Abstract
Metastasis to the central nervous system (CNS), including neoplastic meningitis (NM), is a devastating complication of systemic cancer. With the improved survival of cancer patients, the incidence of CNS metastasis is rising, especially among those with breast or lung carcinoma. New therapies that effectively treat these primary tumors outside of the CNS have underscored the significance of CNS metastases; they have become a significant clinical issue and a therapeutic challenge. This review discusses clinical situations in which treatment or chemoprophylaxis of CNS metastases and NM from breast or lung cancer may play an important role. Potential clinical trials to assess these assumptions also will be proposed.

Abstract
Acute lymphoblastic leukemia (ALL) 5-year survival rates are approaching 90% in children and 50% in adults who are receiving contemporary risk-directed treatment protocols. Current efforts focus not only on further improving cure rate but also on patient quality of life. Hence, all protocols decrease or limit the use of cranial irradiation as central nervous system (CNS)-directed therapy, even in patients with high-risk presenting features, such as the presence of leukemia cells in the cerebrospinal fluid (even resulting from traumatic lumbar puncture), adverse genetic features, T-cell immunophenotype, and a large leukemia cell burden. Current strategies for CNS-directed therapy involve effective systemic chemotherapy (eg, dexamethasone, high-dose methotrexate, intensive asparaginase) and early intensification and optimization of intrathecal therapy. Options under investigation for the treatment of relapsed or refractory CNS leukemia in ALL patients include thiotepa and intrathecal liposomal cytarabine. CNS involvement in non-Hodgkin lymphoma (NHL) is associated with young age, advanced stage, number of extranodal sites, elevated lactate dehydrogenase, and International Prognostic Index score. Refractory CNS lymphoma in patients with NHL carries a poor prognosis, with a median survival of 2 to 6 months; the most promising treatment, autologous stem cell transplant, can extend median survival from 10 to 26 months. CNS prophylaxis is required during the initial treatment of NHL subtypes that carry a high risk of CNS relapse, such as B-cell ALL, Burkitt lymphoma, and lymphoblastic lymphoma. The use of CNS prophylaxis in the treatment of diffuse large B-cell lymphoma is controversial because of the low risk of CNS relapse ( approximately 5%) in this population. In this article, we review current and past practice of intrathecal therapy in ALL and NHL and the risk models that aim to identify predictors of CNS relapse in NHL.

Abstract
BACKGROUND AND OBJECTIVE Central nervous system (CNS) involvement in patients diagnosed with acute leukemias (AL) is an uncommon complication with poor prognosis. The indication and the schedules of prophylaxis and treatment of CNS involvement in AL are not homogenous among countries and within the same country. The aim of this prospective longitudinal study was to analyze and report the practice of CNS prophylaxis and treatment in patients with AL in Spain. PATIENTS AND METHOD Prospective study conducted from June 2005 to June 2006. Adult patients (> or = 18 yr.) diagnosed with AL who received CNS prophylaxis or treatment were consecutively included through online registration. RESULTS 265 patients from 32 hospitals were included. Mean (standard deviation) age was 44 (16) yr. and 133 (50%) were males. For acute lymphoblastic leukemia patients (n = 158), CNS therapy was given to 12 cases (10 at diagnosis and 2 at relapse) and consisted of triple intrathecal therapy (TIT, methotrexate, cytarabine and hydrocortisone) in 11 and liposomal depot cytarabine in one. CNS prophylaxis (n = 146) consisted of TIT in 135 cases, intrathecal methotrexate in 7, intrathecal cytarabine in 2 and intrathecal liposomal depot cytarabine in 2. No cranial irradiation either for prophylaxis or therapy was given in any case. In acute myeloblastic leukemia patients (n = 107), CNS therapy was administered to 17 cases (9 at diagnosis and 8 at relapse). Intrathecal therapy consisted of TIT in 11, intrathecal liposomal depot cytarabine in 5 and intrathecal cytarabine in one. One patient also received craniospinal irradiation. CNS prophylaxis (n = 90) consisted of TIT in 68 cases and intrathecal methotrexate in 22. CONCLUSIONS In Spain, the patterns of CNS prophylaxis and therapy for AL are homogeneous. TIT was the most frequent schedule for CNS prophylaxis and therapy. The lack of use of cranial or craniospinal irradiation and the administration of new drugs (i.e.: liposomal depot cytarabine) for CNS therapy and prophylaxis is of note.

