Abstract
Acute hemorrhagic leukoencephalitis (AHLE), is a rare inflammatory demyelinating disorder, variant of acute disseminated encephalomyelitis. The diagnosis of AHLE remains challenging due to the rarity of the disease and the lack of a reliable biomarker. We report here a case of a 73-year-old male patient with a progressive, low-grade febrile confusional syndrome 20 days after receiving the first dose of BNT162b2 vaccine against SARS-CoV-2. Evidence indicative of the underlying condition by an extensive panel of imaging (brain magnetic resonance imaging, computed tomography and digital subtraction angiography), laboratory (complete blood count, biochemistry, coagulation, tests for autoimmune or infectious disorders, tumor markers, hormonal levels, cerebrospinal fluid analysis) and electrodiagnostic tests were scarce, and mainly non-specific. Sequential neuroimaging revealed the appearance of extensive T2 lesions (signs of gliosis) along with multiple hemorrhagic lesions at various cortical sites. The patient was treated with corticosteroids, discontinued due to severe adverse effects, and subsequently with sessions of plasmapheresis and monthly intravenous administration of cyclophosphamide. Considering the rapid aggravation of the patient's neurological status, the MRI findings of cortical lesions and the lack of response to any treatment, a biopsy of a frontal lobe lesion was conducted, confirming the presence of confluent, inflammatory-edematous lesions with scattered areas of necrosis and hemorrhage, and ultimately areas of demyelination, thus confirming the diagnosis of AHLE. After more than 5 months of hospitalization the patient was transferred in a primary care facility and remained in a permanent vegetative state until his death, more than 2 years later.

Abstract
Non-Hodgkin lymphoma's (NHL) incidence is rising over time, and B cell lymphomas comprise the majority of lymphomas. The phosphoinositide 3-kinase (PI3K)/v-akt murine thymoma viral oncogene homologue 1 (Akt)/mammalian target of the rapamycin (mTOR) signaling pathway plays a critical role in a variety of cellular processes, such as cell proliferation and survival. Its role in lymphomagenesis is confirmed in many different types of B cell lymphomas. This review is mainly focused on the PI3K/v-akt/mTOR pathway-related oncogenic mechanisms in B cell NHLs with an emphasis on common B cell lymphoma types [diffuse large B cell lymphoma (DLBCL) and mantle cell lymphoma (MCL)]. Furthermore, it summarizes the literature regarding the clinical applications of the mTOR inhibitors temsirolimus and everolimus in B cell NHLs, which have been tested in a range of clinical trials enrolling patients with B cell malignancies, either as monotherapy or in combination with other agents or regimens.

Abstract
Chronic myelogenous leukemia at blast crisis with a T-cell phenotype (T-ALL CML-BC) at diagnosis, without any prior history of CML is extremely rare. After the introduction of tyrosine kinase inhibitors (TKIs), CML patients have a median survival comparable to general population and accelerated/blast crisis are rarely encountered. Most CML patients (80%) transform into acute myeloid leukemia and the rest into B-ALL. Anecdotal cases of Ph+ T-ALL, either de novo or in the context of CML-BC have been reported. Left shift in the blood, the presence of splenomegaly/extramedullary infiltration and the occurrence of BCR::ABL1 rearrangement in both the blastic population, as well as in the myeloid cell compartment are key points in differentiating de novo Ph+ T-ALL from T-ALL CML-BC. The latter is a rare entity, characterized by extramedullary disease, p210 transcript and clonal evolution. Lack of preceding CML does not rule out the diagnosis of T-ALL CML-BC. Prompt TKI treatment with ALL-directed therapy followed by allogeneic stem cell transplantation may offer long-term survival in this otherwise poor prognosis entity. In this paper, we describe a patient with T-ALL CML-BC at presentation, still alive 51 months after diagnosis and we offer a review of the literature on this rare subject. All clinical and laboratory features are provided in order to distinguish de novo Ph+ T-ALL from T-ALL CML-BC, underscoring the prognostic and therapeutic significance of such a differentiation.

