Abstract
Indolent T-lymphoblastic proliferation (iT-LBP) is a rare, non-clonal, extrathymic lymphoid proliferation with an immature T cell phenotype, indolent clinical course, and excellent prognosis. Although their pathogenesis is unclear, they are reported to be associated with Castleman disease, follicular dendritic cell tumors/sarcomas, angioimmunoblastic T cell lymphoma, hepatocellular carcinoma (HCC), myasthenia gravis, and acinic cell carcinoma. There are around 51 reported cases of iT-LBP in the literature. Recognition and accurate diagnosis of this entity is critical as it shares morphologic and immunophenotypic features with an aggressive malignancy-acute T cell leukemia/lymphoma (T-ALL). IT-LBP in HCC post-liver transplant and in metastatic sites has not been reported in the literature. Two case reports of patients presenting with recurrent and metastatic HCC in post-liver transplant settings are described. A 50-year-old man with an end-stage liver disease with HCC underwent liver transplant. A year later, he developed pulmonary metastasis with associated iT-LBP. A 69-year-old man underwent liver transplant for end-stage liver disease and HCC. Eighteen months later, he developed recurrent HCC in the transplanted liver and omental metastasis; both sites showed HCC with iT-LBP. iT-LBP in both patients expressed TdT, CD3, and CD4 and lacked CD34 and clonal T cell receptor gene rearrangements. On retrospective review, the pre-transplant HCC specimens lacked iT-LBP. We present two cases of iT-LBP associated with HCC in novel settings-in post-liver transplant patients and in recurrent/metastatic sites of HCC. In addition, a comprehensive literature review of clinical, histological, and immunophenotypic characteristics of reported cases of iT-LBP is presented.

Abstract
Diffuse midline glioma (DMG), H3 K27-altered, are aggressive central nervous system tumors which are universally fatal, with a median survival of 8-12 months after diagnosis. Here, we present a patient who was incidentally found to have a lesion, concerning for tumor, within the right thalamus on brain magnetic resonance imaging at 2 years of age. Twelve years later, subsequent imaging showed that the lesion had enlarged, with biopsy consistent with DMG harboring an H3 K27M mutation. This case illustrates an unusual presentation of a DMG, H3 K27-altered, with an indolent course. Such findings highlight the fact that more research is needed to understand what factors may contribute to these tumors' malignant course.

Abstract
T-prolymphocytic leukemia (T-PLL) is a rare, aggressive T-cell leukemia, and patients typically present with marked peripheral blood lymphocytosis. Approximately 15-20 % of patients may present with moderate and relative stable lymphocytosis and an indolent clinical course that can persist for a few years. However, eventually these patients go on to develop marked lymphocytosis and rapidly progressive disease. We report a 72-year-old man who presented with multicompartmental lymphadenopathy and a normal complete blood count. Excision of left and right cervical lymph nodes showed replacement of the lymph node architecture by a small T-cell neoplasm positive for CD3, CD4, CD5, CD7 and TCL-1, and negative for CD8, CD20, CD30 and ALK. Subsequent bone marrow evaluation showed minimal bone marrow involvement by a T-cell neoplasm associated with TCL1A rearrangement in 11 % of cells supporting the diagnosis of T-PLL. Despite treatment, he showed progressive lymphadenopathy while remarkably maintaining normal white blood cell counts until he eventually developed leukocytosis of 110.9 × 103/uL 26 months later. Review of the literature identified only a single abstract reporting a patient with a similar lymphoma-like presentation and normal white blood cell count; however, that case showed significant bone marrow involvement in stark contrast to the current case. In summary, we report a highly unusual case of T-PLL can initially presenting with an aleukemic or lymphoma-like clinical picture, which can make establishing the diagnosis challenging.

Abstract
Nasal mucormycosis is a rare opportunistic infection of the nasal cavity and paranasal sinuses caused by saprophytic fungi which can rapidly lead to death. It usually affects individuals with poorly controlled diabetes mellitus (especially those with ketoacidosis), solid malignancies, iron overload, extensive burns, in patients undergoing treatment with glucocorticosteroid agents and in patients with neutropenia related to haematologic malignancies. Presentation of nasal mucormycosis is always very extensive, but in some patients, it can present in chronic indolent form also. Here, we present a case of 65-year old male with a history of exposed nasal bone after nasal trauma 8 months back. His diabetes was in control with oral hypoglycaemics. Debridement and local flap closure was done. Culture showed the growth of Lichtheimia corymbifera and in HPE, the fungus was seen branching at right angles. So, we conclude that the possibility of nasal mucormycosis should always be borne in mind so that early and effective treatment can be initiated on time to decrease the morbidity and mortality.