Abstract
BACKGROUND: Leptomeningeal metastasis (LM) is a devastating complication of advanced cancer. Despite aggressive therapy survival is very poor. METHODS: Data of all breast cancer patients with LM were retrospectively analyzed (n = 27). RESULTS: Median survival was 9 weeks. Patients with contrast-enhancing meningeal lesions (n = 11) detected by MRI had a median survival of 33 weeks versus 8 weeks for patients without contrast-enhancing lesions (n = 9; p = 0.0407). Patients who received systemic chemotherapy (n = 18) had a median survival of 15 weeks versus 7 weeks (n = 9; p = 0.0106). Patients undergoing radiotherapy (n = 8) had a median survival of 17 weeks as compared to 5 weeks for patients without radiotherapy (n = 18; p = 0.0188). In a multiple Cox regression analysis, lack of systemic therapy (hazard ratio, HR 89.5; p = 0.002) and negative hormone receptor status (HR 4.2; p = 0.027) emerged as significant main risk factors, together with contrast-enhancing lesion as effect modifier for systemic therapy (p = 0.03). CONCLUSION: Contrast-enhancing meningeal lesions, systemic therapy, and radiotherapy were significantly associated with longer survival. Patients with contrast-enhancing lesions who were treated systemically had the longest survival. Evidence is increasing that systemic therapy plays an important role and should be applied in breast cancer patients with LM.

Abstract
To determine the therapeutic efficacy (13-week and 26-week CNS progression-free survival [PFS], response rate, and overall survival) and safety of intraventricular (IVent) topotecan in patients with neoplastic meningitis (NM), we conducted a phase II, open-label, nonrandomized, single-arm trial of IVent topotecan in patients with NM using 400 mug of topotecan IVent twice weekly for 6 weeks, followed by evaluation with imaging, cerebrospinal fluid (CSF), and physical examinations. In the absence of disease progression, patients were then treated with IVent topotecan weekly for 6 weeks, twice monthly for 4 months, and monthly thereafter. Sixty-two patients (23 males and 39 females) were enrolled from April 2001 through March 2006. Median age and KPS at enrollment were 56 (range 5-83) and 80 (range 60-100), respectively. Primary cancers included breast (19), lung (13), CNS (14), and others (16). Forty patients (65%) completed the 6-week induction period, among whom 13 (21%) had CSF clearance of malignant cells. Kaplan-Meier estimates of PFS at 13 and 26 weeks were 30% (95% confidence interval [CI], 20%-45%) and 19% (95% CI, 11%-34%). Overall median survival (50 deaths) was 15 weeks (95% CI, 13-24 weeks). The most common side effect was chemical meningitis in 32% of patients (5% grade 3); 32% experienced no drug side effects. IVent topotecan is well tolerated, but provides no added benefit over other IVent therapies. Because of its modest side effect profile, combining IVent topotecan with other IVent or systemic interventions should be considered.

