Abstract
Introduction: Central nervous system lymphomas (CNSLs) require effective treatment strategies due to aggressive nature of disease. Despite therapeutic approaches having improved in the last decades, there is no standard treatment for these patients. As a CNSL targeted-therapy IDARAM protocol was developed, the outcomes were reported with a few studies. We observed the R-IDARAM protocol in our CNSL cases, and we discuss the effectiveness, tolerability, and toxicity with a review of the literature in this article. Subjects and Methods: We retrospectively analyzed response rates, progression-free survival, adverse events, and long-term side effects in patients who were treated by modified R-IDARAM as standard clinical care of CNSL in our hematology department. Results: Response was achieved in five of nine patients. Three patients (two primary CNSL and one secondary CNSL) are still being followed up without disease progression with a median duration of follow-up of 79 months (88, 79, and 17 months, respectively). Manageable hematological side effects including thrombocytopenia and neutropenia were experienced by all patients. Conclusion: R-IDARAM protocol may be an option with high early response rates and manageable toxicity. Hematological side effects are the main problem, and long-term neurological toxicity is not common. Eligible patients must continue with autologous stem cell transplantation due to poor long-term survival outcomes.

Abstract
A rare tumor, primary central nervous system lymphoma can affect immunocompetent and immunocompromised patients. While sensitive to radiotherapy or chemotherapy crossing the blood-brain barrier, it often recurs. Modern treatment consists of high-dose methotrexate-based induction chemotherapy, often followed by consolidation with either radiotherapy or further chemotherapy. Neurotoxicity is however a concern with radiotherapy, especially for patients older than 60 years. The benefit of the addition of rituximab to chemotherapy is unclear. Targeted therapies and immunotherapy have been effective in some patients and are tested on a larger scale. Survival has improved in the last decade, but remains poor in older patients.

Abstract
Primary central nervous system lymphoma (PCNSL) is a type of highly invasive non-Hodgkin lymphoma. With a growing number of organ transplantation and immunosuppressant therapy, the incidence of PCNSL has been growing rapidly in recent years, which is attributed to the increased incidence of HIV/AIDS, a prominent risk factor for developing PCNSL. The rising rate of PCNSL incidence is the highest among the intracranial tumors. In the past 20 years, dozens of clinical trials related to PCNSL have been registered, but adequate therapeutics are still challenging. Currently, the chemotherapy regimens based on high-dose methotrexate and whole-brain radiotherapy are the two main therapeutic options; however, the toxicity associated with those is the main problem that challenges medical researchers. Novel agents and therapeutic strategies have been developed in recent years. In the current review, we describe advances in the treatment of PCNSL and discuss novel therapeutic approaches currently in development, such as the use of rituximab, disruption of the blood-brain barrier, and state-of-the-art radiotherapy.

Abstract
Primary central nervous system lymphoma (PCNSL) is a rare form of non-Hodgkin lymphoma with poor long-term survival. This study assessed methotrexate (MTX) plus idarubicin (IDA) in treating patients of PCNSL comparing to MTX alone therapy. A total of 100 patients were retrospectively enrolled and subjected to MTX alone (n = 52) and MTX plus IDA (n = 48). The completed response (CR) rate in patients treated with MTX plus IDA was 62.50%, and overall response (OR) rate was 79.17%, which in MTX alone cohort were 42.31% and 63.46% respectively. Median progression-free survival (PFS) of patients treated with MTX plus IDA was significantly better than those treated with MTX alone (18.35 months vs.8.45months, P = 0.000). The MTX plus IDA regimen exhibited a significantly better control of PCNSL. Further studies would be needed to confirm these results.