Abstract
Multiple myeloma (MM) is the most common primary bone-originating tumor, whereas extramedullary plasmacytoma (EMP) is a plasma cell tumor that arises outside the bone and is most commonly found in the head and neck area. Gastrointestinal and particularly gallbladder involvement is exceedingly rare, and symptoms, if any are present, are usually similar to those seen with cholelithiasis. Treatment options usually include surgical resection and/or chemotherapy. In this report, we present a rare case of a clinically unexpected plasmablastic extramedullary plasmacytoma that was found on abdominal ultrasound (US) and magnetic resonance imaging (MRI) in a 61-year-old asymptomatic patient and led him to undergo cholecystectomy. A fluorodeoxyglucose positron emission computed tomography (FDG PET-CT) that was performed due to the onset of left thigh pain also demonstrated concurrent bone plasmacytoma. The patient is currently receiving chemotherapy and is also being prepared for autologous stem cell transplantation. In this context, we further present the diagnostic, therapeutic and prognostic challenges of EMPs. Lastly, we point out the distinct features of the plasmablastic subtype and analyze its differences compared to other histologic subtypes in achieving a successful diagnosis and management.

Abstract
Accumulating data shows that altered metabolic activity contributes to glioma development. Recently, modulation of SSADH (succinic semialdehyde dehydrogenase) expression, implicated in the catabolism of GABA neurotransmitter, was shown to impact glioma cell properties, such as proliferation, self-renewal and tumorigenicity. The purpose of this study was to investigate the clinical significance of SSADH expression in human gliomas. Using public single-cell RNA-sequencing data from glioma surgical resections, we initially grouped cancer cells according to ALDH5A1 (Aldehyde dehydrogenase 5 family member A1) expression, which encodes SSADH. Gene ontology enrichment analysis of genes differentially expressed between cancer cells expressing high or low levels of ALDH5A1, highlighted enrichment in genes implicated in cell morphogenesis and motility. In glioblastoma cell lines, ALDH5A1 knockdown inhibited cell proliferation, induced apoptosis and reduced their migratory potential. This was accompanied by a reduction in the mRNA levels of the adherens junction molecule ADAM-15 and deregulation in the expression of EMT biomarkers, with increased CDH1 and decreased vimentin mRNA levels. Evaluation of SSADH expression in a cohort of 95 gliomas using immunohistochemistry showed that SSADH expression was significantly elevated in cancer tissues compared to normal brain tissues, without any significant correlation with clinicopathological characteristics. In summary, our data show that SSADH is upregulated in glioma tissues irrespective of the histological grade and its expression sustains glioma cell motility.

Abstract
BACKGROUND Poromas, and their malignant counterparts, porocarcinomas, harbor recurrent translocations involving YAP1-MAML2, YAP1-NUTM1, and infrequently WWTR1-NUTM1; YAP1-NUTM1 being the most common in porocarcinomas. NUT immunohistochemistry (IHC) can be used to identify NUTM1-translocated tumors. This study sought to investigate potential novel NUTM1-fusion partners among NUT IHC-positive poromas and porocarcinomas. METHODS 13 NUT IHC-positive poroid tumors (4 poromas, 9 porocarcinomas) were identified within a multi-institutional international cohort. Next Generation Sequencing (NGS) assessed for NUTM1 fusion partners. RESULTS NGS detected a NUTM1 fusion in 12/13 cases: YAP1-NUTM1 (11/12 cases) and WWTR1-NUTM1 (1/12 cases). Two of the cases (2/12) with NUTM1 fusion were not called by the NGS algorithm but had at least one read spanning YAP1-NUTM1 breakpoints upon manual review. A NUTM1 fusion was not identified in one case, however, the sample had low RNA quality. The following fusion events were identified: YAP1 exon 4 :: NUTM1 exon 3 in six cases, YAP1 exon 6 :: NUTM1 exon 2 in one case, YAP1 exon 3 :: NUTM1 exon 3 in three cases, WWTR1 exon 3 :: NUTM1 exon 3 in one case and YAP1 exon 8 :: NUTM1 exon 3 fusion in one case. CONCLUSION While no novel NUTM1 fusion partners were identified within our cohort, twelve of thirteen cases had discoverable NUTM1 fusions; YAP1-NUTM1 fusion was detected in 11 cases (92%) and WWTR1-NUTM1 in 1 case (8%). These data corroborate findings from other recent investigations and further substantiate the utility of NUT IHC in diagnosing a subset of poroid neoplasms. Additionally, two of our cases harbored fusions of YAP1 exon 6 to NUTM1 exon 3 and YAP1 exon 8 to NUTM1 exon 2, which have not been reported before in poroid neoplasms and indicate novel break points of YAP1.