Abstract
OPINION STATEMENT When selecting therapy for patients with indolent non-Hodgkin lymphoma (iNHL) including follicular (FL), marginal zone (MZL), small lymphocytic (SLL), and lymphoplasmacytic lymphoma (LPL)/Waldenström macroglobulinemia (WM), there are several factors to consider. With a median age around 70 at diagnosis, many patients have accumulated comorbid conditions that may limit treatment options. Although incurable for most, iNHL is a chronic disease with a median overall survival measured in years to decades. This long natural history changes the risk-to-benefit balance with a lower acceptance of toxicity early in the treatment course compared to that of aggressive lymphomas. Despite a recent rapid increase in available therapies, overall progress in iNHL has been slow for several reasons. Initial trials grouped iNHLs together making it challenging to appreciate the differential activity among subtypes. We have not been able to develop prognostic models that maintain validity in the era of chemotherapy-free options. Predictive markers have been elusive and without identified molecular signatures, it is challenging to select and sequence therapy. With these clinical factors in mind, in addition to the heterogeneity among and within iNHLs, I do not have a standard treatment algorithm and feel each patient should have an individualized treatment approach. This review focuses on recent updates and controversies in the management of iNHL with a focus on FL and MZL.

Abstract
BACKGROUND Evidence has accumulated showing that an increase in thyroid cancer incidence reflects overdiagnosis of clinically unimportant lesions due to the rise in the use of neck ultrasonography. In the manuscript we examine the hypothesis that the rise in thyroid cancer incidence in Russia is largely caused by overdiagnosis. MATERIALS AND METHODS Incidence and mortality rates of thyroid cancer for Russia overall and its administrative regions were abstracted from the statistical database of the Ministry of Health of Russia. For incidence trends, we calculated the percentage change, linear regression coefficient and p-value. The calculation of excess cases was based on expected age-specific distributions assuming that the incidence of thyroid cancer increases exponentially with age, as predicted by the multistage model of carcinogenesis. FINDINGS Over the study period (1989-2015) the age standardized incidence of thyroid cancer has tripled in Russian women and doubled in men. Strong support for the hypothesis that the increase in thyroid cancer incidence may be artificial is evident from age-specific incidence trends: increases in incidence in middle age but not in older ages, thereby altering the age curves from the expected exponential shape to an "inverted U" shape. The number of observed cases of thyroid cancer exceeded the expected number by 138, 325 or 70 % of all cases diagnosed with thyroid cancer. We attribute the excess cases to detection by ultrasonography clinically unimportant lesions. This is supported by a very high incidence -to-mortality ratio, low case fatality, high and growing prevalence of thyroid cancer. CONCLUSION Although there is an evidence that exposure to iodine 131 (131I) is an important cause of the increase in incidence of thyroid cancer in high-risk populations, we have shown that this increase could largely be attributed to overdiagnosis associated with ultrasonography screening. Overdiagnosis is the only explanation of the increase in thyroid cancer incidence in low-risk regions.

Abstract
Bendamustine is a preferred first-line chemoimmunotherapy regimen for indolent non-Hodgkin's lymphoma (iNHL). Emerging evidence suggests an increased incidence of late-onset complications with bendamustine-based regimens compared with CHOP/CVP; however, this evidence is limited. We retrospectively compared late-onset complications from January 2005 to May 2020 in adults with previously untreated iNHL who received rituximab or obinutuzumab with CHOP, CVP, or bendamustine. Forty-six patients received CHOP/CVP; 119 received bendamustine. No difference in incidence of late-onset infections was observed. Bendamustine led to a higher rate of prolonged and unresolved lymphocytopenia and a greater incidence of late-onset neutropenia. Many patients receiving bendamustine did not have lymphocyte recovery even three years following administration. Ongoing infection prophylaxis with bendamustine-based regimens may offset translation of these laboratory findings to late-onset infectious risk.

