Meiotic drive in chronic lymphocytic leukemia compared with other malignant blood disorders. Sci Rep 2022; 12:6138. [PMID: 35413962 PMCID: PMC9005523 DOI: 10.1038/s41598-022-09602-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Accepted: 03/22/2022] [Indexed: 11/12/2022] Open
Abstract
The heredity of the malignant blood disorders, leukemias, lymphomas and myeloma, has so far been largely unknown. The present study comprises genealogical investigations of one hundred and twelve Scandinavian families with unrelated parents and two or more cases of malignant blood disease. For comparison, one large family with related family members and three hundred and forty-one cases of malignant blood disease from the Faroese population was included. The inheritance is non-Mendelian, a combination of genomic parental imprinting and feto-maternal microchimerism. There is significantly more segregation in maternal than in paternal lines, predominance of mother-daughter combinations in maternal lines, and father-son combinations in paternal lines. Chronic lymphocytic leukemia is the most frequent diagnosis in the family material, and chronic lymphocytic leukemia has a transgenerational segregation that is unique in that inheritance of susceptibility to chronic lymphocytic leukemia is predominant in males of paternal lines. Male offspring with chronic lymphocytic leukemia in paternal lines have a birth-order effect, which is manifest by the fact that there are significantly more male patients late in the sibling line. In addition, there is contravariation in chronic lymphocytic leukemia, i.e. lower occurrence than expected in relation to other diagnoses, interpreted in such a way that chronic lymphocytic leukemia remains isolated in the pedigree in relation to other diagnoses of malignant blood disease. Another non-Mendelian function appears in the form of anticipation, i.e. increased intensity of malignancy down through the generations and a lower age at onset of disease than otherwise seen in cases from the Cancer Registers, in acute lymphoblastic leukemia, for example. It is discussed that this non-Mendelian segregation seems to spread the susceptibility genes depending on the gender of the parents and not equally to all children in the sibling line, with some remaining unaffected by susceptibility i.e. "healthy and unaffected", due to a birth order effect. In addition, anticipation is regarded as a non-Mendelian mechanism that can amplify, «preserve» these vital susceptibility genes in the family. Perhaps this segregation also results in a sorting of the susceptibility, as the percentage of follicular lymphoma and diffuse large B-cell lymphoma is lower in the family material than in an unselected material. Although leukemias, lymphomas and myelomas are potentially fatal diseases, this non-Mendelian distribution and amplification hardly play any quantitative role in the survival of Homo sapiens, because these diseases mostly occur after fertile age.

Chronic Lymphocytic Leukemia (CLL): Biology and Therapy. Cancer Treat Res 2021.

Abstract
Chronic lymphocytic leukemia (CLL), the most common leukemia in the western world, is characterized by the accumulation of monoclonal B-lymphocytes in the bone marrow and lymphoid organs. Signaling via the B-cell receptor and Bruton tyrosine kinase (BTK) as well as resistance to apoptosis mediated by Bcl-2 are hallmarks of CLL biology and have been exploited in recent years to revolutionize management. As a result of the development of novel therapies, most CLL patients now can be spared conventional chemotherapy and can be treated using highly effective regimens consisting of BTK inhibitors, the Bcl-2 inhibitor venetoclax, and anti -CD20 monoclonal antibodies. The impact of novel therapies is particularly pronounced for high-risk cases including those with TP53 deletions/mutations who previously had a dismal outcome with conventional chemoimmunotherapy. Allogeneic HCT is a potentially curative option for selected younger patients with multiply relapsed high-risk disease.

