Abstract
Primary central nervous system lymphoma (PCNSL), a rare variant of non-Hodgkin's lymphoma, is characterized by distinct biological characteristics and clinical behaviors, and patient prognosis is not satisfactory. The advent of high-dose (HD) methotrexate (HD-MTX) therapy has significantly improved PCNSL prognosis. Currently, HD-MTX-based chemotherapy regimens are recognized as first-line treatment. PCNSL is sensitive to radiotherapy, and whole-brain radiotherapy (WBRT) can consolidate response to chemotherapy; however, WBRT-associated delayed neurotoxicity leads to neurocognitive impairment, especially in elderly patients. Other effective approaches include rituximab, temozolomide, and autologous stem-cell transplantation (ASCT). In addition, new drugs against PCNSL such as those targeting the B-cell receptor signaling pathway, are undergoing clinical trials. However, optimal therapeutic approaches in PCNSL remain undefined. This review provides an overview of advances in surgical approaches, induction chemotherapy, radiotherapy, ASCT, salvage treatments, and novel therapeutic approaches in immunocompetent patients with PCNSL in the past 5 years. Additionally, therapeutic progress in elderly patients and in those with relapsed/refractory PCNSL is also summarized based on the outcomes of recent clinical studies.

JOURNAL OF RADIATION RESEARCH 2016; 57:164-168. [PMID: 26661856 PMCID: PMC4795951 DOI: 10.1093/jrr/rrv085] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/30/2015] [Revised: 10/15/2015] [Accepted: 10/22/2015] [Indexed: 06/05/2023]
Abstract
Whole-brain radiotherapy (WBRT) has been an important component of treatment for primary central nervous system lymphoma (PCNSL), but delayed neurotoxicity has been a matter of concern. We have employed partial-brain radiotherapy (PBRT) with wide margins for PCNSL patients with a single lesion or a few lesions. In this study, we evaluated the treatment outcome in PCNSL patients undergoing PBRT. Between 2003 and 2014, 24 patients were treated with PBRT; 16 received high-dose-methotrexate (MTX) -containing chemotherapy before PBRT. Conventional fractionation with a median dose of 54 Gy was used. For reference, 15 patients undergoing MTX-based chemotherapy and WBRT were also analyzed. The 3-year overall survival rate was 60% for all 24 patients undergoing PBRT and 68% for the 16 patients undergoing MTX-based chemotherapy plus PBRT. The 3-year progression-free survival rate was 41% for all 24 patients undergoing PBRT and 36% for the 16 patients undergoing MTX-based chemotherapy. The in-field recurrence rate was 26% and the out-of-field recurrence rate was 15% at 3 years for all 24 patients undergoing PBRT. The rates for in-field recurrence and the out-of-field recurrence were 27% and 21%, respectively, for the 16 patients undergoing MTX-based chemotherapy. CNS-recurrence rates were similar in patients undergoing MTX-based chemotherapy and PBRT to the rates in those undergoing MTX-based chemotherapy and WBRT. Neurocognitive dysfunction developed in 3 of the 16 patients undergoing MTX + PBRT and in 4 of 15 patients undergoing MTX + WBRT (P = 0.68). PBRT seems to be a feasible treatment option for solitary PCNSL. Further investigations are warranted to evaluate the advantages of PBRT over WBRT.

Analysis of radiotherapy in 1054 patients with primary central nervous system lymphoma treated from 1985 to 2009. Clin Oncol (R Coll Radiol) 2014; 26:653-60. [PMID: 25034088 DOI: 10.1016/j.clon.2014.06.011] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2014] [Revised: 05/12/2014] [Accepted: 05/29/2014] [Indexed: 11/25/2022]
Abstract
AIMS Data on primary central nervous system lymphoma that had been collected through surveys for four consecutive periods between 1985 and 2009 were analysed to evaluate outcomes according to treatment. MATERIALS AND METHODS All had histologically proven disease and had received radiotherapy. No patients had AIDS. Among 1054 patients, 696 died and 358 were alive or lost to follow-up. The median follow-up period for surviving patients was 37 months. RESULTS For all patients, the median survival time was 24 months; the 5 year survival rate was 25.8%. Patients treated with methotrexate-based chemotherapy and radiation had a higher 5 year survival rate (43%) than those treated with radiation alone (14%) and those treated with non-methotrexate chemotherapy plus radiation (20%), but differences in relapse-free survival were smaller among the three groups. The 5 year survival rate was 25% for patients treated with whole-brain irradiation and 29% for patients treated with partial-brain irradiation (P = 0.80). Patients receiving a total dose of 40-49.9 Gy had a higher 5 year survival rate (32%) than those receiving other doses (21-25%, P = 0.0004) and patients receiving a whole-brain dose of 30-39.9 Gy had a higher 5 year survival rate (32%) than those receiving ≥40 Gy (13-22%, P < 0.0005). Patients receiving methotrexate-based chemotherapy and partial-brain radiotherapy (≥30 Gy) had a 5 year survival rate of 49%. CONCLUSIONS The optimal total and whole-brain doses may be in the range of 40-49.9 and <40 Gy, respectively, especially in combination with chemotherapy. Patients receiving partial-brain irradiation had a prognosis similar to that of those receiving whole-brain irradiation. With methotrexate-based chemotherapy, partial-brain radiotherapy may be worth considering for non-elderly patients with a single tumour.

Abstract
BACKGROUND The aim of our study was to analyze changes over time in the characteristics, treatment, and outcome of patients with primary central nervous system lymphoma (PCNSL). METHODS Data on 315 patients with histologically proven PCNSL undergoing radiotherapy between 2005 and 2009 were collected from 20 Japanese institutions using a questionnaire. These data were then compared with data on 273 patients treated during the period 1995-2004 and those on 466 patients treated during the period 1985-1994. RESULTS In terms of patient and tumor characteristics, we found a significant increase in mean patient age in the 2005-2009 period compared to the 1985-2004 period (63 vs. 58-59 years, respectively) and in the percentage of patients with better performance status (PS) during the 2005-2009 period compared with the 1995-2004 period (World Health Organization PS 0-2: 73 vs. 65 %, respectively). Regarding treatment, relative to the 1995-2004 period, significant changes in the 2005-2009 period were (1) decreased rate of attempting tumor resection (23 vs. 44 %); (2) increased use of chemotherapy (78 vs. 68 %), and (3) increased use of methotrexate (MTX)-containing regimens (84 vs. 53 %). The 5-year overall survival rates were 15.3, 30.1, and 36.5 % for patients seen during the 1985-1994, 1995-2004, and 2005-2009 periods, respectively, but relapse-free survival did not improve between the 1995-2004 and 2005-2009 periods (26.7 vs. 25.7 % at 5 years, respectively). Patients receiving MTX-containing chemotherapy had 5-year survival rates of 19, 50, and 44 % during these three periods, respectively. CONCLUSIONS Although patient backgrounds differed among the study periods, recent trends were a high patient age, better PS, avoidance of extensive tumor resection, more frequent use of chemotherapy, and improved survival. The recent improvement in survival may be due to improvements in second-line treatment and supportive care.