Abstract
Mantle cell lymphoma (MCL) is considered one of the most aggressive lymphoid tumors. However, it sometimes displays indolent behavior in patients and might not necessitate treatment at diagnosis; this has been described as "smoldering MCL" (SMCL). There are significant differences in the diagnosis, prognosis, molecular mechanisms and treatments of indolent MCL and classical MCL. In this review, we discuss the progress in understanding the molecular mechanism of indolent MCL to provide insights into the genomic nature of this entity. Reported findings of molecular features of indolent MCL include a low Ki-67 index, CD200 positivity, a low frequency of mutations in TP53, a lack of SOX11, normal arrangement and expression of MYC, IGHV mutations, differences from classical MCL by L-MCL16 assays and MCL35 assays, an unmutated P16 status, few defects in ATM, no NOTCH1/2 mutation, Amp 11q gene mutation, no chr9 deletion, microRNA upregulation/downregulation, and low expression of several genes that have been valued in recent years (SPEN, SMARCA4, RANBP2, KMT2C, NSD2, CARD11, FBXW7, BIRC3, KMT2D, CELSR3, TRAF2, MAP3K14, HNRNPH1, Del 9p and/or Del 9q, SP140 and PCDH10). Based on the above molecular characteristics, we may distinguish indolent MCL from classical MCL. If so, indolent MCL will not be overtreated, whereas the treatment of classical MCL will not be delayed.

Abstract
Leukemic, non-nodal mantle cell lymphoma (MCL) is a distinct, rare, indolent variant of mantle cell lymphoma, but can relapse aggressively. It can present with lymphocytosis with chronic lymphocytic leukemia (CLL)-like morphologic and immunophenotypic features as was initially considered in the index case. However, at time of splenectomy, two years later cyclin D1 overexpression was shown and the disease was realized to be leukemic non-nodal MCL. The patient was followed for 21 years, without therapy, before he developed clinically aggressive MCL with lymphadenopathy. Lymph node biopsy showed MCL, pleomorphic variant. We review the literature and discuss the features of leukemic non-nodal MCL as well as the potential pitfalls in diagnosis. Furthermore, we are not aware of another cases reported with a 21 year interval from initial diagnosis of leukemic non-nodal MCL to aggressive MCL.

Abstract
Background Indolent T-cell lymphoproliferative disorder of the gastrointestinal tract is a rare low-grade clonal lymphoid proliferation, included as a provisional entity in the current World Health Organization classification. The disease is generally localized to the gastrointestinal tract, mainly small bowel and colon. Involvement of other organs is infrequently reported. The majority of patients show a protracted clinical course with persistent disease. A prolonged survival, even without treatment, is common. Case presentation A 28-year-old woman had a 2-year history of dyspepsia and lactose intolerance. Autoimmune diseases and celiac disease were excluded. No gross lesions were identified by endoscopy. Multiple gastric biopsies showed a small-sized lymphoid infiltrate, expanding the lamina propria, with a non-destructive appearance. The lymphoid cells were positive for CD3, CD4, CD5, CD7 and negative for CD20, CD8, CD56, CD103, PD1, CD30, ALK1, CD10, BCL6, perforin, TIA-1, Granzyme B and Epstein-Barr virus-encoded RNA. KI-67 index was low (5%). Molecular analysis revealed a clonal T-cell receptor γ rearrangement. Bone marrow was microscopically free of disease, but molecular testing identified the same T-cell receptor γ rearrangement present in the gastric biopsies. After the diagnosis of indolent T-cell lymphoproliferative disorder of the gastrointestinal tract, the patient received steroid therapy, only for 2 months. She is alive, with a stable disease restricted to the stomach, at 12 months from diagnosis. Conclusions Indolent T-cell lymphoproliferative disorder is usually a disease of adulthood (median age: 51 yrs). The small bowel and colon are the sites most commonly involved. Our case occurred in a young woman and affected the stomach, sparing small intestine and colon. Clonality testing identified involvement of bone marrow, a site infrequently affected in this disease. Our aim is focusing on the main diagnostic issues. If appropriate immunostainings and molecular analysis are not performed, the subtle infiltrate may be easily overlooked. The risk of misdiagnosis as more aggressive lymphomas, causing patient overtreatment, needs also to be considered.