Abstract
BACKGROUND Familial clustering of lymphoid and/or hematological malignancies (FHM) provides an opportunity to study the responsible genes. The data is limited in patients with lymphoid and hematological malignancies. METHODS The lymphoma database was used to identify patients seen in our institution from 1998 to 2019 with nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL). We studied FHM by collecting detailed history of any malignancy in the family (FM). RESULTS Two hundred NLPHL patients were identified. Contacting was not possible in 30 patients due to no response to the phone calls (22) and death [1]. 170/200 patients were interviewed; represented 167 families (3 patients with a family member with NLPHL). These 170 patients provided information about 8225 family members. These 167 families had a total of 329 family members with 334 malignancies (including 167 NLPHL patients and 5 members with 2 malignancies each). Of these 167 patients, 77 (46.1%) had no FM while 90 (53.9%) patients had a positive FM; 162 family members with 167 malignancies. Among these 167 families, 31 families (18.6%) had members with FHM +/- solid cancers. These 31 families had 35 family members (25 males:10 females) with 16 lymphomas: diffuse large B cell lymphoma [2], follicular center cell lymphoma [3], chronic lymphocytic leukemia/small lymphocytic lymphoma [3], non-Hodgkin lymphoma [2], classical HL [2], and NLPHL [4]. Total of 8 leukemia: acute lymphoblastic leukemia [4], acute myeloid leukemia [3], and leukemia - no subtyping [5]. These 35 FHM members are 1st [6], 2nd (16), and 3rd [7] degree relatives of 31 NLPHL patients. There are 4 families with NLPHL in family members; all these 8 NLPHL patients are male and are alive. The median total number of 1st + 2nd +3rd degree members are 81. The decrease in the age of diagnosis from 1st generation to the 2nd generation (anticipation) was noted in 13/17 patients; 2nd generation median age at diagnosis was 29.7 years vs 1st generation age 53 years (developed malignancy 23.3 years earlier). CONCLUSION FHM is frequent in NLPHL. This study provided us many important insights for planning future studies in terms of interviewing technique, time, and resource allocation and genetic testing.

Abstract
INTRODUCTION An estimated 30.000 breast implants are placed in the Netherlands annually. An increasing amount of reports have linked implants to the rare anaplastic large cell lymphoma (ALCL). Other implant-related lymphomas, such as those of B-cell lineage, are much rarer. PRESENTATION OF CASE A 62-year-old female presented with pain and Baker grade III capsular contraction of the right breast. Subpectorally placed textured anatomical implants had been in situ for 26 years after cosmetic augmentation. Magnetic Resonance Imaging (MRI) showed bilateral implant leakage. Explantation of both implants confirmed bilateral leakage after which symptoms went into remission. Three months later our patient noticed an erythematous area, scar swelling and serous fluid leakage on the lateral side of the inframammary fold of the right breast. Siliconomas were excised bilaterally together with a partial capsulectomy on the left. Histopathology and immunohistochemical analysis showed monotonous small cell B-lymphocytic infiltration (CD20+, CD5+, CD23+, ALK-) in both capsules, highly suggestive for chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). DISCUSSION CLL/SLL are classified as nearly the same disease. The primary difference is the localization; CLL is found the bone marrow and blood whereas SLL is predominantly in the lymph nodes and spleen. There are no previous descriptions of bilateral CLL/SLL found in periprosthetic capsules. CONCLUSION Breast implants are increasingly linked to various malignancies. In most cases, including our patient, implant explantation together with long-term follow-up suffices. MRI yields additional value in early stage diagnosis. More research is required to further optimize multidisciplinary care and improve patient outcomes.

Abstract
AIMS This is a nation-wide survey of chronic lymphocytic leukemia (CLL) patients at six large hematology centers in the Czech Republic. The aim was to identify specific populations, social, and health characteristics of CLL subgroups divided according to the immunogenetic features of their B cell receptors (BCRs) and clonality. PATIENTS AND METHODS Questionnaires directed to specific health, social, and environmental conditions were collected in a cohort of 573 CLL patients. For these patients, immunoglobulin heavy chain gene rearrangements were also analyzed in order to gain information about their clonality, IGHV mutational status, and the presence of stereotyped BCRs. Data extracted from the questionnaires were analyzed statistically in the context of immunogenetic features of the cohort. RESULTS There were no statistically significant differences in the data collected in the survey between patients with mutated and patients with unmutated IGHV. However, patients with oligoclonal CLL reported health conditions such as hypercholesterolemia, hypertension, herpes simplex, tumors, and also, separately, CLL in 1st degree relatives, more often than their monoclonal counterparts. In patients with stereotyped BCRs, we found more frequent alcohol consumption and gastric infections in subset #1 cases and frequent cholecystectomies and familial CLL in subset #2 cases. CONCLUSION To the best of our knowledge, this study is the first to investigate CLL immunogenetic features and clonality in the context of epidemiological data. We reported statistically significant associations suggesting the influence of certain health and social conditions on a number of clonal populations expanding in CLL and also on characteristic BCR features, especially stereotypy.