Abstract
Up until the late 1970s, radiation therapy played an important role in the treatment of primary central nervous system lymphoma (PCNSL) but more recently its role has changed due to the increased use of systemic chemotherapy. In this article, the current status of radiotherapy for PCNSL and optimal forms of radiotherapy, including the treatment volume and radiation dose, are discussed. Data from nationwide Japanese surveys of PCNSL patients treated with radiation therapy suggest that the prognosis of PCNSL patients improved during the 1990s, in part due to the use of high-dose methotrexate-containing chemotherapy. The prognosis of patients treated with radiation alone also improved. Radiotherapy still seems to play an important role in the attempt to cure this disease.

Abstract
The best therapeutic management in primary CNS lymphomas remains to be defined due to the small size and short follow-up of retrospective series, methodological pitfalls and limited number of prospective studies, and the paucity of randomized trials. This review focuses on the current therapeutic approaches, most commonly used drugs, role of intrathecal chemotherapy and indications for consolidation radiotherapy, providing recommendations for ordinary clinical practice. Some important therapeutic issues, such as the management of meningeal and intraocular lymphomas, as well as the relevance of salvage therapy as a playground for evaluation of new drugs, are also analyzed. Finally, the main open questions, as well as current and expected investigation trends are discussed.

Abstract
Primary central nervous system lymphoma (PCNSL) is a rare form of non-Hodgkin lymphoma (NHL) that is restricted entirely to the brain, leptomeninges, eyes, and rarely the spinal cord. It typically presents with focal neurologic symptoms and is characterized by diffuse infiltration of the brain. Corticosteroids are useful for symptomatic treatment but can interfere with definitive pathological diagnosis. PCNSL is radiosensitive and responds to whole-brain radiotherapy. The use of preirradiation high-dose methotrexate-based regimens has significantly improved response rates and patient survival. Longer survival, however, is often marred by devastating neurotoxicity to which the elderly are particularly susceptible. Newer regimens aim to minimize such toxicity while maintaining the survival benefit of combined modality treatment.

Abstract
Primary central nervous system lymphoma (PCNSL) in childhood is very rare. We report a 5-year-old boy who presented with headache and nausea. Magnetic resonance imaging (MRI) showed a faintly enhanced lesion in the left cerebellar hemisphere. MRI-guided biopsy was returned with a histopathological diagnosis of lymphoma. Cranial radiotherapy alone with whole-brain irradiation (30 Gy) followed by a 20-Gy booster to the tumor bed was successful and the patient is alive, well, and in persistent complete remission 14 years post-treatment. This is the only pediatric PCNSL encountered at our institution between 1989 and 2004.

Abstract
Primary central nervous system lymphoma (PCNSL) is a very rare brain tumor in children, and the optimal management and prognosis of such patients have yet to be defined. In this study, the incidence rate, clinical features, diagnosis, and treatment of childhood PCNSL are reviewed. Except for human immunodeficiency virus-related PCNSL, the prognosis for patients with this tumor type is significantly better in children than in adults. In the absence of prospective studies, it is very difficult to determine the true incidence and the best therapeutic strategy for this rare entity. The majority of children with PCNSL, however, can achieve long-term remissions with intensive chemotherapy alone (an estimated 70% 5-year event-free survival rate), and cranial irradiation can be reserved for relapse of the disease. Further progress in the management of childhood PCNSL will require prospective multinational studies.

Abstract
The purpose of this study is to report a rare case of primary meningeal high grade Burkitt-type lymphoma presenting as the first clinical manifestation of acquired immunodeficiency syndrome. A 38-year-old Caucasian man, with a negative past medical history, sought treatment after experiencing global headache for five days. CT-Scan revealed a right front-temporo-parietal hyperdense subdural expansive mass. A craniotomy was performed and a hard white subdural was microsurgically dissected. Some hours after the surgery, the patient developed hemispheric cerebral edema and intracranial hypertension syndrome. Decompressive craniotomy was performed and the patient had an excellent recovery. Screening blood tests diagnosed human immunodeficiency virus infection. Further investigation ruled out systemic diseases. Eleven days after the initial surgery, the patient developed an acute respiratory failure and sepsis, dying on that day. Pathological studies diagnosed Burkitt-type lymphoma.

Abstract
OBJECTIVES Primary central nervous system lymphoma (PCNSL) is a rare pathology and is most often seen in immunodeficient patients. This article presents our casuistic of PCNSL in immunocompetent patients and make a literature review on this issue with focus on recent advances, investigations, and controversies in diagnosis and management of this pathology. MATERIAL AND METHODS Nine patients operated in the last years in our clinics are analysed in relation to sex, age, time of symptoms, procedures and adjuvant treatment. Posteriorly the results are compared with those in the preview literature. RESULTS The age ranged from 44-68 years (middle of 66 years); 62.5% of the patients were female. The mean time of symptoms, when the diagnostic was made, was 3.2 months (range 1-6 months). The most common symptoms were hemiparesis (present in 75% of the patients) headache (37.5%) seizures (25%) and ataxia (25%). The most common localization was the parietal, frontal and temporal lobe surface with 25% of the patients for each localization. Five patients (50%) were treated with stereotactic biopsy, three with surgery (37.5%) and one (12.5%) with both of them. Five patients (62.5%) were submitted to pos-operative radiotherapy as adjuvant treatment. In relation to the histology, the most common cell type was Diffuse B Cells. CONCLUSIONS This study demonstrated that complete surgical resection followed by radiotherapy have shown good results. In opposition to the literature, the authors regard chemotherapy as a secondary line treatment and recommend its use only in some selected cases.