Abstract
INTRODUCTION This review was produced from the workshop on primary central nervous system lymphoma (PCNSL) at the European Cancer Conference (ECCO 13) in Paris in 2005. It covers the presentation and biological features of the disease (Professor Khe Hoang-Xuan). The role of chemotherapy, including the management of intraocular lymphoma and the use of high dose chemotherapy followed by autologous stem cell transplantation for PCNSL, is discussed (Dr. Andres Ferreri) as well as controversies in the use of whole brain radiotherapy (WBRT) after chemotherapy (Dr. Michele Reni). The topics covered with discussants at the workshop are also summarised. CONCLUSION The imaging of the brain and the histopathology including detailed immunohistochemistry is of vital importance in making an accurate diagnosis of the disease and understanding the extent of spread of the disease in the CNS. The importance of high dose methotrexate (HDMTX; dose > or = 1g/m(2)), as the most active drug in the treatment of PCNSL, is stressed. The authors recommend that HDMTX alone or in combination with other active chemotherapy agents should be used to treat PCNSL followed by whole brain radiotherapy (WBRT) unless contraindicated because of the advanced age of the patient and existing cognitive impairment. Only published protocols should be used unless the patient is to be offered a trial that has either national or international support. Baseline neuropsychological tests should be carried out before treatment and repeated during and after treatment. The risks of cognitive impairment associated with the disease, with methotrexate - containing chemotherapy and with whole brain radiotherapy should be explained to patients and relatives when obtaining informed consent. Long-term survival, with current treatment regimes, is possible with PCNSL but this appears limited to patients less than 60 years of age at presentation (mostly patients less than 50 years of age).

Abstract
Lamellar liposome technology has been used for several decades to produce sustained-release drug formulations for parenteral administration. Multivesicular liposomes are structurally distinct from lamellar liposomes and consist of an aggregation of hundreds of water-filled polyhedral compartments separated by bi-layered lipid septa. The unique architecture of multivesicular liposomes allows encapsulating drug with greater efficiency, provides robust structural stability and ensures reliable, steady and prolonged drug release. The favourable characteristics of multivesicular liposomes have resulted in many drug formulations exploiting this technology, which is proprietary and referred to as DepoFoam. Currently, two formulations using multivesicular liposome technology are approved by the US FDA for clinical use, and many more formulations are at an experimental developmental stage. The first clinically available formulation contains the antineoplastic agent cytarabine (DepoCyt) for its intrathecal injection in the treatment of malignant lymphomatous meningitis. Intrathecal injection of DepoCyt reliably results in the sustained release of cytarabine and produces cytotoxic concentrations in cerebrospinal fluid (CSF) that are maintained for at least 2 weeks. Early efficacy data suggest that DepoCyt is fairly well tolerated, and its use allows reduced dosing frequency from twice a week to once every other week and may improve the outcome compared with frequent intrathecal injections of unencapsulated cytarabine. The second available formulation contains morphine (DepoDur) for its single epidural injection in the treatment of postoperative pain. While animal studies confirm that epidural injection of DepoDur results in the sustained release of morphine into CSF, the CSF pharmacokinetics have not been determined in humans. Clinical studies suggest that the use of DepoDur decreases the amount of systemically administered analgesics needed for adequate postoperative pain control. It may also provide superior pain control during the first 1-2 postoperative days compared with epidural administration of unencapsulated morphine or intravenous administration of an opioid. However, at this timepoint the overall clinical utility of DepoDur has yet to be defined and some safety concerns remain because of the unknown CSF pharmacokinetics of DepoDur in humans. The versatility of multivesicular liposome technology is reflected by the many agents including small inorganic and organic molecules and macromolecules including proteins that have successfully been encapsulated. Data concerning many experimental formulations containing antineoplastic, antibacterial and antiviral agents underscore the sustained, steady and reliable release of these compounds from multivesicular liposomes after injection by the intrathecal, subcutaneous, intramuscular, intraperitoneal and intraocular routes. Contingent on the specific formulation and manufacturing process, agents were released over a period of hours to weeks as reflected by a 2- to 400-fold increase in elimination half life. Published data further suggest that the encapsulation process preserves bioactivity of agents as delicate as proteins and supports the view that examined multivesicular liposomes were non-toxic at studied doses. The task ahead will be to examine whether the beneficial structural and pharmacokinetic properties of multivesicular liposome formulations will translate into improved clinical outcomes, either because of decreased drug toxicity or increased drug efficacy.