Abstract
PMLBCL is an uncommon thymic B-cell neoplasm accounting for about 2.5% of NHLs. Patients present with bulky mediastinal lymphadenopathy,causing dyspnea and dry cough. Extrathoracic distal extranodal sites is a rare event at disease presentation. This is a unique case of a young female patient with symptomatic, bulky ovarian tumor. PMLBCL was finally diagnosed with a clinically silent bulky mediastinal mass.
Primary mediastinal large B- cell lymphoma (PMLBCL) is a mature aggressive B-cell lymphoma which affects mainly young and middle-aged women. The majority of patients present with bulky mediastinal lymphadenopathy. Extranodal involvement is a rare phenomenon at disease presentation. Herein, we describe a case of a young female with PMLBCL presenting with symptomatic, bulky ovarian involvement. The 23-year old patient presented at the Emergency Department with abdominal pain. The chest X-ray film revealed a mediastinal mass and CT scan revealed a large pelvic mass, possibly involving the ovaries. Due to the development of signs of acute abdomen, she was urgently transferred to the operation room where surgical resection of the right ovary and the adjacent mass was performed. The histological examination of the resected material revealed proliferation of PMLBCL cells. This is the first report in the scientific literature describing symptomatic ovarian mass as the initial mode of presentation of PMLBCL.

Abstract
ABSTRACT A 42-year-old man presented with painless, left inguinal lymphadenopathy, which was suspicious of malignant lymphoma. Multiple left-sided foci of markedly increased metabolic activity were observed on PET/CT (SUVmax up to 22.3), located at the inguinal, iliac, and para-aortic lymph nodes along with small-sized right inguinal lymphadenopathy. Laboratory tests revealed increased inflammation markers and neutrophilic leukocytosis. Pathological examination from dissected inguinal lymph node was consistent with granulomatous disease. Infection by chlamydia trachomatis was made serologically establishing the diagnosis of lymphogranuloma venereum.

Abstract
Lymphoma is the second most common malignancy in the head and neck area, affecting both nodal and extranodal sites, including oral soft and hard tissues, usually in the form of non-Hodgkin’s lymphoma (NHL). However, lymphomas of the jaws, including diffuse large B-cell lymphoma (DLBCL), the most common type of NHL, are very rare and may cause significant diagnostic challenges resembling common jaw pathologies, such as periapical lesions, osteomyelitis and osteonecrosis.
The aim of this paper is to present a rare case of DLBCL in an 84-years-old diabetic male patient on methylprednisolone treatment for autoimmune hemolytic anemia. The lesion appeared clinically as exposed necrotic bone of the maxilla with surrounding soft tissue ulceration and radiographically as an extensive osteolytic lesion with ill-defined borders. Despite the resemblance of the lesion with osteonecrosis or osteomyelitis that could be theoretically related to diabetes and/or systemic use of corticosteroids, histopathologic examination, necessitating a repeat biopsy in order to acquire sufficient tissue, revealed the final diagnosis of lymphoma. The need for increased clinical awareness and vigilance of this possible diagnostic conundrum is emphasized. Key words:Diffuse large B-cell lymphoma, exposed bone, oral, malignancy, maxilla, jaw osteonecrosis, differential diagnosis.

Abstract
Surface bone sarcomas are rare malignant bone tumours. Osseous and cartilaginous surface bone sarcomas are the most common, with parosteal and periosteal osteosarcomas, periosteal chondrosarcomas and secondary peripheral chondrosarcomas being the most frequent. Their clinical symptoms are non-specific and include pain for several months, swelling and limited range of motion of the adjacent joints. Prompt diagnosis is important, as biological behaviour, imaging and histopathologic characteristics, treatment and prognosis differ considerably from their conventional intramedullary counterparts. Moreover, their imaging characteristics are not infrequently non-characteristic and may be misinterpreted as juxtacortical benign lesions leading to incorrect diagnosis and treatment, with life-threatening repercussions. Molecular studies and histopathological sampling are essential for accurate diagnosis. There are still numerous issues regarding the biology, pathophysiology and treatment options of these entities due to their rarity.