Abstract
Primary CNS non-Hodgkin lymphoma (PCNSL) has been shown to be increasing in incidence. This appears to be a consequence of the increasing population of those older than 65 years of age in whom PCNSL occurs most often. PCNSL often has a favorable response to treatment and aggressive management may result in extended survival and, in a proportion of patients less than 65 years of age, cure. The majority of neuro-oncologist's advocate utilizing high-dose methotrexate (HD-MTX) as a platform for the chemotherapy treatment of these neoplasms. In this review, the literature regarding HDHMTX as a treatment for PCNSL is summarized as are the pharmacological principles of HD-MTX.

Abstract
PURPOSE We analyzed the therapeutic results and prognostic factors of 46 primary central nervous system lymphoma (PCNSL) patients who were treated at twelve institutions in the Tokai district of Japan between 1995 and 1999. We compared the results with those of a Japanese nationwide survey performed in the past. MATERIALS AND METHODS We sent each institution a questionnaire about the state of patients' disease, pathological type, method and doses of radiotherapy, regimen and intensity of chemotherapy, and patients' prognoses. The range of patients' ages was 33 to 93 years (median, 61 years). Thirty-one were men and 15 were women. The most prevalent histology was diffuse large B cell type (33 patients). We used the Kaplan-Meier method to calculate the survival rate and Cox's proportional hazards model to analyze the prognostic factors. RESULTS The five-year cumulative survival rate was 25%, and the median survival time was 22.7 months. The five-year disease-free survival rate was 23%. In monovariate analysis, patients who were both younger than 60 years old and had a WHO performance status (PS) score equal to or less than 2 showed a better survival rate. Furthermore, the patients receiving systemic chemotherapy showed a significantly better local control rate. In addition, patients who received systemic chemotherapy achieved a higher complete remission rate than those not receiving it. However, no factors that significantly influenced survival rate were identified in multivariate analysis. CONCLUSION We demonstrated that the therapeutic outcome of PCNSL patients has recently improved. In particular, patients with good PS showed better local control than those with poor PS. However, we could not identify any significant prognostic factors in PCNSL patients.

Abstract
Primary central nervous system lymphoma (PCNSL) describes a malignant non-Hodgkin's lymphoma (NHL) whose sole site of involvement is the central nervous system (CNS). The diagnosis of PCNSL must be differentiated from systemic NHL with metastasis to the CNS, which usually occurs late in the course of systemic disease. PCNSL accounts for approximately 4% to 7% of primary brain tumors, and its incidence has been increasing since the mid-1970s. Compared with other more common malignant primary brain tumors, PCNSL tends to be more amenable to radiotherapeutic and chemotherapeutic intervention. In this article, the authors review the standard treatment for upfront and recurrent PCNSL.

Abstract
PURPOSE Results of radiation therapy for primary central nervous system lymphoma (PCNSL) were poor in the 1970-1980s, with most reported 5-year survival rates being less than 10%. To investigate whether the prognosis of PCNSL patients treated by radiation alone remains still poor, we investigated the results of radiation monotherapy in the 1990s. METHODS AND MATERIALS We collected data on 132 patients with histologically proven PCNSL treated by radiation alone in the 1990s from three nationwide or regional multiinstitutional studies conducted by the Japanese Society for Therapeutic Radiology and Oncology (JASTRO) Lymphoma Study Group or the Chubu Radiation Oncology Group. Follow-up data were updated as far as possible. Eleven patients who did not complete planned radiotherapy were included. The data were analyzed in relation to patient and tumor characteristics. The median patient age was 63 years, and the World Health Organization performance status (PS) was 3 or 4 in 40% of the patients. Multiple tumors were seen in 34%. Whole-brain irradiation with or without focal boost was used in 92%. The median radiation dose to the tumor site was 50 Gy (range, 8-74 Gy). RESULTS For all 132 patients, the median survival time was 18 months and the 5-year survival rate was 18.0%. For 62 patients with PS 0-3 and aged 16-65 years (i.e., those eligible for the European Organization for Research and Treatment of Cancer 20962 study), the median survival was 26 months and 5-year survival was 24%. The 5-year survival was 25% for patients 63 years old or younger, and 9.8% for those older than 63 years (p = 0.0005). The 5-year survival was 22% for patients with PS 0-2 and 13% for those with PS 3 or 4 (p = 0.0040). Multivariate analysis confirmed the negative influence of higher age on patient prognosis. CONCLUSIONS The results of radiation monotherapy for PCNSL appear to have improved as compared with those reported previously. The results of new treatment should be evaluated in light of this finding. Since most prospective studies on the combined treatment exclude poor PS and high-age patients, the 5-year survival rate of 30% may not be regarded as a marked improvement over radiation alone.

Abstract
We retrospectively analyzed 32 cases of primary central nervous system lymphoma (PCNSL). Five cases were diagnosed in the period 1987-1994, for 27 cases in the period 1995-2002. There were 17 men and 15 women whose median age was 69 years. Three patients were immunodeficient. The commonest symptoms were focal deficit (16 patients) and cognitive/behaviour disturbances (14 patients). Radiologically, a total of 47 contrast-enhancing lesions were observed in 32 patients; 18 patients had deep-seated lesions. All but two patients underwent histological diagnosis following craniotomy (11 patients) and/or stereotaxic biopsy (22 patients); diagnosis was obtained on CSF cytology in one patient with a third ventricle tumour. In the last patient, the diagnosis was based on the finding of marked tumour shrinkage under corticotherapy, despite two negative histological examinations. Treatment included surgical resection (10 patients), chemotherapy (25 patients) and/or radiotherapy (12 patients). According to the therapeutic recommendations of the GELA (Groupe d'Etude des Lymphomes de l'Adulte), 19 patients received at least two courses of high-dose methotrexate; intrathecal chemotherapy was used in 20 patients with methotrexate and/or cytosine arabinoside. Radiation therapy consisted of whole brain irradiation followed by a boost on tumour site. Nine patients received a combined treatment of chemotherapy and radiotherapy. Twelve patients showed rapid progression to death. At the time of last contact, 28/32 patients (88%) had died, all from PCNSL disease or from complications due to its treatment. The median survival time was 13.9 months. We conclude that PCNSL is an increasingly frequent tumour. The diagnosis is obtained by stereotactic biopsy in the majority of cases. The prognosis appears dismal despite an intensive multidisciplinary therapeutic approach.