Abstract
Despite the rise in the incidence of papillary thyroid carcinoma (PTC) during the last 30 years, the mortality rate due to PTC has remained static. One reason for this phenomenon is the indolent nature of some of the tumors that are diagnosed as PTC. A subgroup of tumors, which often exhibited such indolent behavior, was encapsulated/well-circumscribed follicular lesions that showed PTC nuclear features. Despite their indolent behavior, these tumors were managed as was any other PTC, often with total thyroidectomy and radioactive iodine (RAI) treatment. In order to prevent overtreatment of these tumors, they were recently reclassified as "non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP)." Since it is proposed that NIFTP be managed in a more conservative manner, its diagnosis is now based on strict histological criteria. The genetic basis of these diagnostic criteria and the utility of molecular markers in the diagnosis of NIFTP are currently being scrutinized. The aim of this review is to discuss the events that led to the emergence of the term NIFTP, as well as its histological and molecular background.

Abstract
Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) with favorable pathological and clinical features may be considered as indolent lesions, and therefore be amenable to conservative management. According to the primary tumor site, different non-aggressive approaches, based on endoscopic resection or simple active surveillance, can be proposed to selected patients fulfilling specific criteria. Tumor size, Ki67 proliferative index and depth of invasion are markers that can be used in order to identify these subjects. Patients with type I gastric NENs <1 cm as well as those with non-ampullary duodenal NENs <1 cm with no associated syndrome can be safely managed by endoscopic resection. On the other hand, an active surveillance approach is preferred over surgery for patients with asymptomatic, non-functioning pancreatic NENs ≤2 cm without dilation of the main pancreatic duct or bile duct. As far as NENs of the appendix are concerned, appendectomy should be considered as curative when a R0 resection has been achieved in the presence of a tumor ≤1.5 cm, graded as G1 and without lymphovascular invasion. Finally, G1 rectal NENs ≤1 cm without invasion of the muscular layer can be safely treated by endoscopic resection. Therefore, surgeons should be aware of the existence of indolent GEP-NENs, in order to avoid unnecessary operations with associated postoperative complications.

Abstract
Mantle cell lymphoma (MCL) is a biologically heterogeneous disease, and patients may experience a clinical course ranging from indolent to very aggressive. Observational studies suggest that a subset of patients can be safely observed for a period of months to years from initial diagnosis without adversely impacting their outcomes. However, identification of candidates for the "watch and wait" approach remains challenging because selection criteria are not well-defined. Studies that prospectively stratify patients on the basis of MCL biology and disease risk will be informative, and patients with indolent MCL may be ideal candidates for frontline clinical trials exploring novel therapies.

Abstract
INTRODUCTION Mantle cell lymphoma (MCL) is an aggressive B-cell neoplasm, but clinically indolent subtypes are also recognized. Data on the utility of mutation profiling in the context of routine workup and its role in risk-stratification of MCL patients are limited. In this study, we describe the mutational landscape and clinicopathologic correlates of a series of MCL cases at a single-institution setting. METHODS Samples from 26 patients with MCL were evaluated by NGS using DNA extracted from peripheral blood (PB) or bone marrow (BM). Evaluation of extent of PB or BM involvement was performed using flow cytometry immunophenotyping. RESULTS The study group included 17 (65%) men and 9 (35%) women with a median age of 65 years (range, 50-94). Twenty-one (81%) patients had nodal MCL (N-MCL) and 5 (19%) had the "leukemic variant" (L-MCL). Mutated genesincluded TP53 (35%), ATM (27%), CARD11 (10%); and FBXW7, NOTCH1, SPEN, BIRC3 (~5% each). Most mutations were clonal in nature. Ten unique TP53 mutations were identified in 9 samples, including 3 L-MCL cases. There was no difference in the frequency of TP53 mutations between L-MCL and N-MCL groups (p = 0.3), but TP53 mutations were subclonal in 2/3 L-MCL cases. Identification of clonal TP53 alterations in L-MCL patients prompted initiation of therapy despite low tumor burden. CONCLUSIONS TP53 is commonly mutated in MCL. TP53 mutations may be clonal or subclonal. Seemingly indolent L-MCL may harbor subclonal TP53 mutations which may serve as a useful biomarker for prognostication, therapeutic planning, follow-up monitoring, and early detection of clonal expansion.