Abstract
Among several promising new drug-delivery systems, liposomes represent an advanced technology to deliver active molecules to the site of action, and at present several formulations are in clinical use. Research on liposome technology has progressed from conventional vesicles ("first-generation liposomes") to "second-generation liposomes", in which long-circulating liposomes are obtained by modulating the lipid composition, size, and charge of the vesicle. Liposomes with modified surfaces have also been developed using several molecules, such as glycolipids or sialic acid. A significant step in the development of long-circulating liposomes came with inclusion of the synthetic polymer poly-(ethylene glycol) (PEG) in liposome composition. The presence of PEG on the surface of the liposomal carrier has been shown to extend blood-circulation time while reducing mononuclear phagocyte system uptake (stealth liposomes). This technology has resulted in a large number of liposome formulations encapsulating active molecules, with high target efficiency and activity. Further, by synthetic modification of the terminal PEG molecule, stealth liposomes can be actively targeted with monoclonal antibodies or ligands. This review focuses on stealth technology and summarizes pre-clinical and clinical data relating to the principal liposome formulations; it also discusses emerging trends of this promising technology.

Abstract
INTRODUCTION Cytarabine liposome injection (DepoCyt), a sterile suspension of the antimetabolite cytarabine, encapsulated into multivesicular, lipid-based particles, has been developed to improve the treatment of neoplastic meningitis (NM) through sustained release of cytarabine. The objective of this study was to determine the pharmacokinetics (PK) of cytarabine after intrathecal administration of 50 mg encapsulated cytarabine (DepoCy) in patients with neoplastic meningitis up to 336 h (14 days) after dosing. METHODS This was an open-label study wherein two 50-mg doses of DepoCyt were administered 14 days apart via the intraventricular (IVT) route or by lumbar puncture (LP). Cerebrospinal fluid (CSF) samples were collected from eight adult patients at various times up to 14 days after each dose. Plasma samples were also collected within the same time period. CSF samples were analyzed for unencapsulated (free) and encapsulated cytarabine and the cytarabine metabolite, ara-U. Plasma samples were analyzed for free cytarabine and ara-U. The limit of detection was 0.003 microg/mL cytarabine and 0.016 microg/ml for ara-U. RESULTS The concentration of free and encapsulated cytarabine in the ventricular and lumbar CSF ranged from 0.01 to 1500 microg/mL and were detectable up to 14 days post-dosing. Free cytarabine concentrations in plasma were only sporadically detectable. CSF and plasma concentrations of ara-U were low in all samples. CONCLUSIONS The administration of intrathecal encapsulation cytarabine prolongs sustained tumor exposure to cytotoxic concentrations of cytarabine (>0.02 microg/ml) with a slow continuous release of cytarabine from the DepoFoam particles, so drug exposure is prolonged over time, resulting in lower peak cytarabine levels and a longer duration of exposure compared with standard cytarabine (Ara-C).

Abstract
Long-term survival is occasionally observed in patients with neoplastic meningitis (NM) accompanying breast cancer (13% one-year and 6% 2-year survival), melanoma, and lymphoma, but in general the survival of most patients is short and averages only 3 to 4 months. The incidence of NM appears to be increasing, in part due to earlier detection by magnetic resonance imaging (MRI), and in part due to development of more effective therapies for systemic cancer, which has resulted in a larger subset at risk for late-stage development of this complication. Survival of NM patients is negatively affected by concomitant progression of systemic disease despite multiple prior therapies. However, there are certain prognostic factors that have been identified as "favorable" in retrospective series, including age less than 60 years, long symptom duration, controlled systemic disease, Karnofsky performance status (KPS) > or =70, lack of encephalopathy or cranial nerve deficits, low initial cerebrospinal fluid (CSF) protein level, history of breast primary tumor, and lack of evidence of CSF compartmentalization or bulky meningeal disease as determined by CSF flow studies. Standard treatment has traditionally involved radiotherapy (RT) to sites of symptomatic or bulky disease, as detected by neuroimaging, and in selected patients, the administration of intrathecal, intraventricular, or systemic chemotherapy. However, treatment remains palliative and many patients and physicians choose supportive care only. Future hope is provided by studies that have improved our understanding of the disease pathogenesis, have identified prognostic variables associated with outcome, and have provided new therapeutic approaches, such as administration of high-dose systemic chemotherapy and investigations of novel therapeutic agents.