Abstract
Circular RNAs (circRNAs) are single-stranded RNAs generated from exons back-splicing from a single pre-mRNA, forming covalently closed loop structures which lack 5'-3'-polarity or polyadenylated tail. Ongoing research depicts that circRNAs play a pivotal role in tumorigenesis, tumor progression, metastatic potential and chemoresistance by regulating transcription, microRNA (miRNA) sponging, RNA-binding protein interactions, alternative splicing and to a lesser degree, protein coding. Sarcomas are rare malignant tumors stemming from mesenchymal cells. Due to their clinically insidious onset, they often present at advanced stage and their treatment may require aggressive chemotherapeutic or surgical options. This review is mainly focused on the regulatory functions of circRNAs on osteosarcoma progression and their potential role as biomarkers, an area which has prompted lately extensive research. The attributed oncogenic role of circRNAs on other mesenchymal tumors such as Kaposi Sarcoma (KS), Rhabdomyosarcoma (RMS) or Gastrointestinal Stromal Tumors (GISTs) is also described. The involvement of circRNAs on sarcoma oncogenesis and relevant emerging diagnostic, prognostic and therapeutic applications are expected to gain more research interest in the future.

Abstract
Myositis ossificans (MO) is a benign bone formation in an extra-skeletal location. The most common subtype of MO, the post-traumatic, usually develops in young males after a traumatic event or sports injury.MO may simulate malignant bone lesions such as extra-skeletal or surface osteosarcomas, or soft tissue sarcomas such as synovial sarcoma or undifferentiated pleomorphic sarcoma. In the early phase the diagnosis of MO is challenging because imaging and histopathological findings may be non-characteristic.Detailed medical history as well as clinical examination, follow-up imaging studies and histological assessment are crucial for a proper diagnosis. Early and accurate differential diagnosis between MO and malignant soft tissue and bone tumours is important to maximize. Cite this article: EFORT Open Rev 2021;6:572-583.

Abstract
OBJECTIVES In transplantation surgery, the ischaemic organ and reperfusion impairment after cold storage remains a considerable risk factor for impaired function and potential failure of the grafted organ. Substantial logistical efforts have been undertaken to reduce the cold ischaemic time because the demand for available transplant organs and the periods of cold ischaemia are increasing. METHODS Four molecules were investigated (erythropoietin, sildenafil, lazaroid [U74389G], octreotide) in individual intravenous infusions 1 hour before the organ was harvested. This study was performed in 30 healthy landrace/large-white pigs (male; >10 weeks old; average weight, 22 ± 2 kg) in groups of six. The organs were studied at harvest, and at 8 and 24 hours post-harvest. RESULTS The lazaroid molecule increased malondialdehyde (MDA) levels in the liver and pancreas at 8 hours. Hepatic lazaroid molecules improved liver histology at 8 and 24 hours. For kidneys, erythropoietin had a positive effect at 24 hours post-harvest. For the pancreas, octreotide showed better performance. In the lungs, there was less interstitial oedema with erythropoietin and lazaroid compared with the control group at 8 hours post-harvest. CONCLUSION All molecules had a positive effect and decreased ischaemia/reperfusion graft injury. Thus, pretreatment before organ harvest has a beneficial role.

Abstract
CASE We present a case of a 35-year-old-man with a giant sclerosing epithelioid fibrosarcoma (SEF) of the thigh. The patient presented with a history of a painful thigh mass. Plain radiographs revealed a soft-tissue mass with extensive calcifications, whereas on magnetic resonance imaging, a lobulated mass between the adductors and the posterior muscles of the thigh was noted. A wide en block resection was undertaken, and the histopathology confirmed the diagnosis of SEF. Postoperative radiation therapy was followed. The patient had no signs of recurrence at the 4-year follow-up. CONCLUSION The clinicopathological, imaging characteristics, and treatment options of this rare soft-tissue tumor are discussed.

Abstract
Background Polycythemia vera (PV) is characterized by red cell mass expansion in the peripheral blood and can be complicated with thrombosis, bleeding, evolution to acute myeloid leukemia (AML) or a fibrotic phase. Paroxysmal nocturnal hemoglobinuria (PNH) in an acquired clonal haematopoietic stem cell disorder associated with chronic intravascular hemolysis, venous thrombosis, defective hematopoiesis, frequent episodes of infection and, rarely, leukemic transformation. Herein, we report an interesting case of a patient with coexistence of PNH clones and a JAK2V617F positive PV, with unusual thromboses without hemolysis. Case presentation A 51-year-old woman presented with increased levels of hematocrit, multiple liver, spleen, and left kidney infarctions and ascites; further investigation revealed a JAK2V617F-positive polycythemia vera and the presence of a significant PNH population (more than 90% CD55– CD59– cells among both granulocytes and red blood cells). Interestingly, the patient has experienced severe thrombotic events without any signs or symptoms of hemolysis. Conclusions This case raises questions over uncharted aspects of the PNH etiopathogenesis and its potential association with myeloproliferative neoplasms (MPN) and highlights the difficulty of diagnosing and managing patients with more than one potentially thrombophilic conditions, especially with established and severe thromboses.