Abstract
Background Primary central nervous system lymphoma (PCNSL) is a rare subtype of non-Hodgkin's lymphoma (NHL). The aim was to evaluate response rate, progression free survival (PFS), overall survival (OS), and toxicity in PCNSL after systemic R-IDARAM and intrathecal immunochemotherapy with deferred radiotherapy. Results The response rate was 94% with 17 (89%) complete responses and 1 (5%) partial responses. Follow-up time is from 5 to 63 months (median, 39 months). Median survival has not been reached. 3-year overall survival and progression-free survival rates were 84.2% (CI 72.6% to 99.8%) and 63.2% (CI 41.4% to 73.8%). Systemic toxicity was mainly hematologic. Neurocognitive and neuromotor deterioration as a result of treatment occurred in only one patient (5%). Patients and Methods From September 2010 to June 2015, 19 consecutive patients with PCNSL (median age, 54 years) were enrolled into a pilot phase II study evaluating immunochemotherapy without radiotherapy. The patients were accrued to a chemotherapy regimen that incorporated rituximab, idarubicin, dexamethasone, cytarabine (Ara-c) and methotrexate (MTX) combined with intrathecal rituximab, MTX, dexamethasone and Ara-c. Conclusions The results indicate that R-IDARAM regimen with intrathecal immunochemotherapy is generally well tolerated and produces a high complete response rate and survival rate.

Abstract
Diffuse large B-cell lymphoma with secondary involvement of the central nervous system (SCNS-DLBCL) is a rare condition carrying a poor prognosis. No optimal therapeutic regimen has been identified. We retrospectively analysed 23 patients with SCNS-DLBCL treated with R-IDARAM (rituximab 375 mg/m(2) IV day 1; methotrexate 12·5 mg by intrathecal injection day 1; idarubicin 10 mg/m(2) /day IV days 1 and 2; dexamethasone 100 mg/day IV infusion over 12 h days 1-3; cytosine arabinoside 1000 mg/m(2) /day IV over 1 h days 1 and 2; and methotrexate 2000 mg/m(2) IV over 2 h day 3. Ten out of 23 (44%) patients had CNS involvement at initial presentation ('new disease'), 10/23 (44%) had relapsed disease and 3/23 (13%) had primary refractory disease. 14/23 (61%) of patients responded - 6 (26%) complete response, 8 (35%) partial response. Grade 3-4 haematological toxicity was seen in all cycles, with no grade 3-4 or long-term neurological toxicity. Median follow-up for surviving patients was 49 months. At 2 years, estimated progression-free survival (PFS) was 39% and overall survival (OS) was 52%. Encouraging outcomes were reported in patients with new disease, with 5-year estimated PFS of 50% and OS 75%. R-IDARAM is a well-tolerated regimen with encouraging efficacy in patients with SCNS-DLBCL, although patients with relapsed or refractory disease continue to fare poorly.

Abstract
Treatment of primary central nervous system lymphoma (PCNSL) in elderly patients remains unsatisfactory. To develop a new high-dose methotrexate (HD-MTX)-based regimen including idarubicin, a phase 1 multicenter dose escalation study was conducted to determine the maximum-tolerated dose (MTD) of idarubicin. Thirty-five immunocompetent patients with PCNSL were enrolled. The median age was 65 years (range, 60-70 years). MTX and vindesine (VDS) were given at the fixed dose of 3 g/m(2) (6-hr intravenous [IV]) and 3 mg/m(2) IV on day 1, respectively. Prednisolone (PRED) was given at the fixed dose of 60 mg/m(2) (IV or orally) on days 1-5. Idarubicin was escalated in increments of 2 mg/m(2) with doses ranging from 12-18 mg/m(2) IV on day 1. Treatment was repeated three times every 3 weeks. Dose-limiting toxicity (DLT) was defined as grade 4 neutropenia for more than 7 days, thrombocytopenia grade 4 or nonhaematological toxicity more than grade 2. The MTD of idarubicin was reached at 16 mg/m(2) . At this level, the main haematological toxicities were thrombocytopenia grade 4: 5% and neutropenia grade 3 or 4 (52%); the main nonhaematological toxicities were grade 3 or 4 infectious disease (5%) and grade 2 renal failure (9%). For the study population, median overall and progression-free survival were 19 and 13 months, respectively. Our study suggests that the MTD of idarubicin in combination with HD-MTX, VDS, and PRED, should be 16 mg/m(2) . Further studies will be necessary to challenge a standard treatment in elderly patients with PCNSL.