Abstract
Brain and leptomeningeal metastases from breast cancer carry a poor prognosis and are often less responsive to systemic therapy. It is often thought that systemic therapy has a minimal role in the management of central nervous system (CNS) metastases because of the impermeability of the blood-brain barrier. However, treatments directed to the CNS such as radiation or intrathecal chemotherapy are not effective in managing concurrent non-CNS metastases. We report the long-term control of a woman receiving capecitabine with brain and leptomeningeal metastases. After 3.7 years of capecitabine therapy after whole-brain radiation, the patient remains without neurologic symptoms or deficits, has no evidence of disease on neuroimaging studies, but has a persistent positive cytology. This case report demonstrates that, in principle, systemic therapy can provide long-term complete responses for some patients with CNS metastases. The significance of persistent circulating tumor cells in the CNS in patients without evidence of disease is unclear but should be investigated further.

Abstract
Neoplastic meningitis is a complication of the CNS that occurs in 3-5% of patients with cancer and is characterised by multifocal neurological signs and symptoms. Diagnosis is problematic because the disease is commonly the result of pleomorphic manifestations of neoplastic meningitis and co-occurrence of disease at other sites. Useful tests to establish diagnosis and guide treatment include MRI of the brain and spine, cerebrospinal fluid (CSF) cytology, and radioisotope CSF flow studies. Assessment of the extent of disease of the CNS is of value because large-volume subarachnoid disease or CSF flow obstruction is prognostically significant. Radiotherapy is an established and beneficial treatment for patients with neoplastic meningitis with large tumour volume including parenchymal brain metastasis, sites of symptomatic disease, or CSF flow block. Because neoplastic meningitis affects the entire neuraxis, chemotherapy treatment can include intra-CSF fluid (either intraventricular or intralumbar) or systemic therapy. Most patients (>70%) with neoplastic meningitis have progressive systemic disease and consequently treatment is palliative and tumour response is of restricted durability. Furthermore, as there is no compelling evidence of a survival advantage with aggressive multimodal treatment, future trials need be done to determine the effect of treatment on quality of life and control of neurological symptoms.

Abstract
Neoplastic meningitis is a feared complication in cancer patients, the median survival ranging from some weeks to a few months. Management is palliative and aims to provide symptoms relief while delaying neurological deterioration. Intrathecal methotrexate and/or cytarabine is the most widely used treatment in such clinical situations. These drugs are administered 2 or 3 times a week--a circumstance that is both bothersome for the patient and time-costly for the medical personnel. Liposomal cytarabine is a sustained-release cytarabine formulation specifically developed for the treatment of neoplastic meningitis. Its administration on a twice-weekly basis ensures sustained cytotoxic drug concentrations in cerebrospinal fluid. Controlled clinical trials have shown liposomal cytarabine to be equally or more effective than the classical treatment for neoplastic meningitis. In lymphomatous meningitis, liposomal cytarabine offers superior response rates, improved patient quality of life, and a prolongation of the time to neurological progression. When the cause of meningitis is a solid tumor, liposomal cytarabine prolongs the time to neurological progression and improves quality of life. These observations indicate that DepoCyte is a convenient treatment for patients with neoplastic meningitis, due to its efficacy and easy of administration characteristics.

Abstract
Treatment of leptomeningeal metastases is multifaceted and includes symptomatic therapy, intrathecal and systemic chemotherapy, and radiotherapy. As the majority of patients have widespread incurable systemic tumor, treatment is predominantly palliative; however, some patients with leukemia, lymphoma or breast cancer may have prolonged remissions and the possibility of cure.

