[Show abstract][Hide abstract] ABSTRACT: Importance
The clinical features of diffuse large B-cell lymphoma (DLBCL) subtype of ocular adnexal lymphoma have not previously been evaluated in a large cohort to our knowledge.Objective
To investigate the clinical features of ocular adnexal DLBCL (OA-DLBCL).Design, Setting, and Participants
This retrospective international cooperative study involved 6 eye cancer centers. During 30 years, 106 patients with OA-DLBCL were identified, and 6 were excluded from the study. The median follow-up period was 52 months.Main Outcomes and Measures
Overall survival, disease-specific survival (DSS), and progression-free survival were the primary end points.Results
One hundred patients with OA-DLBCL were included in the study (median age, 70 years), of whom 54 (54.0%) were female. The following 3 groups of patients with lymphoma could be identified: primary OA-DLBCL (57.0%), OA-DLBCL and concurrent systemic lymphoma (29.0%), and ocular adnexal lymphoma relapse of previous systemic lymphoma (14.0%). Of 57 patients with primary OA-DLBCL, 53 (93.0%) had Ann Arbor stage IE disease, and 4 (7.0%) had Ann Arbor stage IIE disease. According to the TNM staging system, 43 of 57 (75.4%) had T2 tumors. Among all patients, the most frequent treatments were external beam radiation therapy with or without surgery (31.0%) and rituximab–cyclophosphamide, hydroxydaunorubicin, vincristine sulfate, prednisone (CHOP) or rituximab–CHOP-like chemotherapy with or without external beam radiation therapy (21.0%). The 5-year overall survival among the entire cohort was 36.0% (median, 3.5 years; 95% CI, 2.5-4.5 years). Relapse occurred in 43.9% (25 of 57) of patients with primary OA-DLBCL. Increasing T category of the TNM staging system was predictive of DSS (P = .04) in primary OA-DLBCL, whereas the Ann Arbor staging system was not. However, when taking all 100 patients into account, Ann Arbor stage was able to predict DSS (P = .01). Women had a longer median DSS than men (9.8 years; 95% CI, 1.9-17.7 years vs 3.3 years; 95% CI, 1.6-5.0; P = .03).Conclusions and Relevance
Most patients with primary OA-DLBCL were seen with Ann Arbor stage IE and TNM T2 disease. The 5-year overall survival was between 2.5 and 4.5 years, which is the 95% CI around the median of 3.5 years in this cohort. Increasing T category appears to be associated with decreased DSS among patients with primary OA-DLBCL. When taking all patients into account, sex and Ann Arbor stage also seem to be DSS predictors.

[Show abstract][Hide abstract] ABSTRACT: OncomiRs miR-21 and miR-155 have been linked to lymphomagenesis, but information on their implication in diffuse large B-cell lymphoma (DLBCL) is limited. Here, we used locked nucleic acid-based in situ hybridization (ISH) detection techniques on formalin-fixed paraffin-embedded DLBCL tissue samples to identify miR-155 and miR-21 at the cellular level in 56 patients diagnosed with DLBCL, and compared them to miR array data. miR-155 was observed in tumor cells in 19/56 (33.9%) of the samples evaluated by ISH. miR-21 was localized to the stromal compartment in 41/56 (73.2%). A subset of these, 16/56 (28.6%), also showed labeling in tumor cells. When comparing ISH-scores and miR array data, miR-155 in tumor cells, identified by ISH, was associated with miR-155 expression in miR array data (P=0.030). Equally, miR-21 expression by miR array data were highly associated with miR-21 ISH-scores in the stromal cells (P=0.002), whereas no association between miR array data and ISH of miR-21 in tumor cells was observed (P=0.673). We found no association of miR-155 and miR-21 with overall survival or germinal center B-cell-like (GCB) versus non-GCB-like subtypes of DLBCL. In conclusion, miR-ISH added to the biological interpretation of miR expression in DLBCL compared with miR array data, but miR-155 and miR-21 ISH did not add prognostic information in this series.This is an open-access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivitives 3.0 License, where it is permissible to download and share the work provided it is properly cited.