Abstract
BACKGROUND Neurotoxicity after whole-brain irradiation remains a major problem in the treatment of primary central nervous system lymphoma (PCNSL). To clarify whether whole-brain radiation is necessary for PCNSL, the authors retrospectively analyzed the outcome of patients treated with partial-brain irradiation. METHODS A nationwide survey was performed regarding the treatment of PCNSL. Among 62 institutions surveyed, 7 were identified in which whole-brain irradiation was not necessarily employed. Questionnaires were sent to these institutions and 43 patients who had been treated using partial-brain fields since 1985 were collected. Thirty-two patients had solitary lesions and 11 had multiple lesions. Patterns of recurrence could be identified in 38 patients. RESULTS The cumulative in-field and out-field recurrence rates at 5 years were 57% and 49%, respectively. Of 14 out-field recurrences, 2 occurred at the safety margin of the previous radiation field. The out-field recurrence rate was 45% in patients with a single lesion and 67% in those with multiple tumors (P = 0.79). The out-field recurrence rate was 22% for patients treated with safety margins of > or = 4 cm and 83% for those treated with safety margins of < 4 cm (P = 0.0079). The median survival time and the 5-year survival rate were 28.5 months and 20%, respectively, in the former group of patients and 15 months and 11%, respectively, in the latter group (P = 0.057). CONCLUSIONS Focal radiotherapy with safety margins of < 4 cm appears to be associated with a very high rate of out-field recurrence, but the use of a radiation field with generous safety margins (> or = 4 cm) appears to be worth further investigation.

Abstract
BACKGROUND Reported data regarding intraocular lymphoma (IOL) management are anecdotal. Cases of IOL included in an international multicentre series of 378 immunocompetent patients with primary central nervous system lymphomas (PCNSLs) were reviewed. PATIENTS AND METHODS Staging included slit-lamp examination in 170 patients: IOL was diagnosed in 22 cases (13%). A concomitant brain lesion was detected in 21 cases. Planned treatment was chemotherapy followed by radiotherapy in 13 cases, chemotherapy alone in three and radiotherapy, followed by or not by chemotherapy in five; one patient was not treated. Chemotherapy included high-dose methotrexate in 12 cases. Ten patients received intrathecal chemotherapy. Radiotherapy consisted of whole brain irradiation, followed by or not by a tumour bed boost; ocular irradiation was planned in 15 cases. Irradiation in one patient without brain lesions was limited to the orbits only (50 Gy). RESULTS IOL was positively correlated to systemic symptoms and meningeal disease. Fifteen patients (71%) achieved an objective response; 16 patients experienced a failure (2-year failure-free survival 34+/-10%). Failures involved the eyes in eight cases, with a 2-year time to ocular relapse of 59+/-11%. Ocular failure was less common in patients treated with chemotherapy plus ocular irradiation and was associated with a significantly shorter survival. Seven patients are alive [median follow-up 53 months, 2-year overall survival (OS): 39+/-11%] , five of whom were treated with ocular irradiation. The patient with isolated IOL is alive and disease-free at 14 months. OS of the entire series was similar to that of PCNSL patients with negative slit-lamp examination. CONCLUSIONS IOL is usually associated with concomitant brain disease and shows a survival similar to that of the rest of PCNSLs. Chemotherapy combined with ocular irradiation resulted in better control of ocular disease, which seems to be associated with survival. In view of the potential role of ocular irradiation, the use of chemotherapy alone in phase II trials should be critically reconsidered in PCNSL patients with ocular disease.

Abstract
Primary central nervous system lymphomas (PCNSL) are aggressive malignancies, exhibiting one of the worst prognoses among lymphomas. The best treatment modality for PCNSL has not yet been identified. Several therapeutic questions still remain unanswered, and some methodological pitfalls in clinical trials prevent definitive conclusions from being drawn. In this review, certain aspects of trial design as well as emerging therapeutic guidelines are analyzed, and future perspectives are discussed. In the vast majority of prospective trials, general criteria for treatment of aggressive lymphomas were adopted, choosing primary chemotherapy (CHT) followed by radiotherapy (RT) as therapeutic modality. This strategy produced a five-year survival of 22%- 40% in comparison to the 3%-26% reported with RT alone. Systemic high-dose methotrexate (HD-MTX) seems to be the most effective drug, producing a response rate of 80%-90% and a two-year survival of 60%-65%. To date, the addition of other drugs at conventional doses have not consistently improved outcome. With a few exceptions, any regimen without HD-MTX comprehensively performed no better than RT alone. In combined treatment. RT doses should be decided on the bases of response to primary CHT and the number of lesions, and, until definitive conclusions from well-designed trials are available, RT parameters should follow the widely accepted principles used for other aggressive lymphomas. CHT as exclusive treatment, keeping RT for relapses or persistent disease, appears to be an attractive strategy. However, the worldwide experience with this modality is still limited, and corroborating data are needed. Intrathecal CHT still has not found a defined role in PCNSL management. Preliminary data seem to indicate that adequate meningeal treatment with HD-MTX, but without intrathecal CHT, could also be suitable in positive-cerebrospinal fluid patients. Future efforts should be addressed to identify new active drugs and more efficient CHT combinations, to evaluate the efficacy of high-dose CHT supported by autologous peripheral blood stem cells transplantation, and to clarify the impact of RT delay in complete responders, the usefulness of intrathecal CHT, and the best management for elderly patients. The assessment of impact of treatment on neuropsychological functions and quality of life is a mandatory endpoint in clinical trials.