Abstract
Among several drug delivery systems, liposomal encapsulated anti-cancer agents represent an advanced and versatile technology. Several formulations of liposomal anthracyclines are approved, e.g. for the treatment of metastatic breast cancer (pegylated and non-pegylated liposomal doxorubicin) or AIDS-related Kaposi's sarcoma (pegylated liposomal doxorubicin and liposomal daunorubicin). Meanwhile, virtually all anti-cancer drugs have been encapsulated in liposomes using different technologies. This review will summarize preclinical and clinical data of approved and exemplary emerging liposomal anti-cancer agents.

Abstract
Current therapy for leptomeningeal metastases is predominantly palliative. In an effort to improve disease control and patient outcome, new strategies are being developed to target the cerebrospinal space. These include new intrathecal formulations of systemic chemotherapy as well as the development of radiolabeled immunoconjugates and antitumor antibodies. Furthermore, there is debate as to the optimal strategy of drug delivery for leptomeningeal tumor.

The relevance of intraventricular chemotherapy for leptomeningeal metastasis in breast cancer: a randomised study. Eur J Cancer 2004; 40:2726-33.

Abstract
To assess the benefit of intraventricular chemotherapy, patients with leptomeningeal metastasis (LM) from breast cancer were randomised to treatment including intraventricular (IT) chemotherapy (n=17) or to non-intrathecal (non-IT) treatment (n=18). Appropriate systemic therapy and involved field radiation therapy (RT) were given in both arms. Intention-to-treat analysis showed neurological improvement or stabilisation in 59% of the IT and in 67% of the non-IT group, with median time to progression of 23 weeks (IT) and 24 weeks (non-IT). Median survival of IT patients was 18.3 weeks and 30.3 weeks for non-IT patients (difference 12.9 weeks; 95% Confidence Interval (CI) -5.5 to +34.3 weeks; P=0.32). Neurological complications of treatment occurred in 47% (IT) vs 6% (non-IT) (P=0.0072). In conclusion, standard systemic chemotherapy with involved field RT for LM from breast cancer is feasible. Addition of intraventricular chemotherapy does not lead to survival benefit or improved neurological response, and is associated with an increased risk of neurotoxicity.

Abstract
In this single-center retrospective study, 155 consecutive patients with leptomeningeal metastasis (LM) were analyzed for the prognostic role of patient- and therapy-related variables. Ten percent of the patients received radiotherapy alone, 32% had chemotherapy alone, 31% received radiochemotherapy, 17% had supportive therapy only, and 10% were not evaluable for therapy. Chemotherapy was systemic (17%), combined systemic and intrathecal (10%), or intrathecal only (35%). Clinical improvement was noted in 41% of the patients. Overall median survival time (MST) was 4.8 months. Survival varied considerably depending on the type of primary tumor in this largest published cohort of LM patients. Univariate Cox regression analysis revealed that age >60 and elevated cerebrospinal fluid (CSF) albumin or lactate levels were therapy-independent predictors of poor survival in the entire cohort as well as in the subgroup of patients with systemic primary tumors (n=105). The assessment of three therapy-independent parameters allows to group LM patients into groups of low, intermediate, and high risk of poor survival. Moreover, the application of systemic chemotherapy was a positive prognostic factor in patients with subarachnoid lesions detected by neuroimaging (RR 1.94, p=0.001) or with extra-CNS tumor deposits (RR 1.52, p=0.05). The results of this study suggest that systemic chemotherapy alone or in combination with other therapeutic modalities may improve outcome in patients with subarachnoid tumor cell deposits detectable by neuroimaging.

Abstract
As systemic therapy of metastatic breast cancer improves, CNS involvement is becoming a more widespread problem. This article summarizes the current knowledge regarding the incidence, clinical presentation, diagnosis, prognosis, and treatment of CNS metastases in patients with breast cancer. When available, studies specific to breast cancer are presented; in studies in which many solid tumors were evaluated together, the proportion of patients with breast cancer is noted. On the basis of data from randomized trials and retrospective series, neurosurgery and stereotactic radiosurgery (SRS) may prolong survival in patients with single brain metastases. The treatment of multiple metastases remains controversial, as does the routine use of whole-brain radiotherapy (WBRT) after either surgery or SRS. Although it is widely assumed that chemotherapy is of limited benefit, data from case series and case reports suggest otherwise. WBRT, neurosurgery, SRS, and medical therapy each have a role in the treatment of CNS metastases; however, neurologic symptoms frequently are not fully reversible, even with appropriate therapy. Studies specifically targeted toward this group of patients are needed.