[Show abstract][Hide abstract] ABSTRACT: PurposeTo characterize the clinicopathological features of follicular lymphoma of the ocular adnexal region.Methods
Retrospective nation-based study of Danish patients with ocular adnexal follicular lymphoma from January 1st 1980 through December 31st 2009.ResultsTwenty-four patients with ocular adnexal follicular lymphoma were identified. Fourteen (58%) of the patients were females. The median age was 63 years (range: 42–96 years). Eleven (46%) of the patients had primary ocular adnexal lymphoma, seven (29%) had an ocular adnexal lesion in conjunction with a concurrent systemic lymphoma and six patients (25%) presented with an ocular adnexal relapse. The most frequently affected sites were the lacrimal gland (38%) and the orbit (33%). Thirteen patients (54%) presented with Ann Arbor stage IE lymphoma, four (17%) had stage IIE, two patients (8%) stage IIIE, and five patients (21%) had stage IV lymphoma. Radiotherapy was primarily used in patients with primary lymphoma and those with a stage IE/IIE relapse (82%), while stage IIIE/IV lymphomas most frequently received alkylating chemotherapy (67%). Complete remission was observed in 19 of the patients (79%), but of these 11(58%) had a relapse. The 10-year overall survival for the entire cohort was 59%. The translocation t(14;18) was detected in 16 patients (16/24, 76%). Recurrence was only observed in patients with the t(14;18) (p = 0.05, log-rank).Conclusions
Ocular adnexal follicular lymphoma is more commonly found in elderly female patients. The lacrimal gland is relatively frequently involved. Radiotherapy is the treatment of choice for localized ocular adnexal follicular lymphoma providing a favourable prognosis for majority of patients.

[Show abstract][Hide abstract] ABSTRACT: Pancytopenia can be caused by lack of bone marrow function and can have different origins. A 66-year-old woman was admitted with severe sepsis, and the blood results revealed pancytopenia. A bone marrow biopsy was performed, and the primary diagnosis was hypocellular acute myeloid leukaemia with 20% blasts, but a diagnosis of myelodysplastic syndrome (MDS) was considered. After 30 days without any chemotherapeutic treatment her peripheral blood was normalised. In the meanwhile she was diagnosed with a small cell lung cancer. In this case the MDS-like condition was caused by a paraneoplastic phenomenon to the undiagnosed lung tumour.

[Show abstract][Hide abstract] ABSTRACT: IMPORTANCE The clinical features of the follicular subtype of ocular adnexal lymphoma (OAL) have not been previously evaluated in a large cohort. OBJECTIVE To characterize the clinical features of follicular OAL. DESIGN, SETTING, AND PARTICIPANTS We performed a retrospective multicenter study that involved 6 eye cancer centers from January 1, 1980, through December 31, 2010. A total of 105 patients with follicular OAL were identified, of which 7 patients were excluded because of missing clinical data. The median follow-up time was 52 months (range, 13-118 months). MAIN OUTCOMES AND MEASURES Overall survival, disease-specific, and progression-free survivals were the primary end points. RESULTS Ninety-eight eligible patients with follicular OAL were included; 60 (61%) were women. The median patient age was 63 years (range, 32-96 years). Sixty-nine patients (70%) had primary OAL, 19 (19%) had OAL in conjunction with a concurrent systemic lymphoma, and 10 (10%) presented with an ocular adnexal relapse. The lacrimal gland (28%), conjunctiva (28%), and orbit (28%) were the most frequently involved sites. Of the 69 patients with primary follicular lymphoma, 38 (55%) presented with Ann Arbor stage IE lymphoma, and 31 (45%) had stage IIE lymphoma. Patients with disseminated lymphoma had stage IIIE (9 of 19 [47%]) and stage IV (10 of 19 [53%]) disease, whereas patients with a relapse of systemic lymphoma presented with stage IE (8 of 10 [80%]), stage IIE (1 of 10 [10%]), and stage IIIE (1 of 10 [10%]) disease. Patients with primary follicular lymphoma (n = 69) and those with isolated ocular relapse (n = 9) were treated with external beam radiation therapy (EBRT) (35 of 78 [45%]) or EBRT plus chemotherapy (22 of 78 [28%]). Patients presenting with stage IIIE-IV follicular lymphoma (n = 20) most frequently received chemotherapy (9 of 20 [45%]) or EBRT plus chemotherapy (4 of 20 [20%]). The 10-year overall survival for the entire study cohort was 60%. Primary patients treated with EBRT had a better disease-specific survival compared with patients receiving ERBT plus chemotherapy (10-year disease-specific survival, 94% vs 40%; P = .02 by log-rank test). CONCLUSIONS AND RELEVANCE Follicular OAL was more commonly found in elderly female patients. These tumors were equally noted to involve the conjunctiva, lacrimal gland, and orbit. Patients with ocular adnexal follicular lymphoma primarily treated with EBRT had a more favorable long-term disease-specific survival.
[Show abstract][Hide abstract] ABSTRACT: Purpose: To characterize the clinicopathological features of diffuse large B-cell lymphoma (DLBCL) of the ocular adnexal region.
Methods: The present series of orbital and adnexal DLBCLs were found by searching the Danish Registry of Pathology between 1980 and 2009. Histological specimens were re-evaluated using a panel of monoclonal antibodies. Clinical files from all patients with confirmed DLBCL were collected.
Results: A total of 34 patients with DLBCL of the ocular adnexal region were identified. Eighteen of the patients were men. The patients had a median age of 78 years (range 35–97 years). Ninety-seven per cent of the patients had unilateral ocular adnexal region involvement, and the orbit (76%) was the most frequently affected site. Nineteen patients (56%) presented with Stage I lymphoma. Of these, 18 were diagnosed with primary lymphoma. Four patients (12%) had Stage II, one patient (3%) had Stage III and ten patients (29%) presented with Stage IV lymphoma. The 5-year overall survival (OS) rate for the whole study group was 20%. The patients with Stage I lymphoma had a significantly better 5-year OS rate (28%) than patients in Stage II-IV (5-year OS rate, 9%). In Cox regression analysis, concordant bone marrow involvement and the International Prognostic Index (IPI) score were prognostic factors for OS.
Conclusions: Diffuse large B-cell lymphoma of the ocular adnexal region is mainly prevalent in elderly patients. Most patients had unilateral orbital involvement. The overall prognosis is poor. Concordant bone marrow involvement and the IPI score were independent prognostic factors for mortality.