Abstract
PURPOSE To assess, in a multi-institutional setting, the impact on relapse, survival, and toxicity of adding two cycles of intravenous methotrexate to cranial irradiation for immunocompetent patients with primary CNS lymphoma. PATIENTS AND METHODS Forty-six patients with a median age of 58 years and Eastern Cooperative Oncology Group performance status 0 to 3 were entered onto this phase II study. The protocol consisted of methotrexate 1 g/m(2) on days 1 and 8 followed by cranial irradiation on day 15. A whole-brain dose of 45 Gy was followed by a boost of 5.4 Gy. Intrathecal chemotherapy and spinal irradiation were given only to patients for whom cytologic examination of CSF was positive for CNS lymphoma. The median follow-up time was 36 months, with a minimum potential follow-up of 12 months. RESULTS Median survival was 33 months, with 2-year probability of survival 62% +/- 15% (95% confidence interval). Twenty patients have relapsed. The predominant site of relapse was the brain. Neither performance status nor age was found to influence survival. Six patients developed a dementing illness at a median of 16 months after treatment, and three of these died as a consequence. CONCLUSION A brief course of intravenous methotrexate before cranial irradiation is associated with 2-year and median survival rates superior to those reported for radiotherapy alone and similar to more intensive combined-modality regimens. Neurotoxicity remains an important competing risk for these patients.

Abstract
Five patients at risk for primary central nervous system lymphoma (PCNSL) recurrence were treated with high-dose methylprednisolone (HDMP) to prevent 'trafficking' of malignant lymphocytes into the central nervous system (CNS). HDMP was chosen because of its ability to stabilize the 'blood brain barrier (BBB)'. Three men with newly diagnosed PCNSL, ages 62, 76 and 78y, whose survival was projected to be 6.6 months, began treatment after achieving complete response (CR) to initial radiation therapy alone and survived 27, 37 and 59 months after treatment. In none was death from recurrent disease in CNS but one patient did die of systemic non-Hodgkin's lymphoma (NHL) five years after PCNSL diagnosis. A 20 y old man was treated with HDMP after successful combined modality therapy and is alive 75+ months after initial diagnosis without evidence of disease recurrence. A 34 y old man relapsed after combined modality initial treatment and failed to respond to HDMP when treatment was begun after unsuccessful salvage therapy; he died of disease 12 months after initial diagnosis. There were no treatment complications. The promising results in this pilot study from the basis for a North Central Cancer Treatment Group (NCCTG) 96-73-51, a Phase 2 clinical trial of brain radiotherapy and HDMP for PCNSL patients 70y of age and older, a group of patients at high risk for toxicity from intensive combined modality therapy.

Abstract
In anticipation of a consortium study of methotrexate (MTX) therapy provided to patients with primary central nervous system lymphoma (PCNSL) we have provided intravenous MTX without irradiation therapy to 31 nonimmunosuppressed individuals. Twenty (65%) achieved complete response and 11 (35%) partial response to therapy. For the 31 patients the median survival was 30.43 months with an actuarial median follow-up time of 30.69 months. The 2+ year survival was 63% for all patients and 90% for complete responders. Of 375 drug cycles, grade 3 leukopenia was identified in 3 cycles, mucositis in 6 cycles and delayed drug clearance in 47 cycles. Recurrences included brain (9/20) and/or spinal fluid (2/20). The median Karnofsky scale improved from 40 (10-80) prior to therapy to 90 after treatment. Eleven patients, in complete response for a median of 22+ months after diagnosis were evaluated using 4 instruments that assess Quality of Life Functional Assessment of Cancer Therapy - Brain (FACT-BR) modified, Symptom Questionnaire, Social Adjustment Scale-Self-Report and Problem Solving Inventory. Their psychosocial adjustment, well-being and stress coping abilities were comparable to the normative groups. Further there was no evidence of any MTX-induced, Magnetic Resonance Imaging (MRI)-detected encephalopathy in these individuals and there was preservation of clinical cognition and memory. We conclude that therapy with MTX, without radiation can be used in PCNSL patients without limitations of age or pretreatment Karnofsky scores. Further rates of response and median survival approach those of therapies using multiple drugs and radiation, but with a less likely risk of dementia.

Abstract
Novel efficient and aggressive treatment protocols for primary CNS lymphomas have resulted in an increasing number of long term survivors. Follow up data show that in a substantial fraction of these patients, treatment benefits are overshadowed by neurotoxic sequelae. Neurotoxicity especially affects the older age group, presenting as cognitive dysfunction, ataxia or dementia as a consequence of leukoencephalopathy and brain atrophy. The combination of radiotherapy and chemotherapy seems to be particularly hazardous, though data are too sparse to draw any definite conclusions yet. Long term follow up of patients included in clinical studies therefore should not only evaluate survival or time to tumour progression, but also serial neuropsychometric evaluation and quality of life assessment.

Abstract
PURPOSE To analyze clinical features, treatment results, and prognostic factors of primary central nervous system lymphoma (PCNSL) in Japan, we conducted a nationwide survey. METHODS AND MATERIALS We analyzed 466 patients with histologically proven PCNSL treated between 1985 and 1994 at 62 institutions, including 56 medical schools. RESULTS Patient and tumor characteristics of the 466 patients were not greatly different from those reported previously, except for the relatively high proportion of T-cell lymphoma (8.5%). The median survival time of the 466 patients was 18 months, and the 5- and 10-year survival rates were 15.2% and 8.2%, respectively. Complete response was observed in 63% of evaluable patients, but 64% of the complete responders developed recurrence (77% within the irradiated volume). Among patient- or tumor-related factors, higher age, worse performance status, presence of B symptom, multiple lesions, presence of meningeal dissemination, and elevated lactate dehydrogenase (LDH) level were associated with poorer survival, whereas no significant difference was observed in prognosis with respect to sex, T/B phenotype, or histological subclassification. In 410 patients receiving at least 40 Gy to the tumor, there was no difference in survival with respect to total radiation dose or field. Patients receiving 2 or more cycles of systemic chemotherapy had a slightly longer median survival time (22 months) and higher 5-year survival rate (20%) than those receiving radiotherapy alone (18 months and 17%, respectively), but the difference was not significant (p = 0.13). No chemotherapy protocol appeared to be better than any other. CONCLUSIONS In addition to age and performance status, which are well-known prognostic factors, B symptom, tumor number, presence of meningeal dissemination, and serum LDH level also seemed to influence survival. Higher radiation dose was not associated with better prognosis. The role of chemotherapy could not be clarified because of the use of various protocols, but it seemed that the influence of various prognostic factors is greater than the effect of chemotherapy.