Abstract
Primary extranodal non-Hodgkin lymphomas that involve skeletal muscles (PSML) are infrequent with non- specific features or symptoms. Therefore, their diagnosis can be immensely convoluted since they mimic other soft tissue tumors and diseases (34). In this study, the case of a 61-year-old male patient, who presented with a history of a 6-week left thigh oedema and concomitant pain in our Emergency Department, is discussed. The patient was initially reviewed in another institution; the results of imaging studies (ultrasound scan) were consistent with deep vein thrombosis (DVT).Despite treatment, the patient's pain and swelling was exacerbating, which forced him to visit our hospital. Magnetic resonance imaging (MRI) revealed a diffused mass in his right thigh, while fine needle aspiration cytology (FNAC) yielded a diagnosis of B-cell lymphoid hyperplasia. The patient was then referred to a tertiary cancer treatment center for further management.

Abstract
Glioblastoma (GBM) is the most common primary brain tumor in adults, and the most lethal form of glioma, characterized by variable histopathology, aggressiveness and poor clinical outcome and prognosis. GBMs constitute a challenge for oncologists because of their molecular heterogeneity, extensive invasion, and tendency to relapse. Glioma cells demonstrate a variety of deregulated genomic pathways and extensive interplay with epigenetic alterations. Epigenetic modifications have emerged as essential players in GBM research, with biomarker potential for tumor classification and prognosis and for drug targeting. Histone posttranslational modifications (PTMs) are crucial regulators of chromatin architecture and gene expression, playing a pivotal role in malignant transformation, tumor development and progression. Alteration in the expression of genes coding for lysine and arginine methyltransferases (G9a, SUV39H1 and SETDB1) and acetyltransferases and deacetylases (KAT6A, SIRT2, SIRT7, HDAC4, 6, 9) contribute to GBM pathogenesis. In addition, proteins of the sumoylation pathway are upregulated in GBM cell lines, including E1 (SAE1), E2 (Ubc9) components, and a SUMO-specific protease (SENP1). Preclinical and clinical studies are currently in progress targeting epigenetic enzymes in gliomas, including a new generation of histone deacetylase (HDAC), protein arginine methyltransferase (PRMT) and bromodomain (BRD) inhibitors. Herein, we provide an update on recent advances in glioma epigenetic research, focusing on the role of histone modifications and the use of epigenetic therapy as a valid treatment option for glioblastoma.

Abstract
Cardiac tumors range from benign to high grade malignancies. The incidence of cardiac involvement either by primary, or secondary tumors during autopsy is reported to be extremely low. Extranodal NK/T-cell lymphoma (ENKTL), nasal type is an unusual type of lymphoma. The skin is the second most common site of involvement after the respiratory tract. We present a case of a 63-year-old male, who was recently diagnosed with ENKTL, nasal type, who received chemotherapy, and died without any evident cause. The corpse was referred for routine medicolegal examination. Macroscopical determination of the cause of death was not feasible and subsequent histopathological examination revealed heart infiltration by ENKTL that was found in vivo in cutaneous lesions. Similar infiltrations existed in the pancreatic tissue. To the best of our knowledge, myocardial infiltration of ENKTL, inducing severe myocardial lesions that eventually caused death, is rare, with limited cases reported in the literature.

Abstract
Soft tissue tumors can be categorized molecularly into two categories: tumors which are known to have recurrent molecular alterations and tumors which do not have consistent recurrent molecular alterations or translocations. These "nontranslocation" associated sarcomas are clinically more aggressive than their more stable counterparts. However, recent advances in RNA sequencing have discovered recurrent novel fusions within the latter group, namely TERT-TRIO fusions. Furthermore, a recent report discovered this fusion in a spindle cell liposarcoma. Our case describes a novel fusion of CTNND2, a neighbor gene of TRIO, and TERT in a spindle cell liposarcoma, and provides further evidence that spindle cell liposarcoma should be a distinct entity from dedifferentiated liposarcoma.