Abstract
Under the sponsorship of the International Extranodal Lymphoma Study Group, a Multidisciplinary Workshop on primary CNS lymphoma (PCNSL) with over 50 participants from Europe, North America, Israel, and Australia was held as part of the Eighth International Conference on Malignant Lymphoma in Lugano, Switzerland (June 12 to 15, 2002). The main purposes of the Workshop were to exchange the latest scientific information, to analyze methodologic issues in the design of clinical trials, to reach a consensus on treatment recommendations and prognostic factors, to discuss clinical and molecular targets for future studies, and to establish an international collaborative group to conduct laboratory and clinical investigations in PCNSL. This article summarizes the contents of the Workshop, analyzes the current knowledge on the most relevant biologic and clinical issues in PCNSL, and focuses on fundamental challenges to be addressed in future studies.

Abstract
Intrathecal chemotherapy has been the mainstay treatment for meningeal carcinomatosis for decades. However, this has not been the case with non-small cell lung cancer (NSCLC), due to the low efficacy of the drugs that could be used before. Gemcitabine is an effective drug against NSCLC and has a structure similar to cytarabine, which has been widely used in intrathecal chemotherapy. Thus, intrathecal gemcitabine chemotherapy might prove to be suitable for leptomeningeal carcinomatosis induced by NSCLC. We herein report our experience using gemcitabine intrathecal injections in a NSCLC patient with leptomeningeal carcinomatosis.

Abstract
Metastasis to the leptomeninges occurs in many common cancers, including leukemia; lung, breast, and gastrointestinal cancers; and tumors of the brain. By way of the flow of cerebrospinal fluid, leptomeningeal metastasis spreads throughout the neuraxis. Consequently, therapy for leptomeningeal metastasis must be directed to the entire central nervous system (CNS). Treatment often consists of involved-field radiotherapy, systemic chemotherapy, and intrathecal chemotherapy. However, because meningeal spread occurs most often in advanced disease, treatment is mainly palliative, except in childhood leukemia, where durable remission has been reported. This article outlines the role of systemic and intrathecal chemotherapy in patients with leptomeningeal metastases. Strategies for symptom management in these patients are also described.

Abstract
Neoplastic seeding of the leptomeninges often signifies limited life expectancy. Still, patients are frequently offered aggressive multimodality therapies to palliate symptoms, and, one hopes, to prolong survival. Treatment modalities directed at the central nervous system (CNS) include radiotherapy, intra-cerebrospinal fluid (CSF) chemotherapy, standard systemic chemotherapy, and systemic high-dose chemotherapy. Because many of these modalities are used in combination, it is often difficult to discern which mode is the predominant cause of either acute or delayed complications. This review summarizes the incidence, clinical manifestations, laboratory findings, and pathology related to acute and delayed toxicity of treatment. It describes complications associated with radiotherapy, the use of an intraventricular implanted device (ie, Ommaya device), adverse effects of intra-CSF chemotherapy, and neurotoxicity, either associated with high-dose chemotherapy or manifested as delayed and chronic complications of combined therapies. All CNS-directed therapies are associated with a high rate of complications. The adverse effects of therapy profoundly affect the patient's quality of life, both at the acute phase of treatment and in late and chronic complications after therapy is completed. Intra-CSF chemotherapy is associated with a high rate of acute, reversible adverse effects that sometimes evolve into life-threatening medical conditions. Devastating delayed complications, mainly described as leukoencephalopathy, develop in more than 50% of patients who survive for extended periods and often lead to progressive loss of cognitive capacities. Careful assessment of the benefits and potential adverse reactions to a particular therapy regimen is mandated.