Abstract
We treated 23 patients with primary central nervous system lymphoma with a protocol of conventional radiation up to 55 +/- 5 Gy followed by 4 to 6 cycles of intravenous doxorubicin (30 mg/m2), vincristine (1 mg/m2) and cyclophosphamide (350 mg/m2), and oral prednisolone (8-30 mg/m2) (VEPA chemotherapy) repeated at 2-week intervals. The median age of the 23 patients was 59 years, and the median World Health Organization performance status score was 2. Seventeen patients received 4 or more courses of the chemotherapy, but 6 received only 1 or 2 courses for various reasons. The median survival time for all 23 patients was 25.5 months and their 5-year survival rate was 23%. These values were 34 months and 32%, respectively, for the 17 patients who received 4-6 courses of chemotherapy. After treatment, decline in performance status unaccompanied with tumor recurrence was observed in 44% of the patients; the incidence was apparently higher in older than in younger patients. The survival results obtained with this combined radiochemotherapy regimen appear to be better than those reported in most previous studies of patients treated with radiation alone. Post-irradiation VEPA chemotherapy appears to be worthy of further evaluation.

Abstract
PURPOSE We herein report updated survival and toxicity data on the entire cohort of 53 eligible patients treated on North Central Cancer Treatment Group (NCCTG) protocol 86-72-52, which is now closed. METHODS AND MATERIALS An initial report was published in this journal in 1995. No substantive changes in the conclusions of that report were identified in this analysis. Median survival was 9.6 months for the entire cohort; median survival for the 20 patients who completed the prescribed protocol treatment was 20.7 months. The hematologic and non-hematologic toxicity distributions are virtually the same as those reported in the original paper. RESULTS Results are given for the entire group and for subsets defined by age < or = 60 versus > 60 years, and < 70 versus > or = 70 years of age. CONCLUSIONS No significant differences were observed in any of the outcome variables by age group. There was, however, a nonsignificant suggestion of poorer outcome in those who were > 60 years of age.

Abstract
Failure after first-line treatment was reported in 35-60% of immunocompetent patients with primary central nervous system lymphoma (PCNSL). There are currently no reports focusing on salvage therapy. This review analyses prognostic factors and the efficacy of salvage therapy by focusing on data from papers reporting results of first-line treatment in 355 cases. The study group consisted of 173 patients presenting treatment failure. The interval between failure and death (TTD) was compared for age at relapse (< or =60 vs. >60 years), type of failure (relapse vs. progression), time to relapse (< or =12 vs. >12 months) and salvage treatment (yes vs no). Median TTD was similar in younger and older patients (P = 0.09). Relapsed patients had a longer TTD than patients with progressive disease (P = 0.002). Early relapse led to a shorter TTD than late relapse (P = 0.005). Median TTD was 14 months for patients who underwent salvage therapy and 2 months for untreated cases (P<0.00001). A multivariate analysis showed an independent prognostic role for salvage therapy and time to relapse. Age and type of failure had no predictive value. Salvage therapy significantly improves outcome and, possibly, quality of life. As many different treatments were used conclusions cannot be made regarding an optimal treatment schedule.

Abstract
The aim of this study is to determine the diagnostic value of cerebrospinal fluid (CSF) soluble CD27 (sCD27) as a tumor marker for primary central nervous system lymphoma (PCNSL). We examined sCD27 levels in CSF obtained from various types of brain tumor patients. Forty-two patients were studied (including 12 PCNSL patients) who had not received any therapy for their tumors. In all PCNSL cases, CSF sCD27 levels were more than 15 U/ml (median 84.5 U/ml, range 17-484 U/ml) and in other brain tumor cases, CSF sCD27 levels were all less than 15 U/ml. Our data suggest that CSF sCD27 levels are useful to distinguish PCNSL from other brain tumors.

Abstract
PURPOSE To assess prognostic factors and treatment modalities of patients with primary central nervous system lymphoma (PCNSL) in terms of response rates, patterns of failure and overall survival. METHODS AND MATERIALS Sixty-two patients presenting with PCNSL between 1982 and 1994 at Peter MacCallum Cancer Institute with no evidence of human immunodeficiency virus infection were included in the study. Their median age was 60 years; World Health Organisation (WHO) performance status was > or = 2 in 85%. All patients were planned to receive whole brain irradiation; 7 also received spinal irradiation. The median planned dose to the target volume was 50.4 Gy. Twenty patients were planned to receive chemotherapy as well. Patients were followed up to June 20, 1995, giving a median follow-up for 14 surviving patients of 5.4 years, range 0.3 to 10.2 years. RESULTS The clinical response rate to treatment was 77% [95% confidence interval (CI) 65 to 87%]. The estimated median overall survival was 20.6 months (CI 12.4 to 33.4 months). On univariate analysis male gender, age <60 years, WHO performance status < or = 1, treatment to the target volume > or = 45 Gy, and treatment with additional chemotherapy, were associated with a significantly better overall survival (p < 0.05). On multivariate analysis only age and performance status remained significant prognostic variables. Relapse involved the central nervous system or cerebrospinal fluid (CSF) in all patients with known sites of relapse except three who had ocular relapse only. There was a low incidence of relapse in the initial brain site (23% of known cases) and a high incidence (50%) of CSF/spinal cord relapse. Of 48 deaths, 15 were related to initial or subsequent treatment. CONCLUSIONS Patient outcome is strongly influenced by age and performance status. Studies suggesting better survival for patients treated with chemoradiation may reflect patient selection rather than treatment variables. Optimal management remains to be defined. The high CSF/spinal relapse rate deserves particular attention.

Abstract
The increased incidence of second malignancies among cancer survivors is well documented. Thus, differential diagnosis between metastatic spread from a prior malignancy and the occurrence of a new neoplasm should be considered. This is particularly difficult for brain lesions due to their poor prognosis that often discourages diagnostic work-up. In some cases diagnosis of a second primary neoplasm, such as primary central nervous system lymphomas (PCNSL), could change the therapeutic management and the prognosis. About 8% of PCNSL occurs as a second malignancy. Homogeneous and intense tomographic enhancement, deep location of lesions and dramatic response to corticosteroids are suggestive for PCNSL and should be carefully considered before the start of treatment for cerebral lesions. Prognosis and standard management of brain metastases and PCNSL are almost completely different. In addition, while treatment of brain metastases often has a palliative purpose the goal in PCNSL treatment is the cure. Four patients with PCNSL as a second malignancy are reported and literature is reviewed. Diagnosis of PCNSL changes the strategy of treatment which could have a critical therapeutic and prognostic impact.