Abstract
PURPOSE OF REVIEW While chemoimmunotherapy has improved outcomes in chronic lymphocytic leukemia (CLL), it is not curative, has significant relapse rates, and is not always well tolerated. Recently, novel targeted therapies have been developed to increase response rates and reduce toxicity, especially in high-risk disease. Current goals of CLL therapies are to produce deep and durable, especially minimal residual disease (MRD)-negative, remissions so as to allow patients to ultimately discontinue treatment for a while. Whether this can be achieved with single agents or combination regimens is being investigated. Here, we comment on what the results of recent and ongoing clinical trials mean for the future of CLL therapy. RECENT FINDINGS Large trials have proven the efficacy of novel therapies including small-molecule inhibitors like ibrutinib, idelalisib, and venetoclax. These agents are approved as monotherapy for first-line treatment and/or in the relapsed/refractory setting. However, it appears that combining these drugs with other novel agents or with chemoimmunotherapy can give higher rates of MRD-negative remission, and delay disease resistance. Chimeric antigen receptor-T cells may change the outlook for patients with heavily refractory CLL. Further research will determine which drug combinations are optimal for the various subgroups of CLL patients.

Abstract
The co-occurrence of different types of hemo-lymphopoietic malignancies within a family provides clues about the pattern of inheritance and common environmental risk factors. A family presented with developing hemo-lymphopoietic cancers in three female first-degree relatives: a mother and her daughters. Case 1 was diagnosed with Walden Strom's macroglobulinemia at age 57. Case 2 and 3 presented with chronic myelogenous leukemia at age 32 and diffuse large B-cell lymphoma at age 28, respectively. There were not any significant common environmental risk factors in this family, but all three cases suffered from skin dermatitis and one of them, who suffered from chronic myelogenous leukemia, was diagnosed with morphea. This family had a sedentary and stressful lifestyle. Genetic is the foundation of some familial aggregation of cancers. Common lifestyle habits and environmental etiologies are important. Morphea as an autoimmune disease could have the essential role in developing hematolymphoid malignancies.

Abstract
The epidemiology of Hodgkin lymphoma (HL) has always been a source of fascination to researchers due to its heterogeneous characteristics of presentation. HL is an uncommon neoplasm of B-cell origin with an incidence that varies significantly by age, sex, ethnicity, geographic location and socioeconomic status. This complex pattern was also found to be replicated among Mediterranean basin populations. HL incidence rates progressively decreased from industrialized European countries such as France (ASR=2.61) and Italy (ASR=2.39) to less developed nations such as Albania (ASR=1.34) and Bosnia Herzegovina (ASR=1.1). Regarding HL mortality we have found that countries with the lowest incidence rates show the highest number of deaths from this cancer and viceversa. Finally, a wide gap in terms of survival was showed across the Mediterranean basin with survival rates ranged from 82.3% and 85.1% among Italian men and women, to 53.3 % and 59.3% among Libyan men and women, respectively. Factors such as the degree of socio-economic development, the exposure to risk factors westernization-related, the availability of diagnostic practices along with different genetic susceptibilities to HL may explain its variation across Mediterranean countries. Furthermore, the lack of health resources decisively contribute to the poor prognosis recorded in less developed region. In the future, the introduction of appropriate and accessible treatment facilities along with an adequate number of clinical specialists in the treatment of HL and other cancers are warranted in order to improve the outcomes of affected patients and treat a largely curable type of cancer in disadvantaged regions.

Abstract
Chronic lymphocytic leukemia (CLL) is the most common leukemia in the United States and one of the most heritable cancers. A family history of the disease is perhaps the best defined risk factor, and approximately 15-20% of CLL patients have a family member with CLL or a related lymphoproliferative disorder. Much effort has been devoted to trying to elucidate the mechanisms underlying this genetic risk. Familial CLL appears to be clinically and biologically similar to sporadic CLL, and most if not all CLL appears to be preceded by monoclonal B-cell lymphocytosis (MBL), which does appear to occur at higher frequency in relatives in families with CLL. Neither linkage studies nor candidate gene association studies have proven particularly informative in CLL, but genomewide association studies have identified multiple low-risk variants that together explain about 16% of the familial risk of CLL. Studies of individual families have identified higher-risk single nucleotide polymorphisms or copy number variants associated with disease risk in those families. Current efforts to identify additional risk loci are focused on applying next-generation sequencing to the germline of informative CLL families as well as individuals with sporadic CLL.