Abstract
Background Extranodal NK/T-cell lymphoma, nasal type (ENKTCL-NT), is a rare aggressive subtype of non-Hodgkin lymphoma characterized by angioinvasion, angiodestruction, necrosis and strong association with Epstein-Barr virus (EBV). ENKTCL-NT occurs worldwide and is more prevalent in Asian and the Native American populations of Mexico, Central and South America. It represents approximately 10% of all peripheral T-cell lymphomas worldwide. The aim of this report is to present a rare case of ENKTCL-NT with an unusually indolent clinical course and low-grade histopathologic features. Case presentation A 71-year-old Asian woman with a long-standing history of seasonal rhinosinusitis presented with persistent nasal congestion, cough, and fever unresponsive to antihistamines and antibiotics. Histopathological evaluation of a polypoid nasal mass revealed an atypical infiltrate with predominantly small lymphoid cells that were CD2+, surface CD3-, cytoplasmic CD3+, CD5(dim)+, CD7(dim)+, cytotoxic markers (granzyme B and perforin)+, EBER+ and CD56-. The Ki-67 proliferative index was very low (< 1%). T-cell receptor gamma gene rearrangement studies were positive for a monoclonal rearrangement, and sequencing studies identified a novel KIT mutation (p. K167 M, c. 500 A > T). A diagnosis of low-grade ENKTCL-NT was rendered. Conclusions Our case of ENKTCL-NT is unusual due to (1) an indolent clinical course (2) low-grade histopathologic features including a low proliferative index (3) lack of CD56 expression and (4) a novel KIT mutation. This case raises awareness of the existence of a subset of cases of ENKTCL-NT that can potentially be misdiagnosed as a reactive process, particularly in patients with recurrent chronic rhinosinusitis.

Abstract
PURPOSE OF REVIEW The purpose of the study is to summarize the current conundrums in the management of marginal zone lymphomas (MZL). RECENT FINDINGS In 2017, the US Food and Drug Administration (FDA) approved ibrutinib, a first in class Bruton Tyrosine Kinase inhibitor, for the treatment of relapsed/refractory MZL based on pivotal open-label phase II trial demonstrating an overall response rates of 48%. Clinical trials design utilizing chemotherapy-free regimens for relapsed/refractory disease are gaining popularity. Recent studies have identified multiple genetic biomarkers that helped characterize and prognosticate different subtypes of MZL. MZLs are heterogeneous, mostly indolent, malignancies derived from B lymphocytes. Three disease subtypes are recognized, extranodal, nodal, and splenic. The disease characteristics, clinical picture, and treatment algorithms vary considerably based on subtype and site of involvement. Recent discoveries have enhanced our knowledge of the pathogenesis of MZLs leading to development of more accurate prognostic models as well as novel targeted systemic therapies.

Abstract
The survival of multiple myeloma patients has improved significantly over the last several decades. However, the median overall survival of these patients remains less than 5 years. In this report, we discuss 4 cases of multiple myeloma patients that showed long survival. Interestingly, these patients had severe organ damage at diagnosis, used only conventional agents, and did not always show deep response. Although current guidelines recommend novel agents to achieve deep response, the current cases suggest that some multiple myeloma patients may not need intensive treatment. Here, we discuss 4 cases of symptomatic but indolent transplant-ineligible myeloma.

Abstract
Thyroid cancer incidence is rapidly increasing due to increased detection and diagnosis of indolent thyroid cancer, i.e. cancer that is likely to be clinically insignificant. Clinical, radiologic, and pathologic features predicting indolent behavior of thyroid cancer are still largely unknown and unstudied. Existing clinicopathologic staging systems are useful for providing prognosis in the context of treated thyroid cancer but are not designed for and are inadequate for predicting indolent behavior. Ultrasound studies have primarily focused on discrimination between malignant and benign nodules; some studies show promising data on using sonographic features for predicting indolence but are still in their early stages. Similarly, molecular studies are being developed to better characterize thyroid cancer and improve the yield of fine needle aspiration biopsy, but definite markers of indolent thyroid cancer have yet to be identified. Nonetheless, active surveillance has been introduced as an alternative to surgery in the case of indolent thyroid microcarcinoma, and protocols for safe surveillance are in development. As increased detection of thyroid cancer is all but inevitable, increased research on predicting indolent behavior is needed to avoid an epidemic of overtreatment.