Abstract
The overall response rates and long-term survival of primary central nervous system lymphoma (PCNSL) are still significantly inferior to the results achieved in similar subtypes of extranodal non-Hodgkin's lymphoma. It is clearly necessary to investigate new therapeutic methods on PCNSL. We encountered three patients histologically documented PCNSL as diffuse large B-cell lymphoma (DLBCL). They were treated with R-IDARAM which comprised rituximab, idarubicin, dexamethasone, cytarabine and methotrexate. Patient 1 received stereotactic brachytherapy (SBT) prior to chemotherapy performed with iodine-125 seeds (cumulative therapeutic dose 50 Gy). After six cycles of R-IDARAM at 3-weekly intervals, radiotherapy was applied at a dosage of 2000–4000 cGy in conventional schedule (180 or 200 cGy/day) to whole brain or spinal cord in all patients. Complete remission (CR) was achieved after first two cycles of R-IDARAM in all patients. All three patients remained in CR at the time of this report with a median duration of follow-up of 23 months (ranging from 13 to 41 months). Three patients have been alive for 41, 13, 16 months respectively until now. The patient with the longest survival time was the one given SBT prior to chemotherapy. This study suggests that R-IDARAM combining with radiotherapy maybe a high effective regimen in PCNSL patients especially those with primary central nervous system DLBCL. A comprehensive treatment combining internal radiotherapy by SBT, modified R-IDARAM and followed reduced external radiotherapy may be a new treatment concept for PCNSL with higher efficiency and lower toxicity.

Abstract
Reported rates of central nervous system (CNS) involvement in mantle cell lymphoma (MCL) are highly variable but substantial (4-26%). Data is lacking regarding risk factors for CNS relapse, and for those patients in whom CNS prophylaxis could be beneficial. We present single institution retrospective analysis of data of baseline features, clinical course, rate of CNS disease and putative risk factors in 62 patients with MCL (18 female, 44 male). CNS disease (all cases were symptomatic) occurred in four patients at a median of 12 months (range 1-58) from diagnosis, with a crude incidence of 6.5% and 5-year actuarial incidence of 5 +/- 3%. Two cases had blastic MCL at diagnosis. Survival after CNS relapse ranged from 2-9 months. Patients who developed CNS disease had a significantly shorter survival from diagnosis than those who did not (P = 0.0024). Symptomatic CNS disease in patients with MCL either at presentation or relapse is an uncommon but devastating complication. In younger patients, more aggressive immuno-chemotherapy regimens containing CNS-penetrating agents may reduce the incidence of CNS disease. While not routinely justified for all patients, CNS prophylaxis may particularly benefit patients with blastic histology at diagnosis, or those with systemic relapse after first-line treatment.

Abstract
The use of radiotherapy (RT) with chemotherapy has improved disease free survival and control in primary central nervous system lymphoma (PCNSL). We have encountered three patients with histologically documented central nervous system lymphoma. In all patients pathological diagnosis was B-cell lymphoma. We modified IDARAM regimen to R-IDARAM to enhance and optimize chemotherapeutic components for the treatment of PCNSL. We made three changes: (i) we added rituximab 375 mg/m(2) day 1; (ii) increased dose of MTX from 2 to 3 g/m(2); and (iii) administered two additional courses of R-IDARAM after cranial RT. Following complete staging after course 2, radiotherapy was applied at a dosage of 3600-4140 cGy in conventional schedule (180 or 200 cGy per day) to whole brain (with 3600 cGy to eyes in one case because of eye involvement) and then 2 additional courses of R-IDARAM (totally four courses) chemotherapy regimen were applied. Complete remission (CR) was achieved after first two cycles of R-IDARAM in patient 1 and 3 and after four cycles in patient 2. Currently, three patients have been alive for 29, 10, 15 months respectively. Currently there is no standard treatment modality for PCNSL. Increased dosage of MTX, adding rituximab and consolidation of the IDARAM to R-IDARAM regimen may improve disease control and outcome in PCNSL patients.

Abstract
PURPOSE To bring together multidisciplinary experts to discuss primary central nervous system lymphoma (PCNSL) and primary intraocular lymphoma (PIOL). METHODS NIH campus workshop discussion focusing on future work in both clinical and basic lymphoma research. RESULTS The discussion lead to recommendations on elucidating disease pathobiology, improving diagnostic accuracy and sensitivity, and novel therapeutic strategies. CONCLUSIONS Approaches which have been successfully applied to other neoplasms, such as microarray, may be applied to improve diagnostic accuracy and sensitivity of PCNSL and PIOL and should be systematically incorporated into clinical trials of both. Development of animal models of PCNSL and PIOL may be useful in understanding the unique ocular and CNS milieu. Disease detection by radiological, nuclear medicine, molecular and flow cytometric approaches should be systematically studied to improve early diagnosis, accurate staging, and response evaluation. Improved therapy remains the ultimate goal. Efforts in these arenas should be coordinated on a national and international level.