[Show abstract][Hide abstract] ABSTRACT: To characterize the clinicopathologic features of lacrimal gland lymphoma.
All cases of lacrimal gland lymphoma from January 1, 1975, through December 31, 2009, were retrieved from The Danish Registry of Pathology. Histologic specimens were reevaluated using a panel of monoclonal antibodies. Clinical files from all patients with confirmed lymphoma were collected.
Twenty-seven patients with lacrimal gland lymphoma were identified. Eight of the patients were men and 19 were women; the median (range) age was 69 (43-87) years. The distribution of lymphoma subtypes was as follows: extranodal marginal zone lymphoma, 10 (37%); follicular lymphoma, 5 (19%); diffuse large B-cell lymphoma, 4 (15%); mantle cell lymphoma, 3 (11%); chronic lymphocytic leukemia/small lymphatic lymphoma, 2 (7%); and unclassified B-cell lymphoma, 3 (11%). Twenty-two patients (81%) had stage I or II lymphoma, 1 patient (4%) had stage III lymphoma, and 4 patients (15%) had stage IV lymphoma. Patients with stage I or II lymphoma were treated with radiotherapy (15 [67%]), chemotherapy (3 [14%]), chemotherapy plus radiotherapy (1 [5%]), and surgery (3 [14%]). Patients presenting with stage III or IV lymphoma were treated with chemotherapy alone. Complete remission was observed in 23 of the patients (85%), although 12 (44%) of these had a relapse, independent of subtype, stage, or treatment. The 5-year overall survival was 70%.
Malignant lymphoma of the lacrimal gland is relatively rare and is mostly prevalent in elderly women. The distribution of lacrimal gland lymphoma subtypes resembles that of lymphoma subtypes of the salivary glands. The majority of lacrimal gland lymphomas are low grade, and the prognosis is relatively good.

[Show abstract][Hide abstract] ABSTRACT: To characterise clinicopathological features of mantle cell lymphoma (MCL) in the orbital and adnexal region.
Data on lymphoid lesions were retrieved searching the Danish Ocular Lymphoma Database 1980-2005. Specimens were collected from Danish pathological departments and re-evaluated with a panel of monoclonal antibodies. For all patients with confirmed MCL the complete clinical files were collected and reviewed.
Twenty-one patients with MCL in the orbital and adnexal region were identified comprising 9% (21/230) of all lymphoma in the ocular region. There were 18 male patients and three female patients with an age range from 60 to 90 years (median 75 years). Orbital and adnexal region MCL as first presenting symptom comprised 67% of the patients. Of these, 71% had bilateral involvement. The orbit (71%) and eyelids (64%) were the most commonly affected sites. All but two presented in stage III/IV. Secondary MCL comprised 33% of the patients. Bilateral affection (29%) was less common in this patient group. The median survival was not different between the two presentation groups. Patients receiving anti-CD20 (rituximab)-containing chemotherapy had a significantly better 5-year overall survival (OS) rate (83%) than patients in treatment regimes without rituximab (5-year OS rate, 8%).
Orbital and adnexal region MCL presents in elderly males. The orbit and eyelid are frequently involved. There is a very high proportion of systemic involvement in general with MCL of the orbital and adnexal region. Most patients presented with stage IV disease and had multiple relapses and short survival time. Treatment with rituximab-containing chemotherapy improved survival significantly compared with combination chemotherapy without rituximab.