Abstract
Leukemic non-nodal mantle cell lymphoma (lMCL) is a particular subtype of mantle cell lymphoma (MCL), characterized by leukemic non-nodal disease and slow progression. Recognition of this entity is relevant to avoid overtreatment. Despite indolent clinical behaviour, lMCL might transform to a more aggressive disease. The purpose of this study was to compare lMCL with classical MCL (cMCL) and aggressive MCL (aMCL) using immunohistochemistry, interphase fluorescence in situ hybridization (FISH), and array-based comparative genomic hybridization, in order to identify biomarkers for lMCL diagnosis and prognosis. Seven lMCL patients were included. All had bone marrow involvement without lymphadenopathy. An lMCL phenotype was distinct from that of cMCL and aMCL: SOX11-, ATM+, PARP1+/-, and low KI67 (average 2 %). Beyond the t(11;14) translocation, fewer secondary cytogenetic alterations were found in lMCL compared to cMCL and aMCL, including deletion of PARP1 and 13q14. At last follow-up, one patient with lMCL had died of disease and another had progressive disease. These patients were respectively 13q14 deletion- and PARP1-positive. One other case of lMCL harbored a 13q14 deletion associated with PARP1 deletion. This patient had indolent disease. lMCL has a particular phenotype and fewer secondary cytogenetic alterations than cMCL and aMCL. PARP1 protein expression and 13q14 deletion are associated with a progressive clinical course of lMCL and should be included in initial diagnostic studies as predictors of unfavorable outcome. PARP1 deletion is involved in lMCL pathogenesis and might confer advantage.

Abstract
BACKGROUND Next-generation sequencing is revealing genomic heterogeneity in localized prostate cancer (CaP). Incomplete sampling of CaP multiclonality has limited the implications for molecular subtyping, stratification, and systemic treatment. OBJECTIVE To determine the impact of genomic and transcriptomic diversity within and among intraprostatic CaP foci on CaP molecular taxonomy, predictors of progression, and actionable therapeutic targets. DESIGN, SETTING, AND PARTICIPANTS Four consecutive patients with clinically localized National Comprehensive Cancer Network intermediate- or high-risk CaP who did not receive neoadjuvant therapy underwent radical prostatectomy at Roswell Park Cancer Institute in June-July 2014. Presurgical information on CaP content and a customized tissue procurement procedure were used to isolate nonmicroscopic and noncontiguous CaP foci in radical prostatectomy specimens. Three cores were obtained from the index lesion and one core from smaller lesions. RNA and DNA were extracted simultaneously from 26 cores with ≥90% CaP content and analyzed using whole-exome sequencing, single-nucleotide polymorphism arrays, and RNA sequencing. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Somatic mutations, copy number alternations, gene expression, gene fusions, and phylogeny were defined. The impact of genomic alterations on CaP molecular classification, gene sets measured in Oncotype DX, Prolaris, and Decipher assays, and androgen receptor activity among CaP cores was determined. RESULTS AND LIMITATIONS There was considerable variability in genomic alterations among CaP cores, and between RNA- and DNA-based platforms. Heterogeneity was found in molecular grouping of individual CaP foci and the activity of gene sets underlying the assays for risk stratification and androgen receptor activity, and was validated in independent genomic data sets. Determination of the implications for clinical decision-making requires follow-up studies. CONCLUSIONS Genomic make-up varies widely among CaP foci, so care should be taken when making treatment decisions based on a single biopsy or index lesions. PATIENT SUMMARY We examined the molecular composition of individual cancers in a patient's prostate. We found a lot of genetic diversity among these cancers, and concluded that information from a single cancer biopsy is not sufficient to guide treatment decisions.

