be modified in the case of severe adverse effects. In the case of disease relapse investigation for T790M mutation has to be made either with re-biopsy or liquid biopsy and osimertinib has to be administered when T790M is diagnosed. Based on a case series we indicate which is the best approach for T790M mutation.

Survival Advantage and Comparable Toxicity in Reduced-Toxicity Treosulfan-Based versus Reduced-Intensity Busulfan-Based Conditioning Regimen in Myelodysplastic Syndrome and Acute Myeloid Leukemia Patients after Allogeneic Hematopoietic Cell Transplantation.

Treosulfan has been incorporated in conditioning regimens for sustained remission without substantial toxicity and treatment-related mortality (TRM). We aimed to analyze the safety and efficacy of a fludarabine 150 mg/m2 and treosulfan 42 g/m2 (FluTreo) conditioning regimen in medically infirm patients. Outcomes were compared with those of a similar historical group treated with fludarabine 150 mg/m2 to 180 mg/m2, busulfan 6.4 mg/kg, and antithymocyte globulin (ATG) 5 mg/kg to 7.5 mg/kg (FluBuATG). Thirty-one consecutive patients with acute myeloid leukemia (AML; n = 21), myelodysplastic syndrome (MDS; n = 6), or treatment-related AML (n = 4) received FluTreo conditioning. The historical group consisted of 26 consecutive patients treated with FluBuATG. In the FluTreo group, engraftment was prompt in all patients and 74% achieved >99% donor chimerism by day +30. No grades III or IV organ toxicities were noted. One-year cumulative incidences (CI) of acute and chronic graft-versus-host disease (GVHD) were 19.4% and 58.4%. The groups were similar for age, disease risk, lines of treatment, hematopoietic cell transplantation-specific comorbidity index, and acute or chronic GVHD incidence, except that there were more matched unrelated donor recipients in the FluTreo group (P < .001). With 20 (range, 2 to 36) months follow-up for FluTreo and 14 (range, 2 to 136) for FluBuATG, the 1-year cumulative overall survival (OS) probability was 76% versus 57%, respectively (P = .026); 1-year disease-free survival (DFS) was 79% versus 38% (P < .001). In multivariate analysis, the only significantly favorable factor for OS and DFS was FluTreo (P = .010 and P = .012). The CI of relapse mortality was markedly decreased in FluTreo versus FluBuATG (7.4% versus 42.3%, P < .001). In conclusion, the treosulfan-based regimen resulted in favorable OS and DFS with acceptable toxicity and low relapse rates compared with busulfan-based conditioning.

Karyotypic complexity rather than chromosome 8 abnormalities aggravates the outcome of chronic lymphocytic leukemia patients with TP53 aberrations.

Patients with chronic lymphocytic leukemia (CLL) harboring TP53 aberrations (TP53abs; chromosome 17p deletion and/or TP53 mutation) exhibit an unfavorable clinical outcome. Chromosome 8 abnormalities, namely losses of 8p (8p-) and gains of 8q (8q+) have been suggested to aggravate the outcome of patients with TP53abs. However, the reported series were small, thus hindering definitive conclusions. To gain insight into this issue, we assessed a series of 101 CLL patients harboring TP53 disruption. The frequency of 8p- and 8q+ was 14.7% and 17.8% respectively. Both were associated with a significantly (P < 0.05) higher incidence of a complex karyotype (CK, ≥3 abnormalities) detected by chromosome banding analysis (CBA) compared to cases with normal 8p (N-8p) and 8q (N-8q), respectively. In univariate analysis for 10-year overall survival (OS), 8p- (P = 0.002), 8q+ (P = 0.012) and CK (P = 0.009) were associated with shorter OS. However, in multivariate analysis only CK (HR = 2.47, P = 0.027) maintained independent significance, being associated with a dismal outcome regardless of chromosome 8 abnormalities. In conclusion, our results highlight the association of chromosome 8 abnormalities with CK amongst CLL patients with TP53abs, while also revealing that CK can further aggravate the prognosis of this aggressive subgroup.