Abstract
Introduction A colorectal inflammatory myofibroblastic tumour (IMT) is a rare but benign entity masquerading as a malignant tumour. Although the lung is considered the most common site of occurrence, IMTs may arise in diverse extrapulmonary locations. We describe a case of a colonic IMT in a patient who presented in the emergency setting. Case History A 77-year-old man was admitted at our emergency department with acute abdominal pain. Physical examination revealed vague tenderness of the lower abdomen and non-palpable masses. Preoperative evaluation revealed a mass in the right lower quadrant of the abdomen, possibly originating from the terminal ileum, 1-2cm from the caecum. Owing to the clinical impression of a potentially malignant lesion, the patient underwent subtotal colectomy and omentectomy. The pathology report suggested the morphological and immunohistochemical features were more compatible with a colonic IMT. Conclusions A colorectal IMT is a rare clinical entity that can easily mimic a highly malignant tumour and cannot be distinguished clinically or radiologically. An accurate diagnosis is based on histological examination and surgical resection is therefore usually required.

Abstract
Expression of thioredoxin-1 (TXN) and CXCL9 is not restricted to THRLBCL macrophages, but may be observed in histiocytes and neoplastic (HRS) cells of EBV + mixed cellularity (MC) classical Hodgkin lymphoma (cHL) and nodular lymphocyte predominant HL. We aimed to validate and extend the above observations in 174 cHL patients evaluating the immunohistochemical expression of TXN, CXCL9 and IFN-γ. HRS-cell CXCL9 expression was higher in latent membrane protein-1 (LMP1)+, MC and Stage IV. TXN and CXCL9 expression by cHL histiocytes was more frequent in LMP1+, MC and older patients (only for CXCL9). TXN expression by HRS cells (≥80%) was independently associated with better failure-free survival. In conclusion, markers of TCHRLBCL histiocytes (TXN, CXCL9), as well as IFN-γ are also expressed by histiocyte subsets and neoplastic cells of cHL. The expression of some of them is more prominent in EBV + MC, but not restricted to this subtype. The prognostic implication of TXN needs further evaluation.

Abstract
BACKGROUND The therapeutic properties of cannabinoids are well-known since ancient years. Growing evidence exist on endocannabinoid system (ECS) modulation related with human tumorigenesis. OBJECTIVE Taking into account the substantial role of ECS on immune cell regulation, the present review is aimed to summarize the emerging evidence concerning cannabinoid receptor (CBR) expression and cannabinoid ligand effects on haematological malignancies. CONCLUSIONS Most of cannabinoid actions, mainly CB2R-mediated against haematopoietic malignant cells, seem promising, as inhibition of cell proliferation and apoptosis and paraptosis induction have been documented. Cannabinoid ligands appear to activate rudimentary pathways for cell survival, such as ERK, JNK, p38 MAPK, and to induce caspase synthesis, in vitro. Such data are strongly recommended to be confirmed by in vivo experiments with emphasis on cannabinoid ligands' bioavailability and phytocannabinoid psychotropic properties. The preliminary antitumoral ECS effects and their relative lack of important side effects render ECS a promising therapeutic target for the treatment of haematological malignancies.

Abstract
The potential role of AKT/mTOR signalling proteins and its association with the Raf-MEK-ERK pathway was investigated in hairy cell leukaemia (HCL). BRAFV600E expression and activated forms of AKT, mTOR, ERK1/2, p70S6k and 4E-BP1 were immunohistochemically assessed in 77 BM biopsies of HCL patients and correlated with clinicopathological and BM microvascular characteristics, as well as with c-Caspase-3 levels in hairy cells. Additionally, we tested rapamycin treatment response of BONNA-12 wild-type cells or transfected with BRAFV600E. Most HCL cases expressed p-p70S6K and p-4E-BP1 but not p-mTOR, being accompanied by p-ERK1/2 and p-AKT. AKT/mTOR activation was evident in BONNA-12 cells irrespective of the presence of BRAFV600E mutation and was implicated in cell proliferation enhancement. In multivariate analysis p-AKT/p-mTOR/p-4E-BP1 overexpression was an adverse prognostic factor for time to next treatment conferring earlier relapse. When p-AKT, p-mTOR and p-4E-BP1 were examined separately only p-4E-BP1 remained significant. Our findings indicate that in HCL, critical proteins up- and downstream of mTOR are activated. Moreover, the strong associations with Raf-MEK-ERK signalling imply a possible biologic interaction between these pathways. Most importantly, expression of p-4E-BP1 alone or combined with p-AKT and p-mTOR is of prognostic value in patients with HCL.