Abstract
Single Ig IL-1-related receptor (SIGIRR) is a negative regulator of toll-like receptor 4 and IL-1-mediated activation of nuclear factor κ-light-chain enhancer of activated B cells. The purpose of this study was to qualitatively and quantitatively determine SIGIRR protein expression in human prostate tissues and associate SIGIRR expression with clinical parameters. SIGIRR expression was quantified in glandular prostate tissue using immunohistochemistry and multispectral imaging, and expression was evaluated in relation to clinicopathological features of benign prostatic hyperplasia and prostate cancer (PCa). Subgroupings of low Gleason score (≤ 6 and 3 + 4) and high Gleason score (4 + 3 and ≥ 8) were used for patient outcomes. SIGIRR was predominantly expressed in the cytoplasm and nucleus of the prostatic epithelium with little expression within the stroma. Compared with normal prostate, cytoplasmic SIGIRR expression was similar in benign prostatic hyperplasia, high-grade prostatic intraepithelial neoplasia, PCa, and metastases. A decrease in nuclear expression was found in metastasis samples (P = .04). Changes in SIGIRR expression were not associated with Gleason score, pathological stage, tumor volume, surgical margin status, or serum prostate-specific antigen (P > .05). Nuclear (P = .96) and cytoplasmic (P = .89) SIGIRR expressions were not related to patient outcomes in univariable analysis, but in the analysis of patients with low Gleason scores, high cytoplasmic SIGIRR expression was associated with biochemical recurrence in both univariable (P = .01) and multivariable (hazard ratio, 2.31 [95% confidence interval 1.05-5.06]; P = .04) analyses. Similarly, in multivariable analysis of only low-stage (pT2) tumors, SIGIRR independently predicted biochemical recurrence (P = .009). We conclude that SIGIRR predicts biochemical recurrence in patients with low Gleason score and low pathological stage PCa.

Abstract
BACKGROUND Although screening programmes of smokers have detected resectable early lung cancers more frequently than expected, their efficacy in reducing mortality remains debatable. To elucidate the biological features of computed tomography (CT) screening detected lung cancer, we examined the mRNA signatures on tumours according to the year of detection, stage and survival. METHODS Gene expression profiles were analysed on 28 patients (INT-IEO training cohort) and 24 patients of Multicentre Italian Lung Detection (MILD validation cohort). The gene signatures generated from the training set were validated on the MILD set and a public deposited DNA microarray data set (GSE11969). Expression of selected genes and proteins was validated by real-time RT-PCR and immunohistochemistry. Enriched core pathway and pathway networks were explored by GeneSpring GX10. FINDINGS A 239-gene signature was identified according to the year of tumour detection in the training INT-IEO set and correlated with the patients' outcomes. These signatures divided the MILD patients into two distinct survival groups independently of tumour stage, size, histopathological type and screening year. The signatures can also predict survival in the clinically detected cancers (GSE11969). Pathway analyses revealed tumours detected in later years enrichment of the PI3K/PTEN/AKT pathway, with up-regulation of PDPK1, ITGB1 and down-regulation of FOXO1A. Analysis of normal lung tissue from INT-IEO cohort produced signatures distinguishing patients with early from late detected tumours. INTERPRETATION The distinct pattern of "indolent" and "aggressive" tumour exists in CT-screening detected lung cancer according to the gene expression profiles. The early development of an aggressive phenotype may account for the lack of mortality reduction by screening observed in some cohorts.

Abstract
The central nervous system (CNS) is an important area of involvement for both high-grade, aggressive primary and secondary lymphomas. Although follicular lymphoma represents a low-grade histology, it may rarely present with CNS involvement. Here, we describe a patient diagnosed with follicular lymphoma who was presented with cerebellar involvement.

Abstract
Background Extranodal natural killer (NK)/T-cell lymphoma is a subtype of lymphoma that is derived from NK cells. It is considered as an aggressive form of non-Hodgkin's lymphoma because of frequent relapses and resistance to treatment. Relapsed NK/T-cell lymphoma often follows a fulminant course that is refractory to conventional chemotherapy treatment. Methods Several patients with extranodal NK/T-cell lymphoma showed long-term survival in spite of frequent relapses. Thus, the medical records of patients diagnosed with extranodal NK/T-cell lymphoma from 1995 to 2007 were reviewed and assessed. Results Of the 140 cases reviewed, 6 were selected (4.29%). Each of these patients had a minimum of 3 relapses or disease progression during the follow-up period, and their median overall survival was 66 months (range, 42-89 months). They were grouped according to the atypical clinical behavior observed: (1) repeated relapses or progression (≥3 times) during follow-up; and (2) long-term survival of more than 40 months, as the longest overall survival median was previously considered at approximately 40 months. The clinicopathological and laboratory characteristics of these patients were similar to those of other extranodal NK/T-cell lymphoma patients. However, 5 of the studied cases involved relatively lower expression of the proliferation-related antigen Ki-67 (<40-50%), indicating less proliferative activity. Clinically, they showed delayed relapse for at least 20 months after the initial complete remission. Conclusion Our observations suggest that the clinical behavior of some extranodal NK/T-cell lymphoma patients differs from the typical clinical course.