[Show abstract][Hide abstract] ABSTRACT: With a lifetime risk of 1% and 700 new cases per year, Non-Hodgkin lymphoma (NHL) is the seventh most frequent type of cancer in Denmark. The incidence of NHL has increased considerably in Western countries over the last decades; consequently, NHL is an increasing clinical problem.
Ophthalmic lymphoma, (lymphoma localized in the ocular region, i.e. eyelid, conjunctiva, lacrimal sac, lacrimal gland, orbit, or intraocularly) is relatively uncommon, accounting for 5%–10% of all extranodal lymphomas. It is, however, the most common orbital malignancy.
The purpose of this thesis was to review specimens from all Danish patients with a diagnosis of ophthalmic lymphoma during the period 1980–2005, in order to determine the distribution of lymphoma subtypes, and the incidence- and time trends in incidence for ophthalmic lymphoma. Furthermore, an extended analysis of the most frequent subtype, extranodal marginal zone lymphoma (MALT lymphoma), was done to analyse clinical factors and cytogenetic changes with influence on prognosis.
A total of 228 Danish patients with a biopsy-reviewed verified diagnosis of ocular adnexal-, orbital-, or intraocular lymphoma were identified. We found that more than 50% of orbital- and ocular adnexal lymphomas were of the MALT lymphoma subtype, whereas diffuse large B-cell lymphoma (DLBCL) predominated intraocularly (Sjo et al. 2008a). Furthermore, lymphoma arising in the lacrimal sac was surprisingly predominantly DLBCL (Sjo et al. 2006). Incidence rates were highly dependent on patient age. There was an increase in incidence rates for the whole population from 1980 to 2005, corresponding to an annual average increase of 3.4% (Sjo et al. 2008a).
MALT lymphoma arising in the ocular region was found in 116 patients (Sjo et al. 2008b). One third of patients had a relapse or progression of disease after initial therapy and relapses were frequently found at extra-ocular sites. Overall survival, however, was not significantly poorer for patients with relapse.
Furthermore, we found that the frequency of translocations involving the MALT1- and IGH-gene loci is low in ocular region MALT lymphoma (2 of 42, 5%), but may predict increased risk of relapse (Sjo et al. 2008b).
In conclusion the incidence of ophthalmic lymphoma is increasing at a high rate in Denmark. Ophthalmic lymphoma consists primarily of MALT lymphoma. The molecular pathogenesis of MALT lymphoma arising in the ocular region rarely involves translocations in the MALT1- and IGH-gene loci.

[Show abstract][Hide abstract] ABSTRACT: To evaluate clinical, immunophenotypical, and cytogenetical characteristics of 116 patients with a diagnosis of extranodal marginal zone lymphoma (EMZL) presenting primarily in the ocular region.
Specimens from all patients with a diagnosis of ophthalmic lymphoma in Denmark during the period 1980 to 2005 were reviewed and reclassified according to the World Health Organization (WHO) classification. Cases reclassified as EMZL were selected and reviewed with respect to clinical characteristics and outcome. The presence of translocations involving IGH and/or MALT1 was investigated in 42 specimens by fluorescence in situ hybridization (FISH).
Median age was 69 years. Most lymphomas were located in the orbit. Approximately one fourth of the patients had disseminated disease at presentation. One third experienced a relapse or progression of disease after initial therapy, and relapses were frequently found at extraocular sites. Five-year progression-free survival and overall survival (OS) rates were 71% and 75%, respectively. Translocations involving the IGH- or MALT1-gene loci were detected in 2 (5%) of 42 specimens. In Cox regression multivariate analysis, IGH-translocation was the only factor associated with PFS, whereas a favorable International Prognostic Index (IPI) score was the most reliable predictor of OS.
EMZL presenting in the ocular region usually runs an indolent course, but relapses are frequently seen. The IPI-score was the most reliable independent parameter for estimating risk of death in our cohort of patients. Furthermore, we found that the frequency of translocations involving the MALT1- and IGH-gene loci is low in ocular region EMZL.
[Show abstract][Hide abstract] ABSTRACT: To evaluate patient characteristics and incidence of ophthalmic lymphoma in Denmark during the period 1980 to 2005.
All patients in Denmark with a diagnosis of ophthalmic lymphoma during the period 1980 to 2005 were retrieved from three different population-based registries. Specimens from all patients were collected and reclassified according to the World Health Organization (WHO) classification system. Incidence rates were calculated by using Poisson regression models.
A total of 228 patients with a histologically verified diagnosis of ophthalmic lymphoma were included. There was an equal distribution of males and females. The most frequent lymphoma subtype was extranodal marginal zone B-cell lymphoma (MALT [mucosa-associated lymphoid tissue] lymphoma, 55.5%) and most cases were located in the orbit (56.8%). High-grade lymphoma subtypes were found more frequently in males than in females. Incidence rates were highly dependent on the patient's age. For all ages, a statistically significant annual average increase of 3.4% during the 26-year period was found. This increase was primarily due to a rise in the incidence of MALT lymphoma.
In the Danish population ophthalmic lymphoma consists primarily of orbital MALT lymphoma. Although it is a rare disease in mostly elderly patients, the incidence of ophthalmic lymphoma is increasing at a rapid pace.