Abstract
BACKGROUND The optimal treatment for primary central nervous system lymphomas (PCNSL) has not been defined. PATIENTS AND METHODS Therapeutic results of 1180 immunocompetent patients (pts) with PCNSL reported in 50 series published in English between 1980 and 1995 were analysed. The impact on survival of age, treatment strategy, radiation field and doses, systemic and intrathecal chemotherapy (CHT) and treatment sequence was evaluated. RESULTS Univariate analyses showed a longer survival in pts of < or = 60 years (P < 0.00001): pts treated with > 40 Gy to whole brain (WB) (P = 0.02): pts receiving > 50 Gy to the tumor bed after a WB dose > 40 Gy (P = 0.02): pts submitted to a combined treatment as opposed to CHT alone (P = 0.007) or radiotherapy alone (P < 0.00001): pts receiving CHT followed by radiotherapy rather than in the reverse sequence (P = 0.05); pts treated with high-dose methotrexate (HDMTX) (P = 0.04) and pts receiving intrathecal CHT (P = 0.03). Multivariate analysis confirmed the independent prognostic value of age, WB dose, HD-MTX and intrathecal CHT. CONCLUSIONS Current data confirm the prognostic value of age and appear to support the use of systemic CHT consisting of HD-MTX and intrathecal drug administration followed by 41-50 Gy to WB and > 50 Gy to the tumor bed in the treatment of PCNSL in immunocompetent pts.

Abstract
Prior studies have suggested that pre-irradiation methotrexate (MTX)-based chemotherapy improves duration of response and survival in primary central nervous system lymphoma (PCNSL). To circumvent the potential emergence of drug resistance, we combined high-dose MTX with agents highly active against systemic lymphoma. Patients received three week cycles of CHOD (cyclophosphamide 750 mg/m2, doxorubicin 50 mg/m2, and vincristine 1.4 mg/m2 [2 mg maximum] on day 1; dexamethasone 10 mg/m2 days 1-5), and MTX (3.5 gm/m2) with leucovorin rescue on day 8 (or on recovery from the CHOD nadir). Whole brain irradiation (WBRT) was planned after at least three cycles. Eighteen patients were treated. Complete responses were seen in eleven patients, and partial responses in three. Four progressed during therapy, three succumbing to progressive disease and one subsequently responding to WBRT. Response duration was 37.5 months in those responding to therapy. The time to progression for all eighteen patients was 19.5 months. Medial survival was 25.5 months. Disease-free survival was 50% at 38 months in MCHOD responders. Grade 3 or 4 myelotoxicity was seen in 19 of 50 cycles. There were three instances of neutropenic fever, three of azotemia, two of deep vein thrombosis, and one each of community-acquired pneumonia, intracranial hemorrhage, superior vena cava syndrome, and hepatotoxicity. Late radiation-related toxicities were seen in two patients. Pre-irradiation MCHOD has activity against PCNSL, but appears to be no better than MTX monotherapy and has greater toxicity.

Abstract
UNLABELLED We conducted a Phase II study of PROMACE-MOPP and intrathecal (IT) therapy followed by cranial radiation in 7 patients (4 male, 3 females) with diffuse large cell lymphomas (including one T cell) involving the central nervous system (CNS). Median age was 47 years (range, 25-78). Median performance status was 2 (range, 2 to 3). Two patients had positive CSF cytology. No patients had prior chemotherapy or radiotherapy. Treatment consisted of PROMACE (cyclophosphamide 650 mg/m2, etoposide 120 mg/m2 days 1 and 8, methotrexate (MTX) 1.5 g/m2 and folinic acid 50 mg/m2 (x 5) day 15, and prednisone 60 mg/m2 days 1-14) x 3-4 courses. MOPP consisted of mustargen 6 mg/m2 and vincristine 1.4 mg/m2 days 1 and 8, procarbazine 100 mg/m2 and prednisone 40 mg/m2 po days 1-14 x 3-4 courses. IT drugs were MTX 20 mg and hydrocortisone 20 mg day 1 and cytosine arabinoside 100 mg day 8, courses 2 to 6, or more frequently if CSF cytology was positive. Following MOPP, 4000 cGy whole brain radiation (XRT) and 2000 cGy boost was given. Response was evaluated before XRT. Two patients declined XRT, 3 declined MOPP and 2 declined IT drugs. Two patients had extracerebral disease and 5 were primary CNS lymphomas. Response after PROMACE was CR: 3 patients; PR 2: stable 1. One patient, with extracerebral disease, experienced PR in the abdomen and CR by CT scan in the brain, but had persistent positive CSF cytology. This patient died from pneumocystis pneumonia 10 weeks after her last CSF cytology and 17 weeks after her diagnosis. After PROMACE +/- MOPP 6 patients experienced CR's. Median (range) survival was 100 (17-334) weeks, with 1 patient lost to follow up at 32 weeks. Toxicity included febrile neutropenia; 6 patients; pneumocystis pneumonia: 1 (fatal); thrombocytopenia; 5; stomatitis: 3; diarrhea; 2; nausea; 3. CONCLUSION This regimen is active in the treatment of CNS lymphomas, although toxicity is substantial.

Abstract
BACKGROUND The high incidence of local failure and the lack of evidence of systemic dissemination of primary central nervous system lymphoma (PCNSL) has led some authors to conclude that complete staging with extensive tests is not necessary in patients with a lymphomatous cerebral mass who present with a focal neural syndrome. Moreover, De Angelis emphasizes that there is no report in the literature of systemic lymphoma presenting as a cerebral mass lesion, whereas others conclude that an extensive systemic evaluation is unnecessary or that the staging should be limited to physical examination, routine blood studies, and a chest radiography. METHODS In 16 PCNSL patients observed between 1982 and 1992, we found two patients showing systemic involvement of lymphoma after staging workup with chest X-ray, total body computerized tomographic (CT) scan, cerebrospinal fluid cytology examination, and bone marrow biopsy. In one patient, a CT abdominal scan showed retroperitoneal and pelvic lymphonodal involvement, whereas in the second patient, bone marrow biopsy was positive. These systemic onsets were found no later than 2 months after the diagnosis of central nervous system involvement, which is sufficient time to conclude that these locations were present at the diagnosis of the cerebral mass. RESULTS In the present study, complete staging demonstrated widespread dissemination (lymph nodes or bone marrow) in two patients with initial neurologic symptoms and a cerebral mass lesion. CONCLUSIONS In our experience, complete staging allowed detection of systemic lymphoma in two patients initially considered to have PCNSL.