Abstract
PURPOSE OF REVIEW Primary central nervous system lymphoma is a rare form of extranodal non-Hodgkin's lymphoma that is confined to the central nervous system and eye. Numerous studies examining this disorder have been published in the past 2 years. This review will discuss recent advances in the understanding of the pathology, radiographic appearance, and treatment of this disorder. RECENT FINDINGS Novel treatment regimens continue to be studied for newly diagnosed and recurrent primary central nervous system lymphoma. As overall survival improves, the burden of late neurotoxicity has become more apparent. Neuropsychological testing of patients treated with chemoradiation shows significant cognitive deficits that can be attributed to whole brain irradiation. Standardization of phase II clinical trials across individual institutions remains an important goal within the oncology community. The International Primary Central Nervous System Lymphoma Collaborative Group (IPCG) has proposed guidelines for the baseline evaluation and response criteria for clinical trials of the disorder. In addition, series of patients with uncommon histological variants of primary central nervous system lymphoma have been published. SUMMARY In 2005, the optimal treatment for primary central nervous system lymphoma remains undefined. Treatment of newly diagnosed disease should include methotrexate-based chemotherapy but the role of irradiation and intrathecal chemotherapy remain unclear. Salvage therapy for progressive or recurrent primary central nervous system lymphoma is an area of active interest but no standard recommendations exist at the present time. Future studies on the biology of recurrent primary central nervous system lymphoma should help to clarify treatment options for these patients.

Abstract
All adult patients with Burkitt lymphoma or lymphoblastic lymphoma should receive central nervous system (CNS)-directed therapy with both intrathecal and high-dose systemic chemotherapy. There is no evidence to support the routine use of prophylactic CNS-directed therapy in any specific subgroup of adult patients with 'low grade' lymphomas. There are some anatomical sites where involvement by lymphoma is associated with a higher risk of CNS relapse. These probably include testis, breast, paranasal sinuses and the epidural space. Multivariate analyses strongly support a raised serum lactate dehydrogenase level and the involvement of more than one extranodal site as the strongest predictors of subsequent CNS relapse. A high International Prognostic Index score may replace the use of the above two factors in combination. There is evidence of good efficacy when intrathecal chemotherapy and high-dose systemic chemotherapy are used in combination. It is not clear how the best balance between the 'sensitivity' and 'specificity' of the choice of patients to receive CNS-directed therapy can be achieved.

Abstract
CHOP (cyclophosphamide, doxorubicin, vincristine and prednisolone) has been the standard chemotherapy regimen used for diffuse large cell lymphomas for over 30 years. Idarubicin is a 4-demethoxy-anthracycline analogue of daunorubicin that has proven activity in non-Hodgkin lymphoma, and has been reported to cause less cardiotoxicity. We therefore initiated a randomised trial of standard dose CHOP versus CIOP (cyclophosphamide, idarubicin, vincristine and prednisolone), in which doxorubicin 50 mg/m2 was substituted by idarubicin 10 mg/m2, a dose thought to have equivalent anti-lymphoma activity. This trial was closed prematurely after 211 patients had completed therapy when a lower complete remission (CR) rate was noted in the CIOP arm. The formal results with long-term follow up are now reported. Overall response rate was 84% in the CHOP arm and 78% in the CIOP arm, CR rates were 70% and 52% respectively in all patients (P=0.013) and 73% and 52% respectively for the eligible patients (P=0.0084). At a median of 8 years follow-up, 4-year progression-free survival for all patients was 56% in the CHOP arm and 40% in the CIOP arm (P=0.0096). Overall survival for all patients was 65% in the CHOP arm and 56% in the CIOP arm (P=0.14). Results for eligible patients were comparable. CIOP containing idarubicin at a dose of 10 mg/m2 is clearly inferior to standard CHOP.