[Show abstract][Hide abstract] ABSTRACT: Diffuse large B-cell lymphoma (DLBCL) is a frequent lymphoma subtype with a heterogeneous behavior and a variable response to conventional chemotherapy. This clinical diversity is believed to reflect differences in the molecular pathways leading to lymphomagenesis. In this study, we have analyzed pretreatment, diagnostic samples from 108 DLBCL by immunohistology for expression of four markers linked to germinal center B-cells (CD10, Bcl-6), postgerminal center B-cells (MUM1) and apoptosis (Bcl-2). The results indicate that both CD10 and Bcl-6 are favorable prognostic indicators, in contrast to Bcl-2, which is an adverse parameter. Furthermore, using two algorithms for distinction between low- and high-risk patients proposed by Hans et al. (Blood, 2004; 103:275) and Muris et al. (Journal of Pathology, 2006; 208:714), it is shown that both are useful for predicting outcome in DLBCL. However, in this report, the algorithm of Hans et al. was superior to that of Muris et al. These findings confirm and extend other studies and indicate that different prognostic subgroups of DLBCL can be distinguished by simple immunohistological investigations for a limited number of markers. Whether these groups are also relevant for individual treatment decisions will be important to investigate in prospective studies.

[Show abstract][Hide abstract] ABSTRACT: To define the clinical and histopathological characteristics of primary lacrimal sac lymphoma in a predominantly white population.
Specimens of lacrimal sac lymphoma and follow up data were solicited from members of the Ophthalmic Oncology Task Force of the European Organization for Research and Treatment of Cancer (EORTC) and the European Ophthalmic Pathology Society (EOPS). Specimens were stained with haematoxylin and eosin and an immunohistochemical panel against leucocyte antigens was applied. Diagnosis was reached by consensus of five experienced pathologists according to the World Health Organization classification system. The histopathological findings were correlated with the clinical data.
Of 15 primary lacrimal sac lymphomas, five (33%) were diffuse large B cell lymphoma (DLBCL), five (33%) were extranodal marginal zone B cell lymphoma of mucosa associated lymphoid tissue (MALT lymphoma), three were classified as "transitional MALT lymphoma," being in transition from MALT lymphoma to DLBCL, and two were unclassified B cell lymphomas. Nine of the patients were female, and the median age at the time of diagnosis was 71 years (range 45-95 years). The most frequent presenting symptoms were epiphora (85%), swelling in the region of the lacrimal sac (79%), and dacryocystitis (21%). All but one patient presented in stage I. Systemic spread occurred in three of nine patients (33%). The 5 year overall survival was 65%.
DLBCL and MALT lymphoma are equally common in the lacrimal sac in contrast with the remaining periorbital and/or orbital region where MALT lymphoma predominates.

[Show abstract][Hide abstract] ABSTRACT: To present two cases of rapidly growing tumors in the ocular adnexa. Both tumors were Epstein-Barr virus (EBV) positive peripheral T-cell lymphoma.
Case 1 was a 60-year-old man with a non-tender ulcerating tumor involving the lateral third of both upper and lower right eyelid. Case 2 was a 55-year-old man with a swelling of the left eyelid expanding cranially and dislocating the left eye, resulting in proptosis and diplopia. Both patients underwent incisional biopsy that did not disclose the malignant nature of the tumors. Clinical evaluation resulted in suspicion of malignancy and surgical excision was performed.
The tumors were found to be consistent with EBV-positive peripheral T-cell lymphoma.
Peripheral T-cell lymphoma is uncommon but a diagnosis to be considered in a patient with a tumorous lesion in the eye region. Furthermore, peripheral T-cell lymphoma may be EBV-positive.