Abstract
UNLABELLED Familial disease is common in Waldenström macroglobulinemia (WM). We examined the impact of familial disease status on treatment outcome in WM and observed that familial disease was associated with inferior outcomes. However patients with familial WM receiving a bortezomib-containing regimen showed improved treatment outcomes vs. those receiving non–bortezomib-containing regimens. Bortezomib-containing regimens may therefore represent a more optimal treatment approach for patients with familial WM. BACKGROUND We examined the impact of familial predisposition on treatment outcome in 135 patients with Waldenström macroglobulinemia (WM), 26.7% of whom had first- or second-degree relatives with a B-cell lymphoproliferative disorder. PATIENTS AND METHODS All patients were rituximab naive and received a rituximab-containing regimen. There were no significant differences in baseline characteristics between cohorts. RESULTS Overall response (93.9% vs. 75.0%; P = .029) and complete response/very good partial response (CR/VGPR) (23.2% vs. 16.7%; P < .0001), time to progression (TTP) (45.5 vs. 21 months; P = .015) and time to next therapy (TTNT) (50.0 vs. 33.0 months; P = .024) favored patients with sporadic WM. By multivariate analysis, familial predisposition was an independent marker for disease progression (hazard ratio, 0.554). Patients with familial but not sporadic disease exhibited better responses, including CR/VGPR attainment (P = .0006) and a trend for longer progression-free survival (> 33 vs. 20.6 months; P = .08), with bortezomib-containing therapy. CONCLUSION The findings convey that familial predisposition is an important determinant of treatment outcome in WM. Prospective studies to confirm these observations are needed.

Abstract
A 21-year-old man presented to hospital with a two-month history of productive cough with no other symptoms. Radiology revealed a cavitating lesion in the left upper lobe for which a variety of diagnoses were considered. A biopsy revealed primary pulmonary Hodgkin's lymphoma. Primary pulmonary Hodgkin's lymphoma is an uncommon initial presentation; lung lesions usually occur later in the course of the disease. Following diagnosis, the patient began chemotherapy and full remission was achieved.

Abstract
Mutations in the IL-2-inducible T-cell kinase gene have recently been shown to cause an autosomal recessive fatal Epstein Barr virus (EBV) associated lymphoproliferation. We report 3 cases from a single family who presented with EBV-positive B-cell proliferation diagnosed as Hodgkin's lymphoma. Single nucleotide polymorphism array-based genome-wide linkage analysis revealed IL-2-inducible T-cell kinase as a candidate gene for this disorder. All 3 patients harbored the same novel homozygous nonsense mutation C1764G which causes a premature stop-codon in the kinase domain. All cases were initially treated with chemotherapy. One patient remains in durable remission, the second patient subsequently developed severe hemophagocytic lymphohistiocytosis with multi-organ failure and died, and the third patient underwent a successful allogeneic bone marrow transplantation. IL-2-inducible T-cell kinase deficiency underlies a new primary immune deficiency which may account for part of the spectrum of Epstein Barr virus related lymphoproliferative disorders which can be successfully corrected by bone marrow transplantation.

Abstract
Approximately 10% of patients with chronic lymphocytic leukaemia (CLL) have a family history of the disease or a related lymphoproliferative disorder, yet the relationship of familial CLL to genomic abnormalities has not been characterized in detail. We therefore studied 75 CLL patients, half familial and half sporadic, using high-resolution array comparative genomic hybridization (CGH), in order to better define the relationship of genomic abnormalities to familial disease and other biological prognostic factors. Our results showed that the most common high-risk deletion in CLL, deletion 11q, was significantly associated with sporadic disease. Comparison of familial to sporadic disease additionally identified a copy number variant region near the centromere on 14q, proximal to IGH@, in which gains were associated both with familial CLL, and with mutated IGHV and homozygous deletion of 13q. Homozygous deletion of 13q was also found to be associated with mutated IGHV and low expression of ZAP-70, and a significantly longer time to first treatment compared to heterozygous deletion or lack of alteration. This study is the first high resolution effort to investigate and report somatic genetic differences between familial and sporadic CLL.

Abstract
Though B-chronic lymphocytic leukemia (CLL) is known to be a heterogeneous disease, only recently has the familial component of CLL been more thoroughly investigated. This entity is seen in approximately 5%-10% of all patients with CLL and can be associated with earlier age of diagnosis, higher female prevalence, and increased incidence of other lymphoproliferative disorders (LPDs), such as non-Hodgkin lymphoma and the more recently described monoclonal B-cell lymphocytosis CLL in family members. The prognostic parameters and clinical course of familial CLL is not clearly distinguishable from that of sporadic disease. In addition, it is not clear that the treatment responses for progressive disease has any discernible difference in familial versus sporadic CLL. The genetic etiology of CLL is unknown, and early work on familial CLL has not yet uncovered any obvious gene or group of genes that can be clearly related to the pathophysiology of CLL. However, the detailed genetic study of familial CLL is likely to be critical in uncovering relevant genes. At present it is best to indicate to concerned CLL patients that their relatives are at relatively low risk of developing CLL or other LPDs.