Abstract
A retrospective analysis of 23 non-immune compromised patients with primary central nervous system lymphoma (PCNSL) is reported. The patients consist of 14 males and 9 females and the median age is 50 years. Most patients presented with focal neurological deficits or symptoms of increased intracranial pressure (ICP) due to mass effects around the periventricular area. However, there were four cases of diffuse type, one case of intramedullary tumour, and four cases with rapid disease progression. All the patients underwent histological confirmation by craniotomy (16 cases) or stereotactic biopsy (7 cases). The radiation therapy started after histological diagnosis in all and 6 cases received additional chemotherapy. The median survival after diagnosis of overall patients was 23 months. Six patients are in disease free status at a mean of 35 months follow-up. The uni- and multi-variative risk analysis revealed five favourable factors on survival: (1) age less than 60 years (0.05 < p < 0.1); (2)pre-operative Karnofsky performance scale (KPS) > or = 70 (p < 0.05); (3) symptom duration over four weeks (p < 0.05); (4) radiation dosage > or = 5500 cGy (p < 0.05); (5)absence of malignant cells in cerebrospinal fluid (CSF) (p < 0.05). The most frequent site of recurrence was the local area as shown in seven cases out of 11 recurrent cases. But six patients had diffuse recurrence (4 cases), systemic recurrence (2 cases), and drop metastasis (1 case). Although the recurred PCNSL had rapid progression and a grave prognosis, aggressive treatment prolonged the postrecurrence survival time significantly. Our experience suggests that 1) there are various clinical and radiological presentations and progressions of the disease; 2) treatment method should be decided along with the clinical presentation, progression of disease, and prognostic factors; 3) early diagnosis and early detection of recurrence enable the start of definitive treatment when the medical condition is still satisfactory.

Abstract
This synthesis of the literature on radiotherapy for non-Hodgkin's lymphomas is based on 158 scientific articles, including 16 randomized studies, 18 prospective studies, and 90 retrospective studies. These studies involve 14,137 patients. Non-Hodgkin's lymphomas are highly radiosensitive, and local recurrence following radiotherapy is unusual. Radiotherapy probably cures approximately 50% of both low-grade and high-grade malignant NHL at stage I. Involved field is apparently sufficient, however, higher doses are required for high-grade malignant lymphomas. Chemotherapy is recommended for stage II. Consolidation radiotherapy after chemotherapy may increase the number of complete remissions. The value of adjuvant radiotherapy has not been confirmed. Radiotherapy plays a limited role at stages III and IV. Radiotherapy is clearly indicated for extranodal localized disease in the skin and in the orbit of the eye. It is important to identify groups and subgroups in whom radiotherapy alone is sufficient, ie, the risk for distant recurrence is small. MALT lymphoma belongs to this group. Radiotherapy is often valuable in palliative situations.

Abstract
A retrospective series of 13 immunocompetent patients with histological diagnosis of primary central nervous system lymphoma (PCNSL) is presented. The series was divided into Group A, 6 patients treated with radiotherapy alone, and Group B, 7 patients treated with chemotherapy and radiotherapy. Clinicopathological patterns were similar for the two groups. In Group A, 4 patients achieved complete remission after radiotherapy (45-59.4 Gy) but relapsed within 9 months and died within 21 months of diagnosis. 4 Group B patients received chemotherapy followed by radiotherapy, and three who received a methotrexate-containing regimen are alive and disease-free at 34, 42 and 45 months, while the fourth died after 11 months. The other 3 subjects in this group were treated with radiotherapy followed by chemotherapy, and died within 15 months of diagnosis. Although radiotherapy is the standard treatment, chemotherapy has potentially an important role in the management of PCNSL. The sequence of combined treatment could be crucial to improvement of outcome.

Abstract
PURPOSE Results of multiple radiation, chemotherapy, and combined treatment trials have shown that the fate of primary central nervous system lymphoma (PCNSL) patients is very different from that of patients with similarly treated systemic IE non-Hodgkin's lymphoma. This study was designed to improve the survival of PCNSL patients by the use of combined initial therapy. METHODS AND MATERIALS Forty-six eligible primary PCNSL patients were treated with whole brain irradiation and adjuvant chemotherapy consisting of preirradiation cyclophosphamide-adriamycin-vincristine-prednisone (CHOP) and postirradiation high-dose cytosine arabinoside (HDAC) as part of an ongoing Phase II Mayo/North Central Cancer Treatment Group/Eastern Cooperative Oncology Group (M/NCCTG/ECOG) intergroup effort, which opened in April 1986. RESULTS This cohort consisted of 23 men and 23 women with median age 63.5 years (range 24 to 75 years). Only 5% were under age 40; 36% were age 40 to 59, 37% were age 60 to 69, and 22% were age 70 and over. Forty-six percent had good performance scores of ECOG 0-1 at time of study entry. Forty-six patients were evaluable for treatment outcome as of October 6, 1993. Of these, 10 were still alive. Estimated median survival and 21-month survival were 45.3 weeks and 29%, respectively. There were four early deaths ranging from Day 9 to Day 15 (three drug-related, one from other complications), and two CHOP responders died at 32 and 35 days, soon after Cycle 2 of CHOP (one probably drug-related, one from other complications). There was no significant difference in survival according to baseline performance status. However, survival was consistently worse for patients > 60 years old than for the younger patients (< or = 60 years). With deaths recorded for 21 of 21 older patients, but only 9 of the 14 younger patients, 21-month survival for older vs. younger was 14 vs. 50% based on the 35 patients who entered the study at least 21 months ago (p = 0.0365). Of the 46 patients evaluable for response, 63% had objective remissions on CHOP and another 20% remained stable. CONCLUSION Combined modality therapy in this study did not produce an overall survival advantage in treating PCNSL. The 50% 21-month survival of younger patients may be a reflection of age only.
